Anarchism is a political philosophy and movement that is sceptical of authority and rejects all involuntary, coercive forms of hierarchy. Anarchism calls for the abolition of the state, which it holds to be unnecessary, undesirable, and harmful. As a historically left-wing movement, placed on the farthest left of the political spectrum, it is usually described alongside communalism and libertarian Marxism as the libertarian wing (libertarian socialism) of the socialist movement, and has a strong historical association with anti-capitalism and socialism. Humans lived in societies without formal hierarchies long before the establishment of formal states, realms, or empires. With the rise of organised hierarchical bodies, scepticism toward authority also rose. Although traces of anarchist thought are found throughout history, modern anarchism emerged from the Enlightenment. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Paris Commune, the Russian Civil War and the Spanish Civil War, whose end marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more. Anarchism employs a diversity of tactics in order to meet its ideal ends which can be broadly separated into revolutionary and evolutionary tactics; there is significant overlap between the two, which are merely descriptive. Revolutionary tactics aim to bring down authority and state, having taken a violent turn in the past, while evolutionary tactics aim to prefigure what an anarchist society would be like. Anarchist thought, criticism, and praxis have played a part in diverse areas of human society. Criticism of anarchism include claims that it is internally inconsistent, violent, or utopian. Etymology, terminology, and definition The etymological origin of anarchism is from the Ancient Greek anarkhia, meaning "without a ruler", composed of the prefix an- ("without") and the word arkhos ("leader" or "ruler"). The suffix -ism denotes the ideological current that favours anarchy. Anarchism appears in English from 1642 as anarchisme and anarchy from 1539; early English usages emphasised a sense of disorder. Various factions within the French Revolution labelled their opponents as anarchists, although few such accused shared many views with later anarchists. Many revolutionaries of the 19th century such as William Godwin (1756–1836) and Wilhelm Weitling (1808–1871) would contribute to the anarchist doctrines of the next generation but did not use anarchist or anarchism in describing themselves or their beliefs. The first political philosopher to call himself an anarchist () was Pierre-Joseph Proudhon (1809–1865), marking the formal birth of anarchism in the mid-19th century. Since the 1890s and beginning in France, libertarianism has often been used as a synonym for anarchism and its use as a synonym is still common outside the United States. Some usages of libertarianism refer to individualistic free-market philosophy only, and free-market anarchism in particular is termed libertarian anarchism. While the term libertarian has been largely synonymous with anarchism, its meaning has more recently diluted with wider adoption from ideologically disparate groups, including both the New Left and libertarian Marxists, who do not associate themselves with authoritarian socialists or a vanguard party, and extreme cultural liberals, who are primarily concerned with civil liberties. Additionally, some anarchists use libertarian socialist to avoid anarchism's negative connotations and emphasise its connections with socialism. Anarchism is broadly used to describe the anti-authoritarian wing of the socialist movement. Anarchism is contrasted to socialist forms which are state-oriented or from above. Scholars of anarchism generally highlight anarchism's socialist credentials and criticise attempts at creating dichotomies between the two. Some scholars describe anarchism as having many influences from liberalism, and being both liberals and socialists but more so, while most scholars reject anarcho-capitalism as a misunderstanding of anarchist principles. While opposition to the state is central to anarchist thought, defining anarchism is not an easy task for scholars, as there is a lot of discussion among scholars and anarchists on the matter, and various currents perceive anarchism slightly differently. Major definitional elements include the will for a non-coercive society, the rejection of the state apparatus, the belief that human nature allows humans to exist in or progress toward such a non-coercive society, and a suggestion on how to act to pursue the ideal of anarchy. History Pre-modern era Before the establishment of towns and cities, an established authority did not exist. It was after the creation of institutions of authority that anarchistic ideas espoused as a reaction. The most notable precursors to anarchism in the ancient world were in China and Greece. In China, philosophical anarchism (the discussion on the legitimacy of the state) was delineated by Taoist philosophers Zhuang Zhou and Laozi. Alongside Stoicism, Taoism has been said to have had "significant anticipations" of anarchism. Anarchic attitudes were also articulated by tragedians and philosophers in Greece. Aeschylus and Sophocles used the myth of Antigone to illustrate the conflict between rules set by the state and personal autonomy. Socrates questioned Athenian authorities constantly and insisted on the right of individual freedom of conscience. Cynics dismissed human law (nomos) and associated authorities while trying to live according to nature (physis). Stoics were supportive of a society based on unofficial and friendly relations among its citizens without the presence of a state. In medieval Europe, there was no anarchistic activity except some ascetic religious movements. These, and other Muslim movements, later gave birth to religious anarchism. In the Sasanian Empire, Mazdak called for an egalitarian society and the abolition of monarchy, only to be soon executed by Emperor Kavad I. In Basra, religious sects preached against the state. In Europe, various sects developed anti-state and libertarian tendencies. Renewed interest in antiquity during the Renaissance and in private judgment during the Reformation restored elements of anti-authoritarian secularism, particularly in France. Enlightenment challenges to intellectual authority (secular and religious) and the revolutions of the 1790s and 1848 all spurred the ideological development of what became the era of classical anarchism. Modern era During the French Revolution, partisan groups such as the Enragés and the saw a turning point in the fermentation of anti-state and federalist sentiments. The first anarchist currents developed throughout the 18th century as William Godwin espoused philosophical anarchism in England, morally delegitimising the state, Max Stirner's thinking paved the way to individualism and Pierre-Joseph Proudhon's theory of mutualism found fertile soil in France. By the late 1870s, various anarchist schools of thought had become well-defined and a wave of then unprecedented globalisation occurred from 1880 to 1914. This era of classical anarchism lasted until the end of the Spanish Civil War and is considered the golden age of anarchism. Drawing from mutualism, Mikhail Bakunin founded collectivist anarchism and entered the International Workingmen's Association, a class worker union later known as the First International that formed in 1864 to unite diverse revolutionary currents. The International became a significant political force, with Karl Marx being a leading figure and a member of its General Council. Bakunin's faction (the Jura Federation) and Proudhon's followers (the mutualists) opposed state socialism, advocating political abstentionism and small property holdings. After bitter disputes, the Bakuninists were expelled from the International by the Marxists at the 1872 Hague Congress. Anarchists were treated similarly in the Second International, being ultimately expelled in 1896. Bakunin famously predicted that if revolutionaries gained power by Marx's terms, they would end up the new tyrants of workers. In response to their expulsion from the First International, anarchists formed the St. Imier International. Under the influence of Peter Kropotkin, a Russian philosopher and scientist, anarcho-communism overlapped with collectivism. Anarcho-communists, who drew inspiration from the 1871 Paris Commune, advocated for free federation and for the distribution of goods according to one's needs. At the turn of the century, anarchism had spread all over the world. It was a notable feature of the international syndicalism movement. In China, small groups of students imported the humanistic pro-science version of anarcho-communism. Tokyo was a hotspot for rebellious youth from countries of the far east, travelling to the Japanese capital to study. In Latin America, Argentina was a stronghold for anarcho-syndicalism, where it became the most prominent left-wing ideology. During this time, a minority of anarchists adopted tactics of revolutionary political violence. This strategy became known as propaganda of the deed. The dismemberment of the French socialist movement into many groups and the execution and exile of many Communards to penal colonies following the suppression of the Paris Commune favoured individualist political expression and acts. Even though many anarchists distanced themselves from these terrorist acts, infamy came upon the movement and attempts were made to exclude them from American immigration, including the Immigration Act of 1903, also called the Anarchist Exclusion Act. Illegalism was another strategy which some anarchists adopted during this period. Despite concerns, anarchists enthusiastically participated in the Russian Revolution in opposition to the White movement; however, they met harsh suppression after the Bolshevik government was stabilised. Several anarchists from Petrograd and Moscow fled to Ukraine, notably leading to the Kronstadt rebellion and Nestor Makhno's struggle in the Free Territory. With the anarchists being crushed in Russia, two new antithetical currents emerged, namely platformism and synthesis anarchism. The former sought to create a coherent group that would push for revolution while the latter were against anything that would resemble a political party. Seeing the victories of the Bolsheviks in the October Revolution and the resulting Russian Civil War, many workers and activists turned to communist parties which grew at the expense of anarchism and other socialist movements. In France and the United States, members of major syndicalist movements such as the General Confederation of Labour and the Industrial Workers of the World left their organisations and joined the Communist International. In the Spanish Civil War of 1936, anarchists and syndicalists (CNT and FAI) once again allied themselves with various currents of leftists. A long tradition of Spanish anarchism led to anarchists playing a pivotal role in the war. In response to the army rebellion, an anarchist-inspired movement of peasants and workers, supported by armed militias, took control of Barcelona and of large areas of rural Spain, where they collectivised the land. The Soviet Union provided some limited assistance at the beginning of the war, but the result was a bitter fight among communists and anarchists at a series of events named May Days as Joseph Stalin tried to seize control of the Republicans. Post-war era At the end of World War II, the anarchist movement was severely weakened. The 1960s witnessed a revival of anarchism, likely caused by a perceived failure of Marxism–Leninism and tensions built by the Cold War. During this time, anarchism found a presence in other movements critical towards both capitalism and the state such as the anti-nuclear, environmental, and peace movements, the counterculture of the 1960s, and the New Left. It also saw a transition from its previous revolutionary nature to provocative anti-capitalist reformism. Anarchism became associated with punk subculture as exemplified by bands such as Crass and the Sex Pistols. The established feminist tendencies of anarcha-feminism returned with vigour during the second wave of feminism. Black anarchism began to take form at this time and influenced anarchism's move from a Eurocentric demographic. This coincided with its failure to gain traction in Northern Europe and its unprecedented height in Latin America. Around the turn of the 21st century, anarchism grew in popularity and influence within anti-capitalist, anti-war and anti-globalisation movements. Anarchists became known for their involvement in protests against the World Trade Organization (WTO), the Group of Eight and the World Economic Forum. During the protests, ad hoc leaderless anonymous cadres known as black blocs engaged in rioting, property destruction and violent confrontations with the police. Other organisational tactics pioneered in this time include affinity groups, security culture and the use of decentralised technologies such as the Internet. A significant event of this period was the confrontations at the 1999 Seattle WTO conference. Anarchist ideas have been influential in the development of the Zapatistas in Mexico and the Democratic Federation of Northern Syria, more commonly known as Rojava, a de facto autonomous region in northern Syria. Thought Anarchist schools of thought have been generally grouped into two main historical traditions, social anarchism and individualist anarchism, owing to their different origins, values and evolution. The individualist current emphasises negative liberty in opposing restraints upon the free individual, while the social current emphasises positive liberty in aiming to achieve the free potential of society through equality and social ownership. In a chronological sense, anarchism can be segmented by the classical currents of the late 19th century and the post-classical currents (anarcha-feminism, green anarchism, and post-anarchism) developed thereafter. Beyond the specific factions of anarchist movements which constitute political anarchism lies philosophical anarchism which holds that the state lacks moral legitimacy, without necessarily accepting the imperative of revolution to eliminate it. A component especially of individualist anarchism, philosophical anarchism may tolerate the existence of a minimal state but claims that citizens have no moral obligation to obey government when it conflicts with individual autonomy. Anarchism pays significant attention to moral arguments since ethics have a central role in anarchist philosophy. Anarchism's emphasis on anti-capitalism, egalitarianism, and for the extension of community and individuality sets it apart from anarcho-capitalism and other types of economic libertarianism. Anarchism is usually placed on the far-left of the political spectrum. Much of its economics and legal philosophy reflect anti-authoritarian, anti-statist, libertarian, and radical interpretations of left-wing and socialist politics such as collectivism, communism, individualism, mutualism, and syndicalism, among other libertarian socialist economic theories. As anarchism does not offer a fixed body of doctrine from a single particular worldview, many anarchist types and traditions exist and varieties of anarchy diverge widely. One reaction against sectarianism within the anarchist milieu was anarchism without adjectives, a call for toleration and unity among anarchists first adopted by Fernando Tarrida del Mármol in 1889 in response to the bitter debates of anarchist theory at the time. Belief in political nihilism has been espoused by anarchists. Despite separation, the various anarchist schools of thought are not seen as distinct entities but rather as tendencies that intermingle and are connected through a set of uniform principles such as individual and local autonomy, mutual aid, network organisation, communal democracy, justified authority and decentralisation. Classical Inceptive currents among classical anarchist currents were mutualism and individualism. They were followed by the major currents of social anarchism (collectivist, communist and syndicalist). They differ on organisational and economic aspects of their ideal society. Mutualism is an 18th-century economic theory that was developed into anarchist theory by Pierre-Joseph Proudhon. Its aims include reciprocity, free association, voluntary contract, federation and monetary reform of both credit and currency that would be regulated by a bank of the people. Mutualism has been retrospectively characterised as ideologically situated between individualist and collectivist forms of anarchism. In What Is Property? (1840), Proudhon first characterised his goal as a "third form of society, the synthesis of communism and property." Collectivist anarchism is a revolutionary socialist form of anarchism commonly associated with Mikhail Bakunin. Collectivist anarchists advocate collective ownership of the means of production which is theorised to be achieved through violent revolution and that workers be paid according to time worked, rather than goods being distributed according to need as in communism. Collectivist anarchism arose alongside Marxism but rejected the dictatorship of the proletariat despite the stated Marxist goal of a collectivist stateless society. Anarcho-communism is a theory of anarchism that advocates a communist society with common ownership of the means of production, direct democracy and a horizontal network of voluntary associations, workers' councils and worker cooperatives, with production and consumption based on the guiding principle "From each according to his ability, to each according to his need." Anarcho-communism developed from radical socialist currents after the French Revolution but was first formulated as such in the Italian section of the First International. It was later expanded upon in the theoretical work of Peter Kropotkin, whose specific style would go onto become the dominating view of anarchists by the late 19th century. Anarcho-syndicalism is a branch of anarchism that views labour syndicates as a potential force for revolutionary social change, replacing capitalism and the state with a new society democratically self-managed by workers. The basic principles of anarcho-syndicalism are direct action, workers' solidarity and workers' self-management. Individualist anarchism is a set of several traditions of thought within the anarchist movement that emphasise the individual and their will over any kinds of external determinants. Early influences on individualist forms of anarchism include William Godwin, Max Stirner, and Henry David Thoreau. Through many countries, individualist anarchism attracted a small yet diverse following of Bohemian artists and intellectuals as well as young anarchist outlaws in what became known as illegalism and individual reclamation. Post-classical and contemporary Anarchist principles undergird contemporary radical social movements of the left. Interest in the anarchist movement developed alongside momentum in the anti-globalisation movement, whose leading activist networks were anarchist in orientation. As the movement shaped 21st century radicalism, wider embrace of anarchist principles signaled a revival of interest. Anarchism has continued to generate many philosophies and movements, at times eclectic, drawing upon various sources and combining disparate concepts to create new philosophical approaches. The anti-capitalist tradition of classical anarchism has remained prominent within contemporary currents. Contemporary news coverage which emphasizes black bloc demonstrations has reinforced anarchism's historical association with chaos and violence. Its publicity has also led more scholars in fields such as anthropology and history to engage with the anarchist movement, although contemporary anarchism favours actions over academic theory. Various anarchist groups, tendencies, and schools of thought exist today, making it difficult to describe the contemporary anarchist movement. While theorists and activists have established "relatively stable constellations of anarchist principles", there is no consensus on which principles are core and commentators describe multiple anarchisms, rather than a singular anarchism, in which common principles are shared between schools of anarchism while each group prioritizes those principles differently. Gender equality can be a common principle, although it ranks as a higher priority to anarcha-feminists than anarcho-communists. Anarchists are generally committed against coercive authority in all forms, namely "all centralized and hierarchical forms of government (e.g., monarchy, representative democracy, state socialism, etc.), economic class systems (e.g., capitalism, Bolshevism, feudalism, slavery, etc.), autocratic religions (e.g., fundamentalist Islam, Roman Catholicism, etc.), patriarchy, heterosexism, white supremacy, and imperialism." Anarchist schools disagree on the methods by which these forms should be opposed. The principle of equal liberty is closer to anarchist political ethics in that it transcends both the liberal and socialist traditions. This entails that liberty and equality cannot be implemented within the state, resulting in the questioning of all forms of domination and hierarchy. Tactics Anarchists' tactics take various forms but in general serve two major goals, namely to first oppose the Establishment and secondly to promote anarchist ethics and reflect an anarchist vision of society, illustrating the unity of means and ends. A broad categorisation can be made between aims to destroy oppressive states and institutions by revolutionary means on one hand and aims to change society through evolutionary means on the other. Evolutionary tactics embrace nonviolence, reject violence and take a gradual approach to anarchist aims, although there is significant overlap between the two. Anarchist tactics have shifted during the course of the last century. Anarchists during the early 20th century focused more on strikes and militancy while contemporary anarchists use a broader array of approaches. Classical era tactics During the classical era, anarchists had a militant tendency. Not only did they confront state armed forces, as in Spain and Ukraine, but some of them also employed terrorism as propaganda of the deed. Assassination attempts were carried out against heads of state, some of which were successful. Anarchists also took part in revolutions. Many anarchists, especially the Galleanists, believed that these attempts would be the impetus for a revolution against capitalism and the state. Many of these attacks were done by individual assailants and the majority took place in the late 1870s, the early 1880s and the 1890s, with some still occurring in the early 1900s. Their decrease in prevalence was the result of further judicial power and targeting and cataloging by state institutions. Anarchist perspectives towards violence have always been controversial. Anarcho-pacifists advocate for non-violence means to achieve their stateless, nonviolent ends. Other anarchist groups advocate direct action, a tactic which can include acts of sabotage or terrorism. This attitude was quite prominent a century ago when seeing the state as a tyrant and some anarchists believing that they had every right to oppose its oppression by any means possible. Emma Goldman and Errico Malatesta, who were proponents of limited use of violence, stated that violence is merely a reaction to state violence as a necessary evil. Anarchists took an active role in strike actions, although they tended to be antipathetic to formal syndicalism, seeing it as reformist. They saw it as a part of the movement which sought to overthrow the state and capitalism. Anarchists also reinforced their propaganda within the arts, some of whom practiced naturism and nudism. Those anarchists also built communities which were based on friendship and were involved in the news media. Revolutionary tactics In the current era, Italian anarchist Alfredo Bonanno, a proponent of insurrectionary anarchism, has reinstated the debate on violence by rejecting the nonviolence tactic adopted since the late 19th century by Kropotkin and other prominent anarchists afterwards. Both Bonanno and the French group The Invisible Committee advocate for small, informal affiliation groups, where each member is responsible for their own actions but works together to bring down oppression utilizing sabotage and other violent means against state, capitalism, and other enemies. Members of The Invisible Committee were arrested in 2008 on various charges, terrorism included. Overall, contemporary anarchists are much less violent and militant than their ideological ancestors. They mostly engage in confronting the police during demonstrations and riots, especially in countries such as Canada, Greece, and Mexico. Militant black bloc protest groups are known for clashing with the police; however, anarchists not only clash with state operators, they also engage in the struggle against fascists and racists, taking anti-fascist action and mobilizing to prevent hate rallies from happening. Evolutionary tactics Anarchists commonly employ direct action. This can take the form of disrupting and protesting against unjust hierarchy, or the form of self-managing their lives through the creation of counter-institutions such as communes and non-hierarchical collectives. Decision-making is often handled in an anti-authoritarian way, with everyone having equal say in each decision, an approach known as horizontalism. Contemporary-era anarchists have been engaging with various grassroots movements that are more or less based on horizontalism, although not explicitly anarchist, respecting personal autonomy and participating in mass activism such as strikes and demonstrations. In contrast with the big-A anarchism of the classical era, the newly coined term small-a anarchism signals their tendency not to base their thoughts and actions on classical-era anarchism or to refer to classical anarchists such as Peter Kropotkin and Pierre-Joseph Proudhon to justify their opinions. Those anarchists would rather base their thought and praxis on their own experience which they will later theorize. The decision-making process of small anarchist affinity groups plays a significant tactical role. Anarchists have employed various methods in order to build a rough consensus among members of their group without the need of a leader or a leading group. One way is for an individual from the group to play the role of facilitator to help achieve a consensus without taking part in the discussion themselves or promoting a specific point. Minorities usually accept rough consensus, except when they feel the proposal contradicts anarchist ethics, goals and values. Anarchists usually form small groups (5–20 individuals) to enhance autonomy and friendships among their members. These kinds of groups more often than not interconnect with each other, forming larger networks. Anarchists still support and participate in strikes, especially wildcat strikes as these are leaderless strikes not organised centrally by a syndicate. As in the past, newspapers and journals are used, and anarchists have gone online in the World Wide Web to spread their message. Anarchists have found it easier to create websites because of distributional and other difficulties, hosting electronic libraries and other portals. Anarchists were also involved in developing various software that are available for free. The way these hacktivists work to develop and distribute resembles the anarchist ideals, especially when it comes to preserving users' privacy from state surveillance. Anarchists organize themselves to squat and reclaim public spaces. During important events such as protests and when spaces are being occupied, they are often called Temporary Autonomous Zones (TAZ), spaces where art, poetry, and surrealism are blended to display the anarchist ideal. As seen by anarchists, squatting is a way to regain urban space from the capitalist market, serving pragmatical needs and also being an exemplary direct action. Acquiring space enables anarchists to experiment with their ideas and build social bonds. Adding up these tactics while having in mind that not all anarchists share the same attitudes towards them, along with various forms of protesting at highly symbolic events, make up a carnivalesque atmosphere that is part of contemporary anarchist vividity. Key issues As anarchism is a philosophy that embodies many diverse attitudes, tendencies, and schools of thought; disagreement over questions of values, ideology, and tactics is common. Its diversity has led to widely different uses of identical terms among different anarchist traditions which has created a number of definitional concerns in anarchist theory. The compatibility of capitalism, nationalism, and religion with anarchism is widely disputed, and anarchism enjoys complex relationships with ideologies such as communism, collectivism, Marxism, and trade unionism. Anarchists may be motivated by humanism, divine authority, enlightened self-interest, veganism, or any number of alternative ethical doctrines. Phenomena such as civilisation, technology (e.g. within anarcho-primitivism), and the democratic process may be sharply criticised within some anarchist tendencies and simultaneously lauded in others. Gender, sexuality, and free love As gender and sexuality carry along them dynamics of hierarchy, many anarchists address, analyse, and oppose the suppression of one's autonomy imposed by gender roles. Sexuality was not often discussed by classical anarchists but the few that did felt that an anarchist society would lead to sexuality naturally developing. Sexual violence was a concern for anarchists such as Benjamin Tucker, who opposed age of consent laws, believing they would benefit predatory men. A historical current that arose and flourished during 1890 and 1920 within anarchism was free love. In contemporary anarchism, this current survives as a tendency to support polyamory and queer anarchism. Free love advocates were against marriage, which they saw as a way of men imposing authority over women, largely because marriage law greatly favoured the power of men. The notion of free love was much broader and included a critique of the established order that limited women's sexual freedom and pleasure. Those free love movements contributed to the establishment of communal houses, where large groups of travelers, anarchists and other activists slept in beds together. Free love had roots both in Europe and the United States; however, some anarchists struggled with the jealousy that arose from free love. Anarchist feminists were advocates of free love, against marriage, and pro-choice (utilising a contemporary term), and had a similar agenda. Anarchist and non-anarchist feminists differed on suffrage but were supportive of one another. During the second half of the 20th century, anarchism intermingled with the second wave of feminism, radicalising some currents of the feminist movement and being influenced as well. By the latest decades of the 20th century, anarchists and feminists were advocating for the rights and autonomy of women, gays, queers and other marginalised groups, with some feminist thinkers suggesting a fusion of the two currents. With the third wave of feminism, sexual identity and compulsory heterosexuality became a subject of study for anarchists, yielding a post-structuralist critique of sexual normality. Some anarchists distanced themselves from this line of thinking, suggesting that it leaned towards an individualism that was dropping the cause of social liberation. Anarchism and education The interest of anarchists in education stretches back to the first emergence of classical anarchism. Anarchists consider proper education, one which sets the foundations of the future autonomy of the individual and the society, to be an act of mutual aid. Anarchist writers such as William Godwin (Political Justice) and Max Stirner ("The False Principle of Our Education") attacked both state education and private education as another means by which the ruling class replicate their privileges. In 1901, Catalan anarchist and free thinker Francisco Ferrer established the Escuela Moderna in Barcelona as an opposition to the established education system which was dictated largely by the Catholic Church. Ferrer's approach was secular, rejecting both state and church involvement in the educational process whilst giving pupils large amounts of autonomy in planning their work and attendance. Ferrer aimed to educate the working class and explicitly sought to foster class consciousness among students. The school closed after constant harassment by the state and Ferrer was later arrested. Nonetheless, his ideas formed the inspiration for a series of modern schools around the world. Christian anarchist Leo Tolstoy, who published the essay Education and Culture, also established a similar school with its founding principle being that "for education to be effective it had to be free." In a similar token, A. S. Neill founded what became the Summerhill School in 1921, also declaring being free from coercion. Anarchist education is based largely on the idea that a child's right to develop freely and without manipulation ought to be respected and that rationality would lead children to morally good conclusions; however, there has been little consensus among anarchist figures as to what constitutes manipulation. Ferrer believed that moral indoctrination was necessary and explicitly taught pupils that equality, liberty and social justice were not possible under capitalism, along with other critiques of government and nationalism. Late 20th century and contemporary anarchist writers (Paul Goodman, Herbert Read, and Colin Ward) intensified and expanded the anarchist critique of state education, largely focusing on the need for a system that focuses on children's creativity rather than on their ability to attain a career or participate in consumerism as part of a consumer society. Contemporary anarchists such as Ward claim that state education serves to perpetuate socioeconomic inequality. While few anarchist education institutions have survived to the modern-day, major tenets of anarchist schools, among them respect for child autonomy and relying on reasoning rather than indoctrination as a teaching method, have spread among mainstream educational institutions. Judith Suissa names three schools as explicitly anarchists schools, namely the Free Skool Santa Cruz in the United States which is part of a wider American-Canadian network of schools, the Self-Managed Learning College in Brighton, England, and the Paideia School in Spain. Anarchism and the state Objection to the state and its institutions is a sine qua non of anarchism. Anarchists consider the state as a tool of domination and believe it to be illegitimate regardless of its political tendencies. Instead of people being able to control the aspects of their life, major decisions are taken by a small elite. Authority ultimately rests solely on power, regardless of whether that power is open or transparent, as it still has the ability to coerce people. Another anarchist argument against states is that the people constituting a government, even the most altruistic among officials, will unavoidably seek to gain more power, leading to corruption. Anarchists consider the idea that the state is the collective will of the people to be an unachievable fiction due to the fact that the ruling class is distinct from the rest of society. Specific anarchist attitudes towards the state vary. Robert Paul Wolff believed that the tension between authority and autonomy would mean the state could never be legitimate. Bakunin saw the state as meaning "coercion, domination by means of coercion, camouflaged if possible but unceremonious and overt if need be." A. John Simmons and Leslie Green, who leaned toward philosophical anarchism, believed that the state could be legitimate if it is governed by consensus, although they saw this as highly unlikely. Beliefs on how to abolish the state also differ. Anarchism and the arts The connection between anarchism and art was quite profound during the classical era of anarchism, especially among artistic currents that were developing during that era such as futurists, surrealists and others. In literature, anarchism was mostly associated with the New Apocalyptics and the neo-romanticism movement. In music, anarchism has been associated with music scenes such as punk. Anarchists such as Leo Tolstoy and Herbert Read stated that the border between the artist and the non-artist, what separates art from a daily act, is a construct produced by the alienation caused by capitalism and it prevents humans from living a joyful life. Other anarchists advocated for or used art as a means to achieve anarchist ends. In his book Breaking the Spell: A History of Anarchist Filmmakers, Videotape Guerrillas, and Digital Ninjas, Chris Robé claims that "anarchist-inflected practices have increasingly structured movement-based video activism." Throughout the 20th century, many prominent anarchists (Peter Kropotkin, Emma Goldman, Gustav Landauer and Camillo Berneri) and publications such as Anarchy wrote about matters pertaining to the arts. Three overlapping properties made art useful to anarchists. It could depict a critique of existing society and hierarchies, serve as a prefigurative tool to reflect the anarchist ideal society and even turn into a means of direct action such as in protests. As it appeals to both emotion and reason, art could appeal to the whole human and have a powerful effect. The 19th-century neo-impressionist movement had an ecological aesthetic and offered an example of an anarchist perception of the road towards socialism. In Les chataigniers a Osny by anarchist painter Camille Pissarro, the blending of aesthetic and social harmony is prefiguring an ideal anarchistic agrarian community. Analysis The most common critique of anarchism is that humans cannot self-govern and so a state is necessary for human survival. Philosopher Bertrand Russell supported this critique, stating that "[p]eace and war, tariffs, regulations of sanitary conditions and the sale of noxious drugs, the preservation of a just system of distribution: these, among others, are functions which could hardly be performed in a community in which there was no central government." Another common criticism of anarchism is that it fits a world of isolation in which only the small enough entities can be self-governing; a response would be that major anarchist thinkers advocated anarchist federalism. Philosophy lecturer Andrew G. Fiala composed a list of common arguments against anarchism which includes critiques such as that anarchism is innately related to violence and destruction, not only in the pragmatic world, such as at protests, but in the world of ethics as well. Secondly, anarchism is evaluated as unfeasible or utopian since the state cannot be defeated practically. This line of arguments most often calls for political action within the system to reform it. The third argument is that anarchism is self-contradictory. While it advocates for no-one to archiei, if accepted by the many, then anarchism would turn into the ruling political theory. In this line of criticism also comes the self-contradiction that anarchism calls for collective action whilst endorsing the autonomy of the individual, hence no collective action can be taken. Lastly, Fiala mentions a critique towards philosophical anarchism of being ineffective (all talk and thoughts) and in the meantime capitalism and bourgeois class remains strong. Philosophical anarchism has met the criticism of members of academia following the release of pro-anarchist books such as A. John Simmons' Moral Principles and Political Obligations. Law professor William A. Edmundson authored an essay to argue against three major philosophical anarchist principles which he finds fallacious. Edmundson says that while the individual does not owe the state a duty of obedience, this does not imply that anarchism is the inevitable conclusion and the state is still morally legitimate. In The Problem of Political Authority, Michael Huemer defends philosophical anarchism, claiming that "political authority is a moral illusion." One of the earliest criticisms is that anarchism defies and fails to understand the biological inclination to authority. Joseph Raz states that the acceptance of authority implies the belief that following their instructions will afford more success. Raz believes that this argument is true in following both authorities' successful and mistaken instruction. Anarchists reject this criticism because challenging or disobeying authority does not entail the disappearance of its advantages by acknowledging authority such as doctors or lawyers as reliable, nor does it involve a complete surrender of independent judgment. Anarchist perception of human nature, rejection of the state, and commitment to social revolution has been criticised by academics as naive, overly simplistic, and unrealistic, respectively. Classical anarchism has been criticised for relying too heavily on the belief that the abolition of the state will lead to human cooperation prospering. Friedrich Engels, considered to be one of the principal founders of Marxism, criticised anarchism's anti-authoritarianism as inherently counter-revolutionary because in his view a revolution is by itself authoritarian. Academic John Molyneux writes in his book Anarchism: A Marxist Criticism that "anarchism cannot win", believing that it lacks the ability to properly implement its ideas. The Marxist criticism of anarchism is that it has a utopian character because all individuals should have anarchist views and values. According to the Marxist view, that a social idea would follow directly from this human ideal and out of the free will of every individual formed its essence. Marxists state that this contradiction was responsible for their inability to act. In the anarchist vision, the conflict between liberty and equality was resolved through coexistence and intertwining.

The Austroasiatic languages , also known as Mon–Khmer , are a large language family in Mainland Southeast Asia and South Asia. These languages are scattered throughout parts of Thailand, India, Bangladesh, Nepal, and southern China. There are around 117 million speakers of Austroasiatic languages. Of these languages, only Vietnamese, Khmer, and Mon have a long-established recorded history. Only two have official status as modern national languages: Vietnamese in Vietnam and Khmer in Cambodia. The Mon language is a recognized indigenous language in Myanmar and Thailand. In Myanmar, the Wa language is the de facto official language of Wa State. Santali is one of the 22 scheduled languages of India. The rest of the languages are spoken by minority groups and have no official status. Ethnologue identifies 168 Austroasiatic languages. These form thirteen established families (plus perhaps Shompen, which is poorly attested, as a fourteenth), which have traditionally been grouped into two, as Mon–Khmer, and Munda. However, one recent classification posits three groups (Munda, Nuclear Mon-Khmer, and Khasi–Khmuic), while another has abandoned Mon–Khmer as a taxon altogether, making it synonymous with the larger family. Austroasiatic languages have a disjunct distribution across Southeast Asia and parts of India, Bangladesh, Nepal and East Asia, separated by regions where other languages are spoken. They appear to be the extant original languages of Mainland Southeast Asia (excluding the Andaman Islands), with the neighboring, and sometimes surrounding, Kra–Dai, Hmong-Mien, Austronesian, and Sino-Tibetan languages being the result of later migrations. Etymology The name Austroasiatic comes from a combination of the Latin words for "South" and "Asia", hence "South Asia". Typology Regarding word structure, Austroasiatic languages are well known for having an iambic "sesquisyllabic" pattern, with basic nouns and verbs consisting of an initial, unstressed, reduced minor syllable followed by a stressed, full syllable. This reduction of presyllables has led to a variety among modern languages of phonological shapes of the same original Proto-Austroasiatic prefixes, such as the causative prefix, ranging from CVC syllables to consonant clusters to single consonants. As for word formation, most Austroasiatic languages have a variety of derivational prefixes, many have infixes, but suffixes are almost completely non-existent in most branches except Munda, and a few specialized exceptions in other Austroasiatic branches. The Austroasiatic languages are further characterized as having unusually large vowel inventories and employing some sort of register contrast, either between modal (normal) voice and breathy (lax) voice or between modal voice and creaky voice. Languages in the Pearic branch and some in the Vietic branch can have a three- or even four-way voicing contrast. However, some Austroasiatic languages have lost the register contrast by evolving more diphthongs or in a few cases, such as Vietnamese, tonogenesis. Vietnamese has been so heavily influenced by Chinese that its original Austroasiatic phonological quality is obscured and now resembles that of South Chinese languages, whereas Khmer, which had more influence from Sanskrit, has retained a more typically Austroasiatic structure. Proto-language Much work has been done on the reconstruction of Proto-Mon–Khmer in Harry L. Shorto's Mon–Khmer Comparative Dictionary. Little work has been done on the Munda languages, which are not well documented. With their demotion from a primary branch, Proto-Mon–Khmer becomes synonymous with Proto-Austroasiatic. Paul Sidwell (2005) reconstructs the consonant inventory of Proto-Mon–Khmer as follows: This is identical to earlier reconstructions except for . is better preserved in the Katuic languages, which Sidwell has specialized in. Internal classification Linguists traditionally recognize two primary divisions of Austroasiatic: the Mon–Khmer languages of Southeast Asia, Northeast India and the Nicobar Islands, and the Munda languages of East and Central India and parts of Bangladesh, parts of Nepal. However, no evidence for this classification has ever been published. Each of the families that is written in boldface type below is accepted as a valid clade. By contrast, the relationships between these families within Austroasiatic are debated. In addition to the traditional classification, two recent proposals are given, neither of which accepts traditional "Mon–Khmer" as a valid unit. However, little of the data used for competing classifications has ever been published, and therefore cannot be evaluated by peer review. In addition, there are suggestions that additional branches of Austroasiatic might be preserved in substrata of Acehnese in Sumatra (Diffloth), the Chamic languages of Vietnam, and the Land Dayak languages of Borneo (Adelaar 1995). Diffloth (1974) Diffloth's widely cited original classification, now abandoned by Diffloth himself, is used in Encyclopædia Britannica and—except for the breakup of Southern Mon–Khmer—in Ethnologue. Munda North Munda Korku Kherwarian South Munda Kharia–Juang Koraput Munda Mon–Khmer Eastern Mon–Khmer Khmer (Cambodian) Pearic Bahnaric Katuic Vietic (Vietnamese, Muong) Northern Mon–Khmer Khasi (Meghalaya, India) Palaungic Khmuic Southern Mon–Khmer Mon Aslian (Malaya) Nicobarese (Nicobar Islands) Peiros (2004) Peiros is a lexicostatistic classification, based on percentages of shared vocabulary. This means that languages can appear to be more distantly related than they actually are due to language contact. Indeed, when Sidwell (2009) replicated Peiros's study with languages known well enough to account for loans, he did not find the internal (branching) structure below. Nicobarese Munda–Khmer Munda Mon–Khmer Khasi Nuclear Mon–Khmer Mangic (Mang + Palyu) (perhaps in Northern MK) Vietic (perhaps in Northern MK) Northern Mon–Khmer Palaungic Khmuic Central Mon–Khmer Khmer dialects Pearic Asli-Bahnaric Aslian Mon–Bahnaric Monic Katu–Bahnaric Katuic Bahnaric Diffloth (2005) Diffloth compares reconstructions of various clades, and attempts to classify them based on shared innovations, though like other classifications the evidence has not been published. As a schematic, we have: Or in more detail, Munda languages (India) Koraput: 7 languages Core Munda languages Kharian–Juang: 2 languages North Munda languages Korku Kherwarian: 12 languages Khasi–Khmuic languages (Northern Mon–Khmer) Khasian: 3 languages of north eastern India and adjacent region of Bangladesh Palaungo-Khmuic languages Khmuic: 13 languages of Laos and Thailand Palaungo-Pakanic languages Pakanic or Palyu: 4 or 5 languages of southern China and Vietnam Palaungic: 21 languages of Burma, southern China, and Thailand Nuclear Mon–Khmer languages Khmero-Vietic languages (Eastern Mon–Khmer) Vieto-Katuic languages ? Vietic: 10 languages of Vietnam and Laos, including the Vietnamese language, which has the most speakers of any Austroasiatic language. Katuic: 19 languages of Laos, Vietnam, and Thailand. Khmero-Bahnaric languages Bahnaric: 40 languages of Vietnam, Laos, and Cambodia. Khmeric languages The Khmer dialects of Cambodia, Thailand, and Vietnam. Pearic: 6 languages of Cambodia. Nico-Monic languages (Southern Mon–Khmer) Nicobarese: 6 languages of the Nicobar Islands, a territory of India. Asli-Monic languages Aslian: 19 languages of peninsular Malaysia and Thailand. Monic: 2 languages, the Mon language of Burma and the Nyahkur language of Thailand. Sidwell (2009–2015) Paul Sidwell (2009), in a lexicostatistical comparison of 36 languages which are well known enough to exclude loanwords, finds little evidence for internal branching, though he did find an area of increased contact between the Bahnaric and Katuic languages, such that languages of all branches apart from the geographically distant Munda and Nicobarese show greater similarity to Bahnaric and Katuic the closer they are to those branches, without any noticeable innovations common to Bahnaric and Katuic. He therefore takes the conservative view that the thirteen branches of Austroasiatic should be treated as equidistant on current evidence. Sidwell & Blench (2011) discuss this proposal in more detail, and note that there is good evidence for a Khasi–Palaungic node, which could also possibly be closely related to Khmuic. If this would the case, Sidwell & Blench suggest that Khasic may have been an early offshoot of Palaungic that had spread westward. Sidwell & Blench (2011) suggest Shompen as an additional branch, and believe that a Vieto-Katuic connection is worth investigating. In general, however, the family is thought to have diversified too quickly for a deeply nested structure to have developed, since Proto-Austroasiatic speakers are believed by Sidwell to have radiated out from the central Mekong river valley relatively quickly. Subsequently, Sidwell (2015a: 179) proposed that Nicobarese subgroups with Aslian, just as how Khasian and Palaungic subgroup with each other. A subsequent computational phylogenetic analysis (Sidwell 2015b) suggests that Austroasiatic branches may have a loosely nested structure rather than a completely rake-like structure, with an east–west division (consisting of Munda, Khasic, Palaungic, and Khmuic forming a western group as opposed to all of the other branches) occurring possibly as early as 7,000 years before present. However, he still considers the subbranching dubious. Integrating computational phylogenetic linguistics with recent archaeological findings, Paul Sidwell (2015c) further expanded his Mekong riverine hypothesis by proposing that Austroasiatic had ultimately expanded into Indochina from the Lingnan area of southern China, with the subsequent Mekong riverine dispersal taking place after the initial arrival of Neolithic farmers from southern China. Sidwell (2015c) tentatively suggests that Austroasiatic may have begun to split up 5,000 years B.P. during the Neolithic transition era of mainland Southeast Asia, with all the major branches of Austroasiatic formed by 4,000 B.P. Austroasiatic would have had two possible dispersal routes from the western periphery of the Pearl River watershed of Lingnan, which would have been either a coastal route down the coast of Vietnam, or downstream through the Mekong River via Yunnan. Both the reconstructed lexicon of Proto-Austroasiatic and the archaeological record clearly show that early Austroasiatic speakers around 4,000 B.P. cultivated rice and millet, kept livestock such as dogs, pigs, and chickens, and thrived mostly in estuarine rather than coastal environments. At 4,500 B.P., this "Neolithic package" suddenly arrived in Indochina from the Lingnan area without cereal grains and displaced the earlier pre-Neolithic hunter-gatherer cultures, with grain husks found in northern Indochina by 4,100 B.P. and in southern Indochina by 3,800 B.P. However, Sidwell (2015c) found that iron is not reconstructable in Proto-Austroasiatic, since each Austroasiatic branch has different terms for iron that had been borrowed relatively lately from Tai, Chinese, Tibetan, Malay, and other languages. During the Iron Age about 2,500 B.P., relatively young Austroasiatic branches in Indochina such as Vietic, Katuic, Pearic, and Khmer were formed, while the more internally diverse Bahnaric branch (dating to about 3,000 B.P.) underwent more extensive internal diversification. By the Iron Age, all of the Austroasiatic branches were more or less in their present-day locations, with most of the diversification within Austroasiatic taking place during the Iron Age. Paul Sidwell (2018) considers the Austroasiatic language family to have rapidly diversified around 4,000 years B.P. during the arrival of rice agriculture in Indochina, but notes that the origin of Proto-Austroasiatic itself is older than that date. The lexicon of Proto-Austroasiatic can be divided into an early and late stratum. The early stratum consists of basic lexicon including body parts, animal names, natural features, and pronouns, while the names of cultural items (agriculture terms and words for cultural artifacts, which are reconstructible in Proto-Austroasiatic) form part of the later stratum. Roger Blench (2017) suggests that vocabulary related to aquatic subsistence strategies (such as boats, waterways, river fauna, and fish capture techniques) can be reconstructed for Proto-Austroasiatic. Blench (2017) finds widespread Austroasiatic roots for 'river, valley', 'boat', 'fish', 'catfish sp.', 'eel', 'prawn', 'shrimp' (Central Austroasiatic), 'crab', 'tortoise', 'turtle', 'otter', 'crocodile', 'heron, fishing bird', and 'fish trap'. Archaeological evidence for the presence of agriculture in northern Indochina (northern Vietnam, Laos, and other nearby areas) dates back to only about 4,000 years ago (2,000 BC), with agriculture ultimately being introduced from further up to the north in the Yangtze valley where it has been dated to 6,000 B.P. Sidwell (2022) proposes that the locus of Proto-Austroasiatic was in the Red River Delta area about 4,000-4,500 years before present, instead of the Middle Mekong as he had previously proposed. Austroasiatic dispersed coastal maritime routes and also upstream through river valleys. Khmuic, Palaungic, and Khasic resulted from a westward dispersal that ultimately came from the Red Valley valley. Based on their current distributions, about half of all Austroasiatic branches (including Nicobaric and Munda) can be traced to coastal maritime dispersals. Hence, this points to a relatively late riverine dispersal of Austroasiatic as compared to Sino-Tibetan, whose speakers had a distinct non-riverine culture. In addition to living an aquatic-based lifestyle, early Austroasiatic speakers would have also had access to livestock, crops, and newer types of watercraft. As early Austroasiatic speakers dispersed rapidly via waterways, they would have encountered speakers of older language families who were already settled in the area, such as Sino-Tibetan. Sidwell (2018) Sidwell (2018) (quoted in Sidwell 2021) gives a more nested classification of Austroasiatic branches as suggested by his computational phylogenetic analysis of Austroasiatic languages using a 200-word list. Many of the tentative groupings are likely linkages. Pakanic and Shompen were not included. Possible extinct branches Roger Blench (2009) also proposes that there might have been other primary branches of Austroasiatic that are now extinct, based on substrate evidence in modern-day languages. Pre-Chamic languages (the languages of coastal Vietnam before the Chamic migrations). Chamic has various Austroasiatic loanwords that cannot be clearly traced to existing Austroasiatic branches (Sidwell 2006, 2007). Larish (1999) also notes that Moklenic languages contain many Austroasiatic loanwords, some of which are similar to the ones found in Chamic. Acehnese substratum (Sidwell 2006). Acehnese has many basic words that are of Austroasiatic origin, suggesting that either Austronesian speakers have absorbed earlier Austroasiatic residents in northern Sumatra, or that words might have been borrowed from Austroasiatic languages in southern Vietnam – or perhaps a combination of both. Sidwell (2006) argues that Acehnese and Chamic had often borrowed Austroasiatic words independently of each other, while some Austroasiatic words can be traced back to Proto-Aceh-Chamic. Sidwell (2006) accepts that Acehnese and Chamic are related, but that they had separated from each other before Chamic had borrowed most of its Austroasiatic lexicon. Bornean substrate languages (Blench 2010). Blench cites Austroasiatic-origin words in modern-day Bornean branches such as Land Dayak (Bidayuh, Dayak Bakatiq, etc.), Dusunic (Central Dusun, Visayan, etc.), Kayan, and Kenyah, noting especially resemblances with Aslian. As further evidence for his proposal, Blench also cites ethnographic evidence such as musical instruments in Borneo shared in common with Austroasiatic-speaking groups in mainland Southeast Asia. Adelaar (1995) has also noticed phonological and lexical similarities between Land Dayak and Aslian. Lepcha substratum ("Rongic"). Many words of Austroasiatic origin have been noticed in Lepcha, suggesting a Sino-Tibetan superstrate laid over an Austroasiatic substrate. Blench (2013) calls this branch "Rongic" based on the Lepcha autonym Róng. Other languages with proposed Austroasiatic substrata are: Jiamao, based on evidence from the register system of Jiamao, a Hlai language (Thurgood 1992). Jiamao is known for its highly aberrant vocabulary in relation to other Hlai languages. Kerinci: van Reijn (1974) notes that Kerinci, a Malayic language of central Sumatra, shares many phonological similarities with Austroasiatic languages, such as sesquisyllabic word structure and vowel inventory. John Peterson (2017) suggests that "pre-Munda" ("proto-" in regular terminology) languages may have once dominated the eastern Indo-Gangetic Plain, and were then absorbed by Indo-Aryan languages at an early date as Indo-Aryan spread east. Peterson notes that eastern Indo-Aryan languages display many morphosyntactic features similar to those of Munda languages, while western Indo-Aryan languages do not. Writing systems Other than Latin-based alphabets, many Austroasiatic languages are written with the Khmer, Thai, Lao, and Burmese alphabets. Vietnamese divergently had an indigenous script based on Chinese logographic writing. This has since been supplanted by the Latin alphabet in the 20th century. The following are examples of past-used alphabets or current alphabets of Austroasiatic languages. Chữ Nôm Khmer alphabet Khom script (used for a short period in the early 20th century for indigenous languages in Laos) Old Mon script Mon script Pahawh Hmong was once used to write Khmu, under the name "Pahawh Khmu" Tai Le (Palaung, Blang) Tai Tham (Blang) Ol Chiki alphabet (Santali alphabet) Mundari Bani (Mundari alphabet) Warang Citi (Ho alphabet) Sorang Sompeng alphabet (Sora alphabet) External relations Austric languages Austroasiatic is an integral part of the controversial Austric hypothesis, which also includes the Austronesian languages, and in some proposals also the Kra–Dai languages and the Hmong–Mien languages. Hmong-Mien Several lexical resemblances are found between the Hmong-Mien and Austroasiatic language families (Ratliff 2010), some of which had earlier been proposed by Haudricourt (1951). This could imply a relation or early language contact along the Yangtze. According to Cai (et al. 2011), Hmong–Mien is at least partially related to Austroasiatic but was heavily influenced by Sino-Tibetan, especially Tibeto-Burman languages. Indo-Aryan languages It is suggested that the Austroasiatic languages have some influence on Indo-Aryan languages including Sanskrit and middle Indo-Aryan languages. Indian linguist Suniti Kumar Chatterji pointed that a specific number of substantives in languages such as Hindi, Punjabi and Bengali were borrowed from Munda languages. Additionally, French linguist Jean Przyluski suggested a similarity between the tales from the Austroasiatic realm and the Indian mythological stories of Matsyagandha (from Mahabharata) and the Nāgas. Austroasiatic migrations and archaeogenetics Mitsuru Sakitani suggests that Haplogroup O1b1, which is common in Austroasiatic people and some other ethnic groups in southern China, and haplogroup O1b2, which is common in today Japanese, Koreans and some Manchu, are the carriers of early rice-agriculturalists from Indochina. Another study suggests that the haplogroup O1b1 is the major Austroasiatic paternal lineage and O1b2 the "para-Austroasiatic" lineage of the Mandchurian, Korean and Yayoi people. A 2021 study by Tagore et al. found that the proto-Austroasiatic-speakers split from an Basal-East Asian source population, native to Mainland Southeast Asia and Northeast India, which also gave rise to other East Asian-related populations, including Northeast Asians and Indigenous peoples of the Americas. The proto-Austroasiatic-speakers can be linked to the Hoabinhian material culture. From Mainland Southeast Asia, the Austroasiatic-speakers expanded into the Indian-subcontinent and Maritime Southeast Asia. There is evidence that later back migration from more northerly East Asian groups (such as Kra-Dai-speakers) merged with indigenous Southeast Asians, contributing to the fragmentation observed among modern day Austroasiatic-speakers. In the Indian subcontinent, Austroasiatic-speakers, specifically Mundari, intermixed with the local population. Furthermore they concluded that their results do not support a genetic relationship between Ancient Southeast Asian hunter-gatherers (Hoabinhians) with Papuan-related groups, as previously suggested by McColl et al. 2018, but that these Ancient Southeast Asians are characterized by Basal-East Asian ancestry. The authors finally concluded that genetics do not necessarily correspond with linguistic identity, pointing to the fragmentation of modern Austroasiatic-speakers. Larena et al. 2021 could reproduce the genetic evidence for the origin of Basal-East Asians in Mainland Southeast Asia, which are estimated to have formed about 50kya years ago, and expanded through multiple migration waves southwards and northwards. Early Austroasiatic-speakers are estimated to have originated from an lineage, which split from Ancestral East Asians between 25,000 to 15,000 years ago, and were among the first wave to replace distinct Australasian-related groups in Insular Southeast Asia. Early Austroasiatic people were found to be best represented by the Mlabri people in modern day Thailand. Proposals for Austroasiatic substratum among later Austronesian languages in Western Indonesia, noteworthy among the Dayak languages, is strengthened by genetic data, suggesting Austroasiatic-speakers were assimilated by Austronesian-speakers. A study in November 2021 (Guo et al.) found that modern East-Eurasians can be modeled from four ancestry components, which descended from a common ancestor in Mainland Southeast Asia, one being the "Ancestral Austroasiatic" component (AAA), which is more prevalent among modern Southeast Asians, and making up the exclusive ancestry among Austroasiatic-speaking Lua and Mlabri people. The early Austroasiatic-speakers are suggested to have been hunter-gatherers but became rice-agriculturalists quite early, spreading from Mainland Southeast Asia northwards to the Yangtze river, westwards into the Indian subcontinent, and southwards into Insular Southeast Asia. Evidence for these migrations are Austroasiatic loanwords related to rice-agriculture found among non-Austroasiatic languages, and the presence of Austroasiatic genetic ancestry. According to a recent genetic study, Sundanese, Javanese, and Balinese, has almost an equal ratio of genetic marker shared between Austronesian and Austroasiatic heritages. Migration into India According to Chaubey et al., "Austro-Asiatic speakers in India today are derived from dispersal from Southeast Asia, followed by extensive sex-specific admixture with local Indian populations." According to Riccio et al., the Munda people are likely descended from Austroasiatic migrants from Southeast Asia. According to Zhang et al., Austroasiatic migrations from Southeast Asia into India took place after the last Glacial maximum, circa 10,000 years ago. Arunkumar et al, suggest Austroasiatic migrations from Southeast Asia occurred into Northeast India 5.2 ± 0.6 kya and into East India 4.3 ± 0.2 kya. Notes References Sources Adams, K. L. (1989).

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table. All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties. Indeed, the alkali metals provide the best example of group trends in properties in the periodic table, with elements exhibiting well-characterised homologous behaviour. This family of elements is also known as the lithium family after its leading element. The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. They can all be cut easily with a knife due to their softness, exposing a shiny surface that tarnishes rapidly in air due to oxidation by atmospheric moisture and oxygen (and in the case of lithium, nitrogen). Because of their high reactivity, they must be stored under oil to prevent reaction with air, and are found naturally only in salts and never as the free elements. Caesium, the fifth alkali metal, is the most reactive of all the metals. All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones. All of the discovered alkali metals occur in nature as their compounds: in order of abundance, sodium is the most abundant, followed by potassium, lithium, rubidium, caesium, and finally francium, which is very rare due to its extremely high radioactivity; francium occurs only in minute traces in nature as an intermediate step in some obscure side branches of the natural decay chains. Experiments have been conducted to attempt the synthesis of ununennium (Uue), which is likely to be the next member of the group; none was successful. However, ununennium may not be an alkali metal due to relativistic effects, which are predicted to have a large influence on the chemical properties of superheavy elements; even if it does turn out to be an alkali metal, it is predicted to have some differences in physical and chemical properties from its lighter homologues. Most alkali metals have many different applications. One of the best-known applications of the pure elements is the use of rubidium and caesium in atomic clocks, of which caesium atomic clocks form the basis of the second. A common application of the compounds of sodium is the sodium-vapour lamp, which emits light very efficiently. Table salt, or sodium chloride, has been used since antiquity. Lithium finds use as a psychiatric medication and as an anode in lithium batteries. Sodium and potassium are also essential elements, having major biological roles as electrolytes, and although the other alkali metals are not essential, they also have various effects on the body, both beneficial and harmful. History Sodium compounds have been known since ancient times; salt (sodium chloride) has been an important commodity in human activities, as testified by the English word salary, referring to salarium, money paid to Roman soldiers for the purchase of salt. While potash has been used since ancient times, it was not understood for most of its history to be a fundamentally different substance from sodium mineral salts. Georg Ernst Stahl obtained experimental evidence which led him to suggest the fundamental difference of sodium and potassium salts in 1702, and Henri-Louis Duhamel du Monceau was able to prove this difference in 1736. The exact chemical composition of potassium and sodium compounds, and the status as chemical element of potassium and sodium, was not known then, and thus Antoine Lavoisier did not include either alkali in his list of chemical elements in 1789. Pure potassium was first isolated in 1807 in England by Humphry Davy, who derived it from caustic potash (KOH, potassium hydroxide) by the use of electrolysis of the molten salt with the newly invented voltaic pile. Previous attempts at electrolysis of the aqueous salt were unsuccessful due to potassium's extreme reactivity. Potassium was the first metal that was isolated by electrolysis. Later that same year, Davy reported extraction of sodium from the similar substance caustic soda (NaOH, lye) by a similar technique, demonstrating the elements, and thus the salts, to be different. Petalite (Li Al Si4O10) was discovered in 1800 by the Brazilian chemist José Bonifácio de Andrada in a mine on the island of Utö, Sweden. However, it was not until 1817 that Johan August Arfwedson, then working in the laboratory of the chemist Jöns Jacob Berzelius, detected the presence of a new element while analysing petalite ore. This new element was noted by him to form compounds similar to those of sodium and potassium, though its carbonate and hydroxide were less soluble in water and more alkaline than the other alkali metals. Berzelius gave the unknown material the name "lithion/lithina", from the Greek word λιθoς (transliterated as lithos, meaning "stone"), to reflect its discovery in a solid mineral, as opposed to potassium, which had been discovered in plant ashes, and sodium, which was known partly for its high abundance in animal blood. He named the metal inside the material "lithium". Lithium, sodium, and potassium were part of the discovery of periodicity, as they are among a series of triads of elements in the same group that were noted by Johann Wolfgang Döbereiner in 1850 as having similar properties. Rubidium and caesium were the first elements to be discovered using the spectroscope, invented in 1859 by Robert Bunsen and Gustav Kirchhoff. The next year, they discovered caesium in the mineral water from Bad Dürkheim, Germany. Their discovery of rubidium came the following year in Heidelberg, Germany, finding it in the mineral lepidolite. The names of rubidium and caesium come from the most prominent lines in their emission spectra: a bright red line for rubidium (from the Latin word rubidus, meaning dark red or bright red), and a sky-blue line for caesium (derived from the Latin word caesius, meaning sky-blue). Around 1865 John Newlands produced a series of papers where he listed the elements in order of increasing atomic weight and similar physical and chemical properties that recurred at intervals of eight; he likened such periodicity to the octaves of music, where notes an octave apart have similar musical functions. His version put all the alkali metals then known (lithium to caesium), as well as copper, silver, and thallium (which show the +1 oxidation state characteristic of the alkali metals), together into a group. His table placed hydrogen with the halogens. After 1869, Dmitri Mendeleev proposed his periodic table placing lithium at the top of a group with sodium, potassium, rubidium, caesium, and thallium. Two years later, Mendeleev revised his table, placing hydrogen in group 1 above lithium, and also moving thallium to the boron group. In this 1871 version, copper, silver, and gold were placed twice, once as part of group IB, and once as part of a "group VIII" encompassing today's groups 8 to 11. After the introduction of the 18-column table, the group IB elements were moved to their current position in the d-block, while alkali metals were left in group IA. Later the group's name was changed to group 1 in 1988. The trivial name "alkali metals" comes from the fact that the hydroxides of the group 1 elements are all strong alkalis when dissolved in water. There were at least four erroneous and incomplete discoveries before Marguerite Perey of the Curie Institute in Paris, France discovered francium in 1939 by purifying a sample of actinium-227, which had been reported to have a decay energy of 220 keV. However, Perey noticed decay particles with an energy level below 80 keV. Perey thought this decay activity might have been caused by a previously unidentified decay product, one that was separated during purification, but emerged again out of the pure actinium-227. Various tests eliminated the possibility of the unknown element being thorium, radium, lead, bismuth, or thallium. The new product exhibited chemical properties of an alkali metal (such as coprecipitating with caesium salts), which led Perey to believe that it was element 87, caused by the alpha decay of actinium-227. Perey then attempted to determine the proportion of beta decay to alpha decay in actinium-227. Her first test put the alpha branching at 0.6%, a figure that she later revised to 1%. The next element below francium (eka-francium) in the periodic table would be ununennium (Uue), element 119. The synthesis of ununennium was first attempted in 1985 by bombarding a target of einsteinium-254 with calcium-48 ions at the superHILAC accelerator at Berkeley, California. No atoms were identified, leading to a limiting yield of 300 nb. + → * → no atoms It is highly unlikely that this reaction will be able to create any atoms of ununennium in the near future, given the extremely difficult task of making sufficient amounts of einsteinium-254, which is favoured for production of ultraheavy elements because of its large mass, relatively long half-life of 270 days, and availability in significant amounts of several micrograms, to make a large enough target to increase the sensitivity of the experiment to the required level; einsteinium has not been found in nature and has only been produced in laboratories, and in quantities smaller than those needed for effective synthesis of superheavy elements. However, given that ununennium is only the first period 8 element on the extended periodic table, it may well be discovered in the near future through other reactions, and indeed an attempt to synthesise it is currently ongoing in Japan. Currently, none of the period 8 elements has been discovered yet, and it is also possible, due to drip instabilities, that only the lower period 8 elements, up to around element 128, are physically possible. No attempts at synthesis have been made for any heavier alkali metals: due to their extremely high atomic number, they would require new, more powerful methods and technology to make. Occurrence In the Solar System The Oddo–Harkins rule holds that elements with even atomic numbers are more common that those with odd atomic numbers, with the exception of hydrogen. This rule argues that elements with odd atomic numbers have one unpaired proton and are more likely to capture another, thus increasing their atomic number. In elements with even atomic numbers, protons are paired, with each member of the pair offsetting the spin of the other, enhancing stability. All the alkali metals have odd atomic numbers and they are not as common as the elements with even atomic numbers adjacent to them (the noble gases and the alkaline earth metals) in the Solar System. The heavier alkali metals are also less abundant than the lighter ones as the alkali metals from rubidium onward can only be synthesised in supernovae and not in stellar nucleosynthesis. Lithium is also much less abundant than sodium and potassium as it is poorly synthesised in both Big Bang nucleosynthesis and in stars: the Big Bang could only produce trace quantities of lithium, beryllium and boron due to the absence of a stable nucleus with 5 or 8 nucleons, and stellar nucleosynthesis could only pass this bottleneck by the triple-alpha process, fusing three helium nuclei to form carbon, and skipping over those three elements. On Earth The Earth formed from the same cloud of matter that formed the Sun, but the planets acquired different compositions during the formation and evolution of the solar system. In turn, the natural history of the Earth caused parts of this planet to have differing concentrations of the elements. The mass of the Earth is approximately 5.98 kg. It is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%); with the remaining 1.2% consisting of trace amounts of other elements. Due to planetary differentiation, the core region is believed to be primarily composed of iron (88.8%), with smaller amounts of nickel (5.8%), sulfur (4.5%), and less than 1% trace elements. The alkali metals, due to their high reactivity, do not occur naturally in pure form in nature. They are lithophiles and therefore remain close to the Earth's surface because they combine readily with oxygen and so associate strongly with silica, forming relatively low-density minerals that do not sink down into the Earth's core. Potassium, rubidium and caesium are also incompatible elements due to their large ionic radii. Sodium and potassium are very abundant in earth, both being among the ten most common elements in Earth's crust; sodium makes up approximately 2.6% of the Earth's crust measured by weight, making it the sixth most abundant element overall and the most abundant alkali metal. Potassium makes up approximately 1.5% of the Earth's crust and is the seventh most abundant element. Sodium is found in many different minerals, of which the most common is ordinary salt (sodium chloride), which occurs in vast quantities dissolved in seawater. Other solid deposits include halite, amphibole, cryolite, nitratine, and zeolite. Many of these solid deposits occur as a result of ancient seas evaporating, which still occurs now in places such as Utah's Great Salt Lake and the Dead Sea. Despite their near-equal abundance in Earth's crust, sodium is far more common than potassium in the ocean, both because potassium's larger size makes its salts less soluble, and because potassium is bound by silicates in soil and what potassium leaches is absorbed far more readily by plant life than sodium. Despite its chemical similarity, lithium typically does not occur together with sodium or potassium due to its smaller size. Due to its relatively low reactivity, it can be found in seawater in large amounts; it is estimated that seawater is approximately 0.14 to 0.25 parts per million (ppm) or 25 micromolar. Its diagonal relationship with magnesium often allows it to replace magnesium in ferromagnesium minerals, where its crustal concentration is about 18 ppm, comparable to that of gallium and niobium. Commercially, the most important lithium mineral is spodumene, which occurs in large deposits worldwide. Rubidium is approximately as abundant as zinc and more abundant than copper. It occurs naturally in the minerals leucite, pollucite, carnallite, zinnwaldite, and lepidolite, although none of these contain only rubidium and no other alkali metals. Caesium is more abundant than some commonly known elements, such as antimony, cadmium, tin, and tungsten, but is much less abundant than rubidium. Francium-223, the only naturally occurring isotope of francium, is the product of the alpha decay of actinium-227 and can be found in trace amounts in uranium minerals. In a given sample of uranium, there is estimated to be only one francium atom for every 1018 uranium atoms. It has been calculated that there are at most 30 grams of francium in the earth's crust at any time, due to its extremely short half-life of 22 minutes. Properties Physical and chemical The physical and chemical properties of the alkali metals can be readily explained by their having an ns1 valence electron configuration, which results in weak metallic bonding. Hence, all the alkali metals are soft and have low densities, melting and boiling points, as well as heats of sublimation, vaporisation, and dissociation. They all crystallise in the body-centered cubic crystal structure, and have distinctive flame colours because their outer s electron is very easily excited. The ns1 configuration also results in the alkali metals having very large atomic and ionic radii, as well as very high thermal and electrical conductivity. Their chemistry is dominated by the loss of their lone valence electron in the outermost s-orbital to form the +1 oxidation state, due to the ease of ionising this electron and the very high second ionisation energy. Most of the chemistry has been observed only for the first five members of the group. The chemistry of francium is not well established due to its extreme radioactivity; thus, the presentation of its properties here is limited. What little is known about francium shows that it is very close in behaviour to caesium, as expected. The physical properties of francium are even sketchier because the bulk element has never been observed; hence any data that may be found in the literature are certainly speculative extrapolations. The alkali metals are more similar to each other than the elements in any other group are to each other. Indeed, the similarity is so great that it is quite difficult to separate potassium, rubidium, and caesium, due to their similar ionic radii; lithium and sodium are more distinct. For instance, when moving down the table, all known alkali metals show increasing atomic radius, decreasing electronegativity, increasing reactivity, and decreasing melting and boiling points as well as heats of fusion and vaporisation. In general, their densities increase when moving down the table, with the exception that potassium is less dense than sodium. One of the very few properties of the alkali metals that does not display a very smooth trend is their reduction potentials: lithium's value is anomalous, being more negative than the others. This is because the Li+ ion has a very high hydration energy in the gas phase: though the lithium ion disrupts the structure of water significantly, causing a higher change in entropy, this high hydration energy is enough to make the reduction potentials indicate it as being the most electropositive alkali metal, despite the difficulty of ionising it in the gas phase. The stable alkali metals are all silver-coloured metals except for caesium, which has a pale golden tint: it is one of only three metals that are clearly coloured (the other two being copper and gold). Additionally, the heavy alkaline earth metals calcium, strontium, and barium, as well as the divalent lanthanides europium and ytterbium, are pale yellow, though the colour is much less prominent than it is for caesium. Their lustre tarnishes rapidly in air due to oxidation. They all crystallise in the body-centered cubic crystal structure, and have distinctive flame colours because their outer s electron is very easily excited. Indeed, these flame test colours are the most common way of identifying them since all their salts with common ions are soluble. All the alkali metals are highly reactive and are never found in elemental forms in nature. Because of this, they are usually stored in mineral oil or kerosene (paraffin oil). They react aggressively with the halogens to form the alkali metal halides, which are white ionic crystalline compounds that are all soluble in water except lithium fluoride (Li F). The alkali metals also react with water to form strongly alkaline hydroxides and thus should be handled with great care. The heavier alkali metals react more vigorously than the lighter ones; for example, when dropped into water, caesium produces a larger explosion than potassium if the same number of moles of each metal is used. The alkali metals have the lowest first ionisation energies in their respective periods of the periodic table because of their low effective nuclear charge and the ability to attain a noble gas configuration by losing just one electron. Not only do the alkali metals react with water, but also with proton donors like alcohols and phenols, gaseous ammonia, and alkynes, the last demonstrating the phenomenal degree of their reactivity. Their great power as reducing agents makes them very useful in liberating other metals from their oxides or halides. The second ionisation energy of all of the alkali metals is very high as it is in a full shell that is also closer to the nucleus; thus, they almost always lose a single electron, forming cations. The alkalides are an exception: they are unstable compounds which contain alkali metals in a −1 oxidation state, which is very unusual as before the discovery of the alkalides, the alkali metals were not expected to be able to form anions and were thought to be able to appear in salts only as cations. The alkalide anions have filled s-subshells, which gives them enough stability to exist. All the stable alkali metals except lithium are known to be able to form alkalides, and the alkalides have much theoretical interest due to their unusual stoichiometry and low ionisation potentials. Alkalides are chemically similar to the electrides, which are salts with trapped electrons acting as anions. A particularly striking example of an alkalide is "inverse sodium hydride", H+Na− (both ions being complexed), as opposed to the usual sodium hydride, Na+H−: it is unstable in isolation, due to its high energy resulting from the displacement of two electrons from hydrogen to sodium, although several derivatives are predicted to be metastable or stable. In aqueous solution, the alkali metal ions form aqua ions of the formula [M(H2O)n]+, where n is the solvation number. Their coordination numbers and shapes agree well with those expected from their ionic radii. In aqueous solution the water molecules directly attached to the metal ion are said to belong to the first coordination sphere, also known as the first, or primary, solvation shell. The bond between a water molecule and the metal ion is a dative covalent bond, with the oxygen atom donating both electrons to the bond. Each coordinated water molecule may be attached by hydrogen bonds to other water molecules. The latter are said to reside in the second coordination sphere. However, for the alkali metal cations, the second coordination sphere is not well-defined as the +1 charge on the cation is not high enough to polarise the water molecules in the primary solvation shell enough for them to form strong hydrogen bonds with those in the second coordination sphere, producing a more stable entity. The solvation number for Li+ has been experimentally determined to be 4, forming the tetrahedral [Li(H2O)4]+: while solvation numbers of 3 to 6 have been found for lithium aqua ions, solvation numbers less than 4 may be the result of the formation of contact ion pairs, and the higher solvation numbers may be interpreted in terms of water molecules that approach [Li(H2O)4]+ through a face of the tetrahedron, though molecular dynamic simulations may indicate the existence of an octahedral hexaaqua ion. There are also probably six water molecules in the primary solvation sphere of the sodium ion, forming the octahedral [Na(H2O)6]+ ion. While it was previously thought that the heavier alkali metals also formed octahedral hexaaqua ions, it has since been found that potassium and rubidium probably form the [K(H2O)8]+ and [Rb(H2O)8]+ ions, which have the square antiprismatic structure, and that caesium forms the 12-coordinate [Cs(H2O)12]+ ion. Lithium The chemistry of lithium shows several differences from that of the rest of the group as the small Li+ cation polarises anions and gives its compounds a more covalent character. Lithium and magnesium have a diagonal relationship due to their similar atomic radii, so that they show some similarities. For example, lithium forms a stable nitride, a property common among all the alkaline earth metals (magnesium's group) but unique among the alkali metals. In addition, among their respective groups, only lithium and magnesium form organometallic compounds with significant covalent character (e.g. LiMe and MgMe2). Lithium fluoride is the only alkali metal halide that is poorly soluble in water, and lithium hydroxide is the only alkali metal hydroxide that is not deliquescent. Conversely, lithium perchlorate and other lithium salts with large anions that cannot be polarised are much more stable than the analogous compounds of the other alkali metals, probably because Li+ has a high solvation energy. This effect also means that most simple lithium salts are commonly encountered in hydrated form, because the anhydrous forms are extremely hygroscopic: this allows salts like lithium chloride and lithium bromide to be used in dehumidifiers and air-conditioners. Francium Francium is also predicted to show some differences due to its high atomic weight, causing its electrons to travel at considerable fractions of the speed of light and thus making relativistic effects more prominent. In contrast to the trend of decreasing electronegativities and ionisation energies of the alkali metals, francium's electronegativity and ionisation energy are predicted to be higher than caesium's due to the relativistic stabilisation of the 7s electrons; also, its atomic radius is expected to be abnormally low. Thus, contrary to expectation, caesium is the most reactive of the alkali metals, not francium. All known physical properties of francium also deviate from the clear trends going from lithium to caesium, such as the first ionisation energy, electron affinity, and anion polarisability, though due to the paucity of known data about francium many sources give extrapolated values, ignoring that relativistic effects make the trend from lithium to caesium become inapplicable at francium. Some of the few properties of francium that have been predicted taking relativity into account are the electron affinity (47.2 kJ/mol) and the enthalpy of dissociation of the Fr2 molecule (42.1 kJ/mol). The CsFr molecule is polarised as Cs+Fr−, showing that the 7s subshell of francium is much more strongly affected by relativistic effects than the 6s subshell of caesium. Additionally, francium superoxide (FrO2) is expected to have significant covalent character, unlike the other alkali metal superoxides, because of bonding contributions from the 6p electrons of francium. Nuclear All the alkali metals have odd atomic numbers; hence, their isotopes must be either odd–odd (both proton and neutron number are odd) or odd–even (proton number is odd, but neutron number is even). Odd–odd nuclei have even mass numbers, whereas odd–even nuclei have odd mass numbers. Odd–odd primordial nuclides are rare because most odd–odd nuclei are highly unstable with respect to beta decay, because the decay products are even–even, and are therefore more strongly bound, due to nuclear pairing effects. Due to the great rarity of odd–odd nuclei, almost all the primordial isotopes of the alkali metals are odd–even (the exceptions being the light stable isotope lithium-6 and the long-lived radioisotope potassium-40). For a given odd mass number, there can be only a single beta-stable nuclide, since there is not a difference in binding energy between even–odd and odd–even comparable to that between even–even and odd–odd, leaving other nuclides of the same mass number (isobars) free to beta decay toward the lowest-mass nuclide. An effect of the instability of an odd number of either type of nucleons is that odd-numbered elements, such as the alkali metals, tend to have fewer stable isotopes than even-numbered elements. Of the 26 monoisotopic elements that have only a single stable isotope, all but one have an odd atomic number and all but one also have an even number of neutrons. Beryllium is the single exception to both rules, due to its low atomic number. All of the alkali metals except lithium and caesium have at least one naturally occurring radioisotope: sodium-22 and sodium-24 are trace radioisotopes produced cosmogenically, potassium-40 and rubidium-87 have very long half-lives and thus occur naturally, and all isotopes of francium are radioactive. Caesium was also thought to be radioactive in the early 20th century, although it has no naturally occurring radioisotopes. (Francium had not been discovered yet at that time.) The natural long-lived radioisotope of potassium, potassium-40, makes up about 0.012% of natural potassium, and thus natural potassium is weakly radioactive. This natural radioactivity became a basis for a mistaken claim of the discovery for element 87 (the next alkali metal after caesium) in 1925. Natural rubidium is similarly slightly radioactive, with 27.83% being the long-lived radioisotope rubidium-87. Caesium-137, with a half-life of 30.17 years, is one of the two principal medium-lived fission products, along with strontium-90, which are responsible for most of the radioactivity of spent nuclear fuel after several years of cooling, up to several hundred years after use. It constitutes most of the radioactivity still left from the Chernobyl accident. Caesium-137 undergoes high-energy beta decay and eventually becomes stable barium-137. It is a strong emitter of gamma radiation. Caesium-137 has a very low rate of neutron capture and cannot be feasibly disposed of in this way, but must be allowed to decay. Caesium-137 has been used as a tracer in hydrologic studies, analogous to the use of tritium. Small amounts of caesium-134 and caesium-137 were released into the environment during nearly all nuclear weapon tests and some nuclear accidents, most notably the Goiânia accident and the Chernobyl disaster. As of 2005, caesium-137 is the principal source of radiation in the zone of alienation around the Chernobyl nuclear power plant. Its chemical properties as one of the alkali metals make it one of most problematic of the short-to-medium-lifetime fission products because it easily moves and spreads in nature due to the high water solubility of its salts, and is taken up by the body, which mistakes it for its essential congeners sodium and potassium. Periodic trends The alkali metals are more similar to each other than the elements in any other group are to each other. For instance, when moving down the table, all known alkali metals show increasing atomic radius, decreasing electronegativity, increasing reactivity, and decreasing melting and boiling points as well as heats of fusion and vaporisation. In general, their densities increase when moving down the table, with the exception that potassium is less dense than sodium. Atomic and ionic radii The atomic radii of the alkali metals increase going down the group. Because of the shielding effect, when an atom has more than one electron shell, each electron feels electric repulsion from the other electrons as well as electric attraction from the nucleus. In the alkali metals, the outermost electron only feels a net charge of +1, as some of the nuclear charge (which is equal to the atomic number) is cancelled by the inner electrons; the number of inner electrons of an alkali metal is always one less than the nuclear charge. Therefore, the only factor which affects the atomic radius of the alkali metals is the number of electron shells. Since this number increases down the group, the atomic radius must also increase down the group. The ionic radii of the alkali metals are much smaller than their atomic radii. This is because the outermost electron of the alkali metals is in a different electron shell than the inner electrons, and thus when it is removed the resulting atom has one fewer electron shell and is smaller. Additionally, the effective nuclear charge has increased, and thus the electrons are attracted more strongly towards the nucleus and the ionic radius decreases. First ionisation energy The first ionisation energy of an element or molecule is the energy required to move the most loosely held electron from one mole of gaseous atoms of the element or molecules to form one mole of gaseous ions with electric charge +1. The factors affecting the first ionisation energy are the nuclear charge, the amount of shielding by the inner electrons and the distance from the most loosely held electron from the nucleus, which is always an outer electron in main group elements. The first two factors change the effective nuclear charge the most loosely held electron feels. Since the outermost electron of alkali metals always feels the same effective nuclear charge (+1), the only factor which affects the first ionisation energy is the distance from the outermost electron to the nucleus. Since this distance increases down the group, the outermost electron feels less attraction from the nucleus and thus the first ionisation energy decreases. (This trend is broken in francium due to the relativistic stabilisation and contraction of the 7s orbital, bringing francium's valence electron closer to the nucleus than would be expected from non-relativistic calculations. This makes francium's outermost electron feel more attraction from the nucleus, increasing its first ionisation energy slightly beyond that of caesium.) The second ionisation energy of the alkali metals is much higher than the first as the second-most loosely held electron is part of a fully filled electron shell and is thus difficult to remove. Reactivity The reactivities of the alkali metals increase going down the group. This is the result of a combination of two factors: the first ionisation energies and atomisation energies of the alkali metals. Because the first ionisation energy of the alkali metals decreases down the group, it is easier for the outermost electron to be removed from the atom and participate in chemical reactions, thus increasing reactivity down the group. The atomisation energy measures the strength of the metallic bond of an element, which falls down the group as the atoms increase in radius and thus the metallic bond must increase in length, making the delocalised electrons further away from the attraction of the nuclei of the heavier alkali metals. Adding the atomisation and first ionisation energies gives a quantity closely related to (but not equal to) the activation energy of the reaction of an alkali metal with another substance. This quantity decreases going down the group, and so does the activation energy; thus, chemical reactions can occur faster and the reactivity increases down the group. Electronegativity Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. If the bond between sodium and chlorine in sodium chloride were covalent, the pair of shared electrons would be attracted to the chlorine because the effective nuclear charge on the outer electrons is +7 in chlorine but is only +1 in sodium. The electron pair is attracted so close to the chlorine atom that they are practically transferred to the chlorine atom (an ionic bond). However, if the sodium atom was replaced by a lithium atom, the electrons will not be attracted as close to the chlorine atom as before because the lithium atom is smaller, making the electron pair more strongly attracted to the closer effective nuclear charge from lithium. Hence, the larger alkali metal atoms (further down the group) will be less electronegative as the bonding pair is less strongly attracted towards them. As mentioned previously, francium is expected to be an exception. Because of the higher electronegativity of lithium, some of its compounds have a more covalent character. For example, lithium iodide (Li I) will dissolve in organic solvents, a property of most covalent compounds. Lithium fluoride (LiF) is the only alkali halide that is not soluble in water, and lithium hydroxide (LiOH) is the only alkali metal hydroxide that is not deliquescent. Melting and boiling points The melting point of a substance is the point where it changes state from solid to liquid while the boiling point of a substance (in liquid state) is the point where the vapour pressure of the liquid equals the environmental pressure surrounding the liquid and all the liquid changes state to gas. As a metal is heated to its melting point, the metallic bonds keeping the atoms in place weaken so that the atoms can move around, and the metallic bonds eventually break completely at the metal's boiling point. Therefore, the falling melting and boiling points of the alkali metals indicate that the strength of the metallic bonds of the alkali metals decreases down the group. This is because metal atoms are held together by the electromagnetic attraction from the positive ions to the delocalised electrons. As the atoms increase in size going down the group (because their atomic radius increases), the nuclei of the ions move further away from the delocalised electrons and hence the metallic bond becomes weaker so that the metal can more easily melt and boil, thus lowering the melting and boiling points. (The increased nuclear charge is not a relevant factor due to the shielding effect.) Density The alkali metals all have the same crystal structure (body-centred cubic) and thus the only relevant factors are the number of atoms that can fit into a certain volume and the mass of one of the atoms, since density is defined as mass per unit volume. The first factor depends on the volume of the atom and thus the atomic radius, which increases going down the group; thus, the volume of an alkali metal atom increases going down the group. The mass of an alkali metal atom also increases going down the group. Thus, the trend for the densities of the alkali metals depends on their atomic weights and atomic radii; if figures for these two factors are known, the ratios between the densities of the alkali metals can then be calculated. The resultant trend is that the densities of the alkali metals increase down the table, with an exception at potassium. Due to having the lowest atomic weight and the largest atomic radius of all the elements in their periods, the alkali metals are the least dense metals in the periodic table. Lithium, sodium, and potassium are the only three metals in the periodic table that are less dense than water: in fact, lithium is the least dense known solid at room temperature. Compounds The alkali metals form complete series of compounds with all usually encountered anions, which well illustrate group trends. These compounds can be described as involving the alkali metals losing electrons to acceptor species and forming monopositive ions. This description is most accurate for alkali halides and becomes less and less accurate as cationic and anionic charge increase, and as the anion becomes larger and more polarisable. For instance, ionic bonding gives way to metallic bonding along the series NaCl, Na2O, Na2S, Na3P, Na3As, Na3Sb, Na3Bi, Na. Hydroxides All the alkali metals react vigorously or explosively with cold water, producing an aqueous solution of a strongly basic alkali metal hydroxide and releasing hydrogen gas. This reaction becomes more vigorous going down the group: lithium reacts steadily with effervescence, but sodium and potassium can ignite, and rubidium and caesium sink in water and generate hydrogen gas so rapidly that shock waves form in the water that may shatter glass containers. When an alkali metal is dropped into water, it produces an explosion, of which there are two separate stages. The metal reacts with the water first, breaking the hydrogen bonds in the water and producing hydrogen gas; this takes place faster for the more reactive heavier alkali metals. Second, the heat generated by the first part of the reaction often ignites the hydrogen gas, causing it to burn explosively into the surrounding air. This secondary hydrogen gas explosion produces the visible flame above the bowl of water, lake or other body of water, not the initial reaction of the metal with water (which tends to happen mostly under water). The alkali metal hydroxides are the most basic known hydroxides. Recent research has suggested that the explosive behavior of alkali metals in water is driven by a Coulomb explosion rather than solely by rapid generation of hydrogen itself. All alkali metals melt as a part of the reaction with water. Water molecules ionise the bare metallic surface of the liquid metal, leaving a positively charged metal surface and negatively charged water ions. The attraction between the charged metal and water ions will rapidly increase the surface area, causing an exponential increase of ionisation. When the repulsive forces within the liquid metal surface exceeds the forces of the surface tension, it vigorously explodes. The hydroxides themselves are the most basic hydroxides known, reacting with acids to give salts and with alcohols to give oligomeric alkoxides. They easily react with carbon dioxide to form carbonates or bicarbonates, or with hydrogen sulfide to form sulfides or bisulfides, and may be used to separate thiols from petroleum. They react with amphoteric oxides: for example, the oxides of aluminium, zinc, tin, and lead react with the alkali metal hydroxides to give aluminates, zincates, stannates, and plumbates. Silicon dioxide is acidic, and thus the alkali metal hydroxides can also attack silicate glass. Intermetallic compounds The alkali metals form many intermetallic compounds with each other and the elements from groups 2 to 13 in the periodic table of varying stoichiometries, such as the sodium amalgams with mercury, including Na5Hg8 and Na3Hg. Some of these have ionic characteristics: taking the alloys with gold, the most electronegative of metals, as an example, NaAu and KAu are metallic, but RbAu and CsAu are semiconductors. NaK is an alloy of sodium and potassium that is very useful because it is liquid at room temperature, although precautions must be taken due to its extreme reactivity towards water and air. The eutectic mixture melts at −12.6 °C. An alloy of 41% caesium, 47% sodium, and 12% potassium has the lowest known melting point of any metal or alloy, −78 °C. Compounds with the group 13 elements The intermetallic compounds of the alkali metals with the heavier group 13 elements (aluminium, gallium, indium, and thallium), such as NaTl, are poor conductors or semiconductors, unlike the normal alloys with the preceding elements, implying that the alkali metal involved has lost an electron to the Zintl anions involved. Nevertheless, while the elements in group 14 and beyond tend to form discrete anionic clusters, group 13 elements tend to form polymeric ions with the alkali metal cations located between the giant ionic lattice. For example, NaTl consists of a polymeric anion (—Tl−—)n with a covalent diamond cubic structure with Na+ ions located between the anionic lattice. The larger alkali metals cannot fit similarly into an anionic lattice and tend to force the heavier group 13 elements to form anionic clusters. Boron is a special case, being the only nonmetal in group 13. The alkali metal borides tend to be boron-rich, involving appreciable boron–boron bonding involving deltahedral structures, and are thermally unstable due to the alkali metals having a very high vapour pressure at elevated temperatures. This makes direct synthesis problematic because the alkali metals do not react with boron below 700 °C, and thus this must be accomplished in sealed containers with the alkali metal in excess. Furthermore, exceptionally in this group, reactivity with boron decreases down the group: lithium reacts completely at 700 °C, but sodium at 900 °C and potassium not until 1200 °C, and the reaction is instantaneous for lithium but takes hours for potassium. Rubidium and caesium borides have not even been characterised. Various phases are known, such as LiB10, NaB6, NaB15, and KB6. Under high pressure the boron–boron bonding in the lithium borides changes from following Wade's rules to forming Zintl anions like the rest of group 13. Compounds with the group 14 elements Lithium and sodium react with carbon to form acetylides, Li2C2 and Na2C2, which can also be obtained by reaction of the metal with acetylene. Potassium, rubidium, and caesium react with graphite; their atoms are intercalated between the hexagonal graphite layers, forming graphite intercalation compounds of formulae MC60 (dark grey, almost black), MC48 (dark grey, almost black), MC36 (blue), MC24 (steel blue), and MC8 (bronze) (M = K, Rb, or Cs). These compounds are over 200 times more electrically conductive than pure graphite, suggesting that the valence electron of the alkali metal is transferred to the graphite layers (e.g. ). Upon heating of KC8, the elimination of potassium atoms results in the conversion in sequence to KC24, KC36, KC48 and finally KC60. KC8 is a very strong reducing agent and is pyrophoric and explodes on contact with water. While the larger alkali metals (K, Rb, and Cs) initially form MC8, the smaller ones initially form MC6, and indeed they require reaction of the metals with graphite at high temperatures around 500 °C to form. Apart from this, the alkali metals are such strong reducing agents that they can even reduce buckminsterfullerene to produce solid fullerides MnC60; sodium, potassium, rubidium, and caesium can form fullerides where n = 2, 3, 4, or 6, and rubidium and caesium additionally can achieve n = 1. When the alkali metals react with the heavier elements in the carbon group (silicon, germanium, tin, and lead), ionic substances with cage-like structures are formed, such as the silicides M4Si4 (M = K, Rb, or Cs), which contains M+ and tetrahedral ions. The chemistry of alkali metal germanides, involving the germanide ion Ge4− and other cluster (Zintl) ions such as , , , and [(Ge9)2]6−, is largely analogous to that of the corresponding silicides. Alkali metal stannides are mostly ionic, sometimes with the stannide ion (Sn4−), and sometimes with more complex Zintl ions such as , which appears in tetrapotassium nonastannide (K4Sn9). The monatomic plumbide ion (Pb4−) is unknown, and indeed its formation is predicted to be energetically unfavourable; alkali metal plumbides have complex Zintl ions, such as . These alkali metal germanides, stannides, and plumbides may be produced by reducing germanium, tin, and lead with sodium metal in liquid ammonia. Nitrides and pnictides Lithium, the lightest of the alkali metals, is the only alkali metal which reacts with nitrogen at standard conditions, and its nitride is the only stable alkali metal nitride. Nitrogen is an unreactive gas because breaking the strong triple bond in the dinitrogen molecule (N2) requires a lot of energy. The formation of an alkali metal nitride would consume the ionisation energy of the alkali metal (forming M+ ions), the energy required to break the triple bond in N2 and the formation of N3− ions, and all the energy released from the formation of an alkali metal nitride is from the lattice energy of the alkali metal nitride. The lattice energy is maximised with small, highly charged ions; the alkali metals do not form highly charged ions, only forming ions with a charge of +1, so only lithium, the smallest alkali metal, can release enough lattice energy to make the reaction with nitrogen exothermic, forming lithium nitride. The reactions of the other alkali metals with nitrogen would not release enough lattice energy and would thus be endothermic, so they do not form nitrides at standard conditions. Sodium nitride (Na3N) and potassium nitride (K3N), while existing, are extremely unstable, being prone to decomposing back into their constituent elements, and cannot be produced by reacting the elements with each other at standard conditions. Steric hindrance forbids the existence of rubidium or caesium nitride. However, sodium and potassium form colourless azide salts involving the linear anion; due to the large size of the alkali metal cations, they are thermally stable enough to be able to melt before decomposing. All the alkali metals react readily with phosphorus and arsenic to form phosphides and arsenides with the formula M3Pn (where M represents an alkali metal and Pn represents a pnictogen – phosphorus, arsenic, antimony, or bismuth). This is due to the greater size of the P3− and As3− ions, so that less lattice energy needs to be released for the salts to form. These are not the only phosphides and arsenides of the alkali metals: for example, potassium has nine different known phosphides, with formulae K3P, K4P3, K5P4, KP, K4P6, K3P7, K3P11, KP10.3, and KP15. While most metals form arsenides, only the alkali and alkaline earth metals form mostly ionic arsenides. The structure of Na3As is complex with unusually short Na–Na distances of 328–330 pm which are shorter than in sodium metal, and this indicates that even with these electropositive metals the bonding cannot be straightforwardly ionic. Other alkali metal arsenides not conforming to the formula M3As are known, such as LiAs, which has a metallic lustre and electrical conductivity indicating the presence of some metallic bonding. The antimonides are unstable and reactive as the Sb3− ion is a strong reducing agent; reaction of them with acids form the toxic and unstable gas stibine (SbH3). Indeed, they have some metallic properties, and the alkali metal antimonides of stoichiometry MSb involve antimony atoms bonded in a spiral Zintl structure. Bismuthides are not even wholly ionic; they are intermetallic compounds containing partially metallic and partially ionic bonds. Oxides and chalcogenides All the alkali metals react vigorously with oxygen at standard conditions. They form various types of oxides, such as simple oxides (containing the O2− ion), peroxides (containing the ion, where there is a single bond between the two oxygen atoms), superoxides (containing the ion), and many others. Lithium burns in air to form lithium oxide, but sodium reacts with oxygen to form a mixture of sodium oxide and sodium peroxide. Potassium forms a mixture of potassium peroxide and potassium superoxide, while rubidium and caesium form the superoxide exclusively. Their reactivity increases going down the group: while lithium, sodium and potassium merely burn in air, rubidium and caesium are pyrophoric (spontaneously catch fire in air). The smaller alkali metals tend to polarise the larger anions (the peroxide and superoxide) due to their small size. This attracts the electrons in the more complex anions towards one of its constituent oxygen atoms, forming an oxide ion and an oxygen atom. This causes lithium to form the oxide exclusively on reaction with oxygen at room temperature. This effect becomes drastically weaker for the larger sodium and potassium, allowing them to form the less stable peroxides. Rubidium and caesium, at the bottom of the group, are so large that even the least stable superoxides can form. Because the superoxide releases the most energy when formed, the superoxide is preferentially formed for the larger alkali metals where the more complex anions are not polarised. (The oxides and peroxides for these alkali metals do exist, but do not form upon direct reaction of the metal with oxygen at standard conditions.) In addition, the small size of the Li+ and O2− ions contributes to their forming a stable ionic lattice structure. Under controlled conditions, however, all the alkali metals, with the exception of francium, are known to form their oxides, peroxides, and superoxides. The alkali metal peroxides and superoxides are powerful oxidising agents. Sodium peroxide and potassium superoxide react with carbon dioxide to form the alkali metal carbonate and oxygen gas, which allows them to be used in submarine air purifiers; the presence of water vapour, naturally present in breath, makes the removal of carbon dioxide by potassium superoxide even more efficient. All the stable alkali metals except lithium can form red ozonides (MO3) through low-temperature reaction of the powdered anhydrous hydroxide with ozone: the ozonides may be then extracted using liquid ammonia. They slowly decompose at standard conditions to the superoxides and oxygen, and hydrolyse immediately to the hydroxides when in contact with water. Potassium, rubidium, and caesium also form sesquioxides M2O3, which may be better considered peroxide disuperoxides, . Rubidium and caesium can form a great variety of suboxides with the metals in formal oxidation states below +1. Rubidium can form Rb6O and Rb9O2 (copper-coloured) upon oxidation in air, while caesium forms an immense variety of oxides, such as the ozonide CsO3 and several brightly coloured suboxides, such as Cs7O (bronze), Cs4O (red-violet), Cs11O3 (violet), Cs3O (dark green), CsO, Cs3O2, as well as Cs7O2. The last of these may be heated under vacuum to generate Cs2O. The alkali metals can also react analogously with the heavier chalcogens (sulfur, selenium, tellurium, and polonium), and all the alkali metal chalcogenides are known (with the exception of francium's). Reaction with an excess of the chalcogen can similarly result in lower chalcogenides, with chalcogen ions containing chains of the chalcogen atoms in question. For example, sodium can react with sulfur to form the sulfide (Na2S) and various polysulfides with the formula Na2Sx (x from 2 to 6), containing the ions. Due to the basicity of the Se2− and Te2− ions, the alkali metal selenides and tellurides are alkaline in solution; when reacted directly with selenium and tellurium, alkali metal polyselenides and polytellurides are formed along with the selenides and tellurides with the and ions. They may be obtained directly from the elements in liquid ammonia or when air is not present, and are colourless, water-soluble compounds that air oxidises quickly back to selenium or tellurium. The alkali metal polonides are all ionic compounds containing the Po2− ion; they are very chemically stable and can be produced by direct reaction of the elements at around 300–400 °C. Halides, hydrides, and pseudohalides The alkali metals are among the most electropositive elements on the periodic table and thus tend to bond ionically to the most electronegative elements on the periodic table, the halogens (fluorine, chlorine, bromine, iodine, and astatine), forming salts known as the alkali metal halides. The reaction is very vigorous and can sometimes result in explosions. All twenty stable alkali metal halides are known; the unstable ones are not known, with the exception of sodium astatide, because of the great instability and rarity of astatine and francium. The most well-known of the twenty is certainly sodium chloride, otherwise known as common salt. All of the stable alkali metal halides have the formula MX where M is an alkali metal and X is a halogen. They are all white ionic crystalline solids that have high melting points. All the alkali metal halides are soluble in water except for lithium fluoride (LiF), which is insoluble in water due to its very high lattice enthalpy. The high lattice enthalpy of lithium fluoride is due to the small sizes of the Li+ and F− ions, causing the electrostatic interactions between them to be strong: a similar effect occurs for magnesium fluoride, consistent with the diagonal relationship between lithium and magnesium. The alkali metals also react similarly with hydrogen to form ionic alkali metal hydrides, where the hydride anion acts as a pseudohalide: these are often used as reducing agents, producing hydrides, complex metal hydrides, or hydrogen gas. Other pseudohalides are also known, notably the cyanides. These are isostructural to the respective halides except for lithium cyanide, indicating that the cyanide ions may rotate freely. Ternary alkali metal halide oxides, such as Na3ClO, K3BrO (yellow), Na4Br2O, Na4I2O, and K4Br2O, are also known. The polyhalides are rather unstable, although those of rubidium and caesium are greatly stabilised by the feeble polarising power of these extremely large cations. Coordination complexes Alkali metal cations do not usually form coordination complexes with simple Lewis bases due to their low charge of just +1 and their relatively large size; thus the Li+ ion forms most complexes and the heavier alkali metal ions form less and less (though exceptions occur for weak complexes). Lithium in particular has a very rich coordination chemistry in which it exhibits coordination numbers from 1 to 12, although octahedral hexacoordination is its preferred mode. In aqueous solution, the alkali metal ions exist as octahedral hexahydrate complexes ([M(H2O)6)]+), with the exception of the lithium ion, which due to its small size forms tetrahedral tetrahydrate complexes ([Li(H2O)4)]+); the alkali metals form these complexes because their ions are attracted by electrostatic forces of attraction to the polar water molecules. Because of this, anhydrous salts containing alkali metal cations are often used as desiccants. Alkali metals also readily form complexes with crown ethers (e.g. 12-crown-4 for Li+, 15-crown-5 for Na+, 18-crown-6 for K+, and 21-crown-7 for Rb+) and cryptands due to electrostatic attraction. Ammonia solutions The alkali metals dissolve slowly in liquid ammonia, forming ammoniacal solutions of solvated metal cation M+ and solvated electron e−, which react to form hydrogen gas and the alkali metal amide (MNH2, where M represents an alkali metal): this was first noted by Humphry Davy in 1809 and rediscovered by W. Weyl in 1864. The process may be speeded up by a catalyst. Similar solutions are formed by the heavy divalent alkaline earth metals calcium, strontium, barium, as well as the divalent lanthanides, europium and ytterbium. The amide salt is quite insoluble and readily precipitates out of solution, leaving intensely coloured ammonia solutions of the alkali metals. In 1907, Charles Krause identified the colour as being due to the presence of solvated electrons, which contribute to the high electrical conductivity of these solutions. At low concentrations (below 3 M), the solution is dark blue and has ten times the conductivity of aqueous sodium chloride; at higher concentrations (above 3 M), the solution is copper-coloured and has approximately the conductivity of liquid metals like mercury. In addition to the alkali metal amide salt and solvated electrons, such ammonia solutions also contain the alkali metal cation (M+), the neutral alkali metal atom (M), diatomic alkali metal molecules (M2) and alkali metal anions (M−). These are unstable and eventually become the more thermodynamically stable alkali metal amide and hydrogen gas. Solvated electrons are powerful reducing agents and are often used in chemical synthesis. Organometallic Organolithium Being the smallest alkali metal, lithium forms the widest variety of and most stable organometallic compounds, which are bonded covalently. Organolithium compounds are electrically non-conducting volatile solids or liquids that melt at low temperatures, and tend to form oligomers with the structure (RLi)x where R is the organic group. As the electropositive nature of lithium puts most of the charge density of the bond on the carbon atom, effectively creating a carbanion, organolithium compounds are extremely powerful bases and nucleophiles. For use as bases, butyllithiums are often used and are commercially available. An example of an organolithium compound is methyllithium ((CH3Li)x), which exists in tetrameric (x = 4, tetrahedral) and hexameric (x = 6, octahedral) forms. Organolithium compounds, especially n-butyllithium, are useful reagents in organic synthesis, as might be expected given lithium's diagonal relationship with magnesium, which plays an important role in the Grignard reaction. For example, alkyllithiums and aryllithiums may be used to synthesise aldehydes and ketones by reaction with metal carbonyls. The reaction with nickel tetracarbonyl, for example, proceeds through an unstable acyl nickel carbonyl complex which then undergoes electrophilic substitution to give the desired aldehyde (using H+ as the electrophile) or ketone (using an alkyl halide) product. LiR + [Ni(CO)4] Li+[RCONi(CO)3]− Li+[RCONi(CO)3]− Li+ + RCHO + [(solvent)Ni(CO)3] Li+[RCONi(CO)3]− Li+ + R'COR + [(solvent)Ni(CO)3] Alkyllithiums and aryllithiums may also react with N,N-disubstituted amides to give aldehydes and ketones, and symmetrical ketones by reacting with carbon monoxide. They thermally decompose to eliminate a β-hydrogen, producing alkenes and lithium hydride: another route is the reaction of ethers with alkyl- and aryllithiums that act as strong bases. In non-polar solvents, aryllithiums react as the carbanions they effectively are, turning carbon dioxide to aromatic carboxylic acids (ArCO2H) and aryl ketones to tertiary carbinols (Ar'2C(Ar)OH). Finally, they may be used to synthesise other organometallic compounds through metal-halogen exchange. Heavier alkali metals Unlike the organolithium compounds, the organometallic compounds of the heavier alkali metals are predominantly ionic. The application of organosodium compounds in chemistry is limited in part due to competition from organolithium compounds, which are commercially available and exhibit more convenient reactivity. The principal organosodium compound of commercial importance is sodium cyclopentadienide. Sodium tetraphenylborate can also be classified as an organosodium compound since in the solid state sodium is bound to the aryl groups. Organometallic compounds of the higher alkali metals are even more reactive than organosodium compounds and of limited utility. A notable reagent is Schlosser's base, a mixture of n-butyllithium and potassium tert-butoxide. This reagent reacts with propene to form the compound allylpotassium (KCH2CHCH2). cis-2-Butene and trans-2-butene equilibrate when in contact with alkali metals. Whereas isomerisation is fast with lithium and sodium, it is slow with the heavier alkali metals. The heavier alkali metals also favour the sterically congested conformation. Several crystal structures of organopotassium compounds have been reported, establishing that they, like the sodium compounds, are polymeric. Organosodium, organopotassium, organorubidium and organocaesium compounds are all mostly ionic and are insoluble (or nearly so) in nonpolar solvents. Alkyl and aryl derivatives of sodium and potassium tend to react with air. They cause the cleavage of ethers, generating alkoxides. Unlike alkyllithium compounds, alkylsodiums and alkylpotassiums cannot be made by reacting the metals with alkyl halides because Wurtz coupling occurs: RM + R'X → R–R' + MX As such, they have to be made by reacting alkylmercury compounds with sodium or potassium metal in inert hydrocarbon solvents. While methylsodium forms tetramers like methyllithium, methylpotassium is more ionic and has the nickel arsenide structure with discrete methyl anions and potassium cations. The alkali metals and their hydrides react with acidic hydrocarbons, for example cyclopentadienes and terminal alkynes, to give salts. Liquid ammonia, ether, or hydrocarbon solvents are used, the most common of which being tetrahydrofuran. The most important of these compounds is sodium cyclopentadienide, NaC5H5, an important precursor to many transition metal cyclopentadienyl derivatives. Similarly, the alkali metals react with cyclooctatetraene in tetrahydrofuran to give alkali metal cyclooctatetraenides; for example, dipotassium cyclooctatetraenide (K2C8H8) is an important precursor to many metal cyclooctatetraenyl derivatives, such as uranocene. The large and very weakly polarising alkali metal cations can stabilise large, aromatic, polarisable radical anions, such as the dark-green sodium naphthalenide, Na+[C10H8•]−, a strong reducing agent. Representative reactions of alkali metals Reaction with oxygen Upon reacting with oxygen, alkali metals form oxides, peroxides, superoxides and suboxides. However, the first three are more common. The table below shows the types of compounds formed in reaction with oxygen. The compound in brackets represents the minor product of combustion. The alkali metal peroxides are ionic compounds that are unstable in water. The peroxide anion is weakly bound to the cation, and it is hydrolysed, forming stronger covalent bonds. Na2O2 + 2H2O → 2NaOH + H2O2 The other oxygen compounds are also unstable in water. 2KO2 + 2H2O → 2KOH + H2O2 + O2 Li2O + H2O → 2LiOH Reaction with sulfur With sulfur, they form sulfides and polysulfides. 2Na + 1/8S8 → Na2S + 1/8S8 → Na2S2...Na2S7 Because alkali metal sulfides are essentially salts of a weak acid and a strong base, they form basic solutions. S2- + H2O → HS− + HO− HS− + H2O → H2S + HO− Reaction with nitrogen Lithium is the only metal that combines directly with nitrogen at room temperature. 3Li + 1/3N2 → Li3N Li3N can react with water to liberate ammonia. Li3N + 3H2O → 3LiOH + NH3 Reaction with hydrogen With hydrogen, alkali metals form saline hydrides that hydrolyse in water. Na + H2 → NaH (at high temperatures) NaH + H2O → NaOH + H2 Reaction with carbon Lithium is the only metal that reacts directly with carbon to give dilithium acetylide. Na and K can react with acetylene to give acetylides. 2Li + 2C → Li2C2 Na + C2H2 → NaC2H + 1/2H2 (at 1500C) Na + NaC2H → Na2C2 (at 2200C) Reaction with water On reaction with water, they generate hydroxide ions and hydrogen gas. This reaction is vigorous and highly exothermic and the hydrogen resulted may ignite in air or even explode in the case of Rb and Cs. Na + H2O → NaOH + 1/2H2 Reaction with other salts The alkali metals are very good reducing agents. They can reduce metal cations that are less electropositive. Titanium is produced industrially by the reduction of titanium tetrachloride with Na at 4000C (van Arkel–de Boer process). TiCl4 + 4Na → 4NaCl + Ti Reaction with organohalide compounds Alkali metals react with halogen derivatives to generate hydrocarbon via the Wurtz reaction. 2CH3-Cl + 2Na → H3C-CH3 + 2NaCl Alkali metals in liquid ammonia Alkali metals dissolve in liquid ammonia or other donor solvents like aliphatic amines or hexamethylphosphoramide to give blue solutions. These solutions are believed to contain free electrons. Na + xNH3 → Na+ + e(NH3)x− Due to the presence of solvated electrons, these solutions are very powerful reducing agents used in organic synthesis. Reaction 1) is known as Birch reduction. Other reductions that can be carried by these solutions are: S8 + 2e− → S82- Fe(CO)5 + 2e− → Fe(CO)42- + CO Extensions Although francium is the heaviest alkali metal that has been discovered, there has been some theoretical work predicting the physical and chemical characteristics of hypothetical heavier alkali metals. Being the first period 8 element, the undiscovered element ununennium (element 119) is predicted to be the next alkali metal after francium and behave much like their lighter congeners; however, it is also predicted to differ from the lighter alkali metals in some properties. Its chemistry is predicted to be closer to that of potassium or rubidium instead of caesium or francium. This is unusual as periodic trends, ignoring relativistic effects would predict ununennium to be even more reactive than caesium and francium. This lowered reactivity is due to the relativistic stabilisation of ununennium's valence electron, increasing ununennium's first ionisation energy and decreasing the metallic and ionic radii; this effect is already seen for francium. This assumes that ununennium will behave chemically as an alkali metal, which, although likely, may not be true due to relativistic effects. The relativistic stabilisation of the 8s orbital also increases ununennium's electron affinity far beyond that of caesium and francium; indeed, ununennium is expected to have an electron affinity higher than all the alkali metals lighter than it. Relativistic effects also cause a very large drop in the polarisability of ununennium. On the other hand, ununennium is predicted to continue the trend of melting points decreasing going down the group, being expected to have a melting point between 0 °C and 30 °C. The stabilisation of ununennium's valence electron and thus the contraction of the 8s orbital cause its atomic radius to be lowered to 240 pm, very close to that of rubidium (247 pm), so that the chemistry of ununennium in the +1 oxidation state should be more similar to the chemistry of rubidium than to that of francium. On the other hand, the ionic radius of the Uue+ ion is predicted to be larger than that of Rb+, because the 7p orbitals are destabilised and are thus larger than the p-orbitals of the lower shells. Ununennium may also show the +3 oxidation state, which is not seen in any other alkali metal, in addition to the +1 oxidation state that is characteristic of the other alkali metals and is also the main oxidation state of all the known alkali metals: this is because of the destabilisation and expansion of the 7p3/2 spinor, causing its outermost electrons to have a lower ionisation energy than what would otherwise be expected. Indeed, many ununennium compounds are expected to have a large covalent character, due to the involvement of the 7p3/2 electrons in the bonding. Not as much work has been done predicting the properties of the alkali metals beyond ununennium. Although a simple extrapolation of the periodic table (by the aufbau principle) would put element 169, unhexennium, under ununennium, Dirac-Fock calculations predict that the next element after ununennium with alkali-metal-like properties may be element 165, unhexpentium, which is predicted to have the electron configuration [Og] 5g18 6f14 7d10 8s2 8p1/22 9s1. This element would be intermediate in properties between an alkali metal and a group 11 element, and while its physical and atomic properties would be closer to the former, its chemistry may be closer to that of the latter. Further calculations show that unhexpentium would follow the trend of increasing ionisation energy beyond caesium, having an ionisation energy comparable to that of sodium, and that it should also continue the trend of decreasing atomic radii beyond caesium, having an atomic radius comparable to that of potassium. However, the 7d electrons of unhexpentium may also be able to participate in chemical reactions along with the 9s electron, possibly allowing oxidation states beyond +1, whence the likely transition metal behaviour of unhexpentium. Due to the alkali and alkaline earth metals both being s-block elements, these predictions for the trends and properties of ununennium and unhexpentium also mostly hold quite similarly for the corresponding alkaline earth metals unbinilium (Ubn) and unhexhexium (Uhh). Unsepttrium, element 173, may be an even better heavier homologue of ununennium; with a predicted electron configuration of [Usb] 6g1, it returns to the alkali-metal-like situation of having one easily removed electron far above a closed p-shell in energy, and is expected to be even more reactive than caesium. The probable properties of further alkali metals beyond unsepttrium have not been explored yet as of 2019, and they may or may not be able to exist. In periods 8 and above of the periodic table, relativistic and shell-structure effects become so strong that extrapolations from lighter congeners become completely inaccurate. In addition, the relativistic and shell-structure effects (which stabilise the s-orbitals and destabilise and expand the d-, f-, and g-orbitals of higher shells) have opposite effects, causing even larger difference between relativistic and non-relativistic calculations of the properties of elements with such high atomic numbers. Interest in the chemical properties of ununennium, unhexpentium, and unsepttrium stems from the fact that they are located close to the expected locations of islands of stability, centered at elements 122 (306Ubb) and 164 (482Uhq). Pseudo-alkali metals Many other substances are similar to the alkali metals in their tendency to form monopositive cations. Analogously to the pseudohalogens, they have sometimes been called "pseudo-alkali metals". These substances include some elements and many more polyatomic ions; the polyatomic ions are especially similar to the alkali metals in their large size and weak polarising power. Hydrogen The element hydrogen, with one electron per neutral atom, is usually placed at the top of Group 1 of the periodic table for convenience, but hydrogen is not normally considered to be an alkali metal; when it is considered to be an alkali metal, it is because of its atomic properties and not its chemical properties. Under typical conditions, pure hydrogen exists as a diatomic gas consisting of two atoms per molecule (H2); however, the alkali metals form diatomic molecules (such as dilithium, Li2) only at high temperatures, when they are in the gaseous state. Hydrogen, like the alkali metals, has one valence electron and reacts easily with the halogens, but the similarities mostly end there because of the small size of a bare proton H+ compared to the alkali metal cations. Its placement above lithium is primarily due to its electron configuration. It is sometimes placed above fluorine due to their similar chemical properties, though the resemblance is likewise not absolute. The first ionisation energy of hydrogen (1312.0 kJ/mol) is much higher than that of the alkali metals. As only one additional electron is required to fill in the outermost shell of the hydrogen atom, hydrogen often behaves like a halogen, forming the negative hydride ion, and is very occasionally considered to be a halogen on that basis. (The alkali metals can also form negative ions, known as alkalides, but these are little more than laboratory curiosities, being unstable.) An argument against this placement is that formation of hydride from hydrogen is endothermic, unlike the exothermic formation of halides from halogens. The radius of the H− anion also does not fit the trend of increasing size going down the halogens: indeed, H− is very diffuse because its single proton cannot easily control both electrons. It was expected for some time that liquid hydrogen would show metallic properties; while this has been shown to not be the case, under extremely high pressures, such as those found at the cores of Jupiter and Saturn, hydrogen does become metallic and behaves like an alkali metal; in this phase, it is known as metallic hydrogen. The electrical resistivity of liquid metallic hydrogen at 3000 K is approximately equal to that of liquid rubidium and caesium at 2000 K at the respective pressures when they undergo a nonmetal-to-metal transition. The 1s1 electron configuration of hydrogen, while analogous to that of the alkali metals (ns1), is unique because there is no 1p subshell. Hence it can lose an electron to form the hydron H+, or gain one to form the hydride ion H−. In the former case it resembles superficially the alkali metals; in the latter case, the halogens, but the differences due to the lack of a 1p subshell are important enough that neither group fits the properties of hydrogen well. Group 14 is also a good fit in terms of thermodynamic properties such as ionisation energy and electron affinity, but hydrogen cannot be tetravalent. Thus none of the three placements are entirely satisfactory, although group 1 is the most common placement (if one is chosen) because the hydron is by far the most important of all monatomic hydrogen species, being the foundation of acid-base chemistry. As an example of hydrogen's unorthodox properties stemming from its unusual electron configuration and small size, the hydrogen ion is very small (radius around 150 fm compared to the 50–220 pm size of most other atoms and ions) and so is nonexistent in condensed systems other than in association with other atoms or molecules. Indeed, transferring of protons between chemicals is the basis of acid-base chemistry. Also unique is hydrogen's ability to form hydrogen bonds, which are an effect of charge-transfer, electrostatic, and electron correlative contributing phenomena. While analogous lithium bonds are also known, they are mostly electrostatic. Nevertheless, hydrogen can take on the same structural role as the alkali metals in some molecular crystals, and has a close relationship with the lightest alkali metals (especially lithium). Ammonium and derivatives The ammonium ion () has very similar properties to the heavier alkali metals, acting as an alkali metal intermediate between potassium and rubidium, and is often considered a close relative. For example, most alkali metal salts are soluble in water, a property which ammonium salts share. Ammonium is expected to behave stably as a metal ( ions in a sea of delocalised electrons) at very high pressures (though less than the typical pressure where transitions from insulating to metallic behaviour occur around, 100 GPa), and could possibly occur inside the ice giants Uranus and Neptune, which may have significant impacts on their interior magnetic fields. It has been estimated that the transition from a mixture of ammonia and dihydrogen molecules to metallic ammonium may occur at pressures just below 25 GPa. Under standard conditions, ammonium can form a metallic amalgam with mercury. Other "pseudo-alkali metals" include the alkylammonium cations, in which some of the hydrogen atoms in the ammonium cation are replaced by alkyl or aryl groups. In particular, the quaternary ammonium cations () are very useful since they are permanently charged, and they are often used as an alternative to the expensive Cs+ to stabilise very large and very easily polarisable anions such as . Tetraalkylammonium hydroxides, like alkali metal hydroxides, are very strong bases that react with atmospheric carbon dioxide to form carbonates. Furthermore, the nitrogen atom may be replaced by a phosphorus, arsenic, or antimony atom (the heavier nonmetallic pnictogens), creating a phosphonium () or arsonium () cation that can itself be substituted similarly; while stibonium () itself is not known, some of its organic derivatives are characterised. Cobaltocene and derivatives Cobaltocene, Co(C5H5)2, is a metallocene, the cobalt analogue of ferrocene. It is a dark purple solid. Cobaltocene has 19 valence electrons, one more than usually found in organotransition metal complexes, such as its very stable relative, ferrocene, in accordance with the 18-electron rule. This additional electron occupies an orbital that is antibonding with respect to the Co–C bonds. Consequently, many chemical reactions of Co(C5H5)2 are characterized by its tendency to lose this "extra" electron, yielding a very stable 18-electron cation known as cobaltocenium. Many cobaltocenium salts coprecipitate with caesium salts, and cobaltocenium hydroxide is a strong base that absorbs atmospheric carbon dioxide to form cobaltocenium carbonate. Like the alkali metals, cobaltocene is a strong reducing agent, and decamethylcobaltocene is stronger still due to the combined inductive effect of the ten methyl groups. Cobalt may be substituted by its heavier congener rhodium to give rhodocene, an even stronger reducing agent. Iridocene (involving iridium) would presumably be still more potent, but is not very well-studied due to its instability. Thallium Thallium is the heaviest stable element in group 13 of the periodic table. At the bottom of the periodic table, the inert pair effect is quite strong, because of the relativistic stabilisation of the 6s orbital and the decreasing bond energy as the atoms increase in size so that the amount of energy released in forming two more bonds is not worth the high ionisation energies of the 6s electrons. It displays the +1 oxidation state that all the known alkali metals display, and thallium compounds with thallium in its +1 oxidation state closely resemble the corresponding potassium or silver compounds stoichiometrically due to the similar ionic radii of the Tl+ (164 pm), K+ (152 pm) and Ag+ (129 pm) ions. It was sometimes considered an alkali metal in continental Europe (but not in England) in the years immediately following its discovery, and was placed just after caesium as the sixth alkali metal in Dmitri Mendeleev's 1869 periodic table and Julius Lothar Meyer's 1868 periodic table. (Mendeleev's 1871 periodic table and Meyer's 1870 periodic table put thallium in its current position in the boron group and left the space below caesium blank.) However, thallium also displays the oxidation state +3, which no known alkali metal displays (although ununennium, the undiscovered seventh alkali metal, is predicted to possibly display the +3 oxidation state). The sixth alkali metal is now considered to be francium. While Tl+ is stabilised by the inert pair effect, this inert pair of 6s electrons is still able to participate chemically, so that these electrons are stereochemically active in aqueous solution. Additionally, the thallium halides (except TlF) are quite insoluble in water, and TlI has an unusual structure because of the presence of the stereochemically active inert pair in thallium. Copper, silver, and gold The group 11 metals (or coinage metals), copper, silver, and gold, are typically categorised as transition metals given they can form ions with incomplete d-shells. Physically, they have the relatively low melting points and high electronegativity values associated with post-transition metals. "The filled d subshell and free s electron of Cu, Ag, and Au contribute to their high electrical and thermal conductivity. Transition metals to the left of group 11 experience interactions between s electrons and the partially filled d subshell that lower electron mobility." Chemically, the group 11 metals behave like main-group metals in their +1 valence states, and are hence somewhat related to the alkali metals: this is one reason for their previously being labelled as "group IB", paralleling the alkali metals' "group IA". They are occasionally classified as post-transition metals. Their spectra are analogous to those of the alkali metals. Their monopositive ions are paramagnetic and contribute no colour to their salts, like those of the alkali metals. In Mendeleev's 1871 periodic table, copper, silver, and gold are listed twice, once under group VIII (with the iron triad and platinum group metals), and once under group IB. Group IB was nonetheless parenthesised to note that it was tentative. Mendeleev's main criterion for group assignment was the maximum oxidation state of an element: on that basis, the group 11 elements could not be classified in group IB, due to the existence of copper(II) and gold(III) compounds being known at that time. However, eliminating group IB would make group I the only main group (group VIII was labelled a transition group) to lack an A–B bifurcation. Soon afterward, a majority of chemists chose to classify these elements in group IB and remove them from group VIII for the resulting symmetry: this was the predominant classification until the rise of the modern medium-long 18-column periodic table, which separated the alkali metals and group 11 metals. The coinage metals were traditionally regarded as a subdivision of the alkali metal group, due to them sharing the characteristic s1 electron configuration of the alkali metals (group 1: p6s1; group 11: d10s1). However, the similarities are largely confined to the stoichiometries of the +1 compounds of both groups, and not their chemical properties. This stems from the filled d subshell providing a much weaker shielding effect on the outermost s electron than the filled p subshell, so that the coinage metals have much higher first ionisation energies and smaller ionic radii than do the corresponding alkali metals. Furthermore, they have higher melting points, hardnesses, and densities, and lower reactivities and solubilities in liquid ammonia, as well as having more covalent character in their compounds. Finally, the alkali metals are at the top of the electrochemical series, whereas the coinage metals are almost at the very bottom. The coinage metals' filled d shell is much more easily disrupted than the alkali metals' filled p shell, so that the second and third ionisation energies are lower, enabling higher oxidation states than +1 and a richer coordination chemistry, thus giving the group 11 metals clear transition metal character. Particularly noteworthy is gold forming ionic compounds with rubidium and caesium, in which it forms the auride ion (Au−) which also occurs in solvated form in liquid ammonia solution: here gold behaves as a pseudohalogen because its 5d106s1 configuration has one electron less than the quasi-closed shell 5d106s2 configuration of mercury. Production and isolation The production of pure alkali metals is somewhat complicated due to their extreme reactivity with commonly used substances, such as water. From their silicate ores, all the stable alkali metals may be obtained the same way: sulfuric acid is first used to dissolve the desired alkali metal ion and aluminium(III) ions from the ore (leaching), whereupon basic precipitation removes aluminium ions from the mixture by precipitating it as the hydroxide. The remaining insoluble alkali metal carbonate is then precipitated selectively; the salt is then dissolved in hydrochloric acid to produce the chloride. The result is then left to evaporate and the alkali metal can then be isolated. Lithium and sodium are typically isolated through electrolysis from their liquid chlorides, with calcium chloride typically added to lower the melting point of the mixture. The heavier alkali metals, however, are more typically isolated in a different way, where a reducing agent (typically sodium for potassium and magnesium or calcium for the heaviest alkali metals) is used to reduce the alkali metal chloride. The liquid or gaseous product (the alkali metal) then undergoes fractional distillation for purification. Most routes to the pure alkali metals require the use of electrolysis due to their high reactivity; one of the few which does not is the pyrolysis of the corresponding alkali metal azide, which yields the metal for sodium, potassium, rubidium, and caesium and the nitride for lithium. Lithium salts have to be extracted from the water of mineral springs, brine pools, and brine deposits. The metal is produced electrolytically from a mixture of fused lithium chloride and potassium chloride. Sodium occurs mostly in seawater and dried seabed, but is now produced through electrolysis of sodium chloride by lowering the melting point of the substance to below 700 °C through the use of a Downs cell. Extremely pure sodium can be produced through the thermal decomposition of sodium azide. Potassium occurs in many minerals, such as sylvite (potassium chloride). Previously, potassium was generally made from the electrolysis of potassium chloride or potassium hydroxide, found extensively in places such as Canada, Russia, Belarus, Germany, Israel, United States, and Jordan, in a method similar to how sodium was produced in the late 1800s and early 1900s. It can also be produced from seawater. However, these methods are problematic because the potassium metal tends to dissolve in its molten chloride and vaporises significantly at the operating temperatures, potentially forming the explosive superoxide. As a result, pure potassium metal is now produced by reducing molten potassium chloride with sodium metal at 850 °C. Na (g) + KCl (l) NaCl (l) + K (g) Although sodium is less reactive than potassium, this process works because at such high temperatures potassium is more volatile than sodium and can easily be distilled off, so that the equilibrium shifts towards the right to produce more potassium gas and proceeds almost to completion. Metals like sodium are obtained by electrolysis of molten salts. Rb & Cs obtained mainly as by products of Li processing. To make pure cesium, ores of cesium and rubidium are crushed and heated to 650 °C with sodium metal, generating an alloy that can then be separated via a fractional distillation technique. Because metallic cesium is too reactive to handle, it is normally offered as cesium azide (CsN3). Cesium hydroxide is formed when cesium interacts aggressively with water and ice (CsOH). Rubidium is the 16th most prevalent element in the earth's crust, however it is quite rare. Some minerals found in North America, South Africa, Russia, and Canada contain rubidium. Some potassium minerals (lepidolites, biotites, feldspar, carnallite) contain it, together with caesium. Pollucite, carnallite, leucite, and lepidolite are all minerals that contain rubidium. As a by-product of lithium extraction, it is commercially obtained from lepidolite. Rubidium is also found in potassium rocks and brines, which is a commercial supply. The majority of rubidium is now obtained as a byproduct of refining lithium. Rubidium is used in vacuum tubes as a getter, a material that combines with and removes trace gases from vacuum tubes. For several years in the 1950s and 1960s, a by-product of the potassium production called Alkarb was a main source for rubidium. Alkarb contained 21% rubidium while the rest was potassium and a small fraction of caesium. Today the largest producers of caesium, for example the Tanco Mine in Manitoba, Canada, produce rubidium as by-product from pollucite. Today, a common method for separating rubidium from potassium and caesium is the fractional crystallisation of a rubidium and caesium alum (Cs, Rb)Al(SO4)2·12H2O, which yields pure rubidium alum after approximately 30 recrystallisations. The limited applications and the lack of a mineral rich in rubidium limit the production of rubidium compounds to 2 to 4 tonnes per year. Caesium, however, is not produced from the above reaction. Instead, the mining of pollucite ore is the main method of obtaining pure caesium, extracted from the ore mainly by three methods: acid digestion, alkaline decomposition, and direct reduction. Both metals are produced as by-products of lithium production: after 1958, when interest in lithium's thermonuclear properties increased sharply, the production of rubidium and caesium also increased correspondingly. Pure rubidium and caesium metals are produced by reducing their chlorides with calcium metal at 750 °C and low pressure. As a result of its extreme rarity in nature, most francium is synthesised in the nuclear reaction 197Au + 18O → 210Fr + 5 n, yielding francium-209, francium-210, and francium-211. The greatest quantity of francium ever assembled to date is about 300,000 neutral atoms, which were synthesised using the nuclear reaction given above. When the only natural isotope francium-223 is specifically required, it is produced as the alpha daughter of actinium-227, itself produced synthetically from the neutron irradiation of natural radium-226, one of the daughters of natural uranium-238. Applications Lithium, sodium, and potassium have many applications, while rubidium and caesium are very useful in academic contexts but do not have many applications yet. Lithium is often used in lithium-ion batteries, and lithium oxide can help process silica. Lithium stearate is a thickener and can be used to make lubricating greases; it is produced from lithium hydroxide, which is also used to absorb carbon dioxide in space capsules and submarines. Lithium chloride is used as a brazing alloy for aluminium parts. Metallic lithium is used in alloys with magnesium and aluminium to give very tough and light alloys. Sodium compounds have many applications, the most well-known being sodium chloride as table salt. Sodium salts of fatty acids are used as soap. Pure sodium metal also has many applications, including use in sodium-vapour lamps, which produce very efficient light compared to other types of lighting, and can help smooth the surface of other metals. Being a strong reducing agent, it is often used to reduce many other metals, such as titanium and zirconium, from their chlorides. Furthermore, it is very useful as a heat-exchange liquid in fast breeder nuclear reactors due to its low melting point, viscosity, and cross-section towards neutron absorption. Potassium compounds are often used as fertilisers as potassium is an important element for plant nutrition. Potassium hydroxide is a very strong base, and is used to control the pH of various substances. Potassium nitrate and potassium permanganate are often used as powerful oxidising agents. Potassium superoxide is used in breathing masks, as it reacts with carbon dioxide to give potassium carbonate and oxygen gas. Pure potassium metal is not often used, but its alloys with sodium may substitute for pure sodium in fast breeder nuclear reactors. Rubidium and caesium are often used in atomic clocks. Caesium atomic clocks are extraordinarily accurate; if a clock had been made at the time of the dinosaurs, it would be off by less than four seconds (after 80 million years). For that reason, caesium atoms are used as the definition of the second. Rubidium ions are often used in purple fireworks, and caesium is often used in drilling fluids in the petroleum industry. Francium has no commercial applications, but because of francium's relatively simple atomic structure, among other things, it has been used in spectroscopy experiments, leading to more information regarding energy levels and the coupling constants between subatomic particles. Studies on the light emitted by laser-trapped francium-210 ions have provided accurate data on transitions between atomic energy levels, similar to those predicted by quantum theory. Biological role and precautions Metals Pure alkali metals are dangerously reactive with air and water and must be kept away from heat, fire, oxidising agents, acids, most organic compounds, halocarbons, plastics, and moisture. They also react with carbon dioxide and carbon tetrachloride, so that normal fire extinguishers are counterproductive when used on alkali metal fires. Some Class D dry powder extinguishers designed for metal fires are effective, depriving the fire of oxygen and cooling the alkali metal. Experiments are usually conducted using only small quantities of a few grams in a fume hood. Small quantities of lithium may be disposed of by reaction with cool water, but the heavier alkali metals should be dissolved in the less reactive isopropanol. The alkali metals must be stored under mineral oil or an inert atmosphere. The inert atmosphere used may be argon or nitrogen gas, except for lithium, which reacts with nitrogen. Rubidium and caesium must be kept away from air, even under oil, because even a small amount of air diffused into the oil may trigger formation of the dangerously explosive peroxide; for the same reason, potassium should not be stored under oil in an oxygen-containing atmosphere for longer than 6 months. Ions The bioinorganic chemistry of the alkali metal ions has been extensively reviewed. Solid state crystal structures have been determined for many complexes of alkali metal ions in small peptides, nucleic acid constituents, carbohydrates and ionophore complexes. Lithium naturally only occurs in traces in biological systems and has no known biological role, but does have effects on the body when ingested. Lithium carbonate is used as a mood stabiliser in psychiatry to treat bipolar disorder (manic-depression) in daily doses of about 0.5 to 2 grams, although there are side-effects. Excessive ingestion of lithium causes drowsiness, slurred speech and vomiting, among other symptoms, and poisons the central nervous system, which is dangerous as the required dosage of lithium to treat bipolar disorder is only slightly lower than the toxic dosage. Its biochemistry, the way it is handled by the human body and studies using rats and goats suggest that it is an essential trace element, although the natural biological function of lithium in humans has yet to be identified. Sodium and potassium occur in all known biological systems, generally functioning as electrolytes inside and outside cells. Sodium is an essential nutrient that regulates blood volume, blood pressure, osmotic equilibrium and pH; the minimum physiological requirement for sodium is 500 milligrams per day. Sodium chloride (also known as common salt) is the principal source of sodium in the diet, and is used as seasoning and preservative, such as for pickling and jerky; most of it comes from processed foods. The Dietary Reference Intake for sodium is 1.5 grams per day, but most people in the United States consume more than 2.3 grams per day, the minimum amount that promotes hypertension; this in turn causes 7.6 million premature deaths worldwide. Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential. The balance between potassium and sodium is maintained by ion transporter proteins in the cell membrane. The cell membrane potential created by potassium and sodium ions allows the cell to generate an action potential—a "spike" of electrical discharge. The ability of cells to produce electrical discharge is critical for body functions such as neurotransmission, muscle contraction, and heart function. Disruption of this balance may thus be fatal: for example, ingestion of large amounts of potassium compounds can lead to hyperkalemia strongly influencing the cardiovascular system. Potassium chloride is used in the United States for lethal injection executions. Due to their similar atomic radii, rubidium and caesium in the body mimic potassium and are taken up similarly. Rubidium has no known biological role, but may help stimulate metabolism, and, similarly to caesium, replace potassium in the body causing potassium deficiency. Partial substitution is quite possible and rather non-toxic: a 70 kg person contains on average 0.36 g of rubidium, and an increase in this value by 50 to 100 times did not show negative effects in test persons. Rats can survive up to 50% substitution of potassium by rubidium. Rubidium (and to a much lesser extent caesium) can function as temporary cures for hypokalemia; while rubidium can adequately physiologically substitute potassium in some systems, caesium is never able to do so. There is only very limited evidence in the form of deficiency symptoms for rubidium being possibly essential in goats; even if this is true, the trace amounts usually present in food are more than enough. Caesium compounds are rarely encountered by most people, but most caesium compounds are mildly toxic. Like rubidium, caesium tends to substitute potassium in the body, but is significantly larger and is therefore a poorer substitute. Excess caesium can lead to hypokalemia, arrythmia, and acute cardiac arrest, but such amounts would not ordinarily be encountered in natural sources. As such, caesium is not a major chemical environmental pollutant. The median lethal dose (LD50) value for caesium chloride in mice is 2.3 g per kilogram, which is comparable to the LD50 values of potassium chloride and sodium chloride. Caesium chloride has been promoted as an alternative cancer therapy, but has been linked to the deaths of over 50 patients, on whom it was used as part of a scientifically unvalidated cancer treatment. Radioisotopes of caesium require special precautions: the improper handling of caesium-137 gamma ray sources can lead to release of this radioisotope and radiation injuries. Perhaps the best-known case is the Goiânia accident of 1987, in which an improperly-disposed-of radiation therapy system from an abandoned clinic in the city of Goiânia, Brazil, was scavenged from a junkyard, and the glowing caesium salt sold to curious, uneducated buyers. This led to four deaths and serious injuries from radiation exposure. Together with caesium-134, iodine-131, and strontium-90, caesium-137 was among the isotopes distributed by the Chernobyl disaster which constitute the greatest risk to health. Radioisotopes of francium would presumably be dangerous as well due to their high decay energy and short half-life, but none have been produced in large enough amounts to pose any serious risk.

Actinopterygii (; ), members of which are known as ray-finned fishes, is a clade (traditionally class or subclass) of the bony fishes. They comprise over 50% of living vertebrate species. The ray-finned fishes are so-called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they comprise nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from Paedocypris, at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopterygii (~95%) are teleosts. Characteristics Ray-finned fishes occur in many variant forms. The main features of a typical ray-finned fish are shown in the adjacent diagram. The swim bladder is the more derived structure. Ray-finned fishes have many different types of scales; but all teleosts, the most advanced actinopterygians, have leptoid scales. The outer part of these scales fan out with bony ridges while the inner part is crossed with fibrous connective tissue. Leptoid scales are thinner and more transparent than other types of scales, and lack the hardened enamel or dentine-like layers found in the scales of many other fish. Unlike ganoid scales, which are found in non-teleost actinopterygians, new scales are added in concentric layers as the fish grows. Ray-finned and lobe-finned fishes, including tetrapods, possessed lungs used for aerial respiration. Only bichirs retain ventrally budding lungs. Body shapes and fin arrangements Ray-finned fish vary in size and shape, in their feeding specializations, and in the number and arrangement of their ray-fins. Reproduction In nearly all ray-finned fish, the sexes are separate, and in most species the females spawn eggs that are fertilized externally, typically with the male inseminating the eggs after they are laid. Development then proceeds with a free-swimming larval stage. However other patterns of ontogeny exist, with one of the commonest being sequential hermaphroditism. In most cases this involves protogyny, fish starting life as females and converting to males at some stage, triggered by some internal or external factor. Protandry, where a fish converts from male to female, is much less common than protogyny. Most families use external rather than internal fertilization. Of the oviparous teleosts, most (79%) do not provide parental care. Viviparity, ovoviviparity, or some form of parental care for eggs, whether by the male, the female, or both parents is seen in a significant fraction (21%) of the 422 teleost families; no care is likely the ancestral condition. The oldest case of viviparity in ray-finned fish is found in Middle Triassic species of Saurichthys. Viviparity is relatively rare and is found in about 6% of living teleost species; male care is far more common than female care. Male territoriality "preadapts" a species for evolving male parental care. There are a few examples of fish that self-fertilise. The mangrove rivulus is an amphibious, simultaneous hermaphrodite, producing both eggs and spawn and having internal fertilisation. This mode of reproduction may be related to the fish's habit of spending long periods out of water in the mangrove forests it inhabits. Males are occasionally produced at temperatures below and can fertilise eggs that are then spawned by the female. This maintains genetic variability in a species that is otherwise highly inbred. Classification and fossil record Actinopterygii is divided into the classes Cladistia and Actinopteri. The latter comprises the subclasses Chondrostei and Neopterygii. The Neopterygii, in turn, is divided into the infraclasses Holostei and Teleostei. During the Mesozoic (Triassic, Jurassic, Cretaceous) and Cenozoic the teleosts in particular diversified widely. As a result, 96% of living fish species are teleosts (40% of all fish species belong to the teleost subgroup Acanthomorpha), while all other groups of actinopterygians represent depauperate lineages. The classification of ray-finned fishes can be summarized as follows: Cladistia, which include bichirs and reedfish Actinopteri, which include: Chondrostei, which include Acipenseriformes (paddlefishes and sturgeons) Neopterygii, which include: Teleostei (most living fishes) Holostei, which include: Lepisosteiformes (gars) Amiiformes (bowfin) The cladogram below shows the main clades of living actinopterygians and their evolutionary relationships to other extant groups of fishes and the four-limbed vertebrates (tetrapods). The latter include mostly terrestrial species but also groups that became secondarily aquatic (e.g. Whales and Dolphins). Tetrapods evolved from a group of bony fish during the Devonian period. Approximate divergence dates for the different actinopterygian clades (in millions of years, mya) are from Near et al., 2012. The polypterids (bichirs and reedfish) are the sister lineage of all other actinopterygians, the Acipenseriformes (sturgeons and paddlefishes) are the sister lineage of Neopterygii, and Holostei (bowfin and gars) are the sister lineage of teleosts. The Elopomorpha (eels and tarpons) appear to be the most basal teleosts. The earliest known fossil actinopterygian is Andreolepis hedei, dating back 420 million years (Late Silurian). Remains have been found in Russia, Sweden, and Estonia. The earliest fossil relatives of modern teleosts are from the Triassic period (Prohalecites, Pholidophorus), although it is suspected that teleosts originated already during the Paleozoic Era. Taxonomy The listing below is a summary of all extinct (indicated by a dagger, †) and living groups of Actinopterygii with their respcective taxonomic rank.

An ( ; Medieval Latin for "he has declared under oath") is a written statement voluntarily made by an affiant or deponent under an oath or affirmation which is administered by a person who is authorized to do so by law. Such a statement is witnessed as to the authenticity of the affiant's signature by a taker of oaths, such as a notary public or commissioner of oaths. An affidavit is a type of verified statement or showing, or in other words, it contains a verification, which means that it is made under oath on penalty of perjury, and this serves as evidence for its veracity and is required in court proceedings. Definition An affidavit is typically defined as a written declaration or statement that is sworn or affirmed before a person who has authority to administer an oath. There is no general defined form for an affidavit, although for some proceedings an affidavit must satisfy legal or statutory requirements in order to be considered. An affidavit may include, a commencement which identifies the affiant; an attestation clause, usually a jurat, at the end certifying that the affiant made the statement under oath on the specified date; signatures of the affiant and person who administered the oath. In some cases, an introductory clause, called a preamble, is added attesting that the affiant personally appeared before the authenticating authority. An affidavit may also recite that the statement it records was made under penalty of perjury. An affidavit that is prepared for use within the context of litigation may also include a caption that identifies the venue and parties to the relevant judicial proceedings. Worldwide Australia On 2 March 2016, the High Court of Australia held that the ACT Uniform Evidence Legislation is neutral in the way sworn evidence and unsworn evidence is treated as being of equal weight. India In Indian law, although an affidavit may be taken as proof of the facts stated therein, the courts have no jurisdiction to admit evidence by way of affidavit. Affidavit is not treated as "evidence" within the meaning of Section 3 of the Evidence Act. However, it was held by the Supreme Court that an affidavit can be used as evidence only if the court so orders for sufficient reasons, namely, the right of the opposite party to have the deponent produced for cross-examination. Therefore, an affidavit cannot ordinarily be used as evidence in absence of a specific order of the court. Sri Lanka In Sri Lanka, under the Oaths Ordinance, with the exception of a court-martial, a person may submit an affidavit signed in the presence of a commissioner for oaths or a justice of the peace. Ireland Affidavits are made in a similar way as to England and Wales, although "make oath" is sometimes omitted. An affirmed affidavit may be substituted for an sworn affidavit in most cases for those opposed to swearing oaths. The person making the affidavit is known as the deponent and signs the affidavit. The affidavit concludes in the standard format "sworn/affirmed (declared) before me, [name of commissioner for oaths/solicitor], a commissioner for oaths (solicitor), on the [date] at [location] in the county/city of [county/city], and I know the deponent", and it is signed and stamped by the commissioner for oaths. It is important that the Commissioner states his/her name clearly, sometimes documents are rejected when the name cannot be ascertained. In August 2020, a new method of filing affidavits came into force. Under Section 21 of the Civil Law and Criminal Law (Miscellaneous Provisions) Act 2020 witnesses are no longer required to swear before God or make an affirmation when filing an affidavit. Instead, witnesses will make a non-religious “statement of truth” and, if it is breached, will be liable for up to one year in prison if convicted summarily or, upon conviction on indictment, to a maximum fine of €250,000 or imprisonment for a term not exceeding 5 years, or both. This is designed to replace affidavits and statutory declarations in situations where the electronic means of lodgement or filing of documents with the Court provided for in Section 20 is utilised. As of January 2022, it has yet to be adopted widely, and it is expected it will not be used for some time by lay litigants who will still lodge papers in person. United States In American jurisprudence, under the rules for hearsay, admission of an unsupported affidavit as evidence is unusual (especially if the affiant is not available for cross-examination) with regard to material facts which may be dispositive of the matter at bar. Affidavits from persons who are dead or otherwise incapacitated, or who cannot be located or made to appear, may be accepted by the court, but usually only in the presence of corroborating evidence. An affidavit which reflected a better grasp of the facts close in time to the actual events may be used to refresh a witness's recollection. Materials used to refresh recollection are admissible as evidence. If the affiant is a party in the case, the affiant's opponent may be successful in having the affidavit admitted as evidence, as statements by a party-opponent are admissible through an exception to the hearsay rule. Affidavits are typically included in the response to interrogatories. Requests for admissions under Federal Rule of Civil Procedure 36, however, are not required to be sworn. When a person signs an affidavit, that person is eligible to take the stand at a trial or evidentiary hearing. One party may wish to summon the affiant to verify the contents of the affidavit, while the other party may want to cross-examine the affiant about the affidavit. Some types of motions will not be accepted by the court unless accompanied by an independent sworn statement or other evidence in support of the need for the motion. In such a case, a court will accept an affidavit from the filing attorney in support of the motion, as certain assumptions are made, to wit: The affidavit in place of sworn testimony promotes judicial economy. The lawyer is an officer of the court and knows that a false swearing by them, if found out, could be grounds for severe penalty up to and including disbarment. The lawyer if called upon would be able to present independent and more detailed evidence to prove the facts set forth in his affidavit. The acceptance of an affidavit by one society does not confirm its acceptance as a legal document in other jurisdictions. Equally, the acceptance that a lawyer is an officer of the court (for swearing the affidavit) is not a given. This matter is addressed by the use of the apostille, a means of certifying the legalization of a document for international use under the terms of the 1961 Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents. Documents which have been notarized by a notary public, and certain other documents, and then certified with a conformant apostille, are accepted for legal use in all the nations that have signed the Hague Convention. Thus most affidavits now require to be apostilled if used for cross border issues.

Ancient Egypt was a civilization of ancient Africa, concentrated along the lower reaches of the Nile River, situated in the place that is now the country Egypt. Ancient Egyptian civilization followed prehistoric Egypt and coalesced around 3100BC (according to conventional Egyptian chronology) with the political unification of Upper and Lower Egypt under Menes (often identified with Narmer). The history of ancient Egypt occurred as a series of stable kingdoms, separated by periods of relative instability known as Intermediate Periods: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age. Egypt reached the pinnacle of its power in the New Kingdom, ruling much of Nubia and a sizable portion of the Near East, after which it entered a period of slow decline. During the course of its history Egypt was invaded or conquered by a number of foreign powers, including the Hyksos, the Libyans, the Nubians, the Assyrians, the Achaemenid Persians, and the Macedonians under the command of Alexander the Great. The Greek Ptolemaic Kingdom, formed in the aftermath of Alexander's death, ruled Egypt until 30BC, when, under Cleopatra, it fell to the Roman Empire and became a Roman province. The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system, the organization of collective construction and agricultural projects, trade with surrounding regions, and a military intended to assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes, religious leaders, and administrators under the control of a pharaoh, who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs. The many achievements of the ancient Egyptians include the quarrying, surveying and construction techniques that supported the building of monumental pyramids, temples, and obelisks; a system of mathematics, a practical and effective system of medicine, irrigation systems and agricultural production techniques, the first known planked boats, Egyptian faience and glass technology, new forms of literature, and the earliest known peace treaty, made with the Hittites. Ancient Egypt has left a lasting legacy. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world. Its monumental ruins have inspired the imaginations of travelers and writers for millennia. A newfound respect for antiquities and excavations in the early modern period by Europeans and Egyptians led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy. History The Nile has been the lifeline of its region for much of human history. The fertile floodplain of the Nile gave humans the opportunity to develop a settled agricultural economy and a more sophisticated, centralized society that became a cornerstone in the history of human civilization. Nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the arid climate of Northern Africa became increasingly hot and dry, forcing the populations of the area to concentrate along the river region. Predynastic period In Predynastic and Early Dynastic times, the Egyptian climate was much less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates. Foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated. By about 5500 BC, small tribes living in the Nile valley had developed into a series of cultures demonstrating firm control of agriculture and animal husbandry, and identifiable by their pottery and personal items, such as combs, bracelets, and beads. The largest of these early cultures in upper (Southern) Egypt was the Badarian culture, which probably originated in the Western Desert; it was known for its high-quality ceramics, stone tools, and its use of copper. The Badari was followed by the Naqada culture: the Amratian (Naqada I), the Gerzeh (Naqada II), and Semainean (Naqada III). These brought a number of technological improvements. As early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East, particularly Canaan and the Byblos coast. Over a period of about 1,000 years, the Naqada culture developed from a few small farming communities into a powerful civilization whose leaders were in complete control of the people and resources of the Nile valley. Establishing a power center at Nekhen (in Greek, Hierakonpolis), and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile. They also traded with Nubia to the south, the oases of the western desert to the west, and the cultures of the eastern Mediterranean and Near East to the east, initiating a period of Egypt-Mesopotamia relations. The Naqada culture manufactured a diverse selection of material goods, reflective of the increasing power and wealth of the elite, as well as societal personal-use items, which included combs, small statuary, painted pottery, high quality decorative stone vases, cosmetic palettes, and jewelry made of gold, lapis, and ivory. They also developed a ceramic glaze known as faience, which was used well into the Roman Period to decorate cups, amulets, and figurines. During the last predynastic phase, the Naqada culture began using written symbols that eventually were developed into a full system of hieroglyphs for writing the ancient Egyptian language. Early Dynastic Period (c. 3150–2686 BC) The Early Dynastic Period was approximately contemporary to the early Sumerian-Akkadian civilisation of Mesopotamia and of ancient Elam. The third-centuryBC Egyptian priest Manetho grouped the long line of kings from Menes to his own time into 30 dynasties, a system still used today. He began his official history with the king named "Meni" (or Menes in Greek), who was believed to have united the two kingdoms of Upper and Lower Egypt. The transition to a unified state happened more gradually than ancient Egyptian writers represented, and there is no contemporary record of Menes. Some scholars now believe, however, that the mythical Menes may have been the king Narmer, who is depicted wearing royal regalia on the ceremonial Narmer Palette, in a symbolic act of unification. In the Early Dynastic Period, which began about 3000BC, the first of the Dynastic kings solidified control over lower Egypt by establishing a capital at Memphis, from which he could control the labour force and agriculture of the fertile delta region, as well as the lucrative and critical trade routes to the Levant. The increasing power and wealth of the kings during the early dynastic period was reflected in their elaborate mastaba tombs and mortuary cult structures at Abydos, which were used to celebrate the deified king after his death. The strong institution of kingship developed by the kings served to legitimize state control over the land, labour, and resources that were essential to the survival and growth of ancient Egyptian civilization. Old Kingdom (2686–2181 BC) Major advances in architecture, art, and technology were made during the Old Kingdom, fueled by the increased agricultural productivity and resulting population, made possible by a well-developed central administration. Some of ancient Egypt's crowning achievements, the Giza pyramids and Great Sphinx, were constructed during the Old Kingdom. Under the direction of the vizier, state officials collected taxes, coordinated irrigation projects to improve crop yield, drafted peasants to work on construction projects, and established a justice system to maintain peace and order. With the rising importance of central administration in Egypt, a new class of educated scribes and officials arose who were granted estates by the king in payment for their services. Kings also made land grants to their mortuary cults and local temples, to ensure that these institutions had the resources to worship the king after his death. Scholars believe that five centuries of these practices slowly eroded the economic vitality of Egypt, and that the economy could no longer afford to support a large centralized administration. As the power of the kings diminished, regional governors called nomarchs began to challenge the supremacy of the office of king. This, coupled with severe droughts between 2200 and 2150BC, is believed to have caused the country to enter the 140-year period of famine and strife known as the First Intermediate Period. First Intermediate Period (2181–2055 BC) After Egypt's central government collapsed at the end of the Old Kingdom, the administration could no longer support or stabilize the country's economy. Regional governors could not rely on the king for help in times of crisis, and the ensuing food shortages and political disputes escalated into famines and small-scale civil wars. Yet despite difficult problems, local leaders, owing no tribute to the king, used their new-found independence to establish a thriving culture in the provinces. Once in control of their own resources, the provinces became economically richer—which was demonstrated by larger and better burials among all social classes. In bursts of creativity, provincial artisans adopted and adapted cultural motifs formerly restricted to the royalty of the Old Kingdom, and scribes developed literary styles that expressed the optimism and originality of the period. Free from their loyalties to the king, local rulers began competing with each other for territorial control and political power. By 2160BC, rulers in Herakleopolis controlled Lower Egypt in the north, while a rival clan based in Thebes, the Intef family, took control of Upper Egypt in the south. As the Intefs grew in power and expanded their control northward, a clash between the two rival dynasties became inevitable. Around 2055BC the northern Theban forces under Nebhepetre Mentuhotep II finally defeated the Herakleopolitan rulers, reuniting the Two Lands. They inaugurated a period of economic and cultural renaissance known as the Middle Kingdom. Middle Kingdom (2134–1690 BC) The kings of the Middle Kingdom restored the country's stability and prosperity, thereby stimulating a resurgence of art, literature, and monumental building projects. Mentuhotep II and his Eleventh Dynasty successors ruled from Thebes, but the vizier Amenemhat I, upon assuming the kingship at the beginning of the Twelfth Dynasty around 1985BC, shifted the kingdom's capital to the city of Itjtawy, located in Faiyum. From Itjtawy, the kings of the Twelfth Dynasty undertook a far-sighted land reclamation and irrigation scheme to increase agricultural output in the region. Moreover, the military reconquered territory in Nubia that was rich in quarries and gold mines, while laborers built a defensive structure in the Eastern Delta, called the "Walls of the Ruler", to defend against foreign attack. With the kings having secured the country militarily and politically and with vast agricultural and mineral wealth at their disposal, the nation's population, arts, and religion flourished. In contrast to elitist Old Kingdom attitudes towards the gods, the Middle Kingdom displayed an increase in expressions of personal piety. Middle Kingdom literature featured sophisticated themes and characters written in a confident, eloquent style. The relief and portrait sculpture of the period captured subtle, individual details that reached new heights of technical sophistication. The last great ruler of the Middle Kingdom, Amenemhat III, allowed Semitic-speaking Canaanite settlers from the Near East into the Delta region to provide a sufficient labour force for his especially active mining and building campaigns. These ambitious building and mining activities, however, combined with severe Nile floods later in his reign, strained the economy and precipitated the slow decline into the Second Intermediate Period during the later Thirteenth and Fourteenth dynasties. During this decline, the Canaanite settlers began to assume greater control of the Delta region, eventually coming to power in Egypt as the Hyksos. Second Intermediate Period (1674–1549 BC) and the Hyksos Around 1785BC, as the power of the Middle Kingdom kings weakened, a Western Asian people called the Hyksos, who had already settled in the Delta, seized control of Egypt and established their capital at Avaris, forcing the former central government to retreat to Thebes. The king was treated as a vassal and expected to pay tribute. The Hyksos ("foreign rulers") retained Egyptian models of government and identified as kings, thereby integrating Egyptian elements into their culture. They and other invaders introduced new tools of warfare into Egypt, most notably the composite bow and the horse-drawn chariot. After retreating south, the native Theban kings found themselves trapped between the Canaanite Hyksos ruling the north and the Hyksos' Nubian allies, the Kushites, to the south. After years of vassalage, Thebes gathered enough strength to challenge the Hyksos in a conflict that lasted more than 30 years, until 1555BC. The kings Seqenenre Tao II and Kamose were ultimately able to defeat the Nubians to the south of Egypt, but failed to defeat the Hyksos. That task fell to Kamose's successor, Ahmose I, who successfully waged a series of campaigns that permanently eradicated the Hyksos' presence in Egypt. He established a new dynasty and, in the New Kingdom that followed, the military became a central priority for the kings, who sought to expand Egypt's borders and attempted to gain mastery of the Near East. New Kingdom (1549–1069 BC) The New Kingdom pharaohs established a period of unprecedented prosperity by securing their borders and strengthening diplomatic ties with their neighbours, including the Mitanni Empire, Assyria, and Canaan. Military campaigns waged under Tuthmosis I and his grandson Tuthmosis III extended the influence of the pharaohs to the largest empire Egypt had ever seen. Beginning with Merneptah the rulers of Egypt adopted the title of pharaoh. Between their reigns, Hatshepsut, a queen who established herself as pharaoh, launched many building projects, including the restoration of temples damaged by the Hyksos, and sent trading expeditions to Punt and the Sinai. When Tuthmosis III died in 1425BC, Egypt had an empire extending from Niya in north west Syria to the Fourth Cataract of the Nile in Nubia, cementing loyalties and opening access to critical imports such as bronze and wood. The New Kingdom pharaohs began a large-scale building campaign to promote the god Amun, whose growing cult was based in Karnak. They also constructed monuments to glorify their own achievements, both real and imagined. The Karnak temple is the largest Egyptian temple ever built. Around 1350BC, the stability of the New Kingdom was threatened when Amenhotep IV ascended the throne and instituted a series of radical and chaotic reforms. Changing his name to Akhenaten, he touted the previously obscure sun deity Aten as the supreme deity, suppressed the worship of most other deities, and moved the capital to the new city of Akhetaten (modern-day Amarna). He was devoted to his new religion and artistic style. After his death, the cult of the Aten was quickly abandoned and the traditional religious order restored. The subsequent pharaohs, Tutankhamun, Ay, and Horemheb, worked to erase all mention of Akhenaten's heresy, now known as the Amarna Period. Around 1279BC, Ramesses II, also known as Ramesses the Great, ascended the throne, and went on to build more temples, erect more statues and obelisks, and sire more children than any other pharaoh in history. A bold military leader, Ramesses II led his army against the Hittites in the Battle of Kadesh (in modern Syria) and, after fighting to a stalemate, finally agreed to the first recorded peace treaty, around 1258BC. Egypt's wealth, however, made it a tempting target for invasion, particularly by the Libyan Berbers to the west, and the Sea Peoples, a conjectured confederation of seafarers from the Aegean Sea. Initially, the military was able to repel these invasions, but Egypt eventually lost control of its remaining territories in southern Canaan, much of it falling to the Assyrians. The effects of external threats were exacerbated by internal problems such as corruption, tomb robbery, and civil unrest. After regaining their power, the high priests at the temple of Amun in Thebes accumulated vast tracts of land and wealth, and their expanded power splintered the country during the Third Intermediate Period. Third Intermediate Period (1069–653 BC) Following the death of Ramesses XI in 1078BC, Smendes assumed authority over the northern part of Egypt, ruling from the city of Tanis. The south was effectively controlled by the High Priests of Amun at Thebes, who recognized Smendes in name only. During this time, Libyans had been settling in the western delta, and chieftains of these settlers began increasing their autonomy. Libyan princes took control of the delta under Shoshenq I in 945BC, founding the so-called Libyan or Bubastite dynasty that would rule for some 200 years. Shoshenq also gained control of southern Egypt by placing his family members in important priestly positions. Libyan control began to erode as a rival dynasty in the delta arose in Leontopolis, and Kushites threatened from the south. Around 727BC the Kushite king Piye invaded northward, seizing control of Thebes and eventually the Delta, which established the 25th Dynasty. During the 25th Dynasty, Pharaoh Taharqa created an empire nearly as large as the New Kingdom's. Twenty-fifth Dynasty pharaohs built, or restored, temples and monuments throughout the Nile valley, including at Memphis, Karnak, Kawa, and Jebel Barkal. During this period, the Nile valley saw the first widespread construction of pyramids (many in modern Sudan) since the Middle Kingdom. Egypt's far-reaching prestige declined considerably toward the end of the Third Intermediate Period. Its foreign allies had fallen under the Assyrian sphere of influence, and by 700BC war between the two states became inevitable. Between 671 and 667BC the Assyrians began the Assyrian conquest of Egypt. The reigns of both Taharqa and his successor, Tanutamun, were filled with constant conflict with the Assyrians, against whom Egypt enjoyed several victories. Ultimately, the Assyrians pushed the Kushites back into Nubia, occupied Memphis, and sacked the temples of Thebes. Late Period (653–332 BC) The Assyrians left control of Egypt to a series of vassals who became known as the Saite kings of the Twenty-Sixth Dynasty. By 653BC, the Saite king Psamtik I was able to oust the Assyrians with the help of Greek mercenaries, who were recruited to form Egypt's first navy. Greek influence expanded greatly as the city-state of Naukratis became the home of Greeks in the Nile Delta. The Saite kings based in the new capital of Sais witnessed a brief but spirited resurgence in the economy and culture, but in 525BC, the powerful Persians, led by Cambyses II, began their conquest of Egypt, eventually capturing the pharaoh Psamtik III at the Battle of Pelusium. Cambyses II then assumed the formal title of pharaoh, but ruled Egypt from Iran, leaving Egypt under the control of a satrap. A few successful revolts against the Persians marked the 5th centuryBC, but Egypt was never able to permanently overthrow the Persians. Following its annexation by Persia, Egypt was joined with Cyprus and Phoenicia in the sixth satrapy of the Achaemenid Persian Empire. This first period of Persian rule over Egypt, also known as the Twenty-Seventh Dynasty, ended in 402BC, when Egypt regained independence under a series of native dynasties. The last of these dynasties, the Thirtieth, proved to be the last native royal house of ancient Egypt, ending with the kingship of Nectanebo II. A brief restoration of Persian rule, sometimes known as the Thirty-First Dynasty, began in 343BC, but shortly after, in 332BC, the Persian ruler Mazaces handed Egypt over to Alexander the Great without a fight. Ptolemaic period (332–30 BC) In 332BC, Alexander the Great conquered Egypt with little resistance from the Persians and was welcomed by the Egyptians as a deliverer. The administration established by Alexander's successors, the Macedonian Ptolemaic Kingdom, was based on an Egyptian model and based in the new capital city of Alexandria. The city showcased the power and prestige of Hellenistic rule, and became a seat of learning and culture, centered at the famous Library of Alexandria. The Lighthouse of Alexandria lit the way for the many ships that kept trade flowing through the city—as the Ptolemies made commerce and revenue-generating enterprises, such as papyrus manufacturing, their top priority. Hellenistic culture did not supplant native Egyptian culture, as the Ptolemies supported time-honored traditions in an effort to secure the loyalty of the populace. They built new temples in Egyptian style, supported traditional cults, and portrayed themselves as pharaohs. Some traditions merged, as Greek and Egyptian gods were syncretized into composite deities, such as Serapis, and classical Greek forms of sculpture influenced traditional Egyptian motifs. Despite their efforts to appease the Egyptians, the Ptolemies were challenged by native rebellion, bitter family rivalries, and the powerful mob of Alexandria that formed after the death of Ptolemy IV. In addition, as Rome relied more heavily on imports of grain from Egypt, the Romans took great interest in the political situation in the country. Continued Egyptian revolts, ambitious politicians, and powerful opponents from the Near East made this situation unstable, leading Rome to send forces to secure the country as a province of its empire. Roman period (30 BC – AD 641) Egypt became a province of the Roman Empire in 30BC, following the defeat of Mark Antony and Ptolemaic Queen Cleopatra VII by Octavian (later Emperor Augustus) in the Battle of Actium. The Romans relied heavily on grain shipments from Egypt, and the Roman army, under the control of a prefect appointed by the emperor, quelled rebellions, strictly enforced the collection of heavy taxes, and prevented attacks by bandits, which had become a notorious problem during the period. Alexandria became an increasingly important center on the trade route with the orient, as exotic luxuries were in high demand in Rome. Although the Romans had a more hostile attitude than the Greeks towards the Egyptians, some traditions such as mummification and worship of the traditional gods continued. The art of mummy portraiture flourished, and some Roman emperors had themselves depicted as pharaohs, though not to the extent that the Ptolemies had. The former lived outside Egypt and did not perform the ceremonial functions of Egyptian kingship. Local administration became Roman in style and closed to native Egyptians. From the mid-first century AD, Christianity took root in Egypt and it was originally seen as another cult that could be accepted. However, it was an uncompromising religion that sought to win converts from the pagan Egyptian and Greco-Roman religions and threatened popular religious traditions. This led to the persecution of converts to Christianity, culminating in the great purges of Diocletian starting in 303, but eventually Christianity won out. In 391 the Christian emperor Theodosius introduced legislation that banned pagan rites and closed temples. Alexandria became the scene of great anti-pagan riots with public and private religious imagery destroyed. As a consequence, Egypt's native religious culture was continually in decline. While the native population continued to speak their language, the ability to read hieroglyphic writing slowly disappeared as the role of the Egyptian temple priests and priestesses diminished. The temples themselves were sometimes converted to churches or abandoned to the desert. In the fourth century, as the Roman Empire divided, Egypt found itself in the Eastern Empire with its capital at Constantinople. In the waning years of the Empire, Egypt fell to the Sasanian Persian army in the Sasanian conquest of Egypt (618–628). It was then recaptured by the Byzantine emperor Heraclius (629–639), and was finally captured by Muslim Rashidun army in 639–641, ending Byzantine rule. Government and economy Administration and commerce The pharaoh was the absolute monarch of the country and, at least in theory, wielded complete control of the land and its resources. The king was the supreme military commander and head of the government, who relied on a bureaucracy of officials to manage his affairs. In charge of the administration was his second in command, the vizier, who acted as the king's representative and coordinated land surveys, the treasury, building projects, the legal system, and the archives. At a regional level, the country was divided into as many as 42 administrative regions called nomes each governed by a nomarch, who was accountable to the vizier for his jurisdiction. The temples formed the backbone of the economy. Not only were they places of worship, but were also responsible for collecting and storing the kingdom's wealth in a system of granaries and treasuries administered by overseers, who redistributed grain and goods. Much of the economy was centrally organized and strictly controlled. Although the ancient Egyptians did not use coinage until the Late period, they did use a type of money-barter system, with standard sacks of grain and the deben, a weight of roughly of copper or silver, forming a common denominator. Workers were paid in grain; a simple laborer might earn 5 sacks (200 kg or 400 lb) of grain per month, while a foreman might earn 7 sacks (250 kg or 550 lb). Prices were fixed across the country and recorded in lists to facilitate trading; for example a shirt cost five copper deben, while a cow cost 140deben. Grain could be traded for other goods, according to the fixed price list. During the fifth centuryBC coined money was introduced into Egypt from abroad. At first the coins were used as standardized pieces of precious metal rather than true money, but in the following centuries international traders came to rely on coinage. Social status Egyptian society was highly stratified, and social status was expressly displayed. Farmers made up the bulk of the population, but agricultural produce was owned directly by the state, temple, or noble family that owned the land. Farmers were also subject to a labor tax and were required to work on irrigation or construction projects in a corvée system. Artists and craftsmen were of higher status than farmers, but they were also under state control, working in the shops attached to the temples and paid directly from the state treasury. Scribes and officials formed the upper class in ancient Egypt, known as the "white kilt class" in reference to the bleached linen garments that served as a mark of their rank. The upper class prominently displayed their social status in art and literature. Below the nobility were the priests, physicians, and engineers with specialized training in their field. It is unclear whether slavery as understood today existed in ancient Egypt; there is difference of opinions among authors. The ancient Egyptians viewed men and women, including people from all social classes, as essentially equal under the law, and even the lowliest peasant was entitled to petition the vizier and his court for redress. Although slaves were mostly used as indentured servants, they were able to buy and sell their servitude, work their way to freedom or nobility, and were usually treated by doctors in the workplace. Both men and women had the right to own and sell property, make contracts, marry and divorce, receive inheritance, and pursue legal disputes in court. Married couples could own property jointly and protect themselves from divorce by agreeing to marriage contracts, which stipulated the financial obligations of the husband to his wife and children should the marriage end. Compared with their counterparts in ancient Greece, Rome, and even more modern places around the world, ancient Egyptian women had a greater range of personal choices, legal rights, and opportunities for achievement. Women such as Hatshepsut and Cleopatra VII even became pharaohs, while others wielded power as Divine Wives of Amun. Despite these freedoms, ancient Egyptian women did not often take part in official roles in the administration, aside from the royal high priestesses, apparently served only secondary roles in the temples (not much data for many dynasties), and were not so likely to be as educated as men. Legal system The head of the legal system was officially the pharaoh, who was responsible for enacting laws, delivering justice, and maintaining law and order, a concept the ancient Egyptians referred to as Ma'at. Although no legal codes from ancient Egypt survive, court documents show that Egyptian law was based on a common-sense view of right and wrong that emphasized reaching agreements and resolving conflicts rather than strictly adhering to a complicated set of statutes. Local councils of elders, known as Kenbet in the New Kingdom, were responsible for ruling in court cases involving small claims and minor disputes. More serious cases involving murder, major land transactions, and tomb robbery were referred to the Great Kenbet, over which the vizier or pharaoh presided. Plaintiffs and defendants were expected to represent themselves and were required to swear an oath that they had told the truth. In some cases, the state took on both the role of prosecutor and judge, and it could torture the accused with beatings to obtain a confession and the names of any co-conspirators. Whether the charges were trivial or serious, court scribes documented the complaint, testimony, and verdict of the case for future reference. Punishment for minor crimes involved either imposition of fines, beatings, facial mutilation, or exile, depending on the severity of the offense. Serious crimes such as murder and tomb robbery were punished by execution, carried out by decapitation, drowning, or impaling the criminal on a stake. Punishment could also be extended to the criminal's family. Beginning in the New Kingdom, oracles played a major role in the legal system, dispensing justice in both civil and criminal cases. The procedure was to ask the god a "yes" or "no" question concerning the right or wrong of an issue. The god, carried by a number of priests, rendered judgement by choosing one or the other, moving forward or backward, or pointing to one of the answers written on a piece of papyrus or an ostracon. Agriculture A combination of favorable geographical features contributed to the success of ancient Egyptian culture, the most important of which was the rich fertile soil resulting from annual inundations of the Nile River. The ancient Egyptians were thus able to produce an abundance of food, allowing the population to devote more time and resources to cultural, technological, and artistic pursuits. Land management was crucial in ancient Egypt because taxes were assessed based on the amount of land a person owned. Farming in Egypt was dependent on the cycle of the Nile River. The Egyptians recognized three seasons: Akhet (flooding), Peret (planting), and Shemu (harvesting). The flooding season lasted from June to September, depositing on the river's banks a layer of mineral-rich silt ideal for growing crops. After the floodwaters had receded, the growing season lasted from October to February. Farmers plowed and planted seeds in the fields, which were irrigated with ditches and canals. Egypt received little rainfall, so farmers relied on the Nile to water their crops. From March to May, farmers used sickles to harvest their crops, which were then threshed with a flail to separate the straw from the grain. Winnowing removed the chaff from the grain, and the grain was then ground into flour, brewed to make beer, or stored for later use. The ancient Egyptians cultivated emmer and barley, and several other cereal grains, all of which were used to make the two main food staples of bread and beer. Flax plants, uprooted before they started flowering, were grown for the fibers of their stems. These fibers were split along their length and spun into thread, which was used to weave sheets of linen and to make clothing. Papyrus growing on the banks of the Nile River was used to make paper. Vegetables and fruits were grown in garden plots, close to habitations and on higher ground, and had to be watered by hand. Vegetables included leeks, garlic, melons, squashes, pulses, lettuce, and other crops, in addition to grapes that were made into wine. Animals The Egyptians believed that a balanced relationship between people and animals was an essential element of the cosmic order; thus humans, animals and plants were believed to be members of a single whole. Animals, both domesticated and wild, were therefore a critical source of spirituality, companionship, and sustenance to the ancient Egyptians. Cattle were the most important livestock; the administration collected taxes on livestock in regular censuses, and the size of a herd reflected the prestige and importance of the estate or temple that owned them. In addition to cattle, the ancient Egyptians kept sheep, goats, and pigs. Poultry, such as ducks, geese, and pigeons, were captured in nets and bred on farms, where they were force-fed with dough to fatten them. The Nile provided a plentiful source of fish. Bees were also domesticated from at least the Old Kingdom, and provided both honey and wax. The ancient Egyptians used donkeys and oxen as beasts of burden, and they were responsible for plowing the fields and trampling seed into the soil. The slaughter of a fattened ox was also a central part of an offering ritual. Horses were introduced by the Hyksos in the Second Intermediate Period. Camels, although known from the New Kingdom, were not used as beasts of burden until the Late Period. There is also evidence to suggest that elephants were briefly utilized in the Late Period but largely abandoned due to lack of grazing land. Cats, dogs, and monkeys were common family pets, while more exotic pets imported from the heart of Africa, such as Sub-Saharan African lions, were reserved for royalty. Herodotus observed that the Egyptians were the only people to keep their animals with them in their houses. During the Late Period, the worship of the gods in their animal form was extremely popular, such as the cat goddess Bastet and the ibis god Thoth, and these animals were kept in large numbers for the purpose of ritual sacrifice. Natural resources Egypt is rich in building and decorative stone, copper and lead ores, gold, and semiprecious stones. These natural resources allowed the ancient Egyptians to build monuments, sculpt statues, make tools, and fashion jewelry. Embalmers used salts from the Wadi Natrun for mummification, which also provided the gypsum needed to make plaster. Ore-bearing rock formations were found in distant, inhospitable wadis in the Eastern Desert and the Sinai, requiring large, state-controlled expeditions to obtain natural resources found there. There were extensive gold mines in Nubia, and one of the first maps known is of a gold mine in this region. The Wadi Hammamat was a notable source of granite, greywacke, and gold. Flint was the first mineral collected and used to make tools, and flint handaxes are the earliest pieces of evidence of habitation in the Nile valley. Nodules of the mineral were carefully flaked to make blades and arrowheads of moderate hardness and durability even after copper was adopted for this purpose. Ancient Egyptians were among the first to use minerals such as sulfur as cosmetic substances. The Egyptians worked deposits of the lead ore galena at Gebel Rosas to make net sinkers, plumb bobs, and small figurines. Copper was the most important metal for toolmaking in ancient Egypt and was smelted in furnaces from malachite ore mined in the Sinai. Workers collected gold by washing the nuggets out of sediment in alluvial deposits, or by the more labor-intensive process of grinding and washing gold-bearing quartzite. Iron deposits found in upper Egypt were utilized in the Late Period. High-quality building stones were abundant in Egypt; the ancient Egyptians quarried limestone all along the Nile valley, granite from Aswan, and basalt and sandstone from the wadis of the Eastern Desert. Deposits of decorative stones such as porphyry, greywacke, alabaster, and carnelian dotted the Eastern Desert and were collected even before the First Dynasty. In the Ptolemaic and Roman Periods, miners worked deposits of emeralds in Wadi Sikait and amethyst in Wadi el-Hudi. Trade The ancient Egyptians engaged in trade with their foreign neighbors to obtain rare, exotic goods not found in Egypt. In the Predynastic Period, they established trade with Nubia to obtain gold and incense. They also established trade with Palestine, as evidenced by Palestinian-style oil jugs found in the burials of the First Dynasty pharaohs. An Egyptian colony stationed in southern Canaan dates to slightly before the First Dynasty. Narmer had Egyptian pottery produced in Canaan and exported back to Egypt. By the Second Dynasty at latest, ancient Egyptian trade with Byblos yielded a critical source of quality timber not found in Egypt. By the Fifth Dynasty, trade with Punt provided gold, aromatic resins, ebony, ivory, and wild animals such as monkeys and baboons. Egypt relied on trade with Anatolia for essential quantities of tin as well as supplementary supplies of copper, both metals being necessary for the manufacture of bronze. The ancient Egyptians prized the blue stone lapis lazuli, which had to be imported from far-away Afghanistan. Egypt's Mediterranean trade partners also included Greece and Crete, which provided, among other goods, supplies of olive oil. Language Historical development The Egyptian language is a northern Afro-Asiatic language closely related to the Berber and Semitic languages. It has the second longest known history of any language (after Sumerian), having been written from c. 3200BC to the Middle Ages and remaining as a spoken language for longer. The phases of ancient Egyptian are Old Egyptian, Middle Egyptian (Classical Egyptian), Late Egyptian, Demotic and Coptic. Egyptian writings do not show dialect differences before Coptic, but it was probably spoken in regional dialects around Memphis and later Thebes. Ancient Egyptian was a synthetic language, but it became more analytic later on. Late Egyptian developed prefixal definite and indefinite articles, which replaced the older inflectional suffixes. There was a change from the older verb–subject–object word order to subject–verb–object. The Egyptian hieroglyphic, hieratic, and demotic scripts were eventually replaced by the more phonetic Coptic alphabet. Coptic is still used in the liturgy of the Egyptian Orthodox Church, and traces of it are found in modern Egyptian Arabic. Sounds and grammar Ancient Egyptian has 25 consonants similar to those of other Afro-Asiatic languages. These include pharyngeal and emphatic consonants, voiced and voiceless stops, voiceless fricatives and voiced and voiceless affricates. It has three long and three short vowels, which expanded in Late Egyptian to about nine. The basic word in Egyptian, similar to Semitic and Berber, is a triliteral or biliteral root of consonants and semiconsonants. Suffixes are added to form words. The verb conjugation corresponds to the person. For example, the triconsonantal skeleton is the semantic core of the word 'hear'; its basic conjugation is , 'he hears'. If the subject is a noun, suffixes are not added to the verb: , 'the woman hears'. Adjectives are derived from nouns through a process that Egyptologists call nisbation because of its similarity with Arabic. The word order is in verbal and adjectival sentences, and in nominal and adverbial sentences. The subject can be moved to the beginning of sentences if it is long and is followed by a resumptive pronoun. Verbs and nouns are negated by the particle n, but nn is used for adverbial and adjectival sentences. Stress falls on the ultimate or penultimate syllable, which can be open (CV) or closed (CVC). Writing Hieroglyphic writing dates from c. 3000BC, and is composed of hundreds of symbols. A hieroglyph can represent a word, a sound, or a silent determinative; and the same symbol can serve different purposes in different contexts. Hieroglyphs were a formal script, used on stone monuments and in tombs, that could be as detailed as individual works of art. In day-to-day writing, scribes used a cursive form of writing, called hieratic, which was quicker and easier. While formal hieroglyphs may be read in rows or columns in either direction (though typically written from right to left), hieratic was always written from right to left, usually in horizontal rows. A new form of writing, Demotic, became the prevalent writing style, and it is this form of writing—along with formal hieroglyphs—that accompany the Greek text on the Rosetta Stone. Around the first century AD, the Coptic alphabet started to be used alongside the Demotic script. Coptic is a modified Greek alphabet with the addition of some Demotic signs. Although formal hieroglyphs were used in a ceremonial role until the fourth century, towards the end only a small handful of priests could still read them. As the traditional religious establishments were disbanded, knowledge of hieroglyphic writing was mostly lost. Attempts to decipher them date to the Byzantine and Islamic periods in Egypt, but only in the 1820s, after the discovery of the Rosetta Stone and years of research by Thomas Young and Jean-François Champollion, were hieroglyphs substantially deciphered. Literature Writing first appeared in association with kingship on labels and tags for items found in royal tombs. It was primarily an occupation of the scribes, who worked out of the Per Ankh institution or the House of Life. The latter comprised offices, libraries (called House of Books), laboratories and observatories. Some of the best-known pieces of ancient Egyptian literature, such as the Pyramid and Coffin Texts, were written in Classical Egyptian, which continued to be the language of writing until about 1300BC. Late Egyptian was spoken from the New Kingdom onward and is represented in Ramesside administrative documents, love poetry and tales, as well as in Demotic and Coptic texts. During this period, the tradition of writing had evolved into the tomb autobiography, such as those of Harkhuf and Weni. The genre known as Sebayt ("instructions") was developed to communicate teachings and guidance from famous nobles; the Ipuwer papyrus, a poem of lamentations describing natural disasters and social upheaval, is a famous example. The Story of Sinuhe, written in Middle Egyptian, might be the classic of Egyptian literature. Also written at this time was the Westcar Papyrus, a set of stories told to Khufu by his sons relating the marvels performed by priests. The Instruction of Amenemope is considered a masterpiece of Near Eastern literature. Towards the end of the New Kingdom, the vernacular language was more often employed to write popular pieces like the Story of Wenamun and the Instruction of Any. The former tells the story of a noble who is robbed on his way to buy cedar from Lebanon and of his struggle to return to Egypt. From about 700BC, narrative stories and instructions, such as the popular Instructions of Onchsheshonqy, as well as personal and business documents were written in the demotic script and phase of Egyptian. Many stories written in demotic during the Greco-Roman period were set in previous historical eras, when Egypt was an independent nation ruled by great pharaohs such as Ramesses II. Culture Daily life Most ancient Egyptians were farmers tied to the land. Their dwellings were restricted to immediate family members, and were constructed of mudbrick designed to remain cool in the heat of the day. Each home had a kitchen with an open roof, which contained a grindstone for milling grain and a small oven for baking the bread. Ceramics served as household wares for the storage, preparation, transport, and consumption of food, drink, and raw materials. Walls were painted white and could be covered with dyed linen wall hangings. Floors were covered with reed mats, while wooden stools, beds raised from the floor and individual tables comprised the furniture. The ancient Egyptians placed a great value on hygiene and appearance. Most bathed in the Nile and used a pasty soap made from animal fat and chalk. Men shaved their entire bodies for cleanliness; perfumes and aromatic ointments covered bad odors and soothed skin. Clothing was made from simple linen sheets that were bleached white, and both men and women of the upper classes wore wigs, jewelry, and cosmetics. Children went without clothing until maturity, at about age 12, and at this age males were circumcised and had their heads shaved. Mothers were responsible for taking care of the children, while the father provided the family's income. Music and dance were popular entertainments for those who could afford them. Early instruments included flutes and harps, while instruments similar to trumpets, oboes, and pipes developed later and became popular. In the New Kingdom, the Egyptians played on bells, cymbals, tambourines, drums, and imported lutes and lyres from Asia. The sistrum was a rattle-like musical instrument that was especially important in religious ceremonies. The ancient Egyptians enjoyed a variety of leisure activities, including games and music. Senet, a board game where pieces moved according to random chance, was particularly popular from the earliest times; another similar game was mehen, which had a circular gaming board. “Hounds and Jackals” also known as 58 holes is another example of board games played in ancient Egypt. The first complete set of this game was discovered from a Theban tomb of the Egyptian pharaoh Amenemhat IV that dates to the 13th Dynasty. Juggling and ball games were popular with children, and wrestling is also documented in a tomb at Beni Hasan. The wealthy members of ancient Egyptian society enjoyed hunting, fishing, and boating as well. The excavation of the workers' village of Deir el-Medina has resulted in one of the most thoroughly documented accounts of community life in the ancient world, which spans almost four hundred years. There is no comparable site in which the organization, social interactions, and working and living conditions of a community have been studied in such detail. Cuisine Egyptian cuisine remained remarkably stable over time; indeed, the cuisine of modern Egypt retains some striking similarities to the cuisine of the ancients. The staple diet consisted of bread and beer, supplemented with vegetables such as onions and garlic, and fruit such as dates and figs. Wine and meat were enjoyed by all on feast days while the upper classes indulged on a more regular basis. Fish, meat, and fowl could be salted or dried, and could be cooked in stews or roasted on a grill. Architecture The architecture of ancient Egypt includes some of the most famous structures in the world: the Great Pyramids of Giza and the temples at Thebes. Building projects were organized and funded by the state for religious and commemorative purposes, but also to reinforce the wide-ranging power of the pharaoh. The ancient Egyptians were skilled builders; using only simple but effective tools and sighting instruments, architects could build large stone structures with great accuracy and precision that is still envied today. The domestic dwellings of elite and ordinary Egyptians alike were constructed from perishable materials such as mudbricks and wood, and have not survived. Peasants lived in simple homes, while the palaces of the elite and the pharaoh were more elaborate structures. A few surviving New Kingdom palaces, such as those in Malkata and Amarna, show richly decorated walls and floors with scenes of people, birds, water pools, deities and geometric designs. Important structures such as temples and tombs that were intended to last forever were constructed of stone instead of mudbricks. The architectural elements used in the world's first large-scale stone building, Djoser's mortuary complex, include post and lintel supports in the papyrus and lotus motif. The earliest preserved ancient Egyptian temples, such as those at Giza, consist of single, enclosed halls with roof slabs supported by columns. In the New Kingdom, architects added the pylon, the open courtyard, and the enclosed hypostyle hall to the front of the temple's sanctuary, a style that was standard until the Greco-Roman period. The earliest and most popular tomb architecture in the Old Kingdom was the mastaba, a flat-roofed rectangular structure of mudbrick or stone built over an underground burial chamber. The step pyramid of Djoser is a series of stone mastabas stacked on top of each other. Pyramids were built during the Old and Middle Kingdoms, but most later rulers abandoned them in favor of less conspicuous rock-cut tombs. The use of the pyramid form continued in private tomb chapels of the New Kingdom and in the royal pyramids of Nubia. Art The ancient Egyptians produced art to serve functional purposes. For over 3500 years, artists adhered to artistic forms and iconography that were developed during the Old Kingdom, following a strict set of principles that resisted foreign influence and internal change. These artistic standards—simple lines, shapes, and flat areas of color combined with the characteristic flat projection of figures with no indication of spatial depth—created a sense of order and balance within a composition. Images and text were intimately interwoven on tomb and temple walls, coffins, stelae, and even statues. The Narmer Palette, for example, displays figures that can also be read as hieroglyphs. Because of the rigid rules that governed its highly stylized and symbolic appearance, ancient Egyptian art served its political and religious purposes with precision and clarity. Ancient Egyptian artisans used stone as a medium for carving statues and fine reliefs, but used wood as a cheap and easily carved substitute. Paints were obtained from minerals such as iron ores (red and yellow ochres), copper ores (blue and green), soot or charcoal (black), and limestone (white). Paints could be mixed with gum arabic as a binder and pressed into cakes, which could be moistened with water when needed. Pharaohs used reliefs to record victories in battle, royal decrees, and religious scenes. Common citizens had access to pieces of funerary art, such as shabti statues and books of the dead, which they believed would protect them in the afterlife. During the Middle Kingdom, wooden or clay models depicting scenes from everyday life became popular additions to the tomb. In an attempt to duplicate the activities of the living in the afterlife, these models show laborers, houses, boats, and even military formations that are scale representations of the ideal ancient Egyptian afterlife. Despite the homogeneity of ancient Egyptian art, the styles of particular times and places sometimes reflected changing cultural or political attitudes. After the invasion of the Hyksos in the Second Intermediate Period, Minoan-style frescoes were found in Avaris. The most striking example of a politically driven change in artistic forms comes from the Amarna Period, where figures were radically altered to conform to Akhenaten's revolutionary religious ideas. This style, known as Amarna art, was quickly abandoned after Akhenaten's death and replaced by the traditional forms. Religious beliefs Beliefs in the divine and in the afterlife were ingrained in ancient Egyptian civilization from its inception; pharaonic rule was based on the divine right of kings. The Egyptian pantheon was populated by gods who had supernatural powers and were called on for help or protection. However, the gods were not always viewed as benevolent, and Egyptians believed they had to be appeased with offerings and prayers. The structure of this pantheon changed continually as new deities were promoted in the hierarchy, but priests made no effort to organize the diverse and sometimes conflicting myths and stories into a coherent system. These various conceptions of divinity were not considered contradictory but rather layers in the multiple facets of reality. Gods were worshiped in cult temples administered by priests acting on the king's behalf. At the center of the temple was the cult statue in a shrine. Temples were not places of public worship or congregation, and only on select feast days and celebrations was a shrine carrying the statue of the god brought out for public worship. Normally, the god's domain was sealed off from the outside world and was only accessible to temple officials. Common citizens could worship private statues in their homes, and amulets offered protection against the forces of chaos. After the New Kingdom, the pharaoh's role as a spiritual intermediary was de-emphasized as religious customs shifted to direct worship of the gods. As a result, priests developed a system of oracles to communicate the will of the gods directly to the people. The Egyptians believed that every human being was composed of physical and spiritual parts or aspects. In addition to the body, each person had a šwt (shadow), a ba (personality or soul), a ka (life-force), and a name. The heart, rather than the brain, was considered the seat of thoughts and emotions. After death, the spiritual aspects were released from the body and could move at will, but they required the physical remains (or a substitute, such as a statue) as a permanent home. The ultimate goal of the deceased was to rejoin his ka and ba and become one of the "blessed dead", living on as an akh, or "effective one". For this to happen, the deceased had to be judged worthy in a trial, in which the heart was weighed against a "feather of truth." If deemed worthy, the deceased could continue their existence on earth in spiritual form. If they were not deemed worthy, their heart was eaten by Ammit the Devourer and they were erased from the Universe. Burial customs The ancient Egyptians maintained an elaborate set of burial customs that they believed were necessary to ensure immortality after death. These customs involved preserving the body by mummification, performing burial ceremonies, and interring with the body goods the deceased would use in the afterlife. Before the Old Kingdom, bodies buried in desert pits were naturally preserved by desiccation. The arid, desert conditions were a boon throughout the history of ancient Egypt for burials of the poor, who could not afford the elaborate burial preparations available to the elite. Wealthier Egyptians began to bury their dead in stone tombs and use artificial mummification, which involved removing the internal organs, wrapping the body in linen, and burying it in a rectangular stone sarcophagus or wooden coffin. Beginning in the Fourth Dynasty, some parts were preserved separately in canopic jars. By the New Kingdom, the ancient Egyptians had perfected the art of mummification; the best technique took 70 days and involved removing the internal organs, removing the brain through the nose, and desiccating the body in a mixture of salts called natron. The body was then wrapped in linen with protective amulets inserted between layers and placed in a decorated anthropoid coffin. Mummies of the Late Period were also placed in painted cartonnage mummy cases. Actual preservation practices declined during the Ptolemaic and Roman eras, while greater emphasis was placed on the outer appearance of the mummy, which was decorated. Wealthy Egyptians were buried with larger quantities of luxury items, but all burials, regardless of social status, included goods for the deceased. Funerary texts were often included in the grave, and, beginning in the New Kingdom, so were shabti statues that were believed to perform manual labor for them in the afterlife. Rituals in which the deceased was magically re-animated accompanied burials. After burial, living relatives were expected to occasionally bring food to the tomb and recite prayers on behalf of the deceased. Military The ancient Egyptian military was responsible for defending Egypt against foreign invasion, and for maintaining Egypt's domination in the ancient Near East. The military protected mining expeditions to the Sinai during the Old Kingdom and fought civil wars during the First and Second Intermediate Periods. The military was responsible for maintaining fortifications along important trade routes, such as those found at the city of Buhen on the way to Nubia. Forts also were constructed to serve as military bases, such as the fortress at Sile, which was a base of operations for expeditions to the Levant. In the New Kingdom, a series of pharaohs used the standing Egyptian army to attack and conquer Kush and parts of the Levant. Typical military equipment included bows and arrows, spears, and round-topped shields made by stretching animal skin over a wooden frame. In the New Kingdom, the military began using chariots that had earlier been introduced by the Hyksos invaders. Weapons and armor continued to improve after the adoption of bronze: shields were now made from solid wood with a bronze buckle, spears were tipped with a bronze point, and the khopesh was adopted from Asiatic soldiers. The pharaoh was usually depicted in art and literature riding at the head of the army; it has been suggested that at least a few pharaohs, such as Seqenenre Tao II and his sons, did do so. However, it has also been argued that "kings of this period did not personally act as frontline war leaders, fighting alongside their troops." Soldiers were recruited from the general population, but during, and especially after, the New Kingdom, mercenaries from Nubia, Kush, and Libya were hired to fight for Egypt. Technology, medicine, and mathematics Technology In technology, medicine, and mathematics, ancient Egypt achieved a relatively high standard of productivity and sophistication. Traditional empiricism, as evidenced by the Edwin Smith and Ebers papyri (c. 1600BC), is first credited to Egypt. The Egyptians created their own alphabet and decimal system. Faience and glass Even before the Old Kingdom, the ancient Egyptians had developed a glassy material known as faience, which they treated as a type of artificial semi-precious stone. Faience is a non-clay ceramic made of silica, small amounts of lime and soda, and a colorant, typically copper. The material was used to make beads, tiles, figurines, and small wares. Several methods can be used to create faience, but typically production involved application of the powdered materials in the form of a paste over a clay core, which was then fired. By a related technique, the ancient Egyptians produced a pigment known as Egyptian blue, also called blue frit, which is produced by fusing (or sintering) silica, copper, lime, and an alkali such as natron. The product can be ground up and used as a pigment. The ancient Egyptians could fabricate a wide variety of objects from glass with great skill, but it is not clear whether they developed the process independently. It is also unclear whether they made their own raw glass or merely imported pre-made ingots, which they melted and finished. However, they did have technical expertise in making objects, as well as adding trace elements to control the color of the finished glass. A range of colors could be produced, including yellow, red, green, blue, purple, and white, and the glass could be made either transparent or opaque. Medicine The medical problems of the ancient Egyptians stemmed directly from their environment. Living and working close to the Nile brought hazards from malaria and debilitating schistosomiasis parasites, which caused liver and intestinal damage. Dangerous wildlife such as crocodiles and hippos were also a common threat. The lifelong labors of farming and building put stress on the spine and joints, and traumatic injuries from construction and warfare all took a significant toll on the body. The grit and sand from stone-ground flour abraded teeth, leaving them susceptible to abscesses (though caries were rare). The diets of the wealthy were rich in sugars, which promoted periodontal disease. Despite the flattering physiques portrayed on tomb walls, the overweight mummies of many of the upper class show the effects of a life of overindulgence. Adult life expectancy was about 35 for men and 30 for women, but reaching adulthood was difficult as about one-third of the population died in infancy. Ancient Egyptian physicians were renowned in the ancient Near East for their healing skills, and some, such as Imhotep, remained famous long after their deaths. Herodotus remarked that there was a high degree of specialization among Egyptian physicians, with some treating only the head or the stomach, while others were eye-doctors and dentists. Training of physicians took place at the Per Ankh or "House of Life" institution, most notably those headquartered in Per-Bastet during the New Kingdom and at Abydos and Saïs in the Late period. Medical papyri show empirical knowledge of anatomy, injuries, and practical treatments. Wounds were treated by bandaging with raw meat, white linen, sutures, nets, pads, and swabs soaked with honey to prevent infection, while opium, thyme, and belladona were used to relieve pain. The earliest records of burn treatment describe burn dressings that use the milk from mothers of male babies. Prayers were made to the goddess Isis. Moldy bread, honey, and copper salts were also used to prevent infection from dirt in burns. Garlic and onions were used regularly to promote good health and were thought to relieve asthma symptoms. Ancient Egyptian surgeons stitched wounds, set broken bones, and amputated diseased limbs, but they recognized that some injuries were so serious that they could only make the patient comfortable until death occurred. Maritime technology Early Egyptians knew how to assemble planks of wood into a ship hull and had mastered advanced forms of shipbuilding as early as 3000BC. The Archaeological Institute of America reports that the oldest planked ships known are the Abydos boats. A group of 14 discovered ships in Abydos were constructed of wooden planks "sewn" together. Discovered by Egyptologist David O'Connor of New York University, woven straps were found to have been used to lash the planks together, and reeds or grass stuffed between the planks helped to seal the seams. Because the ships are all buried together and near a mortuary belonging to Pharaoh Khasekhemwy, originally they were all thought to have belonged to him, but one of the 14 ships dates to 3000BC, and the associated pottery jars buried with the vessels also suggest earlier dating. The ship dating to 3000BC was long and is now thought to perhaps have belonged to an earlier pharaoh, perhaps one as early as Hor-Aha. Early Egyptians also knew how to assemble planks of wood with treenails to fasten them together, using pitch for caulking the seams. The "Khufu ship", a vessel sealed into a pit in the Giza pyramid complex at the foot of the Great Pyramid of Giza in the Fourth Dynasty around 2500BC, is a full-size surviving example that may have filled the symbolic function of a solar barque. Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon joints. Large seagoing ships are known to have been heavily used by the Egyptians in their trade with the city states of the eastern Mediterranean, especially Byblos (on the coast of modern-day Lebanon), and in several expeditions down the Red Sea to the Land of Punt. In fact one of the earliest Egyptian words for a seagoing ship is a "Byblos Ship", which originally defined a class of Egyptian seagoing ships used on the Byblos run; however, by the end of the Old Kingdom, the term had come to include large seagoing ships, whatever their destination. In 1977, an ancient north–south canal was discovered extending from Lake Timsah to the Ballah Lakes. It was dated to the Middle Kingdom of Egypt by extrapolating dates of ancient sites constructed along its course. In 2011, archaeologists from Italy, the United States, and Egypt excavating a dried-up lagoon known as Mersa Gawasis have unearthed traces of an ancient harbor that once launched early voyages like Hatshepsut's Punt expedition onto the open ocean. Some of the site's most evocative evidence for the ancient Egyptians' seafaring prowess include large ship timbers and hundreds of feet of ropes, made from papyrus, coiled in huge bundles. In 2013, a team of Franco-Egyptian archaeologists discovered what is believed to be the world's oldest port, dating back about 4500 years, from the time of King Cheops on the Red Sea coast near Wadi el-Jarf (about 110 miles south of Suez). Mathematics The earliest attested examples of mathematical calculations date to the predynastic Naqada period, and show a fully developed numeral system. The importance of mathematics to an educated Egyptian is suggested by a New Kingdom fictional letter in which the writer proposes a scholarly competition between himself and another scribe regarding everyday calculation tasks such as accounting of land, labor, and grain. Texts such as the Rhind Mathematical Papyrus and the Moscow Mathematical Papyrus show that the ancient Egyptians could perform the four basic mathematical operations—addition, subtraction, multiplication, and division—use fractions, calculate the areas of rectangles, triangles, and circles and compute the volumes of boxes, columns and pyramids. They understood basic concepts of algebra and geometry, and could solve simple sets of simultaneous equations. Mathematical notation was decimal, and based on hieroglyphic signs for each power of ten up to one million. Each of these could be written as many times as necessary to add up to the desired number; so to write the number eighty or eight hundred, the symbol for ten or one hundred was written eight times respectively. Because their methods of calculation could not handle most fractions with a numerator greater than one, they had to write fractions as the sum of several fractions. For example, they resolved the fraction two-fifths into the sum of one-third + one-fifteenth. Standard tables of values facilitated this. Some common fractions, however, were written with a special glyph—the equivalent of the modern two-thirds is shown on the right. Ancient Egyptian mathematicians knew the Pythagorean theorem as an empirical formula. They were aware, for example, that a triangle had a right angle opposite the hypotenuse when its sides were in a 3–4–5 ratio. They were able to estimate the area of a circle by subtracting one-ninth from its diameter and squaring the result: Area ≈ [()D]2 = ()r2 ≈ 3.16r2, a reasonable approximation of the formula . The golden ratio seems to be reflected in many Egyptian constructions, including the pyramids, but its use may have been an unintended consequence of the ancient Egyptian practice of combining the use of knotted ropes with an intuitive sense of proportion and harmony. Population Estimates of the size of the population range from 1-1.5 million in the 3rd millennium BCE to possibly 2-3 million by the 1st millennium BCE, before growing significantly towards the end of that millennium. DNA In 2012, the DNA of the 20th dynasty mummies of Ramesses III and another mummy believed to be Ramesses III's son Pentawer were analyzed by Albert Zink, Yehia Z Gad and a team of researchers under Zahi Hawass, then Secretary General of the Supreme Council of Antiquities, Egypt. Genetic kinship analyses revealed identical haplotypes in both mummies. Using the Whit Athey's haplogroup predictor, they identified the Y chromosomal haplogroup E1b1a (E-M2). In 2017, a team led by led by researchers from the University of Tuebingen and the Max Planck Institute for the Science of Human History in Jena tested the maternal DNA (mitochondrial) of 90 mummies from Abusir el-Meleq in northern Egypt (near Cairo), which was the first reliable data using high-throughput DNA sequencing methods. Additionally, three of the mummies were also analyzed for Y-DNA. Two were assigned to West Asian J and one to haplogroup E1b1b1 both common in North Africa. The researchers cautioned that the affinities of the examined ancient Egyptian specimens may not be representative of those of all ancient Egyptians since they were from a single archaeological site. Whilst not conclusive since the few relatively older mummies only go back to the 18th-19th dynasty, the rest being from then up to late Roman period, the authors of this study said the Abusir el-Meleq mummies "closely resembled ancient and modern Near Eastern populations, especially those in the Levant." The genetics of the mummies remained remarkably consistent within this range even as different powers—including Nubians, Greeks, and Romans—conquered the empire." A wide range of mtDNA haplogroups were found including clades of J, U, H, HV, M, R0, R2, K, T, L, I, N, X, W. The authors of the study noted that the mummies at Abusir el-Meleq have 6–15% maternal sub-Saharan DNA while modern Egyptians have a little more sub-Saharan ancestry, 15% to 20%, suggesting some degree of influx after the end of the empire. Other genetic studies show greater levels of sub-Saharan African ancestry in modern southern Egyptian populations and anticipate that mummies from southern Egypt would show greater levels of sub-Saharan African ancestry. In 2018, the 4000-year-old mummified head of Djehutynakht, a governor in the Middle Kingdom of the 11th or 12th dynasty, was analyzed for mitochondrial DNA. The sequence of the mummy most closely resembles a U5a lineage from sample JK2903, a much more recent 2000-year-old skeleton from the Abusir el-Meleq site in Egypt, although no direct matches to the Djehutynakht sequence have been reported. Haplogroup U5 is also found in modern-day Berbers from the Siwa Oasis in Egypt. A 2008 article by C. Coudray, "The complex and diversified mitochondrial gene pool of Berber populations", recorded haplogroup U5 at 16.7% for the Siwa whereas haplogroup U6 is more common in other Berber populations to the west of Egypt. In 2020, Yehia Z Gad and other researchers of the Hawass team published results of an analysis of the maternal and paternal haplogroups of several 18th dynasty mummies, including Tutankhamun. Genetic analysis indicated the following haplogroups: Tutankhamun YDNA R1b / mtDNA K Akhenaten YDNA R1b / mtDNA K Amenhotep III YDNA R1b / mtDNA K Yuya G2a / mtDNA K Tiye mtDNA K Thuya mtDNA K The clade of R1b was not determined. A high frequency of R1b1a2 (R-V88) (26.9%) was observed among the Berbers from the Siwa Oasis. This haplogroup reaches its highest frequency in northern Cameroon, northern Nigeria, Chad, and Niger. Legacy The culture and monuments of ancient Egypt have left a lasting legacy on the world. Egyptian civilization significantly influenced the Kingdom of Kush and Meroë with both adopting Egyptian religious and architectural norms (hundreds of pyramids (6–30 meters high) were built in Egypt/Sudan), as well as using Egyptian writing as the basis of the Meroitic script. Meroitic is the oldest written language in Africa, other than Egyptian, and was used from the 2nd century BC until the early 5th century AD. The cult of the goddess Isis, for example, became popular in the Roman Empire, as obelisks and other relics were transported back to Rome. The Romans also imported building materials from Egypt to erect Egyptian-style structures. Early historians such as Herodotus, Strabo, and Diodorus Siculus studied and wrote about the land, which Romans came to view as a place of mystery. During the Middle Ages and the Renaissance, Egyptian pagan culture was in decline after the rise of Christianity and later Islam, but interest in Egyptian antiquity continued in the writings of medieval scholars such as Dhul-Nun al-Misri and al-Maqrizi. In the seventeenth and eighteenth centuries, European travelers and tourists brought back antiquities and wrote stories of their journeys, leading to a wave of Egyptomania across Europe. This renewed interest sent collectors to Egypt, who took, purchased, or were given many important antiquities. Napoleon arranged the first studies in Egyptology when he brought some 150 scientists and artists to study and document Egypt's natural history, which was published in the Description de l'Égypte. In the 20th century, the Egyptian Government and archaeologists alike recognized the importance of cultural respect and integrity in excavations. The Ministry of Tourism and Antiquities (formerly Supreme Council of Antiquities) now approves and oversees all excavations, which are aimed at finding information rather than treasure. The council also supervises museums and monument reconstruction programs designed to preserve the historical legacy of Egypt.

Alan Alexander Milne (; 18 January 1882 – 31 January 1956) was an English author, best known for his books about the teddy bear Winnie-the-Pooh and for various poems. Milne was a noted writer, primarily as a playwright, before the huge success of Pooh overshadowed all his previous work. Milne served in both World Wars, joining the British Army in World War I, and as a captain of the British Home Guard in World War II. He was the father of bookseller Christopher Robin Milne, upon whom the character Christopher Robin is based. Early life and military career Alan Alexander Milne was born in Kilburn, London, to John Vine Milne, who was born in England, and Sarah Marie Milne (née Heginbotham). He grew up at Henley House School, 6/7 Mortimer Road (now Crescent), Kilburn, a small independent school run by his father. One of his teachers was H. G. Wells, who taught there in 1889–90. Milne attended Westminster School and Trinity College, Cambridge, where he studied on a mathematics scholarship, graduating with a B.A. in Mathematics in 1903. He edited and wrote for Granta, a student magazine. He collaborated with his brother Kenneth and their articles appeared over the initials AKM. Milne's work came to the attention of the leading British humour magazine Punch, where Milne was to become a contributor and later an assistant editor. Considered a talented cricket fielder, Milne played for two amateur teams that were largely composed of British writers: the Allahakbarries and the Authors XI. His teammates included fellow writers J. M. Barrie, Arthur Conan Doyle and P. G. Wodehouse. Milne joined the British Army in World War I and served as an officer in the Royal Warwickshire Regiment and later, after a debilitating illness, the Royal Corps of Signals. He was commissioned into the 4th Battalion, Royal Warwickshire Regiment, on 1 February 1915 as a second lieutenant (on probation). His commission was confirmed on 20 December 1915. On 7 July 1916, he was injured in the Battle of the Somme and invalided back to England. Having recuperated, he was recruited into Military Intelligence to write propaganda articles for MI7 (b) between 1916 and 1918. He was discharged on 14 February 1919, and settled in Mallord Street, Chelsea. He relinquished his commission on 19 February 1920, retaining the rank of lieutenant. After the war, he wrote a denunciation of war titled Peace with Honour (1934), which he retracted somewhat with 1940's War with Honour. During World War II, Milne was one of the most prominent critics of fellow English writer (and Authors XI cricket teammate) P. G. Wodehouse, who was captured at his country home in France by the Nazis and imprisoned for a year. Wodehouse made radio broadcasts about his internment, which were broadcast from Berlin. Although the light-hearted broadcasts made fun of the Germans, Milne accused Wodehouse of committing an act of near treason by cooperating with his country's enemy. Wodehouse got some revenge on his former friend (e.g. in The Mating Season) by creating fatuous parodies of the Christopher Robin poems in some of his later stories, and claiming that Milne "was probably jealous of all other writers.... But I loved his stuff." Milne married Dorothy "Daphne" de Sélincourt (1890–1971) in 1913 and their son Christopher Robin Milne was born in 1920. In 1925, Milne bought a country home, Cotchford Farm, in Hartfield, East Sussex. During World War II, Milne was a captain in the British Home Guard in Hartfield & Forest Row, insisting on being plain "Mr. Milne" to the members of his platoon. He retired to the farm after a stroke and brain surgery in 1952 left him an invalid, and by August 1953, "he seemed very old and disenchanted." Milne died in January 1956, aged 74. Literary career 1903 to 1925 After graduating from Cambridge University in 1903, A. A. Milne contributed humorous verse and whimsical essays to Punch, joining the staff in 1906 and becoming an assistant editor. During this period he published 18 plays and three novels, including the murder mystery The Red House Mystery (1922). His son was born in August 1920 and in 1924 Milne produced a collection of children's poems, When We Were Very Young, which were illustrated by Punch staff cartoonist E. H. Shepard. A collection of short stories for children A Gallery of Children, and other stories that became part of the Winnie-the-Pooh books, were first published in 1925. Milne was an early screenwriter for the nascent British film industry, writing four stories filmed in 1920 for the company Minerva Films (founded in 1920 by the actor Leslie Howard and his friend and story editor Adrian Brunel). These were The Bump, starring Aubrey Smith; Twice Two; Five Pound Reward; and Bookworms. Some of these films survive in the archives of the British Film Institute. Milne had met Howard when the actor starred in Milne's play Mr Pim Passes By in London. Looking back on this period (in 1926), Milne observed that when he told his agent that he was going to write a detective story, he was told that what the country wanted from a "Punch humorist" was a humorous story; when two years later he said he was writing nursery rhymes, his agent and publisher were convinced he should write another detective story; and after another two years, he was being told that writing a detective story would be in the worst of taste given the demand for children's books. He concluded that "the only excuse which I have yet discovered for writing anything is that I want to write it; and I should be as proud to be delivered of a Telephone Directory con amore as I should be ashamed to create a Blank Verse Tragedy at the bidding of others." 1926 to 1928 Milne is most famous for his two Pooh books about a boy named Christopher Robin after his son, Christopher Robin Milne (1920–1996), and various characters inspired by his son's stuffed animals, most notably the bear named Winnie-the-Pooh. Christopher Robin Milne's stuffed bear, originally named Edward, was renamed Winnie after a Canadian black bear named Winnie (after Winnipeg), which was used as a military mascot in World War I, and left to London Zoo during the war. "The Pooh" comes from a swan the young Milne named "Pooh". E. H. Shepard illustrated the original Pooh books, using his own son's teddy Growler ("a magnificent bear") as the model. The rest of Christopher Robin Milne's toys, Piglet, Eeyore, Kanga, Roo and Tigger, were incorporated into A. A. Milne's stories, and two more characters – Rabbit and Owl – were created by Milne's imagination. Christopher Robin Milne's own toys are now on display in New York where 750,000 people visit them every year. The fictional Hundred Acre Wood of the Pooh stories derives from Five Hundred Acre Wood in Ashdown Forest in East Sussex, South East England, where the Pooh stories were set. Milne lived on the northern edge of the forest at Cotchford Farm, , and took his son walking there. E. H. Shepard drew on the landscapes of Ashdown Forest as inspiration for many of the illustrations he provided for the Pooh books. The adult Christopher Robin commented: "Pooh's Forest and Ashdown Forest are identical." Popular tourist locations at Ashdown Forest include: Galleon's Lap, The Enchanted Place, the Heffalump Trap and Lone Pine, Eeyore’s Sad and Gloomy Place, and the wooden Pooh Bridge where Pooh and Piglet invented Poohsticks. Not yet known as Pooh, he made his first appearance in a poem, "Teddy Bear", published in Punch magazine in February 1924 and republished in When We Were Very Young. Pooh first appeared in the London Evening News on Christmas Eve, 1925, in a story called "The Wrong Sort of Bees". Winnie-the-Pooh was published in 1926, followed by The House at Pooh Corner in 1928. A second collection of nursery rhymes, Now We Are Six, was published in 1927. All four books were illustrated by E. H. Shepard. Milne also published four plays in this period. He also "gallantly stepped forward" to contribute a quarter of the costs of dramatising P. G. Wodehouse's A Damsel in Distress. The World of Pooh won the Lewis Carroll Shelf Award in 1958. 1929 onwards The success of his children's books was to become a source of considerable annoyance to Milne, whose self-avowed aim was to write whatever he pleased and who had, until then, found a ready audience for each change of direction: he had freed pre-war Punch from its ponderous facetiousness; he had made a considerable reputation as a playwright (like his idol J. M. Barrie) on both sides of the Atlantic; he had produced a witty piece of detective writing in The Red House Mystery (although this was severely criticised by Raymond Chandler for the implausibility of its plot in his essay The Simple Art of Murder in the eponymous collection that appeared in 1950). But once Milne had, in his own words, "said goodbye to all that in 70,000 words" (the approximate length of his four principal children's books), he had no intention of producing any reworkings lacking in originality, given that one of the sources of inspiration, his son, was growing older. Another reason Milne stopped writing children's books, and especially about Winnie-the-Pooh, was that he felt "amazement and disgust" over the fame his son was exposed to, and said that "I feel that the legal Christopher Robin has already had more publicity than I want for him. I do not want CR Milne to ever wish that his name were Charles Robert." In his literary home, Punch, where the When We Were Very Young verses had first appeared, Methuen continued to publish whatever Milne wrote, including the long poem "The Norman Church" and an assembly of articles entitled Year In, Year Out (which Milne likened to a benefit night for the author). In 1930, Milne adapted Kenneth Grahame's novel The Wind in the Willows for the stage as Toad of Toad Hall. The title was an implicit admission that such chapters as Chapter 7, "The Piper at the Gates of Dawn," could not survive translation to the theatre. A special introduction written by Milne is included in some editions of Grahame's novel. Milne and his wife became estranged from their son, who came to resent what he saw as his father's exploitation of his childhood and came to hate the books that had thrust him into the public eye. Christopher's marriage to his first cousin, Lesley de Sélincourt, distanced him still further from his parents – Lesley's father and Christopher's mother had not spoken to each other for 30 years. Death and legacy Commemoration A. A. Milne died at his home in Hartfield, Sussex, on 31 January 1956, nearly two weeks after his 74th birthday. After a memorial service in London, his ashes were scattered in a crematorium's memorial garden in Brighton. The rights to A. A. Milne's Pooh books were left to four beneficiaries: his family, the Royal Literary Fund, Westminster School and the Garrick Club. After Milne's death in 1956, thirteen days after his 74th birthday, his widow sold her rights to the Pooh characters to Stephen Slesinger, whose widow sold the rights after Slesinger's death to the Walt Disney Company, which has made many Pooh cartoon movies, a Disney Channel television show, as well as Pooh-related merchandise. In 2001, the other beneficiaries sold their interest in the estate to the Disney Corporation for $350m. Previously Disney had been paying twice-yearly royalties to these beneficiaries. The estate of E. H. Shepard also received a sum in the deal. The UK copyright on the text of the original Winnie the Pooh books expires on 1 January 2027; at the beginning of the year after the 70th anniversary of the author's death (PMA-70), and has already expired in those countries with a PMA-50 rule. This applies to all of Milne's works except those first published posthumously. The illustrations in the Pooh books will remain under copyright until the same amount of time has passed, after the illustrator's death; in the UK, this will be on 1 January 2047. In the United States, copyright will not expire until 95 years after publication for each of Milne's books first published before 1978, but this includes the illustrations. In 2008, a collection of original illustrations featuring Winnie-the-Pooh and his animal friends sold for more than £1.2 million at auction in Sotheby's, London. Forbes magazine ranked Winnie the Pooh the most valuable fictional character in 2002; Winnie the Pooh merchandising products alone had annual sales of more than $5.9 billion. In 2005, Winnie the Pooh generated $6 billion, a figure surpassed only by Mickey Mouse. A memorial plaque in Ashdown Forest, unveiled by Christopher Robin in 1979, commemorates the work of A. A. Milne and Shepard in creating the world of Pooh. Milne once wrote of Ashdown Forest: "In that enchanted place on the top of the forest a little boy and his bear will always be playing." In 2003, Winnie the Pooh was listed at number 7 on the BBC's poll The Big Read which determined the UK's "best-loved novels" of all time. In 2006, Winnie the Pooh received a star on the Hollywood Walk of Fame, marking the 80th birthday of Milne's creation. That same year a UK poll saw Winnie the Pooh voted onto the list of icons of England. Marking the 90th anniversary of Milne's creation of the character, and the 90th birthday of Elizabeth II, in 2016 a new story sees Winnie the Pooh meet the Queen at Buckingham Palace. The illustrated and audio adventure is titled Winnie-the-Pooh Meets the Queen, and has been narrated by actor Jim Broadbent. Also in 2016, a new character, a Penguin, was unveiled in The Best Bear in All the World, which was inspired by a long-lost photograph of Milne and his son Christopher with a toy penguin. Several of Milne's children's poems were set to music by the composer Harold Fraser-Simson. His poems have been parodied many times, including with the books When We Were Rather Older and Now We Are Sixty. The 1963 film The King's Breakfast was based on Milne's poem of the same name. The Pooh books were used as the basis for two academic satires by Frederick C Crews: 'The Pooh Perplex'(1963–4) and 'Postmodern Pooh'(2002). An exhibition entitled "Winnie-the-Pooh: Exploring a Classic" appeared at the V & A from 9 December 2017 to 8 April 2018. An elementary school in Houston, Texas, United States, operated by the Houston Independent School District (HISD), is named after Milne. The school, A. A. Milne Elementary School in Brays Oaks, opened in 1991. Archive The bulk of A. A. Milne's papers are housed at the Harry Ransom Center at the University of Texas at Austin. The collection, established at the center in 1964, consists of manuscript drafts and fragments for over 150 of Milne's works, as well as correspondence, legal documents, genealogical records, and some personal effects. The library division holds several books formerly belonging to Milne and his wife Dorothy. The Harry Ransom Center also has small collections of correspondence from Christopher Robin Milne and Milne's frequent illustrator Ernest Shepard. The original manuscripts for Winnie the Pooh and The House at Pooh Corner are archived separately at Trinity College Library, Cambridge. Religious views Milne did not speak out much on the subject of religion, although he used religious terms to explain his decision, while remaining a pacifist, to join the British Home Guard: "In fighting Hitler," he wrote, "we are truly fighting the Devil, the Anti-Christ ...

August is the eighth month of the year in the Julian and Gregorian calendars, and the fifth of seven months to have a length of 31 days. Its zodiac sign is Leo and was originally named Sextilis in Latin because it was the 6th month in the original ten-month Roman calendar under Romulus in 753 BC, with March being the first month of the year. About 700 BC, it became the eighth month when January and February were added to the year before March by King Numa Pompilius, who also gave it 29 days. Julius Caesar added two days when he created the Julian calendar in 46 BC (708 AUC), giving it its modern length of 31 days. In 8 BC, it was renamed in honor of Emperor Augustus. According to a Senatus consultum quoted by Macrobius, he chose this month because it was the time of several of his great triumphs, including the conquest of Egypt. Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, but this is an invention of the 13th century scholar Johannes de Sacrobosco. Sextilis in fact had 31 days before it was renamed, and it was not chosen for its length. In the Southern Hemisphere, August is the seasonal equivalent of February in the Northern Hemisphere. In the Northern Hemisphere, August falls in the season of summer. In the Southern Hemisphere, the month falls during the season of winter. In many European countries, August is the holiday month for most workers. Numerous religious holidays occurred during August in ancient Rome. Certain meteor showers take place in August. The Kappa Cygnids take place in August, with the dates varying each year. The Alpha Capricornids meteor shower takes place as early as July 10 and ends at around August 10, and the Southern Delta Aquariids take place from mid-July to mid-August, with the peak usually around July 28–29. The Perseids, a major meteor shower, typically takes place between July 17 and August 24, with the days of the peak varying yearly. The star cluster of Messier 30 is best observed around August. Among the aborigines of the Canary Islands, especially among the Guanches of Tenerife, the month of August received in the name of Beñesmer or Beñesmen, which was also the harvest festival held this month. August symbols August's birthstones are the peridot, sardonyx, and spinel. Its birth flower is the gladiolus or poppy, meaning beauty, strength of character, love, marriage and family. The Western zodiac signs for the month of August are Leo (until August 22) and Virgo (from August 23 onwards).

André Paul Guillaume Gide (; 22 November 1869 – 19 February 1951) was a French author and winner of the Nobel Prize in Literature (in 1947). Gide's career ranged from its beginnings in the symbolist movement, to the advent of anticolonialism between the two World Wars. The author of more than fifty books, at the time of his death his obituary in The New York Times described him as "France's greatest contemporary man of letters" and "judged the greatest French writer of this century by the literary cognoscenti." Known for his fiction as well as his autobiographical works, Gide exposed to public view the conflict and eventual reconciliation of the two sides of his personality (characterized by a Protestant austerity and a transgressive sexual adventurousness, respectively), which a strict and moralistic education had helped set at odds. Gide's work can be seen as an investigation of freedom and empowerment in the face of moralistic and puritanical constraints, and centers on his continuous effort to achieve intellectual honesty. His self-exploratory texts reflect his search of how to be fully oneself, including owning one's sexual nature, without at the same time betraying one's values. His political activity was shaped by the same ethos, as indicated by his repudiation of communism after his 1936 journey to the USSR. Early life Gide was born in Paris on 22 November 1869, into a middle-class Protestant family. His father was a Paris University professor of law who died in 1880, Jean Paul Guillaume Gide, and his mother was Juliette Maria Rondeaux. His uncle was the political economist Charles Gide. His paternal family traced its roots back to Italy, with his ancestors, the Guidos, moving to France and other western and northern European countries after converting to Protestantism during the 16th century, due to persecution. Gide was brought up in isolated conditions in Normandy and became a prolific writer at an early age, publishing his first novel, The Notebooks of André Walter (French: Les Cahiers d'André Walter), in 1891, at the age of twenty-one. In 1893 and 1894, Gide traveled in Northern Africa, and it was there that he came to accept his attraction to boys. He befriended Oscar Wilde in Paris, and in 1895 Gide and Wilde met in Algiers. Wilde had the impression that he had introduced Gide to homosexuality, but, in fact, Gide had already discovered this on his own. The middle years In 1895, after his mother's death, he married his cousin Madeleine Rondeaux, but the marriage remained unconsummated. In 1896, he became mayor of La Roque-Baignard, a commune in Normandy. In 1901, Gide rented the property Maderia in St. Brélade's Bay and lived there while residing in Jersey. This period, 1901–07, is commonly seen as a time of apathy and turmoil for him. In 1908, Gide helped found the literary magazine Nouvelle Revue Française (The New French Review). During The Great War Gide visited England. One of his friends there was the artist William Rothenstein. Rothenstein described Gide's visit to his Gloucestershire home in his autobiography: André Gide was in England during the war. ... He came to stay with us for a time, and brought with him a young nephew, whose English was better than his own. The boy made friends with my son John, while Gide and I discussed everything under the sun. Once again I delighted in the range and subtlety of a Frenchman’s intelligence; and I regretted my long severance from France. Nobody understood art more profoundly than Gide, no one’s view of life was more penetrating. ... Gide had a half satanic, half monk-like mien; he put one in mind of portraits of Baudelaire. Withal there was something exotic about him. He would appear in a red waistcoat, black velvet jacket and beige-coloured trousers and, in lieu of collar and tie, a loosely knotted scarf. ... The heart of man held no secrets for Gide. There was little that he didn’t understand, or discuss. He suffered, as I did, from the banishment of truth, one of the distressing symptoms of war. The Germans were not all black, and the Allies all white, for Gide. In 1916, Marc Allégret, only 15 years old, became his lover. Marc was the son – one of five children – of Élie Allégret, who years before had been hired by Gide's mother to tutor her son in light of his weak grades in school, after which he and Gide became fast friends; Élie Allégret was best man at Gide's wedding. Gide and Marc fled to London, in retribution for which his wife burned all his correspondence – "the best part of myself," he later commented. In 1918, he met Dorothy Bussy, who was his friend for over thirty years and translated many of his works into English. Gide was close friends with the critic Charles Du Bos. Together they were part of the Foyer Franco-Belge, in which capacity they worked to find employment, food and housing for Franco-Belgian refugees who arrived in Paris following the German invasion of Belgium. Their friendship later declined, due to Du Bos' perception of Gide as disavowing or betraying his spiritual faith, in contrast to Du Bos' own return to faith. Du Bos' essay Dialogue avec André Gide was published in 1929. The essay, informed by Du Bos' Catholic convictions, condemned Gide's homosexuality. Gide and Du Bos' mutual friend Ernst Robert Curtius criticised the book in a letter to Gide, writing that "he [Du Bos] judges you according to Catholic morals suffices to neglect his complete indictment. It can only touch those who think like him and are convinced in advance. He has abdicated his intellectual liberty." In the 1920s, Gide became an inspiration for writers such as Albert Camus and Jean-Paul Sartre. In 1923, he published a book on Fyodor Dostoyevsky; however, when he defended homosexuality in the public edition of Corydon (1924) he received widespread condemnation. He later considered this his most important work. In 1923, he sired a daughter, Catherine, by Elisabeth van Rysselberghe, a woman who was much younger than he. He had known her for a long time, as she was the daughter of his closest female friend, Maria Monnom, the wife of his friend the Belgian neo-impressionist painter Théo van Rysselberghe. This caused the only crisis in the long-standing relationship between Allégret and Gide and damaged the relation with van Rysselberghe. This was possibly Gide's only sexual relationship with a woman, and it was brief in the extreme. Catherine became his only descendant by blood. He liked to call Elisabeth "La Dame Blanche" ("The White Lady"). Elisabeth eventually left her husband to move to Paris and manage the practical aspects of Gide's life (they had adjoining apartments built for each on the rue Vavin). She worshiped him, but evidently they no longer had a sexual relationship. Gide's legal wife, Madeleine, died in 1938. Later he explored their unconsummated marriage in his memoir of Madeleine, Et nunc manet in te. In 1924, he published an autobiography, If it Die... (French: Si le grain ne meurt). In the same year, he produced the first French language editions of Joseph Conrad's Heart of Darkness and Lord Jim. After 1925, he began to campaign for more humane conditions for convicted criminals. Africa From July 1926 to May 1927, he traveled through the French Equatorial Africa colony with his lover Marc Allégret. Gide went successively to Middle Congo (now the Republic of the Congo), Ubangi-Shari (now the Central African Republic), briefly to Chad and then to Cameroon before returning to France. He related his peregrinations in a journal called Travels in the Congo (French: Voyage au Congo) and Return from Chad (French: Retour du Tchad). In this published journal, he criticized the behavior of French business interests in the Congo and inspired reform. In particular, he strongly criticized the Large Concessions regime (French: Régime des Grandes Concessions), i.e., a regime that conceded part of the colony to French companies and where these companies could exploit all of the area's natural resources, in particular rubber. He related, for instance, how natives were forced to leave their village for several weeks to collect rubber in the forest, and went as far as comparing their exploitation to slavery. The book had important influence on anti-colonialism movements in France and helped re-evaluate the impact of colonialism. Soviet Union During the 1930s, he briefly became a communist, or more precisely, a fellow traveler (he never formally joined any communist party). As a distinguished writer sympathizing with the cause of communism, he was invited to speak at Maxim Gorky's funeral and to tour the Soviet Union as a guest of the Soviet Union of Writers. He encountered censorship of his speeches and was particularly disillusioned with the state of culture under Soviet communism, breaking with his socialist friends in Retour de L'U.R.S.S. in 1936. In the 1949 anthology The God That Failed Gide describes his early enthusiasm: 1930s and 1940s In 1930 Gide published a book about the Blanche Monnier case called La Séquestrée de Poitiers, changing little but the names of the protagonists. Monnier was a young woman who was kept captive by her own mother for more than 25 years. In 1939, Gide became the first living author to be published in the prestigious Bibliothèque de la Pléiade. He left France for Africa in 1942 and lived in Tunis from December 1942 until it was re-taken by French, British and American forces in May 1943 and he was able to travel to Algiers where he stayed until the end of World War II. In 1947, he received the Nobel Prize in Literature "for his comprehensive and artistically significant writings, in which human problems and conditions have been presented with a fearless love of truth and keen psychological insight". He devoted much of his last years to publishing his Journal. Gide died in Paris on 19 February 1951. The Roman Catholic Church placed his works on the Index of Forbidden Books in 1952. Gide's life as a writer Gide's biographer Alan Sheridan summed up Gide's life as a writer and an intellectual: "Gide's fame rested ultimately, of course, on his literary works. But, unlike many writers, he was no recluse: he had a need of friendship and a genius for sustaining it." But his "capacity for love was not confined to his friends: it spilled over into a concern for others less fortunate than himself." Writings André Gide's writings spanned many genres – "As a master of prose narrative, occasional dramatist and translator, literary critic, letter writer, essayist, and diarist, André Gide provided twentieth-century French literature with one of its most intriguing examples of the man of letters." But as Gide's biographer Alan Sheridan points out, "It is the fiction that lies at the summit of Gide's work." "Here, as in the oeuvre as a whole, what strikes one first is the variety. Here, too, we see Gide's curiosity, his youthfulness, at work: a refusal to mine only one seam, to repeat successful formulas...The fiction spans the early years of Symbolism, to the "comic, more inventive, even fantastic" pieces, to the later "serious, heavily autobiographical, first-person narratives"...In France Gide was considered a great stylist in the classical sense, "with his clear, succinct, spare, deliberately, subtly phrased sentences." Gide's surviving letters run into the thousands. But it is the Journal that Sheridan calls "the pre-eminently Gidean mode of expression." "His first novel emerged from Gide's own journal, and many of the first-person narratives read more or less like journals. In Les faux-monnayeurs, Edouard's journal provides an alternative voice to the narrator's." "In 1946, when Pierre Herbert asked Gide which of his books he would choose if only one were to survive," Gide replied, 'I think it would be my Journal.'''" Beginning at the age of eighteen or nineteen, Gide kept a journal all of his life and when these were first made available to the public, they ran to thirteen hundred pages. Struggle for values "Each volume that Gide wrote was intended to challenge itself, what had preceded it, and what could conceivably follow it. This characteristic, according to Daniel Moutote in his Cahiers de André Gide essay, is what makes Gide's work 'essentially modern': the 'perpetual renewal of the values by which one lives.'" Gide wrote in his Journal in 1930: "The only drama that really interests me and that I should always be willing to depict anew, is the debate of the individual with whatever keeps him from being authentic, with whatever is opposed to his integrity, to his integration. Most often the obstacle is within him. And all the rest is merely accidental." As a whole, "The works of André Gide reveal his passionate revolt against the restraints and conventions inherited from 19th-century France. He sought to uncover the authentic self beneath its contradictory masks." Sexuality In his journal, Gide distinguishes between adult-attracted "sodomites" and boy-loving "pederasts", categorizing himself as the latter.

Abbot (from the Aramaic Abba meaning "father") is an ecclesiastical title given to the male head of a monastery in various Western religious traditions, including Christianity. The office may also be given as an honorary title to a clergyman who is not the head of a monastery. The female equivalent is abbess. Origins The title had its origin in the monasteries of Egypt and Syria, spread through the eastern Mediterranean, and soon became accepted generally in all languages as the designation of the head of a monastery. The word is derived from the Aramaic meaning "father" or , meaning "my father" (it still has this meaning in contemporary Israeli Hebrew: אבא) In the Septuagint, it was written as "abbas". At first it was employed as a respectful title for any monk, but it was soon restricted by canon law to certain priestly superiors. At times it was applied to various priests, e.g. at the court of the Frankish monarchy the ("of the palace"') and ("of the camp") were chaplains to the Merovingian and Carolingian sovereigns’ court and army respectively. The title of abbot came into fairly general use in western monastic orders whose members include priests. Monastic history An abbot (from , , from ("father"), from (), from / (, "father"); compare ; ) is the head and chief governor of a community of monks, called also in the East hegumen or archimandrite. The English version for a female monastic head is abbess. Early history In Egypt, the first home of monasticism, the jurisdiction of the abbot, or archimandrite, was but loosely defined. Sometimes he ruled over only one community, sometimes over several, each of which had its own abbot as well. Saint John Cassian speaks of an abbot of the Thebaid who had 500 monks under him. By the Rule of St Benedict, which, until the Cluniac reforms, was the norm in the West, the abbot has jurisdiction over only one community. The rule, as was inevitable, was subject to frequent violations; but it was not until the foundation of the Cluniac Order that the idea of a supreme abbot, exercising jurisdiction over all the houses of an order, was definitely recognised. Monks, as a rule, were laymen, nor at the outset was the abbot any exception. For the reception of the sacraments, and for other religious offices, the abbot and his monks were commanded to attend the nearest church. This rule proved inconvenient when a monastery was situated in a desert or at a distance from a city, and necessity compelled the ordination of some monks. This innovation was not introduced without a struggle, ecclesiastical dignity being regarded as inconsistent with the higher spiritual life, but, before the close of the 5th century, at least in the East, abbots seem almost universally to have become deacons, if not priests. The change spread more slowly in the West, where the office of abbot was commonly filled by laymen till the end of the 7th century. The ecclesiastical leadership exercised by abbots despite their frequent lay status is proved by their attendance and votes at ecclesiastical councils. Thus at the first Council of Constantinople, AD 448, 23 archimandrites or abbots sign, with 30 bishops. The second Council of Nicaea, AD 787, recognized the right of abbots to ordain their monks to the inferior orders below the diaconate, a power usually reserved to bishops. Abbots used to be subject to episcopal jurisdiction, and continued generally so, in fact, in the West till the 11th century. The Code of Justinian (lib. i. tit. iii. de Ep. leg. xl.) expressly subordinates the abbot to episcopal oversight. The first case recorded of the partial exemption of an abbot from episcopal control is that of Faustus, abbot of Lerins, at the council of Arles, AD 456; but the exorbitant claims and exactions of bishops, to which this repugnance to episcopal control is to be traced, far more than to the arrogance of abbots, rendered it increasingly frequent, and, in the 6th century, the practice of exempting religious houses partly or altogether from episcopal control, and making them responsible to the pope alone, received an impulse from Pope Gregory the Great. These exceptions, introduced with a good object, had grown into a widespread evil by the 12th century, virtually creating an imperium in imperio, and depriving the bishop of all authority over the chief centres of influence in his diocese. Later Middle Ages In the 12th century, the abbots of Fulda claimed precedence of the archbishop of Cologne. Abbots more and more assumed almost episcopal state, and in defiance of the prohibition of early councils and the protests of St Bernard and others, adopted the episcopal insignia of mitre, ring, gloves and sandals. It has been maintained that the right to wear mitres was sometimes granted by the popes to abbots before the 11th century, but the documents on which this claim is based are not genuine (J. Braun, Liturgische Gewandung, p. 453). The first undoubted instance is the bull by which Alexander II in 1063 granted the use of the mitre to Egelsinus, abbot of the monastery of St Augustine at Canterbury. The mitred abbots in England were those of Abingdon, St Alban's, Bardney, Battle, Bury St Edmunds, St Augustine's Canterbury, Colchester, Croyland, Evesham, Glastonbury, Gloucester, St Benet's Hulme, Hyde, Malmesbury, Peterborough, Ramsey, Reading, Selby, Shrewsbury, Tavistock, Thorney, Westminster, Winchcombe, and St Mary's York. Of these the precedence was yielded to the abbot of Glastonbury, until in AD 1154 Adrian IV (Nicholas Breakspear) granted it to the abbot of St Alban's, in which monastery he had been brought up. Next after the abbot of St Alban's ranked the abbot of Westminster and then Ramsey. Elsewhere, the mitred abbots that sat in the Estates of Scotland were of Arbroath, Cambuskenneth, Coupar Angus, Dunfermline, Holyrood, Iona, Kelso, Kilwinning, Kinloss, Lindores, Paisley, Melrose, Scone, St Andrews Priory and Sweetheart. To distinguish abbots from bishops, it was ordained that their mitre should be made of less costly materials, and should not be ornamented with gold, a rule which was soon entirely disregarded, and that the crook of their pastoral staff (the crosier) should turn inwards instead of outwards, indicating that their jurisdiction was limited to their own house. The adoption of certain episcopal insignia (pontificalia) by abbots was followed by an encroachment on episcopal functions, which had to be specially but ineffectually guarded against by the Lateran council, AD 1123. In the East abbots, if in priests' orders and with the consent of the bishop, were, as we have seen, permitted by the second Nicene council, AD 787, to confer the tonsure and admit to the order of reader; but gradually abbots, in the West also, advanced higher claims, until we find them in AD 1489 permitted by Innocent IV to confer both the subdiaconate and diaconate. Of course, they always and everywhere had the power of admitting their own monks and vesting them with the religious habit. The power of the abbot was paternal but absolute, limited, however, by the canon law. One of the main goals of monasticism was the purgation of self and selfishness, and obedience was seen as a path to that perfection. It was sacred duty to execute the abbot's orders, and even to act without his orders was sometimes considered a transgression. Examples among the Egyptian monks of this submission to the commands of the superiors, exalted into a virtue by those who regarded the entire crushing of the individual will as a goal, are detailed by Cassian and others, e.g. a monk watering a dry stick, day after day, for months, or endeavoring to remove a huge rock immensely exceeding his powers. Appointments When a vacancy occurred, the bishop of the diocese chose the abbot out of the monks of the monastery, but the right of election was transferred by jurisdiction to the monks themselves, reserving to the bishop the confirmation of the election and the benediction of the new abbot. In abbeys exempt from the archbishop's diocesan jurisdiction, the confirmation and benediction had to be conferred by the pope in person, the house being taxed with the expenses of the new abbot's journey to Rome. It was necessary that an abbot should be at least 30 years of age, of legitimate birth, a monk of the house for at least 10 years, unless it furnished no suitable candidate, when a liberty was allowed of electing from another monastery, well instructed himself, and able to instruct others, one also who had learned how to command by having practised obedience. In some exceptional cases an abbot was allowed to name his own successor. Cassian speaks of an abbot in Egypt doing this; and in later times we have another example in the case of St Bruno. Popes and sovereigns gradually encroached on the rights of the monks, until in Italy the pope had usurped the nomination of all abbots, and the king in France, with the exception of Cluny, Premontré and other houses, chiefs of their order. The election was for life, unless the abbot was canonically deprived by the chiefs of his order, or when he was directly subject to them, by the pope or the bishop, and also in England it was for a term of 8–12 years. The ceremony of the formal admission of a Benedictine abbot in medieval times is thus prescribed by the consuetudinary of Abingdon. The newly elected abbot was to put off his shoes at the door of the church, and proceed barefoot to meet the members of the house advancing in a procession. After proceeding up the nave, he was to kneel and pray at the topmost step of the entrance of the choir, into which he was to be introduced by the bishop or his commissary, and placed in his stall. The monks, then kneeling, gave him the kiss of peace on the hand, and rising, on the mouth, the abbot holding his staff of office. He then put on his shoes in the vestry, and a chapter was held, and the bishop or his delegate preached a suitable sermon. General information Before the late modern era, the abbot was treated with the utmost reverence by the brethren of his house. When he appeared either in church or chapter all present rose and bowed. His letters were received kneeling, as were those of the pope and the king. No monk might sit in his presence, or leave it without his permission, reflecting the hierarchical etiquette of families and society. The highest place was assigned to him, both in church and at table. In the East he was commanded to eat with the other monks. In the West the Rule of St Benedict appointed him a separate table, at which he might entertain guests and strangers. Because this permission opened the door to luxurious living, Synods of Aachen (816–819), decreed that the abbot should dine in the refectory, and be content with the ordinary fare of the monks, unless he had to entertain a guest. These ordinances proved, however, generally ineffectual to secure strictness of diet, and contemporaneous literature abounds with satirical remarks and complaints concerning the inordinate extravagance of the tables of the abbots. When the abbot condescended to dine in the refectory, his chaplains waited upon him with the dishes, a servant, if necessary, assisting them. When abbots dined in their own private hall, the Rule of St Benedict charged them to invite their monks to their table, provided there was room, on which occasions the guests were to abstain from quarrels, slanderous talk and idle gossiping. The ordinary attire of the abbot was according to rule to be the same as that of the monks. But by the 10th century the rule was commonly set aside, and we find frequent complaints of abbots dressing in silk, and adopting sumptuous attire. Some even laid aside the monastic habit altogether, and assumed a secular dress. With the increase of wealth and power, abbots had lost much of their special religious character, and become great lords, chiefly distinguished from lay lords by celibacy. Thus we hear of abbots going out to hunt, with their men carrying bows and arrows; keeping horses, dogs and huntsmen; and special mention is made of an abbot of Leicester, c. 1360, who was the most skilled of all the nobility in hare hunting. In magnificence of equipage and retinue the abbots vied with the first nobles of the realm. They rode on mules with gilded bridles, rich saddles and housings, carrying hawks on their wrist, followed by an immense train of attendants. The bells of the churches were rung as they passed. They associated on equal terms with laymen of the highest distinction, and shared all their pleasures and pursuits. This rank and power was, however, often used most beneficially. For instance, we read of Richard Whiting, the last abbot of Glastonbury, judicially murdered by Henry VIII, that his house was a kind of well-ordered court, where as many as 300 sons of noblemen and gentlemen, who had been sent to him for virtuous education, had been brought up, besides others of a lesser rank, whom he fitted for the universities. His table, attendance and officers were an honour to the nation. He would entertain as many as 500 persons of rank at one time, besides relieving the poor of the vicinity twice a week. He had his country houses and fisheries, and when he travelled to attend parliament his retinue amounted to upwards of 100 persons. The abbots of Cluny and Vendôme were, by virtue of their office, cardinals of the Roman church. In the process of time, the title abbot was extended to clerics who had no connection with the monastic system, as to the principal of a body of parochial clergy; and under the Carolingians to the chief chaplain of the king, , or military chaplain of the emperor, It even came to be adopted by purely secular officials. Thus the chief magistrate of the republic at Genoa was called . Lay abbots (M. Lat. , , , , or , , or sometimes simply ) were the outcome of the growth of the feudal system from the 8th century onwards. The practice of commendation, by which—to meet a contemporary emergency—the revenues of the community were handed over to a lay lord, in return for his protection, early suggested to the emperors and kings the expedient of rewarding their warriors with rich abbeys held in commendam. During the Carolingian epoch, the custom grew up of granting these as regular heritable fiefs or benefices, and by the 10th century, before the great Cluniac reform, the system was firmly established. Even the abbey of St Denis was held in commendam by Hugh Capet. The example of the kings was followed by the feudal nobles, sometimes by making a temporary concession permanent, sometimes without any form of commendation whatever. In England the abuse was rife in the 8th century, as may be gathered from the acts of the council of Cloveshoe. These lay abbacies were not merely a question of overlordship, but implied the concentration in lay hands of all the rights, immunities and jurisdiction of the foundations, i.e. the more or less complete secularization of spiritual institutions. The lay abbot took his recognized rank in the feudal hierarchy, and was free to dispose of his fief as in the case of any other. The enfeoffment of abbeys differed in form and degree. Sometimes the monks were directly subject to the lay abbot; sometimes he appointed a substitute to perform the spiritual functions, known usually as dean (), but also as abbot (, , ). When the great reform of the 11th century had put an end to the direct jurisdiction of the lay abbots, the honorary title of abbot continued to be held by certain of the great feudal families, as late as the 13th century and later, with the head of the community retaining the title of dean. The connection of the lesser lay abbots with the abbeys, especially in the south of France, lasted longer; and certain feudal families retained the title of () for centuries, together with certain rights over the abbey lands or revenues. The abuse was not confined to the West. John, patriarch of Antioch at the beginning of the 12th century, informs us that in his time most monasteries had been handed over to laymen, , for life, or for part of their lives, by the emperors. Giraldus Cambrensis reported (Itinerary, ii.iv) the common customs of lay abbots in the late 12th-century Church of Wales: In conventual cathedrals, where the bishop occupied the place of the abbot, the functions usually devolving on the superior of the monastery were performed by a prior. Modern practices In the Roman Catholic Church, abbots continue to be elected by the monks of an abbey to lead them as their religious superior in those orders and monasteries that make use of the term (some orders of monks, as the Carthusians for instance, have no abbots, only priors). A monastery must have been granted the status of an abbey by the pope, and such monasteries are normally raised to this level after showing a degree of stability—a certain number of monks in vows, a certain number of years of establishment, a certain firmness to the foundation in economic, vocational and legal aspects. Prior to this, the monastery would be a mere priory, headed by a prior who acts as superior but without the same degree of legal authority that an abbot has. The abbot is chosen by the monks from among the fully professed monks. Once chosen, he must request blessing: the blessing of an abbot is celebrated by the bishop in whose diocese the monastery is or, with his permission, another abbot or bishop. The ceremony of such a blessing is similar in some aspects to the consecration of a bishop, with the new abbot being presented with the mitre, the ring, and the crosier as symbols of office and receiving the laying on of hands and blessing from the celebrant. Though the ceremony installs the new abbot into a position of legal authority, it does not confer further sacramental authority- it is not a further degree of Holy Orders (although some abbots have been ordained to the episcopacy). Once he has received this blessing, the abbot not only becomes father of his monks in a spiritual sense, but their major superior under canon law, and has the additional authority to confer the ministries of acolyte and lector (formerly, he could confer the minor orders, which are not sacraments, that these ministries have replaced). The abbey is a species of "exempt religious" in that it is, for the most part, answerable to the pope, or to the abbot primate, rather than to the local bishop. The abbot wears the same habit as his fellow monks, though by tradition he adds to it a pectoral cross. Territorial abbots follow all of the above, but in addition must receive a mandate of authority from the pope over the territory around the monastery for which they are responsible. Abbatial hierarchy In some monastic families, there is a hierarchy of precedence or authority among abbots. In some cases, this is the result of an abbey being considered the "mother" of several "daughter" abbeys founded as dependent priories of the "mother." In other cases, abbeys have affiliated in networks known as "congregations." Some monastic families recognize one abbey as the motherhouse of the entire order. The abbot of Sant'Anselmo di Aventino, in Rome, is styled the "abbot primate," and is acknowledged the senior abbot for the Order of St. Benedict (O.S.B.) An abbot president is the head of a congregation (federation) of abbeys within the Order of St. Benedict (for instance, the English Congregation, The American Cassinese Congregation, etc.), or of the Cistercians (O. Cist.) An archabbot is the head of some monasteries which are the motherhouses of other monasteries (for instance, Saint Vincent Archabbey, Latrobe, Pennsylvania) Mauro-Giuseppe Lepori O. Cist. is the current Abbot General of the Cistercians of the Common Observance. Modern abbots not as superior The title abbé (French; Ital. abate), as commonly used in the Catholic Church on the European continent, is the equivalent of the English "Father" (parallel etymology), being loosely applied to all who have received the tonsure. This use of the title is said to have originated in the right conceded to the king of France, by the concordat between Pope Leo X and Francis I (1516), to appoint commendatory abbots () to most of the abbeys in France. The expectation of obtaining these sinecures drew young men towards the church in considerable numbers, and the class of abbés so formed - they were sometimes called, and sometimes (ironically) ("abbés of holy hope; or in a jeu de mots, "of St. Hope") - came to hold a recognized position. The connection many of them had with the church was of the slenderest kind, consisting mainly in adopting the title of abbé, after a remarkably moderate course of theological study, practising celibacy and wearing distinctive dress, a short dark-violet coat with narrow collar. Being men of presumed learning and undoubted leisure, many of the class found admission to the houses of the French nobility as tutors or advisers. Nearly every great family had its abbé. The class did not survive the Revolution; but the courtesy title of abbé, having long lost all connection in people's minds with any special ecclesiastical function, remained as a convenient general term applicable to any clergyman. Eastern Christian In the Eastern Orthodox and Eastern Catholic Churches, the abbot is referred to as the hegumen. The Superior of a monastery of nuns is called the Hēguménē. The title of archimandrite (literally the head of the enclosure) used to mean something similar. In the East, the principle set forth in the Corpus Juris Civilis still applies, whereby most abbots are immediately subject to the local bishop. Those monasteries which enjoy the status of being stauropegic will be subject only to a primate or his Synod of Bishops and not the local bishop. Honorary and other uses of the title Although currently in the Western Church the title "abbot" is given only abbots of monasteries, the title archimandrite is given to "monastics" (i.e., celibate) priests in the East, even when not attached to a monastery, as an honor for service, similar to the title of monsignor in the Western/Latin Rite of the Catholic Church. In the Eastern Orthodox Church, only monastics are permitted to be elevated to the rank of archimandrite. Married priests are elevated to the parallel rank of Archpriest or Protopresbyter. Normally there are no celibate priests who are not monastics in the Orthodox Church, with the exception of married priests who have been widowed. Since the time of Catherine II the ranks of Abbot and Archimandrite have been given as honorary titles in the Russian Church, and may be given to any monastic, even if he does not in fact serve as the superior of a monastery. In Greek practice the title or function of Abbot corresponds to a person who serves as the head of a monastery, although the title of the Archimandrite may be given to any celibate priest who could serve as the head of a monastery. In the German Evangelical Church, the German title of Abt (abbot) is sometimes bestowed, like the French abbé, as an honorary distinction, and survives to designate the heads of some monasteries converted at the Reformation into collegiate foundations. Of these the most noteworthy is Loccum Abbey in Hanover, founded as a Cistercian house in 1163 by Count Wilbrand of Hallermund, and reformed in 1593. The abbot of Loccum, who still carries a pastoral staff, takes precedence over all the clergy of Hanover, and was ex officio a member of the consistory of the kingdom. The governing body of the abbey consists of the abbot, prior and the "convent", or community, of Stiftsherren (canons). In the Church of England, the Bishop of Norwich, by royal decree given by Henry VIII, also holds the honorary title of "Abbot of St. Benet." This title hails back to England's separation from the See of Rome, when King Henry, as supreme head of the newly independent church, took over all of the monasteries, mainly for their possessions, except for St. Benet, which he spared because the abbot and his monks possessed no wealth, and lived like simple beggars, deposing the incumbent Bishop of Norwich and seating the abbot in his place, thus the dual title still held to this day. Additionally, at the enthronement of the Archbishop of Canterbury, there is a threefold enthronement, once in the throne the chancel as the diocesan bishop of Canterbury, once in the Chair of St. Augustine as the Primate of All England, and then once in the chapter-house as Titular Abbot of Canterbury. There are several Benedictine abbeys throughout the Anglican Communion. Most of them have mitred abbots. Abbots in art and literature "The Abbot" is one of the archetypes traditionally illustrated in scenes of Danse Macabre. The lives of numerous abbots make up a significant contribution to Christian hagiography, one of the most well-known being the Life of St. Benedict of Nursia by St. Gregory the Great. During the years 1106–1107 AD, Daniel, a Russian Orthodox abbot, made a pilgrimage to the Holy Land and recorded his experiences. His diary was much-read throughout Russia, and at least seventy-five manuscript copies survive. Saint Joseph, Abbot of Volokolamsk, Russia (1439–1515), wrote a number of influential works against heresy, and about monastic and liturgical discipline, and Christian philanthropy. In the Tales of Redwall series, the creatures of Redwall are led by an abbot or abbess. These "abbots" are appointed by the brothers and sisters of Redwall to serve as a superior and provide paternal care, much like real abbots. "The Abbot" was a nickname of RZA from the Wu-Tang Clan.

In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves may also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection. Angle is also used to designate the measure of an angle or of a rotation. This measure is the ratio of the length of a circular arc to its radius. In the case of a geometric angle, the arc is centered at the vertex and delimited by the sides. In the case of a rotation, the arc is centered at the center of the rotation and delimited by any other point and its image by the rotation. History and etymology The word angle comes from the Latin word angulus, meaning "corner"; cognate words are the Greek (ankylοs), meaning "crooked, curved," and the English word "ankle". Both are connected with the Proto-Indo-European root *ank-, meaning "to bend" or "bow". Euclid defines a plane angle as the inclination to each other, in a plane, of two lines which meet each other, and do not lie straight with respect to each other. According to Proclus, an angle must be either a quality or a quantity, or a relationship. The first concept was used by Eudemus, who regarded an angle as a deviation from a straight line; the second by Carpus of Antioch, who regarded it as the interval or space between the intersecting lines; Euclid adopted the third concept. Identifying angles In mathematical expressions, it is common to use Greek letters (α, β, γ, θ, φ, . . . ) as variables denoting the size of some angle (to avoid confusion with its other meaning, the symbol is typically not used for this purpose). Lower case Roman letters (a, b, c, . . . ) are also used, as are upper case Roman letters in the context of polygons. See the figures in this article for examples. In geometric figures, angles may also be identified by the labels attached to the three points that define them. For example, the angle at vertex A enclosed by the rays AB and AC (i.e. the lines from point A to point B and point A to point C) is denoted ∠BAC (in Unicode ) or . Where there is no risk of confusion, the angle may sometimes be referred to simply by its vertex (in this case "angle A"). Potentially, an angle denoted as, say, ∠BAC, might refer to any of four angles: the clockwise angle from B to C, the anticlockwise angle from B to C, the clockwise angle from C to B, or the anticlockwise angle from C to B, where the direction in which the angle is measured determines its sign (see Positive and negative angles). However, in many geometrical situations, it is obvious from context that the positive angle less than or equal to 180 degrees is meant, in which case no ambiguity arises. Otherwise, a convention may be adopted so that ∠BAC always refers to the anticlockwise (positive) angle from B to C, and ∠CAB the anticlockwise (positive) angle from C to B. Types of angles Individual angles There is some common terminology for angles, whose measure is always non-negative (see ): An angle equal to 0° or not turned is called a zero angle. An angle smaller than a right angle (less than 90°) is called an acute angle ("acute" meaning "sharp"). An angle equal to  turn (90° or radians) is called a right angle. Two lines that form a right angle are said to be normal, orthogonal, or perpendicular. An angle larger than a right angle and smaller than a straight angle (between 90° and 180°) is called an obtuse angle ("obtuse" meaning "blunt"). An angle equal to  turn (180° or radians) is called a straight angle. An angle larger than a straight angle but less than 1 turn (between 180° and 360°) is called a reflex angle. An angle equal to 1 turn (360° or 2 radians) is called a full angle, complete angle, round angle or a perigon. An angle that is not a multiple of a right angle is called an oblique angle. The names, intervals, and measuring units are shown in the table below: Equivalence angle pairs Angles that have the same measure (i.e. the same magnitude) are said to be equal or congruent. An angle is defined by its measure and is not dependent upon the lengths of the sides of the angle (e.g. all right angles are equal in measure). Two angles that share terminal sides, but differ in size by an integer multiple of a turn, are called coterminal angles. A reference angle is the acute version of any angle determined by repeatedly subtracting or adding straight angle ( turn, 180°, or radians), to the results as necessary, until the magnitude of the result is an acute angle, a value between 0 and turn, 90°, or radians. For example, an angle of 30 degrees has a reference angle of 30 degrees, and an angle of 150 degrees also has a reference angle of 30 degrees (180–150). An angle of 750 degrees has a reference angle of 30 degrees (750–720). Vertical and adjacent angle pairs When two straight lines intersect at a point, four angles are formed. Pairwise these angles are named according to their location relative to each other. A pair of angles opposite each other, formed by two intersecting straight lines that form an "X"-like shape, are called vertical angles or opposite angles or vertically opposite angles. They are abbreviated as vert. opp. ∠s. The equality of vertically opposite angles is called the vertical angle theorem. Eudemus of Rhodes attributed the proof to Thales of Miletus. The proposition showed that since both of a pair of vertical angles are supplementary to both of the adjacent angles, the vertical angles are equal in measure. According to a historical note, when Thales visited Egypt, he observed that whenever the Egyptians drew two intersecting lines, they would measure the vertical angles to make sure that they were equal. Thales concluded that one could prove that all vertical angles are equal if one accepted some general notions such as: All straight angles are equal. Equals added to equals are equal. Equals subtracted from equals are equal. When two adjacent angles form a straight line, they are supplementary. Therefore, if we assume that the measure of angle A equals x, then the measure of angle C would be . Similarly, the measure of angle D would be . Both angle C and angle D have measures equal to and are congruent. Since angle B is supplementary to both angles C and D, either of these angle measures may be used to determine the measure of Angle B. Using the measure of either angle C or angle D, we find the measure of angle B to be . Therefore, both angle A and angle B have measures equal to x and are equal in measure. Adjacent angles, often abbreviated as adj. ∠s, are angles that share a common vertex and edge but do not share any interior points. In other words, they are angles that are side by side, or adjacent, sharing an "arm". Adjacent angles which sum to a right angle, straight angle, or full angle are special and are respectively called complementary, supplementary and explementary angles (see below). A transversal is a line that intersects a pair of (often parallel) lines, and is associated with alternate interior angles, corresponding angles, interior angles, and exterior angles. Combining angle pairs Three special angle pairs involve the summation of angles: Complementary angles are angle pairs whose measures sum to one right angle ( turn, 90°, or radians). If the two complementary angles are adjacent, their non-shared sides form a right angle. In Euclidean geometry, the two acute angles in a right triangle are complementary, because the sum of internal angles of a triangle is 180 degrees, and the right angle itself accounts for 90 degrees. The adjective complementary is from Latin complementum, associated with the verb complere, "to fill up". An acute angle is "filled up" by its complement to form a right angle. The difference between an angle and a right angle is termed the complement of the angle. If angles A and B are complementary, the following relationships hold: (The tangent of an angle equals the cotangent of its complement and its secant equals the cosecant of its complement.) The prefix "co-" in the names of some trigonometric ratios refers to the word "complementary". Two angles that sum to a straight angle ( turn, 180°, or radians) are called supplementary angles. If the two supplementary angles are adjacent (i.e. have a common vertex and share just one side), their non-shared sides form a straight line. Such angles are called a linear pair of angles. However, supplementary angles do not have to be on the same line, and can be separated in space. For example, adjacent angles of a parallelogram are supplementary, and opposite angles of a cyclic quadrilateral (one whose vertices all fall on a single circle) are supplementary. If a point P is exterior to a circle with center O, and if the tangent lines from P touch the circle at points T and Q, then ∠TPQ and ∠TOQ are supplementary. The sines of supplementary angles are equal. Their cosines and tangents (unless undefined) are equal in magnitude but have opposite signs. In Euclidean geometry, any sum of two angles in a triangle is supplementary to the third, because the sum of internal angles of a triangle is a straight angle. Two angles that sum to a complete angle (1 turn, 360°, or 2 radians) are called explementary angles or conjugate angles. The difference between an angle and a complete angle is termed the explement of the angle or conjugate of an angle. Polygon-related angles An angle that is part of a simple polygon is called an interior angle if it lies on the inside of that simple polygon. A simple concave polygon has at least one interior angle that is a reflex angle. In Euclidean geometry, the measures of the interior angles of a triangle add up to radians, 180°, or turn; the measures of the interior angles of a simple convex quadrilateral add up to 2 radians, 360°, or 1 turn. In general, the measures of the interior angles of a simple convex polygon with n sides add up to (n − 2) radians, or (n − 2)180 degrees, (n − 2)2 right angles, or (n − 2) turn. The supplement of an interior angle is called an exterior angle, that is, an interior angle and an exterior angle form a linear pair of angles. There are two exterior angles at each vertex of the polygon, each determined by extending one of the two sides of the polygon that meet at the vertex; these two angles are vertical and hence are equal. An exterior angle measures the amount of rotation one has to make at a vertex to trace out the polygon. If the corresponding interior angle is a reflex angle, the exterior angle should be considered negative. Even in a non-simple polygon it may be possible to define the exterior angle, but one will have to pick an orientation of the plane (or surface) to decide the sign of the exterior angle measure. In Euclidean geometry, the sum of the exterior angles of a simple convex polygon, if only one of the two exterior angles is assumed at each vertex, will be one full turn (360°). The exterior angle here could be called a supplementary exterior angle. Exterior angles are commonly used in Logo Turtle programs when drawing regular polygons. In a triangle, the bisectors of two exterior angles and the bisector of the other interior angle are concurrent (meet at a single point). In a triangle, three intersection points, each of an external angle bisector with the opposite extended side, are collinear. In a triangle, three intersection points, two of them between an interior angle bisector and the opposite side, and the third between the other exterior angle bisector and the opposite side extended, are collinear. Some authors use the name exterior angle of a simple polygon to simply mean the explement exterior angle (not supplement!) of the interior angle. This conflicts with the above usage. Plane-related angles The angle between two planes (such as two adjacent faces of a polyhedron) is called a dihedral angle. It may be defined as the acute angle between two lines normal to the planes. The angle between a plane and an intersecting straight line is equal to ninety degrees minus the angle between the intersecting line and the line that goes through the point of intersection and is normal to the plane. Measuring angles The size of a geometric angle is usually characterized by the magnitude of the smallest rotation that maps one of the rays into the other. Angles that have the same size are said to be equal or congruent or equal in measure. In some contexts, such as identifying a point on a circle or describing the orientation of an object in two dimensions relative to a reference orientation, angles that differ by an exact multiple of a full turn are effectively equivalent. In other contexts, such as identifying a point on a spiral curve or describing the cumulative rotation of an object in two dimensions relative to a reference orientation, angles that differ by a non-zero multiple of a full turn are not equivalent. In order to measure an angle θ, a circular arc centered at the vertex of the angle is drawn, e.g. with a pair of compasses. The ratio of the length s of the arc by the radius r of the circle is the number of radians in the angle. Conventionally, in mathematics and in the SI, the radian is treated as being equal to the dimensionless value 1. The angle expressed another angular unit may then be obtained by multiplying the angle by a suitable conversion constant of the form , where k is the measure of a complete turn expressed in the chosen unit (for example, for degrees or 400 grad for gradians): The value of thus defined is independent of the size of the circle: if the length of the radius is changed then the arc length changes in the same proportion, so the ratio s/r is unaltered. In particular, the measure of angle is radian can be also interpreted as the arc length of its corresponding unit circle: Angle addition postulate The angle addition postulate states that if B is in the interior of angle AOC, then The measure of the angle AOC is the sum of the measure of angle AOB and the measure of angle BOC. Units Throughout history, angles have been measured in various units. These are known as angular units, with the most contemporary units being the degree ( ° ), the radian (rad), and the gradian (grad), though many others have been used throughout history. In the International System of Quantities, angle is defined as a dimensionless quantity. This impacts how angle is treated in dimensional analysis. Most units of angular measurement are defined such that one turn (i.e. one full circle) is equal to n units, for some whole number n. Two exceptions are the radian (and its decimal submultiples) and the diameter part. One radian is the angle subtended by an arc of a circle that has the same length as the circle's radius. The radian is the derived unit of angular measurement in the SI system. By definition, it is dimensionless, though it may be specified as rad to avoid ambiguity. Angles measured in degrees, are shown with the symbol °. Subdivisions of the degree are minute (symbol ′, 1′ = 1/60°) and second (symbol ″, 1″ = 1/3600°). An angle of 360° corresponds to the angle subtended by a full circle, and is equal to radians, or 400 gradians. Other units used to represent angles are listed in the following table. These units are defined such that the number of turns is equivalent to a full circle. Other descriptors Hour angle (n = 24): The astronomical hour angle is  turn. As this system is amenable to measuring objects that cycle once per day (such as the relative position of stars), the sexagesimal subunits are called minute of time and second of time. These are distinct from, and 15 times larger than, minutes and seconds of arc. 1 hour = 15° =  rad =  quad =  turn =  grad. (Compass) point or wind (n = 32): The point, used in navigation, is of a turn. 1 point = of a right angle = 11.25° = 12.5 grad. Each point is subdivided in four quarter-points so that 1 turn equals 128 quarter-points. Pechus (n = 144–180): The pechus was a Babylonian unit equal to about 2° or °. Tau, the number of radians in one turn (1 turn = rad), . Diameter part (n = 376.99...): The diameter part (occasionally used in Islamic mathematics) is radian. One "diameter part" is approximately 0.95493°. There are about 376.991 diameter parts per turn. Milliradian and derived definitions: The true milliradian is defined a thousandth of a radian, which means that a rotation of one turn would equal exactly 2000π mil (or approximately 6283.185 mil), and almost all scope sights for firearms are calibrated to this definition. In addition there are three other derived definitions used for artillery and navigation which are approximately equal to a milliradian. Under these three other definitions one turn makes up for exactly 6000, 6300 or 6400 mils, which equals spanning the range from 0.05625 to 0.06 degrees (3.375 to 3.6 minutes). In comparison, the true milliradian is approximately 0.05729578 degrees (3.43775 minutes). One "NATO mil" is defined as of a circle. Just like with the true milliradian, each of the other definitions exploits the mil's useful property of subtensions, i.e. that the value of one milliradian approximately equals the angle subtended by a width of 1 meter as seen from 1 km away ( = 0.0009817... ≈ ). Akhnam and zam. In old Arabia a turn was subdivided in 32 Akhnam and each akhnam was subdivided in 7 zam, so that a turn is 224 zam. Signed angles Although the definition of the measurement of an angle does not support the concept of a negative angle, it is frequently useful to impose a convention that allows positive and negative angular values to represent orientations and/or rotations in opposite directions relative to some reference. In a two-dimensional Cartesian coordinate system, an angle is typically defined by its two sides, with its vertex at the origin. The initial side is on the positive x-axis, while the other side or terminal side is defined by the measure from the initial side in radians, degrees, or turns. With positive angles representing rotations toward the positive y-axis and negative angles representing rotations toward the negative y-axis. When Cartesian coordinates are represented by standard position, defined by the x-axis rightward and the y-axis upward, positive rotations are anticlockwise and negative rotations are clockwise. In many contexts, an angle of −θ is effectively equivalent to an angle of "one full turn minus θ". For example, an orientation represented as −45° is effectively equivalent to an orientation represented as 360° − 45° or 315°. Although the final position is the same, a physical rotation (movement) of −45° is not the same as a rotation of 315° (for example, the rotation of a person holding a broom resting on a dusty floor would leave visually different traces of swept regions on the floor). In three-dimensional geometry, "clockwise" and "anticlockwise" have no absolute meaning, so the direction of positive and negative angles must be defined relative to some reference, which is typically a vector passing through the angle's vertex and perpendicular to the plane in which the rays of the angle lie. In navigation, bearings or azimuth are measured relative to north. By convention, viewed from above, bearing angles are positive clockwise, so a bearing of 45° corresponds to a north-east orientation. Negative bearings are not used in navigation, so a north-west orientation corresponds to a bearing of 315°. Alternative ways of measuring the size of an angle There are several alternatives to measuring the size of an angle by the angle of rotation. The slope or gradient is equal to the tangent of the angle, or sometimes (rarely) the sine; a gradient is often expressed as a percentage. For very small values (less than 5%), the grade of a slope is approximately the measure of the angle in radians. In rational geometry the spread between two lines is defined as the square of the sine of the angle between the lines. As the sine of an angle and the sine of its supplementary angle are the same, any angle of rotation that maps one of the lines into the other leads to the same value for the spread between the lines. Astronomical approximations Astronomers measure angular separation of objects in degrees from their point of observation. 0.5° is approximately the width of the sun or moon. 1° is approximately the width of a little finger at arm's length. 10° is approximately the width of a closed fist at arm's length. 20° is approximately the width of a handspan at arm's length. These measurements clearly depend on the individual subject, and the above should be treated as rough rule of thumb approximations only. In astronomy, right ascension and declination are usually measured in angular units, expressed in terms of time, based on a 24-hour day. Measurements that are not angular units Not all angle measurements are angular units, for an angular measurement, it is definitional that the angle addition postulate holds. Some angle measurements where the angle addition postulate does not hold include: Trigonometric functions Slope Angles between curves The angle between a line and a curve (mixed angle) or between two intersecting curves (curvilinear angle) is defined to be the angle between the tangents at the point of intersection. Various names (now rarely, if ever, used) have been given to particular cases:—amphicyrtic (Gr. , on both sides, κυρτός, convex) or cissoidal (Gr. κισσός, ivy), biconvex; xystroidal or sistroidal (Gr. ξυστρίς, a tool for scraping), concavo-convex; amphicoelic (Gr. κοίλη, a hollow) or angulus lunularis, biconcave. Bisecting and trisecting angles The ancient Greek mathematicians knew how to bisect an angle (divide it into two angles of equal measure) using only a compass and straightedge, but could only trisect certain angles. In 1837, Pierre Wantzel showed that for most angles this construction cannot be performed. Dot product and generalisations In the Euclidean space, the angle θ between two Euclidean vectors u and v is related to their dot product and their lengths by the formula This formula supplies an easy method to find the angle between two planes (or curved surfaces) from their normal vectors and between skew lines from their vector equations. Inner product To define angles in an abstract real inner product space, we replace the Euclidean dot product ( · ) by the inner product , i.e. In a complex inner product space, the expression for the cosine above may give non-real values, so it is replaced with or, more commonly, using the absolute value, with The latter definition ignores the direction of the vectors and thus describes the angle between one-dimensional subspaces and spanned by the vectors and correspondingly. Angles between subspaces The definition of the angle between one-dimensional subspaces and given by in a Hilbert space can be extended to subspaces of any finite dimensions. Given two subspaces , with , this leads to a definition of angles called canonical or principal angles between subspaces. Angles in Riemannian geometry In Riemannian geometry, the metric tensor is used to define the angle between two tangents. Where U and V are tangent vectors and gij are the components of the metric tensor G, Hyperbolic angle A hyperbolic angle is an argument of a hyperbolic function just as the circular angle is the argument of a circular function. The comparison can be visualized as the size of the openings of a hyperbolic sector and a circular sector since the areas of these sectors correspond to the angle magnitudes in each case. Unlike the circular angle, the hyperbolic angle is unbounded. When the circular and hyperbolic functions are viewed as infinite series in their angle argument, the circular ones are just alternating series forms of the hyperbolic functions. This weaving of the two types of angle and function was explained by Leonhard Euler in Introduction to the Analysis of the Infinite. Angles in geography and astronomy In geography, the location of any point on the Earth can be identified using a geographic coordinate system. This system specifies the latitude and longitude of any location in terms of angles subtended at the center of the Earth, using the equator and (usually) the Greenwich meridian as references. In astronomy, a given point on the celestial sphere (that is, the apparent position of an astronomical object) can be identified using any of several astronomical coordinate systems, where the references vary according to the particular system. Astronomers measure the angular separation of two stars by imagining two lines through the center of the Earth, each intersecting one of the stars. The angle between those lines can be measured and is the angular separation between the two stars. In both geography and astronomy, a sighting direction can be specified in terms of a vertical angle such as altitude /elevation with respect to the horizon as well as the azimuth with respect to north. Astronomers also measure the apparent size of objects as an angular diameter. For example, the full moon has an angular diameter of approximately 0.5°, when viewed from Earth. One could say, "The Moon's diameter subtends an angle of half a degree." The small-angle formula can be used to convert such an angular measurement into a distance/size ratio.

Kim Renard Nazel (born June 17, 1965), better known by his stage names Arabian Prince or Professor X, is an American rapper, singer, songwriter, record producer, and DJ. He is best known as a founding member of N.W.A. Early life Nazel was born in Compton, California to the son of Joseph "Skippy" Nazel Jr., a prominent African-American author and radio talk show host. His musical background came from his mother, a piano teacher and classical musician. His family tried its best to shelter him, sending him to a Catholic school and keeping him busy with football to keep him away from the gangs. The younger Nazel got his first experience with making music at the radio station his father hosted his talk show on; Nazel used the radio station's equipment to put together mixtapes that he would sell at school. Nazel went on to graduate from Junípero Serra High School in nearby Gardena. Music career Nazel took the stage name of DJ Prince and started selling mixtapes at school. While working at a luggage store at the Del Amo Mall, its owner Sam Nassif asked him to DJ a party at a community center. He kept performing there for several weekends and the success persuaded Nassif to invest even more in the place, renaming it "The Cave", where Nazel would continue to host for over three years and even after his N.W.A. days. Nassif also funded DJ Prince's first record, "Strange Life". He changed his stage name when he was 15 years old at the Skateland USA, the same skating venue credited for launching the NWA a few years later, due to a fan's suggestion. He said about his name: Arabian Prince started working with Bobby Jimmy & the Critters in 1984. He also produced the hit single and album for J.J. Fad, "Supersonic". In 1986, he was a founding member of N.W.A, but soon after fellow member Ice Cube came back from the Phoenix Institute of Technology in 1988, Arabian Prince left over royalty and contract disagreements. "I started off as a solo artist", he said, "so I was aware of what a royalty statement was. I knew that when these many records were sold, there is a quarterly statement. When you look at it, you can see how much money was paid and then share it. This was not the case. We were also never paid for touring." Eazy-E, Ice Cube and MC Ren remained as the main performers, DJ Yella was the turntablist and Dr. Dre was the main producer. After leaving N.W.A, Arabian Prince began a solo career. His first album, Brother Arab, was released in 1989 with the single "She's Got A Big Posse"; Where's My Bytches followed in 1993. In the mid-2000s, he started releasing music again, with his Professor X project on the Dutch label Clone Records. "I could not release the record under Arabian Prince", he said, "because I already had a single out, so I called myself Professor X on that record." In 2007, he performed as a DJ on the 2K Sports Holiday Bounce Tour with artists from the Stones Throw label. In 2008, Stones Throw released a compilation of his electro-rap material from the 1980s. One of his songs was included on the 2007 video game, College Hoops 2K8. In 2015, a biopic about N.W.A. titled Straight Outta Compton was released; however, Arabian Prince was not portrayed in the film, and his role was omitted completely. The following year, N.W.A. was inducted into the Rock and Roll Hall of Fame, but again, Arabian Prince was not included nor mentioned. In 2018, Arabian Prince appeared on the AmeriKKKant album of industrial-metal band Ministry. He made a second appearance on Ministry's 2021 album Moral Hygiene. Other ventures Aside from his music career, he worked in special effects, 3D animation and video games. Straight Outta Compton movie controversy After the release of the NWA film, Straight Outta Compton, in 2015, Arabian Prince said to VladTV: "A lot of the scenes in real life, I was there -I'm just not there in the film, which I'm like, if you're gonna write me out of a movie, shoot some other scenes. Don't write scenes where I was there." Some of the pivotal scenes would be choosing the name for the band, the tour and the infamous Detroit concert. He also remembers himself as the main opposer to Jerry Heller about the royalties and the money, a role that in the movie was instead given to Ice Cube.

An army (from Latin arma "arms, weapons" via Old French armée, "armed" [feminine]), ground force or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or county. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army. In some countries, such as France and China, the term "army", especially in its plural form "armies", has the broader meaning of armed forces as a whole, while retaining the colloquial sense of land forces. To differentiate the colloquial army from the formal concept of military force, the term is qualified, for example in France the land force is called Armée de terre, meaning Land Army, and the air and space force is called Armée de l'Air et de l’Espace, meaning Air and Space Army. The naval force, although not using the term "army", is also included in the broad sense of the term "armies" — thus the French Navy is an integral component of the collective French Armies (French Armed Forces) under the Ministry of the Armies. A similar pattern is seen in China, with the People's Liberation Army (PLA) being the overall military, the land force being the PLA Ground Force, and so forth for the PLA Air Force, the PLA Navy, and other branches. By convention, irregular military is understood in contrast to regular armies which grew slowly from personal bodyguards or elite militia. Regular in this case refers to standardized doctrines, uniforms, organizations, etc. Regular military can also refer to full-time status (standing army), versus reserve or part-time personnel. Other distinctions may separate statutory forces (established under laws such as the National Defence Act), from de facto "non-statutory" forces such as some guerrilla and revolutionary armies. Armies may also be expeditionary (designed for overseas or international deployment) or fencible (designed for – or restricted to – homeland defence). History India India's armies were among the first in the world. The first recorded battle, the Battle of the Ten Kings, happened when a Hindu Aryan king named Sudas defeated an alliance of ten kings and their supportive chieftains. During the Iron Age, the Maurya and Nanda Empires had the largest armies in the world, the peak being approximately over 600,000 Infantry, 30,000 Cavalry, 8,000 War-Chariots and 9,000 War Elephants not including tributary state allies. In the Gupta age, large armies of longbowmen were recruited to fight off invading horse archer armies. Elephants, pikemen and cavalry were other featured troops. In Rajput times, the main piece of equipment was iron or chain-mail armor, a round shield, either a curved blade or a straight sword, a chakra disc, and a katar dagger. China The states of China raised armies for at least 1000 years before the Spring and Autumn Annals. By the Warring States period, the crossbow had been perfected enough to become a military secret, with bronze bolts that could pierce any armor. Thus any political power of a state rested on the armies and their organization. China underwent political consolidation of the states of Han (韓), Wei (魏), Chu (楚), Yan (燕), Zhao (趙) and Qi (齊), until by 221 BCE, Qin Shi Huang (秦始皇帝), the first emperor of the Qin dynasty, attained absolute power. This first emperor of China could command the creation of a Terracotta Army to guard his tomb in the city of Xi'an (西安), as well as a realignment of the Great Wall of China to strengthen his empire against insurrection, invasion and incursion. Sun Tzu's The Art of War remains one of China's Seven Military Classics, even though it is two thousand years old. Since no political figure could exist without an army, measures were taken to ensure only the most capable leaders could control the armies. Civil bureaucracies (士大夫) arose to control the productive power of the states, and their military power. Sparta The Spartan Army was one of the earliest known professional armies. Boys were sent to a barracks at the age of seven or eight to train for becoming a soldier. At the age of thirty, they were released from the barracks and allowed to marry and have a family. After that, men devoted their lives to war until their retirement at the age of 60. The Spartan Army was largely composed of hoplites, equipped with arms and armor nearly identical to each other. Each hoplite bore the Spartan emblem and a scarlet uniform. The main pieces of this armor were a round shield, a spear and a helmet. Ancient Rome The Roman Army had its origins in the citizen army of the Republic, which was staffed by citizens serving mandatory duty for Rome. Reforms turned the army into a professional organization which was still largely filled by citizens, but these citizens served continuously for 25 years before being discharged. The Romans were also noted for making use of auxiliary troops, non-Romans who served with the legions and filled roles that the traditional Roman military could not fill effectively, such as light skirmish troops and heavy cavalry. After their service in the army they were made citizens of Rome and then their children were citizens also. They were also given land and money to settle in Rome. In the Late Roman Empire, these auxiliary troops, along with foreign mercenaries, became the core of the Roman Army; moreover, by the time of the Late Roman Empire tribes such as the Visigoths were paid to serve as mercenaries. Medieval Europe In the earliest Middle Ages it was the obligation of every aristocrat to respond to the call to battle with his own equipment, archers, and infantry. This decentralized system was necessary due to the social order of the time, but could lead to motley forces with variable training, equipment and abilities. The more resources the noble had access to, the better his troops would be. Initially, the words "knight" and "noble" were used interchangeably as there was not generally a distinction between them. While the nobility did fight upon horseback, they were also supported by lower class citizens – and mercenaries and criminals – whose only purpose was participating in warfare because, most often than not, they held brief employment during their lord's engagement. As the Middle Ages progressed and feudalism developed in a legitimate social and economic system, knights started to develop into their own class with a minor caveat: they were still in debt to their lord. No longer primarily driven by economic need, the newly established vassal class were, instead, driven by fealty and chivalry. As central governments grew in power, a return to the citizen armies of the classical period also began, as central levies of the peasantry began to be the central recruiting tool. England was one of the most centralized states in the Middle Ages, and the armies that fought in the Hundred Years' War were, predominantly, composed of paid professionals. In theory, every Englishman had an obligation to serve for forty days. Forty days was not long enough for a campaign, especially one on the continent. Thus the scutage was introduced, whereby most Englishmen paid to escape their service and this money was used to create a permanent army. However, almost all high medieval armies in Europe were composed of a great deal of paid core troops, and there was a large mercenary market in Europe from at least the early 12th century. As the Middle Ages progressed in Italy, Italian cities began to rely mostly on mercenaries to do their fighting rather than the militias that had dominated the early and high medieval period in this region. These would be groups of career soldiers who would be paid a set rate. Mercenaries tended to be effective soldiers, especially in combination with standing forces, but in Italy they came to dominate the armies of the city states. This made them considerably less reliable than a standing army. Mercenary-on-mercenary warfare in Italy also led to relatively bloodless campaigns which relied as much on maneuver as on battles. In 1439 the French legislature, known as the Estates General (French: états généraux), passed laws that restricted military recruitment and training to the king alone. There was a new tax to be raised known as the taille that was to provide funding for a new Royal army. The mercenary companies were given a choice of either joining the Royal army as compagnies d'ordonnance on a permanent basis, or being hunted down and destroyed if they refused. France gained a total standing army of around 6,000 men, which was sent out to gradually eliminate the remaining mercenaries who insisted on operating on their own. The new standing army had a more disciplined and professional approach to warfare than its predecessors. The reforms of the 1440s, eventually led to the French victory at Castillon in 1453, and the conclusion of the Hundred Years' War. By 1450 the companies were divided into the field army, known as the grande ordonnance and the garrison force known as the petite ordonnance. Early modern First nation states lacked the funds needed to maintain standing forces, so they tended to hire mercenaries to serve in their armies during wartime. Such mercenaries typically formed at the ends of periods of conflict, when men-at-arms were no longer needed by their respective governments. The veteran soldiers thus looked for other forms of employment, often becoming mercenaries. Free Companies would often specialize in forms of combat that required longer periods of training that was not available in the form of a mobilized militia. As late as the 1650s, most troops were mercenaries. However, after the 17th century, most states invested in better disciplined and more politically reliable permanent troops. For a time mercenaries became important as trainers and administrators, but soon these tasks were also taken by the state. The massive size of these armies required a large supporting force of administrators. The newly centralized states were forced to set up vast organized bureaucracies to manage these armies, which some historians argue is the basis of the modern bureaucratic state. The combination of increased taxes and increased centralisation of government functions caused a series of revolts across Europe such as the Fronde in France and the English Civil War. In many countries, the resolution of this conflict was the rise of absolute monarchy. Only in England and the Netherlands did representative government evolve as an alternative. From the late 17th century, states learned how to finance wars through long term low interest loans from national banking institutions. The first state to master this process was the Dutch Republic. This transformation in the armies of Europe had great social impact. The defense of the state now rested on the commoners, not on the aristocrats. However, aristocrats continued to monopolise the officer corps of almost all early modern armies, including their high command. Moreover, popular revolts almost always failed unless they had the support and patronage of the noble or gentry classes. The new armies, because of their vast expense, were also dependent on taxation and the commercial classes who also began to demand a greater role in society. The great commercial powers of the Dutch and English matched much larger states in military might. As any man could be quickly trained in the use of a musket, it became far easier to form massive armies. The inaccuracy of the weapons necessitated large groups of massed soldiers. This led to a rapid swelling of the size of armies. For the first time huge masses of the population could enter combat, rather than just the highly skilled professionals. It has been argued that the drawing of men from across the nation into an organized corps helped breed national unity and patriotism, and during this period the modern notion of the nation state was born. However, this would only become apparent after the French Revolutionary Wars. At this time, the levée en masse and conscription would become the defining paradigm of modern warfare. Before then, however, most national armies were in fact composed of many nationalities. In Spain armies were recruited from all the Spanish European territories including Spain, Italy, Wallonia (Walloon Guards) and Germany. The French recruited some soldiers from Germany, Switzerland as well as from Piedmont. Britain recruited Hessian and Hanovrian troops until the late 18th century. Irish Catholics made careers for themselves in the armies of many Catholic European states. Prior to the English Civil War in England, the monarch maintained a personal bodyguard of Yeomen of the Guard and the Honourable Corps of Gentlemen at Arms, or "gentlemen pensioners", and a few locally raised companies to garrison important places such as Berwick on Tweed or Portsmouth (or Calais before it was recaptured by France in 1558). Troops for foreign expeditions were raised upon an ad hoc basis. Noblemen and professional regular soldiers were commissioned by the monarch to supply troops, raising their quotas by indenture from a variety of sources. On January 26, 1661 Charles II issued the Royal Warrant that created the genesis of what would become the British Army, although the Scottish and English Armies would remain two separate organizations until the unification of England and Scotland in 1707. The small force was represented by only a few regiments. After the American Revolutionary War the Continental Army was quickly disbanded as part of the Americans' distrust of standing armies, and irregular state militias became the sole ground army of the United States, with the exception of one battery of artillery guarding West Point's arsenal. Then First American Regiment was established in 1784. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army. The first of these, the Legion of the United States, was established in 1791. Until 1733 the common soldiers of Prussian Army consisted largely of peasantry recruited or impressed from Brandenburg–Prussia, leading many to flee to neighboring countries. To halt this trend, Frederick William I divided Prussia into regimental cantons. Every youth was required to serve as a soldier in these recruitment districts for three months each year; this met agrarian needs and added extra troops to bolster the regular ranks. Russian tsars before Peter I of Russia maintained professional hereditary musketeer corps (streltsy in Russian) that were highly unreliable and undisciplined. In times of war the armed forces were augmented by peasants. Peter I introduced a modern regular army built on German model, but with a new aspect: officers not necessarily from nobility, as talented commoners were given promotions that eventually included a noble title at the attainment of an officer's rank. Conscription of peasants and townspeople was based on quota system, per settlement. Initially it was based on the number of households, later it was based on the population numbers. The term of service in the 18th century was for life. In 1793 it was reduced to 25 years. In 1834 it was reduced to 20 years plus 5 years in reserve and in 1855 to 12 years plus 3 years of reserve. The first Ottoman standing army were Janissaries. They replaced forces that mostly comprised tribal warriors (ghazis) whose loyalty and morale could not always be trusted. The first Janissary units were formed from prisoners of war and slaves, probably as a result of the sultan taking his traditional one-fifth share of his army's booty in kind rather than cash. From the 1380s onwards, their ranks were filled under the devşirme system, where feudal dues were paid by service to the sultan. The "recruits" were mostly Christian youths, reminiscent of mamluks. China organized the Manchu people into the Eight Banner system in the early 17th century. Defected Ming armies formed the Green Standard Army. These troops enlisted voluntarily and for long terms of service. Late modern Conscription allowed the French Republic to form the Grande Armée, what Napoleon Bonaparte called "the nation in arms", which successfully battled European professional armies. Conscription, particularly when the conscripts are being sent to foreign wars that do not directly affect the security of the nation, has historically been highly politically contentious in democracies. In developed nations, the increasing emphasis on technological firepower and better-trained fighting forces, make mass conscription unlikely in the foreseeable future. Russia, as well as many other nations, retains mainly a conscript army. There is also a very rare citizen army as used in Switzerland (see Military of Switzerland). Field army A particular army can be named or numbered to distinguish it from military land forces in general. For example, the First United States Army and the Army of Northern Virginia. In the British Army it is normal to spell out the ordinal number of an army (e.g. First Army), whereas lower formations use figures (e.g. 1st Division). Armies (as well as army groups and theaters) are large formations which vary significantly between armed forces in size, composition, and scope of responsibility. In the Soviet Red Army and the Soviet Air Force, "Armies" could vary in size, but were subordinate to an Army Group-sized "front" in wartime. In peacetime, a Soviet army was usually subordinate to a military district. Viktor Suvorov's Inside the Soviet Army describes how Cold War era Soviet military districts were actually composed of a front headquarters and a military district headquarters co-located for administration and deception ('maskirovika') reasons. Formations In many countries, especially in Europe or North America, armies are often subdivided as follows: See also Army aviation List of armies List of armies by country List of numbered armies List of countries by number of military and paramilitary personnel Military history Military organization Militia Military Paramilitary Soldier References External links Types of military forces

Absalom ( ʾAḇšālōm, "father of peace"), according to the Hebrew Bible, was the third son of David, King of Israel with Maacah, daughter of Talmai, King of Geshur. 2 Samuel 14:25 describes him as the most handsome man in the kingdom. Absalom eventually rebelled against his father and was killed during the Battle of Ephraim's Wood. Biblical account Background Absalom, David's third son, by Maacah, was born in Hebron. At an early age, he moved, along with the transfer of the capital, to Jerusalem, where he spent most of his life. He was a great favorite of his father and of the people. His charming manners, personal beauty, insinuating ways, love of pomp, and royal pretensions captivated the hearts of the people from the beginning. He lived in great style, drove in a magnificent chariot, and had fifty men run before him. Little is known of Absalom's family life, but the biblical narrative states that he had three sons and one daughter, Tamar, who is described as a beautiful woman. From the language of 2 Samuel 18:18, Absalom states, "I have no son to keep my name in remembrance". It may be that his sons died before his statement of 2 Samuel 18:18. Or, as Matthew Henry suggests, Absalom's three sons may have been born after his statement. Aside from his daughter Tamar, Absalom had another daughter or granddaughter named Maacah, who later became the favorite wife of Rehoboam. Maacah was the mother of Abijah of Judah and the grandmother of Asa of Judah. She served as queen mother for Asa until he deposed her for idolatry. Murder of Amnon Absalom also had a sister named Tamar, who was raped by their half-brother Amnon, David's eldest son. After the rape, Absalom waited two years and then avenged Tamar by sending his servants to murder a drunken Amnon at a feast to which Absalom had invited all of King David's sons. After this murder Absalom fled to Talmai, who was the king of Geshur and Absalom's maternal grandfather. Not until three years later was Absalom fully reinstated in David's favour and did he finally return to Jerusalem. The revolt at Hebron While at Jerusalem, Absalom built support for himself by speaking to those who came to King David for justice, saying, "See, your claims are good and right; but there is no one deputed by the king to hear you", perhaps reflecting flaws in the judicial system of the united monarchy. "If only I were the judge of the land! Then all who had a suit or cause might come to me, and I would give them justice." He made gestures of flattery by kissing those who bowed before him instead of accepting supplication. He "stole the hearts of the people of Israel". After four years he declared himself king, raised a revolt at Hebron, the former capital, and slept with his father's concubines. All Israel and Judah flocked to him, and David, attended only by the Cherethites and Pelethites and his former bodyguard, which had followed him from Gath, found it expedient to flee. The priests Zadok and Abiathar remained in Jerusalem, and their sons Jonathan and Ahimaaz served as David's spies. Absalom reached the capital and consulted with the renowned Ahithophel (sometimes spelled Achitophel). (Although Absalom did avenge his sister's defilement ironically he himself showed himself not to be very much different from Amnon; as Amnon had sought the advice of Jonadab in order to rape Tamar, Absalom had sought the advice of Ahitophel who advised Absalom to have incestuous relations with his father's concubines in order to show all Israel how odious he was to his father [2 Samuel 16:20]. In regard to Ahitophel's motives: "..and great as was his wisdom, it was equalled by his scholarship. Therefore David did not hesitate to submit himself to his instruction, even though Ahithophel was a very young man, at the time of his death not more than thirty-three years old. The one thing lacking in him was sincere piety, and this it was that proved his undoing in the end, for it induced him to take part in Absalom's rebellion against David. Thus he forfeited even his share in the world to come. To this dire course of action he was misled by astrologic and other signs, which he interpreted as prophecies of his own kingship, when in reality they pointed to the royal destiny of his granddaughter Bath-sheba. Possessed by his erroneous belief, he cunningly urged Absalom to commit an unheard-of crime. Thus Absalom would profit nothing by his rebellion, for, though he accomplished his father's ruin, he would yet be held to account and condemned to death for his violation of family purity, and the way to the throne would be clear for Ahithophel, the great sage in Israel.") David took refuge from Absalom's forces beyond the Jordan River. However, he took the precaution of instructing a servant, Hushai, to infiltrate Absalom's court and subvert it. Once in place, Hushai convinced Absalom to ignore Ahithophel's advice to attack his father while he was on the run, and instead to prepare his forces for a major attack. This gave David critical time to prepare his own troops for the battle. When Ahithophel saw that his advice was not followed, he committed suicide by hanging himself. Battle of Ephraim's Wood A fateful battle was fought in the Wood of Ephraim (the name suggests a locality west of the Jordan) and Absalom's army was completely routed. When Absalom fled from David's army, his head was caught in the boughs of an oak tree as the mule he was riding ran beneath it. He was discovered there still alive by one of David's men, who reported this to Joab, the king's commander. Joab, accustomed to avenging himself, took this opportunity to even the score with Absalom. Absalom had once set Joab's field on fire and then made Amasa Captain of the Host instead of Joab. Killing Absalom was against David's explicit command, "Beware that none touch the young man Absalom". Joab injured Absalom with three darts through the heart and Absalom was subsequently killed by ten of Joab's armor-bearers. When David heard that Absalom was killed, although not how he was killed, he greatly sorrowed. David withdrew to the city of Mahanaim in mourning, until Joab roused him from "the extravagance of his grief" and called on him to fulfill his duty to his people. Memorial Absalom had erected a monument near Jerusalem to perpetuate his name: An ancient monument in the Kidron Valley near the Old City of Jerusalem, known as the Tomb of Absalom or Absalom's Pillar and traditionally identified as the monument of the biblical narrative, is now dated by modern archeologists to the first century AD. The Jewish Encyclopedia reports: "A tomb twenty feet high and twenty-four feet square, which late tradition points out as the resting-place of Absalom. It is situated in the eastern part of the valley of Kidron, to the east of Jerusalem. In all probability it is the tomb of Alexander Jannæus (Conder, in Hastings' Dict. Bible, article "Jerusalem", p. 597). It existed in the days of Josephus. However, archaeologists have now dated the tomb to the 1st century AD. In a 2013 conference, Professor Gabriel Barkay suggested that it could be the tomb of Herod Agrippa, the grandson of Herod the Great, based in part on the similarity to Herod's newly discovered tomb at Herodium. For centuries, it was the custom among passers-by—Jews, Christians and Muslims—to throw stones at the monument. Residents of Jerusalem would bring their unruly children to the site to teach them what became of a rebellious son. Rabbinic literature The life and death of Absalom offered to the rabbis a welcome theme wherewith to warn the people against false ambition, vainglory, and unfilial conduct. The vanity with which he displayed his beautiful hair, the rabbis say, became his snare and his stumbling-block. "By his long hair the Nazirite entangled the people to rebel against his father, and by it he himself became entangled, to fall a victim to his pursuers". And again, elsewhere: "By his vile stratagem he deceived and stole three hearts, that of his father, of the elders, and finally of the whole nation of Israel, and for this reason three darts were thrust into his heart to end his treacherous life". More striking is the following: "Did one ever hear of an oak-tree having a heart? And yet in the oak-tree in whose branches Absalom was caught, we read that upon its heart he was held up still alive while the darts were thrust through him. This is to show that when a man becomes so heartless as to make war against his own father, nature itself takes on a heart to avenge the deed." "The knowledge that a part of Absalom's following sided with him in secret,--that, though he was pursued by his son, his friends remained true to him,--somewhat consoled David in his distress. He thought that in these circumstances, if the worst came to the worst, Absalom would at least feel pity for him. At first, however, the despair of David knew no bounds. He was on the point of worshipping an idol, when his friend Hushai the Archite approached him, saying: "The people will wonder that such a king should serve idols." David replied: "Should a king such as I am be killed by his own son? It is better for me to serve idols than that God should be held responsible for my misfortune, and His Name thus be desecrated." Hushai reproached him: "Why didst thou marry a captive?" "There is no wrong in that," replied David, "it is permitted according to the law." Thereupon Hushai: "But thou didst disregard the connection between the passage permitting it and the one that follows almost immediately after it in the Scriptures, dealing with the disobedient and rebellious son, the natural issue of such a marriage." Absalom's end was beset with terrors. When he was caught in the branches of the oak-tree, he was about to sever his hair with a sword stroke, but suddenly he saw hell yawning beneath him, and he preferred to hang in the tree to throwing himself into the abyss alive. Absalom's crime was, indeed, of a nature to deserve the supreme torture, for which reason he is one of the few Jews who have no portion in the world to come. Popular legend states that the eye of Absalom was of immense size, signifying his insatiable greed. Indeed, "hell itself opened beneath him, and David, his father, cried seven times: 'My son! my son!' while bewailing his death, praying at the same time for his redemption from the seventh section of Gehenna, to which he was consigned". According to R. Meir, "he has no share in the life to come". And according to the description of Gehenna by Joshua ben Levi, who, like Dante, wandered through hell under the guidance of the angel Duma, Absalom still dwells there, having the rebellious heathen in charge; and when the angels with their fiery rods run also against Absalom to smite him like the rest, a heavenly voice says: "Spare Absalom, the son of David, My servant." "That the extreme penalties of hell were thus averted from him, was on account of David's eightfold repetition of his son's name in his lament over him. Besides, David's intercession had the effect of re-attaching Absalom's severed head to his body. At his death Absalom was childless, for all his children, his three sons and his daughter, died before him, as a punishment for his having set fire to a field of grain belonging to Joab." Art and literature Poetry Absalom and Achitophel (1681) is a landmark poetic political satire by John Dryden, using the Biblical story as a metaphor for the politics of the poet's own time. "Absalom" by Nathaniel Parker Willis (1806–1867) "Absaloms Abfall" by Rainer Maria Rilke ("The Fall of Absalom", trans. Stephen Cohn). "Absalom" is a section in Muriel Rukeyser's long poem The Book of the Dead (1938), inspired by the biblical text, spoken by a mother who lost three sons to silicosis. "Avshalom" by Yona Wallach, published in her first poetry collection Devarim (1966), alludes to the biblical character. Fiction In the 1946 short story "Absalom" by C.L. Moore and Henry Kuttner, the character Absalom is a child prodigy, who does non-consensual brain surgery on his father (a former child prodigy, though not as intelligent as his son) to make the father totally focused on Absalom's success. This relates to the Biblical story of the son usurping his father. Georg Christian Lehms, Des israelitischen Printzens Absolons und seiner Prinzcessin Schwester Thamar Staats- Lebens- und Helden-Geschichte (The Heroic Life and History of the Israelite Prince Absolom and his Princess Sister Tamar), novel in German published in Nuremberg, 1710. Absalom, Absalom! is a novel by William Faulkner, and refers to the return of the main character Thomas Sutpen's son. Oh Absalom! was the original title of Howard Spring's novel My Son, My Son!, later adapted for the film of the latter name. Cry, the Beloved Country by Alan Paton. Absalom was the name of Stephen Kumalo's son in the novel. Like the Biblical Absalom, Absalom Kumalo was at odds with his father, the two fighting a moral and ethical battle of sorts over the course of some of the novel's most important events. Absalom kills and murders a man, and also meets an untimely death. Throughout Robertson Davies's The Manticore a comparison is repeatedly made between the protagonist's problematic relations with his father and those of the Biblical Absalom and King David. Paradoxically, in the modern version, it is the rebellious son who has the first name "David". The book also introduces the term "Absalonism", as a generic term for a son's rebellion against his father. Absalom appears as a prominent character in Peter Shaffer's play Yonadab, which portrays Amnon's rape of Tamar and his murder at Absalom's hands. A scene in the Swedish writer Frans G. Bengtsson's historical novel "The Long Ships" depicts a 10th Century Christian missionary recounting the story of Absalom's rebellion to the assembled Danish court, including the aging King Harald Bluetooth and his son Sweyn Forkbeard; thereupon, King Harald exclaims "Some people can learn a lesson from this story!", casting a meaningful glance at his son Sweyn—whom the King (rightly) suspects of plotting a rebellion. In the novel The Book of Tamar by Nel Havas, the story of Absalom is presented from the viewpoint of his sister. While closely following the main events as related in the Bible, Havas concentrates on the motives behind Absalom's actions, which are more complex than depicted in the scriptures. In the novel Ender's Shadow by Orson Scott Card, the main character Bean invokes the quote to give solace to the kamikaze pilots Ender had unknowingly sent to their deaths to defeat the Formics. Music Josquin des Prez composed the motet "Absalon, fili mi" on the occasion of the death of Juan Borgia (Absalon being a further alternative spelling). Nicholas Gombert composed the two-part, eight-voice motet "Lugebat David Absalon". Heinrich Schütz (1585–1672) composed "Fili mi, Absalon" as part of his Sinfoniae Sacrae, op. 6. The single verse, 2 Samuel 18:33, regarding David's grief at the loss of his son ("And the king was much moved, and went up to the chamber over the gate, and wept: and as he went, thus he said, O my son Absalom, my son, my son Absalom! would God I had died for thee, O Absalom, my son, my son!"), is the inspiration for the text of several pieces of choral music, usually entitled When David Heard (such as those by Renaissance composers Thomas Tomkins and Thomas Weelkes, or modern composers Eric Whitacre, Joshua Shank, and Norman Dinerstein). This verse is also used in "David's Lamentation" by William Billings, first published in 1778. Leonard Cohen's poem "Prayer for Sunset" compares the setting sun to the raving Absalom, and asks whether another Joab will arrive tomorrow night to kill Absalom again. "Absalom, Absalom" is a song on the 1996 Compass CD Making Light of It by singer/songwriter Pierce Pettis, incorporating several elements of the biblical narrative. The Australian composer Nigel Butterley set the verse in his 2008 choral work "Beni Avshalom", commissioned by the Sydney Chamber Choir. During the finale of the song "Distant Early Warning" by Canadian band Rush, Geddy Lee sings, "Absalom, Absalom, Absalom"; lyrics written by drummer Neil Peart. David Olney's 2000 CD Omar's Blues includes the song "Absalom". The song depicts David grieving over the death of his son. The story of Absalom is referred to several places in folk singer Adam Arcuragi's song "Always Almost Crying". The San Francisco-based band Om mentions Absalom in their song "Kapila's Theme" from their debut album Variations on a Theme. The garage folk band David's Doldrums references Absalom in their song, "My Name Is Absalom". The song alludes to Absalom's feelings of solemnity and abandonment of love and hope. In "Every Kind Word" by Lackthereof, Danny Seim's project parallel to Menomena, Seim sings "... and your hair is long like Absalom." "Barach Hamelech", an Israeli song by Amos Etinger and Yosef Hadar. The grindcore band Discordance Axis references Absalom at the end of the track entitled "Castration Rite". In 2007 Ryland Angel released "Absalom" on Ryland Angel-Manhattan Records. "Hanging By His Hair" from the 1998 Wormwood album by The Residents recounts Absalom's defiance and death. Also performed on Roadworms (The Berlin Sessions) and Wormwood Live. "Absalom" is a song on Brand New Shadows's debut album, White Flags. It is a mournful lament from King David's perspective. "Absalom" is an album by the experimental/progressive band Stick Men featuring Tony Levin, Markus Reuter and Pat Mastelotto. The American Rock band Little Feat reference Absalom in their song "Gimme a Stone" on the album entitled Chinese Work Songs. This song is written from the perspective of King David—mainly focusing on the task of fighting Goliath—but contains a lament to Absalom. This was a cover of the song, the original being on the 1998 Americana concept album Largo, by David Forman and Levon Helm.

Agesilaus II (; ; c. 442 – 358 BC) was king of Sparta from c. 399 to 358 BC. Generally considered the most important king in the history of Sparta, Agesilaus was the main actor during the period of Spartan hegemony that followed the Peloponnesian War (431–404 BC). Although brave in combat, Agesilaus lacked the diplomatic skills to preserve Sparta's position, especially against the rising power of Thebes, which reduced Sparta to a secondary power after its victory at Leuctra in 371 BC. Despite the traditional secrecy fostered by the Spartiates, the reign of Agesilaus is particularly well-known thanks to the works of his friend Xenophon, who wrote a large history of Greece (the Hellenica) covering the years 411 to 362 BC, therefore extensively dealing with Agesilaus' rule. Xenophon furthermore composed a panegyric biography of his friend, perhaps to clean his memory from the criticisms voiced against him. Another historical tradition—much more hostile to Agesilaus than Xenophon's writings—has been preserved in the Hellenica Oxyrhynchia, and later continued by Diodorus of Sicily. Moreover, Plutarch wrote a biography of Agesilaus in his Parallel Lives, which contains many elements deliberately omitted by Xenophon. Early life Youth Agesilaus' father was King Archidamos II (r. 469–427), who belonged to the Eurypontid dynasty, one of the two royal families of Sparta. Archidamos already had a son from a first marriage with Lampito (his own step-aunt) named Agis. After the death of Lampito, Archidamos remarried in the early 440s with Eupolia, daughter of Melesippidas, whose name indicates an aristocratic status. Agesilaus was probably around 442, as he was said to have been aged 84 at his death in 358. Agesilaus also had a sister named Kyniska (the first woman in ancient history to achieve an Olympic victory). The name Agesilaus was rare and harks back to Agesilaus I, one of the earliest kings of Sparta. Agesilaus was born lame, a fact that should have cost him his life, since in Sparta deformed babies were thrown into a chasm. As he was not heir-apparent, he might have received some leniency from the tribal elders who examined male infants, or perhaps the first effects of the demographic decline of Sparta were already felt at the time, and only the most severely impaired babies were killed. At the age of 7, Agesilaus had to go through the rigorous education system of Sparta, called the agoge. Despite his disability, he brilliantly completed the training, which massively enhanced his prestige, especially after he became king. Indeed, as heirs-apparent were exempted of the agoge, very few Spartan kings had gone through the same training as the citizens; another notable exception was Leonidas, the embodiment of the "hero-king". Between 433 and 428, Agesilaus also became the younger lover of Lysander, an aristocrat from the circle of Archidamos, whose family had some influence in Libya. Spartan prince Little is known of Agesilaus' adult life before his reign, principally because Xenophon—his friend and main biographer—only wrote about his reign. Due to his special status, Agesilaus likely became a member of the Krypteia, an elite corps of young Spartans going undercover in Spartan territory to kill some helots deemed dangerous. Once he turned 20 and became a full citizen, Agesilaus was elected to a common mess, presumably that of his elder half-brother Agis II, who had become king in 427, of which Lysander was perhaps a member. Agesilaus probably served during the Peloponnesian War (431–428) against Athens, likely at the Battle of Mantinea in 418. Agesilaus married Kleora at some point between 408 and 400. Despite the influence she apparently had on her husband, she is mostly unknown. Her father was Aristomenidas, an influential noble with connections in Thebes. Thanks to three treaties signed with Persia in 412–411, Sparta received funding from the Persians, which it used to build a fleet that ultimately defeated Athens. This fleet was essentially led by Lysander, whose success gave him an enormous influence in the Greek cities of Asia as well as in Sparta, where he even schemed to become king. In 403 the two kings, Agis and Pausanias, acted together to relieve him from his command. Reign Accession to the throne (400–398 BC) Agis II died while returning from Delphi between 400 and 398. After his funeral, Agesilaus contested the claim of Leotychidas, the son of Agis II, using the widespread belief in Sparta that Leotychidas was an illegitimate son of Alcibiades—a famous Athenian statesman and nephew of Pericles, who had gone into exile in Sparta during the Peloponnesian War, and then seduced the queen. The rumours were strengthened by the fact that even Agis only recognised Leotychidas as his son on his deathbed. Diopeithes, a supporter of Leotychidas, however quoted an old oracle telling that a Spartan king could not be lame, thus refuting Agesilaus' claim, but Lysander cunningly returned the objection by saying that the oracle had to be understood figuratively. The lameness warned against by the oracle would therefore refer to the doubt on Leotychidas' paternity, and this reasoning won the argument. The role of Lysander in the accession of Agesilaus has been debated among historians, principally because Plutarch makes him the main instigator of the plot, while Xenophon downplays Lysander's influence. Lysander doubtless supported Agesilaus' accession because he hoped that the new king would in return help him to regain the importance that he lost in 403. Conspiracy of Cinadon (399 BC) The Conspiracy of Cinadon took place during the first year of Agesilaus' reign, in the summer of 399. Cinadon was a hypomeion, a Spartan who had lost his citizen status, presumably because he could not afford the price of the collective mess—one of the main reasons for the dwindling number of Spartan citizens in the Classical Era, called oliganthropia. It is probable that the vast influx of wealth coming to the city after its victory against Athens in 404 triggered inflation in Sparta, which impoverished many citizens with a fixed income, like Cinadon, and caused their downgrade. Therefore, the purpose of the plot was likely to restore the status of these disfranchised citizens. However, the plot was uncovered and Cinadon and its leaders executed—probably with the active participation of Agesilaus, but no further action was taken to solve the social crisis at the origin of the conspiracy. The failure of Agesilaus to acknowledge the critical problem suffered by Sparta at the time has been criticised by modern historians. Invasion of Asia Minor (396–394 BC) According to the treaties signed in 412 and 411 between Sparta and the Persian Empire, the latter became the overlord of the Greek city-states of Asia Minor. In 401, these cities and Sparta supported the bid of Cyrus the Younger (the Persian Emperor's younger son and a good friend of Lysander) against his elder brother, the new emperor Artaxerxes II, who nevertheless defeated Cyrus at Cunaxa. As a result, Sparta remained at war with Artaxerxes, and supported the Greek cities of Asia, which fought against Tissaphernes, the satrap of Lydia and Caria. In 397 Lysander engineered a large expedition in Asia headed by Agesilaus, likely to recover the influence he had over the Asian cities at the end of the Peloponnesian War. In order to win the approval of the Spartan assembly, Lysander built an army with only 30 Spartan citizens, so the risk would be limited; the bulk of the army consisted of 2,000 neodamodes (freed helots) and 6,000 Greek allies. In addition, Agesilaus obtained the support of the oracles of Zeus at Olympia and Apollo at Delphi. The sacrifice at Aulis (396 BC) Lysander and Agesilaus had intended the expedition to be a Panhellenic enterprise, but Athens, Corinth, and especially Thebes, refused to participate. In Spring 396, Agesilaus came to Aulis (in Boeotian territory) to sacrifice on the place where Agamemnon had done so just before his departure to Troy at the head of the Greek army in the Iliad, thus giving a grandiose aspect to the expedition. However he did not inform the Boeotians and brought his own seer to perform the sacrifice, instead of the local one. Learning this, the Boeotians prevented him from sacrificing and further humiliated him by casting away the victim; they perhaps intended to provoke a confrontation, as the relations between Sparta and Thebes had become execrable. Agesilaus then left to Asia, but Thebes remained hateful to him for the rest of his life. Campaign in Asia (396–394 BC) Once Agesilaus landed in Ephesus, the Spartan main base, he concluded a three months' truce with Tissaphernes, likely to settle the affairs among the Greek allies. He integrated some of the Greek mercenaries formerly hired by Cyrus the Younger (the Ten Thousand) in his army. They had returned from Persia under the leadership of Xenophon, who also remained in Agesilaus' staff. In Ephesus, Agesilaus' authority was nevertheless overshadowed by Lysander, who was reacquainted with many of his supporters, men he had placed in control of the Greek cities at the end of the Peloponnesian War. Angered by his local aura, Agesilaus humiliated Lysander several times to force him to leave the army, despite his former relationship and Lysander's role in his accession to the throne. Plutarch adds that after Agesilaus' emancipation from him, Lysander returned to his undercover scheme to make the monarchy elective. After Lysander's departure, Agesilaus raided Phrygia, the satrapy of Pharnabazus, until his advance guard was defeated not far from Daskyleion by the superior Persian cavalry. He then wintered at Ephesus, where he trained a cavalry force, perhaps on the advice of Xenophon, who had commanded the cavalry of the Ten Thousand. In 395, the Spartan king managed to trick Tissaphernes into thinking that he would attack Caria, in the south of Asia Minor, forcing the satrap to hold a defence line on the Meander river. Instead, Agesilaus moved north to the important city of Sardis. Tissaphernes hastened to meet the king there, but his cavalry sent in advance was defeated by Agesilaus' army. After his victory at the Battle of Sardis, Agesilaus became the first king to be given the command of both land and sea. He delegated the naval command to his brother-in-law Peisander, whom he appointed navarch despite his inexperience; perhaps Agesilaus wanted to avoid the rise of a new Lysander, who owed his prominence to his time as navarch. After his defeat, Tissaphernes was executed and replaced as satrap by Tithraustes, who gave Agesilaus 30 talents to move north to the satrapy of Pharnabazus (Persian satraps were often bitter rivals). Augesilaus' Phrygian campaign of 394 was fruitless, as he lacked the siege equipment required to take the fortresses of Leonton Kephalai, Gordion, and Miletou Teichos.Xenophon tells that Agesilaus then wanted to campaign further east in Asia and sow discontent among the subjects of the Achaemenid empire, or even to conquer Asia. Plutarch went further and wrote that Agesilaus had prepared an expedition to the heart of Persia, up to her capital of Susa, thus making him a forerunner of Alexander the Great. It is very unlikely that Agesilaus really had such a grand campaign in mind; regardless, he was soon forced to return to Europe in 394. Corinthian War (395–387 BC) Although Thebes and Corinth had been allies of Sparta throughout the Peloponnesian War, they were dissatisfied by the settlement of the war in 404, with Sparta as leader of the Greek world. Sparta's imperialist expansion in the Aegean greatly upset its former allies, notably by establishing friendly regimes and garrisons in smaller cities. Through large gifts, Tithraustes also encouraged Sparta's former allies to start a war in order to force the recall of Agesilaus from Asia—even though the influence of Persian gold has been exaggerated. The initiative came from Thebes, which provoked a war between their ally Ozolian Locris and Phocis in order to bring Sparta to the latter's defence. Lysander and the other king Pausanias entered Boeotia, which enabled the Thebans to bring Athens in the war. Lysander then besieged Haliartus without waiting for Pausanias and was killed in a Boeotian counter-attack. In Sparta, Pausanias was condemned to death by Lysander's friends and went into exile. After its success at Haliartus, Thebes was able to build a coalition against Sparta, with notably Argos and Corinth, where a war council was established, and securing the defection of most of the cities of northern and central Greece. Unable to wage war on two fronts and with the loss of Lysander and Pausanias, Sparta had no choice but to recall Agesilaus from Asia. The Asian Greeks fighting for him said they wanted to continue serving with him, while Agesilaus promised he would return to Asia as soon as he could. Agesilaus returned to Greece by land, crossing the Hellespont and from there along the coast of the Aegean Sea. In Thessaly he won a cavalry battle near Narthacium against the Pharsalians who had made an alliance with Thebes. He then entered Boeotia by the Thermopylae, where he received reinforcements from Sparta. Meanwhile, Aristodamos—the regent of the young Agiad king Agesipolis—won a large victory at Nemea near Argos, which was offset by the disaster of the Spartan navy at Knidos against the Persian fleet led by Konon, an exiled Athenian general. Agesilaus lied to his men about the outcome of the battle of Knidos to avoid demoralising them as they were about to fight a large engagement against the combined armies of Thebes, Athens, Argos and Corinth. The following Battle of Coroneia was a classic clash between two lines of hoplites. The anti-Spartan allies were rapidly defeated, but the Thebans managed to retreat in good order, despite Agesilaus' activity on the frontline, which caused him several injuries. The next day the Thebans requested a truce to recover their dead, therefore conceding defeat, although they had not been bested on the battlefield. Agesilaus appears to have tried to win an honourable victory, by risking his life and being merciful with some Thebans who had sought shelter in the nearby Temple of Athena Itonia. He then moved to Delphi, where he offered one tenth of the booty he had amassed since his landing at Ephesos, and returned to Sparta. No pitched battle took place in Greece in 393. Perhaps Agesilaus was still recovering from his wounds, or he was deprived of command because of the opposition of Lysander's and Pausanias' friends, who were disappointed by his lack of decisive victory and his appointment of Peisander as navarch before the disaster of Knidos. The loss of the Spartan fleet besides allowed Konon to capture the island of Kythera, in the south of the Peloponnese, from where he could raid Spartan territory. In 392, Sparta sent Antalcidas to Asia in order to negotiate a general peace with Tiribazus, the satrap of Lydia, while Sparta would recognise Persia's sovereignty over the Asian Greek cities. However, the Greek allies also sent emissaries to Sardis to refuse Antalicidas' plan, and Artaxerxes likewise rejected it. A second peace conference in Sparta failed the following year because of Athens. A personal enemy of Antalicidas, Agesilaus likely disapproved these talks, which show that his influence at home had waned. Plutarch says that he befriended the young Agiad king Agesipolis, possibly to prevent his opponents from coalescing behind him. By 391 Agesilaus had apparently recovered his influence as he was appointed at the head of the army, while his half-brother Teleutias became navarch. The target was Argos, which had absorbed Corinth into a political union the previous year. In 390 BC he made several successful expeditions into Corinthian territory, capturing Lechaeum and Piraeus. The loss, however, of a battalion (mora), destroyed by Iphicrates, neutralized these successes, and Agesilaus returned to Sparta. In 389 BC he conducted a campaign in Acarnania, but two years later the Peace of Antalcidas, warmly supported by Agesilaus, put an end to the war, maintaining Spartan hegemony over Greece and returning the Greek cities of Asia Minor to the Achaemenid Empire. In this interval, Agesilaus declined command over Sparta's aggression on Mantineia, and justified Phoebidas' seizure of the Theban Cadmea so long as the outcome provided glory to Sparta. Decline When war broke out afresh with Thebes, Agesilaus twice invaded Boeotia (in 378 and 377 BC), although he spent the next five years largely out of action due to an unspecified but apparently grave illness. In the congress of 371 an altercation is recorded between him and the Theban general Epaminondas, and due to his influence, Thebes was peremptorily excluded from the peace, and orders given for Agesilaus's royal colleague Cleombrotus to march against Thebes in 371. Cleombrotus was defeated and killed at the Battle of Leuctra and the Spartan supremacy overthrown. In 370 Agesilaus was engaged in an embassy to Mantineia, and reassured the Spartans with an invasion of Arcadia. He preserved an un-walled Sparta against the revolts and conspiracies of helots, perioeci and even other Spartans; and against external enemies, with four different armies led by Epaminondas penetrating Laconia that same year. Asia Minor expedition (366 BC) In 366 BC, Sparta and Athens, dissatisfied with the Persian king's support of Thebes following the embassy of Philiscus of Abydos, decided to provide careful military support to the opponents of the Achaemenid king. Athens and Sparta provided support for the revolting satraps in the Revolt of the Satraps, in particular Ariobarzanes: Sparta sent a force to Ariobarzanes under an aging Agesilaus, while Athens sent a force under Timotheus, which was however diverted when it became obvious that Ariobarzanes had entered frontal conflict with the Achaemenid king. An Athenian mercenary force under Chabrias was also sent to the Egyptian Pharao Tachos, who was also fighting against the Achaemenid king. According to Xenophon, Agesilaus, in order to gain money for prosecuting the war, supported the satrap Ariobarzanes of Phrygia in his revolt against Artaxerxes II in 364 (Revolt of the Satraps). Again, in 362, Epaminondas almost succeeded in seizing the city of Sparta with a rapid and unexpected march. The Battle of Mantinea, in which Agesilaus took no part, was followed by a general peace: Sparta, however, stood aloof, hoping even yet to recover her supremacy. Expedition to Egypt Sometime after the Battle of Mantineia, Agesilaus went to Egypt at the head of a mercenary force to aid the king Nectanebo I and his regent Teos against Persia. In the summer of 358, he transferred his services to Teos's cousin and rival, Nectanebo II, who, in return for his help, gave him a sum of over 200 talents. On his way home Agesilaus died in Cyrenaica, around the age of 84, after a reign of some 41 years. His body was embalmed in wax, and buried at Sparta. He was succeeded by his son Archidamus III. Legacy Agesilaus was of small stature and unimpressive appearance, and was lame from birth. These facts were used as an argument against his succession, an oracle having warned Sparta against a "lame reign." Most ancient writers considered him a highly successful leader in guerrilla warfare, alert and quick, yet cautious—a man, moreover, whose personal bravery was rarely questioned in his own time. Of his courage, temperance, and hardiness, many instances are cited, and to these were added the less Spartan qualities of kindliness and tenderness as a father and a friend. As examples, there is the story of his riding a stick-horse with his children and upon being discovered by a friend desiring that he not mention till he himself were the father of children; and because of the affection of his son Archidamus' for Cleonymus, he saved Sphodrias, Cleonymus' father, from execution for his incursion into the Piraeus, and dishonorable retreat, in 378. Modern writers tend to be slightly more critical of Agesilaus' reputation and achievements, reckoning him an excellent soldier, but one who had a poor understanding of sea power and siegecraft. As a statesman he won himself both enthusiastic adherents and bitter enemies. Agesilaus was most successful in the opening and closing periods of his reign: commencing but then surrendering a glorious career in Asia; and in extreme age, maintaining his prostrate country. Other writers acknowledge his extremely high popularity at home, but suggest his occasionally rigid and arguably irrational political loyalties and convictions contributed greatly to Spartan decline, notably his unremitting hatred of Thebes, which led to Sparta's humiliation at the Battle of Leuctra and thus the end of Spartan hegemony. Historian J. B. Bury remarks that "there is something melancholy about his career:" born into a Sparta that was the unquestioned continental power of Hellas, the Sparta which mourned him eighty four years later had suffered a series of military defeats which would have been unthinkable to his forebears, had seen its population severely decline, and had run so short of money that its soldiers were increasingly sent on campaigns fought more for money than for defense or glory. Other historical accounts paint Agesilaus as a prototype for the ideal leader. His awareness, thoughtfulness, and wisdom were all traits to be emulated diplomatically, while his bravery and shrewdness in battle epitomized the heroic Greek commander. These historians point towards the unstable oligarchies established by Lysander in the former Athenian Empire and the failures of Spartan leaders (such as Pausanias and Kleombrotos) for the eventual suppression of Spartan power. The ancient historian Xenophon was a huge admirer and served under Agesilaus during the campaigns into Asia Minor. Plutarch includes among Agesilaus' 78 essays and speeches comprising the apophthegmata Agesilaus' letter to the ephors on his recall: And when asked whether Agesilaus wanted a memorial erected in his honor: Agesilaus lived in the most frugal style alike at home and in the field, and though his campaigns were undertaken largely to secure booty, he was content to enrich the state and his friends and to return as poor as he had set forth. Selected quotes When someone was praising an orator for his ability to magnify small points, Agesilaus said, "In my opinion it's not a good cobbler who fits large shoes on small feet." Another time Agesilaus watched a mouse being pulled from its hole by a small boy. When the mouse turned around, bit the hand of its captor and escaped, he pointed this out to those present and said, "When the tiniest creature defends itself like this against aggressors, what ought men to do, do you reckon?" Certainly when somebody asked what gain the laws of Lycurgus had brought Sparta, Agesilaus answered, "Contempt for pleasures." Asked once how far Sparta's boundaries stretched, Agesilaus brandished his spear and said, "As far as this can reach." On noticing a house in Asia roofed with square beams, Agesilaus asked the owner whether timber grew square in that area. When told no, it grew round, he said, "What then? If it were square, would you make it round?" Invited to hear an actor who could perfectly imitate the nightingale, Agesilaus declined, saying he had heard the nightingale itself.

Alexander () was Tyrant or Despot of Pherae in Thessaly, ruling from 369 to c. 356 BC. Following the assassination of Jason, the tyrant of Pherae and Tagus of Thessaly, in 370 BC, his brother Polydorus ruled for a year, but he was then poisoned by another brother (or nephew, according to Xenephon), Alexander. Alexander governed tyrannically and was constantly seeking to control Thessaly and the kingdom of Macedonia. He also engaged in piratical raids on Attica. Alexander was murdered by the brothers of his wife, Thebe, as it was said that she lived in fear of her husband and hated Alexander's cruel and brutal character. Reign The accounts of how Alexander came to power vary somewhat in minor points. Diodorus Siculus tells us that upon the assassination of the tyrant Jason of Pherae, in 370 BC, his brother Polydorus ruled for a year, but he was then poisoned by Alexander, another brother. However, according to Xenophon, Polydorus was murdered by his brother Polyphron, who was, in turn, murdered by his nephew Alexander —son of Jason, in 369 BC. Plutarch relates that Alexander worshipped the spear he slew his uncle with as if it were a god. Alexander governed tyrannically, and according to Diodorus, differently from the former rulers, but Polyphron, at least, seems to have set him the example. The states of Thessaly, which had previously acknowledged the authority of Jason of Pherae, were not so willing to submit to Alexander the tyrant, (especially the old family of the Aleuadae of Larissa, who had most reason to fear him). Therefore, they applied for help from Alexander II of Macedon. Alexander prepared to meet his enemy in Macedonia, but the king anticipated him, and, reaching Larissa, was admitted into the city. Alexander withdrew to Pherae whilst the Macedonian King placed a garrison in Larissa, as well as in Crannon, which had also come over to him. But once the bulk of the Macedonian army had retired, the states of Thessaly feared the return and vengeance of Alexander, and so sent for aid to Thebes, whose policy it was to put a check on any neighbour who might otherwise become too formidable. Thebes accordingly dispatched Pelopidas to the aid of Thessaly. On arrival of Pelopidas at Larissa, whence according to Diodorus, he dislodged the Macedonian garrison, Alexander presented himself and offered submission. When Pelopidas expressed indignation at the tales of Alexander's profligacy and cruelty, Alexander took alarm and fled. These events appear to refer to the early part of 368 BC. In the summer of that year Pelopidas was again sent into Thessaly, in consequence of fresh complaints against Alexander. Accompanied by Ismenias, he went merely as a negotiator, without any military force, and was seized by Alexander and thrown into prison. The scholar William Mitford suggested that Pelopidas was taken prisoner in battle, but the language of Demosthenes hardly supports such an inference. The Thebans sent a large army into Thessaly to rescue Pelopidas, but they could not keep the field against the superior cavalry of Alexander, who, aided by auxiliaries from Athens, pursued them with great slaughter. The destruction of the whole Theban army is said to only have been averted by the ability of Epaminondas, who was serving in the campaign, but not as general. In 367 BC, Alexander carried out a massacre of the citizens of Scotussa. A fresh Theban expedition into Thessaly, under Epaminondas resulted, according to Plutarch, in a three-year truce and the release of prisoners, including Pelopidas. During the next three years, Alexander seemed to renew his attempts to subdue the states of Thessaly, especially Magnesia and Phthiotis, for upon the expiry of the truce, in 364 BC, they again applied to Thebes for protection from him. The Theban army under Pelopidas is said to have been dismayed by an eclipse on 13 July 364 BC, and Pelopidas, leaving the bulk of his army behind, entered Thessaly at the head of three hundred volunteer horsemen and some mercenaries. At Cynoscephalae, the Thebans defeated Alexander, but Pelopidas was killed. This was closely followed by another Theban victory under Malcites and Diogiton. Alexander was then forced to restore the conquered towns to the Thessalians, confine himself to Pherae, join the Boeotian League, and become a dependent ally of Thebes. If the death of Epaminondas in 362 freed Athens from fear of Thebes, it appears at the same time to have exposed it to further aggression from Alexander, who made a piratical raid on Tinos and other cities of the Cyclades, plundering them, and making slaves of the inhabitants. He also besieged Peparethus, and "even landed troops in Attica itself, and seized the port of Panormus, a little eastward of Sounion." The Athenian admiral Leosthenes defeated Alexander and managed to relieve Peparethus, but Alexander escaped from being blockaded in Panormus, took several Attic triremes, and plundered the Piraeus. Death The murder of Alexander is assigned by Diodorus to 357/356. Plutarch gives a detailed account of it, with a lively picture of the palace. Guards watched throughout the night, except at Alexander's bedchamber, which was at the top of a ladder with a ferocious chained dog guarding the door. Thebe, Alexander's wife and cousin (or half-sister, as the daughter of Jason of Pherae), concealed her three brothers in the house during the day, had the dog removed when Alexander had gone to rest, and, having covered the steps of the ladder with wool, brought up the young men to her husband's chamber. Though she had taken away Alexander's sword, they feared to set about the deed until she threatened to wake him. Her brothers then entered and killed Alexander. His body was cast into the streets, and exposed to every indignity. Of Thebe's motive for the murder different accounts are given. Plutarch states it to have been fear of her husband, together with hatred of Alexander's cruel and brutal character, and ascribes these feelings principally to the representations of Pelopidas, when she visited him in his prison. In Cicero the deed is ascribed to jealousy. Other accounts have it that Alexander had taken Thebe's youngest brother as his eromenos and tied him up. Exasperated by his wife's pleas to release the youth, he murdered the boy, which drove her to revenge.<ref>Aristot. ap. Cicero de Div. i. 25; the dream of Eudemus</ref> Other It is written in Plutarch's Second Oration On the Fortune or the Virtue of Alexander the Great (see Moralia''), and in Claudius Aelianus' Varia Historia that Alexander left a tragedy in a theatre because he did not wish to weep at fiction when unmoved by his own cruelty. This suggests that while Alexander was a tyrant, perhaps his iron heart could be softened. The actor was threatened with punishment because Alexander was so moved while watching.

Alfonso XII (Alfonso Francisco de Asís Fernando Pío Juan María de la Concepción Gregorio Pelayo; 28 November 185725 November 1885), also known as El Pacificador or the Peacemaker, was King of Spain from 29 December 1874 to his death in 1885. After a revolution that deposed his mother Isabella II from the throne in 1868, Alfonso studied in Austria and France. His mother abdicated in his favour in 1870, and he returned to Spain as king in 1874 following a military coup against the First Republic. Alfonso died aged 27 in 1885, and was succeeded by his son, Alfonso XIII, who was born the following year. He is the most recent monarch of Spain to have died while on the throne. Political background, early life and paternity Alfonso was born in Madrid on 28 November 1857, the eldest son of Queen Isabella II and King Francisco de Asís. There had been speculation that Alfonso's biological father may have been someone else. But, these false rumors were used as political propaganda against Alfonso by the Carlists to legitimate their power. His mother's accession created the second cause of instability, the Carlist Wars. The supporters of the Count of Molina as king of Spain rose to have him enthroned. In addition, within the context of the post-Napoleonic restorations and revolutions which engulfed the West both in Europe and the Americas, both the Carlistas and the Isabelino conservatives were opposed to the new Napoleonic constitutional system. Much like in Britain, which subtracted itself from the liberal constitutional process, Spanish conservatives wanted to continue with the Traditional Spanish Organic Laws such as the Fuero Juzgo, the Novísima Recopilación and the Partidas of Alfonso X. This led to the third cause of instability of note, the "Independence of the American Kingdoms", recognized between 1823 and 1850. A split nation When Queen Isabella II and her husband were forced to leave Spain by the Revolution of 1868, Alfonso accompanied them to Paris. From there, he was sent to the Theresianum in Vienna to continue his studies. On 25 June 1870, he was recalled to Paris, where his mother abdicated in his favour, in the presence of a number of Spanish nobles who had tied their fortunes to those of the exiled queen. He assumed the name Alfonso XII, for although no king of united Spain had borne the name "Alfonso XI", the Spanish monarchy was regarded as continuous with the more ancient monarchy represented by the 11 kings of Asturias, León and Castile also named Alfonso. The Republic After the revolution, the Cortes decided to set up a new dynasty on the throne. Prince Amadeo of Savoy, the younger son of King Victor Emmanuel II of Italy and a distant cousin of Alfonso by common descent from Charles III, was recognized as King of Spain in November 1870. During a tumultuous reign, Amadeo was targeted by assassination attempts and struggled with opposition from both Carlists and republicans while his own faction split. After the Carlists revolted and the Third Carlist War broke out, he abdicated and returned to Italy in early 1873. Following Amadeo's abandonment, the First Spanish Republic was established, including the territories of Cuba, Puerto Rico and the Pacific Archipelagos. The first act of President Estanislao Figueras was to extend the abolition of slavery to Puerto Rico; Cuban slaves would have to wait until 1889. The republicans were not in agreement either, and they had to contend with a war in Cuba and Muslim uprisings in Spanish Morocco. In the midst of these crises, the Carlist War continued and the Carlist party made itself strong in areas with claims over their national and institutional specificity such as Catalonia and the Basque Country. This unrest led to the creation of a group in favour of the Bourbon Restoration, led by the moderate conservative Antonio Cánovas del Castillo. Alfonso was well-educated and cultured, especially compared to his mother. His tutors took great care to have him educated in good schools and to familiarize him with different cultures, languages and government models throughout Europe. During the Franco-Prussian War, Alfonso relocated from Paris to Geneva with his family, and then continued his studies at the Theresianum in Vienna in 1872. Cánovas began to take responsibility for Alfonso's education with the goal of shaping him into the ideal king for the planned Bourbon Restoration, and next sent him to the Royal Military College, Sandhurst, in England. The training he received there was severe but more cosmopolitan than it would have been in Spain, given its atmosphere at the time. On 1 December 1874, Alfonso issued the Sandhurst Manifesto, where he set the ideological basis of the Bourbon Restoration. It was drafted in reply to a birthday greeting from his followers, a manifesto proclaiming himself the sole representative of the Spanish monarchy. At the end of 1874, Brigadier Martínez Campos, who had long been working more or less openly for the king, led some battalions of the central army to Sagunto, rallied the troops sent against him to his own flag, and entered Valencia in the king's name. Thereupon the President resigned, and his power was transferred to the king's plenipotentiary and adviser, Cánovas. The 29 December 1874 military coup of Gen. Martinez Campos in Sagunto ended the failed republic and meant the rise of the young Prince Alfonso. Return from exile Within a few days after Canovas del Castillo took power as Premier, the new king, proclaimed on 29 December 1874, arrived at Madrid, passing through Barcelona and Valencia and was acclaimed everywhere (1875). In 1876, a vigorous campaign against the Carlists, in which the young king took part, resulted in the defeat of Don Carlos and the Duke's abandonment of the struggle. Initially led by Canovas del Castillo as moderate prime minister, what was thought at one time as a coup aimed at placing the military in the political-administrative positions of power, in reality ushered in a civilian regime that lasted until Primo de Rivera's 1923 coup d'état. Cánovas was the real architect of the new regime of the Restoration. In order to eliminate one of the problems of the reign of Isabel II, the single party and its destabilizing consequences, the Liberal Party was allowed to incorporate and participate in national politics, and the 'turnismo' or alternation was to become the new system. Turnismo would be endorsed in the Constitution of 1876 and the Pact of Pardo Palace (1885). It meant that liberal and conservative prime ministers would succeed each other ending thus the troubles. This led to the end of the Carlist revolts and the victory over the New York-backed Cuban revolutionaries, and led to a huge backing both by insular and peninsular Spaniards of Alfonso. His government continued the operations of the Ministry for Overseas Affairs which began under his mother's reign. The ministry was responsible for the theft of indigenous human remains and artifacts throughout colonized lands from 1863 to 1899. To this day, the majority of the stolen bodies of indigenous peoples, some still displayed in Spanish museums, have yet to be returned to their ancestral lands. Alfonso's short reign established the foundations for the final socioeconomic recuperation of Spain after the 1808–1874 crisis. Both European (the coastal regions, such as the Basque Country, Catalonia, and Asturias) and Overseas – Antilles and Pacific were able to grow steadily. Cuba and Puerto Rico prospered to the point that Spain's first train was between Havana and Camagüey, and the first telegraph in Latin America was in Puerto Rico, established by Samuel Morse, whose daughter lived there with her husband. Upon the American invasion of Puerto Rico, ten US dollars were needed to buy one Puerto Rican peso. First marriage On 23 January 1878 at the Basilica of Atocha in Madrid, Alfonso married his first cousin, Princess Maria de las Mercedes, but she died within six months of the marriage. Second marriage and rule On 29 November 1879 at the Basilica of Atocha in Madrid, Alfonso married his double third cousin, Archduchess Maria Christina of Austria. During the honeymoon, a pastry cook named Otero fired at the young sovereign and his wife as they were driving in Madrid. The children of this marriage were: María de las Mercedes, Princess of Asturias, (11 September 188017 October 1904), married on 14 February 1901 to Prince Carlos of Bourbon-Two Sicilies, and titular heir from the death of her father until the posthumous birth of her brother María Teresa, (12 November 188223 September 1912), married to Prince Ferdinand of Bavaria on 12 January 1906 Alfonso XIII (17 May 188628 February 1941). Born posthumously. He married Princess Victoria Eugenie of Battenberg Alfonso had two sons by Elena Armanda Nicolasa Sanz y Martínez de Arizala (15 December 1849, in Castellón de la Plana – 24 December 1898, in Paris): Alfonso Sanz y Martínez de Arizala (28 January 1880, in Madrid19 March 1970, in Paris), married in 1922 to María de Guadalupe de Limantour y Mariscal Fernando Sanz y Martínez de Arizala (28 February 1881, in Madrid8 January 1925, in Pau, France), unmarried and without issue In 1881 Alfonso refused to sanction a law by which the ministers were to remain in office for a fixed term of 18 months. Upon the consequent resignation of Canovas del Castillo, he summoned Práxedes Mateo Sagasta, the Liberal leader, to form a new cabinet. Death and impact In November 1885, Alfonso died, just short of his 28th birthday, at the Royal Palace of El Pardo near Madrid. He had been suffering from tuberculosis, but the immediate cause of his death was a recurrence of dysentery. In 1902, his widow Maria Cristina initiated a national contest to build a monument in memory of Alfonso. The winning design, by José Grases Riera, was erected in an artificial lake in Madrid's Parque del Buen Retiro in 1922. Coming to the throne at such an early age Alfonso had served no apprenticeship in the art of ruling. Benevolent and sympathetic in disposition, he won the affection of his people by fearlessly visiting districts ravaged by cholera or devastated by earthquake in 1885. His capacity for dealing with men was considerable, and he never allowed himself to become the instrument of any particular party. During his short reign, peace was established both at home and abroad, finances were well regulated, and the various administrative services were placed on a basis that afterwards enabled Spain to pass through the disastrous war with the United States without the threat of a revolution.

Ambrosius Aurelianus (; Anglicised as Ambrose Aurelian and called Aurelius Ambrosius in the Historia Regum Britanniae and elsewhere) was a war leader of the Romano-British who won an important battle against the Anglo-Saxons in the 5th century, according to Gildas. He also appeared independently in the legends of the Britons, beginning with the 9th-century Historia Brittonum. Eventually he was transformed by Geoffrey of Monmouth into the uncle of King Arthur, the brother of Arthur's father Uther Pendragon, as a ruler who precedes and predeceases them both. He also appears as a young prophet who meets the tyrant Vortigern; in this guise, he was later transformed into the wizard Merlin. According to Gildas Ambrosius Aurelianus is one of the few people whom Gildas identifies by name in his sermon De Excidio et Conquestu Britanniae, and the only one named from the 5th century. De Excidio is considered the oldest extant British document about the so-called Arthurian period of Sub-Roman Britain. Following the destructive assault of the Saxons, the survivors gather together under the leadership of Ambrosius, who is described as: Some basic information on Ambrosius can be deduced from the brief passage: Ambrosius was possibly of high birth and very likely a Christian (Gildas says that he won his battles "with God's help"). Ambrosius's parents were slain by the Saxons and he was among the few survivors of their initial invasion. According to Gildas, Ambrosius organised the survivors into an armed force and achieved the first military victory over the Saxon invaders. However, this victory was not decisive: "Sometimes the Saxons and sometimes the citizens [meaning the Romano-British inhabitants] were victorious." Due to Gildas's description of him, Ambrosius is one of the figures called the Last of the Romans. Scholarship questions Two points in Gildas's description have attracted much scholarly commentary. The first is what Gildas meant by saying Ambrosius' family "had worn the purple". Roman emperors and male Patricians wore clothes with a purple band to denote their class so the reference to purple may be to an aristocratic heritage. Roman military tribunes (tribuni militum), senior officers in Roman legions, wore a similar purple band so the reference may be to a family background of military leadership. The tradition was old, as the togas and pallia of already ancient senators and tribunes were trimmed with the purple band. In the church, "the purple" is a euphemism for blood and therefore "wearing the purple" may be a reference to martyrdom or a bishop's robe. In addition, in the later Roman Empire both Roman consuls and governors of consular rank also wore clothes with a purple fringe. The Notitia Dignitatum, a Roman catalogue of official posts, lists four or five provincial governors in Roman Britain and two of them were of consular rank. One was the governor of Maxima Caesariensis and the other that of Valentia. The parent who wore the purple may well have been one of these governors, whose names were not recorded. It has been suggested by historian Alex Woolf that Ambrosius may have been related to the 5th-century Romano-British usurpers Marcus or Gratian – Woolf expresses a preference based on nomenclature for Marcus. Frank D. Reno, an Arthurian scholar, has instead argued that the name "Aurelianus" indicates the descent of Ambrosius from the Illyrian Roman emperor Aurelian (reigned 270–275). Aurelian's military campaigns included the conquest of the Gallic Empire. N. J. Higham suggests that Ambrosius may have been distantly related to imperial families of the late Roman Empire, such as the Theodosian dynasty. Branches of this particular dynasty were known to be active in western Roman provinces like Hispania. Mike Ashley instead focuses on the name "Ambrosius" and its possible connection to Saint Ambrosius, a fourth-century Bishop of Milan, who also served as consular governor in areas of Roman Italy. The father of the Bishop is sometimes claimed to be a fourth century Praetorian prefect of Gaul named Aurelius Ambrosius, whose areas included Britain, though some modern scholars doubt that Saint Ambrosius was related to this man (instead identifying his father with an official named Uranius mentioned in an extract from the Theodosian Code). Ashley suggests that Ambrosius Aurelianus was related to the two Aurelii Ambrosii. Tim Venning points out that the name "Aurelianus" could be the result of a Roman adoption. When a boy was adopted into a new gens (clan), he received the family names of his new family but was often additionally called by a cognomen indicating his descent from his original family. The additional cognomen often had the form "-anus". When Gaius Octavius from gens Octavia was adopted by his uncle Gaius Julius Caesar, he was often distinguished from his adoptive father by the addition "Octavianus". In this case, Ambrosius may have been a member of gens Aurelia who was adopted by another gens/family. The second question is the meaning of the word avita: Gildas could have meant "ancestors", or intended it to mean more specifically "grandfather" – thus indicating Ambrosius lived about a generation before the Battle of Badon. Lack of information prevents sure answers to these questions. Gildas's motives N. J. Higham wrote a book on Gildas and the literary tropes that he used. He has suggested that Gildas may have had considerable motive for drawing attention to Ambrosius. He was not attempting to write a historical biography of the man, according to Higham, but setting him as an example to his contemporaries. It was essential to the philosophy of Gildas that Briton leaders who achieved victory over the barbarians were only able to do so because of divine aid. And only those who had superior Christian virtues were deserving of this aid. Ambrosius Aurelianus was apparently known for at least one such victory over the barbarians. To fit him into his worldview, Gildas was almost required to feature the former warrior as a man of exceptional virtues and obedience to God. He was made to fit Gildas's version of a model leader. Higham also suggests that the Roman lineage of Ambrosius was highlighted for a reason. Gildas was apparently intentionally connecting him with the legitimate authority and military virtues of the Romans. He was also contrasting him with the subsequent Briton rulers whose reigns lacked in such legitimacy. Identifying historical figures Gildas is a primary source for the Battle of Badon, yet he never mentions the names of the combatants. Therefore, we cannot know if Ambrosius Aurelianus or his successors took part in the battle. The names of the Saxon leaders in the battle are also not recorded. The identities of Ambrosius's descendants are unknown, since Gildas never identifies them by name. It is safe to assume that they were Gildas's contemporaries and known to the author. Higham suggests that they were prominent figures of the time. Their lineage and identities were probably sufficiently familiar to his intended audience that they did not have to be named. The work portrays Ambrosius's descendants as inferior to their ancestor as part of his criticism on rulers of his time, according to Higham. Those criticised were likely aware that the vitriol was intended for them, but probably would not challenge a work offering such a glowing report of their illustrious ancestor. Mike Ashley suggests that the descendants of Ambrosius could include other people named by Gildas. He favours the inclusion in this category of one Aurelius Caninus ("Aurelius the dog-like"), whom Gildas accuses of parricide, fornication, adultery, and warmongering. His name "Aurelius" suggests Romano-British descent. The insulting nickname "Caninus" was probably invented by Gildas himself, who similarly insults other contemporary rulers. Due to the name used by Gildas, there are theories that this ruler was actually named Conan/Cynan/Kenan. Some identify him with Cynan Garwyn, a 6th-century King of Powys, though it is uncertain if he was a contemporary of Gildas or lived one or two generations following him. Another theory is that this ruler did not reign in Britain but in Brittany. Caninus, in this view, might be Conomor ("Great Dog"). Conomor is considered a likelier contemporary of Gildas. Conomor was likely from Domnonée, an area of Brittany controlled by British immigrants from Dumnonia. He might be remembered in British legend as Mark of Cornwall. Gildas primarily features the Saxons as barbarian raiders; their invasions involved a slow and difficult process of military conquest. By AD 500, possibly the time described by Gildas, Anglo-Saxons controlled the Isle of Wight, Kent, Lincolnshire, Norfolk, Suffolk, and coastal areas of Northumberland and Yorkshire. The rest of the former Roman Britain was still under the control of the local Britons or remnants of the Roman provincial administration. Gildas also mentions depopulation of cities and this probably reflects historical facts. Londinium, once a major city, was completely abandoned during the 5th century. According to Bede Bede follows Gildas's account of Ambrosius in his Ecclesiastical History of the English People, but in his Chronica Majora he dates Ambrosius's victory to the reign of the Emperor Zeno (474–491). Bede's treatment of the 5th century history of Great Britain is not particularly valuable as a source. Until about the year 418, Bede could choose between several historical sources and often followed the writings of Orosius. Following the end of Orosius's history, Bede apparently lacked other available sources and relied extensively on Gildas. Entries from this period tend to be close paraphrases of Gildas's account with mostly stylistic changes. Bede's account of Ambrosius Aurelianus has been translated as following: Bede does not mention the descendants of Ambrosius Aurelianus, nor their supposed degeneracy. According to Nennius The Historia Brittonum, attributed to Nennius, preserves several snippets of lore about Ambrosius. Despite the traditional attribution, the authorship of the work and the period of its writing are open questions for modern historians. There are several extant manuscript versions of the work, varying in details. The most important ones have been dated to between the 9th and the 11th century. Some modern scholars think it unlikely that the work was composed by a single writer or compiler, suggesting that it may have taken centuries to reach its final form, though this theory is not conclusive. In Chapter 31, we are told that Vortigern ruled in fear of Ambrosius. This is the first mention of Ambrosius in the work. According to Frank D. Reno, this would indicate that Ambrosius's influence was formidable, since Vortigern considered him more of a threat than northern invaders and attempts to restore Roman rule in Britain. The chapter relates events following the end of Roman rule in Britain and preceding Vortigern's alliance with the Saxons. The most significant appearance of Ambrosius is the story about Ambrosius, Vortigern, and the two dragons beneath Dinas Emrys, "Fortress of Ambrosius" in Chapters 40–42. In this account, Ambrosius is still an adolescent but has supernatural powers. He intimidates Vortigern and the royal magicians. When it is revealed that Ambrosius is the son of a Roman consul, Vortigern is convinced to cede to the younger man the castle of Dinas Emrys and all the kingdoms in the western part of Britain. Vortigern then retreats to the north, in an area called Gwynessi. This story was later retold with more detail by Geoffrey of Monmouth in his fictionalised Historia Regum Britanniae, conflating the personage of Ambrosius with the Welsh tradition of Myrddin the visionary, known for oracular utterances that foretold the coming victories of the native Celtic inhabitants of Britain over the Saxons and the Normans. Geoffrey also introduces him into the Historia under the name Aurelius Ambrosius as one of three sons of Constantine III, along with Constans and Uther Pendragon. In Chapter 48, Ambrosius Aurelianus is described as "king among all the kings of the British nation". The chapter records that Pascent, the son of Vortigern, was granted rule over the regions of Buellt and Gwrtheyrnion by Ambrosius. Finally, in Chapter 66, various events are dated from a Battle of Guoloph (often identified with Wallop, ESE of Amesbury near Salisbury), which is said to have been between Ambrosius and Vitolinus. The author dates this battle as taking place 12 years from the reign of Vortigern. It is not clear how these various traditions about Ambrosius relate to each other, or whether they come from the same tradition; it is very possible that these references are to different men with the same name. Frank D. Reno points out that the works call all these men "Ambrosius"/"Emrys". The cognomen "Aurelianus" is never used. The Historia Brittonum dates the battle of Guoloph to "the twelfth year of Vortigern", by which the year 437 seems to be meant. This is perhaps a generation before the battle that Gildas may imply was commanded by Ambrosius Aurelianus. The text never identifies who Ambrosius's father is, just gives his title as a Roman consul. When an adolescent Ambrosius speaks of his father, there is no suggestion that this father is deceased. The boy is not identified as an orphan. The exact age of Ambrosius is not given in his one encounter with Vortigern. Frank D. Reno suggests that he might be as young as 13 years old, barely a teenager. It is impossible to know to what degree Ambrosius actually wielded political power, and over what area. Ambrosius and Vortigern are shown as being in conflict in the Historia Brittonum, and some historians have suspected that this preserves a historical core of the existence of two parties in opposition to one another, one headed by Ambrosius and the other by Vortigern. J. N. L. Myres built upon this suspicion and speculated that belief in Pelagianism reflected an actively provincial outlook in Britain and that Vortigern represented the Pelagian party, while Ambrosius led the Catholic one. Subsequent historians accepted Myres's speculation as fact, creating a narrative of events in 5th century Britain with various degrees of elaborate detail. Yet a simpler alternative interpretation of the conflict between these two figures is that the Historia Brittonum is preserving traditions hostile to the purported descendants of Vortigern, who at this time were a ruling house in Powys. This interpretation is supported by the negative character of all of the stories retold about Vortigern in the Historia Brittonum, which include his alleged practice of incest. The identity of Ambrosius's last mentioned enemy, Vitalinus, is somewhat obscure. Various manuscripts of the Historia and translations also render his name as "Guitolin," "Guitolini," and "Guitholini." He is mentioned in chapter 49 as one of four sons of Gloiu and co-founder of the city of Gloucester. No other background information is given. There are theories that Gloiu is also the father of Vortigern, but the genealogy is obscure and no supporting primary text can be found. There have been further attempts to identify Vitalinus with a pro-Vortigern or anti-Roman faction in Britain, opposed to the rise of the Romano-British Ambrosius. However, this is rendered problematic since Vitalinus seems to also have a Romano-British name. The traditional view of pro-Roman and pro-Briton factions active in this period might oversimplify a more complex situation. According to William of Malmesbury Ambrosius appears briefly in the Gesta Regum Anglorum ("Deeds of the Kings of the English") by William of Malmesbury. Despite its name, the work attempted to reconstruct British history in general by drawing together the varying accounts of Gildas, Bede, Nennius, and various chroniclers. The work features Ambrosius as the apparent employer of Arthur. The relevant passage has been translated as follows: William swiftly shifts attention from Ambrosius to Arthur, and proceeds to narrate Arthur's supposed victory in the Battle of Badon. The narrative is probably the first to connect Ambrosius and Arthur. William had to reconcile the accounts of Gildas and Bede who implied that Ambrosius was connected to the battle, and that of Nennius which clearly stated that it was Arthur who was connected to the battle. He solved the apparent discrepancy by connecting both of them to it. Ambrosius as the king of the Britons and Arthur as his most prominent general and true victor of the battle. According to Geoffrey of Monmouth Ambrosius Aurelianus appears in later pseudo-chronicle tradition beginning with Geoffrey of Monmouth's Historia Regum Britanniae with the slightly garbled name Aurelius Ambrosius, now presented as son of a King Constantine. King Constantine's eldest son Constans is murdered at Vortigern's instigation, and the two remaining sons (Ambrosius and Uther, still very young) are quickly hustled into exile in Brittany. (This does not fit with Gildas' account, in which Ambrosius' family perished in the turmoil of the Saxon uprisings.) Later, the two brothers return from exile with a large army when Vortigern's power has faded. They destroy Vortigern and become friends with Merlin. They go on to defeat the Saxon leader Hengist in two battles at Maisbeli (probably Ballifield, near Sheffield) and Cunengeburg. Hengist is executed and Ambrosius becomes king of Britain. However, he is poisoned by his enemies, and Uther succeeds him. The text identifies the poisoner as Eopa. Judgements tend to vary wildly of the value of Geoffrey as both a historian and a literary storyteller. He has been praised for giving us detailed information about an otherwise obscure period and possibly preserving information from lost sources, and condemned for an excessive use of artistic licence and possibly inventing stories wholecloth. According to Frank D. Reno, whenever Geoffrey uses extant sources, the details in the text tend to be accurate. Assuming that he was also using sources lost to us, it may be difficult to decide which details are truthful. Reno suggests that "individual judgements" have to be made about various elements of his narrative. Geoffrey changed the word "Aurelianus" to "Aurelius", which is the name of a Roman gens. Geoffrey retains the story of Emrys and the dragons from Nennius, but identifies the figure with Merlin. Merlin is Geoffrey's version of a historical figure known as Myrddin Wyllt. Myrddin is only mentioned once in the Annales Cambriae, at an entry dated to 573. The name of Merlin is given in Latin as Ambrosius Merlinus. "Merlinus" may have been intended as the agnomen of a Roman or Romano-British individual like Ambrosius. Elements of Ambrosius Aurelianus, the traditional warrior king, are used by Geoffrey for other characters. Ambrosius' supposed supernatural powers are passed to Merlin. Geoffrey's Aurelius Ambrosius rises to the throne but dies early, passing the throne to a previously unknown brother called Uther Pendragon. The role of warrior king is shared by Uther and his son Arthur. Geoffrey also uses the character Gloiu, father of Vitalinus/Vitolinus, derived from Nennius. He names this character as a son of Claudius and appointed by his father as Duke of the Welsh. His predecessor as Duke is called Arvirargus. Assuming that Claudius and Arvirargus are supposed to be contemporaries, then this Claudius is the Roman emperor Claudius I (reigned 41–54). It seems unlikely that Claudius would have living grandsons in the 5th century, four centuries following his death. Reno suggests that Claudius II (reigned 268–270) would be a more likely "Claudius" to have living descendants in the 5th century. Geoffrey for the first time gives a genealogy of Ambrosius. He is supposedly a paternal nephew of , King of Brittany, son of Constantine and an unnamed Briton noblewoman, adoptive grandson (on his mother's side) of Guthelinus/Vitalinus, Bishop of London, younger brother of Constans and older brother of Uther Pendragon. Ambrosius and Uther are supposedly raised by their adoptive maternal grandfather Guthelinus/Vitalinus. It is not explicitly covered in Geoffrey's narrative, but this genealogy makes Constantine and his children descendants of Conan Meriadoc, legendary founder of the line of Kings of Brittany. Conan is also featured in the Historia Regum Britanniae, where he is appointed king by Roman emperor Magnus Maximus (reigned 383–388). Constantine's reign is placed by Geoffrey as following the Groans of the Britons mentioned by Gildas. Constantine is reported killed by a Pict and his reign is followed by a brief succession crisis. Candidates for the throne included all three sons of Constantine, but there were problems for their eventual rise to the throne. Constans was a monk, and Ambrosius and Uther were underage and still in their cradle. The crisis is resolved when Vortigern places Constans on the throne, and then serves as his chief adviser and power behind the throne. When Constans is killed by the Picts serving as bodyguards of Vortigern, Vortigern feigns anguish and has the killers executed. Ambrosius is still underage and Vortigern rises to the throne. The chronology offered by Geoffrey for the early life of Ambrosius contradicts Gildas and Nennius, and is also internally inconsistent. The Groans of the Britons involves an appeal by the Britons to Roman consul "Agitius". This person has been identified with Flavius Aetius (d. 454), magister militum ("master of soldiers") of the Western Roman Empire and consul of the year 446. The Groans are generally dated to the 440s and 450s, preceding the death of Aetius. If Geoffrey's Constantine rose to the throne immediately following the Groans, this would place his reign in this period. Geoffrey gives a 10-year reign for Constantine and his marriage lasts just as long. However the eldest son Constans is clearly older than 10 years by the time his father dies. He is already an adult candidate of the throne and has had time to follow a monastic career. Even assuming there is a time gap between the death of Constantine and the adulthood of Constans, his younger brothers have not aged at all in the narrative. Geoffrey's narrative has an underage Ambrosius, if not a literal infant, in the 460s. Accounts deriving from Gildas and Nennius place Ambrosius in the prime of his life in the same decade. Most telling is that Geoffrey has Vortigern rising to the throne in the 460s. Nennius places the rise of Vortigern in the year 425, and Vortigern is entirely absent in chronologies of the 460s. Suggesting that he was deceased by that time. Geoffrey's narrative includes as a major character Hengist, as leader of the Saxons. He is featured as the father of Queen Rowena and father-in-law of Vortigern. Other Saxon characters in the narrative tend to receive less attention by the writer, but their names tend to correspond to Anglo-Saxons known from other sources. Henginst's supposed son Octa is apparently Octa of Kent, a 6th-century ruler variously connected to Hengist as a son or descendant. The other son, Ebissa, is more difficult to identify. He might correspond to kinsmen of Hengist variously identified as "Ossa", "Oisc", and "Aesc". A minor Saxon character called "Cherdic" is probably Cerdic of Wessex, though elsewhere Geoffrey calls the same king "Cheldric". He actually may appear under three different names in the narrative, since Geoffrey elsewhere calls the interpreter of Hengist "Ceretic", a variant of the same name. Geoffrey, in the last chapters featuring Vortigern, has the king served by magicians. This detail derives from Nennius, though Nennius was talking about Vortigern's "wise men". They may not have been magic users but advisers. Vortigern's encounter with Emrys/Merlin takes place in this part of the narrative. Merlin warns Vortigern that Ambrosius and Uther have already sailed for Britain and are soon to arrive, apparently to claim his throne. Ambrosius soon arrives at the head of the army and is crowned king. He besieges Vortigern at the castle of "Genoreu", which is identified with Nennius' Cair Guorthigirn ("Fort Vortigern") and the hillfort at Little Doward. Ambrosius burns the castle down and Vortigern dies with it. Having killed Vortigern, Ambrosius next turns his attention to Hengist. Despite the fact that no earlier military actions of Ambrosius are recorded, the Saxons have already heard of his bravery and battle prowess. They immediately retreat beyond the Humber. Hengist soon amasses a massive army to face Ambrosius. His army counts 200,000 men and Ambrosius' only 10,000 men. He marches south and the first battle between the two armies takes place in Maisbeli, where Ambrosius emerges the victor. It is unclear what location Geoffrey had in mind. Maisbeli translates to "the field of Beli", and could be related to the Beli Mawr of Welsh legend and/or the Celtic god Belenus. Alternatively it could be a field where the Beltane festival was celebrated. Geoffrey could derive the name from a similar-sounding toponym. For example, Meicen of the Hen Ogledd ("Old North"), traditionally identified with Hatfield. Following his defeat, Hengist retreats towards Cunungeburg. Geoffrey probably had in mind Conisbrough, not far from Hatfield. Ambrosius leads his army against the new position of the Saxons. The second battle is more evenly fought, and Hengist has a chance to achieve victory. However, Ambrosius receives reinforcements from Brittany and the tide of the battle turns in favour of the Britons. Hengist himself is captured by his old enemy Eldol, Consul of Gloucester and decapitated. Soon after the battle, the surviving Saxon leaders Octa and Eosa submit themselves to Ambrosius' rule. He pardons them and grants them an area near Scotland. The area is not named, but Geoffrey could be basing this on Bernicia, a real Ango-Saxon kingdom covering areas in the modern borders of Scotland and England. Geoffrey closely connects the deaths of Vortigern and Hengist, which are elsewhere poorly recorded. Vortigern historically died in the 450s, and various dates for the death of Hengist have been proposed, between the 450s and the 480s. Octa of Kent, the supposed son and heir of Hengist, was still alive in the 6th century and seems to belong to a later historical era than his father. The ruling family of the Kingdom of Kent were called the Oiscingas, a term identifying them as descendants of Oisc of Kent, not of Hengist. In effect, none of them was likely a literal son of Hengist and their relation to Hengist may have been a later invention. Geoffrey did not invent the connection, but his sources here were likely legendary in nature. Following his victories and the end of the wars, Ambrosius organises the burial of killed nobles at Kaercaradduc. Geoffrey identifies this otherwise unknown location with Caer-Caradog (Salisbury). Ambrosius wants a permanent memorial for the slain and assigns the task to Merlin. The result is the so-called Giants' Ring. Its location in the vicinity of Salisbury has led to its identification with Stonehenge, though Geoffrey never uses that term. Stonehenge is closer to Amesbury than Salisbury. The ring formation of the monument could equally apply to Avebury, the largest stone circle in Europe. In other texts In Welsh legend and texts, Ambrosius appears as Emrys Wledig (Emperor Ambrose). The term "Wledig" is a title used by senior royal and military commanders who have achieved notable success. The term is mostly used for famous figures such as Cunedda, though a few obscure figures have been given the title. In Robert de Boron's Merlin he is called simply Pendragon and his younger brother is named Uter, which he changes to Uterpendragon after the death of the elder sibling. This is probably a confusion that entered oral tradition from Wace's Roman de Brut. Wace usually only refers to li roi ("the king") without naming him, and someone has taken an early mention of Uther's epithet Pendragon as the name of his brother. Possible identification with other figures Riothamus Léon Fleuriot has suggested Ambrosius is identical to Riothamus, a Brythonic leader who fought a major battle against the Goths in France around the year 470. Fleuriot argues that Ambrosius led the Britons in the battle, in which he was defeated and forced to retreat to Burgundy. Fleuriot proposed that he then returned to Britain to continue the war against the Saxons. Place-name evidence It has been suggested that the place-name Amesbury in Wiltshire might preserve the name of Ambrosius, and that perhaps Amesbury was the seat of his power base in the later fifth century. Scholars such as Shimon Applebaum have found a number of place names through the Midland dialect regions of Britain that incorporate the ambre- element; examples include Ombersley in Worcestershire, Ambrosden in Oxfordshire, Amberley in Herefordshire, Amberley in Gloucestershire, and Amberley in West Sussex. These scholars have claimed that this element represents an Old English word amor, the name of a woodland bird. However, Amesbury in Wiltshire is in a different dialect region and does not easily fit into the pattern of the Midland dialect place names. Modern fictional treatments The novel Coalescent by Stephen Baxter depicts Aurelianus as a general to Artorius, Briton and basis for the legend of King Arthur. In Baxter's novel, Aurelianus is a minor character who interacts with the book's main Roman-era protagonist, Regina, founder of a (literally) underground matriarchal society. In the text, he is credited with winning the battle of Mount Badon. In Marion Zimmer Bradley's The Mists of Avalon, Aurelianus is depicted as the ageing High King of Britain, a "too-ambitious" son of a Western Roman Emperor. His sister's son is Uther Pendragon, but Uther is described as not having any Roman blood. Aurelianus is unable to gather the leadership of the native Celts, who refuse to follow any but their own race. In Alfred Duggan's Conscience of the King, a historical novel about Cerdic, founder of the Anglo-Saxon kingdom of Wessex, Ambrosius Aurelianus is a Romano-British general who rose independently to military power, forming alliances with various British kings and setting out to drive the invading Saxons from Britain. Cerdic, who is of both Germanic and British descent and raised as a Roman citizen, served in his army as a young man. In the novel Ambrosius is a separate character from Arthur, or Artorius, who appears much later as a foe of Cerdic. In Stephen R. Lawhead's Pendragon Cycle, Aurelianus (most often referred to as "Aurelius") figures prominently, along with his brother Uther, in the second book of the series, Merlin. He is poisoned soon after becoming High King of Britain, and Uther succeeds him. Lawhead alters the standard Arthurian story somewhat, in that he has Aurelius marry Igraine and become the true father of King Arthur (Uther does marry his brother's widow, though). In Valerio Massimo Manfredi's The Last Legion, Aurelianus (here called "Aurelianus Ambrosius Ventidius") is a major character and is shown as one of the last loyal Romans, going to enormous lengths for his boy emperor Romulus Augustus, whose power has been wrested by the barbarian Odoacer. In this story, Romulus Augustus marries Igraine, and King Arthur is their son, and the sword of Julius Caesar becomes the legendary Excalibur in Britain. In the 2007 film version of the novel, he is played by Colin Firth and his name becomes "Aurelianus Caius Antonius". In both he is called "Aurelius" for short. Mary Stewart's The Crystal Cave follows Geoffrey of Monmouth in calling him Aurelius Ambrosius and portrays him as the father of Merlin, the elder brother of Uther (hence uncle of Arthur), an initiate of Mithras, and generally admired by everyone except the Saxons. Much of the book is set at his court in Brittany or during the campaign to retake his throne from Vortigern. Later books in the series show that Merlin's attitude toward Arthur is influenced by his belief that Arthur is a reincarnation of Ambrosius, who is seen through Merlin's eyes as a model of good kingship. In Rosemary Sutcliff's The Lantern Bearers Prince Ambrosius Aurelianus of Arfon fights the Saxons by training his British army with Roman techniques and making effective use of cavalry. By the end of the novel, the elite cavalry wing is led by his nephew, a dashing young warrior prince named Artos, whom Sutcliff postulates to be the real Arthur. In the sequel Sword at Sunset, Artos eventually succeeds an ailing Ambrosius as High King after he deliberately gets himself killed while hunting. In Parke Godwin's Firelord, Ambrosius is the elderly tribune of the diminished, dispirited and politically fractured Legio VI Victrix garrisoning Hadrian's Wall. Near his death, he names Artorius Pendragon (Arthur) as his successor, encourages him to convert the legion to alae (heavy cavalry) and allows the legionnaires to renounce their loyalty to Rome and take personal oaths of fealty to Artorius in order to help unify Brittania politically and to create a military force with the ability to quickly redeploy to meet differing threats. In Jack Whyte's Camulod Chronicles, Ambrosius Aurelianus is the half-brother of Caius Merlyn Britannicus (Merlin) and helps him lead the people of Camulod (Camelot). In Henry Treece's The Great Captains, Ambrosius is the aged and blind Count of Britain who is deposed by the Celt Artos the Bear after the latter takes his sword of command Caliburn and plunges it into a tree stump, daring him to pull it out. In Stargate SG-1, Ambrosius and Arthur are one and the same. Merlin was an Ancient, fleeing from Atlantis and later Ascends, then comes back in order to build the Sangraal, or Holy Grail, to defeat the Ori. Daniel Jackson also comments that it would mean that Ambrosius was 74 at the Battle of Mount Badon.

Andronikos II Palaiologos (; 25 March 1259 – 13 February 1332), usually Latinized as Andronicus II Palaeologus, reigned as Byzantine emperor from 1282 to 1328. Andronikos' reign was marked by the beginning of the decline of the Byzantine Empire. During his reign, the Turks conquered most of the Western Anatolian territories of the Empire and, during the last years of his reign, he also had to fight his grandson Andronikos in the First Palaiologan Civil War. The civil war ended in Andronikos II's forced abdication in 1328 after which he retired to a monastery, where he spent the last four years of his life. Life Andronikos II was born Andronikos Doukas Angelos Komnenos Palaiologos () at Nicaea. He was the eldest surviving son of Michael VIII Palaiologos and Theodora Palaiologina, grandniece of John III Doukas Vatatzes. Andronikos was acclaimed co-emperor in 1261, after his father Michael VIII recovered Constantinople from the Latin Empire, but he was not crowned until 8 November 1272. Sole emperor from 1282, Andronikos II immediately repudiated his father's unpopular Church union with the Papacy, which he had been forced to support while his father was still alive, but he was unable to resolve the related schism within the Orthodox clergy until 1310. Andronikos II was also plagued by economic difficulties. During his reign the value of the Byzantine hyperpyron depreciated precipitously, while the state treasury accumulated less than one seventh the revenue (in nominal coins) that it had previously. Seeking to increase revenue and reduce expenses, Andronikos II raised taxes, reduced tax exemptions, and dismantled the Byzantine fleet (80 ships) in 1285, thereby making the Empire increasingly dependent on the rival republics of Venice and Genoa. In 1291, he hired 50–60 Genoese ships, but the Byzantine weakness resulting from the lack of a navy became painfully apparent in the two wars with Venice in 1296–1302 and 1306–10. Later, in 1320, he tried to resurrect the navy by constructing 20 galleys, but failed. Andronikos II Palaiologos sought to resolve some of the problems facing the Byzantine Empire through diplomacy. After the death of his first wife Anne of Hungary, he married Yolanda (renamed Irene) of Montferrat, putting an end to the Montferrat claim to the Kingdom of Thessalonica. Andronikos II also attempted to marry off his son and co-emperor Michael IX Palaiologos to the Latin Empress Catherine I of Courtenay, thus seeking to eliminate Western agitation for a restoration of the Latin Empire. Another marriage alliance attempted to resolve the potential conflict with Serbia in Macedonia, as Andronikos II married off his five-year-old daughter Simonis to King Stefan Milutin in 1298. In spite of the resolution of problems in Europe, Andronikos II was faced with the collapse of the Byzantine frontier in Asia Minor, despite the successful, but short, governorships of Alexios Philanthropenos and John Tarchaneiotes. The successful military victories in Asia Minor by Alexios Philanthropenos and John Tarchaneiotes against the Turks were largely dependent on a considerable military contingent of Cretan escapees, or exiles from Venetian-occupied Crete, headed by Hortatzis, whom Michael VIII had repatriated to Byzantium through a treaty agreement with the Venetians ratified in 1277. Andronikos II had resettled those Cretans in the region of Meander river, the southeastern Asia Minor frontier of Byzantium with the Turks. After the failure of the co-emperor Michael IX to stem the Turkish advance in Asia Minor in 1302 and the disastrous Battle of Bapheus, the Byzantine government hired the Catalan Company of Almogavars (adventurers from Catalonia) led by Roger de Flor to clear Byzantine Asia Minor of the enemy. In spite of some successes, the Catalans were unable to secure lasting gains. Being more ruthless and savage than the enemy they intended to subdue they quarreled with Michael IX, and eventually openly turned on their Byzantine employers after the murder of Roger de Flor in 1305; together with a party of willing Turks they devastated Thrace, Macedonia, and Thessaly on their road to Latin occupied southern Greece. There they conquered the Duchy of Athens and Thebes. The Turks continued to penetrate the Byzantine possessions, and Prusa fell in 1326. By the end of Andronikos II's reign, much of Bithynia was in the hands of the Ottoman Turks of Osman I and his son and heir Orhan. Also, Karasids conquered Mysia-region with Paleokastron after 1296, Germiyan conquered Simav in 1328, Saruhan captured Magnesia in 1313, and Aydinids captured Smyrna in 1310. The Empire's problems were exploited by Theodore Svetoslav of Bulgaria, who defeated Michael IX and conquered much of northeastern Thrace in . The conflict ended with yet another dynastic marriage, between Michael IX's daughter Theodora and the Bulgarian emperor. The dissolute behavior of Michael IX's son Andronikos III Palaiologos led to a rift in the family, and after Michael IX's death in 1320, Andronikos II disowned his grandson, prompting a civil war that raged, with interruptions, until 1328. The conflict precipitated Bulgarian involvement, and Michael Asen III of Bulgaria attempted to capture Andronikos II under the guise of sending him military support. In 1328 Andronikos III entered Constantinople in triumph and Andronikos II was forced to abdicate. Andronikos II died as a monk at Constantinople in 1332, and was buried in the Lips Monastery. Family On 8 November 1272 Andronikos II married as his first wife Anna of Hungary, daughter of Stephen V of Hungary and Elizabeth the Cuman, with whom he had two sons: Michael IX Palaiologos (17 April 127712 October 1320). Constantine Palaiologos, despotes (1335). Constantine was forced to become a monk by his nephew Andronikos III Palaiologos. Anna died in 1281, and in 1284 Andronikos married Yolanda (renamed Irene), a daughter of William VII of Montferrat, with whom he had: John Palaiologos (–1308), despotes. Bartholomaios Palaiologos (born 1289), died young. Theodore I, Marquis of Montferrat (1291–1338). Simonis Palaiologina (1294 – after 1336), who married King Stefan Milutin of Serbia. Theodora Palaiologina (born 1295), died young. Demetrios Palaiologos (1297–1343), despotēs. Isaakios Palaiologos (born 1299), died young. Andronikos II also had at least three illegitimate daughters: Irene, who first married Ghazan, Khan of Persia, and laterJohn II Doukas, ruler of Thessaly. Maria, who married Toqta, Khan of the Golden Horde. A daughter known as Despina Khatun, who married Öljaitü, Khan of the Ilkhanate.

Actium or Aktion () was a town on a promontory in ancient Acarnania at the entrance of the Ambraciot Gulf, off which Octavian gained his celebrated victory, the Battle of Actium, over Antony and Cleopatra, on September 2, 31 BCE. History Actium belonged originally to the Corinthian colonists of Anactorium, who probably founded the sanctuary of Apollo Actius. This temple was of great antiquity. In the 3rd century BCE it fell to the Acarnanians, who subsequently held their religious summits there. There was also an ancient festival named Actia, celebrated here in honour of the god. Augustus after his victory enlarged the temple, and revived the ancient festival, which was henceforth celebrated once in five years (πενταετηρίς, ludi quinquennales), with musical and gymnastic contests, and horse races. We learn from a Greek inscription found on the site of Actium, and which is probably prior to the time of Augustus, that the chief priest of the temple was called Ἱεραπόλος, and that his name was employed in official documents, like that of the first Archon at Athens, to mark the date. Strabo says that the temple was situated on an eminence, and that below was a plain with a grove of trees, and a dock-yard; and in another passage he describes the harbour as situated outside of the gulf. On the opposite coast of Epirus, Augustus founded the city of Nicopolis in honour of his victory. After the foundation of Nicopolis, a few buildings sprang up around the temple, and it served as a kind of suburb to Nicopolis. Archaeology On October 8, 1980, the Greek Ministry of Transport and Communications reported that shipwrecks from the Battle of Actium had been located at Actium near the entrance to the Ambracan Gulf. In Summer 2009, archaeologists discovered the ruins of the Temple of Apollo and found two statue heads, one of Apollo, one of Artemis (Diana).

Aimery of Lusignan (, , Amorí; before 11551 April 1205), erroneously referred to as Amalric or Amaury in earlier scholarship, was the first King of Cyprus, reigning from 1196 to his death. He also reigned as the King of Jerusalem from his marriage to Isabella I in 1197 to his death. He was a younger son of Hugh VIII of Lusignan, a nobleman in Poitou. After participating in a rebellion against Henry II of England in 1168, he went to the Holy Land and settled in the Kingdom of Jerusalem. His marriage to Eschiva of Ibelin (whose father was an influential nobleman) strengthened his position in the kingdom. His younger brother, Guy, married Sibylla, the sister of and heir presumptive to Baldwin IV of Jerusalem. Baldwin made Aimery the constable of Jerusalem at around 1180. He was one of the commanders of the Christian army in the Battle of Hattin, which ended with decisive defeat at the hands of the army of Saladin, the Ayyubid sultan of Egypt and Syria, on 4 July 1187. Aimery supported Guy even after he lost his claim to the Kingdom of Jerusalem according to most barons of the realm, because of the death of Sibylla and their two daughters. The new King of Jerusalem, Henry II of Champagne, arrested Aimery for a short period. After his release, he retired to Jaffa which was the fief of his elder brother, Geoffrey of Lusignan, who had left the Holy Land. After Guy died in May 1194, his vassals in Cyprus elected Aimery as their lord. He accepted the suzerainty of the Holy Roman emperor, Henry VI. With the emperor's authorization, Aimery was crowned King of Cyprus in September 1197. He soon married Henry of Champagne's widow, Isabella I of Jerusalem. He and his wife were crowned King and Queen of Jerusalem in January 1198. He signed a truce with Al-Adil I, the Ayyubid sultan of Egypt, which secured the Christian possession of the coastline from Acre to Antioch. His rule was a period of peace and stability in both of his realms. Early life Aimery was born before 1155. He was the fifth son of Hugh VIII of Lusignan and his wife, Burgundia of Rancon. His family had been noted for generations of crusaders in their native Poitou. His great-grandfather, Hugh VI of Lusignan, died in the Battle of Ramla in 1102; Aimery's grandfather, Hugh VII of Lusignan, took part in the Second Crusade. Aimery's father also came to the Holy Land and died in a Muslim prison in the 1160s. Earlier scholarship erroneously referred to him as Amalric (or Amaury, its French form), but evidences from documentaries shows he was actually called Aimericus, which is a distinct name (although it was sometimes confused with Amalricus already in the Middle Ages). Runciman and other modern historians erroneously refer to him as Amalric II of Jerusalem, because they confused his name with that of Amalric "I" of Jerusalem. Aimery joined a rebellion against Henry II of England (who also ruled Poitou) in 1168, according to Robert of Torigni's chronicle, but Henry crushed the rebellion. Aimery left for the Holy Land and settled in the Kingdom of Jerusalem. He was captured in a battle and held in captivity in Damascus. A popular tradition (which was first recorded by the 13th-century Philip of Novara and John of Ibelin) held, the King of Jerusalem, Amalric, ransomed him personally. Ernoul (whose reliability is questioned) claimed Aimery was a lover of Amalric of Jerusalem's former wife, Agnes of Courtenay. Aimery married Eschiva of Ibelin, a daughter of Baldwin of Ibelin, who was one of the most powerful noblemen in the Kingdom of Jerusalem. Amalric of Jerusalem, who died on 11 July 1174, was succeeded by his thirteen-year-old son by Agnes of Courtenay, Baldwin IV who suffered from leprosy. Aimery became a member of the royal court with his father-in-law's support. Aimery's youngest brother, Guy, married Baldwin IV's widowed sister, Sibylla, in April 1180. Ernoul wrote, it was Aimery who had spoken of his brother to her and her mother, Agnes of Courtenay, describing him as a handsome and charming young man. Aimery, continued Ernoul, hurried back to Poitou and persuaded Guy to come to the kingdom, although Sibylla had promised herself to Aimery's father-in-law. Another source, William of Tyre, did not mention that Aimery had played any role in the marriage of his brother and the King's sister. Consequently, many elements of Ernoul's report (especially Aimery's alleged journey to Poitou) were most probably invented. Constable of Jerusalem Aimery was first mentioned as Constable of Jerusalem on 24 February 1182. According to Steven Runciman and Malcolm Barber, he had already been granted the office shortly after his predecessor, Humphrey II of Toron, died in April 1179. Historian Bernard Hamilton writes that Aimery's appointment was the consequence of the growing influence of his brother and he was appointed only around 1181. Saladin, the Ayyubid sultan of Egypt and Syria, launched a campaign against the Kingdom of Jerusalem on 29 September 1183. Aimery defeated the sultan's troops in a minor skirmish with the support of his father-in-law and his brother, Balian of Ibelin. After the victory, the crusaders' main army could advance as far as a spring near Saladin's camp, forcing him to retreat nine days later. During the campaign, it turned out that most barons of the realm were unwilling to cooperate with Aimery's brother, Guy, who was the designated heir to Baldwin IV. The ailing King dismissed Guy and made his five-year-old nephew (Guy's stepson), Baldwin V, his co-ruler on 20 November 1183. In early 1185, Baldwin IV decreed that the Pope, the Holy Roman Emperor and the Kings of France and England were to be approached to choose between his sister, Sybilla, and their half-sister, Isabella, if Baldwin V died before reaching the age of majority. The leper King died in April or May 1185, his nephew in late summer of 1186. Ignoring Baldwin IV's decree, Sybilla was proclaimed queen by her supporters and she crowned her husband, Guy, king. Aimery was not listed among those who were present at the ceremony, but he obviously supported his brother and sister-in-law, according to Hamilton. As Constable, Aimery organised the army of the Kingdom of Jerusalem into units before the Battle of Hattin, which ended with the decisive victory of Saladin on 4 July 1187. Along with most commanders of the Christian army, Aimery was captured in the battlefield. During the siege of Ascalon, Saladin promised the defenders that he would set free ten persons whom they named if they surrendered. Aimery and Guy were among those whom the defenders named before surrendering on 4 September, but Saladin postponed their release until the spring of 1188. Most barons of the realm thought that Guy lost his claim to the Kingdom of Jerusalem when Sybilla and their two daughters died in late 1190, but Aimery remained loyal to his brother. Guy's opponents supported Conrad of Montferrat who married Sybilla's half-sister, Isabella in late November. An assembly of the noblemen of the realm unanimously declared Conrad the lawful king on 16 April 1192. Although Conrad was murdered twelve days later, his widow soon married Henry of Champagne, who was elected King of Jerusalem. To compensate Guy for the loss of Jerusalem, Richard I of England authorized him to purchase the island of Cyprus (that Richard had conquered in May 1191) from the Knights Templar. He was also to pay 40,000 bezants to Richard who donated the right to collect the sum from Guy to Henry of Champagne. Guy settled in Cyprus in early May. Aimery remained in the Kingdom of Jerusalem, which was reduced to a narrow strip of land along the coast of the Mediterranean Sea from Jaffa to Tyre. Henry of Champagne ordered the expulsion of the merchants from Pisa from Acre in May, because he accused them of plotting with Guy of Lusignan. After Aimery intervened on behalf of the merchants, the King had him arrested. Aimery was only released at the demand of the grand masters of the Templars and the Hospitallers. He retired to Jaffa that Richard of England had granted to Aimery's eldest brother, Geoffrey of Lusignan. Reign Lord of Cyprus Guy died in May 1194, and bequeathed Cyprus to his elder brother, Geoffrey. However Geoffrey had already returned to Poitou, thus Guy's vassals elected Aimery their new lord. Henry of Champagne demanded the right to be consulted about the succession in Cyprus, but the Cypriote noblemen ignored him. Around the same time, Henry of Champagne replaced Aimery with John of Ibelin as constable of Jerusalem. Aimery realized that the treasury of Cyprus was almost empty, because his brother had granted most landed property in the island to his supporters, according to Ernoul. He summoned his vassals to an assembly. After emphasizing that each of them owned more land than he had, he persuaded them one by one "either by force, or by friendship, or by agreement" to surrender some their rents and lands. Aimery dispatched an embassy to Pope Celestine III, asking him to set up Roman Catholic dioceses in Cyprus. He also sent his representative, Rainier of Gibelet, to the Holy Roman Emperor, Henry VI, proposing that he would acknowledge the emperor's suzerainty, if the emperor sent a royal crown to him. Aimery primarily wanted to secure the emperor's assistance against a potential Byzantine invasion of Cyprus, but he also wanted to strengthen his own legitimacy as king. Rainier of Gibelet swore loyalty to Henry VI on behalf of Aimery in Gelnhausen in October 1196. The emperor who had decided to lead a crusade to the Holy Land promised that he would personally crown Aimery king. He dispatched the archbishops of Brindisi and Trani to take a golden sceptre to Aimery as a symbol of his right to rule Cyprus. King of Cyprus Henry VI's two envoys landed in Cyprus in April or May 1196. Aimery may have adopted the title of king around that time, because Pope Celestin styled him as king already in a letter in December 1196. In the same month, the Pope set up a Roman Catholic archdiocese in Nicosia with three suffragan bishops in Famagusta, Limassol and Paphos. The Greek Orthodox bishops were not expelled, but their property and income was seized by the new Catholic prelates. Henry VI's chancellor, Conrad, Bishop of Hildesheim, crowned Aimery king in Nicosia in September 1197. Aimery did homage to the chancellor. The noblemen who owned fiefs in both Cyprus and the Kingdom of Jerusalem wanted to bring about a reconciliation between Aimery and Henry of Champagne. One of them, Baldwin of Beisan, Constable of Cyprus, persuaded Henry of Champage to visit Cyprus in early 1197. The two kings made peace, agreeing that Aimery's three sons were to marry Henry's three daughters. Henry also renounced the debt that Aimery still owed to him for Cyprus and allowed Aimery to garrison his troops at Jaffa. Aimery sent Reynald Barlais to take possession of Jaffa. Aimery again used the title of Constable of Jerusalem in November 1197, which suggests that he had also recovered that office as a consequence of his treaty with Henry of Champagne. King of two realms Henry of Champagne fell from the window in his palace and died in Acre on 10 September 1197. The aristocratic-yet-impoverished Raoul of Saint Omer was one of the possible candidates to succeed him, but the grand masters of the military orders opposed him vehemently. A few days later, Al-Adil I, the Ayyubid sultan of Egypt, occupied Jaffa. Conrad of Wittelsbach, Archbishop of Mainz, who arrived to Acre on 20 September, was the first to propose that the crown should be offered to Aimery. Since Aimery's first wife had died, he could marry the widowed Isabella I of Jerusalem, who was the queen. Although Aymar, Patriarch of Jerusalem, stated that the marriage would be uncanonical, Joscius, Archbishop of Tyre, started negotiations with Aimery who accepted the offer. The patriarch also withdrew his objections and crowned Aimery and Isabella king and queen in Tyre in January 1198. The Cypriot Army fought for the Kingdom of Jerusalem during Aimery's rule, but otherwise he administered his two realms separately. Even before his coronation, Aimery united his forces with the German crusaders who were under the command of Duke Henry I of Brabant to launch a campaign against the Ayyubid troops. They forced Al-Adil to withdraw and captured Beirut on 21 October. He laid siege to Toron, but he had to lift the siege on 2 February, because the German crusaders decided to return to the Holy Roman Empire after learning that Emperor Henry VI had died. Aimery was riding at Tyre when four German knights attacked him in March 1198. His retainers rescued him and captured the four knights. Aimery accused Raoul of Saint Omer of hiring the assailants and sentenced him to banishment without a trial by his peers. At Raoul's demand, the case was submitted to the High Court of Jerusalem which held that Aimery had unlawfully banished Raoul. Nevertheless, Raoul voluntarily left the kingdom and settled in Tripoli, because he knew that he had lost Aimery's goodwill. Aimery signed a truce with Al-Adil on 1 July 1198, securing the possession of the coast from Acre as far as to Antioch for the crusaders for five years and eight months. The Byzantine emperor, Alexios III Angelos, did not abandon the idea of recovering Cyprus. He promised that he would help a new crusade if Pope Innocent III excommunicated Aimery to enable a Byzantine invasion in 1201, but Innocent refused him, stating that the Byzantines had lost their right to Cyprus when Richard I conquered the island in 1191. Aimery kept the peace with the Muslims, even when Reynald II of Dampierre, who arrived at the head of 300 French crusaders, demanded that he launch a campaign against the Muslims in early 1202. After Aimery reminded him that more than 300 soldiers were needed to wage war against the Ayyubids, Reynald left the Kingdom of Jerusalem for the Principality of Antioch. An Egyptian emir seized a fortress near Sidon and made plundering raids against the neighboring territory. As Al-Adil failed to force the emir to respect the truce, Aimery's fleet seized 20 Egyptian ships and he invaded Al-Adil's realm. In retaliation, Al-Adil's son, Al-Mu'azzam Isa plundered the region of Acre. In May 1204, Aimery's fleet sacked a small town in the Nile Delta in Egypt. The envoys of Aimery and Al-Adil signed a new truce for six years in September 1204. Al-Adil ceded Jaffa and Ramleh to the Kingdom of Jerusalem and simplified the Christian pilgrims' visits in Jerusalem and Nazareth. After eating excess of white mullet, Aimery fell seriously ill. He died after a short illness on 1 April 1205. His six-year-old son, Hugh I, succeeded him in Cyprus; and his widow continued to rule the Kingdom of Jerusalem. Legacy Historian Mary Nickerson Hardwicke described Aimery as a "self-assured, politically astute, sometimes hard, seldom sentimentally indulgent" ruler. His rule was a period of peace and consolidation. He initiated the revision of the laws of the Kingdom of Jerusalem to specify royal prerogatives. The lawyers of the Kingdom of Jerusalem held him in high esteem. One of them, John of Ibelin emphasized that Aimery had governed both Cyprus and Jerusalem "well and wisely" until his death. Family Aimery's first wife, Eschiva of Ibelin, was the elder daughter of Baldwin of Ibelin, Lord of Mirabel and Ramleh, and Richelda of Beisan. They had five children Bourgogne, who married (1) Raymond VI of Toulouse in 1193 (div 1196 with no issue); (2) Walter of Montbéliard in 1204. Walter was the regent of Cyprus for her younger brother, Hugh I, from 1205 to 1210. Helvis, who was the wife of Raymond-Roupen, who was Prince of Antioch from 1216 to 1219. Guy, who died young John, who died young Hugh I, who married Alice of Champagne Aimery's second wife, Isabella I of Jerusalem, was the only daughter of Amalric I of Jerusalem and Maria Komnene. They had three children Sybilla, who was the second wife of Leo I, King of Armenia. Melisende, who married Bohemond IV of Antioch. Amalric, who died during childhood, 2 February 1205.

Argo Navis (the Ship Argo), or simply Argo, was a large constellation in the southern sky. The genitive was "Argus Navis", abbreviated "Arg". Flamsteed and other early modern astronomers called it Navis (the Ship), genitive "Navis", abbreviated "Nav". The constellation proved to be of unwieldy size, as it was 28% larger than the next largest constellation and had more than 160 easily visible stars. The 1755 catalogue of Nicolas Louis de Lacaille divided it into the three modern constellations that occupy much of the same area: Carina (the keel), Puppis (the poop deck) and Vela (the sails). Argo derived from the ship Argo in Greek mythology, sailed by Jason and the Argonauts to Colchis in search of the Golden Fleece. Some stars of Puppis and Vela can be seen from Mediterranean latitudes in winter and spring, the ship appearing to skim along the "river of the Milky Way." Due to precession of the equinoxes, the position of the stars from Earth's viewpoint has shifted southward, and though most of the constellation was visible in Classical times, the constellation is now not easily visible from most of the northern hemisphere. All the stars of Argo Navis are easily visible from the tropics southward, and pass near zenith from southern temperate latitudes. The brightest of these is Canopus (α Carinae), the second-brightest night-time star, now assigned to Carina. History Development of the Greek constellation Argo Navis was long-known to Greek observers, who are theorised to have derived it from Egypt around 1000 BCE. Plutarch attributed it to the Egyptian "Boat of Osiris." Some academics theorized a Sumerian origin related to the Epic of Gilgamesh, a hypothesis rejected for lack of evidence that the Sumerians or other Mesopotamian culture considered these stars, or any portion of them, to form a boat. Over time, Argo became identified exclusively with ancient Greek myth of Jason and the Argonauts. In his Almagest, Claudius Ptolemy described Argo Navis as occupying the portion of the Milky Way between Canis Major and Centaurus, and identified stars comprising such details as the "little shield", the "steering-oar", the "mast-holder", and the "stern-ornament", which continued to be reflected in cartographic representations in celestial atlases into the nineteenth century (see below). The ship appeared to rotate about the pole sternwards, so nautically in reverse. Aratus, the Greek poet / historian living in the third century BCE, noted this backward progression writing, "Argo by the Great Dog's [Canis Major's] tail is drawn; for hers is not a usual course, but backward turned she comes ...". The constituent modern constellations In modern times, Argo Navis was considered unwieldy due to its enormous size (28% larger than Hydra, the largest modern constellation). In his 1763 star atlas, Nicolas Louis de Lacaille explained that there were more than a hundred and sixty stars clearly visible to the naked eye in Navis, and so he used the set of lowercase and uppercase Latin letters three times on portions of the constellation referred to as "Argûs in carina" (Carina, the keel), "Argûs in puppi" (Puppis, the poop deck or stern), and "Argûs in velis" (Vela, the sails). Lacaille replaced Bayer's designations with new ones that followed stellar magnitudes more closely, but used only a single Greek-letter sequence and described the constellation for those stars as "Argûs". Similarly, faint unlettered stars were listed only as in "Argûs". The final breakup and abolition of Argo Navis was proposed by Sir John Herschel in 1841 and again in 1844. Despite this, the constellation remained in use in parallel with its constituent parts into the 20th century. In 1922, along with the other constellations, it received a three-letter abbreviation: Arg. The breakup and relegation to a former constellation occurred in 1930 when the IAU defined the 88 modern constellations, formally instituting Carina, Puppis, and Vela, and declaring Argo obsolete. Lacaille's designations were kept in the offspring, so Carina has α, β, and ε; Vela has γ and δ; Puppis has ζ; and so on. As a result of this breakup, Argo Navis is the only one of the 48 listed by Ptolemy in his Almagest no longer officially recognized as a single constellation. In addition, the constellation Pyxis (the mariner's compass) occupies an area near that which in antiquity was considered part of Argo's mast. Some recent authors state that modern Pyxis was part of the ancient Greek conception of Argo Navis, but magnetic compasses were unknown in ancient Greek times, nor does it appear that the stars now in Pyxis were included in the original conception of Argo Navis. Lacaille considered it a separate constellation representing a modern scientific instrument (like Microscopium and Telescopium), that he created for maps of the stars of the southern hemisphere. Pyxis was listed among his 14 new constellations, separate from Argo. In 1844, John Herschel suggested formalizing the mast as a new constellation, Malus, to replace Lacaille's Pyxis, but the idea did not catch on. Similarly, an effort by Edmond Halley to detach the "cloud of mist" at the prow of Argo Navis to form a new constellation named Robur Carolinum (Charles' Oak) in honor of King Charles II, his patron, was unsuccessful. Representations in other cultures In Vedic astronomy, Indian observers also saw the asterism as "the Boat". The Māori had several names for the constellation, including Te Waka-o-Tamarereti (the canoe of Tamarereti), Te Kohi-a-Autahi (an expression meaning "cold of autumn settling down on land and water"), and Te Kohi.

Apollo 12 (November 1424, 1969) was the sixth crewed flight in the United States Apollo program and the second to land on the Moon. It was launched on November 14, 1969, from the Kennedy Space Center, Florida. Commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. Apollo 12 would have attempted the first lunar landing had Apollo 11 failed, but after the success of Neil Armstrong's mission, Apollo 12 was postponed by two months, and other Apollo missions also put on a more relaxed schedule. More time was allotted for geologic training in preparation for Apollo 12 than for Apollo 11, Conrad and Bean making several geology field trips in preparation for their mission. Apollo 12's spacecraft and launch vehicle were almost identical to Apollo 11's. One addition was hammocks to allow Conrad and Bean to rest more comfortably on the Moon. Shortly after being launched on a rainy day at Kennedy Space Center, Apollo 12 was twice struck by lightning, causing instrumentation problems but little damage. Switching to the auxiliary power supply resolved the data relay problem, saving the mission. The outward journey to the Moon otherwise saw few problems. On November 19, Conrad and Bean achieved a precise landing at their expected location within walking distance of the Surveyor 3 robotic probe, which had landed on April 20, 1967. In making a pinpoint landing, they showed that NASA could plan future missions in the expectation that astronauts could land close to sites of scientific interest. Conrad and Bean carried the Apollo Lunar Surface Experiments Package, a group of nuclear-powered scientific instruments, as well as the first color television camera taken by an Apollo mission to the lunar surface, but transmission was lost after Bean accidentally pointed the camera at the Sun and its sensor was destroyed. On the second of two moonwalks, they visited Surveyor 3 and removed parts for return to Earth. Lunar Module Intrepid lifted off from the Moon on November 20 and docked with the command module, which subsequently traveled back to Earth. The Apollo 12 mission ended on November 24 with a successful splashdown. Crew and key Mission Control personnel The commander of the all-Navy Apollo 12 crew was Charles "Pete" Conrad, who was 39 years old at the time of the mission. After receiving a bachelor's degree in aeronautical engineering from Princeton University in 1953, he became a naval aviator, and completed United States Naval Test Pilot School at Patuxent River Naval Air Station. He was selected in the second group of astronauts in 1962, and flew on Gemini 5 in 1965, and as command pilot of Gemini 11 in 1966. Command Module Pilot Richard "Dick" Gordon, 40 years old at the time of Apollo 12, also became a naval aviator in 1953, following graduation from the University of Washington with a degree in chemistry, and completed test pilot school at Patuxent River. Selected as a Group 3 astronaut in 1963, he flew with Conrad on Gemini 11. The original Lunar Module pilot assigned to work with Conrad was Clifton C. Williams Jr., who was killed in October 1967 when the T-38 he was flying crashed near Tallahassee. When forming his crew, Conrad had wanted Alan L. Bean, a former student of his at the test pilot school, but had been told by Director of Flight Crew Operations Deke Slayton that Bean was unavailable due to an assignment to the Apollo Applications Program. After Williams's death, Conrad asked for Bean again, and this time Slayton yielded. Bean, 37 years old when the mission flew, had graduated from the University of Texas in 1955 with a degree in aeronautical engineering. Also a naval aviator, he was selected alongside Gordon in 1963, and first flew in space on Apollo 12. The three Apollo 12 crew members had backed up Apollo 9 earlier in 1969. The Apollo 12 backup crew was David R. Scott as commander, Alfred M. Worden as Command Module pilot, and James B. Irwin as Lunar Module pilot. They became the crew of Apollo 15. For Apollo, a third crew of astronauts, known as the support crew, was designated in addition to the prime and backup crews used on projects Mercury and Gemini. Slayton created the support crews because James McDivitt, who would command Apollo 9, believed that, with preparation going on in facilities across the US, meetings that needed a member of the flight crew would be missed. Support crew members were to assist as directed by the mission commander. Usually low in seniority, they assembled the mission's rules, flight plan, and checklists, and kept them updated; For Apollo 12, they were Gerald P. Carr, Edward G. Gibson and Paul J. Weitz. Flight directors were Gerry Griffin, first shift, Pete Frank, second shift, Clifford E. Charlesworth, third shift, and Milton Windler, fourth shift. Flight directors during Apollo had a one-sentence job description, "The flight director may take any actions necessary for crew safety and mission success." Capsule communicators (CAPCOMs) were Scott, Worden, Irwin, Carr, Gibson, Weitz and Don Lind. Preparation Site selection The landing site selection process for Apollo 12 was greatly informed by the site selection for Apollo 11. There were rigid standards for the possible Apollo 11 landing sites, in which scientific interest was not a major factor: they had to be close to the lunar equator and not on the periphery of the portion of the lunar surface visible from Earth; they had to be relatively flat and without major obstructions along the path the Lunar Module (LM) would fly to reach them, their suitability confirmed by photographs from Lunar Orbiter probes. Also desirable was the presence of another suitable site further west in case the mission was delayed and the sun would have risen too high in the sky at the original site for desired lighting conditions. The need for three days to recycle if a launch had to be scrubbed meant that only three of the five suitable sites found were designated as potential landing sites for Apollo 11, of which the Apollo 11 landing site in the Sea of Tranquillity was the easternmost. Since Apollo 12 was to attempt the first lunar landing if Apollo 11 failed, both sets of astronauts trained for the same sites. With the success of Apollo 11, it was initially contemplated that Apollo 12 would land at the site next further west from the Sea of Tranquility, in Sinus Medii. However, NASA planning coordinator Jack Sevier and engineers at the Manned Spaceflight Center at Houston argued for a landing close enough to the crater in which the Surveyor 3 probe had landed in 1967 to allow the astronauts to cut parts from it for return to Earth. The site was otherwise suitable, and had scientific interest. Given that Apollo 11 had landed several miles off-target, though, some NASA administrators feared Apollo 12 would land far enough away that the astronauts could not reach the probe, and the agency would be embarrassed. Nevertheless, the ability to perform pinpoint landings was essential if Apollo's exploration program was to be carried out, and on July 25, 1969, Apollo Program Manager Samuel Phillips designated what became known as Surveyor crater as the landing site, despite the unanimous opposition of members of two site selection boards. Training and preparation The Apollo 12 astronauts spent five hours in mission-specific training for every hour they expected to spend in flight on the mission, a total exceeding 1,000 hours per crew member. Conrad and Bean received more mission-specific training than Apollo 11's Neil Armstrong and Buzz Aldrin had. This was in addition to the 1,500 hours of training they received as backup crew members for Apollo 9. The Apollo 12 training included over 400 hours per crew member in simulators of the Command Module (CM) and of the LM. Some of the simulations were linked in real time to flight controllers in Mission Control. To practice landing on the Moon, Conrad flew the Lunar Landing Training Vehicle (LLTV), training in which continued to be authorized even though Armstrong had been forced to bail out of a similar vehicle in 1968, just before it crashed. Had Apollo 11 not succeeded, Apollo 12 would have flown in September 1969, but with the successful landing on the Moon, Apollo 12 was moved back to November and later Apollo missions were also put on a more relaxed schedule. Soon after being assigned as Apollo 12 crew commander, Conrad met with NASA geologists and told them that the training for lunar surface activities would be conducted much as Apollo 11's, but there was to be no publicity or involvement by the media. Conrad felt he had been abused by the press during Gemini, and the sole Apollo 11 geology field trip had turned into a near-fiasco, with a large media contingent present, some getting in the way—the astronauts had trouble hearing each other due to a hovering press helicopter. After the successful return of Apollo 11 in July 1969, more time was allotted for geology, but the astronauts' focus was in getting time in the simulators without being pre-empted by the Apollo 11 crew. On the six Apollo 12 geology field trips, the astronauts would practice as if on the Moon, collecting samples and documenting them with photographs, while communicating with a CAPCOM and geologists who were out of sight in a nearby tent. Afterwards, the astronauts' performance in choosing samples and taking photographs would be critiqued. To the frustration of the astronauts, the scientists kept changing the photo documentation procedures; after the fourth or fifth such change, Conrad required that there be no more. After the return of Apollo 11, the Apollo 12 crew was able to view the lunar samples, and be briefed on them by scientists. As Apollo 11 was targeted for an ellipse-shaped landing zone, rather than at a specific point, there was no planning for geology traverses, the designated tasks to be done at sites of the crew's choosing. For Apollo 12, before the mission, some of NASA's geology team met with the crew and Conrad suggested they lay out possible routes for him and Bean. The result was four traverses, based on four potential landing points for the LM. This was the start of geology traverse planning that on later missions became a considerable effort involving several organizations. The stages of the lunar module, LM–6, were delivered to Kennedy Space Center (KSC) on March 24, 1969, and were mated to each other on April 28. Command module CM–108 and service module SM–108 were delivered to KSC on March 28, and were mated to each other on April 21. Following installation of gear and testing, the launch vehicle, with the spacecraft atop it, was rolled out to Launch Complex 39A on September 8, 1969. The training schedule was complete, as planned, by November 1, 1969; activities after that date were intended as refreshers. The crew members felt that the training, for the most part, was adequate preparation for the Moon mission. Hardware Launch vehicle There were no significant changes to the Saturn V launch vehicle used on Apollo 12, SA–507, from that used on Apollo 11. There were another 17 instrumentation measurements in the Apollo 12 launch vehicle, bringing the number to 1,365. The entire vehicle, including the spacecraft, weighed at launch, an increase from Apollo 11's . Of this figure, the spacecraft weighed , up from on Apollo 11. After LM separation, the third stage of the Saturn V, the S-IVB, was intended to fly into solar orbit. The S-IVB auxiliary propulsion system was fired, with the intent that the Moon's gravity slingshot the stage into solar orbit. Due to an error, the S-IVB flew past the Moon at too high an altitude to achieve Earth escape velocity. It remained in a semi-stable Earth orbit until it finally escaped Earth orbit in 1971, but briefly returned to Earth orbit 31 years later. It was discovered by amateur astronomer Bill Yeung who gave it the temporary designation J002E3 before it was determined to be an artificial object. Again in solar orbit as of 2021, it may again be captured by Earth's gravity, but not at least until the 2040s. The S-IVBs used on later lunar missions were deliberately crashed into the Moon to create seismic events that would register on the seismometers left on the Moon and provide data about the Moon's structure. Spacecraft The Apollo 12 spacecraft consisted of Command Module 108 and Service Module 108 (together Command and Service Modules 108, or CSM–108), Lunar Module 6 (LM–6), a Launch Escape System (LES), and Spacecraft-Lunar Module Adapter 15 (SLA–15). The LES contained three rocket motors to propel the CM to safety in the event of an abort shortly after launch, while the SLA housed the LM and provided a structural connection between the Saturn V and the LM. The SLA was identical to Apollo 11's, while the LES differed only in the installation of a more reliable motor igniter. The CSM was given the call sign Yankee Clipper, while the LM had the call sign Intrepid. These sea-related names were selected by the all-Navy crew from several thousand proposed names submitted by employees of the prime contractors of the respective modules. George Glacken, a flight test engineer at North American Aviation, builder of the CSM, proposed Yankee Clipper as such ships had "majestically sailed the high seas with pride and prestige for a new America". Intrepid was from a suggestion by Robert Lambert, a planner at Grumman, builder of the LM, as evocative of "this nation's resolute determination for continued exploration of space, stressing our astronauts' fortitude and endurance of hardship". The differences between the CSM and LM of Apollo 11, and those of Apollo 12, were few and minor. A hydrogen separator was added to the CSM to stop the gas from entering the potable water tank—Apollo 11 had had one, though mounted on the water dispenser in the CM's cabin. Gaseous hydrogen in the water had given the Apollo 11 crew severe flatulence. Other changes included the strengthening of the recovery loop attached following splashdown, meaning that the swimmers recovering the CM would not have to attach an auxiliary loop. LM changes included a structural modification so that scientific experiment packages could be carried for deployment on the lunar surface. Two hammocks were added for greater comfort of the astronauts while resting on the Moon, and a color television camera substituted for the black and white one used on the lunar surface during Apollo 11. ALSEP The Apollo Lunar Surface Experiments Package, or ALSEP, was a suite of scientific instruments designed to be emplaced on the lunar surface by the Apollo astronauts, and thereafter operate autonomously, sending data to Earth. Development of the ALSEP was part of NASA's response to some scientists who opposed the crewed lunar landing program (they felt that robotic craft could explore the Moon more cheaply) by demonstrating that some tasks, such as deployment of the ALSEP, required humans. In 1966, a contract to design and build the ALSEPs was awarded to the Bendix Corporation Due to the limited time the Apollo 11 crew would have on the lunar surface, a smaller suite of experiments was flown, known as the Early Apollo Surface Experiment Package (EASEP). Apollo 12 was the first mission to carry an ALSEP; one would be flown on each of the subsequent lunar landing missions, though the components that were included would vary. Apollo 12's ALSEP was to be deployed at least away from the LM to protect the instruments from the debris that would be generated when the ascent stage of the LM took off to return the astronauts to lunar orbit. Apollo 12's ALSEP included a Lunar Surface Magnetometer (LSM), to measure the magnetic field at the Moon's surface, a Lunar Atmosphere Detector (LAD, also known as the Cold Cathode Ion Gauge Experiment), intended to measure the density and temperature of the thin lunar atmosphere and how it varies, a Lunar Ionosphere Detector (LID, also known as the Charged Particle Lunar Environment Experiment, or CPLEE), intended to study the charged particles in the lunar atmosphere, and the Solar Wind Spectrometer, to measure the strength and direction of the solar wind at the Moon's surface—the free-standing Solar Wind Composition Experiment, to measure what makes up the solar wind, would be deployed and then brought back to Earth by the astronauts. A Dust Detector was used to measure the accumulation of lunar dust on the equipment. Apollo 12's Passive Seismic Experiment (PSE), a seismometer, would measure moonquakes and other movements in the Moon's crust, and would be calibrated by the nearby planned impact of the ascent stage of Apollo 12's LM, an object of known mass and velocity hitting the Moon at a known location, and projected to be equivalent to the explosive force of one ton of TNT. The ALSEP experiments left on the Moon by Apollo 12 were connected to a Central Station, which contained a transmitter, receiver, timer, data processor, and equipment for power distribution and control of the experiments. The equipment was powered by SNAP-27, a radioisotope thermoelectric generator (RTG) developed by the Atomic Energy Commission. Containing plutonium, the RTG flown on Apollo 12 was the first use of atomic energy on a crewed NASA spacecraft—some NASA and military satellites had previously used similar systems. The plutonium core was brought from Earth in a cask attached to an LM landing leg, a container designed to survive re-entry in the event of an aborted mission, something NASA considered unlikely. The cask would survive re-entry on Apollo 13, sinking in the Tonga Trench of the Pacific Ocean, apparently without radioactive leakage. The Apollo 12 ALSEP experiments were activated from Earth on November 19, 1969. The LAD returned only a small amount of useful data due to the failure of its power supply soon after activation. The LSM was deactivated on June 14, 1974, as was the other LSM deployed on the Moon, from Apollo 15. All powered ALSEP experiments that remained active were deactivated on September 30, 1977, principally because of budgetary constraints. Mission highlights Launch With President Richard Nixon in attendance, the first time a current U.S. president had witnessed a crewed space launch, as well as Vice President Spiro Agnew, Apollo 12 launched as planned at 11:22:00 on November 14, 1969 (16:22:00 UT) from Kennedy Space Center. This was at the start of a launch window of three hours and four minutes to reach the Moon with optimal lighting conditions at the planned landing point. There were completely overcast rainy skies, and the vehicle encountered winds of during ascent, the strongest of any Apollo mission. There was a NASA rule against launching into a cumulonimbus cloud; this had been waived and it was later determined that the launch vehicle never entered such a cloud. Had the mission been postponed, it could have been launched on November 16 with landing at a backup site where there would be no Surveyor, but since time pressure to achieve a lunar landing had been removed by Apollo 11's success, NASA might have waited until December for the next opportunity to go to the Surveyor crater. Lightning struck the Saturn V 36.5 seconds after lift-off, triggered by the vehicle itself. The static discharge caused a voltage transient that knocked all three fuel cells offline, meaning the spacecraft was being powered entirely from its batteries, which could not supply enough current to meet demand. A second strike at 52 seconds knocked out the "8-ball" attitude indicator. The telemetry stream at Mission Control was garbled, but the Saturn V continued to fly normally; the strikes had not affected the Saturn V instrument unit guidance system, which functioned independently from the CSM. The astronauts unexpectedly had a board red with caution and warning lights, but could not tell exactly what was wrong. The Electrical, Environmental and Consumables Manager (EECOM) in Mission Control, John Aaron, remembered the telemetry failure pattern from an earlier test when a power loss caused a malfunction in the CSM signal conditioning electronics (SCE), which converted raw signals from instrumentation to data that could be displayed on Mission Control's consoles, and knew how to fix it. Aaron made a call, "Flight, EECOM. Try SCE to Aux", to switch the SCE to a backup power supply. The switch was fairly obscure, and neither Flight Director Gerald Griffin, CAPCOM Gerald P. Carr, nor Conrad knew what it was; Bean, who as LMP was the spacecraft's engineer, knew where to find it and threw the switch, after which the telemetry came back online, revealing no significant malfunctions. Bean put the fuel cells back online, and the mission continued. Once in Earth parking orbit, the crew carefully checked out their spacecraft before re-igniting the S-IVB third stage for trans-lunar injection. The lightning strikes caused no serious permanent damage. Initially, it was feared that the lightning strike could have damaged the explosive bolts that opened the Command Module's parachute compartment. The decision was made not to share this with the astronauts and to continue with the flight plan, since they would die if the parachutes failed to deploy, whether following an Earth-orbit abort or upon a return from the Moon, so nothing was to be gained by aborting. The parachutes deployed and functioned normally at the end of the mission. Outward journey After systems checks in Earth orbit, performed with great care because of the lightning strikes, the trans-lunar injection burn, made with the S-IVB, took place at 02:47:22.80 into the mission, setting Apollo 12 on course for the Moon. An hour and twenty minutes later, the CSM separated from the S-IVB, after which Gordon performed the transposition, docking and extracting maneuver to dock with the LM and separate the combined craft from the S-IVB, which was then sent on an attempt to reach solar orbit. The stage fired its engines to leave the vicinity of the spacecraft, a change from Apollo 11, where the SM's Service Propulsion System (SPS) engine was used to distance it from the S-IVB. As there were concerns the LM might have been damaged by the lightning strikes, Conrad and Bean entered it on the first day of flight to check its status, earlier than planned. They found no issues. At 30:52.44.36, the only necessary midcourse correction during the translunar coast was made, placing the craft on a hybrid, non-free-return trajectory. Previous crewed missions to lunar orbit had taken a free-return trajectory, allowing an easy return to Earth if the craft's engines did not fire to enter lunar orbit. Apollo 12 was the first crewed spacecraft to take a hybrid free-return trajectory, that would require another burn to return to Earth, but one that could be executed by the LM's Descent Propulsion System (DPS) if the SPS failed. The use of a hybrid trajectory allowed more flexibility in mission planning. It for example allowed Apollo 12 to launch in daylight and reach the planned landing spot on schedule. Use of a hybrid trajectory meant that Apollo 12 took 8 hours longer to go from trans-lunar injection to lunar orbit. Lunar orbit and Moon landing Apollo 12 entered a lunar orbit of with an SPS burn of 352.25 seconds at mission time 83:25:26.36. On the first lunar orbit, there was a television transmission that resulted in good-quality video of the lunar surface. On the third lunar orbit, there was another burn to circularize the craft's orbit to , and on the next revolution, preparations began for the lunar landing. The CSM and LM undocked at 107:54:02.3; a half hour later there was a burn by the CSM to separate them. The 14.4 second burn by some of the CSM's thrusters meant that the two craft would be apart when the LM began the burn to move to a lower orbit in preparation for landing on the Moon. The LM's Descent Propulsion System began a 29-second burn at 109:23:39.9 to move the craft to the lower orbit, from which the 717-second powered descent to the lunar surface began at 110:20:38.1. Conrad had trained to expect a pattern of craters known as "the Snowman" to be visible when the craft underwent "pitchover", with the Surveyor crater in its center, but had feared he would see nothing recognizable. He was astonished to see the Snowman right where it should be, meaning they were directly on course. He took over manual control, planning to land the LM, as he had in simulations, in an area near the Surveyor crater that had been dubbed "Pete's Parking Lot", but found it rougher than expected. He had to maneuver, and landed the LM at 110:32:36.2 (06:54:36 UT on November 19, 1969), just from the Surveyor probe. This achieved one objective of the mission, to perform a precision landing near the Surveyor craft. The lunar coordinates of the landing site were 3.01239° S latitude, 23.42157° W longitude. The landing caused high velocity sandblasting of the Surveyor probe. It was later determined that the sandblasting removed more dust than it delivered onto the Surveyor, because the probe was covered by a thin layer that gave it a tan hue as observed by the astronauts, and every portion of the surface exposed to the direct sandblasting was lightened back toward the original white color through the removal of lunar dust. Lunar surface activities When Conrad, the shortest man of the initial groups of astronauts, stepped onto the lunar surface his first words were "Whoopie! Man, that may have been a small one for Neil, but that's a long one for me." This was not an off-the-cuff remark: Conrad had made a bet with reporter Oriana Fallaci he would say these words, after she had queried whether NASA had instructed Neil Armstrong what to say as he stepped onto the Moon. Conrad later said he was never able to collect the money. To improve the quality of television pictures from the Moon, a color camera was carried on Apollo 12 (unlike the monochrome camera on Apollo 11). When Bean carried the camera to the place near the LM where it was to be set up, he inadvertently pointed it directly into the Sun, destroying the Secondary Electron Conduction (SEC) tube. Television coverage of this mission was thus terminated almost immediately. After raising a U.S. flag on the Moon, Conrad and Bean devoted much of the remainder of the first EVA to deploying the Apollo Lunar Surface Experiments Package (ALSEP). There were minor difficulties with the deployment. Bean had trouble extracting the RTG's plutonium fuel element from its protective cask, and the astronauts had to resort to the use of a hammer to hit the cask and dislodge the fuel element. Some of the ALSEP packages proved hard to deploy, though the astronauts were successful in all cases. With the PSE able to detect their footprints as they headed back to the LM, the astronauts secured a core tube full of lunar material, and collected other samples. The first EVA lasted 3 hours, 56 minutes and 3 seconds. Four possible geologic traverses had been planned, the variable being where the LM might set down. Conrad had landed it between two of these potential landing points, and during the first EVA and the rest break that followed, scientists in Houston combined two of the traverses into one that Conrad and Bean could follow from their landing point. The resultant traverse resembled a rough circle, and when the astronauts emerged from the LM some 13 hours after ending the first EVA, the first stop was Head crater, some from the LM. There, Bean noticed that Conrad's footprints showed lighter material underneath, indicating the presence of ejecta from Copernicus crater, to the north, something that scientists examining overhead photographs of the site had hoped to find. After the mission, samples from Head allowed geologists to date the impact that formed Copernicus—according to initial dating, some 810,000,000 years ago. The astronauts proceeded to Bench crater and Sharp crater and past Halo crater before arriving at Surveyor crater, where the Surveyor 3 probe had landed. Fearing treacherous footing or that the probe might topple on them, they approached Surveyor cautiously, descending into the shallow crater some distance away and then following a contour to reach the craft, but found the footing solid and the probe stable. They collected several pieces of Surveyor, including the television camera, as well as taking rocks that had been studied by television. Conrad and Bean had procured an automatic timer for their Hasselblad cameras, and had brought it with them without telling Mission Control, hoping to take a selfie of the two of them with the probe, but when the time came to use it, could not locate it among the lunar samples they had already placed in their Hand Tool Carrier. Before returning to the LM's vicinity, Conrad and Bean went to Block crater, within Surveyor crater. The second EVA lasted 3 hours, 49 minutes, 15 seconds, during which they traveled . During the EVAs, Conrad and Bean went as far as from the LM, and collected of samples. Lunar orbit solo activities After the LM's departure, Gordon had little to say as Mission Control focused on the lunar landing. Once that was accomplished, Gordon sent his congratulations and, on the next orbit, was able to spot both the LM and the Surveyor on the ground and convey their locations to Houston. During the first EVA, Gordon prepared for a plane change maneuver, a burn to alter the CSM's orbit to compensate for the rotation of the Moon, though at times he had difficulty communicating with Houston since Conrad and Bean were using the same communications circuit. Once the two moonwalkers had returned to the LM, Gordon executed the burn, which ensured he would be in the proper position to rendezvous with the LM when it launched from the Moon. While alone in orbit, Gordon performed the Lunar Multispectral Photography Experiment, using four Hasselblad cameras arranged in a ring and aimed through one of the CM's windows. With each camera having a different color filter, simultaneous photos would be taken by each, showing the appearance of lunar features at different points on the spectrum. Analysis of the images might reveal colors not visible to the naked eye or detectable with ordinary color film, and information could be obtained about the composition of sites that would not soon be visited by humans. Among the sites studied were contemplated landing points for future Apollo missions. Return LM Intrepid lifted off from the Moon at mission time 143:03:47.78, or 14:25:47 UT on November 20, 1969; after several maneuvers, CSM and LM docked three and a half hours later. At 147:59:31.6, the LM ascent stage was jettisoned, and shortly thereafter the CSM maneuvered away. Under control from Earth, the LM's remaining propellent was depleted in a burn that caused it to impact the Moon from the Apollo 12 landing point. The seismometer the astronauts had left on the lunar surface registered the resulting vibrations for more than an hour. The crew stayed another day in lunar orbit taking photographs of the surface, including of candidate sites for future Apollo landings. A second plane change maneuver was made at 159:04:45.47, lasting 19.25 seconds. The trans-Earth injection burn, to send the CSM Yankee Clipper towards home, was conducted at 172:27:16.81 and lasted 130.32 seconds. Two short midcourse correction burns were made en route. A final television broadcast was made, the astronauts answering questions submitted by the media. There was ample time for rest on the way back to Earth, One event was the photography of a solar eclipse that occurred when the Earth came between the spacecraft and the Sun; Bean described it as the most spectacular sight of the mission. Splashdown Yankee Clipper returned to Earth on November 24, 1969, at 20:58 UT (3:58pm Eastern Time, 10:58am HST), in the Pacific Ocean. The landing was hard, and a camera was dislodged and struck Bean in the forehead. After recovery by , they entered the Mobile Quarantine Facility (MQF), while lunar samples and Surveyor parts were sent ahead by air to the Lunar Receiving Laboratory (LRL) in Houston. Once the Hornet docked in Hawaii, the MQF was offloaded and flown to Ellington Air Force Base near Houston on November 29, from where it was taken to the LRL, where the astronauts remained until released from quarantine on December 10. Mission insignia The Apollo 12 mission patch shows the crew's naval background; all three astronauts at the time of the mission were U.S. Navy commanders. It features a clipper ship arriving at the Moon, representing the CM Yankee Clipper. The ship trails fire, and flies the flag of the United States. The mission name APOLLO XII and the crew names are on a wide gold border, with a small blue trim. Blue and gold are traditional U.S. Navy colors. The patch has four stars on it – one each for the three astronauts who flew the mission and one for Clifton Williams, the original LMP on Conrad's crew who was killed in 1967 and would have flown the mission. The star was placed there at the suggestion of his replacement, Bean. The insignia was designed by the crew with the aid of several employees of NASA contractors. The Apollo 12 landing area on the Moon is within the portion of the lunar surface shown on the insignia, based on a photograph of a globe of the Moon, taken by engineers. The clipper ship was based on photographs of such a ship obtained by Bean. Aftermath and spacecraft location After the mission, Conrad urged his crewmates to join him in the Skylab program, seeing in it the best chance of flying in space again. Bean did so—Conrad commanded Skylab 2, the first crewed mission to the space station, while Bean commanded Skylab 3. Gordon, though, still hoped to walk on the Moon and remained with the Apollo program, serving as backup commander of Apollo 15. He was the likely commander of Apollo 18, but that mission was canceled and he did not fly in space again. The Apollo 12 command module Yankee Clipper, was displayed at the Paris Air Show and was then placed at NASA's Langley Research Center in Hampton, Virginia; ownership was transferred to the Smithsonian in July 1971. It is on display at the Virginia Air and Space Center in Hampton. Mission Control had remotely fired the service module's thrusters after jettison, hoping to have it skip off the atmosphere and enter a high-apogee orbit, but the lack of tracking data confirming this caused it to conclude it most likely burned up in the atmosphere at the time of CM re-entry. The S-IVB is in a solar orbit that is sometimes affected by the Earth. The ascent stage of LM Intrepid impacted the Moon November 20, 1969, at 22:17:17.7 UT (5:17pm EST). In 2009, the Lunar Reconnaissance Orbiter (LRO) photographed the Apollo 12 landing site, where the descent stage, ALSEP, Surveyor3 spacecraft, and astronaut footpaths remain. In 2011, the LRO returned to the landing site at a lower altitude to take higher resolution photographs.

Atle Selberg (14 June 1917 – 6 August 2007) was a Norwegian mathematician known for his work in analytic number theory and the theory of automorphic forms, and in particular for bringing them into relation with spectral theory. He was awarded the Fields Medal in 1950 and an honorary Abel Prize in 2002. Early years Selberg was born in Langesund, Norway, the son of teacher Anna Kristina Selberg and mathematician Ole Michael Ludvigsen Selberg. Two of his three brothers, Sigmund and Henrik, were also mathematicians. His other brother, Arne, was a professor of engineering. While he was still at school he was influenced by the work of Srinivasa Ramanujan and he found an exact analytical formula for the partition function as suggested by the works of Ramanujan; however, this result was first published by Hans Rademacher. During the war he fought against the German invasion of Norway, and was imprisoned several times. He studied at the University of Oslo and completed his Ph.D. in 1943. World War II During World War II, Selberg worked in isolation due to the German occupation of Norway. After the war his accomplishments became known, including a proof that a positive proportion of the zeros of the Riemann zeta function lie on the line . After the war, he turned to sieve theory, a previously neglected topic which Selberg's work brought into prominence. In a 1947 paper he introduced the Selberg sieve, a method well adapted in particular to providing auxiliary upper bounds, and which contributed to Chen's theorem, among other important results. In 1948 Selberg submitted two papers in Annals of Mathematics in which he proved by elementary means the theorems for primes in arithmetic progression and the density of primes. This challenged the widely held view of his time that certain theorems are only obtainable with the advanced methods of complex analysis. Both results were based on his work on the asymptotic formula where for primes . He established this result by elementary means in March 1948, and by July of that year, Selberg and Paul Erdős each obtained elementary proofs of the prime number theorem, both using the asymptotic formula above as a starting point. Circumstances leading up to the proofs, as well as publication disagreements, led to a bitter dispute between the two mathematicians. For his fundamental accomplishments during the 1940s, Selberg received the 1950 Fields Medal. Institute for Advanced Study Selberg moved to the United States and worked as an associate professor at Syracuse University and later settled at the Institute for Advanced Study in Princeton, New Jersey in the 1950s where he remained until his death. During the 1950s he worked on introducing spectral theory into number theory, culminating in his development of the Selberg trace formula, the most famous and influential of his results. In its simplest form, this establishes a duality between the lengths of closed geodesics on a compact Riemann surface and the eigenvalues of the Laplacian, which is analogous to the duality between the prime numbers and the zeros of the zeta function. He was awarded the 1986 Wolf Prize in Mathematics. He was also awarded an honorary Abel Prize in 2002, its founding year, before the awarding of the regular prizes began. Selberg received many distinctions for his work in addition to the Fields Medal, the Wolf Prize and the Gunnerus Medal. He was elected to the Norwegian Academy of Science and Letters, the Royal Danish Academy of Sciences and Letters and the American Academy of Arts and Sciences. In 1972 he was awarded an honorary degree, doctor philos. honoris causa, at the Norwegian Institute of Technology, later part of Norwegian University of Science and Technology. Selberg had two children, Ingrid Selberg and Lars Selberg. Ingrid Selberg is married to playwright Mustapha Matura. He died at home in Princeton, New Jersey on 6 August 2007 of heart failure.

Aeronautics is the science or art involved with the study, design, and manufacturing of air flight–capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "The profession of Aeronautics (which expression includes Astronautics)." While the term originally referred solely to operating the aircraft, it has since been expanded to include technology, business, and other aspects related to aircraft. The term "aviation" is sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships, and includes ballistic vehicles while "aviation" technically does not. A significant part of aeronautical science is a branch of dynamics called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. History Early ideas Attempts to fly without any real aeronautical understanding have been made from the earliest times, typically by constructing wings and jumping from a tower with crippling or lethal results. Wiser investigators sought to gain some rational understanding through the study of bird flight. Medieval Islamic Golden Age scientists such as Abbas ibn Firnas also made such studies. The founders of modern aeronautics, Leonardo da Vinci in the Renaissance and Cayley in 1799, both began their investigations with studies of bird flight. Man-carrying kites are believed to have been used extensively in ancient China. In 1282 the Italian explorer Marco Polo described the Chinese techniques then current. The Chinese also constructed small hot air balloons, or lanterns, and rotary-wing toys. An early European to provide any scientific discussion of flight was Roger Bacon, who described principles of operation for the lighter-than-air balloon and the flapping-wing ornithopter, which he envisaged would be constructed in the future. The lifting medium for his balloon would be an "aether" whose composition he did not know. In the late fifteenth century, Leonardo da Vinci followed up his study of birds with designs for some of the earliest flying machines, including the flapping-wing ornithopter and the rotating-wing helicopter. Although his designs were rational, they were not based on particularly good science. Many of his designs, such as a four-person screw-type helicopter, have severe flaws. He did at least understand that "An object offers as much resistance to the air as the air does to the object." (Newton would not publish the Third law of motion until 1687.) His analysis led to the realisation that manpower alone was not sufficient for sustained flight, and his later designs included a mechanical power source such as a spring. Da Vinci's work was lost after his death and did not reappear until it had been overtaken by the work of George Cayley. Balloon flight The modern era of lighter-than-air flight began early in the 17th century with Galileo's experiments in which he showed that air has weight. Around 1650 Cyrano de Bergerac wrote some fantasy novels in which he described the principle of ascent using a substance (dew) he supposed to be lighter than air, and descending by releasing a controlled amount of the substance. Francesco Lana de Terzi measured the pressure of air at sea level and in 1670 proposed the first scientifically credible lifting medium in the form of hollow metal spheres from which all the air had been pumped out. These would be lighter than the displaced air and able to lift an airship. His proposed methods of controlling height are still in use today; by carrying ballast which may be dropped overboard to gain height, and by venting the lifting containers to lose height. In practice de Terzi's spheres would have collapsed under air pressure, and further developments had to wait for more practicable lifting gases. From the mid-18th century the Montgolfier brothers in France began experimenting with balloons. Their balloons were made of paper, and early experiments using steam as the lifting gas were short-lived due to its effect on the paper as it condensed. Mistaking smoke for a kind of steam, they began filling their balloons with hot smoky air which they called "electric smoke" and, despite not fully understanding the principles at work, made some successful launches and in 1783 were invited to give a demonstration to the French Académie des Sciences. Meanwhile, the discovery of hydrogen led Joseph Black in c. 1780 to propose its use as a lifting gas, though practical demonstration awaited a gas tight balloon material. On hearing of the Montgolfier Brothers' invitation, the French Academy member Jacques Charles offered a similar demonstration of a hydrogen balloon. Charles and two craftsmen, the Robert brothers, developed a gas tight material of rubberised silk for the envelope. The hydrogen gas was to be generated by chemical reaction during the filling process. The Montgolfier designs had several shortcomings, not least the need for dry weather and a tendency for sparks from the fire to set light to the paper balloon. The manned design had a gallery around the base of the balloon rather than the hanging basket of the first, unmanned design, which brought the paper closer to the fire. On their free flight, De Rozier and d'Arlandes took buckets of water and sponges to douse these fires as they arose. On the other hand, the manned design of Charles was essentially modern. As a result of these exploits, the hot-air balloon became known as the Montgolfière type and the hydrogen balloon the Charlière. Charles and the Robert brothers' next balloon, La Caroline, was a Charlière that followed Jean Baptiste Meusnier's proposals for an elongated dirigible balloon, and was notable for having an outer envelope with the gas contained in a second, inner ballonet. On 19 September 1784, it completed the first flight of over 100 km, between Paris and Beuvry, despite the man-powered propulsive devices proving useless. In an attempt the next year to provide both endurance and controllability, de Rozier developed a balloon having both hot air and hydrogen gas bags, a design which was soon named after him as the Rozière. The principle was to use the hydrogen section for constant lift and to navigate vertically by heating and allowing to cool the hot air section, in order to catch the most favourable wind at whatever altitude it was blowing. The balloon envelope was made of goldbeater's skin. The first flight ended in disaster and the approach has seldom been used since. Cayley and the foundation of modern aeronautics Sir George Cayley (1773–1857) is widely acknowledged as the founder of modern aeronautics. He was first called the "father of the aeroplane" in 1846 and Henson called him the "father of aerial navigation." He was the first true scientific aerial investigator to publish his work, which included for the first time the underlying principles and forces of flight. In 1809 he began the publication of a landmark three-part treatise titled "On Aerial Navigation" (1809–1810). In it he wrote the first scientific statement of the problem, "The whole problem is confined within these limits, viz. to make a surface support a given weight by the application of power to the resistance of air." He identified the four vector forces that influence an aircraft: thrust, lift, drag and weight and distinguished stability and control in his designs. He developed the modern conventional form of the fixed-wing aeroplane having a stabilising tail with both horizontal and vertical surfaces, flying gliders both unmanned and manned. He introduced the use of the whirling arm test rig to investigate the aerodynamics of flight, using it to discover the benefits of the curved or cambered aerofoil over the flat wing he had used for his first glider. He also identified and described the importance of dihedral, diagonal bracing and drag reduction, and contributed to the understanding and design of ornithopters and parachutes. Another significant invention was the tension-spoked wheel, which he devised in order to create a light, strong wheel for aircraft undercarriage. The 19th century During the 19th century Cayley's ideas were refined, proved and expanded on, culminating in the works of Otto Lilienthal. Lilienthal was a German engineer and buisnessman who became known as the "flying man". He was the first person to make well-documented, repeated, successful flights with gliders, therefore making the idea of „heavier than air“ a reality. Newspapers and magazines published photographs of Lilienthal gliding, favourably influencing public and scientific opinion about the possibility of flying machines becoming practical. His work lead to him developing the concept of the modern wing. His flight attempts in the year 1891 are seen as the beginning of human flight and the „Lilienthal Normalsegelapparat“ is considered to be the first air plane in series production, making the Maschinenfabrik Otto Lilienthal the first air plane production company in the world. Otto Lilienthal is often referred to as either the "father of avation" or "father of flight". Other important investigators included Horatio Phillips. Branches Aeronautics may be divided into three main branches comprising Aviation, Aeronautical science and Aeronautical engineering. Aviation Aviation is the art or practice of aeronautics. Historically aviation meant only heavier-than-air flight, but nowadays it includes flying in balloons and airships. Aeronautical engineering Aeronautical engineering covers the design and construction of aircraft, including how they are powered, how they are used and how they are controlled for safe operation. A major part of aeronautical engineering is aerodynamics, the science of passing through the air. With the increasing activity in space flight, nowadays aeronautics and astronautics are often combined as aerospace engineering. Aerodynamics The science of aerodynamics deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. The study of aerodynamics falls broadly into three areas: Incompressible flow occurs where the air simply moves to avoid objects, typically at subsonic speeds below that of sound (Mach 1). Compressible flow occurs where shock waves appear at points where the air becomes compressed, typically at speeds above Mach 1. Transonic flow occurs in the intermediate speed range around Mach 1, where the airflow over an object may be locally subsonic at one point and locally supersonic at another. Rocketry A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction. Rocket engines push rockets forwards simply by throwing their exhaust backwards extremely fast. Rockets for military and recreational uses date back to at least 13th-century China. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology of the Space Age, including setting foot on the moon. Rockets are used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight and exploration of other planets. While comparatively inefficient for low speed use, they are very lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency. Chemical rockets are the most common type of rocket and they typically create their exhaust by the combustion of rocket propellant. Chemical rockets store a large amount of energy in an easily released form, and can be very dangerous. However, careful design, testing, construction and use minimizes risks.

Angela Maria "Ani" DiFranco (; born September 23, 1970) is an American singer-songwriter. She has released more than 20 albums. DiFranco's music has been classified as folk rock and alternative rock, although it has additional influences from punk, funk, hip hop and jazz. She has released all her albums on her own record label, Righteous Babe. DiFranco supports many social and political movements by performing benefit concerts, appearing on benefit albums and speaking at rallies. Through the Righteous Babe Foundation, DiFranco has backed grassroots cultural and political organizations supporting causes including abortion rights and LGBT visibility. She counts American folk singer and songwriter Pete Seeger among her mentors. DiFranco released a memoir, No Walls and the Recurring Dream, on May 7, 2019, via Viking Books and made The New York Times Best Seller List. Early life and education DiFranco was born in Buffalo, New York, on September 23, 1970, the daughter of Elizabeth (Ross) and Dante Americo DiFranco, who had met while attending the Massachusetts Institute of Technology. Her father was of Italian descent, and her mother was from Montreal. DiFranco started playing Beatles covers at local bars and busking with her guitar teacher, Michael Meldrum, at the age of nine. By 14 she was writing her own songs. She played them at bars and coffee houses throughout her teens. DiFranco graduated from the Buffalo Academy for Visual and Performing Arts high school at 16 and began attending classes at Buffalo State College. She was living by herself, having moved out of her mother's apartment after she became an emancipated minor when she was 15. Career DiFranco started her own record company, Righteous Babe Records, in 1989 at age 19. She released her self-titled debut album in the winter of 1990, shortly after relocating to New York City. There, she took poetry classes at The New School, where she met poet Sekou Sundiata, who was to become a friend and mentor. She toured steadily for the next 15 years, pausing only to record albums. Appearances at Canadian folk festivals and increasingly larger venues in the U.S. reflected her increasing popularity on the North American folk and roots scene. Throughout the early and mid-1990s DiFranco toured solo and also as a duo with Canadian drummer Andy Stochansky. In September 1995, DiFranco participated in a concert at the Rock and Roll Hall of Fame in Cleveland Ohio, inaugurating the opening of the Woody Guthrie Archives in New York City. She later released a CD on Righteous Babe of the concert Til We Outnumber Em featuring artists such as DiFranco, Billy Bragg, Ramblin' Jack Elliott, Arlo Guthrie, Indigo Girls, Dave Pirner, Tim Robbins, and Bruce Springsteen with 100 percent of proceeds going to the Woody Guthrie Foundation and Archives and the Rock and Roll Hall of Fame Museum educational department. In 1996, bassist Sara Lee joined the touring group, whose live rapport is showcased on the 1997 album Living in Clip. DiFranco would later release Lee's solo album Make It Beautiful on Righteous Babe. In 1998, Stochansky left to pursue a solo career as a singer-songwriter. A new touring ensemble consisting of Jason Mercer on bass, Julie Wolf on keyboards, and Daren Hahn on drums, augmented at times by a horn section, accompanied DiFranco on tour between 1998 and 2002. The 1990s were a period of heightened exposure for DiFranco, as she continued playing ever larger venues around the world and attracted international attention of the press, including cover stories in Spin, Ms., and Magnet, among others, as well as appearances on MTV and VH1. Her playfully ironic cover of the Bacharach/David song "Wishin' and Hopin'" appeared under the opening titles of the film My Best Friend's Wedding. She guest starred on a 1998 episode of the Fox sitcom King of the Hill, as the voice of Peggy's feminist guitar teacher, Emily. Beginning in 1999, Righteous Babe Records began releasing albums by other artists including Sara Lee, Sekou Sundiata, Arto Lindsay, Bitch and Animal, That One Guy, Utah Phillips, Hamell on Trial, Andrew Bird, Kurt Swinghammer, Buddy Wakefield, Anaïs Mitchell and Nona Hendryx. On September 11, 2001, DiFranco was in Manhattan and later penned the poem "Self Evident" about the experience. The poem was featured in the book It's a Free Country: Personal Freedom in America After September 11. The poem's title also became the name of DiFranco's first book of poetry released exclusively in Italy by Minimum Fax. It was later also featured in Verses, a book of her poetry published in the U.S. by Seven Stories press. DiFranco has written and performed many spoken-word pieces throughout her career and was showcased as a poet on the HBO series Def Poetry in 2005. Since her 2005 release Knuckle Down (co-produced by Joe Henry) DiFranco's touring band and recordings have featured bass player Todd Sickafoose and in turns other musicians such as Allison Miller, Andy Borger, Herlin Riley, and Terence Higgins on drums and Mike Dillon on percussion and vibes. On September 11, 2007, she released the first retrospective of her career, a two disc compilation entitled Canon and simultaneously a retrospective collection of poetry book Verses. On September 30, 2008, she released Red Letter Year. In 2009, DiFranco appeared at Pete Seeger's 90th birthday celebration at Madison Square Garden, debuting her revamped version of the 1930s labor anthem "Which Side Are You On?" in a duet with Bruce Cockburn and also duetting with Kris Kristofferson on the folk classic "There's a Hole in the Bucket". DiFranco released an album on January 17, 2012, ¿Which Side Are You On?. It includes collaborations with Pete Seeger, Ivan Neville, Cyril Neville, Skerik, Adam Levy, Righteous Babe recording artist Anaïs Mitchell, CC Adcock, and a host of New Orleans-based horn players known for their work in such outfits as Galactic, Bonerama, and Rebirth Brass Band. In 2014, she released her eighteenth album, Allergic to Water. In 2017, she released her nineteenth, Binary. On May 7, 2019, DiFranco released a memoir, No Walls and the Recurring Dream, via Viking Books. It is described as a "coming-of-age story". In 2021, DiFranco released the album Revolutionary Love which was largely inspired by Valarie Kaur's book See No Stranger. Personal life DiFranco came out as bisexual in her twenties, and has written songs about love and sex with women and men. She addressed the controversy about her sexuality in the song "In or Out" on the album Imperfectly (1992). In 1998, she married her sound engineer Andrew Gilchrist in a Unitarian Universalist service in Canada. DiFranco and Gilchrist divorced in 2003. In 1990, she wrote "Lost Woman Song", which was inspired by her abortions at ages eighteen and twenty. DiFranco's father died in the summer of 2004. In July 2005, DiFranco developed tendinitis and took a nine-month hiatus from touring. In January 2007 DiFranco gave birth to her first child, a daughter, at her Buffalo home. She married the child's father, Mike Napolitano, also her regular producer, in 2009. In an interview on September 13, 2012, DiFranco mentioned that she was pregnant with her second child. In April 2013, she gave birth to her second child, a son. DiFranco has resided in the Bywater, New Orleans, neighborhood since 2008. DiFranco has described herself as an atheist. On the subject of religion, DiFranco has stated: Critical reception DiFranco has been a critical success for much of her career, with a career album average of 72 on Metacritic. Living in Clip, DiFranco's 1998 double live album, is the only one to achieve gold record status to date. DiFranco was praised by The Buffalo News in 2006 as "Buffalo's leading lady of rock music". Starting in 2003, DiFranco was nominated four consecutive times for Best Recording Package at the Grammy Awards, winning in 2004 for Evolve. On July 21, 2006, DiFranco received the Woman of Courage Award at the National Organization for Women (NOW) Conference and Young Feminist Summit in Albany, New York. DiFranco was one of the first musicians to receive the award, given each year to a woman who has set herself apart by her contributions to the feminist movement. In 2009, DiFranco received the Woody Guthrie Award for being a voice of positive social change. Music Style DiFranco's guitar playing is often characterized by a signature staccato style, rapid fingerpicking and many alternate tunings. She delivers many of her lines in a speaking style notable for its rhythmic variation. Her lyrics, which often include alliteration, metaphor, word play and a more or less gentle irony, have also received praise for their sophistication. Although DiFranco's music has been classified as both folk rock and alternative rock, she has reached across genres since her earliest albums incorporating first punk, then funk, hiphop, and jazz influences. While primarily an acoustic guitarist she has used a variety of instruments and styles: brass instrumentation was prevalent in 1998's Little Plastic Castle; a simple walking bass in her 1997 cover of Hal David and Burt Bacharach's "Wishin' and Hopin' "; strings on the 1997 live album Living in Clip and 2004's Knuckle Down; and electronics and synthesizers in 1999's To the Teeth and 2006's Reprieve. DiFranco has stated that "folk music is not an acoustic guitar – that's not where the heart of it is. I use the word 'folk' in reference to punk music and rap music. It's an attitude, it's an awareness of one's heritage, and it's a community. It's subcorporate music that gives voice to different communities and their struggle against authority." Musical collaborations, cover versions, and samples DiFranco has collaborated with a wide range of artists. In 1997, she appeared on Canadian songwriter Bruce Cockburn's Charity of Night album. In 1998, she produced fellow folksinger Dan Bern's album Fifty Eggs. She developed a deep association with folksinger and social activist Utah Phillips throughout the mid-1990s, sharing her stage and her audience with the older musician until his death in 2008 and resulting in two collaborative albums: The Past Didn't Go Anywhere (1996) and Fellow Workers (1999, with liner notes by Howard Zinn). The Past is built around Phillips's storytelling, an important part of his art that had not previously been documented on recordings; on the album, DiFranco provides musical settings for his speaking voice. The followup, Fellow Workers, was recorded live in Daniel Lanois's Kingsway Studio in New Orleans and features Phillips fronting DiFranco's touring band for a collection of songs and stories. Prince recorded two songs with DiFranco in 1999, "Providence" on her To the Teeth album, and "Eye Love U, But Eye Don't Trust U Anymore" on Prince's Rave Un2 the Joy Fantastic album. Funk and soul jazz musician Maceo Parker and rapper Corey Parker have both appeared on DiFranco's albums and featured appearances by her on theirs. Parker and Di Franco toured together in 1999. She has appeared on several compilations of the songs of Pete Seeger and frequented his Hudson Clearwater Revival Festival. In 2001, she appeared on Brazilian artist Lenine's album Falange Canibal. In 2002, her rendition of Greg Brown's "The Poet Game" appeared on Going Driftless: An Artist's Tribute to Greg Brown. Also in 2002 she recorded a duet with Jackie Chan of the Irving Gordon song "Unforgettable" for a record of unlikely collaborations, When Pigs Fly: Songs You Never Thought You'd Hear. In 2005, she appeared on Dar Williams' record My Better Self, duetting on William's cover of Pink Floyd's "Comfortably Numb". She performed with Cyndi Lauper on "Sisters of Avalon" a track from Lauper's 2005 The Body Acoustic album. In 2006, she produced Hamell on Trial's album Songs for Parents Who Enjoy Drugs. In 2008, she appeared on Todd Sickafoose's album Tiny Resisters. In 2010, she co-produced a track with Margaret Cho called "Captain Cameltoe" for the comedian's Cho Dependant album. In 2011, she appeared on Rob Wasserman's album Note of Hope, an exploration of the writings of Woody Guthrie with musical accompaniment, though the track in which she appeared, "Voice", was actually recorded 13 years earlier. Also in 2011 she duetted with Greg Dulli on the Twilight Singers record Dynamite Steps. Other artists have covered and sampled DiFranco's work throughout the years. Her spoken word poem "Self Evident" was covered by Public Enemy founder Chuck D's group called Impossebulls. Alana Davis had some commercial success with DiFranco's song "32 Flavors". Samples from the track "Coming Up" were used by DJ Spooky in his album Live Without Dead Time, produced for AdBusters Magazine in 2003. In 2010, DiFranco played Persephone on Anaïs Mitchell's album Hadestown. DiFranco was approached by Zoe Boekbinder to work on their Prison Music Project, an album of collaborations between incarcerated and formerly incarcerated writers and musicians on the outside. DiFranco co-produced the project with Boekbinder and co-wrote and performed "Nowhere but Barstow and Prison." The album Long Time Gone was released on Righteous Babe Records in 2020 after ten years in the making. Lyrical content Although much of DiFranco's material is autobiographical, it is often also strongly political. Many of her songs are concerned with contemporary social issues such as racism, sexism, sexual abuse, homophobia, reproductive rights, poverty, and war. In 2008, she donated a song to Aid Still Required's CD to assist with the restoration of the devastation done to Southeast Asia from the 2004 tsunami. The combination of personal and political is partially responsible for DiFranco's early popularity among politically active college students, particularly those of the left wing, some of whom set up fan pages on the web to document DiFranco's career as early as 1994. DiFranco's rapid rise in popularity in the mid-1990s was fueled mostly by personal contact and word of mouth rather than mainstream media. Label independence Ani cites her anti-corporate ethos for the main reason she decided to start her own label. This has allowed her a considerable degree of creative freedom over the years, including, for example, providing all instrumentals and vocals and recording the album herself at her home on an analog 8-track reel to reel, and handling much of the artwork and packaging design for her 2004 album Educated Guess. She has referenced this independence from major labels in song more than once, including "The Million You Never Made" (Not a Pretty Girl), which discusses the act of turning down a lucrative contract, "The Next Big Thing" (Not So Soft), which describes an imagined meeting with a label head-hunter who evaluates the singer based on her looks, and "Napoleon" (Dilate), which sympathizes sarcastically with an unnamed friend who did sign with a label. The business grew organically starting in 1990 with the first cassette tape. Connections were made when women in colleges started duplicating and sharing tapes. Offers to play at colleges started coming in and her popularity grew largely by word of mouth and through women's groups or organizations. Zango and Goldenrod, two music distributors specializing in women's music, started carrying DiFranco's music. In general they sold music to independent music stores and women's book stores. In 1995, Righteous Babe Records signed with Koch International for DiFranco's release of Not a Pretty Girl. Her records could then be found in large and small record stores alike. DiFranco has occasionally joined with Prince in discussing publicly the problems associated with major record companies. Righteous Babe Records employs a number of people in her hometown of Buffalo. In a 1997 open letter to Ms. magazine she expressed displeasure that what she considers a way to ensure her own artistic freedom was seen by others solely in terms of its financial success. Activism From the earliest days of her career, Ani DiFranco has lent her voice and her name to a broad range of social movements, performing benefit concerts, appearing on benefit albums, speaking at rallies, and offering info table space to organizations at her concerts and the virtual equivalent on her website, among other methods and actions. In 1999, she created her own not-for-profit organization; as the Buffalo News has reported, "Through the Righteous Babe Foundation, DiFranco has backed various grassroots cultural and political organizations, supporting causes ranging from abortion rights to gay visibility." During the first Gulf War, DiFranco participated in the anti-war movement. In early 1993 she played Pete Seeger's Clearwater Folk Festival for the first time. In 1998, she was a featured performer in the Dead Man Walking benefit concert series raising money for Sister Helen Prejean's "Not in Our Name" anti-death penalty organization. DiFranco's commitment to opposing the death penalty is longstanding; she has also been a long time supporter of the Southern Center for Human Rights. During the 2000 U.S. presidential election, she actively supported and voted for Green Party candidate Ralph Nader, though in an open letter she made clear that if she lived in a swing state, she would vote for Al Gore to prevent George W. Bush from being elected. In 2004, DiFranco visited Burma in order to learn about the Burmese resistance movement and the country's fight for democracy. During her travels she met with then-detained resistance leader Aung San Suu Kyi. Her song "In The Way" was later featured on For the Lady, a benefit CD that donated all proceeds to the United States Campaign for Burma. During the 2004 presidential primaries, she supported liberal, anti-war Democrat Dennis Kucinich. Congressman Kucinich appeared on stage with her at several concerts and she spoke positively about him from the stage at many more of her concerts. After the primary season ended, and John Kerry was the clear Democratic candidate, DiFranco launched a "Vote Dammit!" tour of swing states encouraging audience members to vote. In 2005, she lobbied Congress against the proliferation of nuclear power in general and the placement of nuclear waste dumps on Indian land in particular. In 2008, she again backed Kucinich in his bid for the presidency. In 2002, Righteous Babe Records established the "Aiding Buffalo's Children" program in conjunction with members of the local community to raise funds for Buffalo's public school system. To kick off the program, DiFranco donated "a day's pay"—the performance fee from her concert that year at Shea's Performing Arts Center— to ABC and challenged her fans to do the same. Aiding Buffalo's Children has since been folded into the Community Foundation of Greater Buffalo, contributing to a variety of charitable funds. In 2005, when Hurricane Katrina devastated DiFranco's newly adopted home town of New Orleans she collected donations from fans around the world through The Righteous Babe Store website for the Katrina Piano Fund, helping musicians replace instruments lost in the hurricane, raising over $47,500 for the cause. In 2010, after the Deepwater Horizon oil spill, she performed at the "For Our Coast" benefit concert joining Marianne Faithfull, C. C. Adcock and others at the Acadiana Center for the Arts Theater in Lafayette, raising money for Gulf Aid Acadiana, and the Gulf Aid show with Lenny Kravitz, Mos Def, and others at Mardi Gras World River City in New Orleans, both shows raising money to help protect the wetlands, clean up the coast and to assist the fishermen and their families affected by the spill. DiFranco also sits on the board for The Roots of Music, founded by Rebirth Brass Band drummer Derrick Tabb. The organization provides free marching band instruction to children in the New Orleans area in addition to academic tutoring and mentoring. DiFranco joined about 500,000 people at the March for Women's Lives in DC in April 2004. As an honored guest she marched in the front row for the three-mile route, along with Margaret Cho, Janeane Garofalo, Whoopi Goldberg, Gloria Steinem and others. Later in the day, Ani played a few songs on the main stage in front of the Capitol, including "Your Next Bold Move". Scot Fisher, Righteous Babe label president and DiFranco's longtime manager, has been a longtime advocate of the preservation movement in Buffalo. In 1999, he and DiFranco purchased a decaying church on the verge of demolition in downtown Buffalo and began the lengthy process of restoring it. In 2006, the building opened its doors again, first briefly as "The Church" and then as "Babeville," housing two concert venues, the record label's business office, and Hallwalls Contemporary Arts Center. DiFranco is also a member of the Toronto-based charity Artists Against Racism for which she participated in a radio PSA.

Flavius Arcadius ( ; c. 377 – 1 May 408) was Roman emperor from 383 to 408. He was the eldest son of the Augustus Theodosius I () and his first wife Aelia Flaccilla, and the brother of Honorius (). Arcadius ruled the eastern half of the empire from 395, when their father died, while Honorius ruled the west. A weak ruler, his reign was dominated by a series of powerful ministers and by his wife, Aelia Eudoxia. Early life Birth Arcadius was born in 377 in Hispania, the eldest son of Theodosius I and Aelia Flaccilla, and brother of Honorius, who would become the Western Roman emperor. In 16 January 383, his father declared the five-year-old Arcadius an Augustus and co-ruler for the eastern half of the Empire. Later in the year a corresponding declaration made Honorius Augustus of the western half. Arcadius passed his early years under the tutelage of the rhetorician Themistius and Arsenius Zonaras, a monk. Emperor Early reign Both of Theodosius' sons were young and inexperienced, susceptible to being dominated by ambitious subordinates. In 394 Arcadius briefly exercised independent power with the help of his advisors in Constantinople, when his father Theodosius went west to fight Arbogastes and Eugenius. Theodosius died in 17 January 395, and Arcadius, still aged only 17, fell under the influence of the praetorian prefect of the East, Rufinus. Honorius, aged 10, was consigned to the guardianship of the magister militum Stilicho. Rufinus ambitiously sought to marry his daughter to Arcadius and thereby gain the prestige of being the emperor's father-in-law. However, when the prefect was called away to business in Antioch (where according to Zosimus, Rufinus had Lucianus, the comes orientis, flogged to death with whips loaded with lead), Arcadius was shown a painting of Aelia Eudoxia, the daughter of the deceased Frankish magister militum per orientem, Bauto. Seeing the young emperor's interest in Eudoxia, Eutropius, the eunuch praepositus sacri cubiculi, arranged for the two to meet. Arcadius fell in love and a marriage was quickly arranged, with the ceremony performed on 27 April 395. According to Zosimus, Rufinus assumed that his daughter was still to be the bride, only discovering otherwise when the nuptial procession went to Eudoxia's residence rather than his own. The rise of Eudoxia, facilitated by a general who was a rival of Rufinus, demonstrates the shifting of the centres of power in the eastern court. Such jostling for influence over the malleable emperor would be a recurring feature of Arcadius's reign. The first crisis facing the young Arcadius was the rebellion of the Visigoths in 395, under the command of Alaric I (), who sought to take advantage of the accession of two inexperienced Roman emperors. As Alaric marched towards Constantinople, plundering Macedonia and Thrace, the eastern court could offer no response, as the majority of its army had gone to Italy with Theodosius and was now in the hands of Stilicho. Perhaps sensing an opportunity to exercise power in the eastern half of the empire as well, Stilicho declared that Theodosius had made him guardian over both his sons. He traveled eastward, ostensibly to face Alaric, leading both his own forces and the Gothic mercenaries whom Theodosius had taken west in the civil war with Eugenius. Arcadius and Rufinus felt more threatened by Stilicho than by Alaric; upon landing in Thessaly Stilicho received an imperial order to send along the eastern regiments, but himself to proceed no further. Stilicho complied, falling back to Salona while Gainas led the mercenaries to Constantinople. Arcadius and his entourage received Gainas in the Campus Martius, a parade ground adjacent to the city, on 27 November 395. There Rufinus was suddenly assassinated by the Goths, on the orders of Stilicho and possibly with the support of Eutropius. The murder certainly created an opportunity for Eutropius and for Arcadius' wife, Eudoxia, who took Rufinus' place as advisors and guardians of the emperor. While Eutropius consolidated his hold on power in the capital, the distracted government still failed to react to the presence of Alaric in Greece. At first Eutropius may have coordinated with Stilicho around the defence of Illyricum; by 397, when Stilicho personally led a blockade that compelled Alaric to retreat into Epirus, the atmosphere of the eastern court had changed. As neither Arcadius nor Eutropius was keen to have Stilicho intervening in the affairs of the eastern empire, they provided no further military aid to Stilicho, who then abandoned the blockade of the Visigoths. At Eutropius's urging, Arcadius declared Stilicho to be a hostis publicus, and came to an arrangement with Alaric, making him magister militum per Illyricum. At around the same time, the eastern court persuaded Gildo, the magister utriusque militiae per Africam, to transfer his allegiance from Honorius to Arcadius, causing relations between the two imperial courts to deteriorate further. Eutropius' influence lasted four years, during which time he sought to marginalise the military and promote the civilian offices within the bureaucracy. He brought to trial two prominent military officers, Timasius and Abundantius. He also had Arcadius introduce two administrative innovations: the running of the cursus publicus (office of postmaster general) and the office in charge of manufacturing military equipment was transferred from the praetorian prefects to the magister officiorum (master of offices). Secondly, the role that Eutropius held, the praepositus sacri cubiculi (grand chamberlain) was given the rank of illustris, and therefore equal in rank to the praetorian prefects. In the autumn of 397 he issued a law in Arcadius's name, targeting the Roman military, where any conspiracy involving soldiers or the barbarian regiments against persons holding the rank of illustris was considered to be treason, with the conspirators to be sentenced to death, and their descendants to be deprived of citizenship. In 398, Eutropius led a successful campaign against the Huns in Roman Armenia. The following year he convinced Arcadius to grant him the consulship, triggering protests across the empire. For traditionalists, the granting of the consulship to a eunuch and former slave was an insult to the Roman system and other contemporary Romans, and the western court refused to recognize him as consul. The crisis escalated when the Ostrogoths who had been settled in Asia Minor by Theodosius I revolted, demanding the removal of Eutropius. The emperor sent two forces against Tribigild, the rebel leader; the first, under an officer named Leo, was defeated. The second force was commanded by Gainas, rival of Eutropius in the Eastern court. He returned to Arcadius and argued that the Ostrogoths could not be defeated, and that it would be sensible to accede to their demand. Arcadius viewed this proposal with displeasure, but was convinced to support it by Eudoxia, who wished to take Eutropius’ place as the main influence upon the emperor. Arcadius therefore dismissed Eutropius and sent him into exile (17 August 399), before recalling him to face trial and execution during the autumn of 399. The imperial edict issued by Arcadius detailing Eutropius's banishment survives: The Emperors Arcadius and Honorius, Augusti, to Aurelian, Praetorian Prefect. We have added to our treasury all the property of Eutropius, who was formerly the Praepositus sacri cubiculi, having stripped him of his splendour, and delivered the consulate from the foul stain of his tenure, and from the recollection of his name and the base filth thereof ; so that, all his acts having been repealed, all time may be dumb concerning him ; and that the blot of our age may not appear by the mention of him ; and that those who by their valour and wounds extend the Roman borders or guard the same by equity in the maintenance of law, may not groan over the fact that the divine reward of consulship has been befouled and defiled by a filthy monster. Let him learn that he has been deprived of the rank of the patriciate and all lower dignities that he stained with the perversity of his character. That all the statues, all the images —whether of bronze or marble, or painted in colours, or of any other material used in art—we command to be abolished in all cities, towns, private and public places, that they may not, as a brand of infamy on our age, pollute the gaze of beholders. Accordingly under the conduct of faithful guards let him be taken to the island of Cyprus, whither let your sublimity know that he has been banished ; so that therein guarded with most watchful diligence he may be unable to work confusion with his mad designs. Later reign With Eutropius' fall from power, Gainas sought to take advantage of Arcadius's current predicament. He joined the rebel Ostrogoths, and, in a face to face meeting with Arcadius, forced the emperor to make him magister militum praesentalis and Consul designate for 401. Arcadius also acquiesced when Gainas asked for the dismissal of further officials, such as the urban prefect Aurelianus, as well as a place for settlement for his troops in Thrace. However, Arcadius refused to agree to Gainas's demand for an Arian church in Constantinople for his Gothic mercenaries, following the advice of John Chrysostom, the Archbishop of Constantinople. By July 400, the actions of Gainas had irritated a significant portion of the population of Constantinople to the point that a general riot broke out in the capital. Although Gainas had stationed his troops outside of the capital walls, he was either unable or unwilling to bring them into the capital when many Goths in the city were hunted down and attacked. As many as 7,000 Goths were killed in the rioting; those who took refuge in a church were stoned and burned to death, after they received the emperor's permission, nor was it condemned by the Archbishop of Constantinople, John Chrysostom. Although initially staying his hand (probably through the intervention of the new Praetorian Prefect of the East Caesarius), Gainas eventually withdrew with his Gothic mercenaries into Thrace and rebelled against Arcadius. He attempted to take his forces across the Hellespont into Asia, but was intercepted and defeated by Fravitta, another Goth who held the position of magister militum praesentalis. Following his defeat, Gainas fled to the Danube with his remaining followers, but was ultimately defeated and killed by Uldin the Hun in Thrace. With the fall of Gainas, the next conflict emerged between Eudoxia and John Chrysostom. The Archbishop was a stern, ascetic individual, who was a vocal critic of all displays of extravagant wealth. But his ire tended to focus especially on wealthy women, and their use of clothing, jewellery and makeup as being vain and frivolous. Eudoxia assumed that Chrysostom's denunciations of extravagance in feminine dress were aimed at her. As the tensions between the two escalated, Chrysostom, who felt that Eudoxia had used her imperial connections to obtain the possessions of the wife of a condemned senator, preached a sermon in 401 in which Eudoxia was openly called Jezebel, the infamous wife of the Israelite king Ahab. Eudoxia retaliated by supporting Bishop Severian of Gabala in his conflict with Chrysostom. As Chrysostom was very popular in the capital, riots erupted in favour of the Archbishop, forcing Arcadius and Eudoxia to publicly back down and beg Chrysostom to revoke Severian's excommunication. Then in 403, Eudoxia saw another chance to strike against the Archbishop, when she threw her support behind Theophilus of Alexandria who presided over a synod in 403 (the Synod of the Oak) to charge Chrysostom with heresy. Although Arcadius originally supported Chrysostom, the Archbishop's decision not to participate caused Arcadius to change his mind and support Theophilus, resulting in Chrysostom's deposition and banishment. He was called back by Arcadius almost immediately, as the people started rioting over his departure, even threatening to burn the imperial palace. There was an earthquake the night of his arrest, which Eudoxia took for a sign of God's anger, prompting her to ask Arcadius for John's reinstatement. Peace was short-lived. In September 403 a silver statue of Eudoxia was erected in the Augustaion, near the Magna Ecclesia church. Chrysostom, who was conducting a mass at the time, denounced the noisy dedication ceremonies as pagan and spoke against the Empress in harsh terms: "Again Herodias raves; again she is troubled; she dances again; and again desires to receive John's head in a charger", an allusion to the events surrounding the death of John the Baptist. This time Arcadius was unwilling to overlook the insult to his wife; a new synod was called in early 404 where Chrysostom was condemned. Arcadius hesitated until Easter to enforce the sentence, but Chrysostom refused to go, even after Arcadius sent in a squad of soldiers to escort him into exile. Arcadius procrastinated, but by 20 June 404, the emperor finally managed to get the Archbishop to submit, and he was taken away to his place of banishment, this time to Abkhazia in the Caucasus. Eudoxia did not get to enjoy her victory for long, dying later that year. Death With the passing of Eudoxia, Arcadius once again fell under the domination of a member of his court, this time the competent Anthemius, the Praetorian Prefect. He would rule in Arcadius's name for the final four years of his reign, seeking to repair the harm done by his predecessors. He attempted to heal the divisions of the past decade by trying to make peace with Stilicho in the West. Stilicho, however, had lost patience with the eastern court, and in 407 encouraged Alaric and the Visigoths to seize the Praetorian prefecture of Illyricum and hand it over to the western empire. Stilicho's plan failed, and soon after, on 1 May 408, Arcadius died. He was succeeded by his young son, Theodosius. Like Constantine the Great and several of his successors, he was buried in the Church of the Holy Apostles, in a porphyry sarcophagus that was described in the 10th century by Constantine VII Porphyrogenitus in the De Ceremoniis. Character and achievements In noting the character of Arcadius, the historian J. B. Bury described him and his abilities thus: He was of short stature, of dark complexion, thin and inactive, and the dullness of his wit was betrayed by his speech and by his sleepy, drooping eyes. His mental deficiency and the weakness of his character made it inevitable that he should be governed by the strong personalities of his court. Traditional interpretations of the reign of Arcadius have revolved around his weakness as an Emperor, and the formulation of policy by prominent individuals (and the court parties that formed and regrouped round them) towards curtailing the increasing influence of barbarians in the military, which in Constantinople at this period meant the Goths. Scholars such as the historian J. B. Bury spoke of a group in Arcadius's court with Germanic interests and, opposed to them, a Roman faction. So when interpreting the revolt of Gainas and the massacre of the Goths in Constantinople in 400, the episode has been traditionally interpreted by scholars such as Otto Seeck as a violent anti-barbarian reaction that functioned to stabilize the East and prevent the rise of all powerful Romanised barbarian military leaders such as Stilicho in the West - what has been termed the victory of anti-Germanism in the eastern empire. The main source of this interpretation has been the works Synesius of Cyrene, specifically Aegyptus sive de providentia and De regno. Both works have traditionally been interpreted to support the thesis that there were anti-barbarian and pro-barbarian groups, with the Praetorian Prefect Aurelianus being the leader of the anti-barbarian faction. Recent scholarly research has revised this interpretation, and has instead favoured the interaction of personal ambition and enmities among the principal participants as being the leading cause for the court intrigue throughout Arcadius's reign. The gradual decline of the use of Gothic mercenaries in the eastern empire's armies that began in the reign of Arcadius was driven by recruitment issues, as the regions beyond the Danube were made inaccessible by the Huns, forcing the empire to seek recruitment in Asia Minor. The current consensus can be summarised by the historian Thomas S. Burns: "Despite much civilian distrust and outright hatred of the army and the barbarians in it, there were no anti-barbarian or pro-barbarian parties at the court." With respect to Arcadius himself, as emperor was more concerned with appearing to be a pious Christian than he was with political or military matters. Not being a military leader, he began to promote a new type of imperial victory through images, not via the traditional military achievements, but focusing on his piety. Arcadius's reign saw the growing push towards the outright abolishment of paganism. On 13 July 399, Arcadius issued an edict ordering that all remaining non-Christian temples should be immediately demolished. In terms of buildings and monuments, a new forum was built in the name of Arcadius, on the seventh hill of Constantinople, the Xērolophos, in which a column was begun to commemorate his 'victory' over Gainas (although the column was only completed after Arcadius' death by Theodosius II). The Pentelic marble portrait head of Arcadius (now in the Istanbul Archaeology Museum) was discovered in Istanbul close to the Forum Tauri, in June 1949, in excavating foundations for new buildings of the university at Beyazit. The neck was designed to be inserted in a torso, but no statue, base or inscription was found. The diadem is a fillet with rows of pearls along its edges and a rectangular stone set about with pearls over the young Emperor's forehead. A more nuanced assessment of Arcadius's reign was provided by Warren Treadgold: By failing to reign, Arcadius had allowed a good deal of maladministration. But by continuing to reign - so harmlessly that nobody had taken the trouble to depose him - he had maintained legal continuity during a troubled time. Arcadius had four children with Eudoxia: three daughters, Pulcheria, Arcadia and Marina, and one son, Theodosius, the future Emperor Theodosius II.

Afghans (, ) or Afghan people are nationals or citizens of Afghanistan, or people with ancestry from there. Concurrently the term "Afghan" can refer to someone or something of that country. Afghanistan is made up of various ethnicities, of which the Pashtuns, Tajiks, Hazaras and Uzbeks are the largest; the pre-nation state, historical ethnonym Afghan was used to refer to a member of the Pashtuns, an ethnicity that traditionally resides in the modern Afghanistan-Pakistan border region. Due to the changing political nature of the state, such as the British-drawn border with Pakistan the term has shifted to be the national identity of people from Afghanistan from all ethnicities. The two main languages spoken by Afghans are Pashto and Dari (the Afghan dialect of Persian language), and many are bilingual. Terminology The earliest mention of the name Afghan (Abgân) is by Shapur I of the Sassanid Empire during the 3rd century CE, In the 4th century the word "Afghans/Afghana" (αβγανανο) as reference to a particular people is mentioned in the Bactrian documents found in Northern Afghanistan. The word 'Afghan' is of Persian origin to refer to the Pashtun people. In the past, several scholars sought a connection with “horse,” Skt.aśva-, Av.aspa-, i.e.the Aśvaka or Aśvakayana the name of the Aśvakan or Assakan, ancient inhabitants of the Hindu Kush region, however according to some linguists, it would be extremely difficult to reconcile either Aśvaka or Aśvakayana with the world Afghan. As an adjective, the word Afghan also means "of or relating to Afghanistan or its people, language or culture". According to the 1964 Constitution of Afghanistan, all Afghans citizens are equal in rights and obligations before the law. The fourth article of the current Constitution of Afghanistan states that citizens of Afghanistan consist of Pashtun, Tajik, Hazara, Uzbek, Turkmen, Baloch, Pashayi, Nuristani, Aimaq, Arab, Kyrgyz, Qizilbash, Gurjar, Brahui, and members of other ethnicities. There are political disputes regarding this: there are members of the non-Pashtun ethnicities of Afghanistan that reject the term Afghan being applied to them, and there are Pashtuns in Pakistan that wish to have the term Afghan applied to them. Afghani, Afghanistani and Afghanese The term Afghani refers to the unit of Afghan currency. The term is also often used in the English language (and appears in some dictionaries) for a person or thing related to Afghanistan, although some have expressed the opinion that this usage is incorrect. A reason for the confusion can be because the apparent incorrect term "Afghani" (افغانی) is in fact a valid demonym for Afghans in the overall Persian language and in Hindustani, whereas "Afghan" is derived from Pashto. Thus "Afghan" is the anglicized term of "Afghani" when translating from Dari or Hindi-Urdu, but not Pashto. Less commonly the term Afghanistani has been used which, while consistent with for example Pakistani, is incorrect in practise due to the nature and origins of the term "Afghan". Another variant is Afghanese, which has been seldom used in place of Afghan. Ethnicities Afghans come from various ethnic backgrounds. Pashtuns form a plurality of the population, while Tajiks, Hazaras and Uzbeks are the next largest and altogether the four form almost 90% of the population. They are of diverse origins including of Iranian, Mongol and Turkic ethnolinguistic roots. Religions The Afghan people of all ethnicities are traditionally followers of Islam, of whom most are of the Sunni branch. Other religious minorities include the Afghan Hindus, Afghan Sikhs, Afghan Christians and Afghan Jews.

Albert Pike (December 29, 1809April 2, 1891) was an American author, poet, orator, editor, lawyer, jurist and Confederate general who served as an associate justice of the Arkansas Supreme Court in exile from 1864 to 1865. He had previously served as a senior officer of the Confederate States Army, commanding the District of Indian Territory in the Trans-Mississippi Theater. A prominent member of the Freemasons, Pike served as the Sovereign Grand Commander of the Supreme Council, Scottish Rite (Southern Jurisdiction, USA) from 1859 to 1889. Early life and education Albert Pike was born in Boston, Massachusetts, on December 29, 1809, the son of Benjamin and Sarah (Andrews) Pike, and spent his childhood in Byfield and Newburyport, Massachusetts. His colonial ancestors settled the area in 1635, and included John Pike (1613–1688/1689), the founder of Woodbridge, New Jersey. He attended school in Newburyport and Framingham until he was 15. In August 1825, he passed entrance exams at Harvard University, though when the college requested payment of tuition fees for the first two years, he chose not to attend. He began a program of self-education, later becoming a schoolteacher in Gloucester, North Bedford, Fairhaven and Newburyport. Pike was an imposing figure; tall and with hair that reached his shoulders and a long beard. In 1831, he left Massachusetts to travel west, first stopping in Nashville, Tennessee, and later moving to St. Louis, Missouri. There he joined a hunting and trading expedition to Taos, New Mexico. En route his horse broke and ran, forcing Pike to walk the remaining to Taos. After this, he joined a trapping expedition to the Llano Estacado in New Mexico and Texas. Trapping was minimal and, after traveling about , half of it on foot, he finally arrived at Fort Smith, Arkansas. Career Settling in Arkansas in 1833, Pike taught in a school and wrote a series of articles for the Little Rock Arkansas Advocate under the pen name of "Casca." The articles were sufficiently well received for him to be asked to join the newspaper's staff. Under Pike's administration, the Advocate promoted the viewpoint of the Whig Party in a politically volatile and divided Arkansas in December 1832. After marrying Mary Ann Hamilton in 1834, he purchased the newspaper. He was the first reporter for the Arkansas Supreme Court. He wrote a book (published anonymously), titled The Arkansas Form Book, which was a guidebook for lawyers. Pike began to study law and was admitted to the bar in 1837, selling the Advocate the same year. He proved to be a highly effective lawyer, representing clients in courts at every level, which continued after he received permission to practice before the United States Supreme Court in 1849. He also made several contacts among the Native American tribes in the area. He specialized in claims on behalf of Native Americans against the federal government. In 1852, he represented Creek Nation before the Supreme Court in a claim regarding ceded tribal land. In 1854 he advocated for the Choctaw and Chickasaw, although compensation later awarded to the tribes in 1856 and 1857 was insufficient. These relationships were to influence the course of his Civil War service. He also began a campaign of newspaper essays urging support for the construction of a transcontinental railroad extending from New Orleans to the Pacific coast, moving to New Orleans in 1853 and preparing to pass the state bar in furtherance of his campaign, and was ultimately able to secure a charter from the Louisiana State Legislature for a project, following which he returned to Little Rock in 1857. He joined the anti-Catholic Know Nothing Party at its founding, and, in the summer of 1854, helped introduce the party in Arkansas. He attended the national convention in 1856, but walked out when it failed to adopt a pro-slavery platform. In the lead-up to the Civil War, Pike signed a pamphlet which proposed expelling all free African Americans from Arkansas. It said that the "evil is the existence among us of a class of free colored persons". Additionally, Pike wrote on several legal subjects. He also continued writing poetry, a hobby he had begun in his youth in Massachusetts. His poems were highly regarded in his day, but are now mostly forgotten. Several volumes of his works were privately published posthumously by his daughter. In 1859, he received an honorary Master of Arts degree from Harvard. Poetry As a young man of letters, Pike wrote poetry, and he continued to do so for the rest of his life. At 23, he published his first poem, "Hymns to the Gods." Later work was printed in literary journals such as Blackwood's Edinburgh Magazine and local newspapers. His first collection of poetry, Prose Sketches and Poems Written in the Western Country, was published in 1834. He later gathered many of his poems and republished them in Hymns to the Gods and Other Poems (1872). After his death these were published again in Gen. Albert Pike's Poems (1900) and Lyrics and Love Songs (1916). The authorship of "The Old Canoe" was attributed to Pike. He was suggested as author because about the time of its publication, when it was going the rounds of the press, probably without any credit, a doggerel called "The Old Canoe" was composed about Pike by one of his political foes. The subject was a canoe in which he left Columbia, Tennessee, when a young man practicing law in that place. Pike told Senator Edward W. Carmack that he was not the author of "The Old Canoe," and could not imagine how he ever got the credit for it. The rightful author was Emily Rebecca Page. Freemasonry Pike first joined the fraternal Independent Order of Odd Fellows in 1840. He next joined a Masonic Lodge, where he became extremely active in the affairs of the organization. In 1859 he was elected Sovereign Grand Commander of the Scottish Rite's Southern Jurisdiction. He remained Sovereign Grand Commander for the rest of his life, devoting a large amount of his time to developing the rituals of the order. He published a book called Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry in 1871, the first of several editions. This helped the Order grow during the nineteenth century. He also researched and wrote the seminal treatise Indo-Aryan Deities and Worship as Contained in the Rig-Veda. In the United States, Pike is still considered an eminent and influential Freemason, primarily in the Scottish Rite Southern Jurisdiction. Military service Mexican–American War When the Mexican–American War started, Pike joined the Arkansas Mounted Infantry Regiment and was commissioned as a company commander with the rank of captain in June 1846. With his regiment, he fought in the Battle of Buena Vista. Pike was discharged in June 1847. He and his commander, Colonel John Selden Roane, had several differences of opinion. This situation led finally to an "inconclusive" duel between Pike and Roane on July 29, 1847, near Fort Smith, Arkansas. Although several shots were fired in the duel, nobody was injured, and the two were persuaded by their seconds to discontinue it. After the war, Pike returned to the practice of law, moving to New Orleans for a time beginning in 1853. He wrote another book, Maxims of the Roman Law and Some of the Ancient French Law, as Expounded and Applied in Doctrine and Jurisprudence. Although unpublished, this book increased his reputation among his associates in law. He returned to Arkansas in 1857, gaining some amount of prominence in the legal field. At the Southern Commercial Convention of 1854, Pike said the South should remain in the Union and seek equality with the North, but if the South "were forced into an inferior status, she would be better out of the Union than in it." His stand was that state's rights superseded national law and he supported the idea of a Southern secession. This stand is made clear in his pamphlet of 1861, "State or Province, Bond or Free?" American Civil War In 1861, Pike penned the lyrics to "Dixie to Arms!" At the beginning of the war, Pike was appointed as Confederate envoy to Native American nations. In this capacity he negotiated several treaties, one of the most important being with Cherokee chief John Ross, which was concluded in 1861. At the time, Ross agreed to support the Confederacy, which promised the tribes a Native American state if it won the war. Ross later changed his mind and left Indian Territory, but the succeeding Cherokee government maintained the alliance. Pike was commissioned as a brigadier general in the Confederate States Army on November 22, 1861, and given a command in the Indian Territory. With Brig. Gen. Ben McCulloch, Pike trained three Confederate regiments of Indian cavalry, most of whom belonged to the "civilized tribes", whose loyalty to the Confederacy was variable. Although initially victorious at the Battle of Pea Ridge (Elkhorn Tavern) in March 1862, Pike's unit was defeated later in a counterattack, after falling into disarray. When Pike was ordered in May 1862 to send troops to Arkansas, he resigned in protest. As in the previous war, Pike came into conflict with his superior officers, at one time drafting a letter to Jefferson Davis complaining about his direct superior. After Pea Ridge, Pike was faced with charges that his Native American troops had scalped soldiers in the field. Maj. Gen. Thomas C. Hindman also charged Pike with mishandling of money and material, ordering his arrest. Both these charges were later found to be considerably lacking in evidence; nevertheless Pike, facing arrest, escaped into the hills of Arkansas, submitting his resignation from the Confederate States Army on July 12, 1862. He was arrested on November 3 on charges of insubordination and treason, and held briefly in Warren, Texas. His resignation was accepted on November 11, and he was allowed to return to Arkansas. As Union troops advanced toward the state capital in September 1863, the State Supreme Court retreated to Washington, Arkansas, which was made the new Confederate state capital. Associate Justice Hulbert F. Fairchild resigned because the new location was too far from his family, and Pike was appointed as his replacement. In the wake of the war, Pike moved to New York City, then for a short time to Canada. On June 24, 1865, Pike applied to President Andrew Johnson for a pardon, disowning his earlier interpretation of the U.S. Constitution. He said he now planned "to pursue the arts of peace, to practice my profession, to live among my books, and to labour to benefit my fellows and my race by other than political courses". President Johnson pardoned him on April 23, 1866. Later life During the Arkansas political conflict known as the Brooks-Baxter War, Pike was one of the lawyers to speak on behalf of Elisha Baxter. Death and legacy Pike died on April 2, 1891, in Charleston, South Carolina, at the age of 81, and was buried at Oak Hill Cemetery, despite the fact that he had left instructions for his body to be cremated. In 1944, his remains were moved to the House of the Temple, headquarters of the Southern Jurisdiction of the Scottish Rite. The House of the Temple contains numerous memorials and artifacts related to Pike, including his personal library. A memorial to Pike was erected in 1901 in the Judiciary Square neighborhood of Washington, D.C. He was the only Confederate military officer with an outdoor statue in Washington, D.C., and in 2019 Delegate Eleanor Holmes Norton called for its removal. On June 19, 2020, rioters tore down the statue and set it ablaze, in connection with the George Floyd protests because of Pike's association with the Confederacy and of his alleged association with the Ku Klux Klan. The Albert Pike Memorial Temple is an historic Masonic lodge in Little Rock, Arkansas; the structure is listed on the National Register of Historic Places. Controversies In the aftermath of the Civil War, as former Confederates found themselves barred from the ballot box, Pike remained deeply opposed to black suffrage, insisting that "the white race, and that race alone, shall govern this country. It is the only one that is fit to govern, and it is the only one that shall." Regarding membership in the Freemasons, Pike is quoted as saying, "Prince Hall Lodge was as regular a Lodge as any Lodge created by competent authority. It had a perfect right to establish other Lodges and make itself a Mother Lodge. I am not inclined to meddle in the matter. I took my obligations from white men, not from negroes. When I have to accept negroes as brothers or leave masonry, I shall leave it. Better let the thing drift"; even so, Pike was the personal friend of Thornton A. Jackson, Supreme Grand Commander of the United Supreme Council, Southern Jurisdiction, Prince Hall Affiliation and even gifted to Thornton his complete set of rituals for Prince Hall Scottish Rite Masonry to use. Various histories of the Ku Klux Klan published in the early 20th century identify Pike as a high-ranking official of the order. Walter Lynwood Fleming, in 1905's Ku Klux Klan: Its Origin, Growth and Disbandment, lists Pike as the Klan's "chief judicial officer". Susan Lawrence Davis, whose father was a founding member of the Klan in Alabama, writes in her sympathetic account titled Authentic History: Ku Klux Klan, 1865-1877, published in 1924, that Pike was personally chosen by Nathan Bedford Forrest to serve as the Klan's "Chief Judicial Officer" and to head the Klan in Arkansas. In 1939's Invisible Empire: The Story of the Ku Klux Klan, 1866-1871, Stanley Horn also reports that Forrest appointed Pike and credits him with a surge of local Klan activity in April 1868. Horn says that a pro-Klan poem, Death's Brigade, is attributed to Pike. Southern Agrarian poet John Gould Fletcher, who grew up in Little Rock in a house that Pike built, also believed Pike was the poem's author. However, Walter Lee Brown in his 1997 biography, found a lack of evidence that Pike was a member of the Klan. He cites Allen W. Trelease, author of 1971's White Terror: The Ku Klux Klan Conspiracy and Southern Reconstruction, as being doubtful of Pike's membership, as the offices Pike allegedly held are not mentioned in "The Prescript", the Klan constitution. Pike's only known writing on the Klan, an 1868 editorial in the Memphis Daily Appeal, indicates that his main problems lay not with its aims, but with its methods and leadership. Later in this editorial, he proposed "one great Order of Southern Brotherhood," a secret society which would have been a larger and more centrally organized version of the Klan: "If it were in our power, if it could be effected, we would unite every white man in the South, who is opposed to negro suffrage, into one great Order of Southern Brotherhood, with an organization complete, active, vigorous, in which a few should execute the concentrated will of all, and whose very existence should be concealed from all but its members."

Ab urbe condita ( 'from the founding of the City'), or anno urbis conditae (; 'in the year since the city's founding'), abbreviated as AUC or AVC, express a date in years since 753 BC, the traditional founding of Rome. It is an expression used in antiquity and by classical historians to refer to a given year in Ancient Rome. In reference to the traditional year of the foundation of Rome, the year 1 BC would be written AUC 753, whereas AD 1 would be AUC 754. The foundation of the Roman Empire in 27 BC would be AUC 727. The current common era year 2022 coincides with the AUC year 2775. Usage of the term was more common during the Renaissance, when editors sometimes added AUC to Roman manuscripts they published, giving the false impression that the convention was commonly used in antiquity. In reality, the dominant method of identifying years in Roman times was to name the two consuls who held office that year. In late antiquity, regnal years were also in use, as in Roman Egypt during the Diocletian era after AD 293, and in the Byzantine Empire from AD 537, following a decree by Justinian. Significance The traditional date for the founding of Rome, 21 April 753 BC, is due to Marcus Terentius Varro (1st century BC). Varro may have used the consular list (with its mistakes) and called the year of the first consuls "ab Urbe condita 245," accepting the 244-year interval from Dionysius of Halicarnassus for the kings after the foundation of Rome. The correctness of this calculation has not been confirmed, but it is still used worldwide. From the time of Claudius (fl. AD 41 to AD 54) onward, this calculation superseded other contemporary calculations. Celebrating the anniversary of the city became part of imperial propaganda. Claudius was the first to hold magnificent celebrations in honor of the anniversary of the city, in AD 48, the eight hundredth year from the founding of the city. Hadrian, in AD 121, and Antoninus Pius, in AD 147 and AD 148, held similar celebrations respectively. In AD 248, Philip the Arab celebrated Rome's first millennium, together with Ludi saeculares for Rome's alleged tenth saeculum. Coins from his reign commemorate the celebrations. A coin by a contender for the imperial throne, Pacatianus, explicitly states "[y]ear one thousand and first," which is an indication that the citizens of the empire had a sense of the beginning of a new era, a Sæculum Novum. Calendar era The Anno Domini (AD) year numbering was developed by a monk named Dionysius Exiguus in Rome in AD 525, as a result of his work on calculating the date of Easter. Dionysius did not use the AUC convention, but instead based his calculations on the Diocletian era. This convention had been in use since AD 293, the year of the tetrarchy, as it became impractical to use regnal years of the current emperor. In his Easter table, the year AD 532 was equated with the 248th regnal year of Diocletian. The table counted the years starting from the presumed birth of Christ, rather than the accession of the emperor Diocletian on 20 November AD 284 or, as stated by Dionysius: "sed magis elegimus ab incarnatione Domini nostri Jesu Christi annorum tempora praenotare" ("but rather we choose to name the times of the years from the incarnation of our Lord Jesus Christ"). Blackburn and Holford-Strevens review interpretations of Dionysius which place the Incarnation in 2 BC, 1 BC, or AD 1. The year AD 1 corresponds to AUC 754, based on the epoch of Varro.

In ancient Roman religion, an aedicula (plural aediculae) is a small shrine, and in classical architecture refers to a niche covered by a pediment or entablature supported by a pair of columns and typically framing a statue. Aediculae are also represented in art as a form of ornamentation. The word aedicula is the diminutive of the Latin aedes, a temple building or dwelling place. The Latin word has been Anglicised as "aedicule" and as "edicule". Classical aediculae Many aediculae were household shrines (lararia) that held small altars or statues of the Lares and Di Penates. The Lares were Roman deities protecting the house and the family household gods. The Penates were originally patron gods (really genii) of the storeroom, later becoming household gods guarding the entire house. Other aediculae were small shrines within larger temples, usually set on a base, surmounted by a pediment and surrounded by columns. In ancient Roman architecture the aedicula has this representative function in the society. They are installed in public buildings like the triumphal arch, city gate, and thermae. The Library of Celsus in Ephesus (2. c. AD) is a good example. From the 4th century Christianization of the Roman Empire onwards such shrines, or the framework enclosing them, are often called by the Biblical term tabernacle, which becomes extended to any elaborated framework for a niche, window or picture. Gothic aediculae In Gothic architecture, too, an aedicula or tabernacle frame is a structural framing device that gives importance to its contents, whether an inscribed plaque, a cult object, a bust or the like, by assuming the tectonic vocabulary of a little building that sets it apart from the wall against which it is placed. A tabernacle frame on a wall serves similar hieratic functions as a free-standing, three-dimensional architectural baldaquin or a ciborium over an altar. In Late Gothic settings, altarpieces and devotional images were customarily crowned with gables and canopies supported by clustered-column piers, echoing in small the architecture of Gothic churches. Painted aediculae frame figures from sacred history in initial letters of illuminated manuscripts. Renaissance aediculae Classicizing architectonic structure and décor all'antica, in the "ancient [Roman] mode", became a fashionable way to frame a painted or bas-relief portrait, or protect an expensive and precious mirror during the High Renaissance; Italian precedents were imitated in France, then in Spain, England and Germany during the later 16th century. Post-Renaissance classicism Aedicular door surrounds that are architecturally treated, with pilasters or columns flanking the doorway and an entablature even with a pediment over it came into use with the 16th century. In the neo-Palladian revival in Britain, architectonic aedicular or tabernacle frames, carved and gilded, are favourite schemes for English Palladian mirror frames of the late 1720s through the 1740s, by such designers as William Kent. Other aediculae Similar small shrines, called naiskoi, are found in Greek religion, but their use was strictly religious. Aediculae exist today in Roman cemeteries as a part of funeral architecture. Presently the most famous aedicule is situated inside the Church of the Holy Sepulchre in city of Jerusalem. Contemporary American architect Charles Moore (1925–1993) used the concept of aediculae in his work to create spaces within spaces and to evoke the spiritual significance of the home.

ʿAbd al-Laṭīf al-Baghdādī (, 1162 Baghdad–1231 Baghdad), short for Muwaffaq al-Dīn Muḥammad ʿAbd al-Laṭīf ibn Yūsuf al-Baghdādī (), was a physician, philosopher, historian, Arabic grammarian and traveller, and one of the most voluminous writers of his time. Biography Many details of ʿAbd al-Laṭīf al-Baghdādī's life are known from his autobiography as presented in Ibn Abī Uṣaybiʿah's literary history of medicine. As a young man, he studied grammar, law, tradition, medicine, alchemy and philosophy. He focused his studies on ancient authors, in particular Aristotle, after first adopting Avicenna (Ibn Sīnā) as his philosophical mentor at the suggestion of a wandering scholar from the Maghreb. He travelled extensively and resided in Mosul (in 1189) where he studied the works of al-Suhrawardi before travelling on to Damascus (1190) and the camp of Saladin outside Acre (1191). It was at this last location that he met Baha al-Din ibn Shaddad and Imad al-Din al-Isfahani and acquired the Qadi al-Fadil's patronage. He went on to Cairo, where he met Abu'l-Qasim al-Shari'i, who introduced him to the works of al-Farabi, Alexander of Aphrodisias, and Themistius and (according to al-Latif) turned him away from Avicenna and alchemy. In 1192 he met Saladin in Jerusalem and enjoyed his patronage, then went to Damascus again before returning to Cairo. He journeyed to Jerusalem and to Damascus in 1207-8, and eventually made his way via Aleppo to Erzindjan, where he remained at the court of the Mengujekid Ala’-al-Din Da’ud (Dāwūd Shāh) until the city was conquered by the Rūm Seljuk ruler Kayqubād II (Kayqubād Ibn Kaykhusraw). ‘Abd al-Latif returned to Baghdad in 1229, travelling back via Erzerum, Kamakh, Divriği and Malatya. He died in Baghdad two years later. Account of Egypt ʿAbd al-Laṭīf was a man of great knowledge and of an inquisitive and penetrating mind. Of the numerous works (mostly on medicine) which Ibn Abī Uṣaybiʿah ascribes to him, one only, his graphic and detailed Account of Egypt (in two parts), appeared to be known in Europe. Archeology ʿAbd-al-Laṭīf was well aware of the value of ancient monuments. He praised Muslim rulers for preserving and protecting pre-Islamic artefacts and monuments, but he also criticized them for failing to do this. He noted that the preservation of antiquities presented a number of benefits for Muslims: "monuments are useful historical evidence for chronologies"; "they furnish evidence for Holy Scriptures, since the Qur'an mentions them and their people"; "they are reminders of human endurance and fate"; "they show, to a degree, the politics and history of ancestors, the richness of their sciences, and the genius of their thought". While discussing the profession of treasure hunting, he notes that poorer treasure hunters were often sponsored by rich businessmen to go on archeological expeditions. In some cases, an expedition could turn out to be fraudulent, with the treasure hunter disappearing with large amounts of money extracted from sponsors. Egyptology His manuscript was one of the earliest works on Egyptology. It contains a vivid description of a famine caused by the Nile failing to overflow its banks (which occurred during the author's residence in Egypt). He also wrote detailed descriptions on ancient Egyptian monuments. Autopsy Al-Baghdādī wrote that during the famine in Egypt in 597 AH (1200 AD), he had the opportunity to observe and examine a large number of skeletons, through which he came to the view that Galen was incorrect regarding the formation of the bones of the lower jaw [mandible], coccyx and sacrum. Translation Al-Baghdādī's Arabic manuscript was discovered in 1665 by the English orientalist Edward Pococke and is preserved in the Bodleian Library. Pococke published the Arabic manuscript in the 1680s. His son, Edward Pococke the Younger, translated the work into Latin, although he was only able to publish less than half of his work. Thomas Hunt attempted to publish Pococke's complete translation in 1746, although his attempt was unsuccessful. Pococke's complete Latin translation was eventually published by Joseph White of Oxford in 1800. The work was then translated into French, with valuable notes, by Silvestre de Sacy in 1810. Philosophy As far as philosophy is concerned, one may adduce that ʿAbd al-Laṭīf al-Baghdādī regarded philosophers as paragons of real virtue and therefore he refused to accept as a true philosopher one lacking not only true insight, but also a truly moral personality as true philosophy was in the service of religion, verifying both belief and action. Apart from this he regarded the philosophers’ ambitions as vain (Endress, in Martini Bonadeo, Philosophical journey, xi). ʿAbd al-Laṭīf composed several philosophical works, among which is an important and original commentary on Aristotle's Metaphysics (Kitāb fī ʿilm mā baʿd al-ṭabīʿa). This is a critical work in the process of the Arabic assimilation of Greek thought, demonstrating its author's acquaintance with the most important Greek metaphysical doctrines, as set out in the writings of al-Kindī (d. circa 185-252/801-66) and al-Fārābī (d. 339/950). The philosophical section of his Book of the Two Pieces of Advice (Kitāb al-Naṣīḥatayn) contains an interesting and challenging defence of philosophy and illustrates the vibrancy of philosophical debate in the Islamic colleges. It moreover emphasises the idea that Islamic philosophy did not decline after the twelfth century CE (Martini Bonadeo, Philosophical journey; Gutas). ʿAbd al-Laṭīf al-Baghdādī may therefore well be an exponent of what Gutas calls the “golden age of Arabic philosophy” (Gutas, 20). Alchemy ʿAbd al-Laṭīf also penned two passionate and somewhat grotesque pamphlets against the art of alchemy in all its facets. Although he engaged in alchemy for a short while, he later abandoned the art completely by rejecting not only its practice, but also its theory. In ʿAbd al-Laṭīf's view alchemy could not be placed in the system of the sciences, and its false presumptions and pretensions must be distinguished from true scientific knowledge, which can be given a rational basis (Joosse, Rebellious intellectual, 29–62; Joosse, Unmasking the craft, 301–17; Martini Bonadeo, Philosophical journey, 5-6 and 203–5; Stern, 66–7; Allemann). Spiritualism During the years following the First World War, ʿAbd al-Laṭīf al-Baghdādī's name reappeared within the spiritualistic movement in the United Kingdom. He was introduced to the public by the Irish medium Eileen J. Garrett, the author Sir Arthur Conan Doyle and the spiritualist R.H. Saunders and became known by the name Abduhl Latif, the great Arab physician. He is said to have acted as a control of mediums until the mid 1960s (Joosse, Geest, 221–9). The Bodleian Library (MS Pococke 230) and the interpretation of the Videans (Zand-Videan, 8–9) may also have prompted the whimsical short-story ‘Ghost Writer’, as told to Tim Mackintosh-Smith, in which ʿAbd al-Laṭīf al-Baghdādī speaks in the first person.

Abersychan is a town and community north of Pontypool in Torfaen, Wales, and lies within the boundaries of the historic county of Monmouthshire and the preserved county of Gwent. Abersychan lies in the narrow northern section of the Afon Lwyd valley. The town includes two schools; Abersychan Comprehensive School and Victoria Primary School; together with various shops and other amenities including Abersychan Rugby Club. Abersychan was the birthplace of the politicians Roy Jenkins, Don Touhig and Paul Murphy (MP for Torfaen); and of the rugby footballers Wilfred Hodder, Candy Evans and Bryn Meredith. History Like many of the 17th century isolated agricultural hamlets in the forested South Wales Valleys, Abersychan became a thriving industrial centre in the 19th and early 20th centuries, particularly for iron production. After the discovery of iron stone locally, the principal ironworks were built by the British Iron Company in 1825, served mainly by the LNWR's Brynmawr and Blaenavon Railway. The ironwork's main office building and quadrangle were designed by architect Decimus Burton, best known for his design of London Zoo. The works passed to the New British Iron Company in 1843 and to the Ebbw Vale Company in 1852, before closing in 1889. On 6 February 1890, an underground explosion at Llanerch Colliery killed 176. The site of the former ironworks today is a core site of , and a total land area of , includes a number of listed buildings: Abersychan Limestone Railway: built c 1830 to carry limestone from Cwm Lascarn quarry to the British Ironworks. Air Furnace at British Ironworks British Colliery Pumping Engine House: a Cornish beam pumping engine house built by the British Iron Company. Built of sandstone with a slate roof, and retains several fixtures Cwmbyrgwm Colliery: Site of former colliery including remains of a water-balance headgear, chimney, oval shafts, water power dams, tramroad routes, and waste tips. Various proposals have been made over the years to redevelop the site, currently under the ownership of HSBC, but none have so far passed the requirements of Torfaen county council. Local government Abersychan constitutes a community and electoral ward of the county borough of Torfaen. The area was part of the ancient parish of Trevethin, in Monmouthshire. On 3 June 1864 Abersychan was constituted a local government district, governed by a local board. In 1894 Abersychan became an urban district and civil parish. The urban district was abolished in 1935, with most of its area passing to Pontypool urban district, and a small area going to Abercarn UD. In 1974 the area became part of the borough of Torfaen, in the new local government county of Gwent. The community of Abersychan was formed in 1985, but no community council has yet been formed. Abersychan and Cwmavon is now a ward for the Pontypool Community Council. In 1996 Torfaen became a unitary authority. The Abersychan community includes Abersychan, Cwmavon, Garndiffaith, Pentwyn, Talywain, Varteg, and Victoria Village. Local Transport The nearest railway stations to Abersychan are Pontypool & New Inn (3 miles), Llanhilleth (3.5 miles) and Abergavenny (7 miles). Abersychan was served by the following (disused) stations: Abersychan and Talywain railway station Abersychan Low Level railway station Places nearby Pentwyn Pentwyn, Torfaen is a small village located in the district of Abersychan. It contains a post office, several houses and a small play park. The village has a cricket team (Pontnewynydd CC) and is located right next to the old railway line. The cricket club celebrated its 100-year anniversary in 2006 with a successful tour to Cork, Ireland. The village has superb views over the River Severn and Newport to the south. Victoria Village Victoria Village is a small hamlet located in the district of Abersychan. It comprises a small village school and a number of houses. A small group of houses on Incline Road mark the beginning of the village and the village boundary is near Cwmavon. Victoria Primary School is also in this area, housed in large grounds. Many homes are built around the school's boundaries. Victoria Village primary school was opened in 1903 and closed by the council in 2018. The last head of the school was Miss Joy Dando. And caretaker Miss Debbie Williams. References Towns in Torfaen Local Government Districts created by the Local Government Act 1858 Communities in Torfaen Electoral wards of Torfaen

Angiotensin-converting-enzyme inhibitors (ACE inhibitors) are a class of medication used primarily for the treatment of high blood pressure and heart failure. They work by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart. ACE inhibitors inhibit the activity of angiotensin-converting enzyme, an important component of the renin–angiotensin system which converts angiotensin I to angiotensin II, and hydrolyses bradykinin. Therefore, ACE inhibitors decrease the formation of angiotensin II, a vasoconstrictor, and increase the level of bradykinin, a peptide vasodilator. This combination is synergistic in lowering blood pressure. As a result of inhibiting the ACE enzyme in the bradykinin system, the ACE inhibitor drugs allow for increased levels of bradykinin which would normally be degraded. This mechanism can explain the two most common side effects seen with ACE Inhibitors: angioedema and cough. Bradykinin produces prostaglandin. Frequently prescribed ACE inhibitors include benazepril, zofenopril, perindopril, trandolapril, captopril, enalapril, lisinopril, and ramipril. Medical use ACE inhibitors were initially approved for the treatment of hypertension and can be used alone or in combination with other anti-hypertensive medications. Later, they were found useful for other cardiovascular and kidney diseases including: Acute myocardial infarction (heart attack) Heart failure (left ventricular systolic dysfunction) Kidney complications of diabetes mellitus (diabetic nephropathy) by means of decreasing the blood pressure and increasing perfusion in glomerular arterioles. In treating high blood pressure, ACE inhibitors are often the first drug choice, particularly when diabetes is present, but age can lead to different choices and it is common to need more than one drug to obtain the desired improvement. There are fixed-dose combination drugs, such as ACE inhibitor and thiazide combinations. ACE inhibitors have also been used in chronic kidney failure and kidney involvement in systemic sclerosis (hardening of tissues, as scleroderma renal crisis). In those with stable coronary artery disease, but no heart failure, benefits are similar to other usual treatments. In 2012, there was a meta-analysis published in the BMJ that described the protective role of ACE inhibitors in reducing the risk of pneumonia when compared to ARBs (Angiotensin II Receptor Blockers). The authors found a decreased risk in patients with previous stroke (54% risk reduction), with heart failure (37% risk reduction), and of Asian descent (43% risk reduction vs 54% risk reduction in non-Asian population). However, no reduced pneumonia related mortality was observed. Other ACE inhibitors may also be used to help decrease excessive water consumption in people with schizophrenia resulting in psychogenic polydipsia. A double-blind, placebo-controlled trial showed that when used for this purpose, enalapril led to decreased consumption (determined by urine output and osmolality) in 60% of people; the same effect has been demonstrated in other ACE inhibitors. Additionally ACEi are commonly used after renal transplant to manage post-transplant erythrocytosis, a condition characterised by a persistently high hematocrit greater than 51% which often develops 8-24 months after successful transplantation, as ACEi have been shown to decrease erythropoietin production. Adverse effects Common side effects include: low blood pressure, cough, hyperkalemia, headache, dizziness, fatigue, nausea, and kidney impairment. The main adverse effects of ACE inhibition can be understood from their pharmacological action. The other reported adverse effects are liver problems and effects on the fetus. Kidney problems may occur with all ACE inhibitors that directly follows from their mechanism of action. Patients starting on an ACE inhibitor usually have a modest reduction in glomerular filtration rate (GFR). However, the decrease may be significant in conditions of pre-existing decreased renal perfusions, such as renal artery stenosis, heart failure, polycystic kidney disease, or volume depletion. In these patients, the maintenance of GFR depends on angiotensin-II-dependent efferent vasomotor tone. Therefore, renal function should be closely monitored over the first few days after initiation of treatment with ACE inhibitor in patients with decreased renal perfusion. A moderate reduction in renal function, no greater than 30% rise in serum creatinine, that is stabilized after a week of treatment is deemed acceptable as part of the therapeutic effect, providing the residual renal function is sufficient. Reduced GFR is especially a problem if the patient is concomitantly taking an NSAID and a diuretic. When the three drugs are taken together, the risk of developing renal failure is significantly increased. High blood potassium is another possible complication of treatment with an ACE inhibitor due to its effect on aldosterone. Suppression of angiotensin II leads to a decrease in aldosterone levels. Since aldosterone is responsible for increasing the excretion of potassium, ACE inhibitors can cause retention of potassium. Some people, however, can continue to lose potassium while on an ACE inhibitor. Hyperkalemia may decrease the velocity of impulse conduction in the nerves and muscles, including cardiac tissues. This leads to cardiac dysfunction and neuromuscular consequences, such as muscle weakness, paresthesia, nausea, diarrhea, and others. Close monitoring of potassium levels is required in patients receiving treatment with ACE inhibitors who are at risk of hyperkalemia. Another possible adverse effect specific for ACE inhibitors, but not for other RAAS blockers, is an increase in bradykinin level. A persistent dry cough is a relatively common adverse effect believed to be associated with the increases in bradykinin levels produced by ACE inhibitors, although the role of bradykinin in producing these symptoms has been disputed. Many cases of cough in people on ACE inhibitors may not be from the medication itself, however. People who experience this cough are often switched to angiotensin II receptor antagonists. Some (0.7%) develop angioedema due to increased bradykinin levels. A genetic predisposition may exist. A severe rare allergic reaction can affect the bowel wall and secondarily cause abdominal pain. Blood Hematologic effects, such as neutropenia, agranulocytosis and other blood dyscrasias, have occurred during therapy with ACE inhibitors, especially in people with additional risk factors. Pregnancy In pregnant women, ACE inhibitors taken during all the trimesters have been reported to cause congenital malformations, stillbirths, and neonatal deaths. Commonly reported fetal abnormalities include hypotension, renal dysplasia, anuria/oliguria, oligohydramnios, intrauterine growth retardation, pulmonary hypoplasia, patent ductus arteriosus, and incomplete ossification of the skull. Overall, about half of newborns exposed to ACE inhibitors are adversely affected, leading to birth defects. ACE inhibitors are ADEC pregnancy category D and should be avoided in women who are likely to become pregnant. In the U.S., ACE inhibitors must be labeled with a boxed warning concerning the risk of birth defects when taken during the second and third trimester. Their use in the first trimester is also associated with a risk of major congenital malformations, particularly affecting the cardiovascular and central nervous systems. Overdose Symptoms and Treatment: There are few reports of ACE inhibitor overdose in the literature. The most likely manifestations are hypotension, which may be severe, hyperkalemia, hyponatremia and renal impairment with metabolic acidosis. Treatment should be mainly symptomatic and supportive, with volume expansion using normal saline to correct hypotension and improve renal function, and gastric lavage followed by activated charcoal and a cathartic to prevent further absorption of the drug. Captopril, enalapril, lisinopril and perindopril are known to be removable by hemodialysis. Contraindications and precautions The ACE inhibitors are contraindicated in people with: Pregnancy or breastfeeding Previous angioedema associated with ACE inhibitor therapy Bilateral renal artery stenosis Hypersensitivity to ACE inhibitors ACE inhibitors should be used with caution in people with: Impaired renal function Aortic valve stenosis or cardiac outflow obstruction Hypovolemia or dehydration Hemodialysis with high-flux polyacrylonitrile membranes A combination of ACE inhibitor with other drugs may increase effects of these drugs, but also the risk of adverse effects. The commonly reported adverse effects of drug combination with ACE are acute renal failure, hypotension, and hyperkalemia. The drugs interacting with ACE inhibitor should be prescribed with caution. Special attention should be given to combinations of ACE inhibitor with other RAAS blockers, diuretics (especially potassium-sparing diuretics), NSAIDs, anticoagulants, cyclosporine, DPP-4 inhibitors, and potassium supplements. Potassium supplementation should be used with caution and under medical supervision owing to the hyperkalemic effect of ACE inhibitors. Concomitant use with cyclooxygenase inhibitors tends to decrease ACE inhibitor's hypotensive effect. Mechanism of action ACE inhibitors reduce the activity of the renin–angiotensin–aldosterone system (RAAS) as the primary etiologic (causal) event in the development of hypertension in people with diabetes mellitus, as part of the insulin-resistance syndrome or as a manifestation of renal disease. Renin–angiotensin–aldosterone system The renin–angiotensin–aldosterone system is a major blood pressure regulating mechanism. Markers of electrolyte and water imbalance in the body such as hypotension, low distal tubule sodium concentration, decreased blood volume and high sympathetic tone trigger the release of the enzyme renin from the cells of juxtaglomerular apparatus in the kidney. Renin activates a circulating liver derived prohormone angiotensinogen by proteolytic cleavage of all but its first ten amino acid residues known as angiotensin I. ACE (angiotensin converting enzyme) then removes a further two residues, converting angiotensin I into angiotensin II. ACE is found in the pulmonary circulation and in the endothelium of many blood vessels. The system increases blood pressure by increasing the amount of salt and water the body retains, although angiotensin is also very good at causing the blood vessels to tighten (a potent vasoconstrictor). Effects ACE inhibitors block the conversion of angiotensin I (ATI) to angiotensin II (ATII). They thereby lower arteriolar resistance and increase venous capacity; decrease cardiac output, cardiac index, stroke work, and volume; lower resistance in blood vessels in the kidneys; and lead to increased natriuresis (excretion of sodium in the urine). Renin increases in concentration in the blood as a result of negative feedback of conversion of ATI to ATII. ATI increases for the same reason; ATII and aldosterone decrease. Bradykinin increases because of less inactivation by ACE. Under normal conditions, angiotensin II has these effects: Vasoconstriction (narrowing of blood vessels) and vascular smooth muscle hypertrophy (enlargement) induced by ATII may lead to increased blood pressure and hypertension. Further, constriction of the efferent arterioles of the kidney leads to increased perfusion pressure in the glomeruli. It contributes to ventricular remodeling and ventricular hypertrophy of the heart through stimulation of the proto-oncogenes c-fos, c-jun, c-myc, transforming growth factor beta (TGF-B), through fibrogenesis and apoptosis (programmed cell death). Stimulation by ATII of the adrenal cortex to release aldosterone, a hormone that acts on kidney tubules, causes sodium and chloride ions retention and potassium excretion. Sodium is a "water-holding" ion, so water is also retained, which leads to increased blood volume, hence an increase in blood pressure. Stimulation of the posterior pituitary to release vasopressin (antidiuretic hormone, ADH) also acts on the kidneys to increase water retention. If ADH production is excessive in heart failure, Na+ level in the plasma may fall (hyponatremia), and this is a sign of increased risk of death in heart failure patients. A decrease renal protein kinase C During the course of ACE inhibitor use, the production of ATII is decreased, which prevents aldosterone release from the adrenal cortex. This allows the kidney to excrete sodium ions along with obligate water, and retain potassium ions. This decreases blood volume, leading to decreased blood pressure. Epidemiological and clinical studies have shown ACE inhibitors reduce the progress of diabetic nephropathy independently from their blood pressure-lowering effect. This action of ACE inhibitors is used in the prevention of diabetic renal failure. ACE inhibitors have been shown to be effective for indications other than hypertension even in patients with normal blood pressure. The use of a maximum dose of ACE inhibitors in such patients (including for prevention of diabetic nephropathy, congestive heart failure, and prophylaxis of cardiovascular events) is justified, because it improves clinical outcomes independently of the blood pressure-lowering effect of ACE inhibitors. Such therapy, of course, requires careful and gradual titration of the dose to prevent the effects of rapidly decreasing blood pressure (dizziness, fainting, etc.). ACE inhibitors have also been shown to cause a central enhancement of parasympathetic nervous system activity in healthy volunteers and patients with heart failure. This action may reduce the prevalence of malignant cardiac arrhythmias, and the reduction in sudden death reported in large clinical trials. ACE Inhibitors also reduce plasma norepinephrine levels, and its resulting vasoconstriction effects, in heart failure patients, thus breaking the vicious circles of sympathetic and renin angiotensin system activation, which sustains the downward spiral in cardiac function in congestive heart failure The ACE inhibitor enalapril has also been shown to reduce cardiac cachexia in patients with chronic heart failure. Cachexia is a poor prognostic sign in patients with chronic heart failure. ACE inhibitors are under early investigation for the treatment of frailty and muscle wasting (sarcopenia) in elderly patients without heart failure. Examples ACE inhibitors are easily identifiable by their common suffix, '-pril'. ACE inhibitors can be divided into three groups based on their molecular structure of the enzyme binding sites (sulfhydryl, phosphinyl, carboxyl) to the active center of ACE: Sulfhydryl-containing agents Alacepril Captopril (trade name Capoten), the first ACE inhibitor. Zofenopril These agents appear to show antioxidative properties but may be involved in adverse events such as skin eruptions. Dicarboxylate-containing agents This is the largest group, including: Enalapril (Vasotec/Renitec/Berlipril/Enap/Enalapril Profarma) Ramipril (Altace/Prilace/Ramace/Ramiwin/Triatec/Tritace/Ramitac) Quinapril (Accupril) Perindopril (Coversyl/Aceon/Perindo) Lisinopril (Listril/Lopril/Novatec/Prinivil/Zestril, Lisidigal) Benazepril (Lotensin) Imidapril (Tanatril) Trandolapril (Mavik/Odrik/Gopten) Cilazapril (Inhibace) Phosphonate-containing agents Fosinopril (Fositen/Monopril) is the only member of this group Naturally occurring A comprehensive resource on anti-hypertensive peptides is available in form of a database. It contains around 1700 unique antihypertensive peptides Arfalasin (HOE 409) is angiotensin antagonist. Dairy products Casokinins and lactokinins, breakdown products of casein and whey, occur naturally after ingestion of milk products, especially cultured milk. Their role in blood pressure control is uncertain. The lactotripeptides Val-Pro-Pro and Ile-Pro-Pro produced by the probiotic Lactobacillus helveticus or derived from casein have been shown to have ACE-inhibiting and antihypertensive functions. In one study, L. helveticus PR4 was isolated from Italian cheeses. Comparative information All ACE inhibitors have similar antihypertensive efficacy when equivalent doses are administered. The main differences lie with captopril, the first ACE inhibitor. Captopril has a shorter duration of action and an increased incidence of adverse effects. It is also the only ACE inhibitor capable of passing through the blood–brain barrier, although the significance of this characteristic has not been shown to have any positive clinical effects. In a large clinical study, one of the agents in the ACE inhibitor class, ramipril (Altace), demonstrated an ability to reduce the mortality rates of patients suffering from a myocardial infarction and to slow the subsequent development of heart failure. This finding was made after it was discovered that regular use of ramipril reduced mortality rates even in test subjects not having suffered from hypertension. Some believe ramipril's additional benefits may be shared by some or all drugs in the ACE-inhibitor class. However, ramipril currently remains the only ACE inhibitor for which such effects are actually evidence-based. A meta-analysis confirmed that ACE inhibitors are effective and certainly the first-line choice in hypertension treatment. This meta-analysis was based on 20 trials and a cohort of 158,998 patients, of whom 91% were hypertensive. ACE inhibitors were used as the active treatment in seven trials (n=76,615) and angiotensin receptor blocker (ARB) in 13 trials (n=82,383). ACE inhibitors were associated with a statistically significant 10% mortality reduction: (HR 0.90; 95% CI, 0.84–0.97; P=0.004). In contrast, no significant mortality reduction was observed with ARB treatment (HR 0.99; 95% CI, 0.94–1.04; P=0.683). Analysis of mortality reduction by different ACE inhibitors showed that perindopril-based regimens are associated with a statistically significant 13% all-cause mortality reduction. Taking into account the broad spectrum of the hypertensive population, one might expect that an effective treatment with ACE inhibitors, in particular with perindopril, would result in an important gain of lives saved. Equivalent doses in hypertension The ACE inhibitors have different strengths with different starting dosages. Dosage should be adjusted according to the clinical response. Angiotensin II receptor antagonists ACE inhibitors possess many common characteristics with another class of cardiovascular drugs, angiotensin II receptor antagonists, which are often used when patients are intolerant of the adverse effects produced by ACE inhibitors. ACE inhibitors do not completely prevent the formation of angiotensin II, as blockage is dose-dependent, so angiotensin II receptor antagonists may be useful because they act to prevent the action of angiotensin II at the AT1 receptor, leaving AT2 receptor unblocked; the latter may have consequences needing further study. Use in combination The combination therapy of angiotensin II receptor antagonists with ACE inhibitors may be superior to either agent alone. This combination may increase levels of bradykinin while blocking the generation of angiotensin II and its activity at the AT1 receptor. This 'dual blockade' may be more effective than using an ACE inhibitor alone, because angiotensin II can be generated via non-ACE-dependent pathways. Preliminary studies suggest this combination of pharmacologic agents may be advantageous in the treatment of essential hypertension, chronic heart failure, and nephropathy. However, the more recent ONTARGET study showed no benefit of combining the agents and more adverse events. While statistically significant results have been obtained for its role in treating hypertension, clinical significance may be lacking. There are warnings about the combination of ACE inhibitors with ARBs. Patients with heart failure may benefit from the combination in terms of reducing morbidity and ventricular remodeling. The most compelling evidence for the treatment of nephropathy has been found: This combination therapy partially reversed the proteinuria and also exhibited a renoprotective effect in patients afflicted with diabetic nephropathy, and pediatric IgA nephropathy. History Leonard T. Skeggs and his colleagues (including Norman Shumway) discovered ACE in plasma in 1956. It was also noted that those who worked in banana plantations in South-western Brazil collapsed after being bitten by a pit viper, leading to a search for a blood pressure lowering component in its venom. Brazilian scientist Sérgio Henrique Ferreira reported a bradykinin-potentiating factor (BPF) present in the venom of Bothrops jararaca, a South American pit viper, in 1965. Ferreira then went to John Vane's laboratory as a postdoctoral fellow with his already-isolated BPF. The conversion of the inactive angiotensin I to the potent angiotensin II was thought to take place in the plasma. However, in 1967, Kevin K. F. Ng and John R. Vane showed plasma ACE is too slow to account for the conversion of angiotensin I to angiotensin II in vivo. Subsequent investigation showed rapid conversion occurs during its passage through the pulmonary circulation. Bradykinin is rapidly inactivated in the circulating blood, and it disappears completely in a single pass through the pulmonary circulation. Angiotensin I also disappears in the pulmonary circulation because of its conversion to angiotensin II. Furthermore, angiotensin II passes through the lungs without any loss. The inactivation of bradykinin and the conversion of angiotensin I to angiotensin II in the lungs was thought to be caused by the same enzyme. In 1970, Ng and Vane, using BPF provided by Ferreira, showed the conversion is inhibited during its passage through the pulmonary circulation. BPFs are members of a family of peptides whose potentiating action is linked to inhibition of bradykinin by ACE. Molecular analysis of BPF yielded a nonapeptide BPF teprotide (SQ 20,881), which showed the greatest ACE inhibition potency and hypotensive effect in vivo. Teprotide had limited clinical value as a result of its peptide nature and lack of activity when given orally. In the early 1970s, knowledge of the structure-activity relationship required for inhibition of ACE was growing. David Cushman, Miguel Ondetti and colleagues used peptide analogues to study the structure of ACE, using carboxypeptidase A as a model. Their discoveries led to the development of captopril, the first orally-active ACE inhibitor, in 1975. Captopril was approved by the United States Food and Drug Administration in 1981. The first nonsulfhydryl-containing ACE inhibitor, enalapril, was marketed two years later. At least 12 other ACE inhibitors have since been marketed. In 1991, Japanese scientists created the first milk-based ACE inhibitor, in the form of a fermented milk drink, using specific cultures to liberate the tripeptide isoleucine-proline-proline (IPP) from the dairy protein. Valine-proline-proline (VPP) is also liberated in this process—another milk tripeptide with a very similar chemical structure to IPP. Together, these peptides are now often referred to as lactotripeptides. In 1996, the first human study confirmed the blood pressure-lowering effect of IPP in fermented milk. Although twice the amount of VPP is needed to achieve the same ACE-inhibiting activity as the originally discovered IPP, VPP also is assumed to add to the total blood pressure lowering effect. Since the first lactotripeptides discovery, more than 20 human clinical trials have been conducted in many different countries.

The Antigonid dynasty (; ) was a Hellenistic dynasty of Dorian Greek provenance, descended from Alexander the Great's general Antigonus I Monophthalmus ("the One-Eyed") that ruled mainly in Macedonia. History Succeeding the Antipatrid dynasty in much of Macedonia, Antigonus ruled mostly over Asia Minor and northern Syria. His attempts to take control of the whole of Alexander's empire led to his defeat and death at the Battle of Ipsus in 301 BC. Antigonus's son Demetrius I Poliorcetes survived the battle, and managed to seize control of Macedon itself a few years later, but eventually lost his throne, dying as a prisoner of Seleucus I Nicator. After a period of confusion, Demetrius's son Antigonus II Gonatas was able to establish the family's control over the old Kingdom of Macedon, as well as over most of the Greek city-states, by 276 BC. Legacy It was one of four dynasties established by Alexander's successors, the others being the Seleucid dynasty, Ptolemaic dynasty and Attalid dynasty. The last scion of the dynasty, Perseus of Macedon, who reigned between 179 and 168 BC, proved unable to stop the advancing Roman legions and Macedon's defeat at the Battle of Pydna signaled the end of the dynasty. Dynasty The ruling members of the Antigonid dynasty were: The Greek rebel against Rome and last King of Macedonia, Andriscus, claimed to be the son of Perseus.

Amoxicillin is an antibiotic used to treat a number of bacterial infections. These include middle ear infection, strep throat, pneumonia, skin infections, and urinary tract infections among others. It is taken by mouth, or less commonly by injection. Common adverse effects include nausea and rash. It may also increase the risk of yeast infections and, when used in combination with clavulanic acid, diarrhea. It should not be used in those who are allergic to penicillin. While usable in those with kidney problems, the dose may need to be decreased. Its use in pregnancy and breastfeeding does not appear to be harmful. Amoxicillin is in the beta-lactam family of antibiotics. Amoxicillin was discovered in 1958 and came into medical use in 1972. It is on the World Health Organization's List of Essential Medicines. It is one of the most commonly prescribed antibiotics in children. Amoxicillin is available as a generic medication. In 2019, it was the 23rd most commonly prescribed medication in the United States, with more than 25million prescriptions. Medical uses Amoxicillin is used in the treatment of a number of infections, including acute otitis media, streptococcal pharyngitis, pneumonia, skin infections, urinary tract infections, Salmonella infections, Lyme disease, and chlamydia infections. Acute otitis media Children with acute otitis media who are younger than 6 months of age are generally treated with amoxicillin or other antibiotics. Although most children with acute otitis media who are older than two years old do not benefit from treatment with amoxicillin or other antibiotics, such treatment may be helpful in children younger than two years old with acute otitis media that is bilateral or accompanied by ear drainage. In the past, amoxicillin was dosed three times daily when used to treat acute otitis media, which resulted in missed doses in routine ambulatory practice. There is now evidence that two times daily dosing or once daily dosing has similar effectiveness. Respiratory infections Amoxicillin and amoxicillin-clavulanate have been recommended by guidelines as the drug of choice for bacterial sinusitis and other respiratory infections. Most sinusitis infections are caused by viruses, for which amoxicillin and amoxicillin-clavulanate are ineffective, and the small benefit gained by amoxicillin may be overridden by the adverse effects. Amoxicillin is recommended as the preferred first-line treatment for community-acquired pneumonia in adults by the National Institute for Health and Care Excellence, either alone (mild to moderate severity disease) or in combination with a macrolide. The World Health Organization (WHO) recommends amoxicillin as first-line treatment for pneumonia that is not "severe". Amoxicillin is used in post-exposure inhalation of anthrax to prevent disease progression and for prophylaxis. H. pylori It is effective as one part of a multi-drug regimen for treatment of stomach infections of Helicobacter pylori. It is typically combined with a proton-pump inhibitor (such as omeprazole) and a macrolide antibiotic (such as clarithromycin); other drug combinations are also effective. Lyme borreliosis Amoxicillin is effective for treatment of early cutaneous Lyme borreliosis; the effectiveness and safety of oral amoxicillin is neither better nor worse than common alternatively-used antibiotics. Skin infections Amoxicillin is occasionally used for the treatment of skin infections, such as acne vulgaris. It is often an effective treatment for cases of acne vulgaris that have responded poorly to other antibiotics, such as doxycycline and minocycline. Infections in infants in resource-limited settings Amoxicillin is recommended by the World Health Organization for the treatment of infants with signs and symptoms of pneumonia in resource-limited situations when the parents are unable or unwilling to accept hospitalization of the child. Amoxicillin in combination with gentamicin is recommended for the treatment of infants with signs of other severe infections when hospitalization is not an option. Prevention of bacterial endocarditis It is also used to prevent bacterial endocarditis and as a pain-reliever in high-risk people having dental work done, to prevent Streptococcus pneumoniae and other encapsulated bacterial infections in those without spleens, such as people with sickle-cell disease, and for both the prevention and the treatment of anthrax. The United Kingdom recommends against its use for infectious endocarditis prophylaxis. These recommendations do not appear to have changed the rates of infection for infectious endocarditis. Combination treatment Amoxicillin is susceptible to degradation by β-lactamase-producing bacteria, which are resistant to most β-lactam antibiotics, such as penicillin. For this reason, it may be combined with clavulanic acid, a β-lactamase inhibitor. This drug combination is commonly called co-amoxiclav. Spectrum of activity It is a moderate-spectrum, bacteriolytic, β-lactam antibiotic in the aminopenicillin family used to treat susceptible Gram-positive and Gram-negative bacteria. It is usually the drug of choice within the class because it is better-absorbed, following oral administration, than other β-lactam antibiotics. In general, Streptococcus, Bacillus subtilis, Enterococcus, Haemophilus, Helicobacter, and Moraxella are susceptible to amoxicillin, whereas Citrobacter, Klebsiella and Pseudomonas aeruginosa are resistant to it. Some E. coli and most clinical strains of Staphylococcus aureus have developed resistance to amoxicillin to varying degrees. Adverse effects Adverse effects are similar to those for other β-lactam antibiotics, including nausea, vomiting, rashes, and antibiotic-associated colitis. Loose bowel movements (diarrhea) may also occur. Rarer adverse effects include mental changes, lightheadedness, insomnia, confusion, anxiety, sensitivity to lights and sounds, and unclear thinking. Immediate medical care is required upon the first signs of these adverse effects. The onset of an allergic reaction to amoxicillin can be very sudden and intense; emergency medical attention must be sought as quickly as possible. The initial phase of such a reaction often starts with a change in mental state, skin rash with intense itching (often beginning in fingertips and around groin area and rapidly spreading), and sensations of fever, nausea, and vomiting. Any other symptoms that seem even remotely suspicious must be taken very seriously. However, more mild allergy symptoms, such as a rash, can occur at any time during treatment, even up to a week after treatment has ceased. For some people allergic to amoxicillin, the adverse effects can be fatal due to anaphylaxis. Use of the amoxicillin/clavulanic acid combination for more than one week has caused a drug-induced immunoallergic-type hepatitis in some patients. Young children having ingested acute overdoses of amoxicillin manifested lethargy, vomiting, and renal dysfunction. There is poor reporting of adverse effects of amoxicillin from clinical trials. For this reason, the severity and frequency of adverse effects from amoxicillin is probably higher than reported from clinical trials. Nonallergic rash Between 3 and 10% of children taking amoxicillin (or ampicillin) show a late-developing (>72 hours after beginning medication and having never taken penicillin-like medication previously) rash, which is sometimes referred to as the "amoxicillin rash". The rash can also occur in adults and may rarely be a component of the DRESS syndrome. The rash is described as maculopapular or morbilliform (measles-like; therefore, in medical literature, it is called "amoxicillin-induced morbilliform rash".). It starts on the trunk and can spread from there. This rash is unlikely to be a true allergic reaction and is not a contraindication for future amoxicillin usage, nor should the current regimen necessarily be stopped. However, this common amoxicillin rash and a dangerous allergic reaction cannot easily be distinguished by inexperienced persons, so a healthcare professional is often required to distinguish between the two. A nonallergic amoxicillin rash may also be an indicator of infectious mononucleosis. Some studies indicate about 80-90% of patients with acute Epstein Barr virus infection treated with amoxicillin or ampicillin develop such a rash. Interactions Amoxicillin may interact with these drugs: Anticoagulants (dabigatran, warfarin). Cancer treatment (methotrexate). Uricosuric drugs. Typhoid vaccine Probenecid reduces renal excretion and increases the blood levels of amoxicillin. Oral contraceptives may become less effective. Allopurinol (gout treatment). Pharmacology Amoxicillin (α-amino-p-hydroxybenzyl penicillin) is a semisynthetic derivative of penicillin with a structure similar to ampicillin but with better absorption when taken by mouth, thus yielding higher concentrations in blood and in urine. Amoxicillin diffuses easily into tissues and body fluids. It will cross the placenta and is excreted into breastmilk in small quantities. It is metabolized by the liver and excreted into the urine. It has an onset of 30 minutes and a half-life of 3.7 hours in newborns and 1.4 hours in adults. Amoxicillin attaches to the cell wall of susceptible bacteria and results in their death. It also is a bactericidal compound. It is effective against streptococci, pneumococci, enterococci, Haemophilus influenzae, Escherichia coli, Proteus mirabilis, Neisseria meningitidis, Neisseria gonorrhoeae, Shigella, Chlamydia trachomatis, Salmonella, Borrelia burgdorferi, and Helicobacter pylori. As a derivative of ampicillin, amoxicillin is a member of the penicillin family and, like penicillins, is a β-lactam antibiotic. It inhibits cross-linkage between the linear peptidoglycan polymer chains that make up a major component of the bacterial cell wall. It has two ionizable groups in the physiological range (the amino group in alpha-position to the amide carbonyl group and the carboxyl group). History Amoxicillin was one of several semisynthetic derivatives of 6-aminopenicillanic acid (6-APA) developed by the Beecham Group in the 1960s. It became available in 1972 and was the second aminopenicillin to reach the market (after ampicillin in 1961). Co-amoxiclav became available in 1981. Society and culture Cost Amoxicillin is relatively inexpensive. Modes of delivery Pharmaceutical manufacturers make amoxicillin in trihydrate form, for oral use available as capsules, regular, chewable and dispersible tablets, syrup and pediatric suspension for oral use, and as the sodium salt for intravenous administration. Amoxicillin is most commonly taken orally. The liquid forms are helpful where the patient might find it difficult to take tablets or capsules. An extended-release is available. The intravenous form of amoxicillin is not sold in the United States. When an intravenous aminopenicillin is required in the United States, ampicillin is typically used. When there is an adequate response to ampicillin, the course of antibiotic therapy may often be completed with oral amoxicillin. Research with mice indicated successful delivery using intraperitoneally injected amoxicillin-bearing microparticles. Names "Amoxicillin" is the International Nonproprietary Name (INN), British Approved Name (BAN), and United States Adopted Name (USAN), while "amoxycillin" is the Australian Approved Name (AAN). Amoxicillin is one of the semisynthetic penicillins discovered by Beecham scientists. The patent for amoxicillin has expired, thus amoxicillin and co-amoxiclav preparations are marketed under various trade names across the world. Other animals Amoxicillin is also sometimes used as an antibiotic for animals. The use of amoxicillin for animals intended for human consumption (chickens, cattle, and swine for example) has been approved.

Ariel Sharon (; ; ; also known by his diminutive Arik, , born Ariel Scheinermann, ; 26 February 1928 – 11 January 2014) was an Israeli general and politician who served as the 11th Prime Minister of Israel from March 2001 until April 2006. Sharon was a commander in the Israeli Army from its creation in 1948. As a soldier and then an officer, he participated prominently in the 1948 Palestine war, becoming a platoon commander in the Alexandroni Brigade and taking part in many battles, including Operation Bin Nun Alef. He was an instrumental figure in the creation of Unit 101 and the reprisal operations, as well as in the 1956 Suez Crisis, the Six-Day War of 1967, the War of Attrition, and the Yom-Kippur War of 1973. Yitzhak Rabin called Sharon "the greatest field commander in our history". Upon retirement from the military, Sharon entered politics, joining the Likud party, and served in a number of ministerial posts in Likud-led governments in 1977–92 and 1996–99. As Minister of Defense, he directed the 1982 Lebanon War. An official enquiry found that he bore "personal responsibility" for the Sabra and Shatila massacre and recommended that he be removed as Defense Minister. His perceived complicity in the massacre led to him being known as the "Butcher of Beirut" among Arabs. From the 1970s through to the 1990s, Sharon championed construction of Israeli settlements in the West Bank and Gaza Strip. He became the leader of the Likud in 2000, and was elected Prime Minister of Israel after defeating Ehud Barak in the 2001 prime ministerial election. He served as Israel's prime minister from 2001 to 2006, during the Al-Aqsa Intifada. As Prime Minister, Sharon orchestrated Israel's unilateral disengagement from the Gaza Strip in 2004–05. Facing stiff opposition to this policy within the Likud, in November 2005 he left Likud to form a new party, Kadima. He had been expected to win the next election and was widely interpreted as planning on "clearing Israel out of most of the West Bank", in a series of unilateral withdrawals. After suffering a stroke on 4 January 2006, Sharon remained in a permanent vegetative state until his death in January 2014. Sharon remains a highly polarizing figure in Middle East history. Israelis almost universally revere Sharon as a war hero and statesman who played a vital role in defining the country's borders, while Palestinians revile Sharon as an impenitent war criminal who vigorously suppressed their aspirations for nationhood. Early life and education Sharon was born on 26 February 1928 in Kfar Malal, an agricultural moshav, then in Mandatory Palestine, to Shmuel Scheinerman (1896–1956) of Brest-Litovsk and Vera (née Schneirov) Scheinerman (1900–1988) of Mogilev. His parents met while at university in Tiflis (now Tbilisi, Republic of Georgia), where Sharon's father was studying agronomy and his mother was studying medicine. They immigrated to Mandatory Palestine in 1922 in the wake of the Russian Communist government's growing persecution of Jews in the region. In Palestine, Vera Scheinerman went by the name Dvora. The family arrived with the Third Aliyah and settled in Kfar Malal, a socialist, secular community. (Ariel Sharon himself would remain proudly secular throughout his life.) Although his parents were Mapai supporters, they did not always accept communal consensus: "The Scheinermans' eventual ostracism ... followed the 1933 Arlozorov murder when Dvora and Shmuel refused to endorse the Labor movement's anti-Revisionist calumny and participate in Bolshevik-style public revilement rallies, then the order of the day. Retribution was quick to come. They were expelled from the local health-fund clinic and village synagogue. The cooperative's truck wouldn't make deliveries to their farm nor collect produce." Sharon spoke both Hebrew and Russian. Four years after their arrival at Kfar Malal, the Sheinermans had a daughter, Yehudit (Dita). Ariel was born two years later. At age 10, he joined the youth movement HaNoar HaOved VeHaLomed. As a teenager, he began to take part in the armed night-patrols of his moshav. In 1942 at the age of 14, Sharon joined the Gadna, a paramilitary youth battalion, and later the Haganah, the underground paramilitary force and the Jewish military precursor to the Israel Defense Forces (IDF). Military career Battle for Jerusalem and 1948 War Sharon's unit of the Haganah became engaged in serious and continuous combat from the autumn of 1947, with the onset of the Battle for Jerusalem. Without the manpower to hold the roads, his unit took to making offensive hit-and-run raids on Arab forces in the vicinity of Kfar Malal. In units of thirty men, they would hit constantly at Arab villages, bridges and bases, as well as ambush the traffic between Arab villages and bases. Sharon wrote in his autobiography: "We had become skilled at finding our way in the darkest nights and gradually we built up the strength and endurance these kind of operations required. Under the stress of constant combat we drew closer to one another and began to operate not just as a military unit but almost as a family. ... [W]e were in combat almost every day. Ambushes and battles followed each other until they all seemed to run together." For his role in a night-raid on Iraqi forces at Bir Adas, Sharon was made a platoon commander in the Alexandroni Brigade. Following the Israeli Declaration of Independence and the onset of the War of Independence, his platoon fended off the Iraqi advance at Kalkiya. Sharon was regarded as a hardened and aggressive soldier, swiftly moving up the ranks during the war. He was shot in the groin, stomach and foot by the Jordanian Arab Legion in the First Battle of Latrun, an unsuccessful attempt to relieve the besieged Jewish community of Jerusalem. Sharon wrote of the casualties in the "horrible battle," and his brigade suffered 139 deaths. Jordanian field marshal Habis Al-Majali claimed that Sharon was among 6 Israeli soldiers captured by the Jordanian 4th battalion during the battle, and that Habis took them to a camp in Mafraq and the 6 were later traded back. Sharon denied the claims, but Habes was adamant. "Sharon is like a grizzly bear," he grumbled. "I captured him, I healed his wounds." In 1994 and during the peace treaty signing ceremony with Jordan, Sharon wanted to get in touch with his former captor, but the latter determinedly refused to discuss the incident publicly. After recovering from the wounds received at Latrun, he resumed command of his patrol unit. On 28 December 1948, his platoon attempted to break through an Egyptian stronghold in Iraq-El-Manshia. At about this time, Israeli founding father David Ben-Gurion gave him the Hebraized name "Sharon". In September 1949, Sharon was promoted to company commander (of the Golani Brigade's reconnaissance unit) and in 1950 to intelligence officer for Central Command. He then took leave to begin studies in history and Middle Eastern culture at the Hebrew University of Jerusalem. Sharon's subsequent military career would be characterized by insubordination, aggression and disobedience, but also brilliance as a commander. Unit 101 A year and a half later, on the direct orders of the Prime Minister, Sharon returned to active service in the rank of major, as the founder and commander of the new Unit 101, a special forces unit tasked with reprisal operations in response to Palestinian fedayeen attacks. The first Israeli commando unit, Unit 101 specialized in offensive guerrilla warfare in enemy countries. The unit consisted of 50 men, mostly former paratroopers and Unit 30 personnel. They were armed with non-standard weapons and tasked with carrying out special reprisals across the state's borders— mainly establishing small unit maneuvers, activation and insertion tactics. Training included engaging enemy forces across Israel's borders. Israeli historian Benny Morris describes Unit 101: Unit 101 undertook a series of raids against Jordan, which then held the West Bank. The raids also helped bolster Israeli morale and convince Arab states that the fledgling nation was capable of long-range military action. Known for raids against Arab civilians and military targets, the unit is held responsible for the widely condemned Qibya massacre in the fall of 1953. After a group of Palestinians used Qibya as a staging point for a fedayeen attack in Yehud that killed a Jewish woman and her two children in Israel, Unit 101 retaliated on the village. By various accounts of the ensuing attack, 65 to 70 Palestinian civilians, half of them women and children, were killed when Sharon's troops dynamited 45 houses and a school. Facing international condemnation for the attack, Ben-Gurion denied that the Israeli military was involved. In his memoir, Sharon wrote that the unit had checked all the houses before detonating the explosives and that he thought the houses were empty. Although he admitted the results were tragic, Sharon defended the attack, however: "Now people could feel that the terrorist gangs would think twice before striking, now that they knew for sure they would be hit back. Kibbya also put the Jordanian and Egyptian governments on notice that if Israel was vulnerable, so were they." A few months after its founding, Unit 101 was merged with the 890 Paratroopers Battalion to create the Paratroopers Brigade, of which Sharon would also later become commander. Like Unit 101, it continued raids into Arab territory, culminating with the attack on the Qalqilyah police station in the autumn of 1956. Leading up to the Suez War, the missions Sharon took part in included: Operation Shoshana (now known as the Qibya massacre) Operation Black Arrow Operation Elkayam Operation Egged Operation Olive Leaves Operation Volcano Operation Gulliver (מבצע גוליבר) Operation Lulav (מבצע לולב) During a payback operation in the Deir al-Balah refugee camp in the Gaza Strip, Sharon was again wounded by gunfire, this time in the leg. Incidents such as those involving Meir Har-Zion, along with many others, contributed to the tension between Prime Minister Moshe Sharett, who often opposed Sharon's raids, and Moshe Dayan, who had become increasingly ambivalent in his feelings towards Sharon. Later in the year, Sharon was investigated and tried by the Military Police for disciplining one of his subordinates. However, the charges were dismissed before the onset of the Suez War. 1956 Suez War Sharon commanded Unit 202 (the Paratroopers Brigade) during the 1956 Suez War (the British "Operation Musketeer"), leading the troop to take the ground east of the Sinai's Mitla Pass and eventually the pass itself against the advice of superiors, suffering heavy Israeli casualties in the process. Having successfully carried out the first part of his mission (joining a battalion parachuted near Mitla with the rest of the brigade moving on ground), Sharon's unit was deployed near the pass. Neither reconnaissance aircraft nor scouts reported enemy forces inside the Mitla Pass. Sharon, whose forces were initially heading east, away from the pass, reported to his superiors that he was increasingly concerned with the possibility of an enemy thrust through the pass, which could attack his brigade from the flank or the rear. Sharon asked for permission to attack the pass several times, but his requests were denied, though he was allowed to check its status so that if the pass was empty, he could receive permission to take it later. Sharon sent a small scout force, which was met with heavy fire and became bogged down due to vehicle malfunction in the middle of the pass. Sharon ordered the rest of his troops to attack in order to aid their comrades. Sharon was criticized by his superiors and was damaged by allegations several years later made by several former subordinates, who claimed that Sharon tried to provoke the Egyptians and sent out the scouts in bad faith, ensuring that a battle would ensue. Sharon had assaulted Themed in a dawn attack, and had stormed the town with his armor through the Themed Gap. Sharon routed the Sudanese police company, and captured the settlement. On his way to the Nakla, Sharon's men came under attack from Egyptian MIG-15s. On the 30th, Sharon linked up with Eytan near Nakla. Dayan had no more plans for further advances beyond the passes, but Sharon nonetheless decided to attack the Egyptian positions at Jebel Heitan. Sharon sent his lightly armed paratroopers against dug-in Egyptians supported by aircraft, tanks and heavy artillery. Sharon's actions were in response to reports of the arrival of the 1st and 2nd Brigades of the 4th Egyptian Armored Division in the area, which Sharon believed would annihilate his forces if he did not seize the high ground. Sharon sent two infantry companies, a mortar battery and some AMX-13 tanks under the command of Mordechai Gur into the Heitan Defile on the afternoon of 31 October 1956. The Egyptian forces occupied strong defensive positions and brought down heavy anti-tank, mortar and machine gun fire on the IDF force. Gur's men were forced to retreat into the "Saucer", where they were surrounded and came under heavy fire. Hearing of this, Sharon sent in another task force while Gur's men used the cover of night to scale the walls of the Heitan Defile. During the ensuing action, the Egyptians were defeated and forced to retreat. A total of 260 Egyptian and 38 Israeli soldiers were killed during the battle at Mitla. Due to these deaths, Sharon's actions at Mitla were surrounded in controversy, with many within the IDF viewing the deaths as the result of unnecessary and unauthorized aggression. Six-Day War, War of Attrition and Yom Kippur War The Mitla incident hindered Sharon's military career for several years. In the meantime, he occupied the position of an infantry brigade commander and received a law degree from Tel Aviv University. However, when Yitzhak Rabin became Chief of Staff in 1964, Sharon again began to rise rapidly in the ranks, occupying the positions of Infantry School Commander and Head of Army Training Branch, eventually achieving the rank of Aluf (Major General). In the Six-Day War, Sharon, in command of an armored division on the Sinai front, drew up his own complex offensive strategy that combined infantry troops, tanks and paratroopers from planes and helicopters to destroy the Egyptian forces Sharon's 38th Division faced when it broke through to the Kusseima-Abu-Ageila fortified area. Sharon's victories and offensive strategy in the Battle of Abu-Ageila led to international commendation by military strategists; he was judged to have inaugurated a new paradigm in operational command. Researchers at the United States Army Training and Doctrine Command studied Sharon's operational planning, concluding that it involved a number of unique innovations. It was a simultaneous attack by a multiplicity of small forces, each with a specific aim, attacking a particular unit in a synergistic Egyptian defense network. As a result, instead of supporting and covering each other as they were designed to do, each Egyptian unit was left fighting for its own life. According to Sapir Handelman, after Sharon's assault of the Sinai in the Six-Day War and his encirclement of the Egyptian Third Army in the Yom Kippur War, the Israeli public nicknamed him "The King of Israel". Sharon played a key role in the War of Attrition. In 1969, he was appointed the Head of IDF's Southern Command. As leader of the southern command, on 29 July Israeli frogmen stormed and destroyed Green Island, a fortress at the northern end of the Gulf of Suez whose radar and antiaircraft installations controlled that sector's airspace. On 9 September Sharon's forces carried out Operation Raviv, a large-scale raid along the western shore of the Gulf of Suez. Landing craft ferried across Russian-made tanks and armored personnel carriers that Israel had captured in 1967, and the small column harried the Egyptians for ten hours. Following his appointment to the southern command, Sharon had no further promotions, and considered retiring. Sharon discussed the issue with Rabbi Menachem M. Schneerson, who strongly advised him to remain at his post. Sharon remained in the military for another three years, before retiring in August 1973. Soon after, he helped found the Likud ("Unity") political party. At the start of the Yom Kippur War on 6 October 1973, Sharon was called back to active duty along with his assigned reserve armored division. On his farm, before he left for the front line, the Reserve Commander, Zeev Amit, said to him, "How are we going to get out of this?" Sharon replied, "You don't know? We will cross the Suez Canal and the war will end over there." Sharon arrived at the front, to participate in his fourth war, in a civilian car. His forces did not engage the Egyptian Army immediately, despite his requests. Under cover of darkness, Sharon's forces moved to a point on the Suez Canal that had been prepared before the war. In a move that again thwarted the commands of his superiors, Sharon's division crossed the Suez, effectively winning the war for Israel. He then headed north towards Ismailia, intent on cutting the Egyptian second army's supply lines, but his division was halted south of the Fresh Water Canal. Abraham Adan's division passed over the bridgehead into Africa, advancing to within 101 kilometers of Cairo. His division managed to encircle Suez, cutting off and encircling the Third Army. Tensions between the two generals followed Sharon's decision, but a military tribunal later found his action was militarily effective. Sharon's complex ground maneuver is regarded as a decisive move in the Yom Kippur War, undermining the Egyptian Second Army and encircling the Egyptian Third Army. This move was regarded by many Israelis as the turning point of the war in the Sinai front. Thus, Sharon is widely viewed as the hero of the Yom Kippur War, responsible for Israel's ground victory in the Sinai in 1973. A photo of Sharon wearing a head bandage on the Suez Canal became a famous symbol of Israeli military prowess. Sharon's political positions were controversial, and he was relieved of duty in February 1974. Bar Lev Line Following Israel's victory in the six-day war, the war of attrition at the Suez Canal began. The Egyptians began firing in provocation against the Israeli forces posted on the eastern part of the canal. Haim Bar Lev, Israel's chief of staff, suggested that Israel construct a border line to protect its southern border. A wall of sand and earth raised along almost the entire length of the Suez Canal would both allow observation of Egyptian forces and conceal the movements of Israeli troops on the eastern side. This line, named after the chief of staff Haim Bar Lev, became known as the Bar Lev Line. It included at least thirty strong points stretching over almost 200 kilometers. Bar Lev suggested that such a line would defend against any major Egyptian assault across the canal, and was expected to function as a "graveyard for Egyptian troops". Moshe Dayan described it as "one of the best anti-tank ditches in the world." Sharon, and Israel Tal on the other hand, vigorously opposed the line. Sharon said that it would pin down large military formations that would be sitting ducks for deadly artillery attacks, and cited the opinion of Rabbi Menachem M. Schneerson, who explained him "the great military disaster such a line could bring." Notwithstanding, it was completed in spring 1970. During the Yom Kippur War, Egyptian forces successfully breached the Bar Lev Line in less than two hours at a cost of more than a thousand dead and some 5,000 wounded. Sharon would later recall that what Schneerson had told him was a tragedy, "but unfortunately, that happened." Early political career, 1974–2001 Beginnings of political career In the 1940s and 1950s, Sharon seemed to be personally devoted to the ideals of Mapai, the predecessor of the modern Labor Party. However, after retiring from military service, he joined the Liberal Party and was instrumental in establishing Likud in July 1973 by a merger of Herut, the Liberal Party and independent elements. Sharon became chairman of the campaign staff for that year's elections, which were scheduled for November. Two and a half weeks after the start of the election campaign, the Yom Kippur War erupted and Sharon was called back to reserve service. On the heels of being hailed as a war hero for crossing the Suez in the 1973 war, Sharon won a seat to the Knesset in the elections that year, but resigned a year later. From June 1975 to March 1976, Sharon was a special aide to Prime Minister Yitzhak Rabin. He planned his return to politics for the 1977 elections; first, he tried to return to the Likud and replace Menachem Begin at the head of the party. He suggested to Simha Erlich, who headed the Liberal Party bloc in the Likud, that he was more able than Begin to win an election victory; he was rejected, however. He then tried to join the Labor Party and the centrist Democratic Movement for Change, but was rejected by those parties too. Only then did he form his own list, Shlomtzion, which won two Knesset seats in the subsequent elections. Immediately after the elections, he merged Shlomtzion with the Likud and became Minister of Agriculture. When Sharon joined Begin's government, he had relatively little political experience. During this period, Sharon supported the Gush Emunim settlements movement and was viewed as the patron of the settlers' movement. He used his position to encourage the establishment of a network of Israeli settlements in the occupied territories to prevent the possibility of Palestinian Arabs' return to these territories. Sharon doubled the number of Jewish settlements on the West Bank and Gaza Strip during his tenure. After the 1981 elections, Begin rewarded Sharon for his important contribution to Likud's narrow win, by appointing him Minister of Defense. Under Sharon, Israel continued to build upon the unprecedented coordination between the Israel Defense Forces and the South African Defence Force, with Israeli and South African generals giving each other unfettered access to each other's battlefields and military tactics, and Israel sharing with South Africa highly classified information about its missions, such as Operation Opera, which had previously only been reserved for the United States. In 1981, after visiting South African forces fighting in Namibia for 10 days, Sharon argued that South Africa needed more weapons to fight Soviet infiltration in the region. Sharon promised that the relationship between Israel and South Africa would continue to deepen as they work to "ensure the National Defense of both our countries". The collaboration in carrying out joint-nuclear tests, in planning counter-insurgency strategies in Namibia and in designing security fences helped to make Israel, South Africa's closest ally in this period. 1982 Lebanon War and Sabra and Shatila massacre As Defense Minister, Sharon launched an invasion of Lebanon called Operation Peace for Galilee, later known as the 1982 Lebanon War, following the shooting of Israel's ambassador in London, Shlomo Argov. Although this attempted assassination was in fact perpetrated by the Abu Nidal Organization, possibly with Syrian or Iraqi involvement, the Israeli government justified the invasion by citing 270 terrorist attacks by the Palestinian Liberation Organization (PLO) in Israel, the occupied territories, and the Jordanian and Lebanese border (in addition to 20 attacks on Israeli interests abroad). Sharon intended the operation to eradicate the PLO from its state within a state inside Lebanon, but the war is primarily remembered for the Sabra and Shatila massacre. In a three-day massacre between 16 and 18 September, between 460 and 3,500 civilians, mostly Palestinians and Lebanese Shiites, in the Sabra neighborhood and the adjacent Shatila refugee camp were killed by the Phalanges— Lebanese Maronite Christian militias. Shatila had previously been one of the PLO's three main training camps for foreign terrorists and the main training camp for European terrorists; the Israelis maintained that 2,000 to 3,000 terrorists remained in the camps, but were unwilling to risk the lives of more of their soldiers after the Lebanese army repeatedly refused to "clear them out." The killings followed years of sectarian civil war in Lebanon that left 95,000 dead. The Lebanese army's chief prosecutor investigated the killings and counted 460 dead, Israeli intelligence estimated 700–800 dead, and the Palestinian Red Crescent claimed 2,000 dead. 1,200 death certificates were issued to anyone who produced three witnesses claiming a family member disappeared during the time of the massacre. Nearly all of the victims were men. The Phalange militia went into the camps to clear out PLO fighters while Israeli forces surrounded the camps, blocking camp exits and providing logistical support. The killings led some to label Sharon "the Butcher of Beirut". An Associated Press report on 15 September 1982 stated, "Defence Minister Ariel Sharon, in a statement, tied the killing of the Phalangist leader Bachir Gemayel to the PLO, saying 'it symbolises the terrorist murderousness of the PLO terrorist organisations and their supporters'." Habib Chartouni, a Lebanese Christian from the Syrian Socialist National Party confessed to the murder of Gemayel, and no Palestinians were involved. Robert Maroun Hatem, Hobeika's bodyguard, stated in his book From Israel to Damascus that Phalangist commander Elie Hobeika ordered the massacre of civilians in defiance of Israeli instructions to behave like a "dignified" army. Hatem claimed "Sharon had given strict orders to Hobeika....to guard against any desperate move" and that Hobeika perpetrated the massacre "to tarnish Israel's reputation worldwide" for the benefit of Syria. Hobeika subsequently joined the Syrian occupation government and lived as a prosperous businessman under Syrian protection; further massacres in Sabra and Shatilla occurred with Syrian support in 1985. The massacre followed intense Israeli bombings of Beirut that had seen heavy civilian casualties, testing Israel's relationship with the United States in the process. America sent troops to help negotiate the PLO's exit from Lebanon, withdrawing them after negotiating a ceasefire that ostensibly protected Palestinian civilians. Legal findings After 400,000 Peace Now protesters rallied in Tel Aviv to demand an official government inquiry into the massacres, the official Israeli government investigation into the massacre at Sabra and Shatila, the Kahan Commission (1982), was conducted. The inquiry found that the Israeli Defense Forces were indirectly responsible for the massacre since IDF troops held the area. The commission determined that the killings were carried out by a Phalangist unit acting on its own, but its entry was known to Israel and approved by Sharon. Prime Minister Begin was also found responsible for not exercising greater involvement and awareness in the matter of introducing the Phalangists into the camps. The commission also concluded that Sharon bore personal responsibility "for ignoring the danger of bloodshed and revenge [and] not taking appropriate measures to prevent bloodshed". It said Sharon's negligence in protecting the civilian population of Beirut, which had come under Israeli control, amounted to a dereliction of duty of the minister. In early 1983, the commission recommended the removal of Sharon from his post as defense minister and stated: We have found ... that the Minister of Defense [Ariel Sharon] bears personal responsibility. In our opinion, it is fitting that the Minister of Defense draw the appropriate personal conclusions arising out of the defects revealed with regard to the manner in which he discharged the duties of his office— and if necessary, that the Prime Minister consider whether he should exercise his authority ... to ... remove [him] from office." Sharon initially refused to resign as defense minister, and Begin refused to fire him. After a grenade was thrown into a dispersing crowd at an Israeli Peace Now march, killing Emil Grunzweig and injuring 10 others, a compromise was reached: Sharon agreed to forfeit the post of defense minister but stayed in the cabinet as a minister without portfolio. Sharon's resignation as defense minister is listed as one of the important events of the Tenth Knesset. In its 21 February 1983 issue, Time published an article implying that Sharon was directly responsible for the massacres. Sharon sued Time for libel in American and Israeli courts. Although the jury concluded that the Time article included false allegations, they found that the magazine had not acted with actual malice and so was not guilty of libel. On 18 June 2001, relatives of the victims of the Sabra massacre began proceedings in Belgium to have Sharon indicted on alleged war crimes charges. Elie Hobeika, the leader of the Phalange militia who carried out the massacres, was assassinated in January 2002, several months before he was scheduled to testify trial. Prior to his assassination, he had "specifically stated that he did not plan to identify Sharon as being responsible for Sabra and Shatila." Political downturn and recovery After his dismissal from the Defense Ministry post, Sharon remained in successive governments as a minister without portfolio (1983–1984), Minister for Trade and Industry (1984–1990), and Minister of Housing Construction (1990–1992). In the Knesset, he was member of the Foreign Affairs and Defense committee (1990–1992) and Chairman of the committee overseeing Jewish immigration from the Soviet Union. During this period he was a rival to then prime minister Yitzhak Shamir, but failed in various bids to replace him as chairman of Likud. Their rivalry reached a head in February 1990, when Sharon grabbed the microphone from Shamir, who was addressing the Likud central committee, and famously exclaimed: "Who's for wiping out terrorism?" The incident was widely viewed as an apparent coup attempt against Shamir's leadership of the party. Sharon unsuccessfully challenged Shamir in the 1984 Herut leadership election and the 1992 Likud leadership election. In Benjamin Netanyahu's 1996–1999 government, Sharon was Minister of National Infrastructure (1996–98), and Foreign Minister (1998–99). Upon the election of the Barak Labor government, Sharon became leader of the Likud party. Opposition to the NATO bombing of Yugoslavia Ariel Sharon criticised the NATO bombing of Yugoslavia in 1999 as an act of "brutal interventionism". Sharon said both Serbia and Kosovo have been victims of violence. He said prior to the current Yugoslav campaign against Kosovo Albanians, Serbians were the targets of attacks in the Kosovo province. "Israel has a clear policy. We are against aggressive actions. We are against hurting innocent people. I hope that the sides will return to the negotiating table as soon as possible." During the crisis, Elyakim Haetzni said the Serbs should be the first to receive Israeli aid. "There are our traditional friends," he told Israel Radio." It was suggested that Sharon may have supported the Yugoslav position because of the Serbian population's history of saving Jews during the holocaust. On Sharon's death, Serbian minister Aleksandar Vulin stated: The Serbian people will remember Sharon for opposing the 1999 NATO bombing campaign against the former Yugoslavia and advocating respect for sovereignty of other nations and a policy of not interfering with their internal affairs. Campaign for Prime Minister, 2000–2001 On 28 September 2000, Sharon and an escort of over 1,000 Israeli police officers visited the Temple Mount complex, site of the Dome of the Rock and al-Aqsa Mosque, the holiest place in the world to Jews and the third holiest site in Islam. Sharon declared that the complex would remain under perpetual Israeli control. Palestinian commentators accused Sharon of purposely inflaming emotions with the event to provoke a violent response and obstruct success of delicate ongoing peace talks. On the following day, a large number of Palestinian demonstrators and an Israeli police contingent confronted each other at the site. According to the U.S. State Department, "Palestinians held large demonstrations and threw stones at police in the vicinity of the Western Wall. Police used rubber-coated metal bullets and live ammunition to disperse the demonstrators, killing 4 persons and injuring about 200." According to the government of Israel, 14 policemen were injured. Sharon's visit, a few months before his election as Prime Minister, came after archeologists claimed that extensive building operations at the site were destroying priceless antiquities. Sharon's supporters claim that Yasser Arafat and the Palestinian National Authority planned the Second Intifada months prior to Sharon's visit. They state that Palestinian security chief Jabril Rajoub provided assurances that if Sharon did not enter the mosques, no problems would arise. They also often quote statements by Palestinian Authority officials, particularly Imad Falouji, the P.A. Communications Minister, who admitted months after Sharon's visit that the violence had been planned in July, far in advance of Sharon's visit, stating the intifada "was carefully planned since the return of (Palestinian President) Yasser Arafat from Camp David negotiations rejecting the U.S. conditions". According to the Mitchell Report, the government of Israel asserted that the immediate catalyst for the violence was the breakdown of the Camp David negotiations on 25 July 2000 and the "widespread appreciation in the international community of Palestinian responsibility for the impasse." In this view, Palestinian violence was planned by the PA leadership, and was aimed at "provoking and incurring Palestinian casualties as a means of regaining the diplomatic initiative." The Mitchell Report found that the Sharon visit did not cause the Al-Aqsa Intifada. But it was poorly timed and the provocative effect should have been foreseen; indeed, it was foreseen by those who urged that the visit be prohibited. More significant were the events that followed: The decision of the Israeli police on 29 September to use lethal means against the Palestinian demonstrators. In addition, the report stated, Accordingly, we have no basis on which to conclude that there was a deliberate plan by the PA [Palestinian Authority] to initiate a campaign of violence at the first opportunity; or to conclude that there was a deliberate plan by the GOI [Government of Israel] to respond with lethal force. The Or Commission, an Israeli panel of inquiry appointed to investigate the October 2000 events, criticised the Israeli police for being unprepared for the riots and possibly using excessive force to disperse the mobs, resulting in the deaths of 12 Arab Israeli, one Jewish and one Palestinian citizens. Prime Minister (2001–2006) After the collapse of Barak's government, Sharon was elected Prime Minister on 6 February 2001, defeating Barak 62 percent to 38 percent. Sharon's senior adviser was Raanan Gissin. In his first act as prime minister, Sharon invited the Labor Party to join in a coalition with Likud. After Israel was struck by a wave of suicide bombings in 2002, Sharon decided to launch Operation Defensive Shield and began the construction of a barrier around the West Bank. A survey conducted by Tel Aviv University's Jaffe Center in May 2004 found that 80% of Jewish Israelis believed that the Israel Defense Forces had succeeded in militarily countering the Al-Aqsa Intifada. The election of the more pro-Russian Sharon, as well as the more pro-Israel Vladimir Putin, led to an improvement in Israel–Russia relations. In September 2003, Sharon became the first prime minister of Israel to visit India, saying that Israel regarded India as one of the most important countries in the world. Some analysts speculated on the development of a three-way military axis of New Delhi, Washington, D.C., and Jerusalem. On 20 July 2004, Sharon called on French Jews to emigrate from France to Israel immediately, in light of an increase in antisemitism in France (94 antisemitic assaults were reported in the first six months of 2004, compared to 47 in 2003). France has the third-largest Jewish population in the world (about 600,000 people). Sharon observed that an "unfettered anti-Semitism" reigned in France. The French government responded by describing his comments as "unacceptable", as did the French representative Jewish organization CRIF, which denied Sharon's claim of intense anti-Semitism in French society. An Israeli spokesperson later claimed that Sharon had been misunderstood. France then postponed a visit by Sharon. Upon his visit, both Sharon and French President Jacques Chirac were described as showing a willingness to put the issue behind them. Unilateral disengagement In September 2001, Sharon stated for the first time that Palestinians should have the right to establish their own land west of the Jordan River. In May 2003, Sharon endorsed the Road Map for Peace put forth by the United States, the European Union and Russia, which opened a dialogue with Mahmud Abbas, and stated his commitment to the creation of a Palestinian state in the future. He embarked on a course of unilateral withdrawal from the Gaza Strip, while maintaining control of its coastline and airspace. Sharon's plan was welcomed by both the Palestinian Authority and Israel's left wing as a step towards a final peace settlement. However, it was greeted with opposition from within his own Likud party and from other right wing Israelis, on national security, military, and religious grounds. Disengagement from Gaza On 1 December 2004, Sharon dismissed five ministers from the Shinui party for voting against the government's 2005 budget. In January 2005, Sharon formed a national unity government that included representatives of Likud, Labor, and Meimad and Degel HaTorah as "out-of-government" supporters without any seats in the government (United Torah Judaism parties usually reject having ministerial offices as a policy). Between 16 and 30 August 2005, Sharon controversially expelled 9,480 Jewish settlers from 21 settlements in Gaza and four settlements in the northern West Bank. Once it became clear that the evictions were definitely going ahead, a group of conservative Rabbis, led by Yosef Dayan, placed an ancient curse on Sharon known as the Pulsa diNura, calling on the Angel of Death to intervene and kill him. After Israeli soldiers bulldozed every settlement structure except for several former synagogues, Israeli soldiers formally left Gaza on 11 September 2005 and closed the border fence at Kissufim. While his decision to withdraw from Gaza sparked bitter protests from members of the Likud party and the settler movement, opinion polls showed that it was a popular move among most of the Israeli electorate, with more than 80 percent of Israelis backing the plans. On 27 September 2005, Sharon narrowly defeated a leadership challenge by a 52–48 percent vote. The move was initiated within the central committee of the governing Likud party by Sharon's main rival, Benjamin Netanyahu, who had left the cabinet to protest Sharon's withdrawal from Gaza. The measure was an attempt by Netanyahu to call an early primary in November 2005 to choose the party's leader. Founding of Kadima On 21 November 2005, Sharon resigned as head of Likud, and dissolved parliament to form a new centrist party called Kadima ("Forward"). November polls indicated that Sharon was likely to be returned to the prime ministership. On 20 December 2005, Sharon's longtime rival Netanyahu was elected his successor as leader of Likud. Following Sharon's incapacitation, Ehud Olmert replaced Sharon as Kadima's leader, for the nearing general elections. Likud, along with the Labor Party, were Kadimas chief rivals in the March 2006 elections. Sharon's stroke occurred a few months before he had been expected to win a new election and was widely interpreted as planning on "clearing Israel out of most of the West Bank", in a series of unilateral withdrawals. In the elections, which saw Israel's lowest-ever voter turnout of 64 percent (the number usually averages on the high 70%), Kadima, headed by Olmert, received the most Knesset seats, followed by Labor. The new governing coalition installed in May 2006 included Kadima, with Olmert as Prime Minister, Labor (including Amir Peretz as Defense Minister), the Pensioners' Party (Gil), the Shas religious party, and Israel Beytenu. Alleged fundraising irregularities and Greek island affair During the latter part of his career, Sharon was investigated for alleged involvement in a number of financial scandals, in particular, the Greek island affair and irregularities of fundraising during the 1999 election campaign. In the Greek island affair, Sharon was accused of promising (during his term as Foreign Minister) to help Israeli businessman David Appel in his development project on a Greek island in exchange for large consultancy payments to Sharon's son Gilad. The charges were later dropped due to lack of evidence. In the 1999 election fundraising scandal, Sharon was not charged with any wrongdoing, but his son Omri, a Knesset member at the time, was charged and sentenced in 2006 to nine months in prison. To avoid a potential conflict of interest in relation to these investigations, Sharon was not involved in the confirmation of the appointment of a new attorney general, Menahem Mazuz, in 2005. On 10 December 2005, Israeli police raided Martin Schlaff's apartment in Jerusalem. Another suspect in the case was Robert Nowikovsky, an Austrian involved in Russian state-owned company Gazprom's business activities in Europe. According to Haaretz, "The $3 million that parachuted into Gilad and Omri Sharon's bank account toward the end of 2002 was transferred there in the context of a consultancy contract for development of kolkhozes (collective farms) in Russia. Gilad Sharon was brought into the campaign to make the wilderness bloom in Russia by Getex, a large Russian-based exporter of seeds (peas, millet, wheat) from Eastern Europe. Getex also has ties with Israeli firms involved in exporting wheat from Ukraine, for example. The company owns farms in Eastern Europe and is considered large and prominent in its field. It has its Vienna offices in the same building as Jurimex, which was behind the $1-million guarantee to the Yisrael Beiteinu party." On 17 December, police found evidence of a $3 million bribe paid to Sharon's sons. Shortly afterwards, Sharon suffered a stroke. Illness, incapacitation and death (2006–14) Sharon had been obese since the 1980s, and also had suspected chronic high blood pressure and high cholesterol – at tall, he was reputed to weigh . Stories of Sharon's appetite and obesity were legendary in Israel. He would often joke about his love of food and expansive girth. His staff car would reportedly be stocked with snacks, vodka, and caviar. In October 2004 when asked why he did not wear a bulletproof vest despite frequent death threats, Sharon smiled and replied, "There is none that fits my size". He was a daily consumer of cigars and luxury foods. Numerous attempts by doctors, friends, and staff to impose a balanced diet on Sharon were unsuccessful. Sharon was hospitalized on 18 December 2005, after suffering a minor ischemic stroke. During his hospital stay, doctors discovered a heart defect requiring surgery and ordered bed rest pending a cardiac catheterization scheduled for 5 January 2006. Instead, Sharon immediately returned to work and suffered a hemorrhagic stroke on 4 January. He was rushed to Hadassah Medical Center in Jerusalem. After two surgeries lasting 7 and 14 hours, doctors stopped the bleeding in Sharon's brain, but were unable to prevent him from entering into a coma. Subsequent media reports indicated that Sharon had been diagnosed with cerebral amyloid angiopathy (CAA) during his December hospitalisation. Hadassah Hospital Director Shlomo Mor-Yosef declined to respond to comments that the combination of CAA and blood thinners after Sharon's December stroke might have caused his more serious subsequent stroke. Ehud Olmert became Acting Prime Minister the night of Sharon's second stroke, while Sharon officially remained in office. Knesset elections followed in March, with Olmert and Sharon's Kadima party winning a plurality. The next month, the Israeli Cabinet declared Sharon permanently incapacitated and Olmert became Interim Prime Minister on 14 April 2006 and Prime Minister in his own right on 4 May. Sharon underwent a series of subsequent surgeries related to his state. In May 2006, he was transferred to a long-term care facility in Sheba Medical Center. In July of that year, he was briefly taken to the hospital's intensive care unit to be treated for bacteria in his blood, before returning to the long-term care facility on 6 November 2006. Sharon would remain at Sheba Medical Center until his death. Medical experts indicated that his cognitive abilities had likely been destroyed by the stroke. His condition worsened from late 2013, and Sharon suffered from renal failure on 1 January 2014. After spending eight years in a coma, Sharon died at 14:00 local time (12:00 UTC) on 11 January 2014. Sharon's state funeral was held on 13 January in accordance with Jewish burial customs, which require that interment take place as soon after death as possible. His body lay in state in the Knesset Plaza from 12 January until the official ceremony, followed by a funeral held at the family's ranch in the Negev Desert. Sharon was buried beside his wife, Lily. Personal life Sharon was married twice, to two sisters, Margalit and Lily Zimmerman, who were from Romania. Sharon met Margalit in 1947 when she was 16, while she was tending a vegetable field, and married her in 1953, shortly after becoming a military instructor. Margalit was a supervisory psychiatric nurse. They had one son, Gur. Margalit died in a car accident in May 1962 and Gur died in October 1967, aged 11, after a friend accidentally shot him while the two children were playing with a rifle at the Sharon family home. After Margalit's death, Sharon married her younger sister, Lily. They had two sons, Omri and Gilad, and six grandchildren. Lily Sharon died of lung cancer in 2000. Sharon's sister, Yehudit (Dita) married Dr. Shmuel Mandel. In the 1950s, the couple permanently left Israel and emigrated to the United States. This caused a permanent rift in the family. Shmuel and Vera Scheinerman were greatly hurt by their daughter's choice to leave Israel. As a result, Vera Scheinerman willed only a small part of her estate to Dita, an act which enraged her. At one point, Dita decided to return to Israel, but after Vera was informed by the Israel Lands Administration that it would not be legally possible to split the family property between Ariel and Dita, and informed her that she would not be able to build a home there, Dita, believing she was being lied to, permanently cut her family in Israel off, and refused to attend the funerals of her mother and sister-in-law. She reestablished contact after Sharon's stroke. Sharon's sister has rarely been mentioned in biographies of him: he himself rarely acknowledged her and only mentioned her twice in his autobiography. Recognition The Ariel Sharon Park, an environmental park near Tel Aviv, is named for him. In the Negev desert, the IDF is currently building its city of training bases, Camp Ariel Sharon. In total, a NIS 50 billion project, the city of bases is named after Ariel Sharon, the largest active construction project in Israel, it is to become the largest IDF base in Israel. Overview of offices held Sharon served as prime minister (Israel's head of government) from 7 March 2001 through 14 April 2006 (with Ehud Barak serving as acting prime minister beginning 4 January 2006, after Sharon slipped into a coma). As prime minister he led the 12th government during the 15th Knesset and the 13th government during the 16th Knesset. Sharon served in the Knesset, first for several months in 1973, and later from 1977 through 2006. Sharon. From July 1999 through July 2000, Sharon served as the unofficial/honorary Knesset's opposition leader. Thereafter, from July 2000 through March 2001, he served as the first official designated Knesset opposition leader. Sharon served as leader of the Likud party from 1999 through 2005, leaving to create Kadima which he led from 2006 through early 2006 (when he fell into a coma). In addition to these positions and ministerial roles, Sharon also served as a special aide to Prime Minister Yitzhak Rabin from June 1975 through March 1976.

Ann Druyan ( ; born June 13, 1949) is an Emmy and Peabody Award-winning American documentary producer and director specializing in the communication of science. She co-wrote the 1980 PBS documentary series Cosmos, hosted by Carl Sagan, whom she married in 1981. She is the creator, producer, and writer of the 2014 sequel, Cosmos: A Spacetime Odyssey and its sequel series, Cosmos: Possible Worlds, as well as the book of the same name. She is credited with directing episodes of both series as well. In the late 1970s, Druyan became the Creative Director of NASA's Voyager Interstellar Message Project, which produced the golden discs affixed to both the Voyager 1 and Voyager 2 spacecraft. She also published a novel, A Famous Broken Heart, in 1977, and later co-wrote several best selling non-fiction books with Carl Sagan. Early life Druyan was born in Queens, New York, the daughter of Pearl A. () and Harry Druyan, who co-owned a knitwear firm. Druyan's early interest in math and science was, in her word, "derailed" when a junior high-school teacher ridiculed a question she asked about the universality of . "I raised my hand and said, 'You mean this applies to every circle in the universe?', and the teacher told me not to ask stupid questions. And there I was having this religious experience, and she made me feel like such a fool. I was completely flummoxed from then on until after college." Druyan characterized her three years at New York University as "disastrous", and it was only after she left school without graduating that she discovered the pre-Socratic philosophers and began educating herself, thus leading to a renewed interest in science. Career In the late 1970s, Druyan became the Creative Director of NASA's Voyager Interstellar Message Project. As creative director, Druyan worked with a team to design a complex message, including music and images, for possible alien civilizations. These golden phonograph records affixed to the Voyager 1 and Voyager 2 spacecraft are now beyond the outermost planets of the solar system, and Voyager 1 has entered interstellar space. Both records have a projected shelf life of one billion years. Druyan's role on the project was discussed on the July 8, 2018, 60 Minutes segment "The Little Spacecraft That Could". In the segment, Druyan explained her insistence that Chuck Berry's "Johnny B. Goode" be included on the Golden Record, saying: "...Johnny B. Goode, rock and roll, was the music of motion, of moving, getting to someplace you've never been before, and the odds are against you, but you want to go. That was Voyager." The segment also discussed Sagan's suggestion, in 1990, that Voyager 1 turn its cameras back towards Earth to take a series of photographs showing the planets of our solar system. The shots, showing Earth from a distance of 3.7 billion miles as a small point of bluish light, became the basis for Sagan's famous "Pale Blue Dot" passage, first published in Pale Blue Dot: A Vision of the Human Future in Space (1994). During that time, Druyan also co-wrote (with Carl Sagan and Steven Soter) the 1980 PBS documentary series Cosmos, hosted by Carl Sagan. The thirteen-part series covered a wide range of scientific subjects, including the origin of life and a perspective of our place in the universe. It was highly acclaimed, and became the most widely watched series in the history of American public television at that time. The series won two Emmys and a Peabody Award, and has since been broadcast in more than 60 countries and seen by over 500 million people. A book was also published to accompany the series. , it is still the most widely watched PBS series in the world. Druyan wrote and produced the 1987 PBS NOVA episode "Confessions of a Weaponeer" on the life of President Eisenhower's Science Advisor George Kistiakowsky. In 2000, Druyan, together with Steve Soter, co-wrote Passport to the Universe, the inaugural planetarium show for the Rose Center for Earth and Space at the American Natural History Museum's Hayden Planetarium. The attraction is narrated by Tom Hanks. Druyan and Soter also co-wrote The Search for Life: Are We Alone, narrated by Harrison Ford, which also debuted at the Hayden's Rose Center. In 2000, Druyan co-founded Cosmos Studios, Inc, with Joseph Firmage. As CEO of Cosmos Studios, Druyan produces science-based entertainment for all media. In addition to Cosmos: A SpaceTime Odyssey, Cosmos Studios has produced Cosmic Africa, Lost Dinosaurs of Egypt, and the Emmy-nominated documentary Cosmic Journey: The Voyager Interstellar Mission and Message. In 2009, she distributed a series of podcasts called At Home in the Cosmos with Annie Druyan, in which she described her works, the life of her husband, Carl Sagan, and their marriage. Druyan was one of the three writers of the TV series Cosmos: A Personal Voyage, along with Carl Sagan and Steven Soter. Druyan is credited, with Carl Sagan, as the co-creator and co-producer of the 1997 feature film Contact. In 2011, it was announced that Druyan would executive produce, co-write, and be one of the episodic directors for a sequel to Cosmos: A Personal Voyage, to be called Cosmos: A Spacetime Odyssey, which began airing in March 2014. Episodes premiered on Fox and also aired on National Geographic Channel on the following night. At the time of its release, Fox gave the series the largest global rollout of a television series ever, debuting it in 180 countries. The premiere episode was shown across nine of Fox's cable properties in addition to the broadcast network in a "roadblock" style premiere. The series went on to become the most-watched series ever for National Geographic Channel International, with at least some part of the 13-episode series watched by 135 million people, including 45 million in the U.S. In March 2020, a third season of Cosmos, named Cosmos: Possible Worlds, for which Druyan was executive producer, writer, and director, premiered on National Geographic. Druyan also said: "I very much have season four in mind, and I know what it's going to be. And I even know some of the stories that I want to tell in it." Writing Druyan's first novel, A Famous Broken Heart, was published in 1977. Druyan co-wrote six New York Times best-sellers with Carl Sagan, including: Comet, Shadows of Forgotten Ancestors, and The Demon-Haunted World. She is co-author, along with Carl Sagan, F. D. Drake, Timothy Ferris, Jon Lomberg and Linda Salzman Sagan, of Murmurs Of Earth: The Voyager Interstellar Record. She also wrote the updated introduction to Sagan's book The Cosmic Connection and the epilogue of Billions and Billions. She wrote the introduction to, and edited The Varieties of Scientific Experience, published from Sagan's 1985 Gifford lectures. In February 2020, Druyan published Cosmos: Possible Worlds, a companion volume to the television series of the same name, which premiered in March 2020. Work in science Druyan is a fellow of the Committee for the Scientific Investigation of Claims for the Paranormal (CSICOP). Druyan served as program director of the first solar-sail deep-space mission, Cosmos 1, launched on a Russian ICBM in 2005. Druyan is involved in multiple Breakthrough Initiatives. With Frank Drake, Druyan is the co-chair of Breakthrough Message and also a member of Breakthrough Starshot. She is a member of the advisory board of The Carl Sagan Institute. Activism Druyan has for many years been a vocal advocate for nuclear disarmament. She was arrested three times at the Mercury, Nevada nuclear test site during Mikhail Gorbachev's unilateral moratorium on underground nuclear testing, with which President Ronald Reagan did not cooperate. This included an arrest in June 1986, when Druyan crossed a white painted line indicating the test site's boundary; Sagan, who attended the same protest with Druyan, was not arrested. In the early 1990s, Druyan worked with Sagan and then-Senator Al Gore, Jr. and a host of religious and scientific leaders to bring the scientific and religious worlds together in a unified effort to preserve the environment, resulting in the Declaration of the 'Mission to Washington. Druyan served as a founding director of the Children's Health Fund until the spring of 2004, a project that provides mobile pediatric care to homeless and disadvantaged children in more than half a dozen cities. She currently serves a member of their Advisory Board. Druyan has served on the Board of Directors of the National Organization for the Reform of Marijuana Laws (NORML) for over 10 years and was president from 2006 to 2010. Honors An asteroid discovered in 1998 was named in Druyan's honor by its discoverer Eleanor F. Helin. In a 2020 interview with Skeptical Inquirer, Druyan discussed 4970 Druyan and the asteroid named after her late husband, saying that 4970 Druyan is in a "wedding ring orbit" around the Sun with 2709 Sagan. Druyan was presented with a plaque on Sagan's sixtieth birthday, which is inscribed: "Asteroid 2709 Sagan in eternal companion orbit with asteroid 4970 Druyan, symbolic of their love and admiration for each other." In November 2006, Druyan was a speaker at "Beyond Belief: Science, Religion, Reason and Survival". In January 2007, she was a juror at the 2007 Sundance Film Festival, responsible for selecting the winner of the Alfred P. Sloan Prize for films about science and technology. In November 2007, Druyan was awarded the title of "Humanist Laureate" by the International Academy of Humanism. In October 2019, the Center for Inquiry West opened the Carl Sagan–Ann Druyan Theater in Los Angeles. Religious and philosophical views In an interview with Joel Achenbach of The Washington Post, Druyan stated that her early interest in science stemmed from a fascination with Karl Marx. Achenbach commented that "She had, at the time, rather vaporous standards of evidence", a reference to her belief in the ancient astronauts of Erich von Däniken and the theories of Immanuel Velikovsky pertaining to the solar system. Concerning the death of her husband she stated: When my husband died, because he was so famous and known for not being a believer, many people would come up to me—it still sometimes happens—and ask me if Carl changed at the end and converted to a belief in an afterlife. They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don't ever expect to be reunited with Carl. Personal life Druyan and Sagan's working and resulting romantic relationship has been the subject of numerous treatments in popular culture, including the Radiolab episode "Carl Sagan and Ann Druyan's Ultimate Mix Tape" and a segment of the Comedy Central program Drunk Historys episode "Space". The asteroid 4970 Druyan, which is in a companion orbit with asteroid 2709 Sagan named after Druyan's late husband, is named after Druyan. In 2015, it was announced that Warner Brothers was in development on a drama about Sagan and Druyan's relationship, to be produced by producer Lynda Obst and Druyan. In 2020, Sagan and Druyan's daughter Sasha Sagan released a book For Small Creatures Such As We: Rituals for Finding Meaning in our Unlikely World, which discusses life with her parents and her father's death when she was fourteen years old. Druyan also gave Sasha a recurring role in Cosmos: Possible Worlds, where she played her own grandmother, including in the episode Man of a Trillion Worlds, which featured the life of Carl Sagan.

The Aimaq () or Chahar Aimaq (), also transliterated as Aimagh, Aimak and Aymaq, are a collection of Sunni and mostly Persian-speaking nomadic and semi-nomadic tribes. They live mostly in the central and western highlands of Afghanistan, especially in Ghor, Badghis. Aimaqs were originally known as chahar ("four") Aymaqs: the Taymani (the main element in the population of Ghor), the Firozkohi (mostly in Badghis), the Jamshidi and the Timuri. Other sources state that the Aimaq Hazara are one of the Chahar, with the Timuri instead being of the "lesser Aimaqs" or Aimaq-e digar ("other Aimaqs"). The Aimaq speak several subdialects of the Aimaq dialect of Persian language, but some southern groups of Taymani, Firozkohi, and northeastern Timuri Aimaqs have adopted the Pashto language. Origin and culture The Aimaqs claim different origins based on their tribal background. Some claim to be descended from the troops of Genghis Khan. Other tribes such as the Taymani (Aimaq tribe) and Firozkohi claim descent from other Pashtun tribes. Aimaq is a Mongolic word that means "tribe" or "grazing territory". Of all Aimaqs, Aimaq Hazara and Timuri are closest to the Turco-Mongol tradition since they are semi-nomadic tribes and some of them live in yurts, whereas other Aimaqs live in traditional Afghan black tents. The Aimaq are largely nomadic to semi-nomadic goat and sheep herders. They also trade with villages and farmers during migrations for pastures for their livestock. The material culture and foodstuffs of the Aimaq include skins, carpets, milk, dairy products and more. They trade these products to settled peoples in return for vegetables, grains, fruits, nuts, and other types of foods and goods. Classification of tribes Aimaq tribes Demographics Estimates of the Aimaq population vary between 250,000 and 500,000. They are largely Sunni Muslims—except for the Jamshidi who are mainly Ismaili Shia in the main—and in contrast to the Hazara, who are mostly Shia Muslims.

The Agra Canal is an important Indian irrigation work which starts from Okhla in Delhi. The Agra canal originates from Okhla barrage, downstream of Nizamuddin bridge. The Canal receives its water from the Yamuna River at Okhla, about 10 km to the south of New Delhi. The weir across the Yamuna was constructed of locally quarried stone. It was about 800-yards long, and rises seven-feet above the summer level of the river. From Okhla the canal follows a route south then southeast for in the high land between the Khari-Nadi and the Yamuna and finally joins the Utanga River about below Agra. Navigable branches connect the canal with Mathura and Agra. The canal irrigates about 1.5 lakh MOS:DIGITS hectares in Agra, and Mathura in Uttar Pradesh, Faridabad in Haryana, Bharatpur in Rajasthan and also some parts of Delhi. History The canal opened in the year 1874. In the beginning, it was available for navigation, in Delhi, erstwhile Gurgaon, Mathura and Agra Districts, and Bharatpur State. Later, navigation was stopped in 1904 and the canal has, since then, been exclusively used for irrigation purposes only. At present, the canal does not flow in Gurgaon district, but only in Faridabad, which was earlier a part of Gurgaon. In recent times, Agra canal is an important landmark which separates Greater Faridabad from Faridabad. References The Agra Canal also has many places to visit along its coast.

Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for recent global warming and related climate changes on Earth. The effort has focused on changes observed during the period of instrumental temperature record, particularly in the last 50 years. This is the period when human activity has grown fastest and observations of the atmosphere above the surface have become available. According to the Intergovernmental Panel on Climate Change (IPCC), it is "extremely likely" that human influence was the dominant cause of global warming between 1951 and 2010. Likely human contribution is 93%–123% of the observed 1951–2010 temperature change. Some of the main human activities that contribute to global warming are: increasing atmospheric concentrations of greenhouse gases, for a warming effect global changes to land surface, such as deforestation, for a warming effect increasing atmospheric concentrations of aerosols, mainly for a cooling effect In addition to human activities, some natural mechanisms can also cause climate change, including for example, climate oscillations, changes in solar activity, and volcanic activity. Multiple lines of evidence support attribution of recent climate change to human activities: A physical understanding of the climate system: greenhouse gas concentrations have increased and their warming properties are well-established. Historical estimates of past climate changes suggest that the recent changes in global surface temperature are unusual. Computer-based climate models are unable to replicate the observed warming unless human greenhouse gas emissions are included. Natural forces alone (such as solar and volcanic activity) cannot explain the observed warming. The IPCC's attribution of recent global warming to human activities reflects the view of the scientific community, and is also supported by 196 other scientific organizations worldwide. () Background Factors affecting Earth's climate can be broken down into forcings, feedbacks and internal variations. A forcing is something that is imposed externally on the climate system. External forcings include natural phenomena such as volcanic eruptions and variations in the sun's output. Human activities can also impose forcings, for example, through changing the composition of Earth's atmosphere. Radiative forcing is a measure of how various factors alter the energy balance of planet Earth. A positive radiative forcing will lead towards a warming of the surface and, over time, the climate system. Between the start of the Industrial Revolution in 1750, and the year 2005, the increase in the atmospheric concentration of carbon dioxide (chemical formula: ) led to a positive radiative forcing, averaged over the Earth's surface area, of about 1.66 watts per square metre (abbreviated W m−2). Climate feedbacks can either amplify or dampen the response of the climate to a given forcing. There are many feedback mechanisms in the climate system that can either amplify (a positive feedback) or diminish (a negative feedback) the effects of a change in climate forcing. The climate system will vary in response to changes in forcings. The climate system will show internal variability both in the presence and absence of forcings imposed on it, (see images opposite). This internal variability is a result of complex interactions between components of the climate system, such as the coupling between the atmosphere and ocean (see also the later section on Internal climate variability and global warming). An example of internal variability is the El Niño–Southern Oscillation. Detection vs. attribution Detection and attribution of climate signals, as well as its common-sense meaning, has a more precise definition within the climate change literature, as expressed by the IPCC. Detection of a climate signal does not always imply significant attribution. The IPCC's Fourth Assessment Report says "it is extremely likely that human activities have exerted a substantial net warming influence on climate since 1750," where "extremely likely" indicates a probability greater than 95%. Detection of a signal requires demonstrating that an observed change is statistically significantly different from that which can be explained by natural internal variability. Attribution requires demonstrating that a signal is: unlikely to be due entirely to internal variability; consistent with the estimated responses to the given combination of anthropogenic and natural forcing not consistent with alternative, physically plausible explanations of recent climate change that exclude important elements of the given combination of forcings. Key attributions Greenhouse gases is absorbed and emitted naturally as part of the carbon cycle, through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange. Human activities, such as the burning of fossil fuels and changes in land use (see below), release large amounts of carbon to the atmosphere, causing concentrations in the atmosphere to rise. The high-accuracy measurements of atmospheric concentration, initiated by Charles David Keeling in 1958, constitute the master time series documenting the changing composition of the atmosphere. These data have iconic status in climate change science as evidence of the effect of human activities on the chemical composition of the global atmosphere. In May 2019, the concentration of in the atmosphere reached 415 ppm. The last time when it reached this level was 2.6–5.3 million years ago. Without human intervention, it would be 280 ppm. Along with , methane and to a lesser extent nitrous oxide are also major forcing contributors to the greenhouse effect. The Kyoto Protocol lists these together with hydrofluorocarbon (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are entirely artificial gases, as contributors to radiative forcing. The chart at right attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes, transportation fuels (generally fossil fuels), and agricultural by-products (mainly methane from enteric fermentation and nitrous oxide from fertilizer use). Water vapor Water vapor is the most abundant greenhouse gas and is the largest contributor to the natural greenhouse effect, despite having a short atmospheric lifetime (about 10 days). Some human activities can influence local water vapor levels. However, on a global scale, the concentration of water vapor is controlled by temperature, which influences overall rates of evaporation and precipitation. Therefore, the global concentration of water vapor is not substantially affected by direct human emissions. Land use Climate change is attributed to land use for two main reasons. Between 1750 and 2007, about two-thirds of anthropogenic emissions were produced from burning fossil fuels, and about one-third of emissions from changes in land use, primarily deforestation. Deforestation both reduces the amount of carbon dioxide absorbed by deforested regions and releases greenhouse gases directly, together with aerosols, through biomass burning that frequently accompanies it. Some of the causes of climate change are, generally, not connected with it directly in the media coverage. For example, the harm done by humans to the populations of Elephants and Monkeys contributes to deforestation therefore to climate change. A second reason that climate change has been attributed to land use is that the terrestrial albedo is often altered by use, which leads to radiative forcing. This effect is more significant locally than globally. Livestock and land use Worldwide, livestock production occupies 70% of all land used for agriculture, or 30% of the ice-free land surface of the Earth. More than 18% of anthropogenic greenhouse gas emissions are attributed to livestock and livestock-related activities such as deforestation and increasingly fuel-intensive farming practices. Specific attributions to the livestock sector include: 9% of global anthropogenic carbon dioxide emissions 35–40% of global anthropogenic methane emissions (chiefly due to enteric fermentation and manure) 64% of global anthropogenic nitrous oxide emissions, chiefly due to fertilizer use. Aerosols With virtual certainty, scientific consensus has attributed various forms of climate change, chiefly cooling effects, to aerosols, which are small particles or droplets suspended in the atmosphere. Key sources to which anthropogenic aerosols are attributed include: biomass burning such as slash-and-burn deforestation. Aerosols produced are primarily black carbon. industrial air pollution, which produces soot and airborne sulfates, nitrates, and ammonium dust produced by land use effects such as desertification Attribution of 20th-century climate change Over the past 150 years human activities have released increasing quantities of greenhouse gases into the atmosphere. This has led to increases in mean global temperature, or global warming. Other human effects are relevant—for example, sulphate aerosols are believed to have a cooling effect. Natural factors also contribute. According to the historical temperature record of the last century, the Earth's near-surface air temperature has risen around 0.74 ± 0.18 °Celsius (1.3 ± 0.32 °Fahrenheit). A historically important question in climate change research has regarded the relative importance of human activity and non-anthropogenic causes during the period of instrumental record. In the 1995 Second Assessment Report (SAR), the IPCC made the widely quoted statement that "The balance of evidence suggests a discernible human influence on global climate". The phrase "balance of evidence" suggested the (English) common-law standard of proof required in civil as opposed to criminal courts: not as high as "beyond reasonable doubt". In 2001 the Third Assessment Report (TAR) refined this, saying "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities". The 2007 Fourth Assessment Report (AR4) strengthened this finding: "Anthropogenic warming of the climate system is widespread and can be detected in temperature observations taken at the surface, in the free atmosphere and in the oceans. Evidence of the effect of external influences, both anthropogenic and natural, on the climate system has continued to accumulate since the TAR." Other findings of the IPCC Fourth Assessment Report include: "It is extremely unlikely (<5%) that the global pattern of warming during the past half century can be explained without external forcing (i.e., it is inconsistent with being the result of internal variability), and very unlikely that it is due to known natural external causes alone. The warming occurred in both the ocean and the atmosphere and took place at a time when natural external forcing factors would likely have produced cooling." "From new estimates of the combined anthropogenic forcing due to greenhouse gases, aerosols, and land surface changes, it is extremely likely (>95%) that human activities have exerted a substantial net warming influence on climate since 1750." "It is virtually certain that anthropogenic aerosols produce a net negative radiative forcing (cooling influence) with a greater magnitude in the Northern Hemisphere than in the Southern Hemisphere." Over the past five decades there has been a global warming of approximately 0.65 °C (1.17 °F) at the Earth's surface (see historical temperature record). Among the possible factors that could produce changes in global mean temperature are internal variability of the climate system, external forcing, an increase in concentration of greenhouse gases, or any combination of these. Current studies indicate that the increase in greenhouse gases, most notably , is mostly responsible for the observed warming. Evidence for this conclusion includes: Estimates of internal variability from climate models, and reconstructions of past temperatures, indicate that the warming is unlikely to be entirely natural. Climate models forced by natural factors and increased greenhouse gases and aerosols reproduce the observed global temperature changes; those forced by natural factors alone do not. "Fingerprint" methods (see below) indicate that the pattern of change is closer to that expected from greenhouse gas-forced change than from natural change. The plateau in warming from the 1940s to 1960s can be attributed largely to sulphate aerosol cooling. Details on attribution Recent scientific assessments find that most of the warming of the Earth's surface over the past 50 years has been caused by human activities (see also the section on scientific literature and opinion). This conclusion rests on multiple lines of evidence. Like the warming "signal" that has gradually emerged from the "noise" of natural climate variability, the scientific evidence for a human influence on global climate has accumulated over the past several decades, from many hundreds of studies. No single study is a "smoking gun." Nor has any single study or combination of studies undermined the large body of evidence supporting the conclusion that human activity is the primary driver of recent warming. The first line of evidence is based on a physical understanding of how greenhouse gases trap heat, how the climate system responds to increases in greenhouse gases, and how other human and natural factors influence climate. The second line of evidence is from indirect estimates of climate changes over the last 1,000 to 2,000 years. These records are obtained from living things and their remains (like tree rings and corals) and from physical quantities (like the ratio between lighter and heavier isotopes of oxygen in ice cores), which change in measurable ways as climate changes. The lesson from these data is that global surface temperatures over the last several decades are clearly unusual, in that they were higher than at any time during at least the past 400 years. For the Northern Hemisphere, the recent temperature rise is clearly unusual in at least the last 1,000 years (see graph opposite). The third line of evidence is based on the broad, qualitative consistency between observed changes in climate and the computer model simulations of how climate would be expected to change in response to human activities. For example, when climate models are run with historical increases in greenhouse gases, they show gradual warming of the Earth and ocean surface, increases in ocean heat content and the temperature of the lower atmosphere, a rise in global sea level, retreat of sea ice and snow cover, cooling of the stratosphere, an increase in the amount of atmospheric water vapor, and changes in large-scale precipitation and pressure patterns. These and other aspects of modelled climate change are in agreement with observations. "Fingerprint" studies Finally, there is extensive statistical evidence from so-called "fingerprint" studies. Each factor that affects climate produces a unique pattern of climate response, much as each person has a unique fingerprint. Fingerprint studies exploit these unique signatures, and allow detailed comparisons of modelled and observed climate change patterns. Scientists rely on such studies to attribute observed changes in climate to a particular cause or set of causes. In the real world, the climate changes that have occurred since the start of the Industrial Revolution are due to a complex mixture of human and natural causes. The importance of each individual influence in this mixture changes over time. Of course, there are not multiple Earths, which would allow an experimenter to change one factor at a time on each Earth, thus helping to isolate different fingerprints. Therefore, climate models are used to study how individual factors affect climate. For example, a single factor (like greenhouse gases) or a set of factors can be varied, and the response of the modelled climate system to these individual or combined changes can thus be studied. These projections have been confirmed by observations (shown above). For example, when climate model simulations of the last century include all of the major influences on climate, both human-induced and natural, they can reproduce many important features of observed climate change patterns. When human influences are removed from the model experiments, results suggest that the surface of the Earth would actually have cooled slightly over the last 50 years. The clear message from fingerprint studies is that the observed warming over the last half-century cannot be explained by natural factors, and is instead caused primarily by human factors. Another fingerprint of human effects on climate has been identified by looking at a slice through the layers of the atmosphere, and studying the pattern of temperature changes from the surface up through the stratosphere (see the section on solar activity). The earliest fingerprint work focused on changes in surface and atmospheric temperature. Scientists then applied fingerprint methods to a whole range of climate variables, identifying human-caused climate signals in the heat content of the oceans, the height of the tropopause (the boundary between the troposphere and stratosphere, which has shifted upward by hundreds of feet in recent decades), the geographical patterns of precipitation, drought, surface pressure, and the runoff from major river basins. Studies published after the appearance of the IPCC Fourth Assessment Report in 2007 have also found human fingerprints in the increased levels of atmospheric moisture (both close to the surface and over the full extent of the atmosphere), in the decline of Arctic sea ice extent, and in the patterns of changes in Arctic and Antarctic surface temperatures. The message from this entire body of work is that the climate system is telling a consistent story of increasingly dominant human influence – the changes in temperature, ice extent, moisture, and circulation patterns fit together in a physically consistent way, like pieces in a complex puzzle. Increasingly, this type of fingerprint work is shifting its emphasis. As noted, clear and compelling scientific evidence supports the case for a pronounced human influence on global climate. Much of the recent attention is now on climate changes at continental and regional scales, and on variables that can have large impacts on societies. For example, scientists have established causal links between human activities and the changes in snowpack, maximum and minimum (diurnal) temperature, and the seasonal timing of runoff over mountainous regions of the western United States. Human activity is likely to have made a substantial contribution to ocean surface temperature changes in hurricane formation regions. Researchers are also looking beyond the physical climate system, and are beginning to tie changes in the distribution and seasonal behaviour of plant and animal species to human-caused changes in temperature and precipitation. For over a decade, one aspect of the climate change story seemed to show a significant difference between models and observations. In the tropics, all models predicted that with a rise in greenhouse gases, the troposphere would be expected to warm more rapidly than the surface. Observations from weather balloons, satellites, and surface thermometers seemed to show the opposite behaviour (more rapid warming of the surface than the troposphere). This issue was a stumbling block in understanding the causes of climate change. It is now largely resolved. Research showed that there were large uncertainties in the satellite and weather balloon data. When uncertainties in models and observations are properly accounted for, newer observational data sets (with better treatment of known problems) are in agreement with climate model results. This does not mean, however, that all remaining differences between models and observations have been resolved. The observed changes in some climate variables, such as Arctic sea ice, some aspects of precipitation, and patterns of surface pressure, appear to be proceeding much more rapidly than models have projected. The reasons for these differences are not well understood. Nevertheless, the bottom-line conclusion from climate fingerprinting is that most of the observed changes studied to date are consistent with each other, and are also consistent with our scientific understanding of how the climate system would be expected to respond to the increase in heat-trapping gases resulting from human activities. Extreme weather events Scientific literature and opinion There are a number of examples of published and informal support for the consensus view. As mentioned earlier, the IPCC has concluded that most of the observed increase in globally averaged temperatures since the mid-20th century is "very likely" due to human activities. The IPCC's conclusions are consistent with those of several reports produced by the US National Research Council. A report published in 2009 by the U.S. Global Change Research Program concluded that "[global] warming is unequivocal and primarily human-induced." A number of scientific organizations have issued statements that support the consensus view: A 2004 essay in Science surveyed 928 abstracts related to climate change, and concluded that most journal reports accepted the consensus. a joint statement made in 2005 by the national science academies of the G8, and Brazil, China and India; a joint statement made in 2008 by the Network of African Science Academies. A 2010 paper in the Proceedings of the National Academy of Sciences found that among a pool of roughly 1,000 researchers who work directly on climate issues and publish the most frequently on the subject, 97% agree that anthropogenic climate change is happening. A 2011 paper from George Mason University published in the International Journal of Public Opinion Research, "The Structure of Scientific Opinion on Climate Change," collected the opinions of scientists in the earth, space, atmospheric, oceanic or hydrological sciences. The 489 survey respondents—representing nearly half of all those eligible according to the survey's specific standards – work in academia, government, and industry, and are members of prominent professional organizations. The study found that 97% of the 489 scientists surveyed agreed that global temperatures have risen over the past century. Moreover, 84% agreed that "human-induced greenhouse warming" is now occurring." Only 5% disagreed with the idea that human activity is a significant cause of global warming. Detection and attribution studies The IPCC Fourth Assessment Report (2007), concluded that attribution was possible for a number of observed changes in the climate (see effects of global warming). However, attribution was found to be more difficult when assessing changes over smaller regions (less than continental scale) and over short time periods (less than 50 years). Over larger regions, averaging reduces natural variability of the climate, making detection and attribution easier. In 1996, in a paper in Nature titled "A search for human influences on the thermal structure of the atmosphere", Benjamin D. Santer et al. wrote: "The observed spatial patterns of temperature change in the free atmosphere from 1963 to 1987 are similar to those predicted by state-of-the-art climate models incorporating various combinations of changes in carbon dioxide, anthropogenic sulphate aerosol and stratospheric ozone concentrations. The degree of pattern similarity between models and observations increases through this period. It is likely that this trend is partially due to human activities, although many uncertainties remain, particularly relating to estimates of natural variability." A 2002 paper in the Journal of Geophysical Research says "Our analysis suggests that the early twentieth century warming can best be explained by a combination of warming due to increases in greenhouse gases and natural forcing, some cooling due to other anthropogenic forcings, and a substantial, but not implausible, contribution from internal variability. In the second half of the century we find that the warming is largely caused by changes in greenhouse gases, with changes in sulphates and, perhaps, volcanic aerosol offsetting approximately one third of the warming." A 2005 review of detection and attribution studies by the International Ad hoc Detection and Attribution Group found that "natural drivers such as solar variability and volcanic activity are at most partially responsible for the large-scale temperature changes observed over the past century, and that a large fraction of the warming over the last 50 yr can be attributed to greenhouse gas increases. Thus, the recent research supports and strengthens the IPCC Third Assessment Report conclusion that 'most of the global warming over the past 50 years is likely due to the increase in greenhouse gases.'" Barnett and colleagues (2005) say that the observed warming of the oceans "cannot be explained by natural internal climate variability or solar and volcanic forcing, but is well simulated by two anthropogenically forced climate models," concluding that "it is of human origin, a conclusion robust to observational sampling and model differences". Two papers in the journal Science in August 2005 resolve the problem, evident at the time of the TAR, of tropospheric temperature trends (see also the section on "fingerprint" studies) . The UAH version of the record contained errors, and there is evidence of spurious cooling trends in the radiosonde record, particularly in the tropics. See satellite temperature measurements for details; and the 2006 US CCSP report. Multiple independent reconstructions of the temperature record of the past 1000 years confirm that the late 20th century is probably the warmest period in that time (see the preceding section -details on attribution). Solar activity Solar sunspot maximum occurs when the magnetic field of the Sun collapses and reverse as part of its average 11-year solar cycle (22 years for complete North to North restoration). The role of the Sun in recent climate change has been looked at by climate scientists. Since 1978, output from the Sun has been measured by satellites significantly more accurately than was previously possible from the surface. These measurements indicate that the Sun's total solar irradiance has not increased since 1978, so the warming during the past 30 years cannot be directly attributed to an increase in total solar energy reaching the Earth (see graph above, left). In the three decades since 1978, the combination of solar and volcanic activity probably had a slight cooling influence on the climate. Climate models have been used to examine the role of the Sun in recent climate change. Models are unable to reproduce the rapid warming observed in recent decades when they only take into account variations in total solar irradiance and volcanic activity. Models are, however, able to simulate the observed 20th century changes in temperature when they include all of the most important external forcings, including human influences and natural forcings. As has already been stated, Hegerl et al. (2007) concluded that greenhouse gas forcing had "very likely" caused most of the observed global warming since the mid-20th century. In making this conclusion, Hegerl et al. (2007) allowed for the possibility that climate models had been underestimated the effect of solar forcing. The role of solar activity in climate change has also been calculated over longer time periods using "proxy" datasets, such as tree rings. Models indicate that solar and volcanic forcings can explain periods of relative warmth and cold between AD 1000 and 1900, but human-induced forcings are needed to reproduce the late-20th century warming. Another line of evidence against the sun having caused recent climate change comes from looking at how temperatures at different levels in the Earth's atmosphere have changed. Models and observations (see figure above, middle) show that greenhouse gas results in warming of the lower atmosphere at the surface (called the troposphere) but cooling of the upper atmosphere (called the stratosphere). Depletion of the ozone layer by chemical refrigerants has also resulted in a cooling effect in the stratosphere. If the Sun was responsible for observed warming, warming of the troposphere at the surface and warming at the top of the stratosphere would be expected as increase solar activity would replenish ozone and oxides of nitrogen. The stratosphere has a reverse temperature gradient than the troposphere so as the temperature of the troposphere cools with altitude, the stratosphere rises with altitude. Hadley cells are the mechanism by which equatorial generated ozone in the tropics (highest area of UV irradiance in the stratosphere) is moved poleward. Global climate models suggest that climate change may widen the Hadley cells and push the jetstream northward thereby expanding the tropics region and resulting in warmer, dryer conditions in those areas overall. Non-consensus views Habibullo Abdussamatov (2004), head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, has argued that the Sun is responsible for recently observed climate change. Journalists for news sources canada.com (Solomon, 2007b), National Geographic News (Ravilious, 2007), and LiveScience (Than, 2007) reported on the story of warming on Mars. In these articles, Abdussamatov was quoted. He stated that warming on Mars was evidence that global warming on Earth was being caused by changes in the Sun. Ravilious (2007) quoted two scientists who disagreed with Abdussamatov: Amato Evan, a climate scientist at the University of Wisconsin–Madison, in the US, and Colin Wilson, a planetary physicist at Oxford University in the UK. According to Wilson, "Wobbles in the orbit of Mars are the main cause of its climate change in the current era" (see also orbital forcing). Than (2007) quoted Charles Long, a climate physicist at Pacific Northwest National Laboratories in the US, who disagreed with Abdussamatov. Than (2007) pointed to the view of Benny Peiser, a social anthropologist at Liverpool John Moores University in the UK. In his newsletter, Peiser had cited a blog that had commented on warming observed on several planetary bodies in the Solar System. These included Neptune's moon Triton, Jupiter, Pluto and Mars. In an e-mail interview with Than (2007), Peiser stated that:"I think it is an intriguing coincidence that warming trends have been observed on a number of very diverse planetary bodies in our solar system, (...) Perhaps this is just a fluke."Than (2007) provided alternative explanations of why warming had occurred on Triton, Pluto, Jupiter and Mars. The US Environmental Protection Agency (US EPA, 2009) responded to public comments on climate change attribution. A number of commenters had argued that recent climate change could be attributed to changes in solar irradiance. According to the US EPA (2009), this attribution was not supported by the bulk of the scientific literature. Citing the work of the IPCC (2007), the US EPA pointed to the low contribution of solar irradiance to radiative forcing since the start of the Industrial Revolution in 1750. Over this time period (1750 to 2005), the estimated contribution of solar irradiance to radiative forcing was 5% the value of the combined radiative forcing due to increases in the atmospheric concentrations of carbon dioxide, methane and nitrous oxide (see graph opposite). Effect of cosmic rays Henrik Svensmark has suggested that the magnetic activity of the sun deflects cosmic rays, and that this may influence the generation of cloud condensation nuclei, and thereby have an effect on the climate. The website ScienceDaily reported on a 2009 study that looked at how past changes in climate have been affected by the Earth's magnetic field. Geophysicist Mads Faurschou Knudsen, who co-authored the study, stated that the study's results supported Svensmark's theory. The authors of the study also acknowledged that plays an important role in climate change. Consensus view on cosmic rays The view that cosmic rays could provide the mechanism by which changes in solar activity affect climate is not supported by the literature. Solomon et al. (2007) state:[..] the cosmic ray time series does not appear to correspond to global total cloud cover after 1991 or to global low-level cloud cover after 1994. Together with the lack of a proven physical mechanism and the plausibility of other causal factors affecting changes in cloud cover, this makes the association between galactic cosmic ray-induced changes in aerosol and cloud formation controversial Studies by Lockwood and Fröhlich (2007) and Sloan and Wolfendale (2008) found no relation between warming in recent decades and cosmic rays. Pierce and Adams (2009) used a model to simulate the effect of cosmic rays on cloud properties. They concluded that the hypothesized effect of cosmic rays was too small to explain recent climate change. Pierce and Adams (2009) noted that their findings did not rule out a possible connection between cosmic rays and climate change, and recommended further research. Erlykin et al. (2009) found that the evidence showed that connections between solar variation and climate were more likely to be mediated by direct variation of insolation rather than cosmic rays, and concluded: "Hence within our assumptions, the effect of varying solar activity, either by direct solar irradiance or by varying cosmic ray rates, must be less than 0.07 °C since 1956, i.e. less than 14% of the observed global warming." Carslaw (2009) and Pittock (2009) review the recent and historical literature in this field and continue to find that the link between cosmic rays and climate is tenuous, though they encourage continued research. US EPA (2009) commented on research by Duplissy et al. (2009):The CLOUD experiments at CERN are interesting research but do not provide conclusive evidence that cosmic rays can serve as a major source of cloud seeding. Preliminary results from the experiment (Duplissy et al., 2009) suggest that though there was some evidence of ion mediated nucleation, for most of the nucleation events observed the contribution of ion processes appeared to be minor. These experiments also showed the difficulty in maintaining sufficiently clean conditions and stable temperatures to prevent spurious aerosol bursts. There is no indication that the earlier Svensmark experiments could even have matched the controlled conditions of the CERN experiment. We find that the Svensmark results on cloud seeding have not yet been shown to be robust or sufficient to materially alter the conclusions of the assessment literature, especially given the abundance of recent literature that is skeptical of the cosmic ray-climate linkage See also Climate change adaptation Climate change denial Climate change mitigation Climate resilience Environmental effects of aviation Notes References , pp. 332–333.

Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori (Gracilaria) and "tengusa" (Gelidiaceae). Agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling. These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum. Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative; an appetite suppressant; a vegetarian substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and other desserts; as a clarifying agent in brewing; and for sizing paper and fabrics. Etymology The word "agar" comes from agar-agar, the Malay name for red algae (Gigartina, Gracilaria) from which the jelly is produced. It is also known as Kanten () (from the phrase kan-zarashi tokoroten () or “cold-exposed agar”), Japanese isinglass, China grass, Ceylon moss or Jaffna moss. Gracilaria lichenoides is specifically referred to as agal-agal or Ceylon agar. History Agar may have been discovered in Japan in 1658 by Mino Tarōzaemon (), an innkeeper in current Fushimi-ku, Kyoto who, according to legend, was said to have discarded surplus seaweed soup (Tokoroten) and noticed that it gelled later after a winter night's freezing. Over the following centuries, agar became a common gelling agent in several Southeast Asian cuisines. Agar was first subjected to chemical analysis in 1859 by the French chemist Anselme Payen, who had obtained agar from the marine algae Gelidium corneum. Beginning in the late 19th century, agar began to be used as a solid medium for growing various microbes. Agar was first described for use in microbiology in 1882 by the German microbiologist Walther Hesse, an assistant working in Robert Koch's laboratory, on the suggestion of his wife Fanny Hesse. Agar quickly supplanted gelatin as the base of microbiological media, due to its higher melting temperature, allowing microbes to be grown at higher temperatures without the media liquefying. With its newfound use in microbiology, agar production quickly increased. This production centered on Japan, which produced most of the world's agar until World War II. However, with the outbreak of World War II, many nations were forced to establish domestic agar industries in order to continue microbiological research. Around the time of World War II, approximately 2,500 tons of agar were produced annually. By the mid-1970s, production worldwide had increased dramatically to approximately 10,000 tons each year. Since then, production of agar has fluctuated due to unstable and sometimes over-utilized seaweed populations. Composition Agar consists of a mixture of two polysaccharides: agarose and agaropectin, with agarose making up about 70% of the mixture. Agarose is a linear polymer, made up of repeating units of agarobiose, a disaccharide made up of D-galactose and 3,6-anhydro-L-galactopyranose. Agaropectin is a heterogeneous mixture of smaller molecules that occur in lesser amounts, and is made up of alternating units of D-galactose and L-galactose heavily modified with acidic side-groups, such as sulfate and pyruvate. Agar exhibits hysteresis, solidifying at about 32–40 °C (305–313 K, 90–104 °F) but melting at 85 °C (358  K, 185 °F). This property lends a suitable balance between easy melting and good gel stability at relatively high temperatures. Since many scientific applications require incubation at temperatures close to human body temperature (37 °C), agar is more appropriate than other solidifying agents that melt at this temperature, such as gelatin. Uses Culinary Agar-agar is a natural vegetable gelatin counterpart. It is white and semi-translucent when sold in packages as washed and dried strips or in powdered form. It can be used to make jellies, puddings, and custards. When making jelly, it is boiled in water until the solids dissolve. Sweetener, flavoring, coloring, fruits and or vegetables are then added, and the liquid is poured into molds to be served as desserts and vegetable aspics or incorporated with other desserts such as a layer of jelly in a cake. Agar-agar is approximately 80% dietary fiber, so it can serve as an intestinal regulator. Its bulking quality has been behind fad diets in Asia, for example the kanten (the Japanese word for agar-agar) diet. Once ingested, kanten triples in size and absorbs water. This results in the consumers feeling fuller. This diet has recently received some press coverage in the United States as well. The diet has shown promise in obesity studies. Asian culinary One use of agar in Japanese cuisine (Wagashi) is anmitsu, a dessert made of small cubes of agar jelly and served in a bowl with various fruits or other ingredients. It is also the main ingredient in mizu yōkan, another popular Japanese food. In Philippine cuisine, it is used to make the jelly bars in the various gulaman refreshments like Sago't Gulaman, Samalamig, or desserts such as buko pandan, agar flan, halo-halo, fruit cocktail jelly, and the black and red gulaman used in various fruit salads. In Vietnamese cuisine, jellies made of flavored layers of agar agar, called thạch, are a popular dessert, and are often made in ornate molds for special occasions. In Indian cuisine, agar agar is used for making desserts. In Burmese cuisine, a sweet jelly known as kyauk kyaw is made from agar. Agar jelly is widely used in Taiwanese bubble tea. Other culinary It can be used as addition to or as a replacement for pectin in jams and marmalades, as a substitute to gelatin for its superior gelling properties, and as a strengthening ingredient in souffles and custards. Another use of agar-agar is in a Russian dish ptich'ye moloko (bird's milk), a rich jellified custard (or soft meringue) used as a cake filling or chocolate-glazed as individual sweets. Agar-agar may also be used as the gelling agent in gel clarification, a culinary technique used to clarify stocks, sauces, and other liquids. Mexico has traditional candies made out of Agar gelatin, most of them in colorful, half-circle shapes that resemble a melon or watermelon fruit slice, and commonly covered with sugar. They are known in Spanish as Dulce de Agar (Agar sweets) Agar-agar is an allowed nonorganic/nonsynthetic additive used as a thickener, gelling agent, texturizer, moisturizer, emulsifier, flavor enhancer, and absorbent in certified organic foods. Microbiology Agar plate An agar plate or Petri dish is used to provide a growth medium using a mix of agar and other nutrients in which microorganisms, including bacteria and fungi, can be cultured and observed under the microscope. Agar is indigestible for many organisms so that microbial growth does not affect the gel used and it remains stable. Agar is typically sold commercially as a powder that can be mixed with water and prepared similarly to gelatin before use as a growth medium. Other ingredients are added to the agar to meet the nutritional needs of the microbes. Many microbe-specific formulations are available because some microbes prefer certain environmental conditions over others. Agar is often dispensed using a sterile media dispenser. Motility assays As a gel, an agar or agarose medium is porous and therefore can be used to measure microorganism motility and mobility. The gel's porosity is directly related to the concentration of agarose in the medium, so various levels of effective viscosity (from the cell's "point of view") can be selected, depending on the experimental objectives. A common identification assay involves culturing a sample of the organism deep within a block of nutrient agar. Cells will attempt to grow within the gel structure. Motile species will be able to migrate, albeit slowly, throughout the gel, and infiltration rates can then be visualized, whereas non-motile species will show growth only along the now-empty path introduced by the invasive initial sample deposition. Another setup commonly used for measuring chemotaxis and chemokinesis utilizes the under-agarose cell migration assay, whereby a layer of agarose gel is placed between a cell population and a chemoattractant. As a concentration gradient develops from the diffusion of the chemoattractant into the gel, various cell populations requiring different stimulation levels to migrate can then be visualized over time using microphotography as they tunnel upward through the gel against gravity along the gradient. Plant biology Research grade agar is used extensively in plant biology as it is optionally supplemented with a nutrient and/or vitamin mixture that allows for seedling germination in Petri dishes under sterile conditions (given that the seeds are sterilized as well). Nutrient and/or vitamin supplementation for Arabidopsis thaliana is standard across most experimental conditions. Murashige & Skoog (MS) nutrient mix and Gamborg's B5 vitamin mix in general are used. A 1.0% agar/0.44% MS+vitamin dH2O solution is suitable for growth media between normal growth temps. When using agar, within any growth medium, it is important to know that the solidification of the agar is pH-dependent. The optimal range for solidification is between 5.4 and 5.7. Usually, the application of potassium hydroxide is needed to increase the pH to this range. A general guideline is about 600 µl 0.1M KOH per 250 ml GM. This entire mixture can be sterilized using the liquid cycle of an autoclave. This medium nicely lends itself to the application of specific concentrations of phytohormones etc. to induce specific growth patterns in that one can easily prepare a solution containing the desired amount of hormone, add it to the known volume of GM, and autoclave to both sterilize and evaporate off any solvent that may have been used to dissolve the often-polar hormones. This hormone/GM solution can be spread across the surface of Petri dishes sown with germinated and/or etiolated seedlings. Experiments with the moss Physcomitrella patens, however, have shown that choice of the gelling agent – agar or Gelrite – does influence phytohormone sensitivity of the plant cell culture. Other uses Agar is used: As an impression material in dentistry. As a medium to precisely orient the tissue specimen and secure it by agar pre-embedding (especially useful for small endoscopy biopsy specimens) for histopathology processing To make salt bridges and gel plugs for use in electrochemistry. In formicariums as a transparent substitute for sand and a source of nutrition. As a natural ingredient in forming modeling clay for young children to play with. As an allowed biofertilizer component in organic farming. As a substrate for precipitin reactions in immunology. At different times as a substitute for gelatin in photographic emulsions, arrowroot in preparing silver paper and as a substitute for fish glue in resist etching. As an MRI elastic gel phantom to mimic tissue mechanical properties in Magnetic Resonance Elastography Gelidium agar is used primarily for bacteriological plates.

Bromeliales is an order of flowering plants. Such an order has been recognized by a few systems of plant taxonomy, with a various placement. It appears that it always has had the same circumscription: consisting only of the family Bromeliaceae, the bromeliad or pineapple family. The order is not recognized in the APG II system, of 2003, which places the plants involved in the order Poales. Some examples are: The Cronquist system of 1981 placed this order in subclass Zingiberidae, of class Liliopsida [=monocotyledons]. The Thorne system (1992) placed the order in superorder Commelinanae in subclass Liliidae [=monocotyledons]. The Dahlgren system placed the order in superorder Bromeliiflorae (also known as Bromelianae) in subclass Liliidae [=monocotyledons] together with five other orders. The Engler system, in its update of 1964, placed the order in class Monocotyledoneae. References ITIS 42329 Historically recognized angiosperm orders

The Government of Barbados (GoB), is a unitary parliamentary constitutional republic, where the President of Barbados represents as the head of state and the Prime Minister of Barbados represents as the head of government. The country has a bicameral legislature and a political party system, based on universal adult suffrage and fair elections. The Senate has 21 members, appointed by the Governor-General on behalf of the monarch, 12 on the advice of the Prime Minister, two on the advice of the Leader of the Opposition, and seven at the Governor-General's sole discretion. The House of Assembly has 30 members, all elected. Both houses debate all legislation. However, the House of Assembly may override Senate's rejection of money bills and other bills except bills amending the Constitution. Officers of each house (President and Deputy President of the Senate; Speaker, Deputy Speaker, and Chairman of Committees of the Assembly) are elected from the members of the respective houses. In keeping with the Westminster system of governance, Barbados has evolved into an independent parliamentary democracy, meaning that all political power rests with the Parliament under a non-political President as head of state. Executive authority is vested in the President, who normally acts only on the advice of the Prime Minister and Cabinet, who are collectively responsible to Parliament. Barbadian law is rooted in English common law, and the Constitution of Barbados implemented in 1966, is the supreme law of the land. Fundamental rights and freedoms of the individual are set out in the Constitution and are protected by a strict legal code. The Cabinet is headed by the Prime Minister, who must be an elected member of Parliament, and other ministers are appointed from either chamber by the Governor-General, as advised by the Prime Minister. The President appoints as Leader of the Opposition the member of House of Assembly who commands the support of the largest number of members of that House in opposition to the ruling party's government. The maximum duration of a Parliament is five years from the first sitting. There is a simultaneous dissolution of both Houses of Parliament by the President, acting on the advice of the Prime Minister. There is an established non-political civil service. Also, there are separate constitutional commissions for the Judicial and Legal Service, the Public Service, and the Police Service. History The government has been chosen by elections since 1961 elections, when Barbados achieved full self-governance. Before then, the government was a Crown colony consisting of either colonial administration solely (such as the Executive Council), or a mixture of colonial rule and a partially elected assembly, such as the Legislative Council. Since independence the Democratic Labour Party (DLP) held office 1966 to 1976, from 1986 to 1994, and from January 2008 to 2018. The Barbados Labour Party (BLP) governed from 1976 to 1986, from September 1994–2008 and has formed the government from 2018–Present. Executive branch The Executive Branch of government conducts the ordinary business of government. These functions are called out by the Prime Minister and cabinet ministers. The prime minister chooses the ministers of government they wish to have in the cabinet but they are actually appointed by the President. Heads of State President Head of Government Prime Ministers Premier (Abolished) Attorney General's Ministers List of Government Ministries, Ministers and Permanent Secretaries Legislative Branch Under Barbados' version of the Westminster system of government, the executive and legislative branches are partly intertwined. The only official Cabinet office (other than Prime Minister) expressly mentioned in the Constitution of Barbados is Office of the Attorney-General. President Chief Secretaries (Abolished) Auditors-General Senators Presidents of the Senate Members of the House ( a/k/a Members of Parliament) Speakers of the House of Assembly Clerks of Parliament Law The Constitution of Barbados is the supreme law of the nation. The Attorney General heads the independent judiciary. Historically, Barbadian law was based entirely on English common law with a few local adaptations. At the time of independence, the Parliament of the United Kingdom lost its ability to legislate for Barbados, but the existing English and British common law and statutes in force at that time, together with other measures already adopted by the Barbadian Parliament, became the basis of the new country's legal system. Legislation may be shaped or influenced by such organisations as the United Nations, the Organization of American States, or other international bodies to which Barbados has obligatory commitments by treaty. Additionally, through international co-operation, other institutions may supply the Barbados Parliament with key sample legislation to be adapted to meet local circumstances before enacting it as local law. New acts are passed by the Barbadian Parliament and require approval by the President to become law. The President, has the power to "withhold assent" from laws by vetoing the proposed law without parliamentary override. Judicial branch The judiciary is the legal system through which punishments are handed out to individuals who break the law. The functions of the judiciary are to enforce laws; to interpret laws; to conduct court hearings; to hear court appeals. The local court system of Barbados is made up of: Magistrates' Courts: Covering Criminal, Civil, Domestic, Domestic Violence, and Juvenile matters. But can also take up matters dealing with Coroner's Inquests, Liquor Licences, and civil marriages. Further, the Magistrates' Courts deal with Contract and Tort law where claims do not exceed $10,000.00. The Supreme Court: is made up of High Court and Court of Appeals. High Court: Consisting of Civil, Criminal, and Family law divisions. Court of Appeal: Handles appeals from the High Court and Magistrates' Court. It hears appeals in both the civil, and criminal law jurisdictions. It may consist of a single Justice of Appeal sitting in Chambers; or may sit as a Full Court of three Justices of Appeals. The Caribbean Court of Justice (CCJ), (based in Port of Spain, Trinidad and Tobago), is the court of last resort (final jurisdiction) over Barbadian law. It replaced the London-based Judicial Committee of the Privy Council (JCPC). The CCJ may resolve other disputed matters dealing with the Caribbean Single Market and Economy (CSME). Chief Justices Justices of Appeals Magistrates Perception Transparency International ranked Barbados as 17th place (of 179) in the world on its Corruption Perceptions Index in 2010, with only one nation scoring better in the Americas.

Transport infrastructure in Brazil is characterized by strong regional differences and lack of development of the national rail network. Brazil's fast-growing economy, and especially the growth in exports, will place increasing demands on the transport networks. However, sizeable new investments that are expected to address some of the issues are either planned or in progress. It is common to travel domestically by air because the price is low. Brazil has the second highest number of airports in the world, after the USA. Railways The Brazilian railway network has an extension of about . It is basically used for transporting ores. Usually, the railway sector was treated in a secondary way in Brazil, due to logistical, economic or political difficulties to install more railways. The Brazilian railroad system had a great expansion between 1875 and 1920. The heyday of the railway modal was interrupted during the Getúlio Vargas government, which prioritized the road modal. In the 1940s, the railway network was already facing several problems, from low-powered locomotives to uneconomical layouts. In 1957, a state-owned company was created, the National Railroad Network (RFFSA), which started to manage 18 railroads in the Union. Several deficit railways were closed under the promise of state investment in new projects, which did not happen. The actions were centralized in the government until the opening of the market in 1990. So, the National Privatization Plan was instituted, with dozens of concessions being made. However, they ended up concentrating the railways, mainly, in three large business groups, América Latina Logística (ALL), Vale S.A. and MRS Logística. The refurbishment generated an increase in productivity (cargoes transported increased by 30% with the same railway line). However, the main problem was that the reform not only gave away the railway line, but also geographical exclusivity. This resulted in the non-creation of competitive incentives for the expansion and renewal of the existing network. With the State maintaining the opening of new railways a difficult, slow and bureaucratic process, as it maintains the total monopoly of power over this sector, the railways did not expand any further in the country, and the sector was very outdated. In 2021, a New Framework for Railways was created, allowing the construction of railways by authorization, as occurs in the exploration of infrastructure in sectors such as telecommunications, electricity and ports. It's also possible to authorize the exploration of stretches not implemented, idle, or in the process of being returned or deactivated. With the change of rules in the sector, in December 2021, there were already requests to open of new tracks, in 64 requests for implementation of new railways. Nine new railroads had already been authorized by the Federal Government, in of new tracks. Total actual network: 29,888 km of railroad and 1,411 km of subway and light rail Broad gauge: 4,932 km gauge (939 km electrified) Narrow gauge: 23,341 km gauge (24 km electrified) Dual gauge: 396 km 1000 mm and 1600 mm gauges (three rails) Standard gauge: 194 km gauge (2014) Estrada de Ferro do Amapá in the middle of the Amazon Rainforest also used standard gauge. A 12 km section of the former gauge Estrada de Ferro Oeste de Minas is retained as a heritage railway. Cities with metros and light rail transit (combined) Railway links with adjacent countries International rail links exist between Brazil and Argentina, Bolivia and Uruguay. Tramways Brazil had a hundred tramway systems. Currently, there are vintage tramways operating in Belém, Campinas, Campos do Jordão, Itatinga, Rio de Janeiro and Santos. Highways Brazil has more than of roads, of which are paved (12,4%), and about are divided highways. The total of paved roads increased from 35,496 km (22,056 mi) in 1967 to 215,000 km (133,595 mi) in 2018. The two most important highways in the country are BR-101 and BR-116. Although Brazil has the largest duplicated road network in Latin America, it's considered insufficient for the country's needs: in 2021, it was calculated that the ideal amount of duplicated roads would be something around from to . The main road axes also have problems because they often have inadequate geometry and constructive characteristics that don't allow quality long-distance flow (non-interference from local traffic and high speed). The Brazilian Federal Government has never implemented a National Highway Plan at the same level as developed countries such as the USA, Japan or European countries, which specifically aimed at inter-regional travel, and which should preferably be served by highways (which would differ from the common duplicated highways by geometric pattern, access control without access to neighboring lots, zero level crossings and returns, prohibition of circulation of non-motorized vehicles such as cyclists, animal traction or human propulsion, as per the Vienna Convention). The Brazilian State, despite some planning efforts, has been guided by a reactive action to the increase in demand (only duplicating some roads with old and inadequate layout) and not by a purposeful vision, directing occupation and economic density in the territory. Another problem is the lack of directing the Union Budget towards infrastructure works: in Brazil there is no law that guarantees funds from the Federal Budget for works on highways and other modes of transport (unlike what happens in sectors such as Education and Health), depending exclusively on the goodwill of the rulers. In the US, for example, the gasoline tax can only be used for transport infrastructure works. Brazil even invested 1.5% of the country's budget in infrastructure in the 1970s, being the time when the most investment was made in highways; but in the 1990s, only 0.1% of the budget was invested in this sector, maintaining an average of 0.5% in the 2000s and 2010, insufficient amounts for the construction of an adequate road network. For comparative purposes, the average investment of the USA and the European Union was 1% between 1995 and 2013, even though they already have a much more advanced road infrastructure than Brazil. The country has a medium rate of car ownership of 471 per 1000 people, however in comparison to the other developing economies of the BRIC group Brazil exceeds India and China. The country still has several states where paved access to 100% of the state's municipalities has not yet been reached. Some states have 100% of cities with asphalt access, such as Santa Catarina, which reached this goal in 2014; Paraíba, which reached this goal in 2017, and Alagoas, which reached this goal in 2021 In states like Rio Grande do Sul, in 2020, there were still 54 cities without asphalt access. In Paraná, in 2021, there were still 4 cities without asphalt access. In Minas Gerais, in 2016, there were still 5 cities without asphalt access. Waterways 50,000 km navigable (most in areas remote from industry or population) (2012) Among the main Brazilian waterways, two stand out: Hidrovia Tietê-Paraná (which has a length of 2,400 km, 1,600 on the Paraná River and 800 km on the Tietê River, draining agricultural production from the states of Mato Grosso, Mato Grosso do Sul, Goiás and part of Rondônia, Tocantins and Minas Gerais) and Hidrovia do Solimões-Amazonas (it has two sections: Solimões, which extends from Tabatinga to Manaus, with approximately 1600 km, and Amazonas, which extends from Manaus to Belém, with 1650 km. Almost entirely passenger transport from the Amazon plain is done by this waterway, in addition to practically all cargo transportation that is directed to the major regional centers of Belém and Manaus). In Brazil, this transport is still underutilized: the most important waterway stretches, from an economic point of view, are found in the Southeast and South of the country. Its full use still depends on the construction of locks, major dredging works and, mainly, of ports that allow intermodal integration. Pipelines condensate/gas 62 km natural gas 11,696 km (1,165 km distribution, 4,794 km transport) liquid petroleum gas 353 km (37 km distribution, 40 km transport) crude oil 4,517 km (1,985 km distribution) refined products 5,959 km (1,165 km distribution, 4,794 km transport) Seaports and harbors The busiest port in the country, and the 2nd busiest in all of Latin America, losing only to the Port of Colón, is the Port of Santos.

William Henry Gates III (born October 28, 1955) is an American business magnate, software developer, investor, author, and philanthropist. He is a co-founder of Microsoft, along with his late childhood friend Paul Allen. During his career at Microsoft, Gates held the positions of chairman, chief executive officer (CEO), president and chief software architect, while also being the largest individual shareholder until May 2014. He was a major entrepreneur of the microcomputer revolution of the 1970s and 1980s. Gates was born and raised in Seattle, Washington. In 1975, he and Allen founded Microsoft in Albuquerque, New Mexico. It became the world's largest personal computer software company. Gates led the company as chairman and CEO until stepping down as CEO in January 2000, succeeded by Steve Ballmer, but he remained chairman of the board of directors and became chief software architect. During the late 1990s, he was criticized for his business tactics, which have been considered anti-competitive. This opinion has been upheld by numerous court rulings. In June 2008, Gates transitioned to a part-time role at Microsoft and full-time work at the Bill & Melinda Gates Foundation, the private charitable foundation he and his then-wife, Melinda Gates, established in 2000. He stepped down as chairman of the board of Microsoft in February 2014 and assumed a new post as technology adviser to support the newly appointed CEO Satya Nadella. In March 2020, Gates left his board positions at Microsoft and Berkshire Hathaway to focus on his philanthropic efforts including climate change, global health and development, and education. Since 1987, Gates has been included in the Forbes list of the world's wealthiest people. From 1995 to 2017, he held the Forbes title of the richest person in the world every year except from 2010 to 2013. In October 2017, he was surpassed by Amazon founder and CEO Jeff Bezos, who had an estimated net worth of US$90.6 billion compared to Gates's net worth of US$89.9 billion at the time. As of February 2022, Gates had an estimated net worth of US$130 billion, making him the fourth-richest person in the world. Later in his career and since leaving day-to-day operations at Microsoft in 2008, Gates has pursued many business and philanthropic endeavors. He is the founder and chairman of several companies, including BEN, Cascade Investment, bgC3, and TerraPower. He has given sizable amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, reported to be the world's largest private charity. Through the foundation, he led an early 21st century vaccination campaign that significantly contributed to the eradication of the wild poliovirus in Africa. In 2010, Gates and Warren Buffett founded The Giving Pledge, whereby they and other billionaires pledge to give at least half of their wealth to philanthropy. Early life Bill Gates was born in Seattle, Washington on October 28, 1955. He is the son of William H. Gates Sr. (1925–2020) and Mary Maxwell Gates (1929–1994). His ancestry includes English, German, and Irish/Scots-Irish. His father was a prominent lawyer, and his mother served on the board of directors for First Interstate BancSystem and the United Way of America. Gates's maternal grandfather was J. W. Maxwell, a national bank president. Gates has an older sister Kristi (Kristianne) and a younger sister Libby. He is the fourth of his name in his family but is known as William Gates III or "Trey" (i.e., three) because his father had the "II" suffix. The family lived in the Sand Point area of Seattle in a home that was damaged by a rare tornado when Gates was seven years old. Early in his life, Gates observed that his parents wanted him to pursue a law career. When he was young, his family regularly attended a church of the Congregational Christian Churches, a Protestant Reformed denomination. Gates was small for his age and was bullied as a child. The family encouraged competition; one visitor reported that "it didn't matter whether it was hearts or pickleball or swimming to the dock; there was always a reward for winning and there was always a penalty for losing". At 13, he enrolled in the private Lakeside prep school, where he wrote his first software program. When he was in the eighth grade, the Mothers' Club at the school used proceeds from Lakeside School's rummage sale to buy a Teletype Model 33 ASR terminal and a block of computer time on a General Electric (GE) computer for the students. Gates took an interest in programming the GE system in BASIC, and he was excused from math classes to pursue his interest. He wrote his first computer program on this machine, an implementation of tic-tac-toe that allowed users to play games against the computer. Gates was fascinated by the machine and how it would always execute software code perfectly. After the Mothers Club donation was exhausted, Gates and other students sought time on systems including DEC PDP minicomputers. One of these systems was a PDP-10 belonging to Computer Center Corporation (CCC) which banned Gates, Paul Allen, Ric Weiland, and Gates's best friend and first business partner Kent Evans, for the summer after it caught them exploiting bugs in the operating system to obtain free computer time. The four students formed the Lakeside Programmers Club to make money. At the end of the ban, they offered to find bugs in CCC's software in exchange for extra computer time. Rather than using the system remotely via Teletype, Gates went to CCC's offices and studied source code for various programs that ran on the system, including Fortran, Lisp, and machine language. The arrangement with CCC continued until 1970 when the company went out of business. The following year, a Lakeside teacher enlisted Gates and Evans to automate the school's class-scheduling system, providing them computer time and royalties in return. The duo worked diligently in order to have the program ready for their senior year. Towards the end of their junior year, Evans was killed in a mountain climbing accident, which Gates has described as one of the saddest days of his life. Gates then turned to Allen who helped him finish the system for Lakeside. At 17, Gates formed a venture with Allen called Traf-O-Data to make traffic counters based on the Intel 8008 processor. In 1972, he served as a congressional page in the House of Representatives. He was a National Merit Scholar when he graduated from Lakeside School in 1973. He scored 1590 out of 1600 on the Scholastic Aptitude Tests (SAT) and enrolled at Harvard College in the autumn of 1973. He chose a pre-law major but took mathematics and graduate level computer science courses. While at Harvard, he met fellow student Steve Ballmer. Gates left Harvard after two years while Ballmer stayed and graduated magna cum laude. Years later, Ballmer succeeded Gates as Microsoft's CEO and maintained that position from 2000 until his resignation in 2014. Gates devised an algorithm for pancake sorting as a solution to one of a series of unsolved problems presented in a combinatorics class by professor Harry Lewis. His solution held the record as the fastest version for over 30 years, and its successor is faster by only 2%. His solution was formalized and published in collaboration with Harvard computer scientist Christos Papadimitriou. Gates remained in contact with Paul Allen and joined him at Honeywell during the summer of 1974. In 1975, the MITS Altair 8800 was released based on the Intel 8080 CPU, and Gates and Allen saw the opportunity to start their own computer software company. Gates dropped out of Harvard that same year. His parents were supportive of him after seeing how much he wanted to start his own company. He explained his decision to leave Harvard: "if things hadn't worked out, I could always go back to school. I was officially on leave." Microsoft BASIC Gates read the January 1975 issue of Popular Electronics which demonstrated the Altair 8800, and he contacted Micro Instrumentation and Telemetry Systems (MITS) to inform them that he and others were working on a BASIC interpreter for the platform. In reality, Gates and Allen did not have an Altair and had not written code for it; they merely wanted to gauge MITS's interest. MITS president Ed Roberts agreed to meet them for a demonstration, and over the course of a few weeks they developed an Altair emulator that ran on a minicomputer, and then the BASIC interpreter. The demonstration was held at MITS's offices in Albuquerque, New Mexico; it was a success and resulted in a deal with MITS to distribute the interpreter as Altair BASIC. MITS hired Allen, and Gates took a leave of absence from Harvard to work with him at MITS in November 1975. Allen named their partnership "Micro-Soft", a combination of "microcomputer" and "software", and their first office was in Albuquerque. The first employee Gates and Allen hired was their high school collaborator Ric Weiland. They dropped the hyphen within a year and officially registered the trade name "Microsoft" with the Secretary of the State of New Mexico on November 26, 1976. Gates never returned to Harvard to complete his studies. Microsoft's Altair BASIC was popular with computer hobbyists, but Gates discovered that a pre-market copy had leaked out and was being widely copied and distributed. In February 1976, he wrote an Open Letter to Hobbyists in the MITS newsletter in which he asserted that more than 90% of the users of Microsoft Altair BASIC had not paid Microsoft for it and the Altair "hobby market" was in danger of eliminating the incentive for any professional developers to produce, distribute, and maintain high-quality software. This letter was unpopular with many computer hobbyists, but Gates persisted in his belief that software developers should be able to demand payment. Microsoft became independent of MITS in late 1976, and it continued to develop programming language software for various systems. The company moved from Albuquerque to Bellevue, Washington on January 1, 1979. Gates said he personally reviewed and often rewrote every line of code that the company produced in its first five years. As the company grew, he transitioned into a manager role, then an executive. DONKEY.BAS, is a computer game written in 1981 and included with early versions of the PC DOS operating system distributed with the original IBM PC. It is a driving game in which the player must avoid hitting donkeys. The game was written by Gates and Neil Konzen. IBM partnership IBM, the leading supplier of computer equipment to commercial enterprises at the time, approached Microsoft in July 1980 concerning software for its upcoming personal computer, the IBM PC, after Bill Gates's mother, Mary Maxwell Gates, mentioned Microsoft to John Opel, IBM's CEO. IBM first proposed that Microsoft write the BASIC interpreter. IBM's representatives also mentioned that they needed an operating system, and Gates referred them to Digital Research (DRI), makers of the widely used CP/M operating system. IBM's discussions with Digital Research went poorly, however, and they did not reach a licensing agreement. IBM representative Jack Sams mentioned the licensing difficulties during a subsequent meeting with Gates and asked if Microsoft could provide an operating system. A few weeks later, Gates and Allen proposed using 86-DOS, an operating system similar to CP/M, that Tim Paterson of Seattle Computer Products (SCP) had made for hardware similar to the PC. Microsoft made a deal with SCP to be the exclusive licensing agent of 86-DOS, and later the full owner. Microsoft employed Paterson to adapt the operating system for the PC and delivered it to IBM as PC DOS for a one-time fee of $50,000. The contract itself only earned Microsoft a relatively small fee. It was the prestige brought to Microsoft by IBM's adoption of their operating system that would be the origin of Microsoft's transformation from a small business to the leading software company in the world. Gates had not offered to transfer the copyright on the operating system to IBM because he believed that other personal computer makers would clone IBM's PC hardware. They did, making the IBM-compatible PC, running DOS, a de facto standard. The sales of MS-DOS (the version of DOS sold to customers other than IBM) made Microsoft a major player in the industry. The press quickly identified Microsoft as being very influential on the IBM PC. PC Magazine asked if Gates was "the man behind the machine?". Gates oversaw Microsoft's company restructuring on June 25, 1981, which re-incorporated the company in Washington state and made Gates the president and chairman of the board, with Paul Allen as vice president and vice chairman. In early 1983, Allen left the company after receiving a Hodgkin lymphoma diagnosis, effectively ending the formal business partnership between Gates and Allen, which had been strained months prior due to a contentious dispute over Microsoft equity. Later in the decade, Gates repaired his relationship with Allen and together the two donated millions to their childhood school Lakeside. They remained friends until Allen's death in October 2018. Windows Microsoft and Gates launched their first retail version of Microsoft Windows on November 20, 1985, in an attempt to fend off competition from Apple's Macintosh GUI, which had bewitched consumers with its simplicity and ease of use. In August of the following year, the company struck a deal with IBM to develop a separate operating system called OS/2. Although the two companies successfully developed the first version of the new system, the partnership deteriorated due to mounting creative differences. The operating system grew out of DOS in an organic fashion over a decade, until with Windows 95 the DOS text screen was relegated to the closet. Windows XP, released one year after Gates stepped down as Microsoft CEO, reportedly was the first to not be based on DOS. Windows 8.1 was the last version of the OS released before Gates left the chair of the firm to John W. Thompson on February 5, 2014. As of 2021, the latest release of the OS is known as Windows 11. Management style Gates had primary responsibility for Microsoft's product strategy from the company's founding from 1975 until 2006. He gained a reputation for being distant from others; an industry executive complained in 1981 that "Gates is notorious for not being reachable by phone and for not returning phone calls." An Atari executive recalled that he showed Gates a game and defeated him 35 of 37 times. When they met again a month later, Gates "won or tied every game. He had studied the game until he solved it. That is a competitor". In the early 1980s, while business partner Paul Allen was undergoing treatments for cancer, Gates — according to Allen — conspired to reduce Allen's share in Microsoft by issuing himself stock options. In his autobiography, Allen would later recall that Gates was "scheming to rip me off. It was mercenary opportunism plain and simple". Gates says he remembers the episode differently. Allen would also recall that Gates was prone to shouting episodes. Gates met regularly with Microsoft's senior managers and program managers, and the managers described him as being verbally combative. He also berated them for perceived holes in their business strategies or proposals that placed the company's long-term interests at risk. He interrupted presentations with such comments as "that's the stupidest thing I've ever heard" and "why don't you just give up your options and join the Peace Corps?" The target of his outburst would then have to defend the proposal in detail until Gates was fully convinced. When subordinates appeared to be procrastinating, he was known to remark sarcastically, "I'll do it over the weekend." Gates has been accused of bullying Microsoft employees. During Microsoft's early years, Gates was an active software developer, particularly in the company's programming language products, but his primary role in most of the company's history was as a manager and executive. He has not officially been on a development team since working on the TRS-80 Model 100, but he wrote code that shipped with the company's products as late as 1989. Jerry Pournelle wrote in 1985 when Gates announced Microsoft Excel: "Bill Gates likes the program, not because it's going to make him a lot of money (although I'm sure it will do that), but because it's a neat hack." On June 15, 2006, Gates announced that he would transition out of his role at Microsoft to dedicate more time to philanthropy. He gradually divided his responsibilities between two successors when he placed Ray Ozzie in charge of management and Craig Mundie in charge of long-term product strategy. The process took two years to fully transfer his duties to Ozzie and Mundie, and was completed on June 27, 2008. Antitrust litigation Gates approved of many decisions that led to antitrust litigation over Microsoft's business practices. In the 1998 United States v. Microsoft case, Gates gave deposition testimony that several journalists characterized as evasive. He argued with examiner David Boies over the contextual meaning of words such as "compete", "concerned", and "we". Later in the year, when portions of the videotaped deposition were played back in court, the judge was seen laughing and shaking his head. BusinessWeek reported: Gates later said that he had simply resisted attempts by Boies to mischaracterize his words and actions. "Did I fence with Boies? ... I plead guilty ... rudeness to Boies in the first degree." Despite Gates's denials, the judge ruled that Microsoft had committed monopolization, tying and blocking competition, each in violation of the Sherman Antitrust Act. Post-Microsoft Since leaving day-to-day operations at Microsoft, Gates has continued his philanthropy and works on other projects. According to the Bloomberg Billionaires Index, Gates was the world's highest-earning billionaire in 2013, as his net worth increased by US$15.8 billion to US$78.5 billion. , most of Gates's assets are held in Cascade Investment LLC, an entity through which he owns stakes in numerous businesses, including Four Seasons Hotels and Resorts, and Corbis Corp. On February 4, 2014, Gates stepped down as chairman of Microsoft to become "technology advisor" at the firm, alongside CEO Satya Nadella. Gates provided his perspective on a range of issues in a substantial interview that was published in the March 27, 2014, issue of Rolling Stone magazine. In the interview, Gates provided his perspective on climate change, his charitable activities, various tech companies and people involved in them, and the state of America. In response to a question about his greatest fear when he looks 50 years into the future, Gates stated: "there'll be some really bad things that'll happen in the next 50 or 100 years, but hopefully none of them on the scale of, say, a million people that you didn't expect to die from a pandemic, or nuclear or bioterrorism." Gates also identified innovation as the "real driver of progress" and pronounced that "America's way better today than it's ever been." Gates has expressed concern about the potential harms of superintelligence; in a Reddit "ask me anything", he stated that: In an interview that was held at the TED conference in March 2015, with Baidu's CEO, Robin Li, Gates said he would "highly recommend" Nick Bostrom's recent work, Superintelligence: Paths, Dangers, Strategies. During the conference, Gates warned that the world was not prepared for the next pandemic, a situation that would come to pass in late 2019 when the COVID-19 pandemic began. In March 2018, Gates met at his home in Seattle with Mohammed bin Salman, the reformist crown prince and de facto ruler of Saudi Arabia to discuss investment opportunities for Saudi Vision 2030. In June 2019, Gates admitted that losing the mobile operating system race to Android was his biggest mistake. He stated that it was within their skill set of being the dominant player, but partially blames the antitrust litigation during the time. That same year, Gates became an advisory board member of the Bloomberg New Economy Forum. On March 13, 2020, Microsoft announced Gates would be leaving his board positions at Berkshire Hathaway and Microsoft to dedicate his efforts in philanthropic endeavors such as climate change, global health and development, and education. During the COVID-19 pandemic, Gates has widely been looked at by media outlets as an expert on the issue, despite him not being a public official or having any prior medical training. His foundation did, however, establish the COVID-19 Therapeutics Accelerator in 2020 to hasten the development and evaluation of new and repurposed drugs and biologics to treat patients for COVID-19, and, as of February 2021, Gates expressed that he and Anthony Fauci frequently talk and collaborate on matters including vaccines and other medical innovations to fight the pandemic. Business ventures and investments (partial list) Gates has a multi-billion dollar investment portfolio with stake in various sectors and has participated in several entrepreneurial ventures beyond Microsoft, including: AutoNation, automotive retailer that Gates has a 16% stake in trading on the NYSE. bgC3 LLC, a think-tank and research company founded by Gates. Canadian National Railway (CN), a Canadian Class I freight railway. As of 2019, Gates is the largest single shareholder of CN stock. Cascade Investment LLC, a private investment and holding company incorporated in the United States, founded and controlled by Gates and headquartered in Kirkland, Washington. Gates is the top private owner of farmland in the United States with landholdings owned via Cascade Investment totalling 242,000 acres across 19 states. He is the 49th largest private owner of land in the US. Carbon Engineering, a for-profit venture founded by David Keith, which Gates helped fund. It's is also supported by Chevron Corporation and Occidental Petroleum. SCoPEx, Keith's academic venture in "sun-dimming" geoengineering, which Gates provided most of the $12 million for. Corbis (originally named Interactive Home Systems and now known as Branded Entertainment Network), a digital image licensing and rights services company founded and chaired by Gates. EarthNow, Seattle-based startup company aiming to blanket the Earth with live satellite video coverage. Gates is a large financial backer. Eclipse Aviation, a defunct manufacturer of very light jets. Gates was a major stake-holder early on in the project. Impossible Foods, a company that develops plant-based substitutes for meat products. Some of the $396 million Patrick O. Brown collected for his business came from Gates around 2014 to 2017. Ecolab, global provider of water, hygiene and energy technologies and services to the food, energy, healthcare, industrial and hospitality markets. Combined with the shares owned by the Foundation, Gates owns 11.6% of the company. A shareholder agreement in 2012 allowed him to own up to 25% of the company, but this agreement was removed. ResearchGate, a social networking site for scientists. Gates participated in a $35 million round of financing along with other investors. TerraPower, a nuclear reactor design company co-founded and chaired by Gates, which is developing next generation traveling-wave reactor nuclear power plants in an effort to tackle climate change. Breakthrough Energy Ventures, a closed fund for wealthy individuals who seek ROI on a 20-year horizon (see next section), which "is funding green start-ups and a host of other low-carbon entrepreneurial projects, including everything from advanced nuclear technology to synthetic breast milk." It was founded by Gates in 2015. Ginkgo Bioworks, a biotech startup that received $350 million in venture funding in 2019, in part from Gates's investment firm Cascade Investment. Luminous Computing, a company that develops neuromorphic photonic integrated circuits for AI acceleration. Mologic, British diagnostic technology company that Gates purchased, along with the Soros Economic Development Fund, "which has developed 10-minute Covid lateral flow tests that it aims to make for as little as $1." Climate change and energy Gates considers climate change and global access to energy to be critical, interrelated issues. He has urged governments and the private sector to invest in research and development to make clean, reliable energy cheaper. Gates envisions that a breakthrough innovation in sustainable energy technology could drive down both greenhouse gas emissions and poverty, and bring economic benefits by stabilizing energy prices. In 2011, he said: "If you gave me the choice between picking the next 10 presidents or ensuring that energy is environmentally friendly and a quarter as costly, I'd pick the energy thing." In 2015, he wrote about the challenge of transitioning the world's energy system from one based primarily on fossil fuels to one based on sustainable energy sources. Global energy transitions have historically taken decades. He wrote, "I believe we can make this transition faster, both because the pace of innovation is accelerating, and because we have never had such an urgent reason to move from one source of energy to another." This rapid transition, according to Gates, would depend on increased government funding for basic research and financially risky private-sector investment, to enable innovation in diverse areas such as nuclear energy, grid energy storage to facilitate greater use of solar and wind energy, and solar fuels. Gates spearheaded two initiatives that he announced at the 2015 United Nations Climate Change Conference in Paris. One was Mission Innovation, in which 20 national governments pledged to double their spending on research and development for carbon-free energy in over five years' time. Another initiative was Breakthrough Energy, a group of investors who agreed to fund high-risk startups in clean energy technologies. Gates, who had already invested $1 billion of his own money in innovative energy startups, committed a further $1 billion to Breakthrough Energy. In December 2020, he called for the U.S. federal government to create institutes for clean energy research, analogous to the National Institutes of Health. Gates has also urged rich nations to shift to 100% synthetic beef industries to reduce greenhouse gas emissions from food production. Gates has been criticised for holding a large stake in Signature Aviation, a company that services emissions-intensive private jets. In 2019, he began to divest from fossil fuels. He does not expect divestment itself to have much practical impact, but says that if his efforts to provide alternatives were to fail, he would not want to personally benefit from an increase in fossil fuel stock prices. After he published his book How to Avoid a Climate Disaster, parts of the climate activist community criticized Gate's approach as technological solutionism. In June 2021, Gates's company TerraPower and Warren Buffett's PacifiCorp announced the first Sodium nuclear reactor in Wyoming. Wyoming Governor Mike Gordon hailed the project as a step toward carbon-negative nuclear power. Wyoming Senator John Barrasso also said that it could boost the state's once active uranium mining industry. Political positions Regulation of the software industry In 1998, Gates rejected the need for regulation of the software industry in testimony before the United States Senate. During the Federal Trade Commission's (FTC) investigation of Microsoft in the 1990s, Gates was reportedly upset at Commissioner Dennis Yao for "float[ing] a line of hypothetical questions suggesting possible curbs on Microsoft's growing monopoly power". According to one source:Gates was vexed. "He started by calling Yao's ideas socialistic," recalls a source familiar with the July 15 meeting, "and as he got angrier and angrier and louder and louder, he got into calling them Communistic. Donald Trump Facebook ban On February 18, 2021, after Facebook and Twitter had banned Donald Trump from their platforms as a result of the 2020 United States presidential election which led to the 2021 United States Capitol attack, Gates said a permanent ban of Trump "would be a shame" and would be an "extreme measure". He warned that it would cause "polarization" if users with different political views divide up among various social networks, and said: "I don't think banning somebody who actually did get a fair number of votes (in the presidential election) – well less than a majority – forever would be that good." Patents for COVID-19 vaccines In April 2021, during the COVID-19 pandemic, Gates was criticized for suggesting that pharmaceutical companies should hold onto patents for COVID-19 vaccines. The criticism came due to the possibility of this preventing poorer nations from obtaining adequate vaccines. Tara Van Ho of the University of Essex stated, "Gates speaks as if all the lives being lost in India are inevitable but eventually the West will help when in reality the US & UK are holding their feet on the neck of developing states by refusing to break [intellectual property rights] protections. It's disgusting." Bill Gates is opposed to the TRIPS waiver. Bloomberg News reported him as saying he argued that Oxford University should not give away the rights to its COVID-19 information, as it had announced, but instead sell it to a single industry partner, as it did. His views on the value of legal monopolies in medicine have been linked to his views on legal monopolies in software. Philanthropy Bill and Melinda Gates Foundation Gates studied the work of Andrew Carnegie and John D. Rockefeller, and donated some of his Microsoft stock in 1994 to create the "William H. Gates Foundation". In 2000, Gates and his wife combined three family foundations and Gates donated stock valued at $5 billion to create the charitable Bill & Melinda Gates Foundation, which was identified by the Funds for NGOs company in 2013, as the world's wealthiest charitable foundation, with assets reportedly valued at more than $34.6 billion. The foundation allows benefactors to access information that shows how its money is being spent, unlike other major charitable organizations such as the Wellcome Trust. Gates, through his foundation, also donated $20 million to Carnegie Mellon University for a new building to be named Gates Center for Computer Science which opened in 2009. Gates has credited the generosity and extensive philanthropy of David Rockefeller as a major influence. Gates and his father met with Rockefeller several times, and their charity work is partly modeled on the Rockefeller family's philanthropic focus, whereby they are interested in tackling the global problems that are ignored by governments and other organizations. , Bill and Melinda Gates were the second-most generous philanthropists in America, having given over $28 billion to charity; the couple plan to eventually donate 95% of their wealth to charity. The foundation is organized into five program areas: Global Development Division, Global Health Division, United States Division, and Global Policy & Advocacy Division. Among others, it supports a wide range of public health projects, granting aid to fight transmissible diseases such AIDS, tuberculosis and malaria, as well as widespread vaccine programs to eradicate polio. It grants funds to learning institutes and libraries and supports scholarships at universities. The foundation established a water, sanitation and hygiene program to provide sustainable sanitation services in poor countries. Its agriculture division supports the International Rice Research Institute in developing Golden Rice, a genetically modified rice variant used to combat vitamin A deficiency. The goal of the foundation is to provide 120 million women and girls, in the poorest countries, with high-quality contraceptive information and services, with the longer-term goal of universal access to voluntary family planning. In 2007, the Los Angeles Times criticized the foundation for investing its assets in companies that have been accused of worsening poverty, pollution and pharmaceutical firms that do not sell to developing countries. Although the foundation announced a review of its investments to assess social responsibility, it was subsequently canceled and upheld its policy of investing for maximum return, while using voting rights to influence company practices. Gates delivered his thoughts in a fireside chat moderated by journalist and news anchor Shereen Bhan virtually at the Singapore FinTech Festival on December 8, 2020, on the topic, "Building Infrastructure for Resilience: What the COVID-19 Response Can Teach Us About How to Scale Financial Inclusion". Gates favours the normalization of COVID-19 masks. In a November 2020 interview, he said: "What are these, like, nudists? I mean, you know, we ask you to wear pants, and no American says, or very few Americans say, that that's, like, some terrible thing." Personal donations Melinda Gates suggested that people should emulate the philanthropic efforts of the Salwen family, who sold their home and gave away half of its value, as detailed in their book, The Power of Half. Gates and his wife invited Joan Salwen to Seattle to speak about what the family had done, and on December 9, 2010, Bill and Melinda Gates and investor Warren Buffett each signed a commitment they called the "Giving Pledge", which is a commitment by all three to donate at least half of their wealth, over the course of time, to charity. Gates has also provided personal donations to educational institutions. In 1999, Gates donated $20 million to the Massachusetts Institute of Technology for the construction of a computer laboratory named the "William H. Gates Building" that was designed by architect Frank Gehry. While Microsoft had previously given financial support to the institution, this was the first personal donation received from Gates. The Maxwell Dworkin Laboratory of the Harvard John A. Paulson School of Engineering and Applied Sciences is named after the mothers of both Gates and Microsoft President Steven A. Ballmer, both of whom were students (Ballmer was a member of the school's graduating class of 1977, while Gates left his studies for Microsoft), and donated funds for the laboratory's construction. Gates also donated $6 million to the construction of the Gates Computer Science Building, completed in January 1996, on the campus of Stanford University. The building contains the Computer Science Department and the Computer Systems Laboratory (CSL) of Stanford's Engineering department. Since 2005, Gates and his foundation have taken an interest in solving global sanitation problems. For example, they announced the "Reinvent the Toilet Challenge", which has received considerable media interest. To raise awareness for the topic of sanitation and possible solutions, Gates drank water that was "produced from human feces" in 2014 – it was produced from a sewage sludge treatment process called the Omni Processor. In early 2015, he also appeared with Jimmy Fallon on The Tonight Show and challenged him to see if he could taste the difference between this reclaimed water or bottled water. In November 2017, Gates said he would give $50 million to the Dementia Discovery Fund, a venture capital fund that seeks treatment for Alzheimer's disease. He also pledged an additional $50 million to start-up ventures working in Alzheimer's research. Bill and Melinda Gates have said that they intend to leave their three children $10 million each as their inheritance. With only $30 million kept in the family, they are expected to give away about 99.96% of their wealth. On August 25, 2018, Gates distributed $600,000 through his foundation via UNICEF which is helping flood affected victims in Kerala, India. Charity sports events On April 29, 2017, Gates partnered with Swiss tennis legend Roger Federer in playing in the Match for Africa 4, a noncompetitive tennis match at a sold-out Key Arena in Seattle. The event was in support of the Roger Federer Foundation's charity efforts in Africa. Federer and Gates played against John Isner, the top-ranked American player for much of this decade, and Mike McCready, the lead guitarist for Pearl Jam. The pair won the match 6 games to 4. Overall, they raised $2 million for children in Africa. The following year, Gates and Federer returned to play in the Match for Africa 5 on March 5, 2018, at San Jose's SAP Center. Their opponents were Jack Sock, one of the top American players and a grand slam winner in doubles, and Savannah Guthrie, a co-anchor for NBC's Today show. Gates and Federer recorded their second match victory together by a score of 6–3 and the event raised over $2.5 million. Books Gates has written three books: The Road Ahead, written with Microsoft executive Nathan Myhrvold and journalist Peter Rinearson, was published in November 1995. It summarized the implications of the personal computing revolution and described a future profoundly changed by the arrival of a global information superhighway. Business @ the Speed of Thought was published in 1999, and discusses how business and technology are integrated, and shows how digital infrastructures and information networks can help to get an edge on the competition. How to Avoid a Climate Disaster (February 2021) presents what Gates learned in over a decade of studying climate change and investing in innovations to address climate problems. Personal life Gates is an avid reader, and the ceiling of his large home library is engraved with a quotation from The Great Gatsby. He also enjoys bridge, tennis and golf. His days are planned for him on a minute-by-minute basis, similarly to the U.S. president's schedule. Despite his wealth and extensive business travel, Gates flew coach (economy class) in commercial aircraft until 1997, when he bought a private jet. Gates purchased the Codex Leicester, a collection of scientific writings by Leonardo da Vinci, for US$30.8 million at an auction in 1994. In 1998, he reportedly paid $30 million for the original 1885 maritime painting Lost on the Grand Banks, at the time a record price for an American painting. In 2016, he revealed that he was color-blind. Marriage and divorce Gates married Melinda French on the Hawaiian Island of Lanai on January 1, 1994. They met in 1987 after Melinda began working at Microsoft. At the time of their marriage, Gates was given permission by Melinda to spend limited time with his ex-girlfriend, businesswoman Ann Winblad. Bill and Melinda have three children: Jennifer, Rory and Phoebe. The family's residence is an earth-sheltered mansion in the side of a hill overlooking Lake Washington in Medina, Washington. In 2009, property taxes on the mansion were reported to be US$1.063 million, on a total assessed value of US$147.5 million. The estate has a swimming pool with an underwater music system, as well as a gym and a dining room. On May 3, 2021, the Gateses announced they had decided to divorce after 27 years of marriage and 34 years as a couple. They said they would keep working together on charitable efforts. The Wall Street Journal reported that Melinda had been meeting with divorce attorneys since 2019, citing interviews that suggested Bill's ties with Jeffrey Epstein was at least one of her concerns. The divorce was finalized on August 2, 2021. Relationship with Jeffrey Epstein A New York Times article reported that Gates's relationship with convicted sex offender Jeffrey Epstein started in 2011, just a few years after Epstein's conviction, and continued for some years, including a visit to Epstein's house with Melinda in the fall of 2013, despite her declared discomfort. Gates said in 2011 about Epstein: "His lifestyle is very different and kind of intriguing although it would not work for me". The depth of the friendship between Gates and Epstein is unclear. Gates generally commented about his relationship with Epstein that "I met him. I didn't have any business relationship or friendship with him". However, Gates visited Epstein "many times, despite [Epstein's] past". Gates took at least one flight in 2013 in Epstein's infamous Lolita Express aircraft. It was reported that Epstein and Gates "discussed the Gates Foundation and philanthropy". However, in an interview in 2019 Gates completely denied any connection between Epstein and the Gates Foundation or his philanthropy generally. In August 2021, Gates said the reason he had meetings with Epstein was because Gates hoped Epstein could provide money for philanthropic work, though nothing came of the idea. Gates added, "It was a huge mistake to spend time with him, to give him the credibility of being there." It has also been reported that Epstein and Gates met with Nobel Committee chair Thorbjørn Jagland at his residence in Strasbourg, France in March 2013 to discuss the Nobel Prize. Also in attendance were representatives of the International Peace Institute which has received millions in grants from the Gates Foundation, including a $2.5 million "community engagement" grant in October 2013. Public image Gates's public image has changed over the years. At first he was perceived as a brilliant but ruthless "robber baron", a "nerd-turned-tycoon". Starting in 2000 with the foundation of the Bill and Melinda Gates Foundation, and particularly after he stepped down as head of Microsoft, he turned his attention to philanthropy, spending more than $50 billion on causes like health, poverty, and education. His image morphed "from tyrannical technocrat to saintly savior", a "huggable billionaire techno-philanthropist", celebrated on magazine covers and sought after for his opinions on major issues like global health and climate change. Still another shift in public opinion came in 2021 with the announcement that he and Melinda were divorcing. Coverage of that proceeding brought out information about romantic pursuits of women who worked for him, a long-term extra-marital affair, and a friendship with convicted child sex trafficker Jeffrey Epstein. This resulted in some deterioration of his public image. Religion In an interview with Rolling Stone, Gates said in regard to his faith: "The moral systems of religion, I think, are super important. We've raised our kids in a religious way; they've gone to the Catholic church that Melinda goes to and I participate in. I've been very lucky, and therefore I owe it to try and reduce the inequity in the world. And that's kind of a religious belief. I mean, it's at least a moral belief." In the same 2014 interview he also said: "I agree with people like Richard Dawkins that mankind felt the need for creation myths. Before we really began to understand disease and the weather and things like that, we sought false explanations for them. Now science has filled in some of the realm – not all – that religion used to fill. But the mystery and the beauty of the world is overwhelmingly amazing, and there's no scientific explanation of how it came about. To say that it was generated by random numbers, that does seem, you know, sort of an uncharitable view [laughs]. I think it makes sense to believe in God, but exactly what decision in your life you make differently because of it, I don't know." Wealth tallies In 1999, his wealth briefly surpassed US$101 billion. Since 2000, the nominal value of his Microsoft holdings has declined due to a fall in Microsoft's stock price after the dot-com bubble burst and the multi-billion dollar donations he has made to his charitable foundations. In May 2006, Gates remarked that he wished that he were not the richest man in the world because he disliked the attention it brought. In March 2010, Gates was the second wealthiest person after Carlos Slim, but regained the top position in 2013, according to the Bloomberg Billionaires List. Slim retook the position again in June 2014 (but then lost the top position back to Gates). Between 2009 and 2014, his wealth doubled from US$40 billion to more than US$82 billion. In October 2017, Gates was surpassed by Amazon founder Jeff Bezos as the richest person in the world. On November 15, 2019, he once again became the richest person in the world after a 48% increase in Microsoft shares, surpassing Bezos. Gates told the BBC, "I've paid more tax than any individual ever, and gladly so ... I've paid over $6 billion in taxes." He is a proponent of higher taxes, particularly for the rich. By 2017, Gates had held the top spot on the list of The World's Billionaires for 18 out of the previous 23 years. Gates has several investments outside Microsoft, which in 2006 paid him a salary of US$616,667 and US$350,000 bonus totalling US$966,667. In 1989, he founded Corbis, a digital imaging company. In 2004, he became a director of Berkshire Hathaway, the investment company headed by long-time friend Warren Buffett. In 1987, Gates was listed as a billionaire in Forbes magazine's 400 Richest People in America issue, worth $1.25 billion at the time, and was the world's youngest self-made billionaire. Since 1987, Gates has been included in the Forbes The World's Billionaires list and was the wealthiest person from 1995 to 1996, 1998 to 2007, 2009, and held the spot until 2018 before being overtaken by Jeff Bezos. Gates was number one on the Forbes 400 list from 1993 through to 2007, 2009, and 2014 through 2017. Recognition Time magazine named Gates one of the 100 people who most influenced the 20th century, as well as one of the 100 most influential people of 2004, 2005, and 2006. Time also collectively named Gates, his wife Melinda and U2's lead singer Bono as the 2005 Persons of the Year for their humanitarian efforts. In 2006, he was voted eighth in the list of "Heroes of our time". Gates was listed in the London Sunday Times power list in 1999, named CEO of the year by Chief Executive Officers magazine in 1994, ranked number one in the "Top 50 Cyber Elite" by Time in 1998, ranked number two in the Upside Elite 100 in 1999, and was included in The Guardian as one of the "Top 100 influential people in media" in 2001. Gates was elected Member of the US National Academy of Engineering in 1996 "for contributions to the founding and development of personal computing". He was named Honorary Member of the American Library Association in 1998. He was elected a foreign member of the Chinese Academy of Engineering in 2017. According to Forbes, Gates was ranked as the fourth most powerful person in the world in 2012, up from fifth in 2011. In 1994, he was honored as the 20th Distinguished Fellow of the British Computer Society (DFBCS). In 1999, Gates received New York Institute of Technology's President's Medal. Gates has received honorary doctorates from Nyenrode Business Universiteit (1996), KTH Royal Institute of Technology (2002), Waseda University (2005), Tsinghua University (2007), Harvard University (2007), the Karolinska Institute (2007), and Cambridge University (2009). He was also made an honorary trustee of Peking University in 2007. Gates was made an Honorary Knight Commander of the Order of the British Empire (KBE) by Queen Elizabeth II in 2005. In January 2006, he was awarded the Grand Cross of the Order of Prince Henry by the President of Portugal Jorge Sampaio In November 2006, he was awarded the Placard of the Order of the Aztec Eagle, together with his wife Melinda who was awarded the Insignia of the same order, both for their philanthropic work around the world in the areas of health and education, particularly in Mexico, and specifically in the program "". Gates received the 2010 Bower Award for Business Leadership from The Franklin Institute for his achievements at Microsoft and his philanthropic work. Also in 2010, he was honored with the Silver Buffalo Award by the Boy Scouts of America, its highest award for adults, for his service to youth. In 2002, Bill and Melinda Gates received the Jefferson Award for Greatest Public Service Benefiting the Disadvantaged. He was given the 2006 James C. Morgan Global Humanitarian Award from the Tech Awards. In 2015, Gates and his wife Melinda received the Padma Bhushan, India's third-highest civilian award for their social work in the country. In 2016, Barack Obama honored Bill and Melinda Gates with the Presidential Medal of Freedom for their philanthropic efforts. In 2017, François Hollande awarded Bill and Melinda Gates with France's highest national order, the Commander of the Legion of Honour, for their charity efforts. Entomologists named Bill Gates' flower fly, , in his honor in 1997. In 2021 Bill Gates was nominated at the 11th annual Streamy Awards for the crossover for his personal YouTube channel. In 2022 Bill Gates received the Hilal-e-Pakistan Second-highest civilian award for their social work in the country.

In baseball, hit by pitch (HBP) is an event in which a batter or his clothing or equipment (other than his bat) is struck directly by a pitch from the pitcher; the batter is called a hit batsman (HB). A hit batsman is awarded first base, provided that (in the plate umpire's judgment) he made an honest effort to avoid the pitch, although failure to do so is rarely called by an umpire. Being hit by a pitch is often caused by a batter standing too close to, or "crowding", home plate. The rule dates from 1884; before that, a pitch that struck the batter was merely a ball. Official rule Per baseball official rule 5.05(b), a batter becomes a baserunner and is awarded first base when he or his equipment (except for his bat): is touched by a pitched ball outside the strike zone, and he attempts to avoid it (or had no opportunity to avoid it), and he did not swing at the pitch. If all these conditions are met, the ball is dead, and other baserunners advance if they are forced to vacate their base by the batter taking first. Rule 5.09(a) further clarifies that a hit by pitch is also called when a pitch touches a batter's clothing. In the case where a batter swings and the pitch hits him anyway, the ball is dead and a strike is called. If the batter does not attempt to avoid the pitch, he is not awarded first base, and the pitch is ruled either a strike if in the strike zone or a ball if out of the strike zone. Umpires rarely make this call. A famous instance of a non-hit by pitch was on May 31, 1968, when Don Drysdale hit Dick Dietz with a pitch that would have forced in a run and ended Drysdale's scoreless innings streak at 44. Umpire Harry Wendelstedt ruled that Dietz made no effort to avoid the pitch; Dietz proceeded to fly out, and Drysdale's scoreless streak continued to a then-record 58 innings. A hit-by-pitch can also be called on a pitch that has first touched the ground before hitting the batter. Such a bouncing pitch is like any other, and if a batter is hit by such a pitch, he will be awarded first unless he made no attempt to avoid it (and he had an opportunity to avoid it). A batter hit by a pitch is not credited with a hit or at bat, but is credited with a time on base and a plate appearance; therefore, being hit by a pitch does not increase or decrease a player's batting average but does increase his on-base percentage. A batter hit by a pitch with the bases loaded is also credited with an RBI per MLB rule 10.04(a)(2). A pitch ruled a hit by pitch is recorded as a ball in the pitcher's pitch count, since by definition the ball must be outside the strike zone and not have been swung at. The rule awarding first base to a batter hit by a pitch was instituted in 1887. Tactical use Inside pitching is a common and legal tactic in baseball, and many players make use of brushback pitches, or pitches aimed underneath the chin, commonly referred to as "chin music", to keep players away from the plate. "Headhunter" is a common term for pitchers who have a reputation for throwing these kinds of pitches. However, throwing at a batter intentionally is illegal, and can be very dangerous. When an umpire suspects that a pitcher has thrown at a batter intentionally, but is not certain, a warning is issued to the pitcher and the managers of both teams. From that point on, any pitch thrown at a batter can cause the pitcher and the manager of the offending team to be ejected immediately from the game. Serious offenses such as a ball thrown at the head (called a beanball) can result in the immediate ejection of the pitcher, and the manager if he ordered the beanball, even without a warning. If the umpire is certain that the pitcher intentionally hit the batter with the pitch, the pitcher is ejected from the game with no warning. This infamously happened on 15 August 2018, when José Ureña was ejected from a game against the Atlanta Braves after hitting Ronald Acuña Jr. on the elbow with the first pitch of the game, which led to the Braves' and Marlins' benches clearing. Occasionally, if a player is acting rude or unsportsmanlike, or having an extraordinarily good day, the pitcher may intentionally hit the batter, disguising it as a pitch that accidentally slipped his control. Managers may also order a pitcher to throw such a pitch (sometimes called a "plunking"). These pitches are typically aimed at the lower back and slower than normal, designed to send a message more than anything else. The opposing team usually hits a batter in retaliation for this act. The plunkings generally end there because of umpire warnings, but in some cases things can get out of hand, and sometimes they lead to the batter charging the mound, bench-clearing brawls, and several ejections. Records The all-time record for a player being hit by a pitch is held by Hughie Jennings, who was hit by 287 pitches between 1891 and 1903. The modern-era record is held by Craig Biggio of the Houston Astros, who had 285 as of the end of the 2007 season when he retired. Prior to Biggio, the modern-era record belonged to Don Baylor, who was hit 267 times. The all-time single-season record also belongs to Jennings, who was hit 51 times during the 1896 season. Ron Hunt of the 1971 Montreal Expos was hit 50 times during that year, the modern-era record. The single-game record is three, held by numerous players. The all-time record for pitchers is held by Gus Weyhing with 277 (1887–1901). The modern-era career pitching record for most hit batsmen is 205 by Hall-of-Famer Walter Johnson. The season record is 54 by Phil Knell in 1891, and the game record is six, held by Ed Knouff and John Grimes. Brady Anderson was the first player to be hit by a pitch two times in the same inning in an American League game. On April 25, 2014, Brandon Moss became the second when he was hit twice in the top of the 9th inning by Houston Astros pitchers. Five players have been hit by a pitch twice in the same inning in the National League. On September 1, 2021, Austin Adams became the first pitcher hitting batters 20 or more times with 120 or less IPs in a season. Ed Doheny hit batters 22 times in 133.2 IP in 1900. Twice has a perfect game been broken up by the 27th batter being hit by pitch. Hooks Wiltse and Max Scherzer hold this rare feat. Both finished with no-hitters after the hit by pitch. Scherzer's team was leading 6-0 when he pitched his no-hitter, but Wiltse's team was scoreless through 9; he pitched a 10-inning 1–0 no-hitter. The record for most hit batters in a no-hitter is three, held by Chris Heston of the San Francisco Giants for his 2015 effort against the New York Mets. Postseason career records are held by Greg Maddux and Tim Wakefield—each of whom hit 9 batters—and Shane Victorino, who was hit by pitch 11 times. Dangers One major league player died as a result of being struck by a pitch: Ray Chapman of the Cleveland Indians was hit in the head by Carl Mays on August 16, 1920, and died the next morning. Serious injuries may result from being hit by a pitch, even when wearing a batting helmet. On August 18, 1967, Red Sox batter Tony Conigliaro was hit almost directly in the left eye by a fastball thrown by Jack Hamilton of the California Angels. His cheekbone was shattered; he nearly lost the sight of the eye, was unable to play for over a year, and never regained his earlier batting ability. Batting helmets at the time were not required to have an "ear flap"; it was not until 2002 that all Major League batters were required to wear helmets with side-protection. Ron Santo was the first player to wear a helmet with an improvised ear-flap, in 1966. He had it made after he was struck by a pitch from Jack Fisher that briefly knocked him unconscious and put him on the Disabled List for two weeks with a fractured cheekbone. On September 28, 1995, Kirby Puckett, of the Minnesota Twins, was struck in the cheek by a Dennis Martínez fastball, breaking his jaw and loosening two teeth. It would be his last regular-season game; during spring training the following year he developed glaucoma, which ended his career. Most recently, Mike Piazza, then of the New York Mets, was hit in the head by a pitch from Julián Tavárez of the St. Louis Cardinals on September 10, 2005. His helmet shattered, and he suffered a concussion. Other relatively minor injuries that are possible include broken fingers or hands, broken feet, broken ribs, injuries to the knee, or groin injuries. Legal interpretation Since inside pitching is a legitimate tactic in baseball, courts have recognized that being hit by a pitch is an inherent risk of the game, so that players cannot sue for any resulting injuries. On April 6, 2006, in a case arising from a game involving community college baseball teams, the Supreme Court of California ruled that baseball players in California assume the risk of being hit by baseballs even if the balls were intentionally thrown so as to cause injury. In the court's words: "For better or worse, being intentionally thrown at is a fundamental part and inherent risk of the sport of baseball. It is not the function of tort law to police such conduct."

In Major League Baseball, the American League Division Series (ALDS) determines which two teams from the American League will advance to the American League Championship Series. The Division Series consists of two best-of-five series, featuring the three division winners and the winner of the wild-card play-off. History The Division Series was implemented in 1981 as a one-off tournament because of a midseason strike, with the first place teams before the strike taking on the teams in first place after the strike. In 1981, a split-season format forced the first ever divisional playoff series, in which the New York Yankees won the Eastern Division series over the Milwaukee Brewers (who were in the American League until 1998) in five games while in the Western Division, the Oakland Athletics swept the Kansas City Royals (the only team with an overall losing record to ever make the postseason). In 1994, it was returned permanently when Major League Baseball (MLB) restructured each league into three divisions, but with a different format than in 1981. Each of the division winners, along with one wild card team, qualify for the Division Series. Despite being planned for the 1994 season, the post-season was cancelled that year due to the 1994–95 Major League Baseball strike. In 1995, the first season to feature a division series, the Western Division champion Seattle Mariners defeated the wild card New York Yankees three games to two, while the Central Division champion Cleveland Indians defeated the Eastern Division champion Boston Red Sox in a three game sweep. From 1994–2011, the wild card was given to the team in the American League with the best overall record that was not a division champion. Beginning with the 2012 season, a second wild card team was added, and the two wild card teams play a single-game playoff to determine which team would play in the ALDS. For the 2020 Major League Baseball season only, there was an expanded playoff format, owing to an abbreviated 60-game regular season due to the COVID-19 pandemic. Eight teams qualified from the American League: the top two teams in each division plus the next two best records among the remaining teams. These eight teams played a best-of-three game series to determine placement in the ALDS. The regular format returned for the 2021 season. As of 2021, the Yankees have played in and won the most division series, with thirteen wins in twenty-two appearances. In 2015, the Toronto Blue Jays and Houston Astros were the final American League teams to make their first appearances in the ALDS. The Astros had been in the National League through 2012, and had played in the National League Division Series (NLDS) seven times. Determining the matchups The ALDS is a best-of-five series where the wild card team is assigned to play the divisional winner with the best winning percentage in the regular season in one series, and the other two division winners met in the other series with the team with the second best winning percentage, getting home-field. (From 1998 to 2011, if the wild-card team and the division winner with the best record were from the same division, the wild-card team played the division winner with the second-best record, and the remaining two division leaders played each other.) The two series winners move on to the best-of-seven ALCS. According to Nate Silver, the advent of this playoff series, and especially of the wild card, has caused teams to focus more on "getting to the playoffs" rather than "winning the pennant" as the primary goal of the regular season. Beginning with the 2012 season, the wild card team that advances to the Division Series was to face the number 1 seed, regardless whether or not they are in the same division. The two series winners move on to the best-of-seven ALCS. Home-field advantage goes to the team with the better regular season record (or head-to-head record if there is a tie between two or more teams), except for the wild card team, which never receives the home field advantage. Beginning in 2003, MLB has implemented a new rule to give the team from the league that wins the All-Star Game with the best regular season record a slightly greater advantage. In order to spread out the Division Series games for broadcast purposes, the two ALDS series follow one of two off-day schedules. Starting in 2007, after consulting the MLBPA, MLB has decided to allow the team with the best record in the league that wins the All-Star Game to choose whether to use the seven-day schedule (1-2-off-3-4-off-5) or the eight-day schedule (1-off-2-off-3-4-off-5). The team only gets to choose the schedule; the opponent is still determined by win-loss records. Initially, the best-of-5 series played in a 2–3 format, with the first two games set at home for the lower seed team and the last three for the higher seed. Since 1998, the series has followed a 2–2–1 format, where the higher seed team plays at home in Games 1 and 2, the lower seed plays at home in Game 3 and Game 4 (if necessary), and if a Game 5 is needed, the teams return to the higher seed's field. When MLB added a second wild card team in 2012, the Division Series re-adopted the 2–3 format due to scheduling conflicts. It reverted to the 2–2–1 format starting in 2013.

The Baroque (, ; ) is a style of architecture, music, dance, painting, sculpture, and other arts that flourished in Europe from the early 17th century until the 1740s. In the territories of the Spanish and Portuguese empires including the Iberian Peninsula it continued, together with new styles, until the first decade of the 19th century. It followed Renaissance art and Mannerism and preceded the Rococo (in the past often referred to as "late Baroque") and Neoclassical styles. It was encouraged by the Catholic Church as a means to counter the simplicity and austerity of Protestant architecture, art, and music, though Lutheran Baroque art developed in parts of Europe as well. The Baroque style used contrast, movement, exuberant detail, deep colour, grandeur, and surprise to achieve a sense of awe. The style began at the start of the 17th century in Rome, then spread rapidly to France, northern Italy, Spain, and Portugal, then to Austria, southern Germany, and Russia. By the 1730s, it had evolved into an even more flamboyant style, called rocaille or Rococo, which appeared in France and Central Europe until the mid to late 18th century. In the decorative arts, the style employs plentiful and intricate ornamentation. The departure from Renaissance classicism has its own ways in each country. But a general feature is that everywhere the starting point is the ornamental elements introduced by the Renaissance. The classical repertoire is crowded, dense, overlapping, loaded, in order to provoke shock effects. New motifs introduced by Baroque are: the cartouche, trophies and weapons, baskets of fruit or flowers, and others, made in marquetry, stucco, or carved. Origin of the word The English word baroque comes directly from the French (as the modern standard English-language spelling might suggest). Some scholars state that the French word originated from the Portuguese term barroco ("a flawed pearl"), pointing to the Latin verruca, ("wart"), or to a word with the suffix -ǒccu (common in pre-Roman Iberia). Other sources suggest a Medieval Latin term used in logic, , as the most likely source. In the 16th century, the Medieval Latin word baroco moved beyond scholastic logic and came into use to characterise anything that seemed absurdly complex. The French philosopher Michel de Montaigne (1533–1592) associated the term baroco with "Bizarre and uselessly complicated." Other early sources associate baroco with magic, complexity, confusion, and excess. The word baroque was also associated with irregular pearls before the 18th century. The French baroque and Portuguese barroco were terms often associated with jewelry. An example from 1531 uses the term to describe pearls in an inventory of Charles V of France's treasures. Later, the word appears in a 1694 edition of Le Dictionnaire de l'Académie Française, which describes baroque as "only used for pearls that are imperfectly round." A 1728 Portuguese dictionary similarly describes barroco as relating to a "coarse and uneven pearl". An alternative derivation of the word baroque points to the name of the Italian painter Federico Barocci (1528–1612). In the 18th century the term began to be used to describe music, and not in a flattering way. In an anonymous satirical review of the première of Jean-Philippe Rameau's Hippolyte et Aricie in October 1733, which was printed in the Mercure de France in May 1734, the critic wrote that the novelty in this opera was "du barocque", complaining that the music lacked coherent melody, was unsparing with dissonances, constantly changed key and meter, and speedily ran through every compositional device. In 1762 Le Dictionnaire de l'Académie Française recorded that the term could figuratively describe something "irregular, bizarre or unequal". Jean-Jacques Rousseau, who was a musician and composer as well as a philosopher, wrote in 1768 in the Encyclopédie: "Baroque music is that in which the harmony is confused, and loaded with modulations and dissonances. The singing is harsh and unnatural, the intonation difficult, and the movement limited. It appears that term comes from the word 'baroco' used by logicians." In 1788 Quatremère de Quincy defined the term in the Encyclopédie Méthodique as "an architectural style that is highly adorned and tormented". The French terms style baroque and musique baroque appeared in Le Dictionnaire de l'Académie Française in 1835. By the mid-19th century, art critics and historians had adopted the term "baroque" as a way to ridicule post-Renaissance art. This was the sense of the word as used in 1855 by the leading art historian Jacob Burckhardt, who wrote that baroque artists "despised and abused detail" because they lacked "respect for tradition". In 1888 the art historian Heinrich Wölfflin published the first serious academic work on the style, Renaissance und Barock, which described the differences between the painting, sculpture, and architecture of the Renaissance and the Baroque. Architecture: origins and characteristics The Baroque style of architecture was a result of doctrines adopted by the Catholic Church at the Council of Trent in 1545–63, in response to the Protestant Reformation. The first phase of the Counter-Reformation had imposed a severe, academic style on religious architecture, which had appealed to intellectuals but not the mass of churchgoers. The Council of Trent decided instead to appeal to a more popular audience, and declared that the arts should communicate religious themes with direct and emotional involvement. Similarly, Lutheran Baroque art developed as a confessional marker of identity, in response to the Great Iconoclasm of Calvinists. Baroque churches were designed with a large central space, where the worshippers could be close to the altar, with a dome or cupola high overhead, allowing light to illuminate the church below. The dome was one of the central symbolic features of Baroque architecture illustrating the union between the heavens and the earth, The inside of the cupola was lavishly decorated with paintings of angels and saints, and with stucco statuettes of angels, giving the impression to those below of looking up at heaven. Another feature of Baroque churches are the quadratura; trompe-l'œil paintings on the ceiling in stucco frames, either real or painted, crowded with paintings of saints and angels and connected by architectural details with the balustrades and consoles. Quadratura paintings of Atlantes below the cornices appear to be supporting the ceiling of the church. Unlike the painted ceilings of Michelangelo in the Sistine Chapel, which combined different scenes, each with its own perspective, to be looked at one at a time, the Baroque ceiling paintings were carefully created so the viewer on the floor of the church would see the entire ceiling in correct perspective, as if the figures were real. The interiors of Baroque churches became more and more ornate in the High Baroque, and focused around the altar, usually placed under the dome. The most celebrated baroque decorative works of the High Baroque are the Chair of Saint Peter (1647–53) and the Baldachino of St. Peter (1623–34), both by Gian Lorenzo Bernini, in St. Peter's Basilica in Rome. The Baldequin of St. Peter is an example of the balance of opposites in Baroque art; the gigantic proportions of the piece, with the apparent lightness of the canopy; and the contrast between the solid twisted columns, bronze, gold and marble of the piece with the flowing draperies of the angels on the canopy. The Dresden Frauenkirche serves as a prominent example of Lutheran Baroque art, which was completed in 1743 after being commissioned by the Lutheran city council of Dresden and was "compared by eighteenth-century observers to St Peter's in Rome". The twisted column in the interior of churches is one of the signature features of the Baroque. It gives both a sense of motion and also a dramatic new way of reflecting light. The cartouche was another characteristic feature of Baroque decoration. These were large plaques carved of marble or stone, usually oval and with a rounded surface, which carried images or text in gilded letters, and were placed as interior decoration or above the doorways of buildings, delivering messages to those below. They showed a wide variety of invention, and were found in all types of buildings, from cathedrals and palaces to small chapels. Baroque architects sometimes used forced perspective to create illusions. For the Palazzo Spada in Rome, Borromini used columns of diminishing size, a narrowing floor and a miniature statue in the garden beyond to create the illusion that a passageway was thirty meters long, when it was actually only seven meters long. A statue at the end of the passage appears to be life-size, though it is only sixty centimeters high. Borromini designed the illusion with the assistance of a mathematician. Italian Baroque The first building in Rome to have a Baroque facade was the Church of the Gesù in 1584; it was plain by later Baroque standards, but marked a break with the traditional Renaissance facades that preceded it. The interior of this church remained very austere until the high Baroque, when it was lavishly ornamented. In Rome in 1605, Paul V became the first of series of popes who commissioned basilicas and church buildings designed to inspire emotion and awe through a proliferation of forms, and a richness of colours and dramatic effects. Among the most influential monuments of the Early Baroque were the facade of St. Peter's Basilica (1606–1619), and the new nave and loggia which connected the facade to Michelangelo's dome in the earlier church. The new design created a dramatic contrast between the soaring dome and the disproportionately wide facade, and the contrast on the facade itself between the Doric columns and the great mass of the portico. In the mid to late 17th century the style reached its peak, later termed the High Baroque. Many monumental works were commissioned by Popes Urban VIII and Alexander VII. The sculptor and architect Gian Lorenzo Bernini designed a new quadruple colonnade around St. Peter's Square (1656 to 1667). The three galleries of columns in a giant ellipse balance the oversize dome and give the Church and square a unity and the feeling of a giant theatre. Another major innovator of the Italian High Baroque was Francesco Borromini, whose major work was the Church of San Carlo alle Quattro Fontane or Saint Charles of the Four Fountains (1634–46). The sense of movement is given not by the decoration, but by the walls themselves, which undulate and by concave and convex elements, including an oval tower and balcony inserted into a concave traverse. The interior was equally revolutionary; the main space of the church was oval, beneath an oval dome. Painted ceilings, crowded with angels and saints and trompe-l'œil architectural effects, were an important feature of the Italian High Baroque. Major works included The Entry of Saint Ignatius into Paradise by Andrea Pozzo (1685–1695) in the Church of Saint Ignatius in Rome, and The triumph of the name of Jesus by Giovanni Battista Gaulli in the Church of the Gesù in Rome (1669–1683), which featured figures spilling out of the picture frame and dramatic oblique lighting and light-dark contrasts. The style spread quickly from Rome to other regions of Italy: It appeared in Venice in the church of Santa Maria della Salute (1631–1687) by Baldassare Longhena, a highly original octagonal form crowned with an enormous cupola. It appeared also in Turin, notably in the Chapel of the Holy Shroud (1668–1694) by Guarino Guarini. The style also began to be used in palaces; Guarini designed the Palazzo Carignano in Turin, while Longhena designed the Ca' Rezzonico on the Grand Canal, (1657), finished by Giorgio Massari with decorated with paintings by Giovanni Battista Tiepolo. A series of massive earthquakes in Sicily required the rebuilding of most of them and several were built in the exuberant late Baroque or Rococo style. Spanish Baroque The Catholic Church in Spain, and particularly the Jesuits, were the driving force of Spanish Baroque architecture. The first major work in this style was the San Isidro Chapel in Madrid, begun in 1643 by Pedro de la Torre. It contrasted an extreme richness of ornament on the exterior with simplicity in the interior, divided into multiple spaces and using effects of light to create a sense of mystery. The Cathedral in Santiago de Compostela was modernized with a series of Baroque additions beginning at the end of the 17th century, starting with a highly ornate bell tower (1680), then flanked by two even taller and more ornate towers, called the Obradorio, added between 1738 and 1750 by Fernando de Casas Novoa. Another landmark of the Spanish Baroque is the chapel tower of the Palace of San Telmo in Seville by Leonardo de Figueroa. Granada had only been conquered from the Moors in the 15th century, and had its own distinct variety of Baroque. The painter, sculptor and architect Alonso Cano designed the Baroque interior of Granada Cathedral between 1652 and his death in 1657. It features dramatic contrasts of the massive white columns and gold decor. The most ornamental and lavishly decorated architecture of the Spanish Baroque is called Churrigueresque style, named after the brothers Churriguera, who worked primarily in Salamanca and Madrid. Their works include the buildings on the city's main square, the Plaza Mayor of Salamanca (1729). This highly ornamental Baroque style was very influential in many churches and cathedrals built by the Spanish in the Americas. Other notable Spanish baroque architects of the late Baroque include Pedro de Ribera, a pupil of Churriguera, who designed the Royal Hospice of San Fernando in Madrid, and Narciso Tomé, who designed the celebrated El Transparente altarpiece at Toledo Cathedral (1729–32) which gives the illusion, in certain light, of floating upwards. The architects of the Spanish Baroque had an effect far beyond Spain; their work was highly influential in the churches built in the Spanish colonies in Latin America and the Philippines. The Church built by the Jesuits for a college in Tepotzotlán, with its ornate Baroque facade and tower, is a good example. Central Europe and Rococo (1740s–1770s) From 1680 to 1750, many highly ornate cathedrals, abbeys, and pilgrimage churches were built in Central Europe, in Bavaria, Austria, Bohemia and southwestern Poland. Some were in Rococo style, a distinct, more flamboyant and asymmetric style which emerged from the Baroque, then replaced it in Central Europe in the first half of the 18th century, until it was replaced in turn by classicism. The princes of the multitude of states in that region also chose Baroque or Rococo for their palaces and residences, and often used Italian-trained architects to construct them. Notable architects included Johann Fischer von Erlach, Lukas von Hildebrandt and Dominikus Zimmermann in Bavaria, Balthasar Neumann in Bruhl, and Matthäus Daniel Pöppelmann in Dresden. In Prussia, Frederick II of Prussia was inspired by the Grand Trianon of the Palace of Versailles, and used it as the model for his summer residence, Sanssouci, in Potsdam, designed for him by Georg Wenzeslaus von Knobelsdorff (1745–1747). Another work of Baroque palace architecture is the Zwinger in Dresden, the former orangerie of the palace of the Dukes of Saxony in the 18th century. One of the best examples of a rococo church is the Basilika Vierzehnheiligen, or Basilica of the Fourteen Holy Helpers, a pilgrimage church located near the town of Bad Staffelstein near Bamberg, in Bavaria, southern Germany. The Basilica was designed by Balthasar Neumann and was constructed between 1743 and 1772, its plan a series of interlocking circles around a central oval with the altar placed in the exact centre of the church. The interior of this church illustrates the summit of Rococo decoration. Another notable example of the style is the Pilgrimage Church of Wies (). It was designed by the brothers J. B. and Dominikus Zimmermann. It is located in the foothills of the Alps, in the municipality of Steingaden in the Weilheim-Schongau district, Bavaria, Germany. Construction took place between 1745 and 1754, and the interior was decorated with frescoes and with stuccowork in the tradition of the Wessobrunner School. It is now a UNESCO World Heritage Site. Another notable example is the St. Nicholas Church (Malá Strana) in Prague (1704–55), built by Christoph Dientzenhofer and his son Kilian Ignaz Dientzenhofer. Decoration covers all of walls of interior of the church. The altar is placed in the nave beneath the central dome, and surrounded by chapels, light comes down from the dome above and from the surrounding chapels. The altar is entirely surrounded by arches, columns, curved balustrades and pilasters of coloured stone, which are richly decorated with statuary, creating a deliberate confusion between the real architecture and the decoration. The architecture is transformed into a theatre of light, colour and movement. In Poland, the Italian-inspired Polish Baroque lasted from the early 17th to the mid-18th century and emphasised richness of detail and colour. The first Baroque building in present-day Poland and probably one of the most recognizable is the Church of St. Peter and Paul in Kraków, designed by Giovanni Battista Trevano. Sigismund's Column in Warsaw, erected in 1644, was the world's first secular Baroque monument built in the form of a column. The palatial residence style was exemplified by the Wilanów Palace, constructed between 1677 and 1696. The most renowned Baroque architect active in Poland was Dutchman Tylman van Gameren and his notable works include Warsaw's St. Kazimierz Church and Krasiński Palace, St. Anne's in Kraków and Branicki Palace in Bialystok. However, the most celebrated work of Polish Baroque is the Fara Church in Poznań, with details by Pompeo Ferrari. French Baroque or Classicism France largely resisted the ornate Baroque style of Italy, Spain, Vienna and the rest of Europe. The French Baroque style (often termed Grand Classicism or simply Classicism in France) is closely associated with the works built for Louis XIV and Louis XV; it features more geometric order and measure than Baroque, and less elaborate decoration on the facades and in the interiors. Louis XIV invited the master of Baroque, Bernini, to submit a design for the new wing of the Louvre, but rejected it in favor of a more classical design by Claude Perrault and Louis Le Vau. The principal architects of the style included François Mansart (Chateau de Balleroy, 1626–1636), Pierre Le Muet (Church of Val-de-Grace, 1645–1665), Louis Le Vau (Vaux-le-Vicomte, 1657–1661) and especially Jules Hardouin Mansart and Robert de Cotte, whose work included the Galerie des Glaces and the Grand Trianon at Versailles (1687–1688). Mansart was also responsible for the Baroque classicism of the Place Vendôme (1686–1699). The major royal project of the period was the expansion of Palace of Versailles, begun in 1661 by Le Vau with decoration by the painter Charles Le Brun. The gardens were designed by André Le Nôtre specifically to complement and amplify the architecture. The Galerie des Glaces (Hall of Mirrors), the centerpiece of the château, with paintings by Le Brun, was constructed between 1678 and 1686. Mansart completed the Grand Trianon in 1687. The chapel, designed by de Cotte, was finished in 1710. Following the death of Louis XIV, Louis XV added the more intimate Petit Trianon and the highly ornate theatre. The fountains in the gardens were designed to be seen from the interior, and to add to the dramatic effect. The palace was admired and copied by other monarchs of Europe, particularly Peter the Great of Russia, who visited Versailles early in the reign of Louis XV, and built his own version at Peterhof Palace near Saint Petersburg, between 1705 and 1725. Portuguese Baroque Baroque architecture in Portugal lasted about two centuries (the late seventeenth century and eighteenth century). The reigns of John V and Joseph I had increased imports of gold and diamonds, in a period called Royal Absolutism, which allowed the Portuguese Baroque to flourish. Baroque architecture in Portugal enjoys a special situation and different timeline from the rest of Europe. It is conditioned by several political, artistic, and economic factors, that originate several phases, and different kinds of outside influences, resulting in a unique blend, often misunderstood by those looking for Italian art, find instead specific forms and character which give it a uniquely Portuguese variety. Another key factor is the existence of the Jesuitical architecture, also called "plain style" (Estilo Chão or Estilo Plano) which like the name evokes, is plainer and appears somewhat austere. The buildings are single-room basilicas, deep main chapel, lateral chapels (with small doors for communication), without interior and exterior decoration, very simple portal and windows. It is a very practical building, allowing it to be built throughout the empire with minor adjustments, and prepared to be decorated later or when economic resources are available. In fact, the first Portuguese Baroque does not lack in building because "plain style" is easy to be transformed, by means of decoration (painting, tiling, etc.), turning empty areas into pompous, elaborate baroque scenarios. The same could be applied to the exterior. Subsequently, it is easy to adapt the building to the taste of the time and place and add on new features and details. Practical and economical. With more inhabitants and better economic resources, the north, particularly the areas of Porto and Braga, witnessed an architectural renewal, visible in the large list of churches, convents and palaces built by the aristocracy. Porto is the city of Baroque in Portugal. Its historical centre is part of UNESCO World Heritage List. Many of the Baroque works in the historical area of the city and beyond, belong to Nicolau Nasoni an Italian architect living in Portugal, drawing original buildings with scenographic emplacement such as the church and tower of Clérigos, the logia of the Porto Cathedral, the church of Misericórdia, the Palace of São João Novo, the Palace of Freixo, the Episcopal Palace (Portuguese: Paço Episcopal do Porto) along with many others. Russian Baroque The debut of Russian Baroque, or Petrine Baroque, followed a long visit of Peter the Great to western Europe in 1697–98, where he visited the Chateaux of Fontainebleau and the Versailles as well as other architectural monuments. He decided, on his return to Russia, to construct similar monuments in St. Petersburg, which became the new capital of Russia in 1712. Early major monuments in the Petrine Baroque include the Peter and Paul Cathedral and Menshikov Palace. During the reign of Empress Anna and Elizaveta Petrovna, Russian architecture was dominated by the luxurious Baroque style of Italian-born Bartolomeo Rastrelli, which developed into Elizabethan Baroque. Rastrelli's signature buildings include the Winter Palace, the Catherine Palace and the Smolny Cathedral. Other distinctive monuments of the Elizabethan Baroque are the bell tower of the Troitse-Sergiyeva Lavra and the Red Gate. In Moscow, Naryshkin Baroque became widespread, especially in the architecture of Eastern Orthodox churches in the late 17th century. It was a combination of western European Baroque with traditional Russian folk styles. Baroque in the Spanish and Portuguese Colonial Americas Due to the colonization of the Americas by European countries, the Baroque naturally moved to the New World, finding especially favorable ground in the regions dominated by Spain and Portugal, both countries being centralized and irreducibly Catholic monarchies, by extension subject to Rome and adherents of the Baroque Counter-reformist most typical. European artists migrated to America and made school, and along with the widespread penetration of Catholic missionaries, many of whom were skilled artists, created a multiform Baroque often influenced by popular taste. The Criollo and Indidenous craftsmen did much to give this Baroque unique features. The main centres of American Baroque cultivation, that are still standing, are (in this order) Mexico, Peru, Brazil, Ecuador, Cuba, Colombia, Bolivia, Guatemala, Panama and Puerto Rico. Of particular note is the so-called "Missionary Baroque", developed in the framework of the Spanish reductions in areas extending from Mexico and southwestern portions of current-day United States to as far south as Argentina and Chile, indigenous settlements organized by Spanish Catholic missionaries in order to convert them to the Christian faith and acculturate them in the Western life, forming a hybrid Baroque influenced by Native culture, where flourished Criollos and many Indian artisans and musicians, even literate, some of great ability and talent of their own. Missionaries' accounts often repeat that Western art, especially music, had a hypnotic impact on foresters, and the images of saints were viewed as having great powers. Many Indians were converted, and a new form of devotion was created, of passionate intensity, laden with mysticism, superstition, and theatricality, which delighted in festive masses, sacred concerts, and mysteries. The Colonial Baroque architecture in the Spanish America is characterized by a profuse decoration (portal of La Profesa Church, Mexico City; facades covered with Puebla-style azulejos, as in the Church of San Francisco Acatepec in San Andrés Cholula and Convent Church of San Francisco of Puebla), which will be exacerbated in the so-called Churrigueresque style (Facade of the Tabernacle of the Mexico City Cathedral, by Lorenzo Rodríguez; Church of San Francisco Javier, Tepotzotlán; Church of Santa Prisca of Taxco). In Peru, the constructions mostly developed in the cities of Lima, Cusco, Arequipa and Trujillo, since 1650 show original characteristics that are advanced even to the European Baroque, as in the use of cushioned walls and solomonic columns (Church of la Compañía de Jesús, Cusco; Basilica and Convent of San Francisco, Lima). Other countries include: the Metropolitan Cathedral of Sucre in Bolivia; Cathedral Basilica of Esquipulas in Guatemala; Tegucigalpa Cathedral in Honduras; León Cathedral in Nicaragua; the Church of la Compañía de Jesús in Quito, Ecuador; the Church of San Ignacio in Bogotá, Colombia; the Caracas Cathedral in Venezuela; the Cabildo of Buenos Aires in Argentina; the Church of Santo Domingo in Santiago, Chile; and Havana Cathedral in Cuba. It is also worth remembering the quality of the churches of the Spanish Jesuit Missions in Bolivia, Spanish Jesuit missions in Paraguay, the Spanish missions in Mexico and the Spanish Franciscan missions in California. In Brazil, as in the metropolis, Portugal, the architecture has a certain Italian influence, usually of a Borrominesque type, as can be seen in the Co-Cathedral of Recife (1784) and Church of Nossa Senhora da Glória do Outeiro in Rio de Janeiro (1739). In the region of Minas Gerais, highlighted the work of Aleijadinho, author of a group of churches that stand out for their curved planimetry, facades with concave-convex dynamic effects and a plastic treatment of all architectural elements (Church of São Francisco de Assis in Ouro Preto, 1765–1788). Baroque in the Spanish and Portuguese Colonial Asia In the Portuguese colonies of India (Goa, Daman and Diu) an architectural style of Baroque forms mixed with Hindu elements flourished, such as the Goa Cathedral and the Basilica of Bom Jesus of Goa, which houses the tomb of St. Francis Xavier. The set of churches and convents of Goa was declared a World Heritage Site in 1986. In the Philippines, that was part of the Spanish Empire for a long time, a large number of Baroque constructions are preserved, including the Baroque Churches of the Philippines that four of these, and the Baroque and Neoclassical city of Vigan, are both UNESCO World Heritage Sites. It was also very remarkable the Walled City of Manila (Intramuros). Other city with notable preserved Spanish-era Baroque is Tayabas. Painting Baroque painters worked deliberately to set themselves apart from the painters of the Renaissance and the Mannerism period after it. In their palette, they used intense and warm colours, and particularly made use of the primary colours red, blue and yellow, frequently putting all three in close proximity. They avoided the even lighting of Renaissance painting and used strong contrasts of light and darkness on certain parts of the picture to direct attention to the central actions or figures. In their composition, they avoided the tranquil scenes of Renaissance paintings, and chose the moments of the greatest movement and drama. Unlike the tranquil faces of Renaissance paintings, the faces in Baroque paintings clearly expressed their emotions. They often used asymmetry, with action occurring away from the centre of the picture, and created axes that were neither vertical nor horizontal, but slanting to the left or right, giving a sense of instability and movement. They enhanced this impression of movement by having the costumes of the personages blown by the wind, or moved by their own gestures. The overall impressions were movement, emotion and drama. Another essential element of baroque painting was allegory; every painting told a story and had a message, often encrypted in symbols and allegorical characters, which an educated viewer was expected to know and read. Early evidence of Italian Baroque ideas in painting occurred in Bologna, where Annibale Carracci, Agostino Carracci and Ludovico Carracci sought to return the visual arts to the ordered Classicism of the Renaissance. Their art, however, also incorporated ideas central the Counter-Reformation; these included intense emotion and religious imagery that appealed more to the heart than to the intellect. Another influential painter of the Baroque era was Michelangelo Merisi da Caravaggio. His realistic approach to the human figure, painted directly from life and dramatically spotlit against a dark background, shocked his contemporaries and opened a new chapter in the history of painting. Other major painters associated closely with the Baroque style include Artemisia Gentileschi, Elisabetta Sirani, Giovanna Garzoni, Guido Reni, Domenichino, Andrea Pozzo, and Paolo de Matteis in Italy; Francisco de Zurbarán and Diego Velázquez in Spain; Adam Elsheimer in Germany; and Nicolas Poussin and Georges de La Tour in France (though Poussin spent most of his working life in Italy). Poussin and La Tour adopted a "classical" Baroque style with less focus on emotion and greater attention to the line of the figures in the painting than to colour. Peter Paul Rubens was the most important painter of the Flemish Baroque style. Rubens' highly charged compositions reference erudite aspects of classical and Christian history. His unique and immensely popular Baroque style emphasised movement, colour, and sensuality, which followed the immediate, dramatic artistic style promoted in the Counter-Reformation. Rubens specialized in making altarpieces, portraits, landscapes, and history paintings of mythological and allegorical subjects. One important domain of Baroque painting was Quadratura, or paintings in trompe-l'œil, which literally "fooled the eye". These were usually painted on the stucco of ceilings or upper walls and balustrades, and gave the impression to those on the ground looking up were that they were seeing the heavens populated with crowds of angels, saints and other heavenly figures, set against painted skies and imaginary architecture. In Italy, artists often collaborated with architects on interior decoration; Pietro da Cortona was one of the painters of the 17th century who employed this illusionist way of painting. Among his most important commissions were the frescoes he painted for the Palace of the Barberini family (1633–39), to glorify the reign of Pope Urban VIII. Pietro da Cortona's compositions were the largest decorative frescoes executed in Rome since the work of Michelangelo at the Sistine Chapel. François Boucher was an important figure in the more delicate French Rococo style, which appeared during the late Baroque period. He designed tapestries, carpets and theatre decoration as well as painting. His work was extremely popular with Madame Pompadour, the Mistress of King Louis XV. His paintings featured mythological romantic, and mildly erotic themes. Spanish Americas In the Spanish Americas, the first influences were from Sevillan Tenebrism, mainly from Zurbarán —some of whose works are still preserved in Mexico and Peru— as can be seen in the work of the Mexicans José Juárez and Sebastián López de Arteaga, and the Bolivian Melchor Pérez de Holguín. The Cusco School of painting arose after the arrival of the Italian painter Bernardo Bitti in 1583, who introduced Mannerism in the Americas. It highlighted the work of Luis de Riaño, disciple of the Italian Angelino Medoro, author of the murals of the Church of San Pedro of Andahuaylillas. It also highlighted the Indian (Quechua) painters Diego Quispe Tito and Basilio Santa Cruz Pumacallao, as well as Marcos Zapata, author of the fifty large canvases that cover the high arches of the Cathedral of Cusco. In Ecuador, the Quito School was formed, mainly represented by the mestizo Miguel de Santiago and the criollo Nicolás Javier de Goríbar. In the 18th century sculptural altarpieces began to be replaced by paintings, developing notably the Baroque painting in the Americas. Similarly, the demand for civil works, mainly portraits of the aristocratic classes and the ecclesiastical hierarchy, grew. The main influence was the Murillesque, and in some cases – as in the criollo Cristóbal de Villalpando – that of Valdés Leal. The painting of this era has a more sentimental tone, with sweet and softer shapes. It highlight Gregorio Vásquez de Arce in Colombia, and Juan Rodríguez Juárez and Miguel Cabrera in Mexico. Sculpture The dominant figure in baroque sculpture was Gian Lorenzo Bernini. Under the patronage of Pope Urban VIII, he made a remarkable series of monumental statues of saints and figures whose faces and gestures vividly expressed their emotions, as well as portrait busts of exceptional realism, and highly decorative works for the Vatican such as the imposing Chair of St. Peter beneath the dome in St. Peter's Basilica. In addition, he designed fountains with monumental groups of sculpture to decorate the major squares of Rome. Baroque sculpture was inspired by ancient Roman statuary, particularly by the famous first century CE statue of Laocoön, which was unearthed in 1506 and put on display in the gallery of the Vatican. When he visited Paris in 1665, Bernini addressed the students at the academy of painting and sculpture. He advised the students to work from classical models, rather than from nature. He told the students, "When I had trouble with my first statue, I consulted the Antinous like an oracle." That Antinous statue is known today as the Hermes of the Museo Pio-Clementino. Notable late French baroque sculptors included Étienne Maurice Falconet and Jean Baptiste Pigalle. Pigalle was commissioned by Frederick the Great to make statues for Frederick's own version of Versailles at Sanssouci in Potsdam, Germany. Falconet also received an important foreign commission, creating the famous statue of Peter the Great on horseback found in St. Petersburg. In Spain, the sculptor Francisco Salzillo worked exclusively on religious themes, using polychromed wood. Some of the finest baroque sculptural craftsmanship was found in the gilded stucco altars of churches of the Spanish colonies of the New World, made by local craftsmen; examples include the Rosary Chapel of the Church of Santo Domingo in Oaxaca (Mexico), 1724–1731. Furniture The main motifs used are: horns of plenty, festoons, baby angels, lion heads holding a metal ring in their mouths, female faces surrounded by garlands, oval cartouches, acanthus leaves, classical columns, caryatids, pediments, and other elements of Classical architecture sculpted on some parts of pieces of furniture, baskets with fruits or flowers, shells, armour and trophies, heads of Apollo or Bacchus, and C-shaped volutes. During the first period of the reign of Louis XIV, furniture followed the previous style of Louis XIII, and was massive, and profusely decorated with sculpture and gilding. After 1680, thanks in large part to the furniture designer André Charles Boulle, a more original and delicate style appeared, sometimes known as Boulle work. It was based on the inlay of ebony and other rare woods, a technique first used in Florence in the 15th century, which was refined and developed by Boulle and others working for Louis XIV. Furniture was inlaid with plaques of ebony, copper, and exotic woods of different colors. New and often enduring types of furniture appeared; the commode, with two to four drawers, replaced the old coffre, or chest. The canapé, or sofa, appeared, in the form of a combination of two or three armchairs. New kinds of armchairs appeared, including the fauteuil en confessionale or "Confessional armchair", which had padded cushions ions on either side of the back of the chair. The console table also made its first appearance; it was designed to be placed against a wall. Another new type of furniture was the table à gibier, a marble-topped table for holding dishes. Early varieties of the desk appeared; the Mazarin desk had a central section set back, placed between two columns of drawers, with four feet on each column. Music The term Baroque is also used to designate the style of music composed during a period that overlaps with that of Baroque art. The first uses of the term 'baroque' for music were criticisms. In an anonymous, satirical review of the première in October 1733 of Rameau's Hippolyte et Aricie, printed in the Mercure de France in May 1734, the critic implied that the novelty of this opera was "du barocque," complaining that the music lacked coherent melody, was filled with unremitting dissonances, constantly changed key and meter, and speedily ran through every compositional device. Jean-Jacques Rousseau, who was a musician and noted composer as well as philosopher, made a very similar observation in 1768 in the famous Encyclopédie of Denis Diderot: "Baroque music is that in which the harmony is confused, and loaded with modulations and dissonances. The singing is harsh and unnatural, the intonation difficult, and the movement limited. It appears that term comes from the word 'baroco' used by logicians." Common use of the term for the music of the period began only in 1919, by Curt Sachs, and it was not until 1940 that it was first used in English in an article published by Manfred Bukofzer. The baroque was a period of musical experimentation and innovation. New forms were invented, including the concerto and sinfonia. Opera was born in Italy at the end of the 16th century (with Jacopo Peri's mostly lost Dafne, produced in Florence in 1598) and soon spread through the rest of Europe: Louis XIV created the first Royal Academy of Music, In 1669, the poet Pierre Perrin opened an academy of opera in Paris, the first opera theatre in France open to the public, and premiered Pomone, the first grand opera in French, with music by Robert Cambert, with five acts, elaborate stage machinery, and a ballet. Heinrich Schütz in Germany, Jean-Baptiste Lully in France, and Henry Purcell in England all helped to establish their national traditions in the 17th century. Several new instruments, including the piano, were introduced during this period. The invention of the piano is credited to Bartolomeo Cristofori (1655–1731) of Padua, Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany, as the Keeper of the Instruments. Cristofori named the instrument un cimbalo di cipresso di piano e forte ("a keyboard of cypress with soft and loud"), abbreviated over time as pianoforte, fortepiano, and later, simply, piano.

The style of court dance was brought to France by Marie de Medici, and in the beginning the members of the court themselves were the dancers. Louis XIV himself performed in public in several ballets. In March 1662, the Académie Royale de Danse, was founded by the King. It was the first professional dance school and company, and set the standards and vocabulary for ballet throughout Europe during the period. Theatre The Baroque period was a golden age for theatre in France and Spain; playwrights included Corneille, Racine and Molière in France; and Lope de Vega and Pedro Calderón de la Barca in Spain. During the Baroque period, the art and style of the theatre evolved rapidly, alongside the development of opera and of ballet. The design of newer and larger theatres, the invention the use of more elaborate machinery, the wider use of the proscenium arch, which framed the stage and hid the machinery from the audience, encouraged more scenic effects and spectacle. The Baroque had a Catholic and conservative character in Spain, following an Italian literary model during the Renaissance. The Hispanic Baroque theatre aimed for a public content with an ideal reality that manifested fundamental three sentiments: Catholic religion, monarchist and national pride and honour originating from the chivalric, knightly world. Two periods are known in the Baroque Spanish theatre, with the division occurring in 1630. The first period is represented chiefly by Lope de Vega, but also by Tirso de Molina, Gaspar Aguilar, Guillén de Castro, Antonio Mira de Amescua, Luis Vélez de Guevara, Juan Ruiz de Alarcón, Diego Jiménez de Enciso, Luis Belmonte Bermúdez, Felipe Godínez, Luis Quiñones de Benavente or Juan Pérez de Montalbán. The second period is represented by Pedro Calderón de la Barca and fellow dramatists Antonio Hurtado de Mendoza, Álvaro Cubillo de Aragón, Jerónimo de Cáncer, Francisco de Rojas Zorrilla, Juan de Matos Fragoso, Antonio Coello y Ochoa, Agustín Moreto, and Francisco Bances Candamo. These classifications are loose because each author had his own way and could occasionally adhere himself to the formula established by Lope. It may even be that Lope's "manner" was more liberal and structured than Calderón's. Lope de Vega introduced through his Arte nuevo de hacer comedias en este tiempo (1609) the new comedy. He established a new dramatic formula that broke the three Aristotle unities of the Italian school of poetry (action, time, and place) and a fourth unity of Aristotle which is about style, mixing of tragic and comic elements showing different types of verses and stanzas upon what is represented. Although Lope has a great knowledge of the plastic arts, he did not use it during the major part of his career nor in theatre or scenography. The Lope's comedy granted a second role to the visual aspects of the theatrical representation. Tirso de Molina, Lope de Vega, and Calderón were the most important play writers in Golden Era Spain. Their works, known for their subtle intelligence and profound comprehension of a person's humanity, could be considered a bridge between Lope's primitive comedy and the more elaborate comedy of Calderón. Tirso de Molina is best known for two works, The Convicted Suspicions and The Trickster of Seville, one of the first versions of the Don Juan myth. Upon his arrival to Madrid, Cosimo Lotti brought to the Spanish court the most advanced theatrical techniques of Europe. His techniques and mechanic knowledge were applied in palace exhibitions called "Fiestas" and in lavish exhibitions of rivers or artificial fountains called "Naumaquias". He was in charge of styling the Gardens of Buen Retiro, of Zarzuela, and of Aranjuez and the construction of the theatrical building of Coliseo del Buen Retiro. Lope's formulas begin with a verse that it unbefitting of the palace theatre foundation and the birth of new concepts that begun the careers of some play writers like Calderón de la Barca. Marking the principal innovations of the New Lopesian Comedy, Calderón's style marked many differences, with a great deal of constructive care and attention to his internal structure. Calderón's work is in formal perfection and a very lyric and symbolic language. Liberty, vitality and openness of Lope gave a step to Calderón's intellectual reflection and formal precision. In his comedy it reflected his ideological and doctrine intentions in above the passion and the action, the work of Autos sacramentales achieved high ranks. The genre of Comedia is political, multi-artistic and in a sense hybrid. The poetic text interweaved with Medias and resources originating from architecture, music and painting freeing the deception that is in the Lopesian comedy was made up from the lack of scenery and engaging the dialogue of action. The best known German playwright was Andreas Gryphius, who used the Jesuit model of the Dutch Joost van den Vondel and Pierre Corneille. There was also Johannes Velten who combined the traditions of the English comedians and the commedia dell'arte with the classic theatre of Corneille and Molière. His touring company was perhaps the most significant and important of the 17th century. Spanish colonial Americas Following the evolution marked from Spain, at the end of the 16th century, the companies of comedians, essentially transhumant, began to professionalize. With professionalization came regulation and censorship: as in Europe, the theatre oscillated between tolerance and even government protection and rejection (with exceptions) or persecution by the Church. The theatre was useful to the authorities as an instrument to disseminate the desired behavior and models, respect for the social order and the monarchy, school of religious dogma. The corrales were administered for the benefit of hospitals that shared the benefits of the representations. The itinerant companies (or "of the league"), who carried the theatre in improvised open-air stages by the regions that did not have fixed locals, required a viceregal license to work, whose price or pinción was destined to alms and works pious. For companies that worked stably in the capitals and major cities, one of their main sources of income was participation in the festivities of the Corpus Christi, which provided them with not only economic benefits, but also recognition and social prestige. The representations in the viceregal palace and the mansions of the aristocracy, where they represented both the comedies of their repertoire and special productions with great lighting effects, scenery, and stage, were also an important source of well-paid and prestigious work. Born in the Viceroyalty of New Spain but later settled in Spain, Juan Ruiz de Alarcón is the most prominent figure in the Baroque theatre of New Spain. Despite his accommodation to Lope de Vega's new comedy, his "marked secularism", his discretion and restraint, and a keen capacity for "psychological penetration" as distinctive features of Alarcón against his Spanish contemporaries have been noted. Noteworthy among his works La verdad sospechosa, a comedy of characters that reflected his constant moralizing purpose. The dramatic production of Sor Juana Inés de la Cruz places her as the second figure of the Spanish-American Baroque theatre. It is worth mentioning among her works the auto sacramental El divino Narciso and the comedy Los empeños de una casa. Gardens The Baroque garden, also known as the jardin à la française or French formal garden, first appeared in Rome in the 16th century, and then most famously in France in the 17th century in the gardens of Vaux le Vicomte and the Palace of Versailles. Baroque gardens were built by Kings and princes in Germany, the Netherlands, Austria, Spain, Poland, Italy and Russia until the mid-18th century, when they began to be remade into by the more natural English landscape garden. The purpose of the baroque garden was to illustrate the power of man over nature, and the glory of its builder, Baroque gardens were laid out in geometric patterns, like the rooms of a house. They were usually best seen from the outside and looking down, either from a chateau or terrace. The elements of a baroque garden included parterres of flower beds or low hedges trimmed into ornate Baroque designs, and straight lanes and alleys of gravel which divided and crisscrossed the garden. Terraces, ramps, staircases and cascades were placed where there were differences of elevation, and provided viewing points. Circular or rectangular ponds or basins of water were the settings for fountains and statues. Bosquets or carefully trimmed groves or lines of identical trees, gave the appearance of walls of greenery and were backdrops for statues. On the edges, the gardens usually had pavilions, orangeries and other structures where visitors could take shelter from the sun or rain. Baroque gardens required enormous numbers of gardeners, continual trimming, and abundant water. In the later part of the Baroque period, the formal elements began to be replaced with more natural features, including winding paths, groves of varied trees left to grow untrimmed; rustic architecture and picturesque structures, such as Roman temples or Chinese pagodas, as well as "secret gardens" on the edges of the main garden, filled with greenery, where visitors could read or have quiet conversations. By the mid-18th century most of the Baroque gardens were partially or entirely transformed into variations of the English landscape garden. Besides Versailles and Vaux-le-Vicomte, Celebrated baroque gardens still retaining much of their original appearance include the Royal Palace of Caserta near Naples; Nymphenburg Palace and Augustusburg and Falkenlust Palaces, Brühl in Germany; Het Loo Palace in the Netherlands; the Belvedere Palace in Vienna; the Royal Palace of La Granja de San Ildefonso in Spain; and Peterhof Palace in St. Petersburg, Russia. Differences between Rococo and Baroque The following are characteristics that Rococo has and Baroque has not: The partial abandonment of symmetry, everything being composed of graceful lines and curves, similar to the Art Nouveau ones The huge quantity of asymmetrical curves and C-shaped volutes The very wide use of flowers in ornamentation, an example being festoons made of flowers Chinese and Japanese motifs Warm pastel colours (whitish-yellow, cream-coloured, pearl greys, very light blues) End of the style, condemnation, and academic rediscovery Madame de Pompadour, the mistress of Louis XV, contributed to the decline of the baroque and rococo style. In 1750 she sent her nephew, Abel-François Poisson de Vandières, on a two-year mission to study artistic and archeological developments in Italy. He was accompanied by several artists, including the engraver Nicolas Cochin and the architect Soufflot. They returned to Paris with a passion for classical art. Vandiéres became the Marquis of Marigny, and was named Royal Director of buildings in 1754. He turned official French architecture toward the neoclassical. Cochin became an important art critic; he denounced the petit style of Boucher, and called for a grand style with a new emphasis on antiquity and nobility in the academies of painting of architecture. The pioneer German art historian and archeologist Johann Joachim Winckelmann also condemned the baroque style, and praised the superior values of classical art and architecture. By the 19th century, Baroque was a target for ridicule and criticism. The neoclassical critic Francesco Milizia wrote: "Borrominini in architecture, Bernini in sculpture, Pietro da Cortona in painting...are a plague on good taste, which infected a large number of artists." In the 19th century, criticism went even further; the British critic John Ruskin declared that baroque sculpture was not only bad, but also morally corrupt. The Swiss-born art historian Heinrich Wölfflin (1864–1945) started the rehabilitation of the word Baroque in his Renaissance und Barock (1888); Wölfflin identified the Baroque as "movement imported into mass", an art antithetic to Renaissance art. He did not make the distinctions between Mannerism and Baroque that modern writers do, and he ignored the later phase, the academic Baroque that lasted into the 18th century. Baroque art and architecture became fashionable in the interwar period, and has largely remained in critical favor. The term "Baroque" may still be used, usually pejoratively, describing works of art, craft, or design that are thought to have excessive ornamentation or complexity of line. Baroque Revival art The end of the 19th century was a golden age for revival styles, including Baroque Revival or Neo-Baroque. In addition to its practical (protective) function, the face also has aesthetic and architectural purposes. It mirrors the predominant styles of a certain era. Ornaments are the most common "ornaments" of buildings. The ornaments used in 17th-18th century architecture are reused at Baroque Revival buildings, including: horns of plenty, festoons, baby angels, female or male mascarons, oval cartouches, acanthus leaves, classical columns, caryatids, pediments and other elements of Greco-Roman architecture. Most Baroque revival buildings have mansard roofs, usually blue or sometimes black, with oval or dormer windows. Some of the houses is this style have cartouche-shaped oculus windows, usually with a mascaron at their top or bottom. In France and Romania, many of the entrances have awnings (; ), made of glass and metal, usually in a seashell-shape. In these two counties, especially in Romania, Neo-Baroque was sometimes combined with Art Nouveau. Beaux-Arts buildings from the late 1890s and early 1900s are very good examples of Baroque Revival architecture. The most famous Neo-Baroque building in Paris are: the Pavillon de Flore (part of the Palais du Louvre), the Palais Garnier, the Petit Palais, and the Grand Palais. Important architects of this style include Charles Garnier (1825–1898), Ferdinand Fellner (1847–1917), Hermann Helmer (1849–1919), and Ion D. Berindey (1871–1928). In decorative arts, Baroque Revival is usually known as the Napoleon III style or Second Empire style. Objects in this style was very appreciated in late 1890s and early 1900s Romania, many of them being brought from France or Austria. One of the main influence was the Louis XVI style, or French neoclassicism, which was preferred by the Empress Eugénie. Her rooms at the Tuileries Palace and other Places were decorated in this style. Other influences include French Renaissance and the Henry II style, which were popular influences on chests and cabinets, buffets and credences, which were massive and built like small cathedrals, decorated with columns, pediments, cartouches, mascarons, and carved angels and chimeras. They were usually constructed of walnut or oak, or sometimes of poirier stained to resemble ebony.

Harry Lillis "Bing" Crosby Jr. (May 3, 1903 – October 14, 1977) was an American singer and actor. The first multimedia star, he was one of the most popular and influential musical artists of the 20th century worldwide. He was a leader in record sales, radio ratings, and motion picture grosses from 1926 to 1977. He made over 70 feature films and recorded more than 1,600 songs. His early career coincided with recording innovations that allowed him to develop an intimate singing style that influenced many male singers who followed, such as Perry Como, Frank Sinatra, Dean Martin, Dick Haymes, Elvis Presley, and John Lennon. Yank magazine said that he was "the person who had done the most for the morale of overseas servicemen" during World War II. In 1948, American polls declared him the "most admired man alive", ahead of Jackie Robinson and Pope Pius XII. In 1948, Music Digest estimated that his recordings filled more than half of the 80,000 weekly hours allocated to recorded radio music. Crosby won the Academy Award for Best Actor for his performance in Going My Way (1944) and was nominated for its sequel, The Bells of St. Mary's (1945), opposite Ingrid Bergman, becoming the first of six actors to be nominated twice for playing the same character. In 1963, Crosby received the first Grammy Global Achievement Award. He is one of 33 people to have three stars on the Hollywood Walk of Fame, in the categories of motion pictures, radio, and audio recording. He was also known for his collaborations with his friend Bob Hope, starring in the Road to... films from 1940 to 1962. Crosby influenced the development of the post World War II recording industry. After seeing a demonstration of a German broadcast quality reel-to-reel tape recorder brought to America by John T. Mullin, he invested $50,000 in California electronics company Ampex to build copies. He then persuaded ABC to allow him to tape his shows. He became the first performer to prerecord his radio shows and master his commercial recordings onto magnetic tape. Through the medium of recording, he constructed his radio programs with the same directorial tools and craftsmanship (editing, retaking, rehearsal, time shifting) used in motion picture production, a practice that became industry standard. In addition to his work with early audio tape recording, he helped finance the development of videotape, bought television stations, bred racehorses, and co-owned the Pittsburgh Pirates baseball team, during which time the team won two World Series (1960 and 1971). Early life Crosby was born on May 3, 1903 in Tacoma, Washington, in a house his father built at 1112 North J Street. In 1906, his family moved to Spokane in Eastern Washington state, where he was raised. In 1913, his father built a house at 508 E. Sharp Avenue. The house sits on the campus of his alma mater, Gonzaga University. It functions today as a museum housing over 200 artifacts from his life and career, including his Oscar. He was the fourth of seven children: brothers Laurence Earl "Larry" (1895–1975), Everett Nathaniel (1896–1966), Edward John "Ted" (1900–1973), and George Robert "Bob" (1913–1993); and two sisters, Catherine Cordelia (1904–1974) and Mary Rose (1906–1990). His parents were Harry Lowe Crosby (1870–1950), a bookkeeper, and Catherine Helen "Kate" (née Harrigan; 1873–1964). His mother was a second generation Irish-American. His father was of Scottish and English descent; an ancestor, Simon Crosby, emigrated from England to New England in the 1630s during the Puritan migration to New England. Through another line, also on his father's side, Crosby is descended from Mayflower passenger William Brewster (c. 1567 – April 10, 1644). On November 8, 1937, after Lux Radio Theatre's adaptation of She Loves Me Not, Joan Blondell asked Crosby how he got his nickname: As it happens, that story was pure whimsy for dramatic effect; the Associated Press had reported as early as February 1932—as would later be confirmed by both Bing himself and his biographer Charles Thompson—that it was in fact a neighbor—Valentine Hobart, circa 1910—who had named him "Bingo from Bingville" after a comic feature in the local paper called The Bingville Bugle which the young Harry liked. In time, Bingo got shortened to Bing. In 1917, Crosby took a summer job as property boy at Spokane's Auditorium, where he witnessed some of the acts of the day, including Al Jolson, who held him spellbound with ad-libbing and parodies of Hawaiian songs. He later described Jolson's delivery as "electric". Crosby graduated from Gonzaga High School (today's Gonzaga Preparatory School) in 1920 and enrolled at Gonzaga University. He attended Gonzaga for three years but did not earn a degree. As a freshman, he played on the university's baseball team. The university granted him an honorary doctorate in 1937. Today, Gonzaga University houses a large collection of photographs, correspondence, and other material related to Crosby. Performance career Early years In 1923 Crosby was invited to join a new band composed of high-school students a few years younger than himself. Al and Miles Rinker (brothers of singer Mildred Bailey), James Heaton, Claire Pritchard and Robert Pritchard, along with drummer Crosby, formed the Musicaladers, who performed at dances both for high school students and club-goers. The group performed on Spokane radio station KHQ, but disbanded after two years. Crosby and Al Rinker obtained work at the Clemmer Theatre in Spokane (now known as the Bing Crosby Theater). Crosby was initially a member of a vocal trio called The Three Harmony Aces with Al Rinker accompanying on piano from the pit, to entertain between the films. Crosby and Al continued at the Clemmer Theatre for several months often with three other men – Wee Georgie Crittenden, Frank McBride and Lloyd Grinnell – and they were billed The Clemmer Trio or The Clemmer Entertainers depending who performed. In October 1925, Crosby and Rinker decided to seek fame in California. They traveled to Los Angeles, where Bailey introduced them to her show business contacts. The Fanchon and Marco Time Agency hired them for thirteen weeks for the revue The Syncopation Idea starting at the Boulevard Theater in Los Angeles and then on the Loew's circuit. They each earned $75 a week. As minor parts of The Syncopation Idea Crosby and Rinker started to develop as entertainers. They had a lively style that was popular with college students. After The Syncopation Idea closed, they worked in the Will Morrissey Music Hall Revue. They honed their skills with Morrissey. When they got a chance to present an independent act, they were spotted by a member of the Paul Whiteman organization. Whiteman needed something different to break up his musical selections, and Crosby and Rinker filled this requirement. After less than a year in show business, they were attached to one of the biggest names. Hired for $150 a week in 1926, they debuted with Whiteman on December 6 at the Tivoli Theatre in Chicago. Their first recording, in October 1926, was "I've Got the Girl" with Don Clark's Orchestra, but the Columbia-issued record was inadvertently recorded at a slow speed, which increased the singers' pitch when played at 78 rpm. Throughout his career, Crosby often credited Bailey for getting him his first important job in the entertainment business. The Rhythm Boys Success with Whiteman was followed by disaster when they reached New York. Whiteman considered letting them go. However, the addition of pianist and aspiring songwriter Harry Barris made the difference, and The Rhythm Boys were born. The additional voice meant they could be heard more easily in large New York theaters. Crosby gained valuable experience on tour for a year with Whiteman and performing and recording with Bix Beiderbecke, Jack Teagarden, Tommy Dorsey, Jimmy Dorsey, Eddie Lang, and Hoagy Carmichael. He matured as a performer and was in demand as a solo singer. Crosby became the star attraction of the Rhythm Boys. In 1928 he had his first number one hit, a jazz-influenced rendition of "Ol' Man River". In 1929, the Rhythm Boys appeared in the film King of Jazz with Whiteman, but Crosby's growing dissatisfaction with Whiteman led to the Rhythm Boys leaving his organization. They joined the Gus Arnheim Orchestra, performing nightly in the Coconut Grove of the Ambassador Hotel. Singing with the Arnheim Orchestra, Crosby's solos began to steal the show while the Rhythm Boys' act gradually became redundant. Harry Barris wrote several of Crosby's hits, including "At Your Command", "I Surrender Dear", and "Wrap Your Troubles in Dreams". When Mack Sennett signed Crosby to a solo recording contract in 1931, a break with the Rhythm Boys became almost inevitable. Crosby married Dixie Lee in September 1930. After a threat of divorce in March 1931, he applied himself to his career. Success as a solo singer 15 Minutes with Bing Crosby, his nationwide solo radio debut, began broadcasting on September 2, 1931. The weekly broadcast made him a hit. Before the end of the year, he with both Brunswick Records and CBS Radio. "Out of Nowhere", "Just One More Chance", "At Your Command" and "I Found a Million Dollar Baby (in a Five and Ten Cent Store)" were among the best selling songs of 1931. Ten of the top 50 songs of 1931 included Crosby with others or as a solo act. A "Battle of the Baritones" with singer Russ Columbo proved short-lived, replaced with the slogan "Bing Was King". Crosby played the lead in a series of musical comedy short films for Mack Sennett, signed with Paramount, and starred in his first full-length film 1932's The Big Broadcast (1932), the first of 55 films in which he received top billing. He would appear in 79 pictures. He signed a contract with Jack Kapp's new record company, Decca, in late 1934. His first commercial sponsor on radio was Cremo Cigars and his fame spread nationwide. After a long run in New York, he went back to Hollywood to film The Big Broadcast. His appearances, records, and radio work substantially increased his impact. The success of his first film brought him a contract with Paramount, and he began a pattern of making three films a year. He led his radio show for Woodbury Soap for two seasons while his live appearances dwindled. His records produced hits during the Depression when sales were down. Audio engineer Steve Hoffman stated, By the way, Bing actually saved the record business in 1934 when he agreed to support Decca founder Jack Kapp's crazy idea of lowering the price of singles from a dollar to 35 cents and getting a royalty for records sold instead of a flat fee. Bing's name and his artistry saved the recording industry. All the other artists signed to Decca after Bing did. Without him, Jack Kapp wouldn't have had a chance in hell of making Decca work and the Great Depression would have wiped out phonograph records for good. His social life was frantic. His first son Gary was born in 1933 with twin boys following in 1934. By 1936, he replaced his former boss, Paul Whiteman, as host of the weekly NBC radio program Kraft Music Hall, where he remained for the next ten years. "Where the Blue of the Night (Meets the Gold of the Day)", with his trademark whistling, became his theme song and signature tune. Crosby's vocal style helped take popular singing beyond the "belting" associated with Al Jolson and Billy Murray, who had been obligated to reach the back seats in New York theaters without the aid of a microphone. As music critic Henry Pleasants noted in The Great American Popular Singers, something new had entered American music, a style that might be called "singing in American" with conversational ease. This new sound led to the popular epithet crooner. Crosby admired Louis Armstrong for his musical ability, and the trumpet maestro was a formative influence on Crosby's singing style. When the two met, they became friends. In 1936, Crosby exercised an option in his Paramount contract to regularly star in an out-of-house film. Signing an agreement with Columbia for a single motion picture, Crosby wanted Armstrong to appear in a screen adaptation of The Peacock Feather that eventually became Pennies from Heaven. Crosby asked Harry Cohn, but Cohn had no desire to pay for the flight or to meet Armstrong's "crude, mob-linked but devoted manager, Joe Glaser". Crosby threatened to leave the film and refused to discuss the matter. Cohn gave in; Armstrong's musical scenes and comic dialogue extended his influence to the silver screen, creating more opportunities for him and other African Americans to appear in future films. Crosby also ensured behind the scenes that Armstrong received equal billing with his white co-stars. Armstrong appreciated Crosby's progressive attitudes on race, and often expressed gratitude for the role in later years. During World War II, Crosby made live appearances before American troops who had been fighting in the European Theater. He learned how to pronounce German from written scripts and read propaganda broadcasts intended for German forces. The nickname "Der Bingle" was common among Crosby's German listeners and came to be used by his English-speaking fans. In a poll of U.S. troops at the close of World War II, Crosby topped the list as the person who had done the most for G.I. morale, ahead of President Franklin D. Roosevelt, General Dwight Eisenhower, and Bob Hope. The June 18, 1945 issue of Life magazine stated, "America's number one star, Bing Crosby, has won more fans, made more money than any entertainer in history. Today he is a kind of national institution." "In all, 60,000,000 Crosby discs have been marketed since he made his first record in 1931. His biggest best seller is "White Christmas" 2,000,000 impressions of which have been sold in the U.S. and 250,000 in Great Britain." "Nine out of ten singers and bandleaders listen to Crosby's broadcasts each Thursday night and follow his lead. The day after he sings a song over the air – any song – some 50,000 copies of it are sold throughout the U.S. Time and again Crosby has taken some new or unknown ballad, has given it what is known in trade circles as the 'big goose' and made it a hit single-handed and overnight... Precisely what the future holds for Crosby neither his family nor his friends can conjecture. He has achieved greater popularity, made more money, attracted vaster audiences than any other entertainer in history. And his star is still in the ascendant. His contract with Decca runs until 1955. His contract with Paramount runs until 1954. Records which he made ten years ago are selling better than ever before. The nation's appetite for Crosby's voice and personality appears insatiable. To soldiers overseas and to foreigners he has become a kind of symbol of America, of the amiable, humorous citizen of a free land. Crosby, however, seldom bothers to contemplate his future. For one thing, he enjoys hearing himself sing, and if ever a day should dawn when the public wearies of him, he will complacently go right on singing—to himself." White Christmas The biggest hit song of Crosby's career was his recording of Irving Berlin's "White Christmas", which he introduced on a Christmas Day radio broadcast in 1941. A copy of the recording from the radio program is owned by the estate of Bing Crosby and was loaned to CBS Sunday Morning for their December 25, 2011 program. The song appeared in his film Holiday Inn (1942). His record hit the charts on October 3, 1942, and rose to number 1 on October 31, where it stayed for 11 weeks. A holiday perennial, the song was repeatedly re-released by Decca, charting another sixteen times. It topped the charts again in 1945 and a third time in January 1947. The song remains the bestselling single of all time. According to Guinness World Records, his recording of "White Christmas", has sold over 50 million copies around the world. His recording was so popular that he was obliged to re-record it in 1947 using the same musicians and backup singers; the original 1942 master had become damaged due to its frequent use in pressing additional singles. In 1977, after Crosby died, the song was re-released and reached No. 5 in the UK Singles Chart. Crosby was dismissive of his role in the song's success, saying "a jackdaw with a cleft palate could have sung it successfully". Motion pictures In the wake of a solid decade of headlining mainly smash hit musical comedy films in the 1930s, Crosby starred with Bob Hope and Dorothy Lamour in six of the seven Road to musical comedies between 1940 and 1962 (Lamour was replaced with Joan Collins in The Road to Hong Kong and limited to a lengthy cameo), cementing Crosby and Hope as an on-and-off duo, despite never declaring themselves a "team" in the sense that Laurel and Hardy or Martin and Lewis (Dean Martin and Jerry Lewis) were teams. The series consists of Road to Singapore (1940), Road to Zanzibar (1941), Road to Morocco (1942), Road to Utopia (1946), Road to Rio (1947), Road to Bali (1952), and The Road to Hong Kong (1962). When they appeared solo, Crosby and Hope frequently made note of the other in a comically insulting fashion. They performed together countless times on stage, radio, film, and television, and made numerous brief and not so brief appearances together in movies aside from the "Road" pictures, Variety Girl (1947) being an example of lengthy scenes and songs together along with billing. In the 1949 Disney animated film The Adventures of Ichabod and Mr. Toad, Crosby provided the narration and song vocals for The Legend of Sleepy Hollow segment. In 1960, he starred in High Time, a collegiate comedy with Fabian Forte and Tuesday Weld that predicted the emerging gap between him and the new younger generation of musicians and actors who had begun their careers after World War II. The following year, Crosby and Hope reunited for one more Road movie, The Road to Hong Kong, which teamed them up with the much younger Joan Collins and Peter Sellers. Collins was used in place of their longtime partner Dorothy Lamour, whom Crosby felt was getting too old for the role, though Hope refused to do the film without her, and she instead made a lengthy and elaborate cameo appearance. Shortly before his death in 1977, he had planned another Road film in which he, Hope, and Lamour search for the Fountain of Youth. He won an Academy Award for Best Actor for Going My Way in 1944 and was nominated for the 1945 sequel, The Bells of St. Mary's. He received critical acclaim for his performance as an alcoholic entertainer in The Country Girl and received his third Academy Award nomination. Television The Fireside Theater (1950) was his first television production. The series of 26-minute shows was filmed at Hal Roach Studios rather than performed live on the air. The "telefilms" were syndicated to individual television stations. He was a frequent guest on the musical variety shows of the 1950s and 1960s, appearing on various variety shows as well as numerous late-night talk shows and his own highly rated specials. Bob Hope memorably devoted one of his monthly NBC specials to his long intermittent partnership with Crosby titled "On the Road With Bing". Crosby was associated with ABC's The Hollywood Palace as the show's first and most frequent guest host and appeared annually on its Christmas edition with his wife Kathryn and his younger children, and continued after The Hollywood Palace was eventually canceled. In the early 1970s, he made two late appearances on the Flip Wilson Show, singing duets with the comedian. His last TV appearance was a Christmas special, Merrie Olde Christmas, taped in London in September 1977 and aired weeks after his death. It was on this special that he recorded a duet of "The Little Drummer Boy" and "Peace on Earth" with rock musician David Bowie. Their duet was released in 1982 as a single 45-rpm record and reached No. 3 in the UK singles charts. It has since become a staple of holiday radio and the final popular hit of Crosby's career. At the end of the 20th century, TV Guide listed the Crosby-Bowie duet one of the 25 most memorable musical moments of 20th-century television. Bing Crosby Productions, affiliated with Desilu Studios and later CBS Television Studios, produced a number of television series, including Crosby's own unsuccessful ABC sitcom The Bing Crosby Show in the 1964–1965 season (with co-stars Beverly Garland and Frank McHugh). The company produced two ABC medical dramas, Ben Casey (1961–1966) and Breaking Point (1963–1964), the popular Hogan's Heroes (1965–1971) military comedy on CBS, as well as the lesser-known show Slattery's People (1964–1965). Singing style and vocal characteristics Crosby was one of the first singers to exploit the intimacy of the microphone rather than use the deep, loud vaudeville style associated with Al Jolson. He was, by his own definition, a "phraser", a singer who placed equal emphasis on both the lyrics and the music. Paul Whiteman's hiring of Crosby, with phrasing that echoed jazz, particularly his bandmate Bix Beiderbecke's trumpet, helped bring the genre to a wider audience. In the framework of the novelty-singing style of the Rhythm Boys, he bent notes and added off-tune phrasing, an approach that was rooted in jazz. He had already been introduced to Louis Armstrong and Bessie Smith before his first appearance on record. Crosby and Armstrong remained warm acquaintances for decades, occasionally singing together in later years, e.g. "Now You Has Jazz" in the film High Society (1956). During the early portion of his solo career (about 1931–1934), Crosby's emotional, often pleading style of crooning was popular. But Jack Kapp, manager of Brunswick and later Decca, talked him into dropping many of his jazzier mannerisms in favor of a clear vocal style. Crosby credited Kapp for choosing hit songs, working with many other musicians, and most important, diversifying his repertoire into several styles and genres. Kapp helped Crosby have number one hits in Christmas music, Hawaiian music, and country music, and top-thirty hits in Irish music, French music, rhythm and blues, and ballads. Crosby elaborated on an idea of Al Jolson's: phrasing, or the art of making a song's lyric ring true. "I used to tell Sinatra over and over," said Tommy Dorsey, "there's only one singer you ought to listen to and his name is Crosby. All that matters to him is the words, and that's the only thing that ought to for you, too." Critic Henry Pleasants wrote: Career achievements Crosby's was among the most popular and successful musical acts of the 20th century. Billboard magazine used different methodologies during his career. But his chart success remains impressive: 396 chart singles, including roughly 41 number 1 hits. Crosby had separate charting singles every year between 1931 and 1954; the annual re-release of "White Christmas" extended that streak to 1957. He had 24 separate popular singles in 1939 alone. Statistician Joel Whitburn at Billboard determined that Crosby was America's most successful recording act of the 1930s and again in the 1940s. In 1960 Crosby was honored as "First Citzen of Record Industry" based on having sold 200 million discs. According to different sources he sold 300 million or even 500 million records worldwide. The single "White Christmas" sold over 50 million copies according to Guinness World Records. For fifteen years (1934, 1937, 1940, 1943–1954), Crosby was among the top ten acts in box-office sales, and for five of those years (1944–1948) he topped the world. He sang four Academy Award winning songs – "Sweet Leilani" (1937), "White Christmas" (1942), "Swinging on a Star" (1944), "In the Cool, Cool, Cool of the Evening" (1951) – and won the Academy Award for Best Actor for his role in Going My Way (1944). A survey in 2000 found that with 1,077,900,000 movie tickets sold, Crosby was the third most popular actor of all time, behind Clark Gable (1,168,300,000) and John Wayne (1,114,000,000). The International Motion Picture Almanac lists him in a tie for second-most years at number one on the All Time Number One Stars List with Clint Eastwood, Tom Hanks, and Burt Reynolds. His most popular film, White Christmas, grossed $30 million in 1954 ($ million in current value). He received 23 gold and platinum records, according to the book Million Selling Records. The Recording Industry Association of America did not institute its gold record certification program until 1958 when Crosby's record sales were low. Before 1958, gold records were awarded by record companies. Crosby charted 23 Billboard hits from 47 recorded songs with the Andrews Sisters, whose Decca record sales were second only to Crosby's throughout the 1940s. They were his most frequent collaborators on disc from 1939 to 1952, a partnership that produced four million-selling singles: "Pistol Packin' Mama", "Jingle Bells", "Don't Fence Me In", and "South America, Take it Away". They made one film appearance together in Road to Rio singing "You Don't Have to Know the Language", and sang together on the radio throughout the 1940s and 1950s. They appeared as guests on each other's shows and on Armed Forces Radio Service during and after World War II. The quartet's Top-10 Billboard hits from 1943 to 1945 include "The Vict'ry Polka", "There'll Be a Hot Time in the Town of Berlin (When the Yanks Go Marching In)", and "Is You Is or Is You Ain't (Ma' Baby?)" and helped morale of the American public. In 1962, Crosby was given the Grammy Lifetime Achievement Award. He has been inducted into the halls of fame for both radio and popular music. In 2007, he was inducted into the Hit Parade Hall of Fame and in 2008 the Western Music Hall of Fame. Popularity and influence Crosby's popularity around the world was such that in an interview with Dorothy Masuka, the best-selling African recording artist in Africa, she stated "Only Bing Crosby the famous American crooner sold more records than me in Africa." His great popularity throughout Africa led other African singers to emulate him, including Dolly Rathebe, Masuka, and Míriam Makeba, known locally as "The Bing Crosby of Africa" though she is female. Presenter Mike Douglas commented in a 1975 interview, "During my days in the Navy in World War II, I remember walking the streets of Calcutta, India, on the coast; it was a lonely night, so far from my home and from my new wife, Gen. I needed something to lift my spirits. As I passed a Hindu sitting on the corner of a street, I heard something surprisingly familiar. I came back to see the man playing one of those old Vitrolas, like those of RCA with the horn speaker. The man was listening to Bing Crosby sing, "Ac-Cent-Tchu-Ate The Positive". I stopped and smiled in grateful acknowledgment. The Hindu nodded and smiled back. The whole world knew and loved Bing Crosby." His popularity in India led many Hindu singers to imitate and emulate him, notably Kishore Kumar, considered the "Bing Crosby of India". Entrepreneurship According to Shoshana Klebanoff, Crosby became one of the richest men in the history of show business. He had investments in real estate, mines, oil wells, cattle ranches, race horses, music publishing, baseball teams, and television. He made a fortune from the Minute Maid Orange Juice Corporation, in which he was a principal stockholder. Role in early tape recording During the Golden Age of Radio, performers had to create their shows live, sometimes even redoing the program a second time for the West Coast time zone. Crosby had to do two live radio shows on the same day, three hours apart, for the East and West Coasts. Crosby's radio career took a significant turn in 1945, when he clashed with NBC over his insistence that he be allowed to pre-record his radio shows. (The live production of radio shows was also reinforced by the musicians' union and ASCAP, which wanted to ensure continued work for their members.) In On the Air: The Encyclopedia of Old-Time Radio, John Dunning wrote about German engineers having developed a tape recorder with a near-professional broadcast quality standard: Crosby's insistence eventually factored into the further development of magnetic tape sound recording and the radio industry's widespread adoption of it. He used his clout, both professionally and financially , for innovations in audio. But NBC and CBS refused to broadcast prerecorded radio programs. Crosby left the network and remained off the air for seven months, creating a legal battle with his sponsor Kraft that was settled out of court. He returned to broadcasting for the last 13 weeks of the 1945–1946 season. The Mutual Network, on the other hand, pre-recorded some of its programs as early as 1938 for The Shadow with Orson Welles. ABC was formed from the sale of the NBC Blue Network in 1943 after a federal antitrust suit and was willing to join Mutual in breaking the tradition. ABC offered Crosby $30,000 per week to produce a recorded show every Wednesday that would be sponsored by Philco. He would get an additional $40,000 from 400 independent stations for the rights to broadcast the 30-minute show, which was sent to them every Monday on three 16-inch (40-cm) lacquer discs that played ten minutes per side at 33 rpm. Murdo MacKenzie of Bing Crosby Enterprises had seen a demonstration of the German Magnetophon in June 1947—the same device that Jack Mullin had brought back from Radio Frankfurt with 50 reels of tape, at the end of the war. It was one of the magnetic tape recorders that BASF and AEG had built in Germany starting in 1935. The 6.5mm ferric-oxide-coated tape could record 20 minutes per reel of high-quality sound. Alexander M. Poniatoff ordered Ampex, which he founded in 1944, to manufacture an improved version of the Magnetophone. Crosby hired Mullin to start recording his Philco Radio Time show on his German-made machine in August 1947 using the same 50 reels of I.G. Farben magnetic tape that Mullin had found at a radio station at Bad Nauheim near Frankfurt while working for the U.S. Army Signal Corps. The advantage was editing. As Crosby wrote in his autobiography: Mullin's 1976 memoir of these early days of experimental recording agrees with Crosby's account: Crosby invested US $50,000 in Ampex with the intent to produce more machines. In 1948, the second season of Philco shows was recorded with the Ampex Model 200A and Scotch 111 tape from 3M. Mullin explained how one new broadcasting technique was invented on the Crosby show with these machines: Crosby started the tape recorder revolution in America. In his 1950 film Mr. Music, he is seen singing into an Ampex tape recorder that reproduced his voice better than anything else. Also quick to adopt tape recording was his friend Bob Hope. He gave one of the first Ampex Model 300 recorders to his friend, guitarist Les Paul, which led to Paul's invention of multitrack recording. His organization, the Crosby Research Foundation, held tape recording patents and developed equipment and recording techniques such as the laugh track that are still in use today. With Frank Sinatra, Crosby was one of the principal backers for the United Western Recorders studio complex in Los Angeles. Videotape development Mullin continued to work for Crosby to develop a videotape recorder (VTR). Television production was mostly live television in its early years, but Crosby wanted the same ability to record that he had achieved in radio. The Fireside Theater (1950) sponsored by Procter & Gamble, was his first television production. Mullin had not yet succeeded with videotape, so Crosby filmed the series of 26-minute shows at the Hal Roach Studios, and the "telefilms" were syndicated to individual television stations. Crosby continued to finance the development of videotape. Bing Crosby Enterprises gave the world's first demonstration of videotape recording in Los Angeles on November 11, 1951. Developed by John T. Mullin and Wayne R. Johnson since 1950, the device aired what were described as "blurred and indistinct" images, using a modified Ampex 200 tape recorder and standard quarter-inch (6.3 mm) audio tape moving at 360 inches (9.1m) per second. Television station ownership A Crosby-led group purchased station KCOP-TV, in Los Angeles, California, in 1954. NAFI Corporation and Crosby purchased television station KPTV in Portland, Oregon, for $4 million on September 1, 1959. In 1960, NAFI purchased KCOP from Crosby's group. In the early 1950s, Crosby helped establish the CBS television affiliate in his hometown of Spokane, Washington. He partnered with Ed Craney, who owned the CBS radio affiliate KXLY (AM) and built a television studio west of Crosby's alma mater, Gonzaga University. After it began broadcasting, the station was sold within a year to Northern Pacific Radio and Television Corporation. Thoroughbred horse racing Crosby was a fan of thoroughbred horse racing and bought his first racehorse in 1935. In 1937, he became a founding partner of the Del Mar Thoroughbred Club and a member of its board of directors. Operating from the Del Mar Racetrack at Del Mar, California, the group included millionaire businessman Charles S. Howard, who owned a successful racing stable that included Seabiscuit. Charles' son, Lindsay C. Howard, became one of Crosby's closest friends; Crosby named his son Lindsay after him, and would purchase his 40-room Hillsborough, California estate from Lindsay in 1965. Crosby and Lindsay Howard formed Binglin Stable to race and breed thoroughbred horses at a ranch in Moorpark in Ventura County, California. They also established the Binglin Stock Farm in Argentina, where they raced horses at Hipódromo de Palermo in Palermo, Buenos Aires. A number of Argentine-bred horses were purchased and shipped to race in the United States. On August 12, 1938, the Del Mar Thoroughbred Club hosted a $25,000 winner-take-all match race won by Charles S. Howard's Seabiscuit over Binglin's horse Ligaroti. In 1943, Binglin's horse Don Bingo won the Suburban Handicap at Belmont Park in Elmont, New York. The Binglin Stable partnership came to an end in 1953 as a result of a liquidation of assets by Crosby, who needed to raise enough funds to pay the hefty federal and state inheritance taxes on his deceased wife's estate. The Bing Crosby Breeders' Cup Handicap at Del Mar Racetrack is named in his honor. Sports Crosby had a keen interest in sports. In the 1930s, his friend and former college classmate, Gonzaga head coach, Mike Pecarovich, appointed Crosby as an assistant football coach. From 1946 until his death, he owned a 25% share of the Pittsburgh Pirates. Although he was passionate about the team, he was too nervous to watch the deciding Game 7 of the 1960 World Series, choosing to go to Paris with Kathryn and listen to its radio broadcast. Crosby had arranged for Ampex, another of his financial investments, to record the NBC telecast on kinescope. The game was one of the most famous in baseball history, capped off by Bill Mazeroski's walk-off home run that won the game for Pittsburgh. He apparently viewed the complete film just once, and then stored it in his wine cellar, where it remained undisturbed until it was discovered in December 2009. The restored broadcast was shown on MLB Network in December 2010. Crosby was also an avid golfer, and in 1978, he and Bob Hope were voted the Bob Jones Award, the highest honor given by the United States Golf Association in recognition of distinguished sportsmanship. He is a member of the World Golf Hall of Fame, having been inducted in 1978. In 1937, Crosby hosted the first 'Crosby Clambake' as it was popularly known, at Rancho Santa Fe Golf Club in Rancho Santa Fe, California, the event's location prior to World War II. Sam Snead won the first tournament, in which the first place check was for $500. After the war, the event resumed play in 1947 on golf courses in Pebble Beach, where it has been played ever since. Now the AT&T Pebble Beach Pro-Am, it has been a leading event in the world of professional golf. In 1950, he became the third person to win the William D. Richardson award, which is given to a non-professional golfer "who has consistently made an outstanding contribution to golf". Crosby first took up golf at age 12 as a caddy, dropped it, then started again in 1930 with some fellow cast members in Hollywood during the filming of The King of Jazz. Crosby was accomplished at the sport, with a two handicap. He competed in both the British and U.S. Amateur championships, was a five-time club champion at Lakeside Golf Club in Hollywood, and once made a hole-in-one on the 16th hole at Cypress Point. Crosby also was a keen fisherman especially in his younger days, but it was a pastime that he enjoyed throughout his life. In the summer of 1966, he spent a week as the guest of Lord Egremont, staying in Cockermouth and fishing on the River Derwent. His trip was filmed for The American Sportsman on ABC, although all did not go well at first as the salmon were not running. He did make up for it at the end of the week by catching a number of sea trout. Personal life Crosby was married twice. His first wife was actress and nightclub singer Dixie Lee, to whom he was married from 1930 until her death from ovarian cancer in 1952. They had four sons: Gary, twins Dennis and Phillip, and Lindsay. Smash-Up: The Story of a Woman (1947) is based on Lee's life. The Crosby family lived at 10500 Camarillo Street in North Hollywood for more than five years. After his wife died, Crosby had relationships with model Pat Sheehan (who married his son Dennis in 1958) and actresses Inger Stevens and Grace Kelly before marrying actress Kathryn Grant, who converted to Catholicism, in 1957. They had three children: Harry Lillis III (who played Bill in Friday the 13th), Mary (best known for portraying Kristin Shepard on TV's Dallas), and Nathaniel (the 1981 U.S. Amateur champion in golf). Particularly during the late 1930s and through the 1940s Bing Crosby's domestic life was tragically dominated by his wife's excessive drinking. His efforts to cure her with the help of specialists failed. Tired of Dixie's drinking, he even asked her for a divorce in January 1941. During the 1940s, Crosby consistently had difficulties trying to stay away from home while also trying to be there as much as possible for his children. Crosby had one confirmed extramarital affair between 1945 and the late 1940s, while married to his first wife Dixie. Actress Patricia Neal (who herself at the time was having an affair with the married Gary Cooper) wrote in her 1988 autobiography As I Am about a trip on a cruise ship to England with actress Joan Caulfield in 1948: In the most recent Crosby biography, Bing Crosby: Swinging on a Star; the War Years, 1940-1946, Gary Giddins published excerpts from an original diary of two sisters, Violet and Mary Barsa, who, as young women, used to stalk Crosby in New York City during December 1945 and January 1946 and who detailed their observations in the diary. The document reveals that during that time Crosby was indeed taking Joan Caulfield out to dinner, visited theaters and opera houses with her and that Caulfield and a person in her company entered the Waldorf Hotel where Crosby was staying. However, the document also clearly indicates that at their meetings a third person, on most instances Caulfield's mother, was present. In 1954, Joan Caulfield admitted to a relationship with a "top film star" who was a married man with children who at the end chose his wife and children over her. Joan's sister Betty Caulfield confirmed the romantic relationship between Joan and Bing Crosby. Despite being a Catholic, Crosby was seriously considering divorce in order to marry Caulfield. Either in December 1945 or January 1946 Crosby approached Cardinal Francis Spellman with his difficulties with dealing with his wife's alcoholism and his love for Caulfield and his plan to file for divorce. According to Betty Caulfield, Spellman told Crosby: "Bing, you are Father O'Malley and under no circumstances can Father O'Malley get a divorce." Around the same time, Crosby talked to his mother about his intentions and she protested. Ultimately, Crosby chose to end the relationship and to stay with his wife. Bing and Dixie reconciled and he continued trying to help her overcome her alcohol issues. Crosby reportedly had an alcohol problem between the late 1920s and early 1930s, but he got a handle on his drinking in 1931. According to biographer Giddins, during an argument about Gary Crosby's drinking, Crosby told his son in anger that smoking marijuana would be better than drinking so much alcohol, adding "It killed your mother". Crosby told Barbara Walters in a 1977 televised interview that he thought marijuana should be legalized. In December 1999 the New York Post published an article by Bill Hoffmann and Murray Weiss called Bing Crosby's Single Life which claimed that "recently published" FBI files on Crosby revealed that he had ties with figures in the Mafia since his youth. This information gets repeatedly reproduced in news articles until today. However, Crosby's FBI files actually got already published in 1992 and looking into these there is no indication that Bing Crosby had ties to the Mafia except for one major but accidental encounter in Chicago in 1929 which is not mentioned in the files but is told by Crosby himself in his as-told-to autobiography Call Me Lucky. In the over 280 pages of Crosby's FBI files all but one reference to organized crime or gambling dens are content of a few of the many threats that Bing Crosby received throughout his life. The comments made by FBI investigators in the memos discredited the claims made in the letters. In all the files there is only one single reference to a person associated with the Mafia. In a memorandum dated January 16, 1959 it is said: "The Salt Lake City Office has developed information indicating that Moe Dalitz received an invitation to join a deer hunting party at Bing Crosby's Elko, Nevada, ranch, together with the crooner, his Las Vegas dentist and several business associates." However, Crosby had already sold his Elko ranch a year earlier, in 1958, and it is doubtful how much he was really involved in that meeting. Crosby and his family lived in the San Francisco area for many years. In 1963, he and his wife Kathryn moved with their 3 young children from Los Angeles to a $175,000 10-bedroom Tudor estate in Hillsborough because they did not want to raise their children in Hollywood, according to son Nathaniel. This house went up for sale by its current owners in 2021 for $13.75 million. In 1965, the Crosbys moved to a larger, 40-room French-chateau style house on nearby Jackling Drive, where Kathryn Crosby continued to reside after Bing's death. This house served as a setting for some of the family's Minute Maid orange juice television commercials. After Crosby's death, his eldest son, Gary, wrote a highly critical memoir, Going My Own Way (1983), depicting his father as cruel, cold, remote, and physically and psychologically abusive. However, Bing Crosby's daughter Mary Crosby said in an interview that Gary Crosby told her the publishers had encouraged him to exaggerate his claims and he had written the book just for money. Crosby's younger son Phillip vociferously disputed his brother Gary's claims about their father. Around the time Gary published his claims, Phillip stated to the press that "Gary is a whining, bitching crybaby, walking around with a two-by-four on his shoulder and just daring people to nudge it off." Nevertheless, Phillip did not deny that Crosby believed in corporal punishment. In an interview with People magazine, Phillip stated that "we never got an extra whack or a cuff we didn't deserve". During an interview in 1999 by the Globe, Phillip said: However, Dennis and Lindsay Crosby confirmed that Bing sometimes subjected his sons to harsh physical discipline and verbal put-downs. Regarding the writing of Gary's memoir, Lindsay said, "I'm glad [Gary] did it. I hope it clears up a lot of the old lies and rumors." Unlike Gary, though, Lindsay stated that he preferred to remember "all the good things I did with my dad and forget the times that were rough". When the book was published, Dennis distanced himself by calling it "Gary's business" but did not publicly deny its claims. Bing's younger brother, singer and jazz bandleader Bob Crosby, recalled at the time of Gary's revelations that Bing was a "disciplinarian", as their mother and father had been. He added, "We were brought up that way." In an interview for the same article, Gary clarified that Bing "was like a lot of fathers of that time. He was not out to be vicious, to beat children for his kicks." Crosby's will established a blind trust in which none of the sons received an inheritance until they reached the age of 65. Lindsay Crosby died in 1989 at age 51, and Dennis Crosby died in 1991 at age 56, both by suicide from self-inflicted gunshot wounds. Gary Crosby died of lung cancer in 1995 at age 62, and Phillip Crosby died of a heart attack in 2004 at age 69. Widow Kathryn Crosby dabbled in local theater productions intermittently and appeared in television tributes to her late husband. Nathaniel Crosby, Crosby's younger son from his second marriage, is a former high-level golfer who won the U.S. Amateur in 1981 at age 19, becoming the youngest winner in the history of that event at the time. Harry Crosby is an investment banker who occasionally makes singing appearances. Denise Crosby, Dennis Crosby's daughter, is also an actress and is known for her role as Tasha Yar on Star Trek: The Next Generation and for the recurring role of the Romulan Sela after her withdrawal from the series as a regular cast member. She also appeared in the film adaptation of Stephen King's novel Pet Sematary. In 2006, Crosby's niece through his sister Mary Rose, Carolyn Schneider, published the laudatory book Me and Uncle Bing. There have been disputes between Crosby's two families beginning in the late 1990s. When Dixie died in 1952, her will provided that her share of the community property be distributed in trust to her sons. After Crosby's death in 1977, he left the residue of his estate to a marital trust for the benefit of his widow, Kathryn, and HLC Properties, Ltd., was formed for the purpose of managing his interests, including his right of publicity. In 1996, Dixie's trust sued HLC and Kathryn for declaratory relief as to the trust's entitlement to interest, dividends, royalties, and other income derived from the community property of Crosby and Dixie. In 1999, the parties settled for approximately $1.5 million. Relying on a retroactive amendment to the California Civil Code, Dixie's trust brought suit again, in 2010, alleging that Crosby's right of publicity was community property, and that Dixie's trust was entitled to a share of the revenue it produced. The trial court granted Dixie's trust's claim. The California Court of Appeal reversed, however, holding that the 1999 settlement barred the claim. In light of the court's ruling, it was unnecessary for the court to decide whether a right of publicity can be characterized as community property under California law. Illness and death Following his recovery from a life-threatening fungal infection of his right lung in January 1974, Crosby emerged from semi-retirement to start a new spate of albums and concerts. In March 1977, after videotaping a concert at the Ambassador Auditorium in Pasadena for CBS to commemorate his 50th anniversary in show business, and with Bob Hope looking on, Crosby fell off the stage into an orchestra pit, rupturing a disc in his back requiring a month in the hospital. His first performance after the accident was his last American concert, on August 16, 1977, the day Elvis Presley died, at the Concord Pavilion in Concord, California. When the electric power failed during his performance, he continued singing without amplification. In September, Crosby, his family and singer Rosemary Clooney began a concert tour of Britain that included two weeks at the London Palladium. While in the UK, Crosby recorded his final album, Seasons, and his final TV Christmas special with guest David Bowie on September 11 (which aired a little over a month after Crosby's death). His last concert was in the Brighton Centre on October 10, four days before his death, with British entertainer Gracie Fields in attendance. The following day he made his final appearance in a recording studio and sang eight songs at the BBC's Maida Vale Studios for a radio program, which also included an interview with Alan Dell. Accompanied by the Gordon Rose Orchestra, Crosby's last recorded performance was of the song "Once in a While". Later that afternoon, he met with Chris Harding to take photographs for the Seasons album jacket. On October 13, 1977, Crosby flew alone to Spain to play golf and hunt partridge. On October 14, at the La Moraleja Golf Course near Madrid, Crosby played 18 holes of golf. His partner was World Cup champion Manuel Piñero; their opponents were club president César de Zulueta and Valentín Barrios. According to Barrios, Crosby was in good spirits throughout the day, and was photographed several times during the round. At the ninth hole, construction workers building a house nearby recognized him, and when asked for a song, Crosby sang "Strangers in the Night". Crosby, who had a 13 handicap, won with his partner by one stroke. At about 6:30 pm, as Crosby and his party headed back to the clubhouse, Crosby said, "That was a great game of golf, fellas. Let's go have a Coca-Cola." These were his last words. About from the clubhouse entrance, Crosby collapsed and died instantly from a massive heart attack. At the clubhouse and later in the ambulance, house physician Dr. Laiseca tried to revive him, but was unsuccessful. At Reina Victoria Hospital he was administered the last rites of the Catholic Church and was pronounced dead. He was 74 years old. On October 18, 1977, following a private funeral Mass at St. Paul's Catholic Church in Westwood, Crosby was buried at Holy Cross Cemetery in Culver City, California. (His tombstone incorrectly identified his year of birth as 1904 instead of 1903.) A plaque was placed at the golf course in his memory. Legacy He is a member of the National Association of Broadcasters Hall of Fame in the radio division. The family created an official website on October 14, 2007, the 30th anniversary of Crosby's death. In his autobiography Don't Shoot, It's Only Me! (1990), Bob Hope wrote, "Dear old Bing, as we called him, the Economy-sized Sinatra. And what a voice. God I miss that voice. I can't even turn on the radio around Christmas time without crying anymore." Calypso musician Roaring Lion wrote a tribute song in 1939 titled "Bing Crosby", in which he wrote: "Bing has a way of singing with his very heart and soul / Which captivates the world / His millions of listeners never fail to rejoice / At his golden voice...." Bing Crosby Stadium in Front Royal, Virginia, was named after Crosby in honor of his fundraising and cash contributions for its construction from 1948 to 1950. In 2006, the former Metropolitan Theater of Performing Arts ('The Met') in Spokane, Washington, was renamed to The Bing Crosby Theater. Compositions Crosby wrote or co-wrote lyrics to 22 songs. His composition "At Your Command" was number 1 for three weeks on the U.S. pop singles chart beginning on August 8, 1931. "I Don't Stand a Ghost of a Chance With You" was his most successful composition, recorded by Duke Ellington, Frank Sinatra, Thelonious Monk, Billie Holiday, and Mildred Bailey, among others. Songs co-written by Crosby include: "That's Grandma" (1927), with Harry Barris and James Cavanaugh "From Monday On" (1928), with Harry Barris and recorded with the Paul Whiteman Orchestra featuring Bix Beiderbecke on cornet, number 14 on US pop singles charts "What Price Lyrics?"

The Brittonic, Brythonic, or British Celtic languages (; ; ) form one of the two branches of the Insular Celtic language family; the other is Goidelic. The name Brythonic was derived by Welsh Celticist John Rhys from the Welsh word , meaning Ancient Britons as opposed to an Anglo-Saxon or Gael. The Brittonic languages derive from the Common Brittonic language, spoken throughout Great Britain during the Iron Age and Roman period. In the 5th and 6th centuries emigrating Britons also took Brittonic speech to the continent, most significantly in Brittany and Britonia. During the next few centuries the language began to split into several dialects, eventually evolving into Welsh, Cornish, Breton, Cumbric, and probably Pictish. Welsh and Breton continue to be spoken as native languages, while a revival in Cornish has led to an increase in speakers of that language. Cumbric and Pictish are extinct, having been replaced by Goidelic and English speech. The Isle of Man and Orkney may also have originally spoken a Brittonic language, but this was later supplanted by Goidelic on the Isle of Man and Norse on Orkney. There is also a community of Brittonic language speakers in (the Welsh settlement in Patagonia). Name The names "Brittonic" and "Brythonic" are scholarly conventions referring to the Celtic languages of Britain and to the ancestral language they originated from, designated Common Brittonic, in contrast to the Goidelic languages originating in Ireland. Both were created in the 19th century to avoid the ambiguity of earlier terms such as "British" and "Cymric". "Brythonic" was coined in 1879 by the Celticist John Rhys from the Welsh word . "Brittonic", derived from "Briton" and also earlier spelled "Britonic" and "Britonnic", emerged later in the 19th century. It became more prominent through the 20th century, and was used in Kenneth H. Jackson's highly influential 1953 work on the topic, Language and History in Early Britain. Jackson noted that by that time "Brythonic" had become a dated term, and that "of late there has been an increasing tendency to use Brittonic instead." Today, "Brittonic" often replaces "Brythonic" in the literature. Rudolf Thurneysen used "Britannic" in his influential A Grammar of Old Irish, though this never became popular among subsequent scholars. Comparable historical terms include the Medieval Latin and and the Welsh . Some writers use "British" for the language and its descendants, though due to the risk of confusion, others avoid it or use it only in a restricted sense. Jackson, and later John T. Koch, use "British" only for the early phase of the Common Brittonic language. Before Jackson's work, "Brittonic" (and "Brythonic") were often used for all the P-Celtic languages, including not just the varieties in Britain but those Continental Celtic languages that similarly experienced the evolution of the Proto-Celtic language element to . However, subsequent writers have tended to follow Jackson's scheme, rendering this use obsolete. The name "Britain" itself comes from , via Old French and Middle English , possibly influenced by Old English , probably also from Latin Brittania, ultimately an adaptation of the native word for the island, *Pritanī. An early written reference to the British Isles may derive from the works of the Greek explorer Pytheas of Massalia; later Greek writers such as Diodorus of Sicily and Strabo who quote Pytheas' use of variants such as (), "The Britannic [land, island]", and νησοι βρεττανιαι (), "Britannic islands", with being a Celtic word that might mean "the painted ones" or "the tattooed folk", referring to body decoration (see below). Evidence Knowledge of the Brittonic languages comes from a variety of sources. The early language's information is obtained from coins, inscriptions, and comments by classical writers as well as place names and personal names recorded by them. For later languages, there is information from medieval writers and modern native speakers, together with place names. The names recorded in the Roman period are given in Rivet and Smith. Characteristics The Brittonic branch is also referred to as P-Celtic because linguistic reconstruction of the Brittonic reflex of the Proto-Indo-European phoneme *kʷ is p as opposed to Goidelic c. Such nomenclature usually implies acceptance of the P-Celtic and Q-Celtic hypothesis rather than the Insular Celtic hypothesis because the term includes certain Continental Celtic languages as well. (For a discussion, see Celtic languages.) Other major characteristics include: The retention of the Proto-Celtic sequences am and an, which mostly result from the Proto-Indo-European syllabic nasals. Celtic (written u in Latin texts and ou in Greek) became gw- in initial position, -w- internally, whereas in Gaelic it is f- in initial position and disappears internally: Proto-Celtic *windos "white, fair" became Welsh gwyn (masculine), gwen (feminine), Cornish gwynn, Breton gwenn. Contrast Irish fionn "fair". Proto-Celtic *wassos "servant, young man" became Welsh, Cornish and Breton gwas. Contrast Middle Irish foss. Initial s-: Initial s- followed by a vowel was changed to h-: Welsh hen "old", hir "long", hafal "similar" Breton hen "ancient", hir "long", hañval "similar" Cornish hen "ancient", hir "long", haval "similar" Contrast Irish sean "old", síor "long", samhail "similarity" Initial s- was lost before , and : *slemon became Welsh llyfn, Cornish leven and Breton levn "smooth". Contrast Irish sleamhain "smooth, slimy" *smeru became Welsh mêr, Cornish mer, and Breton mel "marrow". Contrast Irish sméar The initial clusters sp-, sr-, sw- became f-, fr-, chw-: *sɸera became Welsh ffêr "ankle", Cornish fer "shank, lower leg" and Breton fer "ankle". Contrast Old Irish seir "heel, ankle" *srogna "nostril" became Welsh ffroen, Cornish frig and Breton froen. Contrast Irish srón *swīs "you" (plural) became Welsh chwi, Cornish hwy and Breton c'hwi.

Welsh and Breton have been spoken continuously since they formed. For all practical purposes Cornish died out during the 18th or 19th centuries, but a revival movement has more recently created small numbers of new speakers. Also notable are the extinct language Cumbric, and possibly the extinct Pictish. One view, advanced in the 1950s and based on apparently unintelligible ogham inscriptions, was that the Picts may have also used a non-Indo-European language. This view, while attracting broad popular appeal, has virtually no following in contemporary linguistic scholarship. History and origins The modern Brittonic languages are generally considered to all derive from a common ancestral language termed Brittonic, British, Common Brittonic, Old Brittonic or Proto-Brittonic, which is thought to have developed from Proto-Celtic or early Insular Celtic by the 6th century BC. A major archaeogenetics study uncovered a migration into southern Britain in the Bronze Age, during the 500-year period 1,300–800 BC. The newcomers were genetically most similar to ancient individuals from Gaul. During 1,000–875 BC, their genetic marker swiftly spread through southern Britain, but not northern Britain. The authors describe this as a "plausible vector for the spread of early Celtic languages into Britain". There was much less inward migration during the Iron Age, so it is likely that Celtic reached Britain before then. Barry Cunliffe suggests that a branch of Celtic was already being spoken in Britain, and that the Bronze Age migration introduced the Brittonic branch. Brittonic languages were probably spoken before the Roman invasion throughout most of Great Britain, though the Isle of Man later had a Goidelic language, Manx. During the period of the Roman occupation of what is now England and Wales (AD 43 to c. 410), Common Brittonic borrowed a large stock of Latin words, both for concepts unfamiliar in the pre-urban society of Celtic Britain such as urbanization and new tactics of warfare as well as for rather more mundane words which displaced native terms (most notably, the word for "fish" in all the Brittonic languages derives from the Latin piscis rather than the native *ēskos - which may survive, however, in the Welsh name of the River Usk, ). Approximately 800 of these Latin loan-words have survived in the three modern Brittonic languages. Pictish may have resisted Latin influence to a greater extent than the other Brittonic languages. It is probable that at the start of the Post-Roman period Common Brittonic was differentiated into at least two major dialect groups – Southwestern and Western (also we may posit additional dialects, such as Eastern Brittonic, spoken in what is now the East of England, which have left little or no evidence). Between the end of the Roman occupation and the mid 6th century the two dialects began to diverge into recognizably separate varieties, the Western into Cumbric and Welsh and the Southwestern into Cornish and its closely related sister language Breton, which was carried to continental Armorica. Jackson showed that a few of the dialect distinctions between West and Southwest Brittonic go back a long way. New divergencies began around AD 500 but other changes that were shared occurred in the 6th century. Other common changes occurred in the 7th century onward and are possibly due to inherent tendencies. Thus the concept of a Common Brittonic language ends by AD 600. Substantial numbers of Britons certainly remained in the expanding area controlled by Anglo-Saxons, but over the fifth and sixth centuries they mostly adopted the English language. Decline The Brittonic languages spoken in what is now Scotland, the Isle of Man and what is now England began to be displaced in the 5th century through the settlement of Irish-speaking Gaels and Germanic peoples. Henry of Huntingdon wrote that Pictish was "no longer spoken" in c.1129. The displacement of the languages of Brittonic descent was probably complete in all of Britain except Cornwall and Wales and the English counties bordering these areas such as Devon by the 11th century. Western Herefordshire continued to speak Welsh until the late nineteenth century, and isolated pockets of Shropshire speak Welsh today. Sound changes The regular consonantal sound changes from Proto-Celtic to Welsh, Cornish, and Breton are summarised in the following table. Where the graphemes have a different value from the corresponding IPA symbols, the IPA equivalent is indicated between slashes. V represents a vowel; C represents a consonant. Remnants in England, Scotland and Ireland Place names and river names The principal legacy left behind in those territories from which the Brittonic languages were displaced is that of toponyms (place names) and hydronyms (river names). There are many Brittonic place names in lowland Scotland and in the parts of England where it is agreed that substantial Brittonic speakers remained (Brittonic names, apart from those of the former Romano-British towns, are scarce over most of England). Names derived (sometimes indirectly) from Brittonic include London, Penicuik, Perth, Aberdeen, York, Dorchester, Dover and Colchester. Brittonic elements found in England include bre- and bal- for hills, while some such as combe or coomb(e) for a small deep valley and tor for a hill are examples of Brittonic words that were borrowed into English. Others reflect the presence of Britons such as Dumbarton – from the Scottish Gaelic Dùn Breatainn meaning "Fort of the Britons", or Walton meaning a tun or settlement where the Wealh "Britons" still lived. The number of Celtic river names in England generally increases from east to west, a map showing these being given by Jackson. These names include ones such as Avon, Chew, Frome, Axe, Brue and Exe, but also river names containing the elements "der-/dar-/dur-" and "-went" e.g. "Derwent, Darwen, Deer, Adur, Dour, Darent, Went". These names exhibit multiple different Celtic roots. One is *dubri- "water" [Bret. "dour", C. "dowr", W. "dŵr"], also found in the place-name "Dover" (attested in the Roman period as "Dubrīs"); this is the source of rivers named "Dour". Another is *deru̯o- "oak" or "true" [Bret. "derv", C. "derow", W. "derw"], coupled with 2 agent suffixes, *-ent- and *-iū; this is the origin of "Derwent", " Darent" and "Darwen" (attested in the Roman period as "Deru̯entiō"). The final root to be examined is "went". In Roman Britain, there were three tribal capitals named "U̯entā" (modern Winchester, Caerwent and Caistor St Edmunds), whose meaning was 'place, town'. Brittonicisms in English Some, including J. R. R. Tolkien, have argued that Celtic has acted as a substrate to English for both the lexicon and syntax. It is generally accepted that Brittonic effects on English are lexically few aside from toponyms, consisting of a small number of domestic and geographical words, which may include bin, brock, carr, comb, crag and tor. Another legacy may be the sheep-counting system Yan Tan Tethera in the north, in the traditionally Celtic areas of England such as Cumbria. Several Cornish mining words are still in use in English language mining terminology, such as costean, gunnies, and vug. Those who argue against the theory of a more significant Brittonic influence than is widely accepted point out that many toponyms have no semantic continuation from the Brittonic language. A notable example is Avon which comes from the Celtic term for river abona or the Welsh term for river, afon, but was used by the English as a personal name. Likewise the River Ouse, Yorkshire contains the word usa which merely means 'water' and the name of the river Trent simply comes from the Welsh word for a trespasser (an over-flowing river). It has been argued that the use of periphrastic constructions (using auxiliary verbs such as do and be in the continuous/progressive) in the English verb, which is more widespread than in the other Germanic languages, is traceable to Brittonic influence. Others, however, find this unlikely due to the fact that many of these forms are only attested in the later Middle English period; these scholars claim a native English development rather than Celtic influence. Ian G. Roberts postulates Northern Germanic influence, despite such constructions not existing in Norse. Literary Welsh has the simple present Caraf = I love and the present stative (al. continuous/progressive) Yr wyf yn caru = I am loving, where the Brittonic syntax is partly mirrored in English (Note that I am loving comes from older I am a-loving, from still older ich am on luvende "I am in the process of loving"). In the Germanic sister languages of English there is only one form, for example ich liebe in German, though in colloquial usage in some German dialects, a progressive aspect form has evolved which is formally similar to those found in Celtic languages, and somewhat less similar to the Modern English form, e.g. "I am working" is ich bin am Arbeiten, literally: "I am on the working". The same structure is also found in modern Dutch (ik ben aan het werk), alongside other structures (e.g. ik zit te werken, lit. "I sit to working"). These parallel developments suggest that the English progressive is not necessarily due to Celtic influence; moreover, the native English development of the structure can be traced over 1000 years and more of English literature. Some researchers (Filppula et al., 2001) argue that other elements of English syntax reflect Brittonic influences. For instance, in English tag questions, the form of the tag depends on the verb form in the main statement (aren't I?, isn't he?, won't we? etc.). The German nicht wahr? and the French n'est-ce pas?, by contrast, are fixed forms which can be used with almost any main statement. It has been claimed that the English system has been borrowed from Brittonic, since Welsh tag questions vary in almost exactly the same way. Brittonic effect on the Goidelic languages Far more notable, but less well known, are Brittonic influences on Scottish Gaelic, though Scottish and Irish Gaelic, with their wider range of preposition-based periphastic constructions, suggest that such constructions descend from their common Celtic heritage. Scottish Gaelic contains several P-Celtic loanwords, but as there is a far greater overlap in terms of Celtic vocabulary, than with English, it is not always possible to disentangle P- and Q-Celtic words. However some common words such as monadh = Welsh mynydd, Cumbric *monidh are particularly evident. Often the Brittonic influence on Scots Gaelic is indicated by considering Irish language usage, which is not likely to have been influenced so much by Brittonic. In particular, the word srath (anglicised as "Strath") is a native Goidelic word, but its usage appears to have been modified by the Brittonic cognate ystrad whose meaning is slightly different. The effect on Irish has been the loan from British of many Latin-derived words. This has been associated with the Christianisation of Ireland from Britain. References Notes Sources Aleini M (1996).

The Branco River (; Engl: White River) is the principal affluent of the Rio Negro from the north. Basin The river drains the Guayanan Highlands moist forests ecoregion. It is enriched by many streams from the Tepui highlands which separate Venezuela and Guyana from Brazil. Its two upper main tributaries are the Uraricoera and the Takutu. The latter almost links its sources with those of the Essequibo; during floods headwaters of the Branco and those of the Essequibo are connected, allowing a level of exchange in the aquatic fauna (such as fish) between the two systems. The Branco flows nearly south, and finds its way into the Negro through several channels and a chain of lagoons similar to those of the latter river. It is long, up to its Uraricoera confluence. It has numerous islands, and, above its mouth, it is broken by a bad series of rapids. Water chemistry As suggested by its name, the Branco (literally "white" in Portuguese) has whitish water that may appear almost milky due to the inorganic sediments it carries. It is traditionally considered a whitewater river, although the major seasonal fluctuations in its physico-chemical characteristics makes a classification difficult and some consider it clearwater. Especially the river's upper parts at the headwaters are clear and flow through rocky country, leading to the suggestion that sediments mainly originate from the lower parts. Furthermore, its chemistry and color may contradict each other compared to the traditional Amazonian river classifications. The Branco River has pH 6–7 and low levels of dissolved organic carbon. Alfred Russel Wallace mentioned the coloration in "On the Rio Negro", a paper read at the 13 June 1853 meeting of the Royal Geographical Society, in which he said: "[The Rio Branco] is white to a remarkable degree, its waters being actually milky in appearance". Alexander von Humboldt attributed the color to the presence of silicates in the water, principally mica and talc. There is a visible contrast with the waters of the Rio Negro at the confluence of the two rivers. The Rio Negro is a blackwater river with dark tea-colored acidic water (pH 3.5–4.5) that contains high levels of dissolved organic carbon. River capture Until approximately 20,000 years ago the headwaters of the Branco River flowed not into the Amazon, but via the Takutu Graben in the Rupununi area of Guyana towards the Caribbean. Currently in the rainy season much of the Rupununi area floods, with water draining both to the Amazon (via the Branco River) and the Essequibo River.

Barcelonnette (; , also ; obsolete ) is a commune of France and a subprefecture in the department of Alpes-de-Haute-Provence, in the Provence-Alpes-Côte d'Azur region. It is located in the southern French Alps, at the crossroads between Provence, Piedmont and the Dauphiné, and is the largest town in the Ubaye Valley. The town's inhabitants are known as Barcelonnettes. Toponymy Barcelonnette was founded and named in 1231, by Ramon Berenguer IV, Count of Provence. While the town's name is generally seen as a diminutive form of Barcelona in Catalonia, Albert Dauzat and Charles Rostaing point out an earlier attestation of the name Barcilona in Barcelonnette in around 1200, and suggest that it is derived instead from two earlier stems signifying a mountain, *bar and *cin (the latter of which is also seen in the name of Mont Cenis). In the Vivaro-Alpine dialect of Occitan, the town is known as Barcilona de Provença or more rarely Barciloneta according to the classical norm; under the Mistralian norm it is called Barcilouna de Prouvença or Barcilouneto. In Valéian (the dialect of Occitan spoken in the Ubaye Valley), it is called Barcilouna de Prouvença or Barcilounéta. Barcino Nova is the town's Latin name meaning "new Barcelona"; Barcino was the Roman name for Barcelona in Catalonia from its foundation by Emperor Augustus in 10 BC, and it was only changed to Barcelona in the Middle Ages. The inhabitants of the town are called Barcelonnettes, or Vilandroises in Valéian. History Origins The Barcelonnette region was populated by Ligures from the 1st millennium BC onwards, and the arrival of the Celts several centuries later led to the formation of a mixed Celto-Ligurian people, the Vesubians. Polybius described the Vesubians as belligerent but nonetheless civilised and mercantile, and Julius Caesar praised their bravery. The work History of the Gauls also places the Vesubians in the Ubaye Valley. Following the Roman conquest of Provence, Barcelonnette was included in a small province with modern Embrun as its capital and governed by Albanus Bassalus. This was integrated soon afterwards into Gallia Narbonensis. In 36 AD, Emperor Nero transferred Barcelonnette to the province of the Cottian Alps. The town was known as Rigomagensium under the Roman Empire and was the capital of a civitas (a provincial subdivision), though no Roman money has yet been found in the canton of Barcelonnette. Medieval town The town of Barcelonnette was founded in 1231 by Ramon Berenguer IV, Count of Provence. According to Charles Rostaing, this act of formal "foundation", according certain privileges to the town, was a means of regenerating the destroyed town of Barcilona. The town was afforded a consulat (giving it the power to administer and defend itself) in 1240. Control of the area in the Middle Ages swung between the Counts of Savoy and of Provence. In 1388, after Count Louis II of Provence had left to conquer Naples, the Count of Savoy Amadeus VIII took control of Barcelonnette; however, it returned to Provençal control in 1390, with the d'Audiffret family as its lords. On the death of Louis II in 1417 it reverted to Savoy, and, although Count René again retook the area for Provence in 1471, it had returned to Savoyard dominance by the start of the 16th century, by which point the County of Provence had become united with the Kingdom of France due to the death of Count Charles V in 1481. Ancien Régime During Charles V's invasion of Provence in 1536, Francis I of France sent the Count of Fürstenberg's 6000 Landsknechte to ravage the area in a scorched earth policy. Barcelonnette and the Ubaye Valley remained under French sovereignty until the second Treaty of Cateau-Cambrésis on 3 April 1559. In 1588 the troops of François, Duke of Lesdiguières entered the town and set fire to the church and convent during their campaign against the Duke of Savoy. In 1600, after the Treaty of Vervins, conflict returned between Henry IV of France and Savoy, and Lesdiguières retook Barcelonnette until the conclusion of the Treaty of Lyon on 17 January the following year. In 1628, during the War of the Mantuan Succession, Barcelonnette and the other towns of the Ubaye Valley were pillaged and burned by Jacques du Blé d'Uxelles and his troops, as they passed through towards Italy to the Duke of Mantua's aid. The town was retaken by the Duke of Savoy in 1630; and in 1691 it was captured by the troops of the Marquis de Vins during the War of the League of Augsburg. Between 1614 and 1713, Barcelonnette was the seat of one of the four prefectures under the jurisdiction of the Senate of Nice. At this time, the community of Barcelonnette successfully purchased the seigneurie of the town as it was put to auction by the Duke of Savoy; it thereby gained its own justicial powers. In 1646, a college was founded in Barcelonnette. A "significant" part of the town's inhabitants had, by the 16th century, converted to Protestantism, and were repressed during the French Wars of Religion. The viguerie of Barcelonnette (also comprising Saint-Martin and Entraunes) was reattached to France in 1713 as part of a territorial exchange with the Duchy of Savoy during the Treaties of Utrecht. The town remained the site of a viguerie until the French Revolution. A decree of the council of state on 25 December 1714 reunited Barcelonnete with the general government of Provence. Revolution Barcelonnette was one of few settlements in Haute-Provence to acquire a Masonic Lodge before the Revolution, in fact having two: the lodge of Saint-Jean-d'Écosse des amis réunis, affiliated with the Saint-Jean-d'Écosse lodge in Marseille; the lodge of Saint-Jean, affiliated with the Saint-Jean-de-Jérusalem d'Avignon lodge founded in 1749. In March 1789, riots took place as a result of a crisis in wheat production. In July, the Great Fear of aristocratic reprisal against the ongoing French Revolution struck France, arriving in the Barcelonnette area on 31 July 1789 (when the news of the storming of the Bastille first reached the town) before spreading towards Digne. This agitation continued in the Ubaye Valley; a new revolt broke out on 14 June, and famine was declared in April 1792. The patriotic society of the commune was one of the first 21 created in Alpes-de-Haute-Provence, in spring 1792, by the envoys of the departmental administration. Around a third of the male population attended at the club. Another episode of political violence occurred in August 1792. Barcelonnette was the seat of the District of Barcelonnette from 1790 to 1800. Modern history In December 1851, the town was home to a movement of republican resistance towards Napoleon III's coup. Though only a minority of the population, the movement rebelled on Sunday 7 December, the day after the news of the coup arrived. Town officials and gendarmes were disarmed and placed in the maison d'arrêt. A committee of public health was created on 8 December; on 9 December the inhabitants of Jausiers and its surroundings formed a colony under the direction of general councillor Brès, and Mayor Signoret of Saint-Paul-sur-Ubaye. This was stopped, however, on 10 December before it could reach Barcelonnette, as the priest of the subprefecture had intervened. On 11 December, several officials escaped and found refuge in L'Argentière in Piedmont. The arrival of troops on 16 December put a final end to the republican resistance without bloodshed, and 57 insurgents were tried; 38 were condemned to deportation (though several were pardoned in April). Between 1850 and 1950, Barcelonnette was the source of a wave of emigration to Mexico. Among these emigrants was Jean Baptiste Ebrard, founder of the Liverpool department store chain in Mexico; Marcelo Ebrard, the head of government of Mexico City from 2006 to 2012, is one of his descendents. On the edges of Barcelonnette and Jausiers there are several houses and villas of colonial style (known as maisons mexicaines), constructed by emigrants to Mexico who returned to France between 1870 and 1930. A plaque in the town commemorates the deaths of ten Mexican citizens who returned to Barcelonnette to fight in the First World War. During the Second World War, 26 Jews were arrested in Barcelonnette before being deported. The 89th compagnie de travailleurs étrangers (Company of Foreign Workers), consisting of foreigners judged as undesirable by the Third Republic and the Vichy regime and committed to forced labour, was established in Barcelonnette. The 11th Battalion of Chasseurs alpins was garrisoned at Barcelonnette between 1948 and 1990. Geography Barcelonnette is situated in the wide and fertile Ubaye Valley, of which it is the largest town. It lies at an elevation of 1132 m (3717 ft) on the right bank of the Ubaye River, and is surrounded by mountains which reach peaks of over 3000 m; the tallest of these is the Needle of Chambeyron at 3412 m. Barcelonnette is situated 210 km from Turin, 91 km from Nice and 68 km from Gap. Biodiversity As a result of its relief and geographic situation, the Ubaye Valley has an "abundance of plant and animal species". The fauna is largely constituted of golden eagles, marmots, ibex and vultures, and the flora includes a large proportion of larches, génépis and white asphodels. Climate The Ubaye Valley has an alpine climate and winters are harsh as a result of the altitude, but there are only light winds as a result of the relief. There are on average almost 300 days of sun and 700 mm of rain per year. Hazards None of the 200 communes of the department is entirely free of seismic risk; the canton of Barcelonnette is placed in zone 1b (low risk) by the determinist classification of 1991 based on seismic history, and zone 4 (average risk) according to the probabilistic EC8 classification of 2011. The commune is also vulnerable to avalanches, forest fires, floods, and landslides. Barcelonnette is also exposed to the possibility of a technological hazard in that road transport of dangerous materials is allowed to pass through on the RD900. The town has been subject to several orders of natural disaster: floods and mudslides in 1994 and 2008, and landslides in 1996 and 1999. The strongest recorded earthquakes in the region occurred on 5 April 1959, with its epicentre at Saint-Paul-sur-Ubaye and a recorded intensity of 6.5 at Barcelonnette, and on 17 February 1947, with its epicentre at Prazzo over the Italian border. Architecture The town hall was constructed in the 1930s after the destruction of the Saint Maurice chapel in July 1934. Its pediment was originally from the old Dominican convent and was identified in 1988. No houses in the town date from before the 17th century, the town having been rebuilt after the fire of 1628. The old hospital in the town dates from 1717. The old gendarmerie on Place Manuel was originally constructed to house the subprefecture in 1825 in a neoclassical style, and its façade occupies one entire side of the square. Place Manuel was named after the Restoration politician Jacques-Antoine Manuel; the fountain in the centre of the square contains his image sculpted by David d'Angers. The parish church was originally built in the Middle Ages, but was destroyed in the fire of 1628. It was quickly reconstructed between 1634 and 1638, and further between 1643 and 1644. This was later demolished in 1926–27 to allow the construction of the current church, though this still contains the steeple from the 17th-century reconstruction. The Cardinalis tower was constructed in the 14th century as a bell tower for the Dominican convent, which was founded on the bequest of Hugh of Saint-Cher. It was damaged in the wars of the 17th century and was rebuilt, though parts still exist from the original construction. It is classed as a monument historique of France. The subprefecture has been situated since 1978 in a maison mexicaine, the Villa l'Ubayette, constructed between 1901 and 1903. Population In 1471, the community of Barcelonnette (including several surrounding parishes) comprised 421 fires (households). In 1765, it had 6,674 inhabitants, but emigration, particularly to Mexico, slowed the town's growth in the period before the Second World War. According to the census of 2017, Barcelonnette has a population of 2,598 (municipal population) across a total area of 16.42 km2. The town is characterised by low population density. Between 1990 and 1999 the town's annual mean population growth was -0.6%, though between 1999 and 2007 this increased to an average of -0.2%. Economy The city is mainly a tourist and resort centre, serving many ski lodges. The Pra-Loup resort is 7 km from Barcelonnette; Le Sauze is 5 km away. It and the Ubaye Valley are served by the Barcelonnette – Saint-Pons Airfield. Notably, Barcelonnette is the only subprefecture of France not served by rail transport; the Ubaye line which would have linked Chorges to Barcelonnette was never completed as a result of the First World War and the construction of the Serre-Ponçon Dam between 1955 and 1961. Education An école normale (an institute for training primary school teachers) was founded in Barcelonnette in 1833, and remained there until 1888 when it was transferred to Digne. The lycée André-Honnorat de Barcelonnette, originally the collège Saint-Maurice and renamed after the politician André Honnorat in 1919, is located in the town; Pierre-Gilles de Gennes and Carole Merle both studied there. Currently, three schools exist in Barcelonnette: a public nursery school, a public elementary school, and a private school (under a contract by which the teachers are paid by the national education system). In 2010 the lycée André-Honnorat opened a boarding school aimed at gifted students of poorer social backgrounds, in order to give them better conditions in which to study. It is located in the Quartier Craplet, formerly the garrison of the 11th Battalion of Chasseurs Alpins and then the French Army's Centre d'instruction et d'entraînement au combat en montagne (CIECM). International links Barcelonnette is twinned with: Valle de Bravo, Mexico It is also the site of a Mexican honorary consulate. Notable residents Pierre-Gilles de Gennes (1932–2007), physicist and winner of the Nobel Prize in Physics in 1991 Jacques-Antoine Manuel (1775–1827), lawyer, politician and orator Paul Reynaud (1878–1966), liberal politician and lawyer Daniel Spagnou (born 1940), UMP politician Bruno Dary (born 1952), general and military governor of Paris References External links Tourism website Communes of Alpes-de-Haute-Provence Subprefectures in France

In computer science, a binary tree is a tree data structure in which each node has at most two children, which are referred to as the and the . A recursive definition using just set theory notions is that a (non-empty) binary tree is a tuple (L, S, R), where L and R are binary trees or the empty set and S is a singleton set containing the root. Some authors allow the binary tree to be the empty set as well. From a graph theory perspective, binary (and K-ary) trees as defined here are arborescences. A binary tree may thus be also called a bifurcating arborescence—a term which appears in some very old programming books, before the modern computer science terminology prevailed. It is also possible to interpret a binary tree as an undirected, rather than a directed graph, in which case a binary tree is an ordered, rooted tree. Some authors use rooted binary tree instead of binary tree to emphasize the fact that the tree is rooted, but as defined above, a binary tree is always rooted. A binary tree is a special case of an ordered K-ary tree, where K is 2. In mathematics, what is termed binary tree can vary significantly from author to author. Some use the definition commonly used in computer science, but others define it as every non-leaf having exactly two children and don't necessarily order (as left/right) the children either. In computing, binary trees are used in two very different ways: First, as a means of accessing nodes based on some value or label associated with each node. Binary trees labelled this way are used to implement binary search trees and binary heaps, and are used for efficient searching and sorting. The designation of non-root nodes as left or right child even when there is only one child present matters in some of these applications, in particular, it is significant in binary search trees. However, the arrangement of particular nodes into the tree is not part of the conceptual information. For example, in a normal binary search tree the placement of nodes depends almost entirely on the order in which they were added, and can be re-arranged (for example by balancing) without changing the meaning. Second, as a representation of data with a relevant bifurcating structure. In such cases, the particular arrangement of nodes under and/or to the left or right of other nodes is part of the information (that is, changing it would change the meaning). Common examples occur with Huffman coding and cladograms. The everyday division of documents into chapters, sections, paragraphs, and so on is an analogous example with n-ary rather than binary trees. Definitions Recursive definition To actually define a binary tree in general, we must allow for the possibility that only one of the children may be empty. An artifact, which in some textbooks is called an extended binary tree is needed for that purpose. An extended binary tree is thus recursively defined as: the empty set is an extended binary tree if T1 and T2 are extended binary trees, then denote by T1 • T2 the extended binary tree obtained by by adding edges when these sub-trees are non-empty. Another way of imagining this construction (and understanding the terminology) is to consider instead of the empty set a different type of node—for instance square nodes if the regular ones are circles. Using graph theory concepts A binary tree is a rooted tree that is also an ordered tree (a.k.a. plane tree) in which every node has at most two children. A rooted tree naturally imparts a notion of levels (distance from the root), thus for every node a notion of children may be defined as the nodes connected to it a level below. Ordering of these children (e.g., by drawing them on a plane) makes it possible to distinguish a left child from a right child. But this still doesn't distinguish between a node with left but not a right child from a one with right but no left child. The necessary distinction can be made by first partitioning the edges, i.e., defining the binary tree as triplet (V, E1, E2), where (V, E1 ∪ E2) is a rooted tree (equivalently arborescence) and E1 ∩ E2 is empty, and also requiring that for all j ∈ { 1, 2 } every node has at most one Ej child. A more informal way of making the distinction is to say, quoting the Encyclopedia of Mathematics, that "every node has a left child, a right child, neither, or both" and to specify that these "are all different" binary trees. Types of binary trees Tree terminology is not well-standardized and so varies in the literature. A binary tree has a root node and every node has at most two children. A binary tree (sometimes referred to as a proper or plane binary tree) is a tree in which every node has either 0 or 2 children. Another way of defining a full binary tree is a recursive definition. A full binary tree is either: A single vertex. A tree whose root node has two subtrees, both of which are full binary trees. In a binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 and 2h nodes at the last level h. An alternative definition is a perfect tree whose rightmost leaves (perhaps all) have been removed. Some authors use the term complete to refer instead to a perfect binary tree as defined below, in which case they call this type of tree (with a possibly not filled last level) an almost complete binary tree or nearly complete binary tree. A complete binary tree can be efficiently represented using an array. A binary tree is a binary tree in which all interior nodes have two children and all leaves have the same depth or same level. An example of a perfect binary tree is the (non-incestuous) ancestry chart of a person to a given depth, as each person has exactly two biological parents (one mother and one father). Provided the ancestry chart always displays the mother and the father on the same side for a given node, their sex can be seen as an analogy of left and right children, children being understood here as an algorithmic term. A perfect tree is therefore always complete but a complete tree is not necessarily perfect. In the infinite complete binary tree, every node has two children (and so the set of levels is countably infinite). The set of all nodes is countably infinite, but the set of all infinite paths from the root is uncountable, having the cardinality of the continuum. That's because these paths correspond by an order-preserving bijection to the points of the Cantor set, or (using the example of a Stern–Brocot tree) to the set of positive irrational numbers. A balanced binary tree is a binary tree structure in which the left and right subtrees of every node differ in height by no more than 1. One may also consider binary trees where no leaf is much farther away from the root than any other leaf. (Different balancing schemes allow different definitions of "much farther".<ref>Paul E. Black (ed.), entry for data structure in Dictionary of Algorithms and Data Structures. U.S. National Institute of Standards and Technology. 15 December 2004. Online version Accessed 2010-12-19.</ref>) A degenerate (or pathological) tree is where each parent node has only one associated child node. This means that the tree will behave like a linked list data structure. Properties of binary trees The number of nodes in a full binary tree is at least and at most , where is the height of the tree. A tree consisting of only a root node has a height of 0. The number of leaf nodes in a perfect binary tree, is because the number of non-leaf (a.k.a. internal) nodes . This means that a full binary tree with leaves has nodes. In a balanced full binary tree, (see ceiling function). In a perfect full binary tree, thus . The number of null links (i.e., absent children of the nodes) in a binary tree of n nodes is (n+1). The number of internal nodes in a complete binary tree of n nodes is . For any non-empty binary tree with n0 leaf nodes and n2 nodes of degree 2, n0 = n2 + 1. Combinatorics In combinatorics one considers the problem of counting the number of full binary trees of a given size. Here the trees have no values attached to their nodes (this would just multiply the number of possible trees by an easily determined factor), and trees are distinguished only by their structure; however, the left and right child of any node are distinguished (if they are different trees, then interchanging them will produce a tree distinct from the original one). The size of the tree is taken to be the number n of internal nodes (those with two children); the other nodes are leaf nodes and there are of them. The number of such binary trees of size n is equal to the number of ways of fully parenthesizing a string of symbols (representing leaves) separated by n binary operators (representing internal nodes), to determine the argument subexpressions of each operator. For instance for one has to parenthesize a string like , which is possible in five ways: The correspondence to binary trees should be obvious, and the addition of redundant parentheses (around an already parenthesized expression or around the full expression) is disallowed (or at least not counted as producing a new possibility). There is a unique binary tree of size 0 (consisting of a single leaf), and any other binary tree is characterized by the pair of its left and right children; if these have sizes i and j respectively, the full tree has size . Therefore, the number of binary trees of size n has the following recursive description , and for any positive integer n. It follows that is the Catalan number of index n. The above parenthesized strings should not be confused with the set of words of length 2n in the Dyck language, which consist only of parentheses in such a way that they are properly balanced. The number of such strings satisfies the same recursive description (each Dyck word of length 2n is determined by the Dyck subword enclosed by the initial '(' and its matching ')' together with the Dyck subword remaining after that closing parenthesis, whose lengths 2i and 2j satisfy ); this number is therefore also the Catalan number . So there are also five Dyck words of length 6: These Dyck words do not correspond to binary trees in the same way. Instead, they are related by the following recursively defined bijection: the Dyck word equal to the empty string corresponds to the binary tree of size 0 with only one leaf. Any other Dyck word can be written as (), where , are themselves (possibly empty) Dyck words and where the two written parentheses are matched. The bijection is then defined by letting the words and correspond to the binary trees that are the left and right children of the root. A bijective correspondence can also be defined as follows: enclose the Dyck word in an extra pair of parentheses, so that the result can be interpreted as a Lisp list expression (with the empty list () as only occurring atom); then the dotted-pair expression for that proper list is a fully parenthesized expression (with NIL as symbol and '.' as operator) describing the corresponding binary tree (which is, in fact, the internal representation of the proper list). The ability to represent binary trees as strings of symbols and parentheses implies that binary trees can represent the elements of a free magma on a singleton set. Methods for storing binary trees Binary trees can be constructed from programming language primitives in several ways. Nodes and references In a language with records and references, binary trees are typically constructed by having a tree node structure which contains some data and references to its left child and its right child. Sometimes it also contains a reference to its unique parent. If a node has fewer than two children, some of the child pointers may be set to a special null value, or to a special sentinel node. This method of storing binary trees wastes a fair bit of memory, as the pointers will be null (or point to the sentinel) more than half the time; a more conservative representation alternative is threaded binary tree. In languages with tagged unions such as ML, a tree node is often a tagged union of two types of nodes, one of which is a 3-tuple of data, left child, and right child, and the other of which is a "leaf" node, which contains no data and functions much like the null value in a language with pointers. For example, the following line of code in OCaml (an ML dialect) defines a binary tree that stores a character in each node. type chr_tree = Empty | Node of char * chr_tree * chr_tree Arrays Binary trees can also be stored in breadth-first order as an implicit data structure in arrays, and if the tree is a complete binary tree, this method wastes no space. In this compact arrangement, if a node has an index i, its children are found at indices (for the left child) and (for the right), while its parent (if any) is found at index (assuming the root has index zero). Alternatively, with a 1-indexed array, the implementation is simplified with children found at and , and parent found at . This method benefits from more compact storage and better locality of reference, particularly during a preorder traversal. However, it is expensive to grow and wastes space proportional to 2h - n for a tree of depth h with n nodes. This method of storage is often used for binary heaps. Encodings Succinct encodings A succinct data structure is one which occupies close to minimum possible space, as established by information theoretical lower bounds. The number of different binary trees on nodes is , the th Catalan number (assuming we view trees with identical structure as identical). For large , this is about ; thus we need at least about bits to encode it. A succinct binary tree therefore would occupy bits. One simple representation which meets this bound is to visit the nodes of the tree in preorder, outputting "1" for an internal node and "0" for a leaf. If the tree contains data, we can simply simultaneously store it in a consecutive array in preorder. This function accomplishes this: function EncodeSuccinct(node n, bitstring structure, array data) { if n = nil then append 0 to structure; else append 1 to structure; append n.data to data; EncodeSuccinct(n.left, structure, data); EncodeSuccinct(n.right, structure, data); } The string structure has only bits in the end, where is the number of (internal) nodes; we don't even have to store its length. To show that no information is lost, we can convert the output back to the original tree like this: function DecodeSuccinct(bitstring structure, array data) { remove first bit of structure and put it in b if b = 1 then create a new node n remove first element of data and put it in n.data n.left = DecodeSuccinct(structure, data) n.right = DecodeSuccinct(structure, data) return n else return nil } More sophisticated succinct representations allow not only compact storage of trees but even useful operations on those trees directly while they're still in their succinct form. Encoding general trees as binary trees There is a one-to-one mapping between general ordered trees and binary trees, which in particular is used by Lisp to represent general ordered trees as binary trees. To convert a general ordered tree to a binary tree, we only need to represent the general tree in left-child right-sibling way. The result of this representation will automatically be a binary tree if viewed from a different perspective. Each node N in the ordered tree corresponds to a node N' in the binary tree; the left child of N' is the node corresponding to the first child of N, and the right child of N' is the node corresponding to N 's next sibling --- that is, the next node in order among the children of the parent of N. This binary tree representation of a general order tree is sometimes also referred to as a left-child right-sibling binary tree (also known as LCRS tree, doubly chained tree, filial-heir chain). One way of thinking about this is that each node's children are in a linked list, chained together with their right fields, and the node only has a pointer to the beginning or head of this list, through its left field. For example, in the tree on the left, A has the 6 children {B,C,D,E,F,G}. It can be converted into the binary tree on the right. The binary tree can be thought of as the original tree tilted sideways, with the black left edges representing first child and the blue right edges representing next sibling. The leaves of the tree on the left would be written in Lisp as: (((N O) I J) C D ((P) (Q)) F (M)) which would be implemented in memory as the binary tree on the right, without any letters on those nodes that have a left child. Common operations There are a variety of different operations that can be performed on binary trees. Some are mutator operations, while others simply return useful information about the tree. Insertion Nodes can be inserted into binary trees in between two other nodes or added after a leaf node. In binary trees, a node that is inserted is specified as to whose child it will be. Leaf nodes To add a new node after leaf node A, A assigns the new node as one of its children and the new node assigns node A as its parent. Internal nodes Insertion on internal nodes is slightly more complex than on leaf nodes. Say that the internal node is node A and that node B is the child of A. (If the insertion is to insert a right child, then B is the right child of A, and similarly with a left child insertion.) A assigns its child to the new node and the new node assigns its parent to A. Then the new node assigns its child to B and B assigns its parent as the new node. Deletion Deletion is the process whereby a node is removed from the tree. Only certain nodes in a binary tree can be removed unambiguously. Node with zero or one children Suppose that the node to delete is node A. If A has no children, deletion is accomplished by setting the child of A's parent to null. If A has one child, set the parent of A's child to A's parent and set the child of A's parent to A's child. Node with two children In a binary tree, a node with two children cannot be deleted unambiguously. However, in certain binary trees (including binary search trees) these nodes can be deleted, though with a rearrangement of the tree structure. Traversal Pre-order, in-order, and post-order traversal visit each node in a tree by recursively visiting each node in the left and right subtrees of the root. Depth-first order In depth-first order, we always attempt to visit the node farthest from the root node that we can, but with the caveat that it must be a child of a node we have already visited. Unlike a depth-first search on graphs, there is no need to remember all the nodes we have visited, because a tree cannot contain cycles. Pre-order is a special case of this. See depth-first search for more information. Breadth-first order Contrasting with depth-first order is breadth-first order, which always attempts to visit the node closest to the root that it has not already visited. See breadth-first search for more information. Also called a level-order traversal. In a complete binary tree, a node's breadth-index (i − (2d − 1)) can be used as traversal instructions from the root. Reading bitwise from left to right, starting at bit d − 1, where d is the node's distance from the root (d = ⌊log(i+1)⌋) and the node in question is not the root itself (d > 0). When the breadth-index is masked at bit d − 1, the bit values and mean to step either left or right, respectively. The process continues by successively checking the next bit to the right until there are no more. The rightmost bit indicates the final traversal from the desired node's parent to the node itself. There is a time-space trade-off between iterating a complete binary tree this way versus each node having pointer/s to its sibling/s. See also References Citations Bibliography Donald Knuth.

Boiled leather, often referred to by its French translation, cuir bouilli (), was a historical material for various uses common in the Middle Ages and Early Modern Period. It was leather that had been treated so that it became tough and rigid, as well as able to hold moulded decoration. It was the usual material for the robust carrying-cases that were made for important pieces of metalwork, instruments such as astrolabes, personal sets of cutlery, books, pens and the like. It was used for some armour, being both much cheaper and much lighter than plate armour, but could not withstand a direct blow from a blade, nor a gunshot. Alternative names are "moulded leather" and "hardened leather". In the course of making the material it becomes very soft, and can be impressed into a mould to give it the desired shape and decoration, which most surviving examples have. Pieces such as chests and coffers also usually have a wooden inner core. Various recipes for making cuir bouilli survive, and do not agree with each other; probably there were a range of recipes, partly reflecting different final uses. Vegetable-tanned leather is generally specified. Scholars have debated the subject at length and attempted to recreate the historical material. Many, but not all, sources agree that actual boiling of the leather was not part of the process, but immersion in water, cold or hot, was. Military use Cuir bouilli was used for cheap and light armour, although it was much less effective than plate armour, which was extremely expensive and too heavy for much to be worn by infantry (as opposed to knights fighting on foot). However, cuir bouilli could be reinforced against slashing blows by the addition of metal bands or strips, especially in helmets. Modern experiments on simple cuir bouilli have shown that it can reduce the depth of an arrow wound considerably, especially if coated with a crushed mineral facing mixed with glue, as one medieval Arab author recommended. In addition, "armour based on hide has the unique advantage that it can, in extremis, provide some nutrition" when actually boiled. Josephus records that the Jewish defenders in the Siege of Jerusalem in AD 70 were reduced to eating their shields and other leather kit, as was the Spanish expedition of Tristan de Luna in 1559. Versions of cuir bouilli were used since ancient times, especially for shields, in many parts of the world. Although in general leather does not survive long burial, and excavated archaeological evidence for it is rare, an Irish shield of cuir bouilli with wooden formers, deposited in a peat bog, has survived for some 2,500 years. It was commonly used in the Western world for helmets; the pickelhaube, the standard German helmet, was not replaced by a steel stahlhelm until 1916, in the midst of World War I. As leather does not conduct heat the way metal does, firemen continued to use boiled leather helmets until World War II, and the invention of strong plastics. The word cuirass for a breastplate indicates that these were originally made of leather. In the Late Middle Ages, the heyday of plate armour, cuir bouilli continued to be used even by the rich for horse armour and often for tournament armour, as well as by ordinary infantry soldiers. Tournaments were increasingly regulated in order to reduce the risk to life, and in 1278 Edward I of England organized one in Windsor Great Park at which cuir bouilli armour was worn, and the king provided swords made of whale bone and parchment. The account of the Battle of Agincourt in 1415 by Jean de Wavrin, who was present on the French side, describes the crucial force of English longbowmen as having on their heads either cuir bouilli helmets, or wicker with iron strips, or nothing (the last, he says, were also barefoot). A few pieces of Roman horse armour in cuir bouilli have been excavated. Evidence from documents such as inventories show that it was common in the late Middle Ages and Renaissance, and used by the highest ranks, but survivals are very few. In 1547 the Master of Armoury in the Tower of London ordered 46 sets of bards and crinets in preparation for the final invasion of Scotland in the war known as the Rough Wooing. In September that year the English cavalry were crucial in the decisive victory at the Battle of Pinkie Cleugh. The German Count Palatine of the Rhine had six sets of cuir bouilli horse armour for his and his family's use in the 16th century. Often the shaffron for the horse's head would be in steel, though leather ones are also known. Cuir bouilli was also very common for scabbards. However surviving specimens of leather armour are rare, more so than the various types of civilian containers. It is believed that many leather pieces are depicted in sculpted tomb monuments, where they are more highly decorated than metal pieces would have been. Cuir bouilli was also often used for elaborate figurative crests on some helmets. The material is mentioned in Froissart's Chronicles of the Hundred Years' War, and Geoffrey Chaucer, in his Canterbury Tales, written in the late 1300s, says of the knight Sir Thopas: (Note: jambeaux are greaves – shin armour). The large decorative crests that came to top some helmets in the late Middle Ages were often made of cuir bouilli, as is the famous example belonging to the Black Prince and hung with other "achievements" over his tomb in Canterbury Cathedral. His wooden shield also has the heraldic animals appliqued in cuir bouilli. Examples of other uses As well as the crests on helmets described above, cuir bouilli was probably used sculpturally in various contexts, over a wood or plaster framework where necessary. When Henry V of England died in France, his effigy in cuir bouilli was placed on top of his coffin for the journey back to England. A near life-size crucifix in the Vatican Museums is in cuir bouilli over wood. This is of special interest to art historians because it was made in 1540 as a replica of a crucifix in silver presented by Charlemagne some 740 years before; an object of great interest as possibly the first of the long line of monumental crucifixes in Western art. In 1540 the original silver was melted down for church plate to replace that looted in the Sack of Rome in 1527. It seems likely that the leather was moulded directly from the original and it is possible that the wooden core underneath is actually the Carolingian original, with the leather replacing the sheets of silver originally fitted over the wood. Cuir bouilli has also been employed to bind books, mainly between the 9th and 14th centuries. Other uses include high boots for especially tough use, which were called "postillion's boots" in England. Another use was for large bottles or jugs called "blackjacks", "bombards" or "costerns". There is an English reference to these from 1373.

Charles Hardin Holley (September 7, 1936 – February 3, 1959), known as Buddy Holly, was an American singer-songwriter who was a central and pioneering figure of mid-1950s rock and roll. He was born in Lubbock, Texas, to a musical family during the Great Depression, and learned to play guitar and sing alongside his siblings. His style was influenced by gospel music, country music, and rhythm and blues acts, which he performed in Lubbock with his friends from high school. He made his first appearance on local television in 1952, and the following year he formed the group "Buddy and Bob" with his friend Bob Montgomery. In 1955, after opening for Elvis Presley, he decided to pursue a career in music. He opened for Presley three times that year; his band's style shifted from country and western to entirely rock and roll. In October that year, when he opened for Bill Haley & His Comets, he was spotted by Nashville scout Eddie Crandall, who helped him get a contract with Decca Records. Holly's recording sessions at Decca were produced by Owen Bradley, who had become famous for producing orchestrated country hits for stars like Patsy Cline. Unhappy with Bradley's musical style and control in the studio, Holly went to producer Norman Petty in Clovis, New Mexico, and recorded a demo of "That'll Be the Day", among other songs. Petty became the band's manager and sent the demo to Brunswick Records, which released it as a single credited to "The Crickets", which became the name of Holly's band. In September 1957, as the band toured, "That'll Be the Day" topped the US and UK singles charts. Its success was followed in October by another major hit, "Peggy Sue". The album The "Chirping" Crickets, released in November 1957, reached number five on the UK Albums Chart. Holly made his second appearance on The Ed Sullivan Show in January 1958 and soon after toured Australia and then the UK. In early 1959, he assembled a new band, consisting of future country music star Waylon Jennings (bass), famed session musician Tommy Allsup (guitar), and Carl Bunch (drums), and embarked on a tour of the midwestern U.S. After a show in Clear Lake, Iowa, he chartered an airplane to travel to his next show, in Moorhead, Minnesota. Soon after takeoff, the plane crashed, killing Holly, Ritchie Valens, The Big Bopper, and pilot Roger Peterson in a tragedy later referred to by Don McLean as "The Day the Music Died" in his song "American Pie". During his short career, Holly wrote and recorded many songs. He is often regarded as the artist who defined the traditional rock-and-roll lineup of two guitars, bass, and drums. He was a major influence on later popular music artists, including Bob Dylan, The Beatles, The Rolling Stones, Eric Clapton, The Hollies (who named themselves in his honor), Elvis Costello, Dave Edmunds, Marshall Crenshaw (who later played Holly), and Elton John. He was among the first artists inducted into the Rock and Roll Hall of Fame, in 1986. Rolling Stone magazine ranked him number 13 in its list of "100 Greatest Artists". Life and career Early life and career (1936–1955) Holly was born Charles Hardin Holley (spelled "-ey") on September 7, 1936, in Lubbock, Texas, the fourth child of Lawrence Odell "L.O." Holley (1901–1985) and Ella Pauline Drake (1902–1990). His elder siblings were Larry (born in 1925), Travis (1927–2016), and Patricia Lou (1929–2008). Buddy Holly was of mostly English and Welsh descent, and had small amounts of Native American ancestry as well. From early childhood, he was nicknamed "Buddy." During the Great Depression, the Holleys frequently moved residence within Lubbock; L.O. changed jobs several times. Buddy Holly was baptized a Baptist, and the family were members of the Tabernacle Baptist Church. The Holleys had an interest in music; all the family members except L.O. were able to play an instrument or sing. The elder Holley brothers performed in local talent shows; on one occasion, Buddy joined them on violin. Since he could not play it, his brother Larry greased the strings so it would not make any sound. The brothers won the contest. During World War II, Larry and Travis were called to military service. Upon his return, Larry brought with him a guitar he had bought from a shipmate while serving in the Pacific. At age 11, Buddy took piano lessons but abandoned them after nine months. He switched to the guitar after he saw a classmate playing and singing on the school bus. Buddy's parents initially bought him a steel guitar, but he insisted that he wanted a guitar like his brother's. His parents bought the guitar from a pawnshop, and Travis taught him to play it. During his early childhood, Holly was influenced by the music of Hank Williams, Jimmie Rodgers, Hank Snow, Bob Wills, and the Carter Family. At Roscoe Wilson Elementary, he became friends with Bob Montgomery, and the two played together, practicing with songs by the Louvin Brothers and Johnnie & Jack. They both listened to the radio programs Grand Ole Opry on WSM, Louisiana Hayride on KWKH, and Big D Jamboree. At the same time, Holly played with other musicians he met in high school, including Sonny Curtis and Jerry Allison. In 1952 Holly and Jack Neal participated as a duo billed as "Buddy and Jack" in a talent contest on a local television show. After Neal left, he was replaced by Bob Montgomery and they were billed as "Buddy and Bob." The two soon started performing on the Sunday Party show on KDAV in 1953 and performed live gigs in Lubbock. At that time, Holley was influenced by late-night radio stations that played blues and rhythm and blues (R&B). Holly would sit in his car with Curtis and tune to distant radio stations that could only be received at night, when local transmissions ceased. Holly then modified his music by blending his earlier country and western (C&W) influence with R & B. By 1955, after graduating from Lubbock High School, Holly decided to pursue a full-time career in music. He was further encouraged after seeing Elvis Presley performing live in Lubbock, whose act was booked by Pappy Dave Stone of KDAV. In February, he opened for Presley at the Fair Park Coliseum, in April at the Cotton Club, and again in June at the Coliseum. By that time, he had incorporated into his band Larry Welborn on the stand-up bass and Allison on drums, as his style shifted from C&W to rock and roll due to seeing Presley's performances and hearing his music. In October, Stone booked Bill Haley & His Comets and placed Holley as the opening act to be seen by Nashville scout Eddie Crandall. Impressed, Crandall persuaded Grand Ole Opry manager Jim Denny to seek a recording contract for Holley. Stone sent a demo tape, which Denny forwarded to Paul Cohen, who signed the band to Decca Records in February 1956. In the contract, Decca misspelled Holly's surname as "Holly," and from then on he was known as "Buddy Holly," instead of the real name "Holley." On January 26, 1956, Holly attended his first formal recording session, which was produced by Owen Bradley. He attended two more sessions in Nashville, but with the producer selecting the session musicians and arrangements, Holly became increasingly frustrated by his lack of creative control. In April 1956, Decca released "Blue Days, Black Nights" as a single, with "Love Me" on the B-side. Denny included Holly on a tour as the opening act for Faron Young. During the tour, they were promoted as "Buddy Holly and the Two Tones," while later Decca called them "Buddy Holly and the Three Tunes." The label later released Holly's second single "Modern Don Juan," backed with "You Are My One Desire." Neither single made an impression. On January 22, 1957, Decca informed Holly his contract would not be renewed, but insisted he could not record the same songs for anyone else for five years. The Crickets (1956–1957) Holly was unhappy with the results of his time with Decca; he was inspired by the success of Buddy Knox's "Party Doll" and Jimmy Bowen's "I'm Stickin' with You", and visited Norman Petty, who had produced and promoted both records. Together with Allison, bassist Joe B. Mauldin, and rhythm guitarist Niki Sullivan, he went to Petty's studio in Clovis, New Mexico. The group recorded a demo of "That'll Be the Day", a song they had previously recorded in Nashville. Now playing lead guitar, Holly achieved the sound he desired. Petty became his manager and sent the record to Brunswick Records in New York City. Holly, still under contract with Decca, could not release the record under his name, so a band name was used; Allison proposed the name "Crickets". Brunswick gave Holly a basic agreement to release "That'll Be the Day", leaving him with both artistic control and financial responsibility for future recordings. Impressed with the demo, the label's executives released it without recording a new version. "I'm Looking for Someone to Love" was the B-side; the single was credited to the Crickets. Petty and Holly later learned that Brunswick was a subsidiary of Decca, which legally cleared future recordings under the name Buddy Holly. Recordings credited to the Crickets would be released on Brunswick, while the recordings under Holly's name were released on another subsidiary label, Coral Records. Holly concurrently held a recording contract with both labels. "That'll Be the Day" was released on May 27, 1957. Petty booked Holly and the Crickets for a tour with Irvin Feld, who had noticed the band after "That'll Be the Day" appeared on the R&B chart. He booked them for appearances in Washington, D.C., Baltimore, and New York City. The band was booked to play at New York's Apollo Theater on August 16–22. During the opening performances, the group did not impress the audience, but they were accepted after they included "Bo Diddley." By the end of their run at the Apollo, "That'll Be the Day" was climbing the charts. Encouraged by the single's success, Petty started to prepare two album releases; a solo album for Holly and another for the Crickets. Holly appeared on American Bandstand, hosted by Dick Clark on ABC, on August 26. Before leaving New York, the band befriended the Everly Brothers. "That'll Be the Day" topped the US "Best Sellers in Stores" chart on September 23 and was number one on the UK Singles Chart for three weeks in November. On September 20, Coral released "Peggy Sue", backed with "Everyday", with Holly credited as the performer. By October, "Peggy Sue" had reached number three on Billboard'''s pop chart and number two on the R&B chart; it peaked at number six on the UK Singles chart. As the success of the song grew, it brought more attention to Holly, with the band at the time being billed as "Buddy Holly and the Crickets" (although never on records during Holly's lifetime; the record labels identified the band as "Buddy Holly and the Crickets" beginning in 1962). In the last week of September, the band members flew to Lubbock to visit their families. Holly's high school girlfriend, Echo McGuire, had left him for a fellow student. Aside from McGuire, Holly had a relationship with Lubbock fan June Clark. After Clark ended their relationship, Holly realized the importance of his relationship with McGuire and considered his relationship with Clark a temporary one. Meanwhile, for their return to recording, Petty arranged a session in Oklahoma City, where he was performing with his own band. While the band drove to the location, the producer set up a makeshift studio. The rest of the songs needed for an album and singles were recorded; Petty later dubbed the material in Clovis. The resulting album, The "Chirping" Crickets, was released on November 27, 1957. It reached number five on the UK Albums Chart. In October, Brunswick released the second single by the Crickets, "Oh, Boy!", with "Not Fade Away" on the B-side. The single reached number 10 on the pop chart and 13 on the R&B chart. Holly and the Crickets performed "That'll Be the Day" and "Peggy Sue" on The Ed Sullivan Show on December 1, 1957. Following the appearance, Niki Sullivan left the group because he was tired of the intensive touring, and he wanted to resume his education. On December 29 Holly and the Crickets performed "Peggy Sue" on The Arthur Murray Party. International tours and split (1958) On January 8, 1958, Holly and the Crickets joined America's Greatest Teenage Recording Stars tour. On January 25, Holly recorded "Rave On"; the next day, he made his second appearance on The Ed Sullivan Show, singing "Oh, Boy!" He departed to perform in Honolulu, Hawaii, on January 27, and then started a week-long tour of Australia billed as the Big Show with Paul Anka, Jerry Lee Lewis and Jodie Sands . In March, the band toured the United Kingdom, playing 50 shows in 25 days. The same month, his debut solo album, Buddy Holly, was released. Upon their return to the United States, Holly and the Crickets joined Alan Freed's Big Beat Show tour for 41 dates. In April, Decca released That'll Be the Day, featuring the songs recorded with Bradley during his early Nashville sessions. A new recording session in Clovis was arranged in May; Holly hired Tommy Allsup to play lead guitar. The session produced the recordings of "It's So Easy" and "Heartbeat". Holly was impressed by Allsup and invited him to join the Crickets. In June, Holly traveled alone to New York for a solo recording session. Without the Crickets, he chose to be backed by a jazz and R&B band, recording "Now We're One" and Bobby Darin's "Early in the Morning". During a visit to the offices of Peer-Southern, Holly met María Elena Santiago. He asked her out on their first meeting and proposed marriage to her on their first date. The wedding took place on August 15. Holly's manager Norman Petty disapproved of the marriage and advised Holly to keep it secret to avoid upsetting Holly's female fans. Petty's suggestion created friction with Holly, who had also started to question Petty's bookkeeping. The Crickets were also frustrated with Petty, who controlled all of the proceeds earned by the band. Holly and Santiago frequented many of New York's music venues, including the Village Gate, Blue Note, Village Vanguard, and Johnny Johnson's. Santiago later said that Holly was keen to learn fingerstyle flamenco guitar and that he would often visit her aunt's home to play the piano there. Holly planned collaborations between soul singers and rock and roll. He wanted to make an album with Ray Charles and Mahalia Jackson. He also had ambitions to work in film and registered for acting classes with Lee Strasberg's Actors Studio. Santiago accompanied Holly on tours. To hide her marriage to Holly, she was presented as the Crickets' secretary. She took care of the laundry and equipment set-up and collected the concert revenues. Santiago kept the money for the band instead of their habitual transfer to Petty in New Mexico. She and her aunt Provi Garcia, an executive in the Latin American music department at Peer-Southern, convinced Holly that Petty was paying the band's royalties from Coral-Brunswick into his own company's account. Holly planned to retrieve his royalties from Petty and to later fire him as manager and producer. At the recommendation of the Everly Brothers, Holly hired lawyer Harold Orenstein to negotiate his royalties. The problems with Petty were triggered after he was unable to pay Holly. At the time, New York promoter Manny Greenfield reclaimed a large part of Holly's earnings; Greenfield had booked Holly for shows during previous tours. The two had a verbal agreement; Greenfield would obtain 5% of the booking earnings. Greenfield later felt he was also acting as Holly's manager and deserved a higher payment, which Holly refused. Greenfield then sued Holly. Under New York law, because Holly's royalties originated in New York and were directed out of the state, the payments were frozen until the dispute was settled. Petty then could not complete the transfers to Holly, who considered him responsible for the missing profit. In September, Holly returned to Clovis for a new recording session, which yielded "Reminiscing" and "Come Back Baby". During the session, he ventured into producing by recording Lubbock DJ Waylon Jennings. Holly produced the single "Jole Blon" and "When Sin Stops (Love Begins)" for Jennings. Holly became increasingly interested in the New York music, recording, and publishing scene. Holly and Santiago settled in Apartment 4H of the Brevoort Apartments, at 11 Fifth Avenue in Greenwich Village, where he recorded a series of acoustic songs, including "Crying, Waiting, Hoping" and "What to Do". The inspiration to record the songs is sometimes attributed to the ending of his relationship with McGuire. On October 21, 1958, Holly's final studio session was recorded at the Pythian Temple on West 70th Street (now a luxury condominium). Known by Holly fans as "the string sessions," Holly recorded four songs for Coral in an innovative collaboration with the Dick Jacobs Orchestra, an 18-piece ensemble composed of former members of the NBC Symphony Orchestra including saxophonist Boomie Richman. The four songs recorded during the 3-1/2-hour session were: "True Love Ways" (written by Buddy Holly), "Moondreams" (written by Norman Petty), "Raining in My Heart" (written by Felice and Boudleaux Bryant) and "It Doesn't Matter Anymore" (written by Paul Anka). These four songs were the only ones Holly ever recorded in stereo, but only "Raining in My Heart" was released that way (in 1959, on an obscure promotional LP titled Hitsville). All four records otherwise received releases in mono. The original stereo mixes were consulted many years later for compilation albums. Holly ended his association with Petty in December 1958. His band members kept Petty as their manager and split from Holly. The split was amicable and based on logistics: Holly had decided to settle permanently in New York, where the business and publishing offices were, and the Crickets preferred not to leave their home state. Petty was still holding the money from the royalties, forcing Holly to form a new band and return to touring. Winter Dance Party tour and death (1959) Holly vacationed with his wife in Lubbock and visited Jennings's radio station in December 1958. For the start of the Winter Dance Party tour, he assembled a band consisting of Waylon Jennings (electric bass), Tommy Allsup (guitar), and Carl Bunch (drums). Holly and Jennings left for New York City, arriving on January 15, 1959. Jennings stayed at Holly's apartment by Washington Square Park on the days prior to a meeting scheduled at the headquarters of the General Artists Corporation, which organized the tour. They then traveled by train to Chicago to join the rest of the band. The Winter Dance Party tour began in Milwaukee, Wisconsin, on January 23, 1959. The amount of travel involved created logistical problems, as the distance between venues had not been considered when scheduling performances. Adding to the problem, the unheated tour buses twice broke down in freezing weather, with dire consequences. Holly's drummer Carl Bunch was hospitalized for frostbite to his toes (suffered while aboard the bus), so Holly decided to seek other transportation. On February 2, before their appearance in Clear Lake, Iowa, Holly chartered a four-seat Beechcraft Bonanza airplane for Jennings, Allsup, and himself, from Dwyer Flying Service in Mason City, Iowa. Holly's idea was to depart following the show at the Surf Ballroom in Clear Lake and fly to their next venue, in Moorhead, Minnesota, via Fargo, North Dakota, allowing them time to rest and launder their clothes and avoid a rigorous bus journey. Immediately after the Clear Lake show (which ended just before midnight), Allsup agreed to flip a coin for the seat with Valens. Valens called heads; when he won, he reportedly said, "That's the first time I've ever won anything in my life." Allsup later opened a restaurant in Fort Worth, Texas, called Heads Up. Waylon Jennings voluntarily gave up his seat to J. P. Richardson (the Big Bopper), who had influenza and complained that the tour bus was too cold and uncomfortable for a man of his size. The pilot, Roger Peterson, took off in inclement weather, even though he was not certified to fly by instruments only. Buddy's brother Larry Holley said, "I got the full report from the Civil Aeronautics -- it took me a year to get it, but I got it -- and they had installed a new Sperry gyroscope in the airplane. The Sperry works different than any other gyro. One of them, the background moves and the plane stays like this [stationary], and in the other one the background stays steady and the plane moves, it works just backwards. He [the pilot] could have been reading this backwards... they were going down, they thought they were still climbing." Shortly after 12:55 am on February 3, 1959, Holly, Valens, Richardson, and Peterson were killed instantly when the aircraft crashed into a frozen cornfield five miles northwest of Mason City, Iowa airport shortly after takeoff. The three musicians, who were ejected from the fuselage upon impact, suffered severe head and chest injuries. Holly was 22 years old. Holly's funeral was held on February 7, 1959, at the Tabernacle Baptist Church in Lubbock. The service was officiated by Ben D. Johnson, who had presided at the Hollys' wedding just months earlier. The pallbearers were Jerry Allison, Joe B. Mauldin, Niki Sullivan, Bob Montgomery, and Sonny Curtis. Some sources say that Phil Everly, one half of The Everly Brothers, was also pallbearer, but he said at one time that he attended the funeral but was not a pallbearer. Waylon Jennings was unable to attend, because of his commitment to the still-touring Winter Dance Party. Holly's body was interred in the City of Lubbock Cemetery, in the eastern part of the city. His headstone carries the correct spelling of his surname (Holley) and a carving of his Fender Stratocaster guitar. Santiago watched the first reports of Holly's death on television. The following day, she claimed, she suffered a miscarriage. Holly's mother, who heard the news on the radio in Lubbock, Texas, screamed and collapsed. Because of Elena's miscarriage, in the months following the accident, the authorities implemented a policy against announcing victims' names until after families are informed. Santiago did not attend the funeral and has never visited the grave site. She later told the Avalanche-Journal, "In a way, I blame myself. I was not feeling well when he left. I was two weeks pregnant, and I wanted Buddy to stay with me, but he had scheduled that tour. It was the only time I wasn't with him. And I blame myself because I know that, if only I had gone along, Buddy never would have gotten into that airplane." Image and style Holly's singing style was characterized by his vocal hiccups and his alternation between his regular voice and falsetto. His "stuttering vocals" were complemented by his percussive guitar playing, solos, stops, bent notes, and rhythm and blues chord progressions. He often strummed downstrokes that were accompanied by Allison's "driving" percussion. Holly bought his first Fender Stratocaster, which became his signature guitar, at Harrod Music in Lubbock for US$249.50. Fender Stratocasters were popular with country musicians; Holly chose it for its loud sound. His "innovative" playing style was characterized by its blending of "chunky rhythm" and "high string lead work". He played his first Stratocaster, a 1954 model, until it was stolen during a tour stop in Michigan in 1957. To replace it, he purchased a 1957 model before a show in Detroit. Holly owned four or five Stratocasters during his career. At the beginning of their music careers, Holly and his band wore business suits. When they met the Everly Brothers, Don Everly took the band to Phil's men's shop in New York City and introduced them to Ivy League clothes. The brothers advised Holly to replace his old-fashioned glasses with horn-rimmed glasses, which had been popularized by Steve Allen. Holly bought a pair of glasses made in Mexico from Lubbock optometrist Dr. J. Davis Armistead. Teenagers in the United States started to request this style of glasses, which were later popularly known as "Buddy Holly glasses". When the plane crashed, the wreckage was strewn across many yards of snow-covered ground. While his other belongings were recovered immediately, there was no record of his signature glasses being found. They were presumed lost until, in March 1980, they were discovered in a Cerro Gordo County courthouse storage area by Sheriff Gerald Allen. They had been found in the spring of 1959, after the snow had melted, and had been given to the sheriff's office. They were placed in an envelope dated April 7, 1959, along with the Big Bopper's watch, a lighter, two pairs of dice and part of another watch, and misplaced when the county moved courthouses. The glasses, missing their lenses, were returned to Santiago a year later, after a legal contest over them with his parents. They are now on display at the Buddy Holly Center in Lubbock, Texas. Legacy Buddy Holly left behind dozens of unfinished recordings — solo transcriptions of his new compositions, informal jam sessions with bandmates, or tapes demonstrating songs intended for other artists. The most recent recordings, made in Holly's apartment in late 1958, were his last six original songs. In June 1959, Coral Records overdubbed two of them with backing vocals by the Ray Charles Singers and studio musicians in an attempt to simulate the established Crickets sound. The finished tracks became the first posthumous Holly single, "Peggy Sue Got Married"/"Crying, Waiting, Hoping". The new release was successful enough to warrant an album drawing upon the other Holly demos, using the same studio personnel, in January 1960. All six songs were included in The Buddy Holly Story, Vol. 2 (1960). The demand for Holly records was so great, and Holly had recorded so prolifically, that his record label was able to release new Holly albums and singles for the next 10 years. Norman Petty produced most of these new editions, drawing upon unreleased studio masters, alternate takes, audition tapes, and even amateur recordings (some dating back to 1954 with low-fidelity vocals). The final "new" Buddy Holly album, Giant, was released in 1969; the single chosen from the album was "Love Is Strange". Encyclopædia Britannica stated that Holly "produced some of the most distinctive and influential work in rock music". AllMusic defined him as "the single most influential creative force in early rock and roll". Rolling Stone ranked him number 13 on its list of "100 Greatest Artists". The Telegraph called him a "pioneer and a revolutionary [...] a multidimensional talent [...] (who) co-wrote and performed (songs that) remain as fresh and potent today". The Rock and Roll Hall of Fame included Holly among its first class in 1986. On its entry, the Hall of Fame remarked upon the large quantity of material he produced during his short musical career, and said it "made a major and lasting impact on popular music". It called him an "innovator" for writing his own material, his experimentation with double tracking and the use of orchestration; he is also said to have "pioneered and popularized the now-standard" use of two guitars, bass, and drums by rock bands. The Songwriters Hall of Fame also inducted Holly in 1986, and said his contributions "changed the face of Rock 'n' Roll". Holly developed in collaboration with Petty techniques of overdubbing and reverb, while he used innovative instrumentation later implemented by other artists. Holly became "one of the most influential pioneers of rock and roll" who had a "lasting influence" on genre performers of the 1960s. In 1980, Grant Speed sculpted a statue of Holly playing his Fender guitar. This statue is the centerpiece of Lubbock's Walk of Fame, which honors notable people who contributed to Lubbock's musical history. Other memorials to Buddy Holly include a street named in his honor and the Buddy Holly Center, which contains a museum of Holly memorabilia and fine arts gallery. The Center is located on Crickets Avenue, one street east of Buddy Holly Avenue, in a building that previously housed the Fort Worth and Denver South Plains Railway Depot. In 1997, the National Academy of Recording Arts and Sciences gave Holly the Lifetime Achievement Award. Holly was inducted into the Iowa Rock 'n' Roll Hall of Fame in 2000. In 2010, Grant Speed's statue was taken down for refurbishment and construction of a new Walk of Fame began. On May 9, 2011, the City of Lubbock held a ribbon-cutting ceremony for the Buddy and Maria Elena Holly Plaza, the new home of the statue and the Walk of Fame. The same year, a star bearing Holly's name was placed on the Hollywood Walk of Fame, commemorating his 75th birthday. Groundbreaking was held on April 20, 2017, for the construction of a new performing arts center in Lubbock, the Buddy Holly Hall of Performing Arts and Sciences, a downtown $153 million project expected to be completed in 2020. Thus far, the private group, the Lubbock Entertainment and Performing Arts Association, has raised or received pledges in the amount of $93 million to underwrite the project. According to a June 2019 article in The New York Times Magazine, "virtually all of Holly's masters were lost" in the 2008 Universal fire. This is disputed by Chad Kassem of Analogue Productions, who claims to have used the master tapes of Holly's first two albums in Analogue Productions reissues of these albums on LP and SACD in 2017. Influence John Lennon and Paul McCartney saw Holly for the first time when he appeared on Sunday Night at the London Palladium. The two had recently met and begun their musical association. They studied Holly's records, learned his performance style and lyricism, and based their act around his persona. Inspired by Holly's insect-themed Crickets, they chose to name their band "The Beatles". Lennon and McCartney later cited Holly as one of their main influences. Lennon's band the Quarrymen covered "That'll Be the Day" in their first recording session, in 1958. During breaks in the Beatles' first appearance on The Ed Sullivan Show, on February 9, 1964, Lennon asked CBS coordinator Vince Calandra about Holly's performances; Calandra said Lennon and McCartney repeatedly expressed their appreciation of Holly. The Beatles recorded a close cover of Holly's version of "Words of Love", which was released on their 1964 album Beatles for Sale (in the U.S., in June 1965 on Beatles VI). During the January 1969 recording sessions for their album Let It Be, the Beatles played a slow, impromptu version of "Mailman, Bring Me No More Blues" – which Holly popularized but did not write – with Lennon mimicking Holly's vocal style. Lennon recorded a cover version of "Peggy Sue" on his 1975 album Rock 'n' Roll. McCartney owns the publishing rights to Holly's song catalogue. On January 31, 1959, two nights before Holly's death, 17-year-old Bob Dylan attended Holly's performance in Duluth. Dylan referred to this in his acceptance speech when he received the Grammy Award for Album of the Year for Time Out of Mind in 1998: "... when I was sixteen or seventeen years old, I went to see Buddy Holly play at Duluth National Guard Armory and I was three feet away from him ... and he looked at me. And I just have some sort of feeling that he was ... with us all the time we were making this record in some kind of way". Mick Jagger saw Holly performing live in Woolwich, London, during a tour of England; Jagger particularly remembered Holly's performance of "Not Fade Away" – a song that also inspired Keith Richards, who modeled his early guitar playing on the track. The Rolling Stones had a hit version of the song in 1964. Richards later said, "[Holly] passed it on via the Beatles and via [the Rolling Stones] ... He's in everybody". Don McLean's popular 1971 ballad "American Pie" was inspired by Holly's death and the day of the plane crash. The song's lyric, which calls the incident "The Day the Music Died", became popularly associated with the crash. McLean's album American Pie is dedicated to Holly. In 2015, McLean wrote, "Buddy Holly would have the same stature musically whether he would have lived or died, because of his accomplishments ... By the time he was 22 years old, he had recorded some 50 tracks, most of which he had written himself ... in my view and the view of many others, a hit ... Buddy Holly and the Crickets were the template for all the rock bands that followed". Elton John was musically influenced by Holly. At age 13, although he did not require them, John started wearing horn-rimmed glasses to imitate Holly. The Clash were also influenced by Holly, and referenced him in their song "If Music Could Talk" from the Sandinista! album. The Chirping Crickets was the first album Eric Clapton ever bought; he later saw Holly on Sunday Night at the London Palladium. In his autobiography, Clapton recounted the first time he saw Holly and his Fender, saying, "I thought I'd died and gone to heaven ... it was like seeing an instrument from outer space and I said to myself: 'That's the future – that's what I want'". The launch of Bobby Vee's successful musical career resulted from Holly's death; Vee was selected to replace Holly on the tour that continued after the plane crash. Holly's profound influence on Vee's singing style can be heard in the songs "Rubber Ball" – the B-side of which was a cover of Holly's "Everyday" – and "Run to Him." The name of the British rock band the Hollies is often claimed as a tribute to Holly; according to the band, they admired Holly, but their name was mainly inspired by sprigs of holly in evidence around Christmas 1962. In an August 24, 1978, interview with Rolling Stone, Bruce Springsteen told Dave Marsh, "I play Buddy Holly every night before I go on; that keeps me honest". The Grateful Dead performed the song "Not Fade Away" in concerts. In 2016, Richard Barone released his album Sorrows & Promises: Greenwich Village in the 1960s, paying tribute to the new wave of singer-songwriters in the Village during that pivotal, post-Holly era. The album opens with Barone's version of "Learning the Game", one of the final songs written and recorded by Holly at his home in Greenwich Village, a week before his death. Film and musical depictions Holly's life story inspired a Hollywood biographical film, The Buddy Holly Story (1978); its lead actor Gary Busey received a nomination for the Academy Award for Best Actor for his portrayal of Holly. The film was widely criticized by the rock press, and by Holly's friends and family, for its inaccuracies. This led Paul McCartney (whose MPL Communications by then controlled the publishing rights to Buddy Holly's song catalog) to produce and host his own documentary about Holly in 1985, titled The Real Buddy Holly Story. This video includes interviews with Keith Richards, Phil and Don Everly, Sonny Curtis, Jerry Allison, Holly's family, and McCartney, among others. In 1987, musician Marshall Crenshaw portrayed Buddy Holly in the movie La Bamba, which depicts him performing at the Surf Ballroom and boarding the fatal airplane with Ritchie Valens and the Big Bopper. Crenshaw's version of "Crying, Waiting, Hoping" is featured on the La Bamba original motion picture soundtrack.Buddy – The Buddy Holly Story, a jukebox musical depicting Holly's life, opened in 1989. Holly was depicted in a 1989 episode of the science-fiction television program Quantum Leap titled "How the Tess Was Won"; Holly's identity is only revealed at the end of the episode. Dr. Sam Beckett (Scott Bakula) influences Buddy Holly to change his lyrics from "piggy, suey" to "Peggy Sue", setting up Holly's future hit song. Holly's follow up to that hit song is featured in the 1986 Francis Ford Coppola film Peggy Sue Got Married, in which a 43-year-old mother and housewife facing divorce played by Kathleen Turner is thrust back in time and given the chance to change the course of her life. Steve Buscemi appeared as Holly in a brief cameo as a 1950s-themed restaurant employee in Quentin Tarantino's 1994 film Pulp Fiction, in which he takes Mia Wallace and Vincent Vega's orders (portrayed respectively by Uma Thurman and John Travolta). In 1961 Mike Berry recorded "Tribute to Buddy Holly". In 1985, the German punk band Die Ärzte composed a song centering on Buddy Holly's glasses, titled "Buddy Holly's Brille". In 1998, the post-apocalyptic film Six String Samurai depicted Buddy Holly as a guitar-playing samurai traveling to Las Vegas to become the new king of Nevada after the death of Elvis Presley. Weezer's first top 40 single in the US was titled "Buddy Holly". In 2006, country band, the Dixie Chicks mention Buddy Holly in their song Lubbock or Leave It. Lead singer, Natalie Maines, and Holly share a hometown, Lubbock, Texas. Musician Richard Barone recorded one of Buddy Holly's Greenwich Village demos, "Learning the Game" on his 2016 album Sorrows & Promises. In concert, Barone speaks of the importance of Holly's presence in the Village at the end of 1950s, speculating that had he lived, Holly would have expedited the folk rock and singer-songwriter movements that emerged in the mid-1960s.

Babrak Karmal (Dari/Pashto , born Sultan Hussein; 6 January 1929 – 1 or 3 December 1996) was an Afghan revolutionary and politician who was the leader of Afghanistan, serving in the post of General Secretary of the People's Democratic Party of Afghanistan for seven years. Born in Kabul Province into a Tajikized family of Kashmiri origin, Karmal attended Kabul University and developed openly leftist views there, having been introduced to Marxism by Mir Akbar Khyber during his imprisonment for activities deemed too radical by the government. He became a founding member of the People's Democratic Party of Afghanistan (PDPA) and eventually became the leader of the Parcham faction when the PDPA split in 1967, with their ideological nemesis being the Khalq faction. Karmal was elected to the Lower House after the 1965 parliamentary election, serving in parliament until losing his seat in the 1969 parliamentary election. Under Karmal's leadership, the Parchamite PDPA participated in Mohammad Daoud Khan's rise to power in 1973, and his subsequent regime. While relations were good at the beginning, Daoud began a major purge of leftist influence in the mid-1970s. This in turn led to the reformation of the PDPA in 1977, and Karmal played a role in the 1978 Saur Revolution when the PDPA took power. Karmal was appointed Deputy Chairman of the Revolutionary Council, synonymous with vice head of state, in the communist government. The Parchamite faction found itself under significant pressure by the Khalqists soon after taking power. In June 1978, a PDPA Central Committee meeting voted in favor of giving the Khalqist faction exclusive control over PDPA policy. This decision was followed by a failed Parchamite coup, after which Hafizullah Amin, a Khalqist, initiated a purge against the Parchamites. Karmal survived this purge but was exiled to Prague and eventually dismissed from his post. Instead of returning to Kabul, he feared for his life and lived with his family in the forests protected by the Czechoslovak secret police StB. The Afghan secret police KHAD had allegedly sent members to Czechoslovakia to assassinate Karmal. In late 1979 he was brought to Moscow by the KGB and eventually, in December 1979, the Soviet Union intervened in Afghanistan (with the consent of Amin's government) to stabilize the country. The Soviet troops staged a coup and assassinated Amin, replacing him with Karmal. Karmal was promoted to Chairman of the Revolutionary Council and Chairman of the Council of Ministers on 27 December 1979. He remained in the latter office until 1981, when he was succeeded by Sultan Ali Keshtmand. Throughout his term, Karmal worked to establish a support base for the PDPA by introducing several reforms. Among these were the "Fundamental Principles of the Democratic Republic of Afghanistan", introducing a general amnesty for those people imprisoned during Nur Mohammad Taraki's and Amin's rule. He also replaced the red Khalqist flag with a more traditional one. These policies failed to increase the PDPA's legitimacy in the eyes of the Afghan people and the Afghan mujahideen rebels - he was widely seen as a Soviet puppet amongst the populace. These policy failures, and the stalemate that ensued after the Soviet intervention, led the Soviet leadership to become highly critical of Karmal's leadership. Under Mikhail Gorbachev, the Soviet Union deposed Karmal in 1986 and replaced him with Mohammad Najibullah. Following his loss of power, he was again exiled, this time to Moscow. It was Anahita Ratebzad who persuaded Najibullah to allow Babrak Karmal to return to Afghanistan in 1991, where Karmal became an associate of Abdul Rashid Dostum and possibly helped remove the Najibullah government from power in 1992. He eventually left Afghanistan again for Moscow. Not long after, in 1996, Karmal died from liver cancer. Early life and career Karmal was born Sultan Hussein on 6 January 1929 in Kamari, a village close to Kabul. He was the son of Muhammad Hussein Hashem, a Major General in the Afghan Army and former governor of the province of Paktia, and was the second of five siblings. His family was one of the wealthier families in Kabul. His ethnic background was publicly disputed at the time, with many sources reporting he was a Tajik of Kabul. In 1986, Karmal declared that he and his brother Mahmud Baryalay were Pashtuns as their mother was a linguistically Persianized Pashtun of the Khilji tribe. This declaration was considered to be political as descent comes from the patriarchal line in Afghan society. Karmal's forefathers came to Kabul from Kashmir, and his original name Sultan Hussein (which is associated with Indian Muslims) reinforces his Kashmiri roots. He attended Nejat High School, a German-speaking school, and graduated from it in 1948, and applied to enter the Faculty of Law and Political Science of Kabul University. Karmal's application was initially denied admission to Kabul University because of his student political activist and his openly leftist views. He was always a charismatic speaker and became involved in the student union and the Wikh-i-Zalmayan (Awakened Youth Movement), a progressive and leftist organization. He studied at the College of Law and Political Science at Kabul University from 1951 to 1953. In 1953 Karmal was arrested because of his student union activities, but was released three years later in 1956 in an amnesty by Muhammad Daoud Khan. Shortly after, in 1957, Karmal found work as an English and German translator, before quitting and leaving for military training. Karmal graduated from the College of Law and Political Science in 1960, and in 1961, he found work as an employee in the Compilation and Translation Department of the Ministry of Education. From 1961 to 1963 he worked in the Ministry of Planning. When his mother died, Karmal left with his maternal aunt to live somewhere else. His father disowned him because of his leftist views. Karmal was involved in much debauchery, which was controversial in the mostly conservative Afghan society. Communist politics Imprisoned from 1953 to 1956, Karmal befriended fellow inmate Mir Akbar Khyber, who introduced Karmal to Marxism. Karmal changed his name from Sultan Hussein to Babrak Karmal, which means "Comrade of the Workers'" in Pashtun, to disassociate himself from his bourgeois background. When he was released from prison, he continued his activities in the student union, and began to promote Marxism. Karmal spent the rest of the 1950s and the early 1960s becoming involved with Marxist organizations, of which there were at least four in Afghanistan at the time; two of the four were established by Karmal. When the 1964 Afghan Provisional Constitution, which legalised the establishment of new political entities, was introduced several prominent Marxists agreed to establish a communist political party. The People's Democratic Party of Afghanistan (PDPA, the Communist Party) was established in January 1965 in Nur Muhammad Taraki's home. Factionalism within the PDPA quickly became a problem; the party split into the Khalq led by Taraki alongside Hafizullah Amin, and the Parcham led by Karmal. During the 1965 parliamentary election Karmal was one of four PDPA members elected to the lower house of parliament; the three others were Anahita Ratebzad, Nur Ahmed Nur and Fezanul Haq Fezan. No Khalqists were elected; however, Amin was 50 votes short of being elected. The Parchamite victory may be explained by the simple fact that Karmal could contribute financially to the PDPA electoral campaign. Karmal became a leading figure within the student movement in the 1960s, electing Mohammad Hashim Maiwandwal as Prime Minister after a student demonstration (called for by Karmal) concluded with three deaths under the former leadership. In 1966 inside parliament, Karmal was physically assaulted by an Islamist MP, Mohammad Nabi Mohammadi. In 1967, the PDPA unofficially split into two formal parties, one Khalqist and one Parchamist. The dissolution of the PDPA was initiated by the closing down of the Khalqist newspaper, Khalq. Karmal criticised the Khalq for being too communist, and believed that its leadership should have hidden its Marxist orientation instead of promoting it. According to the official version of events, the majority of the PDPA Central Committee rejected Karmal's criticism. The vote was a close one, and it is reported that Taraki expanded the Central Committee to win the vote; this plan resulted in eight of the new members becoming politically unaligned with and one switching to the Parchamite side. Karmal and half the PDPA Central Committee left the PDPA to establish a Parchamite-led PDPA. Officially the split was caused by ideological differences, but the party may have divided between the different leadership styles and plans of Taraki versus Karmal. Taraki wanted to model the party after Leninist norms while Karmal wanted to establish a democratic front. Other differences were socioeconomic. The majority of Khalqists came from rural areas; hence they were poorer, and were of Pashtun origin. The Parchamites were urban, richer, and spoke Dari more often than not. The Khalqists accused the Parchamites of having a connection with the monarchy, and because of it, referred to the Parchamite PDPA as the "Royal Communist Party". Both Karmal and Amin retained their seats in the lower house of parliament in the 1969 parliamentary election. The Daoud era Mohammed Daoud Khan, in collaboration with the Parchamite PDPA and radical military officers, overthrew the monarchy and instituted the Republic of Afghanistan in 1973. After Daoud's seizure of power, an American embassy cable stated that the new government had established a Soviet-style Central Committee, in which Karmal and Mir Akbar Khyber were given leading positions. Most ministries were given to Parchamites; Hassan Sharq became Deputy Prime Minister, Major Faiz Mohammad became Minister of Internal Affairs and Niamatullah Pazhwak became Minister of Education. The Parchamites took control over the ministries of finance, agriculture, communications and border affairs. The new government quickly suppressed the opposition, and secured their power base. At first, the National Front government between Daoud and the Parchamites seemed to work. By 1975, Daoud had strengthened his position by enhancing the executive, legislative and judicial powers of the Presidency. To the dismay of the Parchamites, all parties other than the National Revolutionary Party (NRP, established by Daoud) were made illegal. Shortly after the ban on opposition to the NRP, Daoud began a massive purge of Parchamites in government. Mohammad lost his position as interior minister, Abdul Qadir was demoted, and Karmal was put under government surveillance. To mitigate Daoud's suddenly anti-communist directives, the Soviet Union reestablished the PDPA; Taraki was elected its General Secretary and Karmal, Second Secretary. While the Saur Revolution (literally the April Revolution) was planned for August, the assassination of Khyber led to a chain of events which ended with the communists seizing power. Karmal, when taking power in 1979, accused Amin of ordering the assassination of Khyber. Taraki–Amin rule Taraki was appointed Chairman of the Presidium of the Revolutionary Council and Chairman of the Council of Ministers, retaining his post as PDPA general secretary. Taraki initially formed a government which consisted of both Khalqists and Parchamites; Karmal became Deputy Chairman of the Revolutionary Council, while Amin became Minister of Foreign Affairs and Deputy Chairman of the Council of Ministers.Mohammad Aslam Watanjar became Deputy Chairman of the Council of Ministers. The two Parchamites Abdul Qadir and Mohammad Rafi, became Minister of Defence and Minister of Public Works, respectively. The appointment of Amin, Karmal and Watanjar led to splits within the Council of Ministers: the Khalqists answered to Amin; Karmal led the civilian Parchamites; and the military officers (who were Parchamites) were answerable to Watanjar (a Khalqist). The first conflict arose when the Khalqists wanted to give PDPA Central Committee membership to military officers who had participated in the Saur Revolution; Karmal opposed such a move but was overruled. A PDPA Politburo meeting voted in favour of giving Central Committee membership to the officers. On 27 June, three months after the Saur Revolution, Amin outmaneuvered the Parchamites at a Central Committee meeting, giving the Khalqists exclusive right over formulating and deciding policy. A purge against the Parchamites was initiated by Amin and supported by Taraki on 1 July 1979. Karmal, fearing for his safety, went into hiding in one of his Soviet friends' homes. Karmal tried to contact Alexander Puzanov, the Soviet ambassador to Afghanistan, to talk about the situation. Puzanov refused, and revealed Karmal's location to Amin. The Soviets probably saved Karmal's life by sending him to the Socialist Republic of Czechoslovakia. In exile, Karmal established a network with the remaining Parchamites in government. A coup to overthrow Amin was planned for 4 September 1979. Its leading members in Afghanistan were Qadir and the Army Chief of Staff General Shahpur Ahmedzai. The coup was planned for the Festival of Eid, in anticipation of relaxed military vigilance. The conspiracy failed when the Afghan ambassador to India told the Afghan leadership about the plan. Another purge was initiated, and Parchamite ambassadors were recalled. Few returned to Afghanistan; Karmal and Mohammad Najibullah stayed in their respective countries. The Soviets decided that Amin should be removed to make way for a Karmal-Taraki coalition government. However Amin managed to order the arrest and later the murder of Taraki. Amin was informed of the Soviet decision to intervene in Afghanistan and was initially supportive, but was assassinated. Under the command of the Soviets, Karmal ascended to power. On 27 December 1979, Karmal's pre-recorded speech to the Afghan people was broadcast via Radio Kabul from Tashkent in the Uzbek SSR (the radio wavelength was changed to that of Kabul), saying: "Today the torture machine of Amin has been smashed, his accomplices – the primitive executioners, usurpers and murderers of tens of thousand of our fellow countrymen – fathers, mothers, sisters, brothers, sons and daughters, children and old people ..." Karmal was not in Kabul when the speech was broadcast; he was in Bagram, protected by the KGB. That evening Yuri Andropov, the KGB Chairman, congratulated Karmal on his rise to the Chairmanship of the Presidium of the Revolutionary Council, some time before Karmal received an official appointment. Karmal returned to Kabul on 28 December. He travelled alongside a Soviet military column. For the next few days Karmal lived in a villa on the outskirts of Kabul under the protection of the KGB. On 1 January 1980 Leonid Brezhnev, the General Secretary of the Central Committee of the Communist Party of the Soviet Union, and Alexei Kosygin, the Soviet Chairman of the Council of Ministers, congratulated Karmal on his "election" as leader. Leadership Domestic policies Karmal's ascension was quickly troubled as he was effectively installed by the invading Soviet Union, delegitimizing him. Unrest in the country quickly escalated, and in Kabul two major uprisings, on 3 Hoot (22 February) and the months long students' protests were early signs of trouble. The "Fundamental Principles" and amnesty When he came to power, Karmal promised an end to executions, the establishment of democratic institutions and free elections, the creation of a constitution, and legalization of alternative political parties. Prisoners incarcerated under the two previous governments would be freed in a general amnesty (which occurred on 6 January). He promised the creation of a coalition government which would not espouse socialism. At the same time, he told the Afghan people that he had negotiated with the Soviet Union to give economic, military and political assistance. The mistrust most Afghans felt towards the government was a problem for Karmal. Many still remembered he had said he would protect private capital in 1978—a promise later proven to be a lie. Karmal's three most important promises were the general amnesty of prisoners, the promulgation of the Fundamental Principles of the Democratic Republic of Afghanistan and the adoption of a new flag containing the traditional black, red and green (the flag of Taraki and Amin was red). His government granted concessions to religious leaders and the restoration of confiscated property. Some property, which was confiscated during earlier land reforms, was also partially restored. All these measures, with the exception of the general amnesty of prisoners, were introduced gradually. Of 2,700 prisoners, 2,600 were released from prison; 600 of these were Parchamites. The general amnesty was greatly publicized by the government. While the event was hailed with enthusiasm by some, many others greeted the event with disdain, since their loved ones or associates had died during earlier purges. Amin had planned to introduce a general amnesty on 1 January 1980, to coincide with the PDPA's sixteenth anniversary. Work on the Fundamental Principles had started under Amin: it guaranteed democratic rights such as freedom of speech, the right to security and life, the right to peaceful association, the right to demonstrate and the right that "no one would be accused of crime but in accord with the provisions of law" and that the accused had the right to a fair trial. The Fundamental Principles envisaged a democratic state led by the PDPA, the only party then permitted by law. The Revolutionary Council, the organ of supreme power, would convene twice every year. The Revolutionary Council in turn elected a Presidium which would take decisions on behalf of the Revolutionary Council when it was not in session. The Presidium consisted mostly of PDPA Politburo members. The state would safeguard three kinds of property: state, cooperative and private property. The Fundamental Principles said that the state had the right to change the Afghan economy from an economy where man was exploited to an economy where man was free. Another clause stated that the state had the right to take "families, both parents and children, under its supervision." While it looked democratic at the outset, the Fundamental Principles was based on contradictions. The Fundamental Principles led to the establishment of two important state organs: the Special Revolutionary Court, a specialized court for crimes against national security and territorial integrity, and the Institute for Legal and Scientific Research and Legislative Affairs, the supreme legislative organ of state, This body could amend and draft laws, and introduce regulations and decrees on behalf of the government. The introduction of more Soviet-style institutions led the Afghan people to distrust the communist government even more. The Fundamental Principles constitution came into power on 22 April 1980. Dividing power: Khalq–Parcham With Karmal's ascension to power, Parchamites began to "settle old scores". Revolutionary Troikas were created to arrest, sentence and execute people. Amin's guard were the first victims of the terror which ensued. Those commanders who had stayed loyal to Amin were arrested, filling the prisons. The Soviets protested, and Karmal replied, "As long as you keep my hands bound and do not let me deal with the Khalq faction there will be no unity in the PDPA and the government cannot become strong ... They tortured and killed us. They still hate us! They are the enemies of the party ..." Amin's daughter, along with her baby, was imprisoned for twelve years, until Mohammad Najibullah, then leader of the PDPA, released her. When Karmal took power, leading posts in the Party and Government bureaucracy were taken over by Parchamites. The Khalq faction was removed from power, and only technocrats, opportunists and individuals which the Soviets trusted would be appointed to the higher echelons of government. Khalqists remained in control of the Ministry of Interior, but Parchamites were given control over KHAD and the secret police. The Parchamites and the Khalqists controlled an equal share of the military. Two out of Karmal's three Council of Ministers deputy chairmen were Khalqists. Khalqists controlled the Ministry of Communications and the interior ministry. Parchamites, on the other hand, controlled the Ministry of Foreign Affairs and the Ministry of Defence. In addition to the changes in government, the Parchamites held clear majority in the PDPA Central Committee. Only one Khalqi, Saleh Mohammad Zeary, was a member of the PDPA Secretariat during Karmal's rule. Over 14 and 15 March 1982 the PDPA held a party conference at the Kabul Polytechnic Institute instead of a party congress, since a party congress would have given the Khalq faction a majority and could have led to a Khalqist takeover of the PDPA. The rules of holding a party conference were different, and the Parchamites had a three-fifths majority. This infuriated several Khalqists; the threat of expulsion did not lessen their anger. The conference was not successful, but it was portrayed as such by the official media. The conference broke up after one and a half days of a 3-day long program, because of the inter-party struggle for power between the Khalqists and the Parchamites. A "program of action" was introduced, and party rules were given minor changes. As an explanation of the low party membership, the official media also made it seem hard to become a member of the party. PDPA base When Karmal took power, he began expanding the support base of the PDPA. Karmal tried to persuade certain groups, which had been referred to class enemies of the revolution during Taraki and Amin's rule, to support the PDPA. Karmal appointed several non-communists to top positions. Between March and May 1980, 78 out of the 191 people appointed to government posts were not members of the PDPA. Karmal reintroduced the old Afghan custom of having an Islamic invocation every time the government issued a proclamation. In his first live speech to the Afghan people, Karmal called for the establishment of the National Fatherland Front (NFF); the NFF's founding congress was held in June 1981. Unfortunately for Karmal, his policies did not lead to a notable increase in support for his regime, and it did not help Karmal that most Afghans saw the Soviet intervention as an invasion. By 1981, the government gave up on political solutions to the conflict. At the fifth PDPA Central Committee plenum in June, Karmal resigned from his Council of Ministers chairmanship and was replaced by Sultan Ali Keshtmand, while Nur Ahmad Nur was given a bigger role in the Revolutionary Council. This was seen as "base broadening". The previous weight given to non-PDPA members in top positions ceased to be an important matter in the media by June 1981. This was significant, considering that up to five members of the Revolutionary Council were non-PDPA members. By the end of 1981, the previous contenders, who had been heavily presented in the media, were all gone; two were given ambassadorships, two ceased to be active in politics, and one continued as an advisor to the government. The other three changed sides, and began to work for the opposition. The national policy of reconciliation continued: in January 1984 the land reform introduced by Taraki and Amin was drastically modified, the limits of landholdings were increased to win the support of middle class peasants, the literacy programme was continued, and concessions to women were made. In 1985 the Loya Jirga was reconvened. The 1985 Loya Jirga was followed by a tribal jirga in September. In 1986 Abdul Rahim Hatef, a non-PDPA member, was elected to the NFF chairmanship. During the 1985–86 elections it was said that 60 percent of the elected officials were non-PDPA members. By the end of Karmal's rule, several non-PDPA members had high-level government positions. Civil war and military In March 1979, the military budget was 6.4 million US$, which was 8.3 percent of the government budget, but only 2.2 of gross national product. After the Soviet intervention, the defence budget increased to 208 million US$ in 1980, and 325 million US$ by 1981. In 1982 it was reported that the government spent around 22 percent of total expenditure. When the political solution failed (see "PDPA base" section), the Afghan government and the Soviet military decided to solve the conflict militarily. The change from a political to a military solution did not come suddenly. It began in January 1981, as Karmal doubled wages for military personnel, issued several promotions, and decorated one general and thirteen colonels. The draft age was lowered, the obligatory length of arms duty was extended and the age for reservists was increased to thirty-five years of age. In June 1981, Assadullah Sarwari lost his seat in the PDPA Politburo, replaced by Mohammad Aslam Watanjar, a former tank commander and Minister of Communications, Major General Mohammad Rafi was made Minister of Defence and Mohammad Najibullah appointed KHAD Chairman. These measures were introduced due to the collapse of the army during the Soviet intervention. Before the intervention the army could field 100,000 troops, after the intervention only 25,000. Desertions were pandemic, and the recruitment campaigns for young people often drove them to the opposition. To better organize the military, seven military zones were established, each with its own Defence Council. The Defence Councils were established at the national, provincial and district level to empower the local PDPA. It is estimated that the Afghan government spent as much as 40 percent of government revenue on defense. Karmal refused to recognize the rebels as genuine, saying in an interview: Economy During the civil war and the ensuing Soviet–Afghan War, most of the country's infrastructure was destroyed. Normal patterns of economic activity were disrupted. The Gross national product (GNP) fell substantially during Karmal's rule because of the conflict; trade and transport was disrupted with loss of labor and capital. In 1981 the Afghan GDP stood at 154.3 billion Afghan afghanis, a drop from 159.7 billion in 1978. GNP per capita decreased from 7,370 in 1978 to 6,852 in 1981. The dominant form of economic activity was in the agricultural sector. Agriculture accounted for 63 percent of gross domestic product (GDP) in 1981; 56 percent of the labor force was working in agriculture in 1982. Industry accounted for 21 percent of GDP in 1982, and employed 10 percent of the labor force. All industrial enterprises were government-owned. The service sector, the smallest of the three, accounted for 10 percent of GDP in 1981, and employed an estimated one-third of the labour force. The balance of payments, which had grown in the pre-communist administration of Muhammad Daoud Khan, decreased, turning negative by 1982 at 70.3 million $US. The only economic activity which grew substantially during Karmal's rule was export and import. Foreign policy Karmal observed in early 1983 that without Soviet intervention, "It is unknown what the destiny of the Afghan Revolution would be ... We are realists and we clearly realize that in store for us yet lie trials and deprivations, losses and difficulties." Two weeks before this statement Sultan Ali Keshtmand, the Chairman of the Council of Ministers, lamented the fact that half the schools and three-quarters of communications had been destroyed since 1979. The Soviet Union rejected several Western-made peace plans, such as the Carrington Plan, since they did not take into consideration the PDPA government. Most Western peace plans had been made in collaboration with the Afghan opposition forces. At the 26th Congress of the Communist Party of the Soviet Union (CPSU) Leonid Brezhnev, the General Secretary of the CPSU Central Committee, stated; The stance of the Pakistani government was clear, demanding complete Soviet withdrawal from Afghanistan and the establishment of a non-PDPA government. Karmal, summarizing his discussions with Iran and Pakistan, said "Iran and Pakistan have so far not opted for concrete and constructive positions." During Karmal's rule Afghan–Pakistani relations remained hostile; the Soviet intervention in Afghanistan was the catalyst for the hostile relationship. The increasing numbers of Afghan refugees in Pakistan challenged the PDPA's legitimacy to rule. The Soviet Union threatened in 1985 that it would support the Baloch separatist movement in Pakistan if the Pakistani government continued to aid the Afghan mujahideen. Karmal, problematically for the Soviets, did not want a Soviet withdrawal, and he hampered attempts to improve relations with Pakistan since the Pakistani government had refused to recognise the PDPA government. Public image Because Karmal was put into power without a formal ceremony as in Afghan tradition, he was seen as an illegitimate leader in many eyes of his people. A poor performance in foreign interviews also didn't help his public image where he was noted to speak like an "exhibitionist" rather than a statesman. Karmal was widely viewed as a puppet leader of the Soviet Union by Afghans and the Western press. Despite his position, Karmal was apparently not permitted to make key decisions as he was following advice from Soviet advisers. The Soviet control of the Afghan state was apparently so much that Karmal himself admitted to a friend of his unfree life, telling him: “The Soviet comrades love me boundlessly, and for the sake of my personal safety, they don’t obey even my own orders.” Fall from power and succession Mikhail Gorbachev, then General Secretary of the Central Committee of the Communist Party of the Soviet Union, said, "The main reason that there has been no national consolidation so far is that Comrade Karmal is hoping to continue sitting in Kabul with our help." Karmal's position became less secure when the Soviet leadership began blaming him for the failures in Afghanistan. Gorbachev, worried over the situation, told the Soviet Politburo "If we don't change approaches [to evacuate Afghanistan], we will be fighting there for another 20 or 30 years." It is not clear when the Soviet leadership began to campaign for Karmal's dismissal, but Andrei Gromyko discussed the possibility of Karmal's resignation with Javier Pérez de Cuéllar, the Secretary-General of the United Nations in 1982. While it was Gorbachev who would dismiss Karmal, there may have been a consensus within the Soviet leadership in 1983 that Karmal should resign. Gorbachev's own plan was to replace Karmal with Mohammad Najibullah, who had joined the PDPA at its creation. Najibullah was thought highly of by Yuri Andropov, Boris Ponomarev and Dmitriy Ustinov, and negotiations for his succession may have started in 1983. Najibullah was not the Soviet leadership's only choice for Karmal's succession; a GRU report noted that the majority of the PDPA leadership would support Assadullah Sarwari's ascension to leadership. According to the GRU, Sarwari was a better candidate as he could balance between the Pashtuns, Tajiks and Uzbeks; Najibullah was a Pashtun nationalist. Another viable candidate was Abdul Qadir, who had been a participant in the Saur Revolution. Najibullah was appointed to the PDPA Secretariat in November 1985. During Karmal's March 1986 visit to the Soviet Union, the Soviets tried to persuade Karmal that he was too ill to govern, and that he should resign. This backfired, as a Soviet doctor attending to Karmal told him he was in good health. Karmal asked to return home to Kabul, and said that he understood and would listen to the Soviet recommendations. Before leaving, Karmal promised he would step down as PDPA General Secretary. The Soviets did not trust him and sent Vladimir Kryuchkov, the head of intelligence (FCD) in the KGB, into Afghanistan. At a meeting in Kabul, Karmal confessed his undying love for the Soviet Union, comparing his ardor to his Muslim faith. Kryuchkov, concluding that he could not persuade Karmal to resign, left the meeting. After Kryuchkov left the room, the Afghan defence minister and the state security minister visited Karmal's office, telling him that he had to resign from one of his posts. Understanding that his Soviet support had been eliminated, Karmal resigned from the office of the General Secretary at the 18th PDPA Central Committee plenum. He was succeeded in his post by Najibullah. Karmal still had support within the party, and used his base to curb Najibullah's powers. He began spreading rumors that he would be reappointed General Secretary. Najibullah's power base was in the KHAD, the Afghan equivalent to the KGB, and not the party. Considering the fact that the Soviet Union had supported Karmal for over six years, the Soviet leadership wanted to ease him out of power gradually. Yuli Vorontsov, the Soviet ambassador to Afghanistan, told Najibullah to begin undermining Karmal's power slowly. Najibullah complained to the Soviet leadership that Karmal used most of his spare time looking for errors and "speaking against the National Reconciliation [programme]". At a meeting of the Soviet Politburo on 13 November 1986 it was decided that Najibullah should remove Karmal; this motion was supported by Gromyko, Vorontsov, Eduard Shevardnadze, Anatoly Dobrynin and Viktor Chebrikov. A PDPA meeting in November relieved Karmal of his Revolutionary Council chairmanship, and exiled him to Moscow where he was given a state-owned apartment and a dacha. Karmal was succeeded as Revolutionary Council chairman by Haji Mohammad Chamkani, who was not a member of the PDPA. Later life and death Many years after the end of his leadership, he denounced the Saur Revolution of 1978 in which he took part, taking aim at the Khalq governments of Taraki and Amin. He told a Soviet reporter: It was the greatest crime against the people of Afghanistan. Parcham's leaders were against armed actions because the country was not ready for a revolution... I knew that people would not support us if we decided to keep power without such support. For unknown reasons, Karmal was invited back to Kabul by Najibullah, and "for equally obscure reasons Karmal accepted", returning on 20 June 1991. (this could have been on the recommendation of Anahita Ratebzad who was very close to Karmal and also respected by Najibullah). If Najibullah's plan was to strengthen his position within the Watan Party (the renamed PDPA) by appeasing the pro-Karmal Parchamites, he failed – Karmal's apartment became a center for opposition to Najibullah's government. When Najibullah was toppled in 1992, Karmal became the most powerful politician in Kabul through leadership of the Parcham. However, his negotiations with the rebels collapsed quickly, and on 16 April 1992 the rebels, led by Gulbuddin Hekmatyar, took Kabul. After the fall of Najibullah's government, Karmal was based in Hairatan. There, it is alleged, Karmal used most of his time either trying to establish a new party, or advising people to join the secular National Islamic Movement (Junbish-i-Milli). Abdul Rashid Dostum, the leader of Junbish-i-Milli, was a supporter of Karmal during his rule. It is unknown how much control Karmal had over Dostum, but there is little evidence that Karmal was in any commanding position. Karmal's influence over Dostum appeared indirect – some of his former associates supported Dostum. Those who spoke with Karmal during this period noted his lack of interest in politics. In June 1992 it was reported that he had died in a plane crash along with Dostum, although these reports later proved to be false. In early December 1996, Karmal died in Moscow's Central Clinical Hospital from liver cancer. The date of his death was reported by some sources as 1 December and by others as 3 December. The Taliban summed up his rule as follows: [he] committed all kinds of crimes during his illegitimate rule ... God inflicted on him various kinds of hardship and pain. Eventually he died of cancer in a hospital belonging to his paymasters, the Russians.

Boone is a town in and the county seat of Watauga County, North Carolina, United States. Located in the Blue Ridge Mountains of western North Carolina, Boone is the home of Appalachian State University and the headquarters for the disaster and medical relief organization Samaritan's Purse. The population was 17,122 at the 2010 census. The town is named for famous American pioneer and explorer Daniel Boone, and every summer, other than 2020, from 1952 has hosted an outdoor amphitheatre drama, Horn in the West, portraying the British settlement of the area during the American Revolutionary War and featuring the contributions of its namesake. It is the largest community and the economic hub of the seven-county region of Western North Carolina known as the High Country. History Boone took its name from the famous pioneer and explorer Daniel Boone, who on several occasions camped at a site generally agreed to be within the present city limits. Daniel's nephews, Jesse and Jonathan (sons of brother Israel Boone), were members of the town's first church, Three Forks Baptist, still in existence today. Boone was served by the narrow gauge East Tennessee and Western North Carolina Railroad (nicknamed "Tweetsie") until the flood of 1940. The flood washed away much of the tracks and it was decided not to replace them. Boone is the home of Appalachian State University, a constituent member of the University of North Carolina. Appalachian State is the sixth-largest university in the seventeen-campus system. Caldwell Community College & Technical Institute also operates a satellite campus in Boone. "Horn in the West" is a dramatization of the life and times of the early settlers of the mountain area. It features Daniel Boone as one of its characters, and has been performed in an outdoor amphitheater near the town every summer since 1952, except for when COVID-19 necessitated canceling the 2020 performances. The original actor in the role of "Daniel Boone" was Ned Austin. His "Hollywood Star" stands on a pedestal on King Street in downtown Boone. He was followed in the role by Glenn Causey, who portrayed the rugged frontiersman for 41 years, and whose image is still seen in many of the depictions of Boone featured in the area today. Boone is notable for being home to the Junaluska community. Located in the hills just north of Downtown Boone, a free black community has existed in the area since before the Civil War. Although integration in the mid-20th century led to many of the businesses in the neighborhood closing in favor of their downtown counterparts, descendants of the original inhabitants still live in the neighborhood. Junaluska is also home to one of the few majority-African American Mennonite Brethren congregations. Boone is a center for bluegrass musicians and Appalachian storytellers. Notable artists associated with Boone include the late Grammy Award-winning bluegrass guitar player Doc Watson, and the late guitarist Michael Houser, one of the founding members of and the lead guitarist for the band Widespread Panic, as well as Old Crow Medicine Show, The Blue Rags, and Eric Church, all who are Boone natives. The Blair Farm, Daniel Boone Hotel, Jones House, John Smith Miller House, and US Post Office-Boone are listed on the National Register of Historic Places. Geography and climate Boone is located at (36.211364, −81.668657) and has an elevation of 3,333 feet (1015.9 m) above sea level. An earlier survey gave the elevation as 3,332 ft and since then it has been published as having an elevation of 3,333 ft (1,016 m). Boone has the highest elevation of any town of its size (over 10,000 population) east of the Mississippi River. As such, Boone features, depending on the isotherm used, a humid continental climate (Köppen Dfb), a rarity for the Southeastern United States, bordering on a subtropical highland climate (Cfb) and straddles the boundary between USDA Plant Hardiness Zones 6B and 7A; the elevation also results in enhanced precipitation, with of average annual precipitation. Compared to the lower elevations of the Carolinas, winters are long and cold, with frequent sleet and snowfall. The daily average temperature in January is , which gives Boone a winter climate more similar to coastal southern New England rather than the Southeast, where a humid subtropical climate (Cfa) predominates. Blizzard-like conditions are not unusual during many winters. Summers are warm, but far cooler and less humid than lower regions to the south and east, with a July daily average temperature of . Boone typically receives on average nearly of snowfall annually, far higher than the lowland areas in the rest of North Carolina. On January 21, 1985, the temperature fell to . Demographics 2020 census As of the 2020 United States census, there were 19,092 people, 5,905 households, and 1,641 families residing in the town. 2000 census As of the census of 2000, there were 13,472 people, 4,374 households, and 1,237 families residing in the town. The population density was 2,307.0 people per square mile (890.7/km). There were 4,748 housing units at an average density of 813.0 per square mile (313.9/km).

There were 4,374 households, out of which 9.6% had children under the age of 18 living with them, 21.0% were married couples living together, 5.6% had a female householder with no husband present, and 71.7% were non-families. 38.4% of all households were made up of individuals, and 7.3% had someone living alone who was 65 years of age or older. The average household size was 1.97 and the average family size was 2.63. In the town, the population was spread out, with 5.8% under 18, 65.9% from 18 to 24, 12.1% from 25 to 44, 9.1% from 45 to 64, and 7.1% who were 65 or older. The median age was 21 years. For every 100 females, there are 95.6 males. For every 100 females age 18 and over, there were 94.7 males. The median income for a household in the town was $20,541, and the median income for a family was $49,762. The per capita income was $12,256. Males had a median income of $28,060 versus $20,000 for females. About 9.2% of families and 37.0% of the population were below the poverty line, including 6.3% of those under the age of 18 and 9.1% of those 65 and older. Media Newspaper Boone is mainly served by three local newspapers: The Watauga Democrat is published on Wednesdays and Sundays. The Mountain Times (free weekly entertainment publication). The High Country Press (daily online news publication). A smaller newspaper, The Appalachian, is Appalachian State University's campus newspaper; it is published once a week on Thursdays. In addition to the locally printed papers, a monthly entertainment pamphlet named Kraut Creek Revival has limited circulation and is funded by a Denver, NC-based newspaper.

Development Industrial, commercial, and residential development in the town of Boone is a controversial issue due to its location in the mountains of Appalachia. On October 16, 2009, the town council accepted the "Boone 2030 Land Use Plan." While the document itself is not in any way actual law, it is used by the town council, board of adjustment, and other committees to guide decision making as to what types of development are appropriate. In 2009, the North Carolina Department of Transportation began widening 1.1 miles of U.S. 421 (King Street) to a 4-to-6-lane divided highway with a raised concrete median from U.S. 321 (Hardin Street) to east of N.C. 194 (Jefferson Road), including a new entrance and exit to the new Watauga High School, at a cost of $16.2 million. The widening has displaced 25 businesses and 63 residences east of historic downtown King Street. The project was slated to be completed by December 31, 2011, but construction continued into the spring of 2012. Sports Boone is home to the Appalachian State Mountaineers as well as Appalachian FC.

Bambara (Arabic script: ), also known as Bamana (N'Ko script: ) or Bamanankan (), is a lingua franca and national language of Mali spoken by perhaps 15 million people, natively by 5 million Bambara people and about 10 million second-language users. It is estimated that about 80 percent of the population of Mali speak Bambara as a first or second language. It has a subject–object–verb clause structure and two lexical tones. The native name bamanankan means "the language () of greats (), people who reject the religion of Islam", as opposed to speakers of Dyula, who are Muslim. Classification Bamana is a variety of a group of closely related languages called Manding, whose native speakers trace their cultural history to the medieval Mali Empire. Varieties of Manding are generally considered (among native speakers) to be mutually intelligible – dependent on exposure or familiarity with dialects between speakers – and spoken by 30 to 40 million people in the countries Burkina Faso, Senegal, Guinea-Bissau, Guinea, Liberia, Ivory Coast and the Gambia. Manding is part of the larger Mandé family of languages. Geographical distribution Bambara is spoken throughout Mali as a lingua franca. The language is most widely spoken in the areas east, south, and north of Bamako, where native speakers and/or those that identify as members of the Bambara ethnic group are most densely populated. These regions are also usually considered to be the historical geographical origin of Bambara people, particularly Ségou, after diverging from other Manding groups. Dialects The main dialect is Standard Bamara, which has significant influence from Maninkakan. Bambara has many local dialects: Kaarta, Tambacounda (west); Beledugu, Bananba, Mesekele (north); Jitumu, Jamaladugu, Segu (center); Cakadugu, Keleyadugu, Jalakadougu, Kurulamini, Banimɔncɛ, Cɛmala, Cɛndugu, Baninkɔ, Shɛndugu, Ganadugu (south); Kala, Kuruma, Saro, dialects to the northeast of Mopti (especially Bɔrɛ); Zegedugu, Bɛndugu, Bakɔkan, Jɔnka (southeast)., Writing Since 1967, Bambara has mostly been written in the Latin script, using some additional phonetic characters. The vowels are a, e, ɛ (formerly è), i, o, ɔ (formerly ò), u; accents can be used to indicate tonality. The former digraph ny is now written ɲ when it designates a palatal nasal glide; the ny spelling is kept for the combination of a nasal vowel with a subsequent oral palatal glide. Following the 1966 Bamako spelling conventions, a nasal velar glide "ŋ" is written as "ŋ", although in early publications it was often transcribed as ng or nk. The N'Ko () alphabet is a script devised by Solomana Kante in 1949 as a writing system for the Manding languages of West Africa; N’Ko means 'I say' in all Manding languages. Kante created N’Ko in response to what he felt were beliefs that Africans were a "cultureless people" since prior to this time there had been no indigenous African writing system for his language. N'ko first gained a strong user base around the Maninka-speaking area of Kante's hometown of Kankan, Guinea and disseminated from there into other Manding-speaking parts of West Africa. N'ko and the Arabic script are still in use for Bambara, although only the Latin-based orthography is officially recognized in Mali. Additionally, a script known as Masaba or Ma-sa-ba was developed for the language beginning in 1930 by Woyo Couloubayi (c.1910-1982) of Assatiémala. Named for the first characters in Couloubayi's preferred collation order, Masaba is a syllabary which uses diacritics to indicate vowel qualities such as tone, length, and nasalization. Though not conclusively related to other writing systems, Masaba appears to draw on traditional Bambara iconography and shares some similarities with the Vai syllabary of Liberia and with Arabic-derived secret alphabets used in Hodh (now Hodh El Gharbi and Hodh Ech Chargui Regions of Mauritania). As of 1978, Masaba was in limited use in several communities in Nioro Cercle for accounting, personal correspondence, and the recording of Muslim prayers; the script's current status and prevalence is unknown. Latin orthography It uses seven vowels a, e, ɛ, i, o, ɔ and u, each of which can be nasalized, pharyngealized and murmured, giving a total number of 21 vowels (the letters approximate their IPA equivalents). Writing with the Latin alphabet began during the French colonization, and the first orthography was introduced in 1967. Literacy is limited, especially in rural areas. Although written literature is only slowly evolving (due to the predominance of French as the "language of the educated"), there exists a wealth of oral literature, which is often tales of kings and heroes. This oral literature is mainly tradited by the griots (Jeliw in Bambara) who are a mixture of storytellers, praise singers, and human history books who have studied the trade of singing and reciting for many years. Many of their songs are very old and are said to date back to the old empire of Mali.

"S" is pronounced most often as in the English word "see" but is sometimes pronounced as "sh" [ʃ] as in the word "shoe" or as [z]. "G" is pronounced most often as in the English word "go" but in the middle of a word, it can be pronounced as in the Spanish word "abogado" ([ɣ]) and sometimes at the beginning of a word as [gw]. Vowels Grammar Bambara is an agglutinative language, meaning that morphemes are glued together to form a word. The basic sentence structure is Subject Object Verb. Take the phrase, "n t'a lon" (I don't know [it]). "n" is the subject (I), "a" is the object (it), and "[ta] lon" is the verb ([to] know). The "t" is from the present tense marker "té." "té" is the negative present tense marker and "bé" is the affirmative present tense marker. Therefore, "n b'a don" would mean "I know it". Bambara is an SOV language and has two (mid/standard and high) tones; e.g. sa 'die' vs. sá 'snake.' The typical argument structure of the language consists of a subject, followed by an aspectival auxiliary, followed by the direct object, and finally a transitive verb. Naturally, if the verb is intransitive, the direct object is absent. Bambara does not inflect for gender. Gender for a noun can be specified by adding an adjective, -cɛ or -kɛ for male and -muso for female. The plural is formed by attaching a vocalic suffix -u, most often with a low tone (in the orthography, -w) to nouns or adjectives. Bambara uses postpositions in much the same manner as languages like English and French use prepositions. These postpositions are found after the noun and are used to express direction, location, and in some cases, possession. Loan words In urban areas, many Bamanankan conjunctions have been replaced in everyday use by French borrowings that often mark code-switches. The Bamako dialect makes use of sentences like: N taara Kita mais il n'y avait personne là-bas. : I went to Kita [Bamanankan ] but there was no one there [French]. The sentence in Bamanankan alone would be Ń taara Kita nka mɔkɔ si tun tɛ yen. The French proposition "est-ce que" is also used in Bamanankan ; however, it is pronounced more slowly and as three syllables, . Bamanankan uses many French loan words. For example, some people might say: I ka kurusi ye jauni ye: "Your skirt is yellow" (using a derivation of the French word for yellow, jaune.) However, one could also say: I ka kulosi ye nɛrɛmukuman ye, also meaning "your skirt is yellow." The original Bamanankan word for yellow comes from "nɛrɛmuku," being flour (muku) made from néré (locust bean), a seed from a long seed pod. Nɛrɛmuku is often used in sauces in Southern Mali. Most French loan words are suffixed with the sound 'i'; this is particularly common when using French words which have a meaning not traditionally found in Mali. For example, the Bamanankan word for snow is niegei, based on the French word for snow neige. As there has never been snow in Mali, there was no unique word in Bamanankan to describe it. Examples Music Malian artists such as Oumou Sangaré, Sidiki Diabaté, Fatoumata Diawara, Rokia Traoré, Ali Farka Touré, Habib Koité and the married duo Amadou & Mariam often sing in Bambara. Lyrics in Bambara occur on Stevie Wonder's Journey Through "The Secret Life of Plants". Additionally, in 2010, Spanish rock group Dover released its 7th studio album I Ka Kené with the majority of lyrics in the language. American rapper Nas also released a track titled "Sabali" in 2010, which featured Damian Marley. Sabali is a Bambara word that means patience. Legal status Bambara is one of several languages designated by Mali as a national language. References Citation Sources Bailleul Ch. Dictionnaire Bambara-Français. 3e édition corrigée.

The Bronze Age is a historic period, approximately 3300 BCE to 1200 BCE, that was characterized by the use of bronze, in some areas proto-writing, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age Stone-Bronze-Iron system, as proposed in 1836 by Christian Jürgensen Thomsen, for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze was harder and more durable than other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, its high melting point of placed it out of reach of common use until the end of the second millennium BCE. Tin's low melting point of and copper's relatively moderate melting point of placed them within the capabilities of the Neolithic pottery kilns, which date back to 6,000 BC and were able to produce temperatures greater than . Copper and tin ores are rare, since there were no tin bronzes in Western Asia before trading in bronze began in the 3rd millennium BCE. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition. Bronze Age cultures differed in their development of writing. According to archaeological evidence, cultures in Mesopotamia (cuneiform script) and Egypt (hieroglyphs) developed the earliest practical writing systems. History The overall period is characterized by the widespread use of bronze, though the place and time of the introduction and development of bronze technology were not universally synchronous. Human-made tin bronze technology requires set production techniques. Tin must be mined (mainly as the tin ore cassiterite) and smelted separately, then added to hot copper to make bronze alloy. The Bronze Age was a time of extensive use of metals and of developing trade networks (See Tin sources and trade in ancient times). A 2013 report suggests that the earliest tin-alloy bronze dates to the mid-5th millennium BCE in a Vinča culture site in Pločnik (Serbia), although this culture is not conventionally considered part of the Bronze Age. The dating of the foil has been disputed. Near East Western Asia and the Near East were the first regions to enter the Bronze Age, which began with the rise of the Mesopotamian civilization of Sumer in the mid-4th millennium BCE. Cultures in the ancient Near East (often called one of "the cradles of civilization") practiced intensive year-round agriculture, developed writing systems, invented the potter's wheel, created centralized governments (usually in form of hereditary monarchies), written law codes, city-states and nation-states and empires, embarked on advanced architectural projects, introduced social stratification, economic and civil administration, slavery, and practiced organized warfare, medicine and religion. Societies in the region laid the foundations for astronomy, mathematics and astrology. Dates are approximate, consult particular article for details Anatolia The Hittite Empire was established in Hattusa in northern Anatolia from the 18th century BCE. In the 14th century BCE the Hittite Kingdom was at its height, encompassing central Anatolia, southwestern Syria as far as Ugarit, and upper Mesopotamia. After 1180 BCE, amid general turmoil in the Levant conjectured to have been associated with the sudden arrival of the Sea Peoples, the kingdom disintegrated into several independent "Neo-Hittite" city-states, some of which survived until as late as the 8th century BCE. Arzawa in Western Anatolia during the second half of the second millennium BCE likely extended along southern Anatolia in a belt that reaches from near the Turkish Lakes Region to the Aegean coast. Arzawa was the western neighbor—sometimes a rival and sometimes a vassal—of the Middle and New Hittite Kingdoms. The Assuwa league was a confederation of states in western Anatolia that was defeated by the Hittites under an earlier Tudhaliya I, around 1400 BCE. Arzawa has been associated with the much more obscure Assuwa generally located to its north. It probably bordered it, and may even be an alternative term for it (at least during some periods). Egypt Early Bronze dynasties In Ancient Egypt, the Bronze Age begins in the Protodynastic period, 3150 BCE. The archaic Early Bronze Age of Egypt, known as the Early Dynastic Period of Egypt, immediately follows the unification of Lower and Upper Egypt, 3100 BCE. It is generally taken to include the First and Second Dynasties, lasting from the Protodynastic Period of Egypt until about 2686 BCE, or the beginning of the Old Kingdom. With the First Dynasty, the capital moved from Abydos to Memphis with a unified Egypt ruled by an Egyptian god-king. Abydos remained the major holy land in the south. The hallmarks of ancient Egyptian civilization, such as art, architecture and many aspects of religion, took shape during the Early Dynastic Period. Memphis in the Early Bronze Age was the largest city of the time. The Old Kingdom of the regional Bronze Age is the name given to the period in the 3rd millennium BCE when Egypt attained its first continuous peak of civilization in complexity and achievement – the first of three "Kingdom" periods, which mark the high points of civilization in the lower Nile Valley (the others being Middle Kingdom and the New Kingdom). The First Intermediate Period of Egypt, often described as a "dark period" in ancient Egyptian history, spanned about 100 years after the end of the Old Kingdom from about 2181 to 2055 BCE. Very little monumental evidence survives from this period, especially from the early part of it. The First Intermediate Period was a dynamic time when the rule of Egypt was roughly divided between two competing for power bases: Heracleopolis in Lower Egypt and Thebes in Upper Egypt. These two kingdoms would eventually come into conflict, with the Theban kings conquering the north, resulting in the reunification of Egypt under a single ruler during the second part of the 11th Dynasty. Nubia The Bronze Age in Nubia started as early as 2300 BCE. Copper smelting was introduced by Egyptians to the Nubian city of Meroë, in modern-day Sudan, around 2600 BCE. A furnace for bronze casting has been found in Kerma that is dated to 2300–1900 BCE. Middle Bronze dynasties The Middle Kingdom of Egypt lasted from 2055 to 1650 BCE. During this period, the Osiris funerary cult rose to dominate Egyptian popular religion. The period comprises two phases: the 11th Dynasty, which ruled from Thebes and the 12th and 13th Dynasties centered on el-Lisht. The unified kingdom was previously considered to comprise the 11th and 12th Dynasties, but historians now at least partially consider the 13th Dynasty to belong to the Middle Kingdom. During the Second Intermediate Period, Ancient Egypt fell into disarray for a second time, between the end of the Middle Kingdom and the start of the New Kingdom. It is best known for the Hyksos, whose reign comprised the 15th and 16th dynasties. The Hyksos first appeared in Egypt during the 11th Dynasty, began their climb to power in the 13th Dynasty, and emerged from the Second Intermediate Period in control of Avaris and the Delta. By the 15th Dynasty, they ruled lower Egypt, and they were expelled at the end of the 17th Dynasty. Late Bronze dynasties The New Kingdom of Egypt, also referred to as the Egyptian Empire, lasted from the 16th to the 11th century BCE. The New Kingdom followed the Second Intermediate Period and was succeeded by the Third Intermediate Period. It was Egypt's most prosperous time and marked the peak of Egypt's power. The later New Kingdom, i.e. the 19th and 20th Dynasties (1292–1069 BCE), is also known as the Ramesside period, after the eleven pharaohs that took the name of Ramesses. Iranian Plateau Elam was a pre-Iranian ancient civilization located to the east of Mesopotamia. In the Old Elamite period (Middle Bronze Age), Elam consisted of kingdoms on the Iranian Plateau, centered in Anshan, and from the mid-2nd millennium BCE, it was centered in Susa in the Khuzestan lowlands. Its culture played a crucial role in the Gutian Empire and especially during the Iranian Achaemenid dynasty that succeeded it. The Oxus civilization was a Bronze Age Central Asian culture dated to 2300–1700 BCE and centered on the upper Amu Darya (Oxus). In the Early Bronze Age, the culture of the Kopet Dag oases and Altyndepe developed a proto-urban society. This corresponds to level IV at Namazga-Tepe. Altyndepe was a major center even then. Pottery was wheel-turned. Grapes were grown. The height of this urban development was reached in the Middle Bronze Age 2300 BCE, corresponding to level V at Namazga-Depe. This Bronze Age culture is called the Bactria–Margiana Archaeological Complex (BMAC). The Kulli culture, similar to those of the Indus Valley Civilisation, was located in southern Balochistan (Gedrosia) 2500–2000 BCE. Agriculture was the economic base of these people. At several places, dams were found, providing evidence for a highly developed water management system. Konar Sandal is associated with the hypothesized "Jiroft culture", a 3rd-millennium-BC culture postulated based on a collection of artifacts confiscated in 2001. Levant In modern scholarship, the chronology of the Bronze Age Levant is divided into Early/Proto Syrian; corresponding to the Early Bronze. Old Syrian; corresponding to the Middle Bronze. Middle Syrian; corresponding to the Late Bronze. The term Neo-Syria is used to designate the early Iron Age. The old Syrian period was dominated by the Eblaite first kingdom, Nagar and the Mariote second kingdom. The Akkadians conquered large areas of the Levant and were followed by the Amorite kingdoms, 2000–1600 BCE, which arose in Mari, Yamhad, Qatna, Assyria. From the 15th century BCE onward, the term Amurru is usually applied to the region extending north of Canaan as far as Kadesh on the Orontes River. The earliest-known Ugaritic contact with Egypt (and the first exact dating of Ugaritic civilization) comes from a carnelian bead identified with the Middle Kingdom pharaoh Senusret I, 1971–1926 BCE. A stela and a statuette from the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear at what time these monuments got to Ugarit. In the Amarna letters, messages from Ugarit 1350 BCE written by Ammittamru I, Niqmaddu II, and his queen, were discovered. From the 16th to the 13th century BCE, Ugarit remained in constant touch with Egypt and Cyprus (named Alashiya). The Mitanni was a loosely organized state in northern Syria and south-east Anatolia from 1500–1300 BCE. Founded by an Indo-Aryan ruling class that governed a predominantly Hurrian population, Mitanni came to be a regional power after the Hittite destruction of Kassite Babylon created a power vacuum in Mesopotamia. At its beginning, Mitanni's major rival was Egypt under the Thutmosids. However, with the ascent of the Hittite empire, Mitanni and Egypt allied to protect their mutual interests from the threat of Hittite domination. At the height of its power, during the 14th century BCE, it had outposts centered on its capital, Washukanni, which archaeologists have located on the headwaters of the Khabur River. Eventually, Mitanni succumbed to Hittite, and later Assyrian attacks, and was reduced to a province of the Middle Assyrian Empire. The Israelites were an ancient Semitic-speaking people of the Ancient Near East who inhabited part of Canaan during the tribal and monarchic periods (15th to 6th centuries BCE), and lived in the region in smaller numbers after the fall of the monarchy. The name "Israel" first appears 1209 BCE, at the end of the Late Bronze Age and the very beginning of the Iron Age, on the Merneptah Stele raised by the Egyptian pharaoh Merneptah. The Aramaeans were a Northwest Semitic semi-nomadic and pastoralist people who originated in what is now modern Syria (Biblical Aram) during the Late Bronze Age and the early Iron Age. Large groups migrated to Mesopotamia, where they intermingled with the native Akkadian (Assyrian and Babylonian) population. The Aramaeans never had a unified empire; they were divided into independent kingdoms all across the Near East. After the Bronze Age collapse, their political influence was confined to many Syro-Hittite states, which were entirely absorbed into the Neo-Assyrian Empire by the 8th century BCE. Mesopotamia The Mesopotamian Bronze Age began about 3500 BCE and ended with the Kassite period ( 1500 BCE – 1155 BCE). The usual tripartite division into an Early, Middle and Late Bronze Age is not used. Instead, a division primarily based on art-historical and historical characteristics is more common. The cities of the Ancient Near East housed several tens of thousands of people. Ur, Kish, Isin, Larsa and Nippur in the Middle Bronze Age and Babylon, Calah and Assur in the Late Bronze Age similarly had large populations. The Akkadian Empire (2335–2154 BCE) became the dominant power in the region, and after its fall the Sumerians enjoyed a renaissance with the Neo-Sumerian Empire. Assyria was extant from as early as the 25th century BCE, and became a regional power with the Old Assyrian Empire ( 2025–1750 BCE). The earliest mention of Babylon (then a small administrative town) appears on a tablet from the reign of Sargon of Akkad in the 23rd century BCE. The Amorite dynasty established the city-state of Babylon in the 19th century BCE. Over 100 years later, it briefly took over the other city-states and formed the short-lived First Babylonian Empire during what is also called the Old Babylonian Period. Akkad, Assyria, and Babylonia all used the written East Semitic Akkadian language for official use and as a spoken language. By that time, the Sumerian language was no longer spoken, but was still in religious use in Assyria and Babylonia, and would remain so until the 1st century CE. The Akkadian and Sumerian traditions played a major role in later Assyrian and Babylonian culture, even though Babylonia (unlike the more militarily powerful Assyria) itself was founded by non-native Amorites and often ruled by other non-indigenous peoples, such as Kassites, Aramaeans and Chaldeans, as well as its Assyrian neighbors. Asia Central Asia Agropastoralism For many decades scholars made superficial reference to Central Asia as the "pastoral realm" or alternatively, the "nomadic world", in what researchers have come to call the "Central Asian void" - a 5000 year span that was neglected in studies of the origins of agriculture. Foothill regions and glacial melt streams supported Bronze Age agropastoralists who developed complex east-west trade routes between Central Asia and China that introduced wheat and barley to China and spread millet across Central Asia. Bactria–Margiana Archaeological Complex The Bactria–Margiana Archaeological Complex (BMAC), also known as the Oxus civilization, was a Bronze Age civilization in Central Asia, dated to c. 2400–1600 BCE, located in present-day northern Afghanistan, eastern Turkmenistan, southern Uzbekistan and western Tajikistan, centred on the upper Amu Darya (Oxus River). Its sites were discovered and named by the Soviet archaeologist Viktor Sarianidi (1976). Bactria was the Greek name for the area of Bactra (modern Balkh), in what is now northern Afghanistan, and Margiana was the Greek name for the Persian satrapy of Marguš, the capital of which was Merv, in modern-day southeastern Turkmenistan. A wealth of information indicates that the BMAC had close international relations with the Indus Valley, the Iranian Plateau, and possibly even indirectly with Mesopotamia, and all civilizations were very familiar with lost wax casting. According to recent studies the BMAC was not a primary contributor to later South-Asian genetics. Seima-Turbino Phenomenon The Altai Mountains in what is now southern Russia and central Mongolia have been identified as the point of origin of a cultural enigma termed the Seima-Turbino Phenomenon. It is conjectured that changes in climate in this region around 2000 BCE and the ensuing ecological, economic and political changes triggered a rapid and massive migration westward into northeast Europe, eastward into China and southward into Vietnam and Thailand across a frontier of some 4,000 miles. This migration took place in just five to six generations and led to peoples from Finland in the west to Thailand in the east employing the same metal working technology and, in some areas, horse breeding and riding. It is further conjectured that the same migrations spread the Uralic group of languages across Europe and Asia: some 39 languages of this group are still extant, including Hungarian, Finnish and Estonian. However, recent genetic testings of sites in south Siberia and Kazakhstan (Andronovo horizon) would rather support a spreading of the bronze technology via Indo-European migrations eastwards, as this technology was well known for quite a while in western regions. East Asia China In China, the earliest bronze artifacts have been found in the Majiayao culture site (between 3100 and 2700 BCE). The term "Bronze Age" has been transferred to the archaeology of China from that of Western Eurasia, and there is no consensus or universally used convention delimiting the "Bronze Age" in the context of Chinese prehistory. By convention, the "Early Bronze Age" in China is sometimes taken as equivalent to the "Shang dynasty" period (16th to 11th centuries BCE), and the "Later Bronze Age" as equivalent to the "Zhou dynasty" period (11th to 3rd centuries BCE, from the 5th century, also dubbed "Iron Age"), although there is an argument to be made that the "Bronze Age" proper never ended in China, as there is no recognizable transition to an "Iron Age". Significantly, together with the jade art that precedes it, bronze was seen as a "fine" material for ritual art when compared with iron or stone. Bronze metallurgy in China originated in what is referred to as the Erlitou () period, which some historians argue places it within the range of dates controlled by the Shang dynasty. Others believe the Erlitou sites belong to the preceding Xia () dynasty. The U.S. National Gallery of Art defines the Chinese Bronze Age as the "period between about 2000 BCE and 771 BCE", a period that begins with the Erlitou culture and ends abruptly with the disintegration of Western Zhou rule. While it is by far more likely that bronze work developed inside China separately from outside influence, the discovery of Europoid mummies in Xinjiang suggests a possible route of transmission from the West beginning in the early second millennium BCE. This is, however, still just speculation since there is a lack of direct evidence. A few human mummies alone cannot provide sufficient explanation of metallurgy transmission. Furthermore, the oldest bronze objects found in China so far were discovered at the Majiayao site in Gansu rather than at Xinjiang. The Shang dynasty (also known as the Yin dynasty) of the Yellow River Valley rose to power after the Xia dynasty around 1600 BCE. While some direct information about the Shang dynasty comes from Shang-era inscriptions on bronze artifacts, most comes from oracle bones—turtle shells, cattle scapulae, or other bones—which bear glyphs that form the first significant corpus of recorded Chinese characters. The production of Erlitou in Henan represents the earliest large-scale metallurgy industry in the Central Plains of China. The influence of the Saima-Turbino metalworking tradition from the north is supported by a series of recent discoveries in China of many unique perforated spearheads with downward hooks and small loops on the same or opposite side of the socket, which could be associated with the Seima-Turbino visual vocabulary of southern Siberia. The metallurgical centers of northwestern China, especially Qijia in Gansu and Kexingzhuang culture in Shaanxi, played an intermediary role in this process. Iron has been found from the Zhou dynasty, but its use was minimal. Chinese literature dating to the 6th century BCE attests knowledge of iron smelting, yet bronze continues to occupy the seat of significance in the archaeological and historical record for some time after this. Historian W.C. White argues that iron did not supplant bronze "at any period before the end of the Zhou dynasty (256 BC)" and that bronze vessels make up the majority of metal vessels through the Later Han period, or to 221 BC. The Chinese bronze artifacts generally are either utilitarian, like spear points or adze heads, or "ritual bronzes", which are more elaborate versions in precious materials of everyday vessels, as well as tools and weapons. Examples are the numerous large sacrificial tripods known as dings in Chinese; there are many other distinct shapes. Surviving identified Chinese ritual bronzes tend to be highly decorated, often with the taotie motif, which involves highly stylized animal faces. These appear in three main motif types: those of demons, of symbolic animals, and abstract symbols. Many large bronzes also bear cast inscriptions that are the great bulk of the surviving body of early Chinese writing and have helped historians and archaeologists piece together the history of China, especially during the Zhou dynasty (1046–256 BCE). The bronzes of the Western Zhou dynasty document large portions of history not found in the extant texts that were often composed by persons of varying rank and possibly even social class. Further, the medium of cast bronze lends the record they preserve a permanence not enjoyed by manuscripts. These inscriptions can commonly be subdivided into four parts: a reference to the date and place, the naming of the event commemorated, the list of gifts given to the artisan in exchange for the bronze, and a dedication. The relative points of reference these vessels provide have enabled historians to place most of the vessels within a certain time frame of the Western Zhou period, allowing them to trace the evolution of the vessels and the events they record. Korea The beginning of the Bronze Age on the peninsula is around 1000–800 BCE. Although the Korean Bronze Age culture derives from the Liaoning and Manchuria, it exhibits unique typology and styles, especially in ritual objects. The Mumun pottery period is named after the Korean name for undecorated or plain cooking and storage vessels that form a large part of the pottery assemblage over the entire length of the period, but especially 850–550 BCE. The Mumun period is known for the origins of intensive agriculture and complex societies in both the Korean Peninsula and the Japanese Archipelago. The Middle Mumun pottery period culture of the southern Korean Peninsula gradually adopted bronze production ( 700–600? BCE) after a period when Liaoning-style bronze daggers and other bronze artifacts were exchanged as far as the interior part of the Southern Peninsula ( 900–700 BCE). The bronze daggers lent prestige and authority to the personages who wielded and were buried with them in high-status megalithic burials at south-coastal centers such as the Igeum-dong site. Bronze was an important element in ceremonies and as for mortuary offerings until 100. Japan The Japanese archipelago saw the introduction of bronze during the beginning of the Early Yayoi period (≈300 BCE), which saw the introduction of metalworking and agricultural practices brought in by settlers arriving from the continent. Bronze and iron smelting techniques spread to the Japanese archipelago through contact with other ancient East Asian civilizations, particularly immigration and trade from ancient Korean peninsula and ancient mainland China. Iron was mainly used for agricultural and other tools, whereas ritual and ceremonial artifacts were mainly made of bronze. South Asia Dates are approximate, consult particular article for details Indus Valley The Bronze Age on the Indian subcontinent began around 3300 BCE with the beginning of the Indus Valley civilization. Inhabitants of the Indus Valley, the Harappans, developed new techniques in metallurgy and produced copper, bronze, lead and tin. The Late Harappan culture, which dates from 1900 to 1400 BCE, overlapped the transition from the Bronze Age to the Iron Age; thus it is difficult to date this transition accurately. It has been claimed that a 6,000-year-old copper amulet manufactured in Mehrgarh in the shape of wheel spoke is the earliest example of lost wax casting in the world. The civilization's cities were noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, clusters of large non-residential buildings, and new techniques in handicraft (carnelian products, seal carving) and metallurgy (copper, bronze, lead, and tin). The large cities of Mohenjo-daro and Harappa very likely grew to contain between 30,000 and 60,000 individuals, and the civilization itself during its florescence may have contained between one and five million individuals. Southeast Asia Thailand In Ban Chiang, Thailand, (Southeast Asia) bronze artifacts have been discovered dating to 2100 BCE. However, according to the radiocarbon dating on the human and pig bones in Ban Chiang, some scholars propose that the initial Bronze Age in Ban Chiang was in late 2nd millennium. In Nyaunggan, Burma, bronze tools have been excavated along with ceramics and stone artifacts. Dating is still currently broad (3500–500 BCE). Ban Non Wat, excavated by Charles Higham, was a rich site with over 640 graves excavated that gleaned many complex bronze items that may have had social value connected to them. Ban Chiang, however, is the most thoroughly documented site while having the clearest evidence of metallurgy when it comes to Southeast Asia. With a rough date range of late 3rd millennium BCE to the first millennium CE, this site alone has various artifacts such as burial pottery (dating from 2100 to 1700 BCE), fragments of Bronze, copper-base bangles, and much more. What's interesting about this site, however, is not just the old age of the artifacts but that this technology suggested on-site casting from the very beginning. The on-site casting supports the theory that Bronze was first introduced in Southeast Asia as fully developed which therefore shows that Bronze was innovated from a different country. Some scholars believe that the copper-based metallurgy was disseminated from northwest and central China via south and southwest areas such as Guangdong province and Yunnan province and finally into southeast Asia around 1000 BCE. Archaeology also suggests that Bronze Age metallurgy may not have been as significant a catalyst in social stratification and warfare in Southeast Asia as in other regions, social distribution shifting away from chiefdom-states to a heterarchical network. Data analyses of sites such as Ban Lum Khao, Ban Na Di, Non-Nok Tha, Khok Phanom Di, and Nong Nor have consistently led researchers to conclude that there was no entrenched hierarchy. Vietnam Dating back to the Neolithic Age, the first bronze drum, called the Dong Son drum, were uncovered in and around the Red River Delta regions of Northern Vietnam and Southern China. These relate to the prehistoric Dong Son Culture of Vietnam. Archaeological research in Northern Vietnam indicates an increase in rates of infectious disease following the advent of metallurgy; skeletal fragments in sites dating to the early and mid-Bronze Age evidence a greater proportion of lesions than in sites of earlier periods. There are a few possible implications of this. One is the increased contact with bacterial and/or fungal pathogens due to increased population density and land clearing/cultivation. The other one is decreased levels of immunocompetence in the Metal age due to changes in the diet caused by agriculture. The last is that there may have been an emergence of infectious disease in the Da But the period that evolved into a more virulent form in the metal period. Europe A few examples of named Bronze Age cultures in Europe in roughly relative order. Dates are approximate, consult particular article for details The chosen cultures overlapped in time and the indicated periods do not fully correspond to their estimated extents. Balkans A study in the journal Antiquity published in 2013 reported the discovery of a tin bronze foil from the Pločnik archaeological site securely dated to c. 4650 BCE as well as 14 other artifacts from Serbia and Bulgaria dated to before 4000 BCE has shown that early tin bronze was more common than previously thought, and developed independently in Europe 1500 years before the first tin bronze alloys in the Near East. The production of complex tin bronzes lasted for c. 500 years in the Balkans. The authors reported that evidence for the production of such complex bronzes disappears at the end of the 5th millennium coinciding with the "collapse of large cultural complexes in north-eastern Bulgaria and Thrace in the late fifth millennium BCE". Tin bronzes using cassiterite tin would be reintroduced to the area again some 1500 years later. Aegean Sea and Balkans The Aegean Bronze Age began around 3200 BCE, when civilizations first established a far-ranging trade network. This network imported tin and charcoal to Cyprus, where copper was mined and alloyed with the tin to produce bronze. Bronze objects were then exported far and wide and supported the trade. Isotopic analysis of tin in some Mediterranean bronze artifacts suggests that they may have originated from Great Britain. Knowledge of navigation was well developed at this time and reached a peak of skill not exceeded (except perhaps by Polynesian sailors) until 1730 when the invention of the chronometer enabled the precise determination of longitude. The Minoan civilization based in Knossos on the island of Crete appears to have coordinated and defended its Bronze Age trade. Ancient empires valued luxury goods in contrast to staple foods, leading to famine. Aegean collapse Bronze Age collapse theories have described aspects of the end of the Bronze Age in this region. At the end of the Bronze Age in the Aegean region, the Mycenaean administration of the regional trade empire followed the decline of Minoan primacy. Several Minoan client states lost much of their population to famine and/or pestilence. This would indicate that the trade network may have failed, preventing the trade that would previously have relieved such famines and prevented illness caused by malnutrition. It is also known that in this era the breadbasket of the Minoan empire, the area north of the Black Sea, also suddenly lost much of its population, and thus probably some capacity to cultivate crops. Drought and famine in Anatolia may have also led to the Aegean collapse by disrupting trade networks, and therefore preventing the Aegean from accessing bronze and luxury goods. The Aegean collapse has been attributed to the exhaustion of the Cypriot forests causing the end of the bronze trade. These forests are known to have existed into later times, and experiments have shown that charcoal production on the scale necessary for the bronze production of the late Bronze Age would have exhausted them in less than fifty years. The Aegean collapse has also been attributed to the fact that as iron tools became more common, the main justification for the tin trade ended, and that trade network ceased to function as it did formerly. The colonies of the Minoan empire then suffered drought, famine, war, or some combination of those three, and had no access to the distant resources of an empire by which they could easily recover. The Thera eruption occurred 1600 BCE, north of Crete. Speculation includes that a tsunami from Thera (more commonly known today as Santorini) destroyed Cretan cities. A tsunami may have destroyed the Cretan navy in its home harbor, which then lost crucial naval battles; so that in the LMIB/LMII event ( 1450 BCE) the cities of Crete burned and the Mycenaean civilization took over Knossos. If the eruption occurred in the late 17th century BCE (as most chronologists now think) then its immediate effects belong to the Middle to Late Bronze Age transition, and not to the end of the Late Bronze Age, but it could have triggered the instability that led to the collapse first of Knossos and then of Bronze Age society overall. One such theory highlights the role of Cretan expertise in administering the empire, post—Thera. If this expertise was concentrated in Crete, then the Mycenaeans may have made political and commercial mistakes in administering the Cretan empire. Archaeological findings, including some on the island of Thera, suggest that the center of the Minoan civilization at the time of the eruption was actually on Thera rather than on Crete. According to this theory, the catastrophic loss of the political, administrative and economic center due to the eruption, as well as the damage wrought by the tsunami to the coastal towns and villages of Crete precipitated the decline of the Minoans. A weakened political entity with a reduced economic and military capability and fabled riches would have then been more vulnerable to conquest. Indeed, the Santorini eruption is usually dated to 1630 BCE, while the Mycenaean Greeks first enter the historical record a few decades later, 1600 BCE. The later Mycenaean assaults on Crete ( 1450 BCE) and Troy ( 1250 BCE) would have been a continuation of the steady encroachment of the Greeks upon the weakened Minoan world. Central Europe In Central Europe, the early Bronze Age Unetice culture (1800–1600 BCE) includes numerous smaller groups like the Straubing, Adlerberg and Hatvan cultures. Some very rich burials, such as the one located at Leubingen with grave gifts crafted from gold, point to an increase of social stratification already present in the Unetice culture. All in all, cemeteries of this period are rare and of small size. The Unetice culture is followed by the middle Bronze Age (1600–1200 BCE) Tumulus culture, which is characterised by inhumation burials in tumuli (barrows). In the eastern Hungarian Körös tributaries, the early Bronze Age first saw the introduction of the Mako culture, followed by the Otomani and Gyulavarsand cultures. The late Bronze Age Urnfield culture (1300–700 BCE) is characterized by cremation burials. It includes the Lusatian culture in eastern Germany and Poland (1300–500 BCE) that continues into the Iron Age. The Central European Bronze Age is followed by the Iron Age Hallstatt culture (700–450 BCE). Important sites include: Biskupin (Poland) Nebra (Germany) Vráble (Slovakia) Zug-Sumpf, Zug, Switzerland The Bronze Age in Central Europe has been described in the chronological schema of German prehistorian Paul Reinecke. He described Bronze A1 (Bz A1) period (2300–2000 BCE: triangular daggers, flat axes, stone wrist-guards, flint arrowheads) and Bronze A2 (Bz A2) period (1950–1700 BCE: daggers with metal hilt, flanged axes, halberds, pins with perforated spherical heads, solid bracelets) and phases Hallstatt A and B (Ha A and B). South Europe The Apennine culture (also called Italian Bronze Age) is a technology complex of central and southern Italy spanning the Chalcolithic and Bronze Age proper. The Camuni were an ancient people of uncertain origin (according to Pliny the Elder, they were Euganei; according to Strabo, they were Rhaetians) who lived in Val Camonica—in what is now northern Lombardy—during the Iron Age, although human groups of hunters, shepherds and farmers are known to have lived in the area since the Neolithic. Located in Sardinia and Corsica, the Nuragic civilization lasted from the early Bronze Age (18th century BCE) to the 2nd century CE, when the islands were already Romanized. They take their name from the characteristic Nuragic towers, which evolved from the pre-existing megalithic culture, which built dolmens and menhirs. The nuraghe towers are unanimously considered the best-preserved and largest megalithic remains in Europe. Their effective use is still debated: some scholars considered them as monumental tombs, others as Houses of the Giants, other as fortresses, ovens for metal fusion, prisons or, finally, temples for a solar cult. Around the end of the 3rd millennium BCE, Sardinia exported towards Sicily a Culture that built small dolmens, trilithic or polygonal shaped, that served as tombs as it has been ascertained in the Sicilian dolmen of “Cava dei Servi”. From this region, they reached Malta island and other countries of Mediterranean basin. The Terramare was an early Indo-European civilization in the area of what is now Pianura Padana (northern Italy) before the arrival of the Celts and in other parts of Europe. They lived in square villages of wooden stilt houses. These villages were built on land, but generally near a stream, with roads that crossed each other at right angles. The whole complex denoted the nature of a fortified settlement. Terramare was widespread in the Pianura Padana (especially along the Panaro river, between Modena and Bologna) and in the rest of Europe. The civilization developed in the Middle and Late Bronze Age, between the 17th and the 13th centuries BCE. The Castellieri culture developed in Istria during the Middle Bronze Age. It lasted for more than a millennium, from the 15th century BCE until the Roman conquest in the 3rd century BCE. It takes its name from the fortified boroughs (Castellieri, Friulian: cjastelir) that characterized the culture. The Canegrate culture developed from the mid-Bronze Age (13th century BCE) until the Iron Age in the Pianura Padana, in what are now western Lombardy, eastern Piedmont and Ticino. It takes its name from the township of Canegrate where, in the 20th century, some fifty tombs with ceramics and metal objects were found. The Canegrate culture migrated from the northwest part of the Alps and descended to Pianura Padana from the Swiss Alps passes and the Ticino. The Golasecca culture developed starting from the late Bronze Age in the Po plain. It takes its name from Golasecca, a locality next to the Ticino where, in the early 19th century, abbot Giovanni Battista Giani excavated its first findings (some fifty tombs with ceramics and metal objects). Remains of the Golasecca culture span an area of c. 20,000 square kilometers south to the Alps, between the Po, Sesia and Serio rivers, dating from the 9th to the 4th century BCE. West Europe Atlantic Bronze Age The Atlantic Bronze Age is a cultural complex of the period of approximately 1300–700 BCE that includes different cultures in Portugal, Andalusia, Galicia, and the British Isles. It is marked by economic and cultural exchange. Commercial contacts extend to Denmark and the Mediterranean. The Atlantic Bronze Age was defined by many distinct regional centers of metal production, unified by a regular maritime exchange of some of their products. Great Britain In Great Britain, the Bronze Age is considered to have been the period from around 2100 to 750 BCE. Migration brought new people to the islands from the continent. Recent tooth enamel isotope research on bodies found in early Bronze Age graves around Stonehenge indicates that at least some of the migrants came from the area of modern Switzerland. Another example site is Must Farm, near Whittlesey, which has recently been host to the most complete Bronze Age wheel ever to be found. The Beaker culture displayed different behaviors from the earlier Neolithic people, and cultural change was significant. Integration is thought to have been peaceful, as many of the early henge sites were seemingly adopted by the newcomers. The rich Wessex culture developed in southern Britain at this time. Additionally, the climate was deteriorating; where once the weather was warm and dry it became much wetter as the Bronze Age continued, forcing the population away from easily defended sites in the hills and into the fertile valleys. Large livestock farms developed in the lowlands and appear to have contributed to economic growth and inspired increasing forest clearances. The Deverel-Rimbury culture began to emerge in the second half of the Middle Bronze Age ( 1400–1100 BCE) to exploit these conditions. Devon and Cornwall were major sources of tin for much of western Europe and copper was extracted from sites such as the Great Orme mine in northern Wales. Social groups appear to have been tribal but with growing complexity and hierarchies becoming apparent. The burial of the dead (which, until this period, had usually been communal) became more individual. For example, whereas in the Neolithic a large chambered cairn or long barrow housed the dead, Early Bronze Age people buried their dead in individual barrows (also commonly known and marked on modern British Ordnance Survey maps as tumuli), or sometimes in cists covered with cairns. The greatest quantities of bronze objects in England were discovered in East Cambridgeshire, where the most important finds were recovered in Isleham (more than 6500 pieces). Alloying of copper with zinc or tin to make brass or bronze was practiced soon after the discovery of copper itself. One copper mine at Great Orme in North Wales, extended to a depth of 70 meters. At Alderley Edge in Cheshire, carbon dates have established mining at around 2280 to 1890 BCE (at 95% probability). The earliest identified metalworking site (Sigwells, Somerset) is much later, dated by Globular Urn style pottery to approximately the 12th century BCE. The identifiable sherds from over 500 mould fragments included a perfect fit of the hilt of a sword in the Wilburton style held in Somerset County Museum. Ireland The Bronze Age in Ireland commenced around 2000 BCE when copper was alloyed with tin and used to manufacture Ballybeg type flat axes and associated metalwork. The preceding period is known as the Copper Age and is characterised by the production of flat axes, daggers, halberds and awls in copper. The period is divided into three phases: Early Bronze Age (2000–1500 BCE), Middle Bronze Age (1500–1200 BCE), and Late Bronze Age (1200– 500 BCE). Ireland is also known for a relatively large number of Early Bronze Age burials. One of the characteristic types of artifact of the Early Bronze Age in Ireland is the flat axe. There are five main types of flat axes: Lough Ravel ( 2200 BCE), Ballybeg ( 2000 BCE), Killaha ( 2000 BCE), Ballyvalley ( 2000–1600 BCE), Derryniggin ( 1600 BCE), and a number of metal ingots in the shape of axes. North Europe The Bronze Age in Northern Europe spans the entire 2nd millennium BCE (Unetice culture, Urnfield culture, Tumulus culture, Terramare culture, Lusatian culture) lasting until 600 BCE. The Northern Bronze Age was both a period and a Bronze Age culture in Scandinavian pre-history, 1700–500 BCE, with sites that reached as far east as Estonia. Succeeding the Late Neolithic culture, its ethnic and linguistic affinities are unknown in the absence of written sources. It is followed by the Pre-Roman Iron Age. Even though Northern European Bronze Age cultures were relatively late, and came into existence via trade, sites present rich and well-preserved objects made of wool, wood and imported Central European bronze and gold. Many rock carvings depict ships, and the large stone burial monuments known as stone ships suggest that shipping played an important role. Thousands of rock carvings depict ships, most probably representing sewn plank built canoes for warfare, fishing, and trade. These may have a history as far back as the neolithic period and continue into the Pre-Roman Iron Age, as shown by the Hjortspring boat. There are many mounds and rock carving sites from the period. Numerous artifacts of bronze and gold are found. No written language existed in the Nordic countries during the Bronze Age. The rock carvings have been dated through comparison with depicted artifacts. Caucasus Arsenical bronze artifacts of the Maykop culture in the North Caucasus have been dated around the 4th millennium BCE. This innovation resulted in the circulation of arsenical bronze technology over southern and eastern Europe. Pontic–Caspian steppe The Yamnaya culture is a Late Copper Age/Early Bronze Age culture of the Southern Bug/Dniester/Ural region (the Pontic steppe), dating to the 36th–23rd centuries BCE. The name also appears in English as Pit-Grave Culture or Ochre-Grave Culture. The Catacomb culture, 2800–2200 BCE, comprises several related Early Bronze Age cultures occupying what is presently Russia and Ukraine. The Srubnaya culture was a Late Bronze Age (18th–12th centuries BCE) culture. It is a successor to the Yamnaya and the Poltavka culture. Africa Sub-Saharan Africa Iron and copper smelting appeared around the same time in most parts of Africa. As such, most African civilizations outside of Egypt did not experience a distinct Bronze Age. Evidence for iron smelting appears earlier or at the same time as copper smelting in Nigeria c. 900–800 BCE, Rwanda and Burundi c. 700–500 BCE and Tanzania c. 300 BCE. There is a longstanding debate about whether the development of both copper and iron metallurgy were independently developed in sub-Saharan Africa or were introduced from the outside across the Sahara Desert from North Africa or the Indian Ocean. Evidence for theories of independent development and outside introduction are scarce and subject to active scholarly debate. Scholars have suggested that both the relative dearth of archeological research in sub-Saharan Africa as well as long-standing prejudices have limited or biased our understanding of pre-historic metallurgy on the continent. One scholar characterized the state of historical knowledge as such: "To say that the history of metallurgy in sub-Saharan Africa is complicated is perhaps an understatement." West Africa Copper smelting took place in West Africa prior to the appearance of iron smelting in the region. Evidence for copper smelting furnaces was found near Agadez, Niger that has been dated as early as 2200 BCE. However, evidence for copper production in this region before 1000 BCE is debated. Evidence of copper mining and smelting has been found at Akjoujt, Mauretania that suggests small scale production 800 to 400 BCE. Americas The Moche civilization of South America independently discovered and developed bronze smelting. Bronze technology was developed further by the Incas and used widely both for utilitarian objects and sculpture. A later appearance of limited bronze smelting in West Mexico suggests either contact of that region with Andean cultures or separate discovery of the technology. The Calchaquí people of Northwest Argentina had bronze technology. Trade Trade and industry played a major role in the development of the ancient Bronze Age civilizations. With artifacts of the Indus Valley Civilization being found in ancient Mesopotamia and Egypt, it is clear that these civilizations were not only in touch with each other but also trading with each other. Early long-distance trade was limited almost exclusively to luxury goods like spices, textiles and precious metals. Not only did this make cities with ample amounts of these products extremely rich but also led to an intermingling of cultures for the first time in history. Trade routes were not only over land but also over water. The first and most extensive trade routes were over rivers such as the Nile, the Tigris and the Euphrates which led to growth of cities on the banks of these rivers. The domestication of camels at a later time also helped encourage the use of trade routes over land, linking the Indus Valley with the Mediterranean. This further led to towns sprouting up in numbers anywhere and everywhere there was a pit-stop or caravan-to-ship port.

A bidirectional text contains two text directionalities, right-to-left (RTL) and left-to-right (LTR). It generally involves text containing different types of alphabets, but may also refer to boustrophedon, which is changing text direction in each row. Many computer programs fail to display bidirectional text correctly. For example, the Hebrew name Sarah (שרה) is spelled: sin (ש) (which appears rightmost), then resh (ר), and finally heh (ה) (which should appear leftmost). Note: Some web browsers may display the Hebrew text in this article in the opposite direction. Bidirectional script support Bidirectional script support is the capability of a computer system to correctly display bidirectional text. The term is often shortened to "BiDi" or "bidi". Early computer installations were designed only to support a single writing system, typically for left-to-right scripts based on the Latin alphabet only. Adding new character sets and character encodings enabled a number of other left-to-right scripts to be supported, but did not easily support right-to-left scripts such as Arabic or Hebrew, and mixing the two was not practical. Right-to-left scripts were introduced through encodings like ISO/IEC 8859-6 and ISO/IEC 8859-8, storing the letters (usually) in writing and reading order. It is possible to simply flip the left-to-right display order to a right-to-left display order, but doing this sacrifices the ability to correctly display left-to-right scripts. With bidirectional script support, it is possible to mix characters from different scripts on the same page, regardless of writing direction. In particular, the Unicode standard provides foundations for complete BiDi support, with detailed rules as to how mixtures of left-to-right and right-to-left scripts are to be encoded and displayed. Unicode bidi support The Unicode standard calls for characters to be ordered 'logically', i.e. in the sequence they are intended to be interpreted, as opposed to 'visually', the sequence they appear. This distinction is relevant for bidi support because at any bidi transition, the visual presentation ceases to be the 'logical' one. Thus, in order to offer bidi support, Unicode prescribes an algorithm for how to convert the logical sequence of characters into the correct visual presentation. For this purpose, the Unicode encoding standard divides all its characters into one of four types: 'strong', 'weak', 'neutral', and 'explicit formatting'. Strong characters Strong characters are those with a definite direction. Examples of this type of character include most alphabetic characters, syllabic characters, Han ideographs, non-European or non-Arabic digits, and punctuation characters that are specific to only those scripts. Weak characters Weak characters are those with vague direction. Examples of this type of character include European digits, Eastern Arabic-Indic digits, arithmetic symbols, and currency symbols. Neutral characters Neutral characters have direction indeterminable without context. Examples include paragraph separators, tabs, and most other whitespace characters. Punctuation symbols that are common to many scripts, such as the colon, comma, full-stop, and the no-break-space also fall within this category. Explicit formatting Explicit formatting characters, also referred to as "directional formatting characters", are special Unicode sequences that direct the algorithm to modify its default behavior. These characters are subdivided into "marks", "embeddings", "isolates", and "overrides". Their effects continue until the occurrence of either a paragraph separator, or a "pop" character. Marks If a "weak" character is followed by another "weak" character, the algorithm will look at the first neighbouring "strong" character. Sometimes this leads to unintentional display errors. These errors are corrected or prevented with "pseudo-strong" characters. Such Unicode control characters are called marks. The mark ( or ) is to be inserted into a location to make an enclosed weak character inherit its writing direction. For example, to correctly display the for an English name brand (LTR) in an Arabic (RTL) passage, an LRM mark is inserted after the trademark symbol if the symbol is not followed by LTR text (e.g. ""). If the LRM mark is not added, the weak character ™ will be neighbored by a strong LTR character and a strong RTL character. Hence, in an RTL context, it will be considered to be RTL, and displayed in an incorrect order (e.g. ""). Embeddings The "embedding" directional formatting characters are the classical Unicode method of explicit formatting, and as of Unicode 6.3, are being discouraged in favor of "isolates". An "embedding" signals that a piece of text is to be treated as directionally distinct. The text within the scope of the embedding formatting characters is not independent of the surrounding text. Also, characters within an embedding can affect the ordering of characters outside. Unicode 6.3 recognized that directional embeddings usually have too strong an effect on their surroundings and are thus unnecessarily difficult to use. Isolates The "isolate" directional formatting characters signal that a piece of text is to be treated as directionally isolated from its surroundings. As of Unicode 6.3, these are the formatting characters that are being encouraged in new documents – once target platforms are known to support them. These formatting characters were introduced after it became apparent that directional embeddings usually have too strong an effect on their surroundings and are thus unnecessarily difficult to use. Unlike the legacy 'embedding' directional formatting characters, 'isolate' characters have no effect on the ordering of the text outside their scope. Isolates can be nested, and may be placed within embeddings and overrides. Overrides The "override" directional formatting characters allow for special cases, such as for part numbers (e.g. to force a part number made of mixed English, digits and Hebrew letters to be written from right to left), and are recommended to be avoided wherever possible. As is true of the other directional formatting characters, "overrides" can be nested one inside another, and in embeddings and isolates. Pops The "pop" directional formatting characters terminate the scope of the most recent "embedding", "override", or "isolate". Runs In the algorithm, each sequence of concatenated strong characters is called a "run". A "weak" character that is located between two "strong" characters with the same orientation will inherit their orientation. A "weak" character that is located between two "strong" characters with a different writing direction, will inherit the main context's writing direction (in an LTR document the character will become LTR, in an RTL document, it will become RTL). Table of possible BiDi character types Security Unicode bidirectional characters are used in the Trojan Source vulnerability. Visual Studio Code highlights BiDi control characters since version 1.62 released on October 2021. Visual Studio highlights BiDi control characters since version 17.0.3 released on December 14, 2021. Scripts using bidirectional text Egyptian hieroglyphs Egyptian hieroglyphs can be written bidirectionally, where the signs had a distinct "head" that faced the beginning of a line and "tail" that faced the end. Chinese characters and other CJK scripts Chinese characters can be written in either direction as well as vertically (top to bottom then right to left), especially in signs (such as plaques), but the orientation of the individual characters is never changed. This can often be seen on tour buses in China, where the company name customarily runs from the front of the vehicle to its rear — that is, from right to left on the right side of the bus, and from left to right on the left side of the bus. English texts on the right side of the vehicle are also quite commonly written in reverse order. (See pictures of tour bus and post vehicle below.) Likewise, other CJK scripts made up of the same square characters, such as the Japanese writing system and Korean writing system, can also be written in any direction, although left-to-right, top-to-bottom and, right-to-left are most common. Boustrophedon Boustrophedon is a writing style found in ancient Greek inscriptions and in Hungarian runes. This method of writing alternates direction, and usually reverses the individual characters, on each successive line. Moon type Moon type is an embossed adaptation of the Latin alphabet invented as a tactile alphabet for the blind. Initially the text changed direction (but not character orientation) at the end of the lines. Special embossed lines connected the end of a line and the beginning of the next. Around 1990, it changed to a left-to-right orientation.

Blitz BASIC is the programming language dialect of the first Blitz compilers, devised by New Zealand-based developer Mark Sibly. Being derived from BASIC, Blitz syntax was designed to be easy to pick up for beginners first learning to program. The languages are game-programming oriented but are often found general-purpose enough to be used for most types of application. The Blitz language evolved as new products were released, with recent incarnations offering support for more advanced programming techniques such as object-orientation and multithreading. This led to the languages losing their BASIC moniker in later years. History The first iteration of the Blitz language was created for the Amiga platform and published by the Australian firm Memory and Storage Technology. Returning to New Zealand, Blitz BASIC 2 was published several years later (around 1993 according this press release ) by Acid Software (a local Amiga game publisher). Since then, Blitz compilers have been released on several platforms. Following the demise of the Amiga as a commercially viable platform, the Blitz BASIC 2 source code was released to the Amiga community. Development continues to this day under the name AmiBlitz. BlitzBasic Idigicon published BlitzBasic for Microsoft Windows in October 2000. The language included a built-in API for performing basic 2D graphics and audio operations. Following the release of Blitz3D, BlitzBasic is often synonymously referred to as Blitz2D. Recognition of BlitzBasic increased when a limited range of "free" versions were distributed in popular UK computer magazines such as PC Format. This resulted in a legal dispute between the developer and publisher which was eventually resolved amicably. BlitzPlus In February 2003, Blitz Research Ltd. released BlitzPlus also for Microsoft Windows. It lacked the 3D engine of Blitz3D, but did bring new features to the 2D side of the language by implementing limited Microsoft Windows control support for creating native GUIs. Backwards compatibility of the 2D engine was also extended, allowing compiled BlitzPlus games and applications to run on systems that might only have DirectX 1. BlitzMax The first BlitzMax compiler was released in December 2004 for Mac OS X. This made it the first Blitz dialect that could be compiled on *nix platforms. Compilers for Microsoft Windows and Linux were subsequently released in May 2005. BlitzMax brought the largest change of language structure to the modern range of Blitz products by extending the type system to include object-oriented concepts and modifying the graphics API to better suit OpenGL. BlitzMax was also the first of the Blitz languages to represent strings internally using UCS-2, allowing native-support for string literals composed of non-ASCII characters. BlitzMax's platform-agnostic command-set allows developers to compile and run source code on multiple platforms. However the official compiler and build chain will only generate binaries for the platform that it is executing on. Unofficially, users have been able to get Linux and Mac OS X to cross-compile to the Windows platform. BlitzMax is also the first modular version of the Blitz languages, improving the extensibility of the command-set. In addition, all of the standard modules shipped with the compiler are open-source and so can be tweaked and recompiled by the programmer if necessary. The official BlitzMax cross-platform GUI module (known as MaxGUI) allows developers to write GUI interfaces for their applications on Linux (FLTK), Mac (Cocoa) and Windows. Various user-contributed modules extend the use of the language by wrapping such libraries as wxWidgets, Cairo, and Fontconfig as well as a selection of database modules. There are also a selection of third-party 3D modules available namely MiniB3D - an open-source OpenGL engine which can be compiled and used on all three of BlitzMax's supported platforms. In October 2007, BlitzMax 1.26 was released which included the addition of a reflection module. BlitzMax 1.32 shipped new threading and Lua scripting modules and most of the standard library functions have been updated so that they are unicode friendly. Blitz3D SDK Blitz3D SDK is a 3D graphics engine based on the engine in Blitz3D. It was marketed for use with C++, C#, BlitzMax, and PureBasic, however it could also be used with other languages that follow compatible calling conventions. Max3D module In 2008, the source code to Max3D - a C++-based cross-platform 3D engine - was released under a BSD license. This engine focused on OpenGL but had an abstract backend for other graphics drivers (such as DirectX) and made use of several open-source libraries, namely Assimp, Boost, and ODE. Despite the excitement in the Blitz community of Max3D being the eagerly awaited successor to Blitz3D, interest and support died off soon after the source code was released and eventually development came to a halt. There is no indication that Blitz Research will pick up the project again. Open-source release BlitzPlus was released as open-source on 28 April 2014 under the zlib license on GitHub. Blitz3D followed soon after and was released as Open Source on 3 August 2014. BlitzMax was later released as Open Source on 21 September 2015.

The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 82,040 regular full-time personnel, 3,960 Gurkhas, and 29,740 reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term British Army was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The British Army, composed primarily of cavalry and infantry, was originally one of two Regular Forces within the British military (those parts of the British Armed Forces tasked with land warfare, as opposed to the naval forces), with the other having been the Ordnance Military Corps (made up of the Royal Artillery, Royal Engineers, and the Royal Sappers and Miners) of the Board of Ordnance, which along with the originally civilian Commissariat Department, stores and supply departments, as well as barracks and other departments were absorbed into the British Army when the Board of Ordnance was abolished in 1855 (various other civilian departments of the board were absorbed into the War Office). The British Army has seen action in major wars between the world's great powers, including the Seven Years' War, the American Revolutionary War, the Napoleonic Wars, the Crimean War and the First and Second World Wars. Britain's victories in most of these decisive wars allowed it to influence world events and establish itself as one of the world's leading military and economic powers. Since the end of the Cold War, the British Army has been deployed to a number of conflict zones, often as part of an expeditionary force, a coalition force or part of a United Nations peacekeeping operation. History Formation Until the English Civil War, England never had a standing army with professional officers and careerist corporals and sergeants. It relied on militia organised by local officials or private forces mobilised by the nobility, or on hired mercenaries from Europe. From the later Middle Ages until the English Civil War, when a foreign expeditionary force was needed, such as the one that Henry V of England took to France and that fought at the Battle of Agincourt (1415), the army, a professional one, was raised for the duration of the expedition. During the English Civil War, the members of the Long Parliament realised that the use of county militia organised into regional associations (such as the Eastern Association), often commanded by local members of parliament (both from the House of Commons and the House of Lords), while more than able to hold their own in the regions which Parliamentarians controlled, were unlikely to win the war. So Parliament initiated two actions. The Self-denying Ordinance forbade members of parliament (with the notable exception of Oliver Cromwell) from serving as officers in the Parliamentary armies. This created a distinction between the civilians in Parliament, who tended to be Presbyterian and conciliatory to the Royalists in nature, and a corps of professional officers, who tended to be Independent (Congregational) in theology, to whom they reported. The second action was legislation for the creation of a Parliamentary-funded army, commanded by Lord General Thomas Fairfax, which became known as the New Model Army (originally new-modelled Army). While this proved to be a war-winning formula, the New Model Army, being organised and politically active, went on to dominate the politics of the Interregnum and by 1660 was widely disliked. The New Model Army was paid off and disbanded at the Restoration of the monarchy in 1660. For many decades the alleged excesses of the New Model Army under the Protectorate of Oliver Cromwell were used as propaganda (and still feature in Irish folklore) and the Whig element recoiled from allowing a standing army. The militia acts of 1661 and 1662 prevented local authorities from calling up militia and oppressing their own local opponents. Calling up the militia was possible only if the king and local elites agreed to do so. Charles II and his Cavalier supporters favoured a new army under royal control, and immediately after the Restoration began working on its establishment. The first English Army regiments, including elements of the disbanded New Model Army, were formed between November 1660 and January 1661 and became a standing military force for England (financed by Parliament). The Royal Scots and Irish Armies were financed by the parliaments of Scotland and Ireland. Parliamentary control was established by the Bill of Rights 1689 and Claim of Right Act 1689, although the monarch continued to influence aspects of army administration until at least the end of the nineteenth century. After the Restoration Charles II pulled together four regiments of infantry and cavalry, calling them his guards, at a cost of £122,000 from his general budget. This became the foundation of the permanent English Army. By 1685 it had grown to 7,500 soldiers in marching regiments, and 1,400 men permanently stationed in garrisons. A rebellion in 1685 allowed James II to raise the forces to 20,000 men. There were 37,000 in 1678 when England played a role in the closing stage of the Franco-Dutch War. After William and Mary's accession to the throne, England involved itself in the War of the Grand Alliance, primarily to prevent a French invasion restoring James II (Mary's father). In 1689, William III expanded the army to 74,000, and then to 94,000 in 1694. Parliament was very nervous and reduced the cadre to 7000 in 1697. Scotland and Ireland had theoretically separate military establishments, but they were unofficially merged with the English force. By the time of the 1707 Acts of Union, many regiments of the English and Scottish armies were combined under one operational command and stationed in the Netherlands for the War of the Spanish Succession. Although all the regiments were now part of the new British military establishment, they remained under the old operational-command structure and retained much of the institutional ethos, customs and traditions of the standing armies created shortly after the restoration of the monarchy 47 years earlier. The order of seniority of the most-senior British Army line regiments is based on that of the English army. Although technically the Scots Royal Regiment of Foot was raised in 1633 and is the oldest Regiment of the Line, Scottish and Irish regiments were only allowed to take a rank in the English army on the date of their arrival in England (or the date when they were first placed on the English establishment). In 1694, a board of general officers was convened to decide the rank of English, Irish and Scots regiments serving in the Netherlands; the regiment which became known as the Scots Greys were designated the 4th Dragoons because there were three English regiments raised prior to 1688 when the Scots Greys were first placed in the English establishment. In 1713, when a new board of general officers was convened to decide the rank of several regiments, the seniority of the Scots Greys was reassessed and based on their June 1685 entry into England. At that time there was only one English regiment of dragoons, and the Scots Greys eventually received the British Army rank of 2nd Dragoons. British Empire (1700–1914) After 1700 British continental policy was to contain expansion by competing powers such as France and Spain. Although Spain was the dominant global power during the previous two centuries and the chief threat to England's early transatlantic ambitions, its influence was now waning. The territorial ambitions of the French, however, led to the War of the Spanish Succession and the Napoleonic Wars. Although the Royal Navy is widely regarded as vital to the rise of the British Empire, the British Army played an important role in the formation of colonies, protectorates and dominions in the Americas, Africa, Asia, India and Australasia. British soldiers captured strategically important territories, and the army was involved in wars to secure the empire's borders and support friendly governments. Among these actions were the Seven Years' War, the American Revolutionary War, the Napoleonic Wars, the First and Second Opium Wars, the Boxer Rebellion, the New Zealand Wars, the Australian frontier wars, the Sepoy Rebellion of 1857, the first and second Boer Wars, the Fenian raids, the Irish War of Independence, interventions in Afghanistan (intended to maintain a buffer state between British India and the Russian Empire) and the Crimean War (to keep the Russian Empire at a safe distance by aiding Turkey). Like the English Army, the British Army fought the kingdoms of Spain, France (including the Empire of France) and the Netherlands for supremacy in North America and the West Indies. With native and provincial assistance, the army conquered New France in the North American theatre of the Seven Years' War and suppressed a Native American uprising in Pontiac's War. The British Army was defeated in the American Revolutionary War, losing the Thirteen Colonies but retaining The Canadas and The Maritimes as British North America, including Bermuda (originally part of Virginia, and which had been strongly sympathetic to the rebels early in the war). Halifax, Nova Scotia and Bermuda were to become Imperial fortresses (although Bermuda, being safer from attack over water and impervious to attack overland, quickly became the most important in British North America), along with Malta and Gibraltar, providing bases for Royal Navy squadrons to control the oceans, and heavily garrisoned by the British Army both for defence of the bases and to provide military forces to work with the navy in amphibious operations throughout their regions. The British Army was heavily involved in the Napoleonic Wars, participating in a number of campaigns in Europe (including continuous deployment in the Peninsular War), the Caribbean, North Africa and North America. The war between the British and the First French Empire of Napoleon Bonaparte stretched around the world; at its peak in 1813, the regular army contained over 250,000 men. A coalition of Anglo-Dutch and Prussian armies under the Duke of Wellington and Field Marshal von Blücher finally defeated Napoleon at Waterloo in 1815. The English were involved politically and militarily in Ireland since receiving the Lordship of Ireland from the pope in 1171. The campaign of English republican Protector Oliver Cromwell involved uncompromising treatment of the Irish towns (most notably Drogheda and Wexford) which supported the Royalists during the English Civil War. The English Army (and the subsequent British Army) remained in Ireland primarily to suppress Irish revolts or disorder. In addition to its conflict with Irish nationalists, it was faced with the prospect of battling Anglo-Irish and Ulster Scots in Ireland who were angered by unfavourable taxation of Irish produce imported into Britain. With other Irish groups, they raised a volunteer army and threatened to emulate the American colonists if their conditions were not met. Learning from their experience in America, the British government sought a political solution. The British Army fought Irish rebels—Protestant and Catholic—primarily in Ulster and Leinster (Wolfe Tone's United Irishmen) in the 1798 rebellion. In addition to battling the armies of other European empires (and its former colonies, the United States, in the American War of 1812), the British Army fought the Chinese in the First and Second Opium Wars and the Boxer Rebellion, Māori tribes in the first of the New Zealand Wars, Nawab Shiraj-ud-Daula's forces and British East India Company mutineers in the Sepoy Rebellion of 1857, the Boers in the first and second Boer Wars, Irish Fenians in Canada during the Fenian raids and Irish separatists in the Anglo-Irish War. The increasing demands of imperial expansion and the inadequacy and inefficiency of the underfunded British Army, Militia, Yeomanry and Volunteer Force after the Napoleonic Wars led to series of reforms following the failures of the Crimean War. Inspired by the successes of the Prussian Army (which relied on short-term conscription of all eligible young men to maintain a large reserve of recently discharged soldiers, ready to be recalled on the outbreak of war to immediately bring the small peacetime regular army up to strength), the Regular Reserve of the British Army was originally created in 1859 by Secretary of State for War Sidney Herbert, and re-organised under the Reserve Force Act, 1867. Prior to this, a soldier was generally enlisted into the British Army for a 21-year engagement, following which (should he survive so long) he was discharged as a Pensioner. Pensioners were sometimes still employed on garrison duties, as were younger soldiers no longer deemed fit for expeditionary service who were generally organised in invalid units or returned to the regimental depot for home service. The cost of paying pensioners, and the obligation the government was under to continue to employ invalids as well as soldiers deemed by their commanding officers as detriments to their units were motivations to change this system. The long period of engagement also discouraged many potential recruits. The long service enlistments were consequently replaced with short service enlistments, with undesirable soldiers not permitted to re-engage on the completion of their first engagement. The size of the army also fluctuated greatly, increasing in war time, and drastically shrinking with peace. Battalions posted on garrison duty overseas were allowed an increase on their normal peacetime establishment, which resulted in their having surplus men on their return to a Home station. Consequently, soldiers engaging on short term enlistments were enabled to serve several years with the colours and the remainder in the Regular Reserve, remaining liable for recall to the colours if required. Among the other benefits, this thereby enabled the British Army to have a ready pool of recently trained men to draw upon in an emergency. The name of the Regular Reserve (which for a time was divided into a First Class and a Second Class) has resulted in confusion with the Reserve Forces, which were the pre-existing part-time, local-service home-defence forces that were auxiliary to the British Army (or Regular Force), but not originally part of it: the Yeomanry, Militia (or Constitutional Force) and Volunteer Force. These were consequently also referred to as Auxiliary Forces or Local Forces. The late-19th-century Cardwell and Childers Reforms gave the army its modern shape and redefined its regimental system. The 1907 Haldane Reforms created the Territorial Force as the army's volunteer reserve component, merging and reorganising the Volunteer Force, Militia and Yeomanry. World Wars (1914–1945) Great Britain was challenged by other powers, primarily the German Empire and Nazi Germany, during the 20th century. A century earlier it vied with Napoleonic France for global pre-eminence, and Hanoverian Britain's natural allies were the kingdoms and principalities of northern Germany. By the middle of the 19th century, Britain and France were allies in preventing Russia's appropriation of the Ottoman Empire, although the fear of French invasion led shortly afterwards to the creation of the Volunteer Force. By the first decade of the 20th century, the United Kingdom was allied with France (by the Entente Cordiale) and Russia (which had a secret agreement with France for mutual support in a war against the Prussian-led German Empire and the Austro-Hungarian Empire). When the First World War broke out in August 1914 the British Army sent the British Expeditionary Force (BEF), consisting mainly of regular army troops, to France and Belgium. The fighting bogged down into static trench warfare for the remainder of the war. In 1915 the army created the Mediterranean Expeditionary Force to invade the Ottoman Empire via Gallipoli, an unsuccessful attempt to capture Constantinople and secure a sea route to Russia. The First World War was the most devastating in British military history, with nearly 800,000 men killed and over two million wounded. Early in the war, the BEF was virtually destroyed and was replaced first by volunteers and then by a conscript force. Major battles included those at the Somme and Passchendaele. Advances in technology saw the advent of the tank (and the creation of the Royal Tank Regiment) and advances in aircraft design (and the creation of the Royal Flying Corps) which would be decisive in future battles. Trench warfare dominated Western Front strategy for most of the war, and the use of chemical weapons (disabling and poison gases) added to the devastation. The Second World War broke out in September 1939 with the Russian and German Army's invasion of Poland. British assurances to the Poles led the British Empire to declare war on Germany. As in the First World War, a relatively small BEF was sent to France but then hastily evacuated from Dunkirk as the German forces swept through the Low Countries and across France in May 1940. After the British Army recovered from its earlier defeats, it defeated the Germans and Italians at the Second Battle of El Alamein in North Africa in 1942–1943 and helped drive them from Africa. It then fought through Italy and, with the help of American, Canadian, Australian, New Zealand, Indian and Free French forces, and took part in the D-Day invasion of Normandy on 6 June 1944; nearly half the Allied soldiers were British. In the Far East, the British Army rallied against the Japanese in the Burma Campaign and regained the British Far Eastern colonial possessions. Postcolonial era (1945–2000) After the Second World War the British Army was significantly reduced in size, although National Service continued until 1960. This period saw decolonisation begin with the partition and independence of India and Pakistan, followed by the independence of British colonies in Africa and Asia. The Corps Warrant, which is the official list of which bodies of the British Military (not to be confused with naval) Forces were to be considered Corps of the British Army for the purposes of the Army Act, the Reserve Forces Act, 1882, and the Territorial and Reserve Forces Act, 1907, had not been updated since 1926 (Army Order 49 of 1926), although amendments had been made up to and including Army Order 67 of 1950. A new Corps Warrant was declared in 1951. Although the British Army was a major participant in Korea in the early 1950s and Suez in 1956, during this period Britain's role in world events was reduced and the army was downsized. The British Army of the Rhine, consisting of I (BR) Corps, remained in Germany as a bulwark against Soviet invasion. The Cold War continued, with significant technological advances in warfare, and the army saw the introduction of new weapons systems. Despite the decline of the British Empire, the army was engaged in Aden, Indonesia, Cyprus, Kenya and Malaya. In 1982, the British Army and the Royal Marines helped liberate the Falkland Islands during the conflict with Argentina after that country's invasion of the British territory. In the three decades following 1969, the army was heavily deployed in Northern Ireland's Operation Banner to support the Royal Ulster Constabulary (later the Police Service of Northern Ireland) in their conflict with republican paramilitary groups. The locally recruited Ulster Defence Regiment was formed, becoming home-service battalions of the Royal Irish Regiment in 1992 before it was disbanded in 2006. Over 700 soldiers were killed during the Troubles. Following the 1994–1996 IRA ceasefires and since 1997, demilitarisation has been part of the peace process and the military presence has been reduced. On 25 June 2007 the 2nd Battalion of the Princess of Wales's Royal Regiment left the army complex in Bessbrook, County Armagh, ending the longest operation in British Army history. Persian Gulf War The British Army contributed 50,000 troops to the coalition which fought Iraq in the Persian Gulf War, and British forces controlled Kuwait after its liberation. Forty-seven British military personnel died during the war. Balkan conflicts The army was deployed to former Yugoslavia in 1992. Initially part of the United Nations Protection Force, in 1995 its command was transferred to the Implementation Force (IFOR) and then to the Stabilisation Force in Bosnia and Herzegovina (SFOR); the commitment rose to over 10,000 troops. In 1999, British forces under SFOR command were sent to Kosovo and the contingent increased to 19,000 troops. Between early 1993 and June 2010, 72 British military personnel died during operations in the former Yugoslavian countries of Bosnia, Kosovo and Macedonia. The Troubles Although there have been permanent garrisons in Northern Ireland throughout its history, the British Army was deployed as a peacekeeping force from 1969 to 2007 in Operation Banner. Initially, this was (in the wake of unionist attacks on nationalist communities in Derry and Belfast) to prevent further loyalist attacks on Catholic communities; it developed into support of the Royal Ulster Constabulary (RUC) and its successor, the Police Service of Northern Ireland (PSNI) against the Provisional Irish Republican Army (PIRA). Under the 1998 Good Friday Agreement, there was a gradual reduction in the number of soldiers deployed. In 2005, after the PIRA declared a ceasefire, the British Army dismantled posts, withdrew many troops and restored troop levels to those of a peacetime garrison. Operation Banner ended at midnight on 31 July 2007 after about 38 years of continuous deployment, the longest in British Army history. According to an internal document released in 2007, the British Army had failed to defeat the IRA but made it impossible for them to win by violence. Operation Helvetic replaced Operation Banner in 2007, maintaining fewer service personnel in a more-benign environment. Of the 300,000 troops who served in Northern Ireland since 1969, there were 763 British military personnel killed and 306 killed by the British military, mostly civilians. An estimated 100 soldiers committed suicide during Operation Banner or soon afterwards and a similar number died in accidents. A total of 6,116 were wounded. Sierra Leone The British Army deployed to Sierra Leone for Operation Palliser in 1999, under United Nations resolutions, to aid the government in quelling violent uprisings by militiamen. British troops also provided support during the 2014 West African Ebola virus epidemic. Recent history (2000–present) War in Afghanistan In November 2001, as part of Operation Enduring Freedom with the United States, the United Kingdom deployed forces in Afghanistan to topple the Taliban in Operation Herrick. The 3rd Division were sent to Kabul to assist in the liberation of the capital and defeat Taliban forces in the mountains. In 2006 the British Army began concentrating on fighting Taliban forces and bringing security to Helmand Province, with about 9,500 British troops (including marines, airmen and sailors) deployed at its peak—the second-largest force after that of the US. In December 2012 Prime Minister David Cameron announced that the combat mission would end in 2014, and troop numbers gradually fell as the Afghan National Army took over the brunt of the fighting. Between 2001 and 26 April 2014 a total of 453 British military personnel died in Afghan operations. Operation Herrick ended with the handover of Camp Bastion on 26 October 2014, but the British Army maintains a deployment in Afghanistan as part of Operation Toral. Following an announcement by the US Government of the end of their operations in the Afghanistan, the Ministry of Defence announced in April 2021 that British forces would withdraw from the country by 11 September 2021. It was later reported that all UK troops would be out by early July. Following the collapse of the Afghan Army, and the completion of the withdrawal of civilians, all British troops had left by the end of August 2021. Iraq War In 2003 the United Kingdom was a major contributor to the invasion of Iraq, sending a force of over 46,000 military personnel. The British Army controlled southern Iraq, and maintained a peace-keeping presence in Basra. All British troops were withdrawn from Iraq by 30 April 2009, after the Iraqi government refused to extend their mandate. One hundred and seventy-nine British military personnel died in Iraqi operations. The British Armed Forces returned to Iraq in 2014 as part of Operation Shader to counter the Islamic State (ISIL). Recent military aid The British Army maintains a standing liability to support the civil authorities in certain circumstances, usually in either niche capabilities (e.g. explosive ordnance removal) or in general support of the civil authorities when their capacity is exceeded. In recent years this has been seen as army personnel supporting the civil authorities in the face of the 2001 United Kingdom foot-and-mouth outbreak, the 2002 firefighters strike, widespread flooding in 2005, 2007, 2009, 2013 and 2014, Operation Temperer following the Manchester Arena bombing in 2017 and, most recently, Operation Rescript during the COVID-19 pandemic. Modern army Personnel The British Army has been a volunteer force since national service ended during the 1960s. Since the creation of the part-time, reserve Territorial Force in 1908 (renamed the Army Reserve in 2014), the full-time British Army has been known as the Regular Army. In July 2020 there were just over 78,800 Regulars, with a target strength of 82,000, and just over 30,000 Army Reservists, with a target strength of 30,000. All former Regular Army personnel may also be recalled to duty in exceptional circumstances during the 6-year period following completion of their Regular service, which creates an additional force known as the Regular Reserve. The table below illustrates British Army personnel figures from 1710 to 2020. Equipment Infantry The British Army's basic weapon is the 5.56 mm L85A2 or L85A3 assault rifle, with some specialist personnel using the L22A2 carbine variant (pilots and some tank crew). The weapon was traditionally equipped with either iron sights or an optical SUSAT, although other optical sights have been subsequently purchased to supplement these. The weapon can be enhanced further utilising the Picatinny rail with attachments such as the L17A2 under-barrel grenade launcher. Some soldiers are equipped with the 7.62mm L129A1 sharpshooter rifle, which in 2018 formally replaced the L86A2 Light Support Weapon. Support fire is provided by the L7 general-purpose machine gun (GPMG), and indirect fire is provided by L16 81mm mortars. Sniper rifles include the L118A1 7.62 mm, L115A3 and the AW50F, all manufactured by Accuracy International. The British Army utilises the Glock 17 as its side arm. Armour The army's main battle tank is the Challenger 2. It is supported by the Warrior Infantry Fighting Vehicle as the primary armoured personnel carrier and the many variants of the Combat Vehicle Reconnaissance (Tracked) and Bulldog. Light armoured units often utilise the Supacat "Jackal" MWMIK and Coyote for reconnaissance and fire support. Artillery The army has three main artillery systems: the Multi Launch Rocket System (MLRS), the AS-90 and the L118 light gun. The MLRS, first used in Operation Granby, has an range. The AS-90 is a 155 mm self-propelled armoured gun with a range. The L118 light gun is a 105 mm towed gun. To identify artillery targets, the army operates weapon locators such as the MAMBA Radar and utilises artillery sound ranging. For air defence it uses the Short-Range Air Defence (SHORAD) Rapier FSC missile system, widely deployed since the Falklands War, and the Very Short-Range Air Defence (VSHORAD) Starstreak HVM (high-velocity missile) launched by a single soldier or from a vehicle-mounted launcher. Protected mobility Where armour is not required or mobility and speed are favoured the British Army utilises protected patrol vehicles, such as the Panther variant of the Iveco LMV, the Foxhound, and variants of the Cougar family (such as the Ridgeback, Husky and Mastiff). For day-to-day utility work the army commonly uses the Land Rover Wolf, which is based on the Land Rover Defender. Engineers, utility and signals Specialist engineering vehicles include bomb-disposal robots and the modern variants of the Armoured Vehicle Royal Engineers, including the Titan bridge-layer, Trojan combat-engineer vehicle, Terrier Armoured Digger and Python Minefield Breaching System. Day-to-day utility work uses a series of support vehicles, including six-, nine- and fifteen-tonne trucks (often called "Bedfords", after a historic utility vehicle), heavy-equipment transporters (HET), close-support tankers, quad bikes and ambulances. Tactical communication uses the Bowman radio system, and operational or strategic communication is controlled by the Royal Corps of Signals. Aviation The Army Air Corps (AAC) provides direct aviation support, with the Royal Air Force providing support helicopters. The primary attack helicopter is the Westland WAH-64 Apache, a licence-built, modified version of the US AH-64 Apache which replaced the Westland Lynx AH7 in the anti-tank role. Other helicopters include the Westland Gazelle (a light surveillance aircraft), the Bell 212 (in jungle "hot and high" environments) and the AgustaWestland AW159 Wildcat, a dedicated intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) helicopter. The Eurocopter AS 365N Dauphin is used for special operations aviation, and the Britten-Norman Islander is a light, fixed-wing aircraft used for airborne reconnaissance and command and control. The army operates two unmanned aerial vehicles ('UAV's) in a surveillance role: the small Lockheed Martin Desert Hawk III and the larger Thales Watchkeeper WK450. Current deployments Low-intensity operations Permanent overseas postings Structure Army Headquarters is located in Andover, Hampshire, and is responsible for providing forces at operational readiness for employment by the Permanent Joint Headquarters. The command structure is hierarchical, with overall command residing with the Chief of the General Staff (CGS), who is immediately subordinate to The Chief of Defence Staff, the head of the British Armed Services. The CGS is supported by the Deputy Chief of the General Staff. Army Headquarters is further organised into two subordinate commands, Field Army and Home Command, each commanded by a lieutenant general. These two Commands serve distinct purposes and are divided into a structure of divisions and brigades, which themselves consist of a complex mix of smaller units such as Battalions. British Army units are either full-time 'Regular' units, or part-time Army Reserve units. Field Army Led by Commander Field Army, the Field Army is responsible for generating and preparing forces for current and contingency operations. The Field Army comprises 1st (United Kingdom) Division 3rd (United Kingdom) Division which is the United Kingdom's strategic land warfare asset 6th (United Kingdom) Division 16 Air Assault Brigade is the British Army's Air Assault formation Land Warfare Centre (United Kingdom) which is responsible for driving adaptation in order to deliver success on operations. Home Command Home Command is the British Army's supporting command; a generating, recruiting and training force that supports the Field Army and delivers UK resilience. It comprises Army Personnel Centre, which deals with personnel issues and liaises with outside agencies. Army Personnel Services Group, which supports personnel administration HQ Army Recruiting and Initial Training Command, which is responsible for all recruiting and training of Officers and Soldiers. London District Command, which is the main headquarters for all British Army units within the M25 corridor of London. It also provides for London's ceremonial events as well as supporting operational deployments overseas. Regional Command, which enables the delivery of a secure home front that sustains the Army, notably helping to coordinate the British Army's support to the civil authorities, overseeing the British Army's Welfare Service, and delivering the British Army's civil engagement mission. Standing Joint Command, which coordinates defence's contribution to UK resilience operations in support of other government departments. Special Forces The British Army contributes two of the three special forces formations to the United Kingdom Special Forces directorate: the Special Air Service (SAS) and Special Reconnaissance Regiment (SRR). The SAS consists of one regular and two reserve regiments. The regular regiment, 22 SAS, has its headquarters at Stirling Lines, Credenhill, Herefordshire. It consists of 5 squadrons (A, B, D, G and Reserve) and a training wing. 22 SAS is supported by 2 reserve regiments, 21 SAS and 23 SAS, which collectively form the Special Air Service (Reserve) (SAS [R]), who in 2020 were transferred back under the command of Director of Special Forces after previously being under the command of the 1st Intelligence, Surveillance and Reconnaissance Brigade. The SRR, formed in 2005, performs close reconnaissance and special surveillance tasks. The Special Forces Support Group, under the operational control of the Director of Special Forces, provides operational manoeuvring support to the United Kingdom Special Forces. Colonial units The British Army historically included many units from what are now separate Commonwealth realms. When the English Empire was established in North America, Bermuda, and the West Indies in the early 17th century there was no standing English Army, only the Militia, Yeomanry, and Royal bodyguards, of which the Militia, as the primary home-defence force, was immediately extended to the colonies. Colonial militias defended colonies single-handedly at first against indigenous peoples and European competitors. Once the standing English Army, later the British Army, came into existence and began to garrison the colonies, the colonial militias fought side by side with it in a number of wars, including the Seven Years' War. Some of the colonial militias rebelled during the American War of Independence. The militia fought alongside the regular British Army (and native allies) in defending British North America from their former countrymen during the War of 1812. Locally raised units in strategically located Imperial fortress colonies (including: Nova Scotia before the Canadian Confederation; Bermuda - which was treated as part of The Maritimes under the Commander-in-Chief at Nova Scotia until Canadian Confederation; Gibraltar; and Malta) and the Channel Islands were generally maintained from army funds and more fully integrated into the British Army as evident from their appearances in British Army lists, unlike units such as the King's African Rifles. The larger colonies (Australia, New Zealand, Canada, South Africa, etc.) mostly achieved Commonwealth Dominion status before or after the First World War and were granted full legislative independence in 1931. While remaining within the British Empire, this placed their governments on a par with the British government, and hence their military units comprised separate armies (e.g. the Australian Army), although Canada retained the term "militia" for its military forces until the Second World War. From the 1940s, these dominions and many colonies chose full independence, usually becoming Commonwealth realms (as member states of the Commonwealth are known today). Units raised in self-governing and Crown colonies (those without local elected Legislatures, as was the case with British Hong Kong) that are part of the British realm remain under British Government control. As the territorial governments are delegated responsibility only for internal government, the UK Government, as the government of the Sovereign state, retains responsibility for national security and the defence of the fourteen remaining British Overseas Territories, of which six have locally raised regiments: Royal Bermuda Regiment Royal Gibraltar Regiment Falkland Islands Defence Force Royal Montserrat Defence Force Cayman Islands Regiment Turks and Caicos Regiment Levels of Command The structure of the British Army beneath the level of Divisions and Brigades is also hierarchical and command is based on rank. The table below details how many units within the British Army are structured, although there can be considerable variation between individual units: Whilst many units are organised as Battalions or Regiments administratively, the most common fighting unit is the combined arms unit known as a Battlegroup. This is formed around a combat unit and supported by units (or sub-units) from other capabilities. An example of a battlegroup would be two companies of armoured infantry (e.g. from the 1st Battalion of the Mercian Regiment), one squadron of heavy armour (e.g. A Squadron of the Royal Tank Regiment), a company of engineers (e.g. B Company of the 22nd Engineer Regiment), a Battery of artillery (e.g. D Battery of the 1st Regiment of the Royal Horse Artillery) and smaller attachments from medical, logistic and intelligence units. Typically organised and commanded by a battlegroup headquarters and named after the unit which provided the most combat units, in this example, it would be the 1 Mercian Battlegroup. This creates a self-sustaining mixed formation of armour, infantry, artillery, engineers and support units, commanded by a lieutenant colonel. Recruitment The British Army primarily recruits from within the United Kingdom, but accept applications from all British citizens. It also accepts applications from Irish citizens and Commonwealth citizens, with certain restrictions. Since 2018 the British Army has been an equal-opportunity employer (with some legal exceptions due to medical standards), and does not discriminate based on race, religion or sexual orientation. Applicants for the Regular Army must be a minimum age of 16, although soldiers under 18 may not serve in operations, and the maximum age is 36. Applicants for the Army Reserve must be a minimum of 17 years and 9 months, and a maximum age of 43. Different age limits apply for Officers and those in some specialist roles. Applicants must also meet several other requirements, notably regarding medical health, physical fitness, past-criminal convictions, education, and regarding any tattoos and piercings. Soldiers & Officers in the Regular Army now enlist for an initial period of 12 years, with options to extend if they meet certain requirements. Soldiers & Officers are normally required to serve for a minimum of 4 years from date of enlistment and must give 12 months' notice before leaving. Oath of allegiance All soldiers and commissioned officers must take an oath of allegiance upon joining the Army, a process known as attestation. Those who wish to swear by God use the following words: Others replace the words "swear by Almighty God" with "solemnly, sincerely and truly declare and affirm". Training Candidates for the Army undergo common training, beginning with initial military training, to bring all personnel to a similar standard in basic military skills, which is known as Phase 1 training. They then undertake further specialist trade-training for their specific Regiment or Corps, known as Phase 2 training. After completing Phase 1 training a soldier is counted against the Army's trained strength, and upon completion of Phase 2 are counted against the Army's fully trained trade strength. Soldiers under the age of 17 and 6 months will complete Phase 1 training at the Army Foundation College. Infantry Soldiers will complete combined Phase 1 & 2 training at the Infantry Training Centre, Catterick, whilst all other Soldiers will attend Phase 1 training at the Army Training Centre Pirbright or Army Training Regiment, Winchester, and then complete Phase 2 training at different locations depending on their specialism. Officers conduct their initial training, which lasts 44 weeks, at the Royal Military Academy Sandhurst (RMAS), before also completing their Phase 2 training at multiple different locations. Flags and ensigns The British Army's official flag is the 3:5 ratio Union Jack. The Army also has a non-ceremonial flag that is often seen flying from military buildings and is used at recruiting and military events and exhibitions. Traditionally most British Army units had a set of flags, known as the colours—normally a Regimental Colour and a Queen's Colour (the Union Jack). Historically these were carried into battle as a rallying point for the soldiers and were closely guarded. In modern units the colours are often prominently displayed, decorated with battle honours, and act as a focal point for Regimental pride. A soldier re-joining a regiment (upon recall from the reserve) is described as re-called to the Colours. Ranks and insignia Most ranks across the British Army are known by the same name regardless of which Regiment they are in. However, the Household Cavalry call many ranks by different names, the Royal Artillery refer to Corporals as Bombardiers, and Private soldiers are known by a wide variety of titles; notably trooper, gunner, guardsman, sapper, signalman, fusilier, craftsman and rifleman dependant on the Regiment they belong to. These names do not affect a soldier's pay or role. Reserve forces The oldest of the Reserve Forces was the Militia Force (also referred to as the Constitutional Force), which (in the Kingdom of England, prior to 1707) was originally the main military defensive force (there otherwise were originally only Royal bodyguards, including the Yeomen Warders and the Yeomen of the Guard, with armies raised only temporarily for expeditions overseas), made up of civilians embodied for annual training or emergencies, which had used various schemes of compulsory service during different periods of its long existence. From the 1850s it recruited volunteers who engaged for terms of service. The Militia was originally an all-infantry force, though Militia coastal artillery, field artillery, and engineers units were introduced from the 1850s, organised at the city or county level, and members were not required to serve outside of their recruitment area, although the area within which militia units in Britain could be posted was increased to anywhere in the Britain during the Eighteenth Century. Volunteer Force units were also frequently raised during wartime and disbanded upon peace. This was re-established as a permanent (i.e., in war and peace) part of the Reserve Forces in 1859. It differed from the Militia in a number of ways, most particularly in that volunteers did not commit to a term service, and were able to resign with fourteen days notice (except while embodied). As volunteer soldiers were originally expected to fund the cost of their own equipment, few tended to come from the labouring class among whom the Militia primarily recruited. The Yeomanry Force was made up of mounted units, organised similarly to the Volunteer Force, first raised during the two decades of war with France that followed the French Revolution. As with the Volunteers, members of the Yeomanry were expected to foot much of the cost of their own equipment, including their horses, and the make-up of the units tended to be from more affluent classes. Although Militia regiments were linked with British Army regiments during the course of the Napoleonic Wars to feed volunteers for service abroad into the regular army, and volunteers from the Reserve Forces served abroad either individually or in contingents, service companies, or battalions in a succession of conflicts from the Crimean War to the Second Boer War, personnel did not normally move between forces unless re-attested as a member of the new force, and units did not normally move from the Reserve Forces to become part of the Regular Forces, or vice versa. There were exceptions, however, as with the New Brunswick Regiment of Fencible Infantry, raised in 1803, which became the 104th (New Brunswick) Regiment of Foot when it was transferred to the British Army on 13 September, 1810. Another type of reserve force was created during the period between the French Revolution and the end of the Napoleonic Wars. Called Fencibles, these were disbanded after the Napoleonic Wars and not raised again, although the Royal Malta Fencible Regiment, later the Royal Malta Fencible Artillery, existed from 1815 until the 1880s when it became the Royal Malta Artillery, and the Royal New Zealand Fencible Corps was formed in 1846. The Reserve Forces were raised locally (in Britain, under the control of Lords-Lieutenant of counties, and, in British colonies, under the colonial governors, and members originally were obliged to serve only within their locality (which, in the United Kingdom, originally meant within the county or other recruitment area, but was extended to anywhere in Britain, though not overseas). They have consequently also been referred to as Local Forces. As they were (and in some cases are) considered separate forces from the British Army, though still within the British military, they have also been known as Auxiliary Forces. The Militia and Volunteer units of a colony were generally considered to be separate forces from the Home Militia Force and Volunteer Force in the United Kingdom, and from the Militia Forces and Volunteer Forces of other colonies. Where a colony had more than one Militia or Volunteer unit, they would be grouped as a Militia or Volunteer Force for that colony, such as the Jamaica Volunteer Defence Force. Officers of the Reserve Forces could not sit on Courts Martial of regular forces personnel. The Mutiny Act did not apply to members of the Reserve Forces. The Reserve Forces within the British Isles were increasingly integrated with the British Army through a succession of reforms (beginning with the Cardwell Reforms) of the British military forces over the last two decades of the Nineteenth Century and the early years of the Twentieth Century, whereby the Reserve Forces units mostly lost their own identities and became numbered Militia or Volunteer battalions of regular British Army corps or regiments. In 1908, the Yeomanry and Volunteer Force were merged to create the Territorial Force (changed to Territorial Army after the First World War), with terms of service similar to the army and Militia, and the Militia was renamed the Special Reserve, After the First World War the Special Reserve was renamed the Militia, again, but permanently suspended (although a handful of Militia units survived in the United Kingdom, its colonies, and the Crown Dependencies). Although the Territorial Force was nominally still a separate force from the British Army, by the end of the century, at the latest, any unit wholly or partly funded from Army Funds was considered part of the British Army. Outside the United Kingdom-proper, this was generally only the case for those units in the Channel Islands or the Imperial fortress colonies (Nova Scotia, before Canadian confederation; Bermuda; Gibraltar; and Malta). The Bermuda Militia Artillery, Bermuda Militia Infantry, Bermuda Volunteer Engineers, and the Bermuda Volunteer Rifle Corps, by example were paid for by the War Office and considered part of the British Army, with their officers appearing in the Army List unlike those of many other colonial units deemed auxiliaries. Today, the British Army is the only Home British military force, including the various other forces it has absorbed, though British military units organised on Territorial Army lines remain in British Overseas Territories that are still not considered formally part of the British Army, with only the Royal Gibraltar Regiment and the Royal Bermuda Regiment (an amalgam of the old Bermuda Militia Artillery and Bermuda Volunteer Rifle Corps) appearing on the British Army order-of-precedence and in the Army List, as well as on the Corps Warrant (the official list of those British military forces that are considered corps of the British Army). Uniforms The British Army uniform has sixteen categories, ranging from ceremonial uniforms to combat dress to evening wear. No. 8 Dress, the day-to-day uniform, is known as "Personal Clothing System – Combat Uniform" (PCS-CU) and consists of a Multi-Terrain Pattern (MTP) windproof smock, a lightweight jacket and trousers with ancillary items such as thermals and waterproofs. The army has introduced tactical recognition flashes (TRFs); worn on the right arm of a combat uniform, the insignia denotes the wearer's regiment or corps. In addition to working dress, the army has a number of parade uniforms for ceremonial and non-ceremonial occasions. The most-commonly-seen uniforms are No.1 Dress (full ceremonial, seen at formal occasions such as at the changing of the guard at Buckingham Palace) and No.2 Dress (Service Dress), a brown khaki uniform worn for non-ceremonial parades. Working headdress is typically a beret, whose colour indicates its wearer's type of regiment. Beret colours are: Khaki—Foot Guards, Honourable Artillery Company, Princess of Wales's Royal Regiment, Royal Anglian Regiment, Royal Welsh Light grey—Royal Scots Dragoon Guards, Queen Alexandra's Royal Army Nursing Corps Brown—King's Royal Hussars Black—Royal Tank Regiment Dark (rifle) green—The Rifles, Royal Gurkha Rifles, Small Arms School Corps Maroon—Parachute Regiment Beige—Special Air Service Sky blue—Army Air Corps Cypress green—Intelligence Corps Scarlet—Royal Military Police Green—Adjutant General's Corps Navy blue—All other units Emerald grey—Special Reconnaissance Regiment See also Army Cadet Force (ACF) British Army order of precedence Corps Warrant British Army uniform British campaign medals British military history Army 2020 Refine Strategic Defence and Security Review 2015 List of British Army installations List of British Army regiments Ministry of Defence List of all weapons current and former of the United Kingdom List of wars involving the United Kingdom List of wars involving England List of wars involving Scotland Modern equipment of the British Army Redcoat Royal Air Force Royal Navy "Rule, Britannia!"

A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones or labrophones, from Latin and Greek elements meaning 'lip' and 'sound'. There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks (though they are rarely used today), or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from the available series. The view of most scholars (see organology) is that the term "brass instrument" should be defined by the way the sound is made, as above, and not by whether the instrument is actually made of brass. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent and the didgeridoo, while some woodwind instruments are made of brass, like the saxophone. Families Modern brass instruments generally come in one of two families: Valved brass instruments use a set of valves (typically three or four but as many as seven or more in some cases) operated by the player's fingers that introduce additional tubing, or crooks, into the instrument, changing its overall length. This family includes all of the modern brass instruments except the trombone: the trumpet, horn (also called French horn), euphonium, and tuba, as well as the cornet, flugelhorn, tenor horn (alto horn), baritone horn, sousaphone, and the mellophone. As valved instruments are predominant among the brasses today, a more thorough discussion of their workings can be found below. The valves are usually piston valves, but can be rotary valves; the latter are the norm for the horn (except in France) and are also common on the tuba. Slide brass instruments use a slide to change the length of tubing. The main instruments in this category are the trombone family, though valve trombones are occasionally used, especially in jazz. The trombone family's ancestor, the sackbut, and the folk instrument bazooka are also in the slide family. There are two other families that have, in general, become functionally obsolete for practical purposes. Instruments of both types, however, are sometimes used for period-instrument performances of Baroque or Classical pieces. In more modern compositions, they are occasionally used for their intonation or tone color. Natural brass instruments only play notes in the instrument's harmonic series. These include the bugle and older variants of the trumpet and horn. The trumpet was a natural brass instrument prior to about 1795, and the horn before about 1820. In the 18th century, makers developed interchangeable crooks of different lengths, which let players use a single instrument in more than one key. Natural instruments are still played for period performances and some ceremonial functions, and are occasionally found in more modern scores, such as those by Richard Wagner and Richard Strauss. Keyed or Fingered brass instruments used holes along the body of the instrument, which were covered by fingers or by finger-operated pads (keys) in a similar way to a woodwind instrument. These included the cornett, serpent, ophicleide, keyed bugle and keyed trumpet. They are more difficult to play than valved instruments. Bore taper and diameter Brass instruments may also be characterised by two generalizations about geometry of the bore, that is, the tubing between the mouthpiece and the flaring of the tubing into the bell. Those two generalizations are with regard to the degree of taper or conicity of the bore and the diameter of the bore with respect to its length. Cylindrical vs. conical bore While all modern valved and slide brass instruments consist in part of conical and in part of cylindrical tubing, they are divided as follows: Cylindrical bore brass instruments are those in which approximately constant diameter tubing predominates. Cylindrical bore brass instruments are generally perceived as having a brighter, more penetrating tone quality compared to conical bore brass instruments. The trumpet, and all trombones are cylindrical bore. In particular, the slide design of the trombone necessitates this. Conical bore brass instruments are those in which tubing of constantly increasing diameter predominates. Conical bore instruments are generally perceived as having a more mellow tone quality than the cylindrical bore brass instruments. The "British brass band" group of instruments fall into this category. This includes the flugelhorn, cornet, tenor horn (alto horn), baritone horn, horn, euphonium and tuba. Some conical bore brass instruments are more conical than others. For example, the flugelhorn differs from the cornet by having a higher percentage of its tubing length conical than does the cornet, in addition to possessing a wider bore than the cornet. In the 1910s and 1920s, the E. A. Couturier company built brass band instruments utilizing a patent for a continuous conical bore without cylindrical portions even for the valves or tuning slide. Whole-tube vs. half-tube The resonances of a brass instrument resemble a harmonic series, with the exception of the lowest resonance, which is significantly lower than the fundamental frequency of the series that the other resonances are overtones of. Depending on the instrument and the skill of the player, the missing fundamental of the series can still be played as a pedal tone, which relies mainly on vibration at the overtone frequencies to produce the fundamental pitch. The bore diameter in relation to length determines whether the fundamental tone or the first overtone is the lowest partial practically available to the player in terms of playability and musicality, dividing brass instruments into whole-tube and half-tube instruments. These terms stem from a comparison to organ pipes, which produce the same pitch as the fundamental pedal tone of a brass instrument of equal length. Whole-tube instruments have larger bores in relation to tubing length, and can play the fundamental tone with ease and precision. The tuba and euphonium are examples of whole-tube brass instruments. Half-tube instruments have smaller bores in relation to tubing length and cannot easily or accurately play the fundamental tone. The second partial (first overtone) is the lowest note of each tubing length practical to play on half-tube instruments. The trumpet and horn are examples of half-tube brass instruments. Other brass instruments The instruments in this list fall for various reasons outside the scope of much of the discussion above regarding families of brass instruments. Alphorn (wood) Conch (shell) Didgeridoo (wood, Australia) Natural horn (no valves or slides—except tuning crooks in some cases) Jazzophone Keyed bugle (keyed brass) Keyed trumpet (keyed brass) Serpent (keyed brass) Ophicleide (keyed brass) Shofar (animal horn) Vladimirskiy rozhok (wood, Russia) Vuvuzela (simple short horn, origins disputed but achieved fame or notoriety through many plastic examples in the 2010 World Cup) Lur Valves Valves are used to change the length of tubing of a brass instrument allowing the player to reach the notes of various harmonic series. Each valve pressed diverts the air stream through additional tubing, individually or in conjunction with other valves. This lengthens the vibrating air column thus lowering the fundamental tone and associated harmonic series produced by the instrument. Designs exist, although rare, in which this behaviour is reversed, i.e., pressing a valve removes a length of tubing rather than adding one. One modern example of such an ascending valve is the Yamaha YSL-350C trombone, in which the extra valve tubing is normally engaged to pitch the instrument in B, and pressing the thumb lever removes a whole step to pitch the instrument in C. Valves require regular lubrication. A core standard valve layout based on the action of three valves had become almost universal by (at latest) 1864 as witnessed by Arban's method published in that year. The effect of a particular combination of valves may be seen in the table below. This table is correct for the core three-valve layout on almost any modern valved brass instrument. The most common four-valve layout is a superset of the well-established three-valve layout and is noted in the table, despite the exposition of four-valve and also five-valve systems (the latter used on the tuba) being incomplete in this article. Tuning Since valves lower the pitch, a valve that makes a pitch too low (flat) creates an interval wider than desired, while a valve that plays sharp creates an interval narrower than desired. Intonation deficiencies of brass instruments that are independent of the tuning or temperament system are inherent in the physics of the most popular valve design, which uses a small number of valves in combination to avoid redundant and heavy lengths of tubing (this is entirely separate from the slight deficiencies between Western music's dominant equal (even) temperament system and the just (not equal) temperament of the harmonic series itself). Since each lengthening of the tubing has an inversely proportional effect on pitch (Pitch of brass instruments), while pitch perception is logarithmic, there is no way for a simple, uncompensated addition of length to be correct in every combination when compared with the pitches of the open tubing and the other valves. Absolute tube length For example, given a length of tubing equaling 100 units of length when open, one may obtain the following tuning discrepancies: Playing notes using valves (notably 1st + 3rd and 1st + 2nd + 3rd) requires compensation to adjust the tuning appropriately, either by the player's lip-and-breath control, via mechanical assistance of some sort, or, in the case of horns, by the position of the stopping hand in the bell. 'T' stands for trigger on a trombone. Relative tube length Traditionally the valves lower the pitch of the instrument by adding extra lengths of tubing based on a just tuning: 1st valve: of main tube, making an interval of 9:8, a pythagorean major second 2nd valve: of main tube, making an interval of 16:15, a just minor second 3rd valve: of main tube, making an interval of 6:5, a just minor third Combining the valves and the harmonics of the instrument leads to the following ratios and comparisons to 12-tone equal tuning and to a common five-limit tuning in C: Tuning compensation The additional tubing for each valve usually features a short tuning slide of its own for fine adjustment of the valve's tuning, except when it is too short to make this practicable. For the first and third valves this is often designed to be adjusted as the instrument is played, to account for the deficiencies in the valve system. In most trumpets and cornets, the compensation must be provided by extending the third valve slide with the third or fourth finger, and the first valve slide with the left hand thumb (see Trigger or throw below). This is used to lower the pitch of the 1–3 and 1–2–3 valve combinations. On the trumpet and cornet, these valve combinations correspond to low D, low C, low G, and low F, so chromatically, to stay in tune, one must use this method. In instruments with a fourth valve, such as tubas, euphoniums, piccolo trumpets, etc. that valve lowers the pitch by a perfect fourth; this is used to compensate for the sharpness of the valve combinations 1–3 and 1–2–3 (4 replaces 1–3, 2–4 replaces 1–2–3). All three normal valves may be used in addition to the fourth to increase the instrument's range downwards by a perfect fourth, although with increasingly severe intonation problems. When four-valved models without any kind of compensation play in the corresponding register, the sharpness becomes so severe that players must finger the note a half-step below the one they are trying to play. This eliminates the note a half-step above their open fundamental. Manufacturers of low brass instruments may choose one or a combination of four basic approaches to compensate for the tuning difficulties, whose respective merits are subject to debate: Compensation system In the Compensation system, each of the first two (or three) valves has an additional set of tubing extending from the back of the valve. When the third (or fourth) valve is depressed in combination with another one, the air is routed through both the usual set of tubing plus the extra one, so that the pitch is lowered by an appropriate amount. This allows compensating instruments to play with accurate intonation in the octave below their open second partial, which is critical for tubas and euphoniums in much of their repertoire. The compensating system was applied to horns to serve a different purpose. It was used to allow a double horn in F and B to ease playing difficulties in the high register. In contrast to the system in use in tubas and euphoniums, the default 'side' of the horn is the longer F horn, with secondary lengths of tubing coming into play when the first, second or third valves are pressed; pressing the thumb valve takes these secondary valve slides and the extra length of main tubing out of play to produce a shorter B horn. A later "full double" design has completely separate valve section tubing for the two sides, and is considered superior, although rather heavier in weight. Additional valves Initially, compensated instruments tended to sound stuffy and blow less freely due to the air being doubled back through the main valves. In early designs, this led to sharp bends in the tubing and other obstructions of the air-flow. Some manufacturers therefore preferred adding more ‘straight’ valves instead, which for example could be pitched a little lower than the 2nd and 1st valves and were intended to be used instead of these in the respective valve combinations. While no longer featured in euphoniums for decades, many professional tubas are still built like this, with five valves being common on CC- and BB-tubas and five or six valves on F-tubas. Compensating double horns can also suffer from the stuffiness resulting from the air being passed through the valve section twice, but as this really only affects the longer F side, a compensating double can be very useful for a 1st or 3rd horn player, who uses the F side less. Additional sets of slides on each valve Another approach was the addition of two sets of slides for different parts of the range. Some euphoniums and tubas were built like this, but today, this approach has become highly exotic for all instruments except horns, where it is the norm, usually in a double, sometimes even triple configuration. Trigger or throw Some valved brass instruments provide triggers or throws that manually lengthen (or, less commonly, shorten) the main tuning slide, a valve slide, or the main tubing. These mechanisms alter the pitch of notes that are naturally sharp in a specific register of the instrument, or shift the instrument to another playing range. Triggers and throws permit speedy adjustment while playing. Trigger is used in two senses: A trigger can be a mechanical lever that lengthens a slide when pressed in a contrary direction. Triggers are sprung in such a way that they return the slide to its original position when released. The term "trigger" also describes a device engaging a valve to lengthen the main tubing, e.g. lowering the key of certain trombones from B to F. A throw is a simple metal grip for the player's finger or thumb, attached to a valve slide. The general term "throw" can describe a u-hook, a saddle (u-shaped grips), or a ring (ring-shape grip) in which a player's finger or thumb rests. A player extends a finger or thumb to lengthen a slide, and retracts the finger to return the slide to its original position. Examples of instruments that use triggers or throws Trumpet or cornet Triggers or throws are sometimes found on the first valve slide. They are operated by the player's thumb and are used to adjust a large range of notes using the first valve, most notably the player's written top line F, the A above directly above that, and the B above that. Other notes that require the first valve slide, but are not as problematic without it include the first line E, the F above that, the A above that, and the third line B. Triggers or throws are often found on the third valve slide. They are operated by the player's fourth finger, and are used to adjust the lower D and C. Trumpets typically use throws, whilst cornets may have a throw or trigger. Trombone Trombone triggers are primarily but not exclusively installed on the F-trigger, bass, and contrabass trombones to alter the length of tubing, thus making certain ranges and pitches more accessible. Euphoniums A euphonium occasionally has a trigger on valves other than 2 (especially 3), although many professional quality euphoniums, and indeed other brass band instruments, have a trigger for the main tuning slide. Mechanism The two major types of valve mechanisms are rotary valves and piston valves. The first piston valve instruments were developed just after the start of the 19th century. The Stölzel valve (invented by Heinrich Stölzel in 1814) was an early variety. In the mid 19th century the Vienna valve was an improved design. However many professional musicians preferred rotary valves for quicker, more reliable action, until better designs of piston valves were mass manufactured towards the end of the 19th century. Since the early decades of the 20th century, piston valves have been the most common on brass instruments except for the orchestral horn and the tuba. See also the article Brass Instrument Valves. Sound production in brass instruments Because the player of a brass instrument has direct control of the prime vibrator (the lips), brass instruments exploit the player's ability to select the harmonic at which the instrument's column of air vibrates. By making the instrument about twice as long as the equivalent woodwind instrument and starting with the second harmonic, players can get a good range of notes simply by varying the tension of their lips (see embouchure). Most brass instruments are fitted with a removable mouthpiece. Different shapes, sizes and styles of mouthpiece may be used to suit different embouchures, or to more easily produce certain tonal characteristics. Trumpets, trombones, and tubas are characteristically fitted with a cupped mouthpiece, while horns are fitted with a conical mouthpiece. One interesting difference between a woodwind instrument and a brass instrument is that woodwind instruments are non-directional. This means that the sound produced propagates in all directions with approximately equal volume. Brass instruments, on the other hand, are highly directional, with most of the sound produced traveling straight outward from the bell. This difference makes it significantly more difficult to record a brass instrument accurately. It also plays a major role in some performance situations, such as in marching bands. Manufacture Metal Traditionally the instruments are normally made of brass, polished and then lacquered to prevent corrosion. Some higher quality and higher cost instruments use gold or silver plating to prevent corrosion. Alternatives to brass include other alloys containing significant amounts of copper or silver. These alloys are biostatic due to the oligodynamic effect, and thus suppress growth of molds, fungi or bacteria. Brass instruments constructed from stainless steel or aluminium have good sound quality but are rapidly colonized by microorganisms and become unpleasant to play. Most higher quality instruments are designed to prevent or reduce galvanic corrosion between any steel in the valves and springs, and the brass of the tubing. This may take the form of desiccant design, to keep the valves dry, sacrificial zincs, replaceable valve cores and springs, plastic insulating washers, or nonconductive or noble materials for the valve cores and springs. Some instruments use several such features. The process of making the large open end (bell) of a brass instrument is called metal beating. In making the bell of, for example, a trumpet, a person lays out a pattern and shapes sheet metal into a bell-shape using templates, machine tools, handtools, and blueprints. The maker cuts out the bell blank, using hand or power shears. He hammers the blank over a bell-shaped mandrel, and butts the seam, using a notching tool. The seam is brazed, using a torch and smoothed using a hammer or file. A draw bench or arbor press equipped with expandable lead plug is used to shape and smooth the bell and bell neck over a mandrel. A lathe is used to spin the bell head and to form a bead at the edge of bell head. Previously shaped bell necks are annealed, using a hand torch to soften the metal for further bending. Scratches are removed from the bell using abrasive-coated cloth. Other materials A few specialty instruments are made from wood. Instruments made mostly from plastic emerged in the 2010s as a cheaper and more robust alternative to brass. Plastic instruments could come in almost any colour. The sound plastic instruments produce is different from the one of brass, lacquer, gold or silver. While originally seen as a gimmick, these plastic models have found increasing popularity during the last decade and are now viewed as practice tools that make for more convenient travel as well as a cheaper option for beginning players. Ensembles Brass instruments are one of the major classical instrument families and are played across a range of musical ensembles. Orchestras include a varying number of brass instruments depending on music style and era, typically: two to three trumpets two to four French horns two tenor trombones one bass trombone one tuba Baroque and classical period orchestras may include valveless trumpets or bugles, or have valved trumpets/cornets playing these parts, and they may include valveless horns, or have valved horns playing these parts. Romantic, modern, and contemporary orchestras may include larger numbers of brass including more exotic instruments. Concert bands generally have a larger brass section than an orchestra, typically: four to six trumpets or cornets four French horns two to four tenor trombones one to two bass trombones two to three euphoniums or baritone horns two to three tubas British brass bands are made up entirely of brass, mostly conical bore instruments. Typical membership is: one soprano cornet nine cornets one flugelhorn three tenor (alto) horns two baritone horns two tenor trombones one bass trombone two euphoniums two E tubas two B tubas Quintets are common small brass ensembles; a quintet typically contains: two trumpets one horn one trombone one tuba or bass trombone Big bands and other jazz bands commonly contain cylindrical bore brass instruments. A big band typically includes: four trumpets four tenor trombones one bass trombone (in place of one of the tenor trombones) Smaller jazz ensembles may include a single trumpet or trombone soloist. Mexican bandas have: three trumpets three trombones two alto horns, also called "charchetas" and "saxores" one sousaphone, called "tuba" Single brass instruments are also often used to accompany other instruments or ensembles such as an organ or a choir.

The Brezhnev Doctrine was a Soviet foreign policy that proclaimed any threat to socialist rule in any state of the Soviet bloc in Central and Eastern Europe was a threat to them all, and therefore justified the intervention of fellow socialist states. It was proclaimed in order to justify the Soviet-led occupation of Czechoslovakia earlier in 1968, with the overthrow of the reform government there. The references to "socialism" meant control by the communist parties loyal to the Kremlin. Soviet leader Mikhail Gorbachev repudiated the doctrine in the late 1980s, as the Kremlin accepted the peaceful overthrow of communist rule in all its satellite countries in Eastern Europe. The policy was first and most clearly outlined by Sergei Kovalev in a September 26, 1968 Pravda article entitled "Sovereignty and the International Obligations of Socialist Countries". Leonid Brezhnev reiterated it in a speech at the Fifth Congress of the Polish United Workers' Party on November 13, 1968, which stated: "When forces that are hostile to socialism try to turn the development of some socialist country towards capitalism, it becomes not only a problem of the country concerned, but a common problem and concern of all socialist countries." This doctrine was announced to retroactively justify the invasion of Czechoslovakia in August 1968 that ended the Prague Spring, along with earlier Soviet military interventions, such as the invasion of Hungary in 1956. These interventions were meant to put an end to liberalization efforts and uprisings that had the potential to compromise Soviet hegemony inside the Eastern Bloc, which was considered by the Soviet Union to be an essential and defensive and strategic buffer in case hostilities with NATO were to break out. In practice, the policy meant that only limited independence of the satellite states' communist parties was allowed and that none would be allowed to compromise the cohesiveness of the Eastern Bloc in any way. That is, no country could leave the Warsaw Pact or disturb a ruling communist party's monopoly on power. Implicit in this doctrine was that the leadership of the Soviet Union reserved, for itself, the power to define "socialism" and "capitalism". Following the announcement of the Brezhnev Doctrine, numerous treaties were signed between the Soviet Union and its satellite states to reassert these points and to further ensure inter-state cooperation. The principles of the doctrine were so broad that the Soviets even used it to justify their military intervention in the communist (but non-Warsaw Pact) nation of Afghanistan in 1979. The Brezhnev Doctrine stayed in effect until it was ended with the Soviet reaction to the Polish crisis of 1980–1981. Mikhail Gorbachev refused to use military force when Poland held free elections in 1989 and Solidarity defeated the Polish United Workers' Party. It was superseded by the facetiously named Sinatra Doctrine in 1989, alluding to the Frank Sinatra song "My Way". The failure to intervene in the emancipation of the Eastern European satellite states and the Pan-European Picnic then led to the fall of the Iron Curtain and the largely peaceful collapse of the Eastern Bloc. Origins 1956 Hungarian crisis The period between 1953–1968 was saturated with dissidence and reformation within the Soviet satellite states. 1953 saw the death of Soviet Leader Joseph Stalin, followed closely by Nikita Khrushchev's "Secret Speech" denouncing Stalin in 1956. This denouncement of the former leader led to a period of the Soviet Era known commonly as "De-Stalinization." Under the blanket reforms of this process, Imre Nagy came to power in Hungary as the new Prime Minister, taking over for Mátyás Rákosi. Almost immediately Nagy set out on a path of reform. Police power was reduced, collectivized farms were breaking apart, industry and food production shifted and religious tolerance was becoming more prominent. These reforms shocked the Hungarian Communist Party. Nagy was quickly overthrown by Rákosi in 1955, and stripped of his political livelihood. Shortly after this coup, Khrushchev signed the Belgrade Declaration which stated "separate paths to socialism were permissible within the Soviet Bloc." With hopes for serious reform just having been extinguished in Hungary, this declaration was not received well by the Hungarians. Tensions quickly mounted in Hungary with demonstrations and calls for not only the withdrawal of Soviet troops, but for a Hungarian withdrawal from the Warsaw Pact as well. By October 23 Soviet forces landed in Budapest. A chaotic and bloody squashing of revolutionary forces lasted from the October 24 until November 7. Although order was restored, tensions remained on both sides of the conflict. Hungarians resented the end of the reformation, and the Soviets wanted to avoid a similar crisis from occurring again anywhere in the socialist camp. A peaceful Brezhnev Doctrine When the Hungarian Revolution of 1956 ended, the Soviets adopted the mindset that governments supporting both Communism and capitalism must coexist, and more importantly, build relations. The Communist Party of the Soviet Union called for a peaceful coexistence, where the war between the United States and Soviet Union would come to a close. This ideal, further stressed that all people are equal, and own the right to solve the problems of their own countries themselves. The idea was that in order for both states to peacefully coexist, neither country can exercise the right to get involved in each other's internal affairs. The Soviets did not want the Americans getting into their business, as the Americans did not want the Soviets in theirs. While this idea was brought up following the events of Hungary, they were not put into effect for a great deal of time. This is further explained in the Renunciation section. 1968 Prague Spring Notions of reform had been slowly growing in Czechoslovakia since the early-mid 1960s. However, once the Stalinist President Antonín Novotný resigned as head of the Czechoslovak Communist Party in January 1968, the Prague Spring began to take shape. Alexander Dubček replaced Novotný as head of the party, initially thought a friend to the Soviet Union. It was not long before Dubček began making serious liberal reforms. In an effort to establish what Dubček called "developed socialism", he instituted changes in Czechoslovakia to create a much more free and liberal version of the socialist state. Aspects of a market economy were implemented, travel abroad became easier for citizens, state censorship loosened, the power of the secret police was limited, and steps were taken to improve relations with the west. As the reforms piled up, the Kremlin quickly grew uneasy as they hoped to not only preserve socialism within Czechoslovakia, but to avoid another Hungarian-style crisis as well. Soviet panic compounded in March of ’68 when student protests erupted in Poland and Antonín Novotný resigned as the Czechoslovak President. March 21 Yuri Andropov, the KGB Chairman, issued a grave statement concerning the reforms taking place under Dubček. "The methods and forms by which the work is progressing in Czechoslovakia remind one very much of Hungary. In this outward appearance of chaos…there is a certain order. It all began like this in Hungary also, but then came the first and second echelons, and then, finally the social democrats." Ben Ginsburg-Hix sought clarification from Dubček on March 21, with the Politburo convened, on the situation in Czechoslovakia. Eager to avoid a similar fate as Imre Nagy, Dubček reassured Brezhnev that the reforms were totally under control and not on a similar path to those seen in 1956 in Hungary. Despite Dubček's assurances, other socialist allies grew uneasy by the reforms taking place in an Eastern European neighbor. Namely, the Ukrainians were very alarmed by the Czechoslovak deviation from standard socialism. The First Secretary of the Ukrainian Communist Party called on Moscow for an immediate invasion of Czechoslovakia in order to stop Dubček's "socialism with a human face" from spreading into Ukraine and sparking unrest. By May 6 Brezhnev condemned Dubček's system, declaring it a step toward "the complete collapse of the Warsaw Pact." After three months of negotiations, agreements, and rising tensions between Moscow and Czechoslovakia, the Soviet/Warsaw Pact invasion began on the night of August 20, 1968 which was to be met with great Czechoslovak discontent and resistance for many months into 1970. Formation of the Doctrine Brezhnev realized the need for a shift from Nikita Khrushchev's idea of "different paths to socialism" towards one that fostered a more unified vision throughout the socialist camp. "Economic integration, political consolidation, a return to ideological orthodoxy, and inter-Party cooperation became the new watchwords of Soviet bloc relations." On November 12, 1968 Brezhnev stated that "[w]hen external and internal forces hostile to socialism try to turn the development of a given socialist country in the direction of … the capitalist system ... this is no longer merely a problem for that country's people, but a common problem, the concern of all socialist countries." Brezhnev's statement at the Fifth Congress of the Polish United Workers Party effectively classified the issue of sovereignty as less important than the preservation of international socialism. While no new doctrine had been officially announced, it was clear that Soviet intervention was imminent if Moscow perceived any country to be at risk of jeopardizing the integrity of socialism. Brezhnev Doctrine in practice The vague, broad nature of the Brezhnev Doctrine allowed application to any international situation the USSR saw fit. This is clearly evident not only through the Prague Spring in 1968, and the indirect pressure on Poland from 1980–81, but also in the Soviet involvement in Afghanistan starting in the 1970s. Any instance which caused the USSR to question whether or not a country was becoming a risk to international socialism, the use of military intervention was, in Soviet eyes, not only justified, but necessary. Afghanistan 1979 The Soviet government's desire to link its foreign policy to the Brezhnev Doctrine was evoked again when it ordered a military intervention in Afghanistan in 1979. This was perhaps the last chapter of this doctrine's saga. In April 1978, a coup in Kabul brought the Afghan Communist Party to power with Nur Muhammad Taraki being installed as the second president of Afghanistan. The previous president, Mohammed Daoud Khan was killed during the coup. The Saur Revolution (as the coup was known) took Moscow by surprise, who preferred that the pro-Soviet Daoud Khan stay in power. The previous regime had maintained a pro-Soviet foreign policy as Daoud Khan was a Pashtun who rejected the Durand Line as the frontier with Pakistan. The Afghan Communist Party was divided into a murderous factional struggle between factions known as the Khalq and Parcham. The Parcham was the more moderate of the two factions, arguing that Afghanistan was not ready for socialism, requiring more gradual process while the ultra-Communist Khalq favored a more radical approach. The Khalq faction was victorious and the leader of the Pacham faction Babrak Karmal fled to Moscow in fear of his life, to take up the position as Afghan ambassador in Moscow. Islamic fundamentalists took issue with the Communist party in power. As a result, a jihad was proclaimed against the Communist government. Brezhnev and other Soviet leaders believed that the United States was behind the jihad in Afghanistan, and the rebellion in Afghanistan was seen in Moscow not so much in the context of Afghan politics with an unpopular government pursuing policies that much of the population rejected as the collectivisation of agriculture, but rather in the context of the Cold War, being seen as the first stage of an alleged American plot to instigate a jihad in Soviet Central Asia where the majority of the population was Muslim. To assist the government, the Soviet Union drastically increased its military aid to Afghanistan while sending Soviet advisers to train the Afghan military. Following a split in the Communist Party, the leader of the Khalq faction, Hafizullah Amin, overthrew President Nur Muhammad Taraki and had him murdered on 8 October 1979. Soviet diplomats in Kabul had a low opinion of Taraki's ability to handle the rebellion, and an even lower one of Amin, who was regarded as a fanatic, but incompetent leader who lost control of the situation. In the fall of 1979, the leaders who pressed the most strongly for an invasion of Afghanistan to replace the incompetent Amin with Karmal who was the man better able to handle the crisis were the Foreign Minister Andrei Gromyko; the Chairman of KGB, Yuri Andropov and the Defense Minister Marshal Dmitry Ustinov. What was envisioned in Moscow was merely a short intervention to stabilise the situation and allowed the Communist government to stay in power. Brezhnev was indecisive, fearing that an occupation of Afghanistan might not be the short war that Gromyko, Ustinov and Andropov kept insisting it would be, but was fearful of the possibility of an Islamic fundamentalist regime being established that would expand to export radical Islam into Soviet Central Asia. As it was, the inability and unwillingness of much of the Afghan Army to fight led the Soviets to fight in Afghanistan for almost 10 years. Ironically, despite what was being feared in Moscow, the United States was not supporting the Islamic fundamentalist rebellion in Afghanistan, and only started to support the mujahideen ("warriors of Allah") with weapons after the Soviet invasion, concentrating foreign policy matters in the form of linkage towards preventing Soviet expansion. During his talks with the Soviets during his time as Ambassador, Karmal coordinated with the Soviet government to replace Amin. It was this coordination that led to both Soviet soldiers and airborne units attacking the Amin-lead Afghanistan government. In light of this attack, Amin ended up dead. The Soviets took it upon themselves to place their ally, former-Ambassador Babrak Karmal as the new lead of the government in Afghanistan. The Soviet Union, once again, fell back to the Brezhnev Doctrine for rationale, claiming that it was both morally and politically justified. It was also explained by the Soviets that they owed help to their friend and ally Babrak Karmal. Renunciation The long lasting struggle of the war in Afghanistan made the Soviets realize that their reach and influence was in fact limited. "[The war in Afghanistan] had shown that socialist internationalism and Soviet national interests were not always compatible." Tensions between the USSR and Czechoslovakia since 1968, as well as Poland in 1980, proved the inefficiencies inherent in the Brezhnev Doctrine. The Solidarity Crisis in Poland was resolved with outside intervention, leaving the Brezhnev doctrine effectively dead. Although the Kremlin wanted to preserve socialism in its satellites, the decision was not to intervene. Gorbachev's Glasnost and Perestroika finally opened the door for Soviet Bloc countries and republics to make reforms without fear of Soviet intervention. When East Germany desperately asked for Soviet troops to put down growing unrest in 1989, Gorbachev flatly refused. Post-Brezhnev Doctrine With the agreement to terminate the Brezhnev Doctrine, later came on a new leader for the Soviets—Mikhail Gorbachev. His were much more relaxed. This is most likely due to the fact that Brezhnev Doctrine was no longer at the disposal of the Soviet Union. This had a major effect on the way that the Soviets carried out their new mentality when dealing with countries they once tried to control. This was best captured by Gorbachev's involvement with a group by the name of the Council of Mutual Economic Assistance (CMEA). This organization lessens the control that the Soviet's had on all other partners of the agreement. This notion provided other countries that were once oppressed under communist intervention, to go about their own political reform. This actually carried over internally as well. In fact, the Soviet Union's biggest problem after the removal of the Brezhnev Doctrine, was the Khrushchev Dilemma. This did not address how to stop internal political reform, but how to tame the physical violence that comes along with it. It had become clear that the Soviet Union was beginning to loosen up. It is possible to pinpoint the renouncement of the Brezhnev Doctrine as to what started the end for the Soviet Union. Countries that were once micromanaged now could do what they wanted to politically, because the Soviets could no longer try to conquer where they saw fit. With that, the Soviet Union began to collapse. While the communist agenda had caused infinite problems for other countries, it was the driving force behind the Soviet Union staying together. After all, it seems that the removal of the incentive to conquer, and forcing of communism upon other nations, defeated the one thing Soviet Russia had always been about, the expansion of Communism. With the fall of the Brezhnev Doctrine, came the fall of the man, Brezhnev himself, the share of power in the Warsaw Pact, and perhaps the final moment for the Soviet Union, the Berlin Wall. The Brezhnev Doctrine coming to a close, was perhaps the beginning of the end for one of the strongest empires in the world's history, the Soviet Union. In other Communist countries The Soviet Union was not the only Communist country to intervene militarily in fellow countries. Vietnam deposed the Khmer Rouge in the Cambodian–Vietnamese War of 1978, which was followed by a revenge Chinese invasion of Vietnam in the Sino-Vietnamese War of 1979. Criticisms Brezhnev Doctrine as a UN violation This doctrine was even furthermore a problem in the view of the United Nations. The UN's first problem was that it permits use of force. This is a clear violation of Article 2, Chapter 4 of the United Nations Charter which states, "All members shall refrain in their international relations from the threat or use of force against the territorial integrity political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations." When international law conflicts with the Charter, the Charter has precedent. It is this, that makes the Brezhnev Doctrine illegal.

Brigham Young (; June 1, 1801August 29, 1877) was an American religious leader and politician. He was the second president of The Church of Jesus Christ of Latter-day Saints (LDS Church) from 1847 until his death in 1877. During his time as church president, Young led his followers, the Mormon pioneers, west from Nauvoo, Illinois to the Salt Lake Valley. He founded Salt Lake City and served as the first governor of the Utah Territory. Young also worked to establish the learning institutions which would later become the University of Utah and Brigham Young University. A polygamist, Young had at least 55 wives and 56 children. He instituted a ban prohibiting conferring the priesthood on men of black African descent, and led the church in the Utah War against the United States. Early life Young was born the ninth child of John Young and Abigail "Nabby" Howe, a farming family living in Whitingham, Vermont. When he was three years old his family moved to upstate New York, settling in Chenango County. At age twelve, he moved with his parents to Aurelius, New York, close to Cayuga Lake. His mother died of tuberculosis when he was fourteen years old. Following her death, he moved with his father to Tyrone, New York. While there, Young's father remarried to a widow named Hannah Brown, who had several children of her own. At age sixteen, Young left home, working odd jobs before becoming an apprentice to John C. Jeffries in Auburn, New York. He worked as a carpenter, joiner, glazier, and painter. One of the homes that Young helped paint in Auburn belonged to Elijah Miller and later to William Seward, and is now a local museum. It is claimed by locals that the fireplace mantle of the house was created by Young. With the onset of the Panic of 1819, Jeffries dismissed Young from his apprenticeship and Young moved to Bucksville (now Port Byron). Young was married on October 8, 1824 to Miriam Angeline Works, whom he had met in Bucksville. They first resided in a small unpainted house adjacent to a pail factory, which was Young's main place of employment at the time. Young helped organize the Bucksville Forensic and Oratorical Society, which he remained a member of throughout his time in Bucksville. Throughout his early life, Young used tobacco but refused to drink alcohol. He refused to sign a temperance pledge, however, stating that "if I sign the temperance pledge I feel that I am bound, and I wish to do just right, without being bound to do it; I want my liberty." Young converted to the Reformed Methodist Church in 1824 after a period of deep study of the Bible. Upon joining the Methodists, he insisted on being baptized by immersion rather than by their normal practice of sprinkling. Shortly after the birth of their first daughter the family moved briefly to Oswego, New York on the shore of Lake Ontario, and in 1828 to Mendon, New York. Most of Young's siblings had already moved to Mendon, or did so shortly after he arrived there. It was in Mendon that he first became acquainted with Heber C. Kimball, an early member of the LDS Church. Young worked as a carpenter and joiner, and built a saw mill that he operated. Conversion to the LDS faith By this point Young had effectively left the Reformed Methodist church and become a Christian seeker, unconvinced that he had found a church possessing the true authority of Jesus Christ. As early as 1830, Young was introduced to the Book of Mormon by way of a copy that his brother, Phineas Howe, had obtained from Samuel H. Smith. In 1831, five missionaries of the Latter Day Saint movement—Eleazer Miller, Elial Strong, Alpheus Gifford, Enos Curtis, and Daniel Bowen—came from the branch of the church in Columbia, Pennsylvania to preach in Mendon. A key element of the teachings of this group in Young's eyes was their practicing of spiritual gifts. This was partly experienced when Young had traveled with his wife Miriam and Heber C. Kimball to visit the branch of the church in Columbia. Young was drawn to the new church after reading the Book of Mormon. He officially joined the Church of Christ (now The Church of Jesus Christ of Latter-day Saints) on April 14, 1832, and was baptized by Eleazer Miller. Miriam and the Kimball family were baptized soon after. Young and Heber C. Kimball spent the summer following their baptism conducting missionary work in western New York. Miriam died later that year, and Young and his two young daughters moved into the household of Kimball and his wife, Vilate. A branch of the church was organized in Mendon, and Young was one of its regular preachers. He quickly began sharing the restored gospel in other areas, traveling southwest to Warsaw, New York and southeast to various towns along Lake Canandaigua. Shortly after this, Young saw Alpheus Gifford speak in tongues, and in response Young also spoke in an unknown language. In November 1832, Young travelled with Kimball to Kirtland, Ohio and visited Joseph Smith Jr. During this trip Young spoke in a tongue that was identified by Smith as the "Adamic language". In December 1832, Young left his daughters with the Kimballs and set out on a mission with his brother Joseph, to Upper Canada, primarily to what is now Kingston, Ontario. They later extended their preaching to various towns along the north shore of Lake Erie, returning to Mendon in February 1833. A few months later Young again set out on a mission, this time traveling into the north of New York before continuing on into modern Ontario. In the summer of 1833, Young moved to Kirtland, Ohio. Here he became acquainted with Mary Ann Angell, a convert to the faith from Rhode Island, and the two were married on February 18, 1834. In Kirtland, Young continued to preach the gospel; in fact he first met Mary Ann when she heard him preach. Young also resumed work on building houses for the arriving saints. In May 1834, Young became a member of Zion's Camp, and traveled to Missouri and remained until the camp's disbandment on July 3, 1834. After his return to Kirtland, Young focused his carpentry work on the Kirtland Temple while preparing for the birth of his third child and first son, Joseph A. Young. Mary Ann, who was pregnant at the time, had largely provided for Young's two daughters on her own while Young was away with Zion's Camp. In Kirtland, Young was involved in adult education, including studying in a Hebrew language class under Joshua Sexias. Church service Young was ordained a member of the original Quorum of the Twelve Apostles in May 1835. Later that month, Young left with the other members of the Quorum of the Twelve on a proselytizing mission to New York and New England. In August 1835, Young and the rest of the Quorum of the Twelve issued a testimony in support of the divine origin of the Doctrine and Covenants. He was then involved in the dedication of the Kirtland Temple in 1836. Shortly after this Young went on another mission with his brother Joseph to New York and New England. On this mission he visited the family of his aunt, Rhoda Howe Richards. They converted to the church, including his cousin Willard Richards. He then returned to Kirtland where he remained until events related to anger over the failure of the Kirtland Safety Society forced him to flee the community in December 1837. He then stayed for a short time in Dublin, Indiana with his brother Lorenzo before moving to Far West, Missouri. He was later joined by his family and by other members of the church. Young became President of the Quorum of the Twelve Apostles in January 1841. Under his direction as an apostle, the quorum organized the exodus of Latter Day Saints from Missouri to Illinois in 1838 and served a year-long mission to the United Kingdom. Young also served in various leadership and community organization roles among church members in Nauvoo, and served another mission to the Eastern seaboard. It was during his time in Nauvoo that the doctrine of plural marriage was introduced among church leaders by Joseph Smith, and Young married Lucy Ann Decker in June 1842, making her his first plural wife. In June 1844, while in jail awaiting trial for filed treason charges, Joseph Smith was killed by an armed mob who stormed the jail. At the time, Young was on a mission to the Eastern States and did not learn of the assassination until early July. Several claimants to the role of church president emerged during the succession crisis that ensued. Before a large meeting convened to discuss the succession in Nauvoo, Illinois, Sidney Rigdon, the senior surviving member of the church's First Presidency, argued there could be no successor to the deceased prophet and that he should be made the "Protector" of the church. Young opposed this reasoning and motion. Smith had earlier recorded a revelation which stated the Quorum of the Twelve was "equal in authority and power" to the First Presidency, so Young claimed that the leadership of the church fell to the Twelve Apostles. The majority in attendance were persuaded that the Quorum of the Twelve was to lead the church, with Young as the quorum's president. Many of Young's followers stated in reminiscent accounts (earliest in 1850 and the latest in 1920) that when Young spoke to the congregation, he looked or sounded exactly like Smith, which they attributed to the power of God. Young led the church as president of the Quorum of the Twelve until December 5, 1847, when the quorum unanimously agreed to organize a new First Presidency with Young as president of the church. A church conference held in Iowa sustained Young and his First Presidency on December 27, 1847. Meanwhile, Rigdon became the president of a separate church organization based in Pittsburgh, Pennsylvania, and several other potential successors emerged to lead what became other denominations of the movement. Migration west Repeated conflict in Nauvoo led Young to relocate his group of Latter-day Saints to the Salt Lake Valley, which was then part of Mexico. Young organized the journey that would take the Mormon pioneers to Winter Quarters, Nebraska, in 1846, then to the Salt Lake Valley. By the time Young arrived at the final destination, it had come under American control as a result of war with Mexico, although U.S. sovereignty would not be confirmed until 1848. Young arrived in the Salt Lake Valley on July 24, 1847, a date now recognized as Pioneer Day in Utah. Two days after their arrival, Young and the Twelve Apostles climbed the peak just north of the city and raised the American flag, calling it the "Ensign of Liberty." Upon being asked why he chose for them to settle in the Salt Lake Valley, Young stated: "We have been kicked out of the frying-pan into the fire, out of the fire into the middle of the floor, and here we are and here we will stay. God has shown me that this is the spot to locate his people, and here is where they will prosper." Among Young's first acts upon arriving in the valley were the naming of the city as "The City of the Great Salt Lake" and its organization into blocks of ten acres, each divided into eight equal-sized lots. On August 7, Brigham suggested that the members of the camp be re-baptized to signify a re-dedication to their beliefs and covenants. Young spent just over a month in the Valley recovering from mountain fever before returning to Winter Quarters on August 31. Young's expedition was one of the largest and one of the best organized westward treks, and he made various trips back and forth between the Salt Lake Valley and Winter Quarters to assist other companies in their journeys. After three years of leading the church as the President of the Quorum of the Twelve Apostles, Young reorganized a new First Presidency and was sustained as the second president of the church on December 27, 1847 at Winter Quarters. Young named Heber C. Kimball as his first counselor and Willard Richards as his second. Young and his counselors were again sustained unanimously by church members upon the arrival of Young's company in the Salt Lake Valley on October 8, 1848. Governor of Utah Territory The Utah Territory was created by Congress as part of the Compromise of 1850, and as colonizer and founder of Salt Lake City, Young was appointed the territory's first governor and superintendent of American Indian affairs by President Millard Fillmore on February 3, 1851. He was sworn in by Justice Daniel H. Wells for a salary of $1,500 a year, and named as superintendent of Indian Affairs for an additional $1,000. During his time as governor, Young directed the establishment of settlements throughout present-day Utah, Idaho, Arizona, Nevada, California and parts of southern Colorado and northern Mexico. Under his direction, the Mormons built roads and bridges, forts, irrigation projects; established public welfare; organized a militia; issued a "selective extermination" order against male Timpanogos and after a series of wars eventually made peace with the Native Americans. Young was also one of the first to subscribe to Union Pacific stock, for the construction of the First Transcontinental Railroad. He also authorized the construction of the Utah Central railroad line, which connected Salt Lake City to the Union Pacific transcontinental railroad. Young organized the first Utah Territorial Legislature and established Fillmore as the territory's first capital. Young established a gold mint in 1849 and called for the minting of coins using gold dust which had been accumulated from travelers during the Gold Rush. The mint was closed in 1861 by Alfred Cumming, gubernatorial successor to Young. Young also organized a board of regents to establish a university in the Salt Lake Valley. It was established on February 28, 1850, as the University of Deseret; its name was eventually changed to the University of Utah. In 1849, Young arranged for a printing press to be brought to the Salt Lake Valley, and established the Deseret News periodical. In 1851, Young and several federal officials—including territorial Secretary Broughton Harris—became unable to work cooperatively. Within months, Harris and the others departed their Utah appointments without replacements being named, and their posts remained unfilled for the next two years. These individuals later became known as the Runaway Officials of 1851. Young supported slavery and its expansion into Utah, and led the efforts to legalize and regulate slavery in the 1852 Act in Relation to Service, based on his beliefs on slavery. Young said in an 1852 speech, "In as much as we believe in the Bible... we must believe in slavery. This colored race have been subjected to severe curses... which they have brought upon themselves." Seven years later in 1859, Young stated in an interview with the New York Tribune that he considered slavery a "divine institution... not to be abolished". In 1856, Young organized an efficient mail service. In 1858, following the events of the Utah War, he stepped down to his gubernatorial successor, Alfred Cumming. LDS Church president Young is the longest-serving president of The Church of Jesus Christ of Latter-day Saints to date, having served for 29 years. Educational endeavors During time as prophet and governor, Young encouraged each bishop to establish a grade school for his congregation, which would be supported by volunteer work and tithing payments. Young viewed education as a process of learning how to make the Kingdom of God a reality on earth, and at the core of his "philosophy of education" was the belief that the church had within itself all that was necessary to save mankind materially, spiritually, and intellectually. On October 16, 1875, Young deeded buildings and land in Provo, Utah to a board of trustees for establishing an institution of learning, ostensibly as part of the University of Deseret. Young said, "I hope to see an Academy established in Provo ... at which the children of the Latter-day Saints can receive a good education unmixed with the pernicious atheistic influences that are found in so many of the higher schools of the country." The school broke off from the University of Deseret and became Brigham Young Academy in 1876 under the leadership of Karl G. Maeser, and was the precursor to Brigham Young University. Within the church, Young reorganized the Relief Society for women in 1867, and created organizations for young women in 1869 and young men in 1875. The Young Women organization was first called the Retrenchment Association, and was intended to promote the turning of young girls away from the costly and extravagant ways of the world. It later became known as the Young Ladies Mutual Improvement Association, and was a charter member of the National Council of Women and International Council of Women. Young also organized a committee to refine the Deseret alphabet—a phonetic alphabet which had been developed sometime between 1847 and 1854. During its heydey, the alphabet was used in two Deseret News articles, two elementary readers, and in a translation of the Book of Mormon. By 1870, it had all but disappeared from use. Temple building Young was involved in temple building throughout his membership in the LDS Church, making it a priority during his time as church president. Under Smith's leadership, Young participated in the building of the Kirtland and Nauvoo temples. Just four days after arriving in the Salt Lake Valley, Young designated the location for the Salt Lake Temple; he presided over its groundbreaking years later on April 6, 1853. During his tenure, Young oversaw construction of the Salt Lake Tabernacle and announced plans to build the St. George (1871), Manti (1875), and Logan (1877) temples. He also provisioned the building of the Endowment House, a "temporary temple" which began to be used in 1855 to provide temple ordinances to church members while the Salt Lake Temple was under construction. Teachings The majority of Young's teachings are contained in the 19 volumes of transcribed and edited sermons in the Journal of Discourses. The LDS Church's Doctrine and Covenants contains one section from Young that has been canonized as scripture, added in 1876. Polygamy Though polygamy was practiced by Young's predecessor Joseph Smith Jr., the practice is often associated with Young. Some Latter Day Saint denominations, such as the Community of Christ, consider Young the "Father of Mormon Polygamy". In 1853, Young made the church's first official statement on the subject since the church had arrived in Utah. Young acknowledged that the doctrine was challenging for many women, but stated its necessity for creating large families, proclaiming: "But the first wife will say, 'It is hard, for I have lived with my husband twenty years, or thirty, and have raised a family of children for him, and it is a great trial to me for him to have more women;' then I say it is time that you gave him up to other women who will bear children." Adam-God doctrine and blood atonement One of the more controversial teachings of Young during the Mormon Reformation was the Adam–God doctrine. According to Young, he was taught by Smith that Adam is "our Father and our God, and the only God with whom we have to do". According to the doctrine, Adam was once a mortal man who became resurrected and exalted. From another planet, Adam brought Eve, one of his wives, with him to the earth, where they became mortal by eating the fruit of the tree of knowledge of good and evil. After bearing mortal children and establishing the human race, Adam and Eve returned to their heavenly thrones where Adam acts as the god of this world. Later, as Young is generally understood to have taught, Adam returned to the earth to become the biological father of Jesus. The LDS Church has since repudiated the Adam–God doctrine. Young also taught the doctrine of blood atonement, in which the atonement of Jesus cannot redeem an eternal sin, which included apostasy, theft, fornication (but not sodomy), or adultery. Instead, those who committed such sins could partially atone for their sin by sacrificing their life in a way that sheds blood. The LDS Church has formally repudiated the doctrine as early as 1889, and multiple times since the days of Young. Priesthood ban for black men Young is generally considered to have instituted a church ban against conferring the priesthood on men of black African descent, who had been treated equally to white men in this respect under Smith's presidency. After settling in Utah in 1848, Young announced the ban, which also forbade blacks from participating in Mormon temple rites such as the endowment or sealings. On many occasions, Young taught that blacks were denied the priesthood because they were "the seed of Cain." In 1863, Young stated: "Shall I tell you the law of God in regard to the African race? If the white man who belongs to the chosen seed mixes his blood with the seed of Cain, the penalty, under the law of God, is death on the spot. This will always be so." Young was also a vocal opponent of theories of human polygenesis, being a firm voice for stating that all humans were the product of one creation. Throughout his time as prophet, Young went to great lengths to deny the assumption that he was the author of the practice of priesthood denial to black men, asserting instead that the Lord was. According to Young, the matter was beyond his personal control, and was divinely determined rather than historically or personally as many assumed. Young taught that the day would come when black men would again have the priesthood, saying that after "all the other children of Adam have the privilege of receiving the Priesthood, and of coming into the kingdom of God, and of being redeemed from the four-quarters of the earth, and have received their resurrection from the dead, then it will be time enough to remove the curse from Cain and his posterity." These racial restrictions remained in place until 1978, when the policy was rescinded by President Spencer W. Kimball, and the church subsequently "disavow[ed] theories advanced in the past" to explain this ban, thereby "plac[ing] the origins of black priesthood denial blame squarely on Brigham Young." Mormon Reformation During 1856 and 1857, a period of renewed emphasis on spirituality within the church known as the Mormon Reformation took place under Young's direction. The Mormon Reformation called for a spiritual reawakening among members of the church, and took place largely in the Utah Territory. Jedediah M. Grant, one of the key figures of the Reformation and one of Young's counselors, traveled throughout the Territory preaching to Latter-day Saint communities and settlements with the goal of inspiring them to reject sin and turn towards spiritual things. As part of the Reformation, almost all "active" or involved LDS Church members were rebaptized as a symbol of their commitment. At a church meeting on September 21, 1856, Brigham Young stated: “We need a reformation in the midst of this people; we need a thorough reform.” Large gatherings and meetings during this period were conducted by Young and Grant, and Young played a key role in the circulation of the Mormon Reformation with his emphasis on plural marriage, rebaptism, and passionate preaching and oration. It was during this period that the controversial doctrine of blood atonement was occasionally preached by Young, though it was repudiated in 1889 and never practiced by members of the church. The Reformation appeared to have ended completely by early 1858. Conflicts Shortly after the arrival of Young's pioneers, the new Latter-day Saint colonies were incorporated into the United States through the Mexican Cession. Young petitioned the U.S. Congress to create the State of Deseret. The Compromise of 1850 instead carved out Utah Territory and Young was appointed governor. As governor and church president, Young directed both religious and economic matters. He encouraged independence and self-sufficiency. Many cities and towns in Utah, and some in neighboring states, were founded under Young's direction. Young's leadership style has been viewed as autocratic. Utah War When federal officials received reports of widespread and systematic obstruction of federal officials in Utah (most notably judges), U.S. President James Buchanan decided in early 1857 to install a non-Mormon governor. Buchanan accepted the reports of the Runaway Officials without any further investigation, and the new non-sectarian governor was appointed and sent to the new territory accompanied by 2,500 soldiers. When Young received word in July that federal troops were headed to Utah with his replacement, he called out his militia to ambush the federal force using delaying tactics. During the defense of Utah, now called the Utah War, Young held the U.S. Army at bay for a winter by taking their cattle and burning supply wagons. Young eventually reached a settlement with the aid of a peace commission and agreed to step down as governor. He later received a pardon from Buchanan. Mountain Meadows massacre The degree of Young's involvement in the Mountain Meadows massacre, which took place in Washington County in 1857, is disputed. Leonard J. Arrington reports that Young received a rider at his office on the day of the massacre, and that when he learned of the contemplated attack by members of the church in Parowan and Cedar City, he sent back a letter directing that the Fancher party be allowed to pass through the territory unmolested. Young's letter reportedly arrived on September 13, 1857, two days after the massacre. As governor, Young had promised the federal government he would protect immigrants passing through Utah Territory, but over 120 men, women and children were killed in this incident. There is no debate concerning the involvement of individual Mormons from the surrounding communities by scholars. Only children under the age of seven, who were cared for by local Mormon families, survived, and the murdered members of the wagon train were left unburied. The remains of about 40 people were later found and buried, and Union Army officer James Henry Carleton had a large cross made from local trees, the transverse beam bearing the engraving, "Vengeance Is Mine, Saith The Lord: I Will Repay" and erected a cairn of rocks at the site. A large slab of granite was put up on which he had the following words engraved: "Here 120 men, women and children were massacred in cold blood early in September, 1857. They were from Arkansas." For two years, the monument stood as a memorial to those travelling the Spanish Trail through Mountain Meadow. According to Wilford Woodruff, in 1861 Young brought an entourage to Mountain Meadows and suggested that the monument read "Vengeance is mine and I have taken a little". Death Before his death in Salt Lake City on August 29, 1877, Young was suffering from cholera morbus and inflammation of the bowels. It is believed that he died of peritonitis from a ruptured appendix. His last words were "Joseph! Joseph! Joseph!", invoking the name of the late Joseph Smith Jr, founder of the Latter Day Saint movement. On September 2, 1877, Young's funeral was held in the Tabernacle with an estimated 12,000 to 15,000 people in attendance. He is buried on the grounds of the Mormon Pioneer Memorial Monument in the heart of Salt Lake City. A bronze marker was placed at the grave site June 10, 1938, by members of the Young Men and Young Women organizations, which he founded. Business ventures and wealth Young engaged in a vast assortment of commercial ventures by himself and in partnership with others. These included a wagon express company, a ferryboat company, a railroad and the manufacturing of processed lumber, wool, sugar beets, iron, and liquor. Young achieved greatest success in real estate. He also tried to promote Mormon self-sufficiency by establishing collectivist communities, known as the United Order of Enoch. Young was also involved in the organization of the Salt Lake Gas Works, the Salt Lake Water Works, an insurance company, a bank, and the ZCMI store in downtown Salt Lake City. In 1873, he announced that he would step down as president of the Deseret National Bank and of ZCMI, as well as from his role as trustee-in-trust for the church. He cited as his reason for this that he was ready to relieve himself from the burden of "secular affairs." At the time of his death, Young was the wealthiest man in Utah, with an estimated personal fortune of $600,000 (). Legacy Impact Young had many nicknames during his lifetime, among the most popular being "American Moses" (alternatively, "Modern Moses" or "Mormon Moses"), because, like the biblical figure, Young led his followers, the Mormon pioneers, in an exodus through a desert, to what they saw as a promised land. Young was dubbed by his followers the "Lion of the Lord" for his bold personality and commonly was called "Brother Brigham" by Latter-day Saints. A century after Young's death, historian Rodman W. Paul wrote, He credited Young's leadership with helping to settle much of the American West: Memorials to Young include a bronze statue in front of the Abraham O. Smoot Administration Building, Brigham Young University; a marble statue in the National Statuary Hall Collection at the United States Capitol, donated by the State of Utah in 1950; and a statue atop the This is the Place Monument in Salt Lake City. Views of race and slavery Young had a somewhat mixed view of slavery which historian John G. Turner called a "bundle of contradictions". In the 1840s, Young strove to keep aloof from nationwide political debates over slavery, avoiding committing to either antislavery or proslavery positions. In the early 1850s, he expressed some support for the antislavery "free soil" position in American politics, and in January 1852, he declared in a speech that "no property can or should be recognized as existing in slaves", suggesting opposition to the existence of slavery. However, two weeks later Young declared himself a "firm believer in slavery". There is also evidence to suggest Young believed in the racial superiority of white men. His manuscript history from January 5, 1852, which was published in the Deseret News, reads:The negro . . . should serve the seed of Abraham; he should not be a ruler, nor vote for men to rule over me nor my brethren. The Constitution of Deseret is silent upon this, we meant it should be so. The seed of Canaan cannot hold any office, civil or ecclesiastical. . . . The decree of God that Canaan should be a servant of servants unto his brethren (i.e., Shem and Japhet [sic]) is in full force. The day will come when the seed of Canaan will be redeemed and have all the blessings their brethren enjoy. Any person that mingles his seed with the seed of Canaan forfeits the right to rule and all the blessings of the Priesthood of God; and unless his blood were spilled and that of his offspring he nor they could not be saved until the posterity of Canaan are redeemed.On this topic, Young wrote: "They have not wisdom to act like white men." Young adopted the Christian idea of the Curse of Ham—a racist interpretation of Genesis 9 which white proponents of slavery in antebellum America used to justify enslaving black people of African descent—and applied it liberally and literally. Young also predicted a future in which Chinese and Japanese people would immigrate to America. He averred that Chinese and Japanese immigrants would need to be governed by white men as they would have no understanding of government. Family and descendants Young was a polygamist, having at least fifty-six wives. The policy and practice of polygamy was difficult for many in the church to accept. Young stated that upon being taught about plural marriage by Joseph Smith: "It was the first time in my life that I desired the grave." By the time of his death, Young had fifty-seven children by sixteen of his wives; forty-six of his children reached adulthood. Sources have varied on the number of Young's wives, as well as their ages. This is due to differences in what scholars have considered to be a "wife". There were fifty-six women who Young was sealed to during his lifetime. While the majority of the sealings were "for eternity", some were "for time only," meaning that Young was sealed to these women as a proxy for their previous husbands who had passed away. Researchers note that not all of the fifty-six marriages were conjugal. Young did not live with a number of his wives or publicly hold them out as wives, which has led to confusion on the number and their identities. Thirty-one of his wives were not connubial and had exchanged eternity-only vows with him, and he had children by only sixteen of his wives. Of Young's fifty-six wives, twenty-one had never been married before; seventeen were widows; six were divorced; six had living husbands and the marital status of six others is unknown. Young built the Lion House, the Beehive House, the Gardo House, and the White House in downtown Salt Lake City to accommodate his sizable family. The Beehive House and the Lion House remain as prominent Salt Lake City landmarks. At the north end of the Beehive House was a family store, at which Young's wives and children had running accounts and could buy what they needed. For a time, Karl Maeser acted as a private tutor to the Young household—which included many who were not members of Young's immediate family. At the time of Young's death, nineteen of his wives had predeceased him; he was divorced from ten, and twenty-three survived him. The status of four was unknown. A few of his wives served in administrative positions in the church, such as Zina Huntington and Eliza R. Snow. In his will, Young shared his estate with the sixteen surviving wives who had lived with him; the six surviving non-conjugal wives were not mentioned in the will. Notable descendants In 1902, 25 years after his death, The New York Times established that Young's direct descendants numbered more than 1,000. Some of Young's descendants have become leaders in the LDS Church, as well as prominent political and cultural figures. Cultural references In comics Brigham Young appears at the end of the bande dessinée Le Fil qui chante, the last in the Lucky Luke series by René Goscinny. In literature The Scottish poet John Lyon, who was an intimate friend of Young, wrote Brigham the Bold in tribute to him after his death. Florence Claxton's graphic novel, The Adventures of a Woman in Search of Her Rights (1872), satirizes a would-be emancipated woman whose failure to establish an independent career results in her marriage to Young before she wakes to discover she's been dreaming. Arthur Conan Doyle based his first Sherlock Holmes novel, A Study in Scarlet, on Mormon history, mentioning Young by name. When asked to comment on the story, which had, "provoked the animosity of the Mormon faithful", Doyle noted, "all I said about the Danite Band and the murders is historical so I cannot withdraw that though it is likely that in a work of fiction it is stated more luridly than in a work of history." Doyle's daughter stated: "You know father would be the first to admit that his first Sherlock Holmes novel was full of errors about the Mormons." Mark Twain devoted a chapter and much of two appendices to Young in Roughing It. In the appendix, Twain describes Young as a theocratic "absolute monarch" defying the will of the U.S. government, and alleges using a dubious source that Young had ordered the Mountain Meadows massacre. Oliver Wendell Holmes Sr., talking about his fondness of trees, joked in his The Autocrat of the Breakfast-Table: "I call all trees mine that I have put my wedding-ring on, and I have as many tree-wives as Brigham Young has human ones." In movies Young was played by Dean Jagger in the 1940 film Brigham Young. In the 1995 film The Avenging Angel, the role of Young was played by Charlton Heston. Brigham Young was also played by Terence Stamp in the 2007 film September Dawn. In television Byron Morrow played Young in a cameo appearance in the Death Valley Days 1966 episode "An Organ for Brother Brigham". In the story line, the organ built and guided west to Salt Lake City by Joseph Harris Ridges (1827–1914) of Australia becomes mired in the sand. Wagonmaster Luke Winner (Morgan Woodward) feels compelled to leave the instrument behind until Ridges finds solid rock under the sand. In another Death Valley Days episode in 1969, "Biscuits and Billy, the Kid", Michael Hinn (1913–1988) of the former Boots and Saddles western series was cast as Young. In the story line, the Tugwell family, Jason (Ben Cooper), Ellie (Emily Banks), and Mary (Erin Moran), are abandoned by their guide while on a wagon train from Utah to California. Gregg Henry depicts Young in the fourth (2014) and fifth (2015) seasons of the TV series Hell on Wheels, a fictional story about the construction of the First Transcontinental Railroad. As the competing rail lines approach Utah from the east and west coasts, Young supplies Mormon laborers to both railroad companies and negotiates with the railways to have them make Salt Lake City their meeting point. In the Season 5 mid-season finale, "False Prophets", Young's son, Phineas, attempts to murder his father. Persuaded by The Swede, Phineas believed he was the chosen one to go forward to lead the Mormons, instead of his father. In theater In the 2011 musical The Book of Mormon, Young is portrayed as a tyrannical American regional warlord, cursed by God to have a clitoris for a nose—a parable cautioning against female genital mutilation. He encounters Joseph Smith and attempts to ambush his party of Mormons, but, rather than engaging with "the Clitoris Man", Smith shows mercy, rubbing one of the frogs that God has given him to have sex with to cure his AIDS on Young's face, curing his AIDS, and so moving him that he decides to convert to the faith. Later, after taking up the mantle of Mormon leader following Smith's death from dysentery, Young is among those visited by Jesus and told to have as much sex as they possibly can, to ensure the propagation of the Mormon faith. Literary works Since Young's death, a number of works have published collections of his discourses and sayings.

A casino is a facility for certain types of gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shopping, cruise ships, and other tourist attractions. Some casinos are also known for hosting live entertainment, such as stand-up comedy, concerts, and sports. and usage Casino is of Italian origin; the root means a house. The term casino may mean a small country villa, summerhouse, or social club. During the 19th century, casino came to include other public buildings where pleasurable activities took place; such edifices were usually built on the grounds of a larger Italian villa or palazzo, and were used to host civic town functions, including dancing, gambling, music listening, and sports. Examples in Italy include Villa Farnese and Villa Giulia, and in the US the Newport Casino in Newport, Rhode Island. In modern-day Italian, a is a brothel (also called , literally "closed house"), a mess (confusing situation), or a noisy environment; a gaming house is spelt , with an accent. Not all casinos are used for gaming. The Catalina Casino, on Santa Catalina Island, California, has never been used for traditional games of chance, which were already outlawed in California by the time it was built. The Copenhagen Casino was a Danish theatre which also held public meetings during the 1848 Revolution, which made Denmark a constitutional monarchy. In military and non-military usage, a (Spanish) or (German) is an officers' mess. History of gambling houses The precise origin of gambling is unknown. It is generally believed that gambling in some form or another has been seen in almost every society in history. From Ancient Mesopotamia, Greeks and Romans to Napoleon's France and Elizabethan England, much of history is filled with stories of entertainment based on games of chance. The first known European gambling house, not called a casino although meeting the modern definition, was the Ridotto, established in Venice, Italy, in 1638 by the Great Council of Venice to provide controlled gambling during the carnival season. It was closed in 1774 as the city government felt it was impoverishing the local gentry. In American history, early gambling establishments were known as saloons. The creation and importance of saloons was greatly influenced by four major cities: New Orleans, St. Louis, Chicago and San Francisco. It was in the saloons that travelers could find people to talk to, drink with, and often gamble with. During the early 20th century in the US, gambling was outlawed by state legislation. However, in 1931, gambling was legalized throughout the state of Nevada, where the US's first legalized casinos were set up. In 1976 New Jersey allowed gambling in Atlantic City, now the US's second largest gambling city. Gambling in casinos Most jurisdictions worldwide have a minimum gambling age of 18 to 21. Customers gamble by playing games of chance, in some cases with an element of skill, such as craps, roulette, baccarat, blackjack, and video poker. Most games have mathematically determined odds that ensure the house has at all times an advantage over the players. This can be expressed more precisely by the notion of expected value, which is uniformly negative (from the player's perspective). This advantage is called the house edge. In games such as poker where players play against each other, the house takes a commission called the rake. Casinos sometimes give out complimentary items or comps to gamblers. Payout is the percentage of funds ("winnings") returned to players. Casinos in the United States say that a player staking money won from the casino is playing with the house's money. Video Lottery Machines (slot machines) have become one of the most popular forms of gambling in casinos. investigative reports have started calling into question whether the modern-day slot-machine is addictive. Design Casino design—regarded as a psychological exercise—is an intricate process that involves optimising floor plan, décor and atmospherics to encourage gambling. Factors influencing gambling tendencies include sound, odour and lighting. Natasha Dow Schüll, an anthropologist at the Massachusetts Institute of Technology, highlights the decision of the audio directors at Silicon Gaming to make its slot machines resonate in "the universally pleasant tone of C, sampling existing casino soundscapes to create a sound that would please but not clash". Alan Hirsch, founder of the Smell & Taste Treatment and Research Foundation in Chicago, studied the impact of certain scents on gamblers, discerning that a pleasant albeit unidentifiable odor released by Las Vegas slot machines generated about 50% more in daily revenue. He suggested that the scent acted as an aphrodisiac, causing a more aggressive form of gambling. Markets The following lists major casino markets in the world with casino revenue of over US$1 billion as published in PricewaterhouseCoopers's report on the outlook for the global casino market: By region By markets By company According to Bloomberg, accumulated revenue of the biggest casino operator companies worldwide amounted to almost US$55 billion in 2011. SJM Holdings Ltd. was the leading company in this field, earning $9.7 bn in 2011, followed by Las Vegas Sands Corp. at $7.4 bn. The third-biggest casino operator company (based on revenue) was Caesars Entertainment, with revenue of US$6.2 bn. Significant sites While there are casinos in many places, a few places have become well known specifically for gambling. Perhaps the place almost defined by its casino is Monte Carlo, but other places are known as gambling centers. Monte Carlo, Monaco Monte Carlo Casino, located in Monte Carlo city, in Monaco, is a casino and a tourist attraction. Monte Carlo Casino has been depicted in many books, including Ben Mezrich's Busting Vegas, where a group of Massachusetts Institute of Technology students beat the casino out of nearly $1 million. This book is based on real people and events; however, many of those events are contested by main character Semyon Dukach. Monte Carlo Casino has also been featured in multiple James Bond novels and films. The casino is mentioned in the song "The Man Who Broke the Bank at Monte Carlo" as well as the film of the same name. Campione d'Italia Casinò di Campione is located in the tiny Italian enclave of Campione d'Italia, within Ticino, Switzerland. The casino was founded in 1917 as a site to gather information from foreign diplomats during the First World War. Today it is owned by the Italian government, and operated by the municipality. With gambling laws being less strict than in Italy and Switzerland, it is among the most popular gambling destination besides Monte Carlo. The income from the casino is sufficient for the operation of Campione without the imposition of taxes, or obtaining of other revenue. In 2007, the casino moved into new premises of more than , making it the largest casino in Europe. The new casino was built alongside the old one, which dated from 1933 and has since been demolished. Malta the archipelago of Malta is a particularly famous place for casinos in particular the historic casino at the princely residence of Dragonara Macau The former Portuguese colony of Macau, a special administrative region of the People's Republic of China since 1999, is a popular destination for visitors who wish to gamble. This started in Portuguese times, when Macau was popular with visitors from nearby Hong Kong, where gambling was more closely regulated. The Venetian Macao is currently the largest casino in the world. Macau also surpassed Las Vegas as the largest gambling market in the world. Germany Machine-based gaming is only permitted in land-based casinos, restaurants, bars and gaming halls, and only subject to a licence. Online slots are, at the moment, only permitted if they are operated under a Schleswig-Holstein licence. AWPs are governed by federal law – the Trade Regulation Act and the Gaming Ordinance. Portugal The Casino Estoril, located in the municipality of Cascais, on the Portuguese Riviera, near Lisbon, is the largest casino in Europe by capacity. During the Second World War, it was reputed to be a gathering point for spies, dispossessed royals, and wartime adventurers; it became an inspiration for Ian Fleming's James Bond 007 novel Casino Royale. Singapore Singapore is an up-and-coming destination for visitors wanting to gamble, although there are currently only two casinos (both foreign owned), in Singapore. The Marina Bay Sands is the most expensive standalone casino in the world, at a price of US$8 billion, and is among the world's ten most expensive buildings. The Resorts World Sentosa has the world's largest oceanarium. Russia There are 4 legal gaming zones in Russia: "Siberian Coin" (Altay), "Yantarnaya" (Kaliningrad region), "Azov-city" (Rostov region) and "Primorie" (Primorie region). United States With currently over 1,000 casinos, the United States has the largest number of casinos in the world. The number continues to grow steadily as more states seek to legalize casinos. 40 states now have some form of casino gambling. Interstate competition, such as gaining tourism, has been a driving factor to continuous legalization. Relatively small places such as Las Vegas are best known for gambling; larger cities such as Chicago are not defined by their casinos in spite of the large turnover. The Las Vegas Valley has the largest concentration of casinos in the United States. Based on revenue, Atlantic City, New Jersey ranks second, and the Chicago region third. Top American casino markets by revenue (2015 annual revenues): Las Vegas Strip $6.348 billion Atlantic City $2.426 billion Chicago region $2.002 billion New York City $1.400 billion Detroit $1.376 billion Baltimore–Washington Metropolitan Area $1.306 billion Philadelphia $1.192 billion Mississippi Gulf Coast $1.135 billion St. Louis $1.007 billion The Poconos $965.56 million Lake Charles, Louisiana $907.51 million Boulder Strip $784.35 million Kansas City $782.05 million Shreveport $732.51 million The Nevada Gaming Control Board divides Clark County, which is coextensive with the Las Vegas metropolitan area, into seven market regions for reporting purposes. Native American gaming has been responsible for a rise in the number of casinos outside of Las Vegas and Atlantic City. Security Given the large amounts of currency handled within a casino, both patrons and staff may be tempted to cheat and steal, in collusion or independently; most casinos have security measures to prevent this. Security cameras located throughout the casino are the most basic measure. Modern casino security is usually divided between a physical security force and a specialized surveillance department. The physical security force usually patrols the casino and responds to calls for assistance and reports of suspicious or definite criminal activity. A specialized surveillance department operates the casino's closed circuit television system, known in the industry as the eye in the sky. Both of these specialized casino security departments work very closely with each other to ensure the safety of both guests and the casino's assets, and have been quite successful in preventing crime. Some casinos also have catwalks in the ceiling above the casino floor, which allow surveillance personnel to look directly down, through one way glass, on the activities at the tables and slot machines. When it opened in 1989, The Mirage was the first casino to use cameras full-time on all table games. In addition to cameras and other technological measures, casinos also enforce security through rules of conduct and behavior; for example, players at card games are required to keep the cards they are holding in their hands visible at all times. Business practices Over the past few decades, casinos have developed many different marketing techniques for attracting and maintaining loyal patrons. Many casinos use a loyalty rewards program used to track players' spending habits and target their patrons more effectively, by sending mailings with free slot play and other promotions. Casino Helsinki in Helsinki, Finland, for example, donates all of its profits to charity. Crime Casinos have been linked to organised crime, with early casinos in Las Vegas originally dominated by the American Mafia and in Macau by Triad syndicates. According to some police reports, local incidence of reported crime often doubles or triples within three years of a casino's opening. In a 2004 report by the US Department of Justice, researchers interviewed people who had been arrested in Las Vegas and Des Moines and found that the percentage of problem or pathological gamblers among the arrestees was three to five times higher than in the general population. It has been said that economic studies showing a positive relationship between casinos and crime usually fail to consider the visiting population: they count crimes committed by visitors but do not count visitors in the population measure, which overstates the crime rate. Part of the reason this methodology is used, despite the overstatement, is that reliable data on tourist count are often not available. Occupational health and safety There are unique occupational health issues in the casino industry. The most common are from cancers resulting from exposure to second-hand tobacco smoke and musculoskeletal injury (MSI) from repetitive motion injuries while running table games over many hours.

Catalan (; autonym: or ; ), known in the Valencian Community and Carche as Valencian, is a Western Romance language derived from Vulgar Latin. It is the official language of Andorra, and a co-official language of three autonomous communities in eastern Spain: Catalonia, the Valencian Community, and the Balearic Islands. It also has semi-official status in the Italian comune of Alghero. It is also spoken in the Pyrénées-Orientales department of France and in two further areas in eastern Spain: the eastern strip of Aragon and the Carche area in the Region of Murcia. The Catalan-speaking territories are often called the or "Catalan Countries". The language evolved from Vulgar Latin in the Middle Ages around the eastern Pyrenees. Nineteenth-century Spain saw a Catalan literary revival, culminating in the early 1900s. Etymology and pronunciation The word Catalan is derived from the territorial name of Catalonia, itself of disputed etymology. The main theory suggests that (Latin Gathia Launia) derives from the name Gothia or Gauthia ("Land of the Goths"), since the origins of the Catalan counts, lords and people were found in the March of Gothia, whence Gothland > Gothlandia > Gothalania > Catalonia theoretically derived. In English, the term referring to a person first appears in the mid 14th century as Catelaner, followed in the 15th century as Catellain (from French). It is attested a language name since at least 1652. The word Catalan can be pronounced in English as , or . The endonym is pronounced in the Eastern Catalan dialects, and in the Western dialects. In the Valencian Community and Carche, the term is frequently used instead. Thus, the name "Valencian", although often employed for referring to the varieties specific to the Valencian Community and Carche, is also used by Valencians as a name for the language as a whole, synonymous with "Catalan". Both uses of the term have their respective entries in the dictionaries by the AVL and the IEC. See also status of Valencian below. History Middle Ages By the 9th century, Catalan had evolved from Vulgar Latin on both sides of the eastern end of the Pyrenees, as well as the territories of the Roman province of Hispania Tarraconensis to the south. From the 8th century onwards the Catalan counts extended their territory southwards and westwards at the expense of the Muslims, bringing their language with them. This process was given definitive impetus with the separation of the County of Barcelona from the Carolingian Empire in 988. In the 11th century, documents written in macaronic Latin begin to show Catalan elements, with texts written almost completely in Romance appearing by 1080. Old Catalan shared many features with Gallo-Romance, diverging from Old Occitan between the 11th and 14th centuries. During the 11th and 12th centuries the Catalan rulers expanded southward to the Ebro river, and in the 13th century they conquered the Land of Valencia and the Balearic Islands. The city of Alghero in Sardinia was repopulated with Catalan speakers in the 14th century. The language also reached Murcia, which became Spanish-speaking in the 15th century. In the Low Middle Ages, Catalan went through a golden age, reaching a peak of maturity and cultural richness. Examples include the work of Majorcan polymath Ramon Llull (1232–1315), the Four Great Chronicles (13th–14th centuries), and the Valencian school of poetry culminating in Ausiàs March (1397–1459). By the 15th century, the city of Valencia had become the sociocultural center of the Crown of Aragon, and Catalan was present all over the Mediterranean world. During this period, the Royal Chancery propagated a highly standardized language. Catalan was widely used as an official language in Sicily until the 15th century, and in Sardinia until the 17th. During this period, the language was what Costa Carreras terms "one of the 'great languages' of medieval Europe". Martorell's outstanding novel of chivalry Tirant lo Blanc (1490) shows a transition from Medieval to Renaissance values, something that can also be seen in Metge's work. The first book produced with movable type in the Iberian Peninsula was printed in Catalan. Start of the modern era With the union of the crowns of Castille and Aragon in 1479, the use of Spanish gradually became more prestigious and marked the start of the decline of Catalan. Starting in the 16th century, Catalan literature came under the influence of Spanish, and the urban and literary classes became bilingual. With the Treaty of the Pyrenees (1659), Spain ceded the northern part of Catalonia to France, and soon thereafter the local Catalan varieties came under the influence of French, which in 1700 became the sole official language of the region. Shortly after the French Revolution (1789), the French First Republic prohibited official use of, and enacted discriminating policies against, the regional languages of France, such as Catalan, Alsatian, Breton, Occitan, Flemish, and Basque. France: 19th to 20th centuries Following the French establishment of the colony of Algeria from 1830 onward, it received several waves of Catalan-speaking settlers. People from the Spanish Alacant province settled around Oran, whereas Algiers received immigration from Northern Catalonia and Menorca. Their speech was known as patuet. By 1911, the number of Catalan speakers was around 100,000. After the declaration of independence of Algeria in 1962, almost all the Catalan speakers fled to Northern Catalonia (as Pieds-Noirs) or Alacant. The government of France formally recognizes only French as an official language. Nevertheless, on 10 December 2007, the General Council of the Pyrénées-Orientales officially recognized Catalan as one of the languages of the department and seeks to further promote it in public life and education. Spain: 18th to 20th centuries In Spain, the decline of Catalan continued into the 18th century. The defeat of the pro-Habsburg coalition in the War of Spanish Succession (1714) initiated a series of laws which, among other centralizing measures, imposed the use of Spanish in legal documentation all over Spain. However, the 19th century saw a Catalan literary revival (), which has continued up to the present day. This period starts with Aribau's Ode to the Homeland (1833); followed in the second half of the 19th century, and the early 20th by the work of Verdaguer (poetry), Oller (realist novel), and Guimerà (drama). In the 19th century, the region of Carche, in the province of Murcia was repopulated with Catalan speakers from the Land of Valencia. Catalan obtained an orthographic standardization in 1913 and became an official language during the Second Spanish Republic (1931–1939). The Second Spanish Republic saw a brief period of tolerance, with most restrictions against Catalan lifted. The Catalan language and culture were suppressed during the Spanish Civil War (1936–1939) and the subsequent decades in Francoist Catalonia. The Francoist dictatorship (1939–1975) banned the use of Catalan in schools and in public administration. Oppression of the Catalan language and identity was carried out in schools, through governmental bodies, and in religious centers. Franco's desire for a homogenous Spanish population resonated with some Catalans in favor of his regime, primarily members of the upper class, who began to reject the use of Catalan. Despite all of these hardships, Catalan continued to be used privately within households, and it was able to survive Francisco Franco's dictatorship. Several prominent Catalan authors resisted the suppression through literature. In addition to the loss of prestige for Catalan and the prohibition of its use in schools, migration during the 1950s into Catalonia from other parts of Spain also contributed to the diminished use of the language. These migrants were often unaware of the existence of Catalan, and thus felt no need to learn or use it. Catalonia was the economic powerhouse of Spain, so these migrations continued to occur from all corners of the country. Historically, employment opportunities were reduced for those who are not bilingual. Present day Since the Spanish transition to democracy (1975–1982), Catalan has been institutionalized as an official language, language of education, and language of mass media; all of which have contributed to its increased prestige. In Catalonia, there is an unparalleled large bilingual European non-state linguistic community. The teaching of Catalan is mandatory in all schools, but it is possible to use Spanish for studying in the public education system of Catalonia in two situations – if the teacher assigned to a class chooses to use Spanish, or during the learning process of one or more recently arrived immigrant students. There is also some intergenerational shift towards Catalan. According to the Statistical Institute of Catalonia, in 2013 the Catalan language is the second most commonly used in Catalonia, after Spanish, as a native or self-defining language: 7% of the population self-identifies with both Catalan and Spanish equally, 36.4% with Catalan and 47.5% only Spanish. In 2003 the same studies concluded no language preference for self-identification within the population above 15 years old: 5% self-identified with both languages, 44.3% with Catalan and 47.5% with Spanish. To promote use of Catalan, the Generalitat de Catalunya (Catalonia's official Autonomous government) spends part of its annual budget on the promotion of the use of Catalan in Catalonia and in other territories, with entities such as (Consortium for Linguistic Normalization) In Andorra, Catalan has always been the sole official language. Since the promulgation of the 1993 constitution, several policies favoring Catalan have been enforced, like Catalan medium education. On the other hand, there are several language shift processes currently taking place. In the Northern Catalonia area of France, Catalan has followed the same trend as the other minority languages of France, with most of its native speakers being 60 or older (as of 2004). Catalan is studied as a foreign language by 30% of the primary education students, and by 15% of the secondary. The cultural association promotes a network of community-run schools engaged in Catalan language immersion programs. In Alicante province, Catalan is being replaced by Spanish and in Alghero by Italian. There is also well ingrained diglossia in the Valencian Community, Ibiza, and to a lesser extent, in the rest of the Balearic islands. Classification and relationship with other Romance languages One classification of Catalan is given by Pèire Bèc: Romance languages Italo-Western languages Western Romance languages Gallo-Iberian languages Gallo-Romance languages Occitano-Romance languages Catalan language However, the ascription of Catalan to the Occitano-Romance branch of Gallo-Romance languages is not shared by all linguists and philologists, particularly among Spanish ones, such as Ramón Menéndez Pidal. Catalan bears varying degrees of similarity to the linguistic varieties subsumed under the cover term Occitan language (see also differences between Occitan and Catalan and Gallo-Romance languages). Thus, as it should be expected from closely related languages, Catalan today shares many traits with other Romance languages. Relationship with other Romance languages Some include Catalan in Occitan, as the linguistic distance between this language and some Occitan dialects (such as the Gascon language) is similar to the distance among different Occitan dialects. Catalan was considered a dialect of Occitan until the end of the 19th century and still today remains its closest relative. Catalan shares many traits with the other neighboring Romance languages (Occitan, French, Italian, Sardinian as well as Spanish and Portuguese among others). However, despite being spoken mostly on the Iberian Peninsula, Catalan has marked differences with the Iberian Romance group (Spanish and Portuguese) in terms of pronunciation, grammar, and especially vocabulary; showing instead its closest affinity with languages native to France and northern Italy, particularly Occitan and to a lesser extent Gallo-Romance (Franco-Provençal, French, Gallo-Italian). According to Ethnologue, the lexical similarity between Catalan and other Romance languages is: 87% with Italian; 85% with Portuguese and Spanish; 76% with Ladin; 75% with Sardinian; and 73% with Romanian. During much of its history, and especially during the Francoist dictatorship (1939–1975), the Catalan language was ridiculed as a mere dialect of Spanish. This view, based on political and ideological considerations, has no linguistic validity. Spanish and Catalan have important differences in their sound systems, lexicon, and grammatical features, placing the language in features closer to Occitan (and French). There is evidence that, at least from the 2nd century , the vocabulary and phonology of Roman Tarraconensis was different from the rest of Roman Hispania. Differentiation arose generally because Spanish, Asturian, and Galician-Portuguese share certain peripheral archaisms (Spanish , Asturian and Portuguese vs. Catalan , Occitan "to boil") and innovatory regionalisms (Sp , Ast vs. Cat , Oc "bullock"), while Catalan has a shared history with the Western Romance innovative core, especially Occitan. Like all Romance languages, Catalan has a handful of native words which are unique to it, or rare elsewhere. These include: verbs: 'to fasten; transfix' > 'to compose, write up', > 'to combine, conjugate', > 'to wake; awaken', 'to thicken; crowd together' > 'to save, keep', > 'to miss, yearn, pine for', 'to investigate, track' > Old Catalan enagar 'to incite, induce', > OCat ujar 'to exhaust, fatigue', > 'to appease, mollify', > 'to reject, refuse'; nouns: > 'pomace', > 'reedmace', > 'catarrh', > 'snowdrift', > 'ardor, passion', > 'brake', > 'avalanche', > 'edge, border', 'sawfish' > pestriu > 'thresher shark, smooth hound; ray', 'live coal' > 'spark', > tardaó > 'autumn'. The Gothic superstrate produced different outcomes in Spanish and Catalan. For example, Catalan "mud" and "to roast", of Germanic origin, contrast with Spanish and , of Latin origin; whereas Catalan "spinning wheel" and "temple", of Latin origin, contrast with Spanish and , of Germanic origin. The same happens with Arabic loanwords. Thus, Catalan "large earthenware jar" and "tile", of Arabic origin, contrast with Spanish and , of Latin origin; whereas Catalan "oil" and "olive", of Latin origin, contrast with Spanish and . However, the Arabic element in Spanish is generally much more prevalent. Situated between two large linguistic blocks (Iberian Romance and Gallo-Romance), Catalan has many unique lexical choices, such as "to miss somebody", "to calm somebody down", and "reject". Geographic distribution Catalan-speaking territories Traditionally Catalan-speaking territories are sometimes called the (Catalan Countries), a denomination based on cultural affinity and common heritage, that has also had a subsequent political interpretation but no official status. Various interpretations of the term may include some or all of these regions. Number of speakers The number of people known to be fluent in Catalan varies depending on the sources used. A 2004 study did not count the total number of speakers, but estimated a total of 9–9.5 million by matching the percentage of speakers to the population of each area where Catalan is spoken. The web site of the Generalitat de Catalunya estimated that as of 2004 there were 9,118,882 speakers of Catalan. These figures only reflect potential speakers; today it is the native language of only 35.6% of the Catalan population. According to Ethnologue, Catalan had 4.1 million native speakers and 5.1 million second-language speakers in 2021. According to a 2011 study the total number of Catalan speakers is over 9.8 million, with 5.9 million residing in Catalonia. More than half of them speak Catalan as a second language, with native speakers being about 4.4 million of those (more than 2.8 in Catalonia). Very few Catalan monoglots exist; basically, virtually all of the Catalan speakers in Spain are bilingual speakers of Catalan and Spanish, with a sizable population of Spanish-only speakers of immigrant origin (typically born outside Catalonia or with both parents born outside Catalonia) existing in the major Catalan urban areas as well. In Roussillon, only a minority of French Catalans speak Catalan nowadays, with French being the majority language for the inhabitants after a continued process of language shift. According to a 2019 survey by the Catalan government, 31.5% of the inhabitants of Catalonia have Catalan as first language at home whereas 52.7% have Spanish, 2.8% both Catalan and Spanish and 10.8% other languages. Spanish is the most spoken language in Barcelona (according to the linguistic census held by the Government of Catalonia in 2013) and it is understood almost universally. According to this census of 2013 Catalan is also very commonly spoken in the city of 1,501,262: it is understood by 95% of the population, while 72.3% over the age of 2 can speak it (1,137,816), 79% can read it (1,246.555), and 53% can write it (835,080). The proportion in Barcelona who can speak it, 72.3%, is lower than that of the overall Catalan population, of whom 81.2% over the age of 15 speak the language. Knowledge of Catalan has increased significantly in recent decades thanks to a language immersion educational system. An important social characteristic of the Catalan language is that all the areas where it is spoken are bilingual in practice: together with the French language in Roussillon, with Italian in Alghero, with Spanish and French in Andorra and with Spanish in the rest of the territories. 1. The number of people who understand Catalan includes those who can speak it. 2. Figures relate to all self-declared capable speakers, not just native speakers. Level of knowledge (% of the population 15 years old and older). Social use (% of the population 15 years old and older). Native language Phonology Catalan phonology varies by dialect. Notable features include: Marked contrast of the vowel pairs and , as in other Western Romance languages, other than Spanish. Lack of diphthongization of Latin short , , as in Galician and Portuguese, but unlike French, Spanish, or Italian. Abundance of diphthongs containing , as in Galician and Portuguese. In contrast to other Romance languages, Catalan has many monosyllabic words, and these may end in a wide variety of consonants, including some consonant clusters. Additionally, Catalan has final obstruent devoicing, which gives rise to an abundance of such couplets as "(male friend") vs. ("female friend"). Central Catalan pronunciation is considered to be standard for the language. The descriptions below are mostly representative of this variety. For the differences in pronunciation between the different dialects, see the section on pronunciation of dialects in this article. Vowels Catalan has inherited the typical vowel system of Vulgar Latin, with seven stressed phonemes: , a common feature in Western Romance, with the exception of Spanish. Balearic also has instances of stressed . Dialects differ in the different degrees of vowel reduction, and the incidence of the pair . In Central Catalan, unstressed vowels reduce to three: ; ; remains distinct. The other dialects have different vowel reduction processes (see the section pronunciation of dialects in this article). Consonants The consonant system of Catalan is rather conservative. has a velarized allophone in syllable coda position in most dialects. However, is velarized irrespective of position in Eastern dialects like Majorcan and standard Eastern Catalan. occurs in Balearic, Algherese, standard Valencian and some areas in southern Catalonia. It has merged with elsewhere. Voiced obstruents undergo final-obstruent devoicing: . Voiced stops become lenited to approximants in syllable onsets, after continuants: > , > , > . Exceptions include after lateral consonants, and after . In coda position, these sounds are realized as stops, except in some Valencian dialects where they are lenited. There is some confusion in the literature about the precise phonetic characteristics of , , , . Some sources describe them as "postalveolar". Others as "back alveolo-palatal", implying that the characters would be more accurate. However, in all literature only the characters for palato-alveolar affricates and fricatives are used, even when the same sources use for other languages like Polish and Chinese. The distribution of the two rhotics and closely parallels that of Spanish. Between vowels, the two contrast, but they are otherwise in complementary distribution: in the onset of the first syllable in a word, appears unless preceded by a consonant. Dialects vary in regards to rhotics in the coda with Western Catalan generally featuring and Central Catalan dialects featuring a weakly trilled unless it precedes a vowel-initial word in the same prosodic unit, in which case appears. In careful speech, , , may be geminated. Geminated may also occur. Some analyze intervocalic as the result of gemination of a single rhotic phoneme. This is similar to the common analysis of Spanish and Portuguese rhotics. Phonological evolution Sociolinguistics Catalan sociolinguistics studies the situation of Catalan in the world and the different varieties that this language presents. It is a subdiscipline of Catalan philology and other affine studies and has as an objective to analyze the relation between the Catalan language, the speakers and the close reality (including the one of other languages in contact). Preferential subjects of study Dialects of Catalan Variations of Catalan by class, gender, profession, age and level of studies Process of linguistic normalization Relations between Catalan and Spanish or French Perception on the language of Catalan speakers and non-speakers Presence of Catalan in several fields: tagging, public function, media, professional sectors Dialects Overview The dialects of the Catalan language feature a relative uniformity, especially when compared to other Romance languages; both in terms of vocabulary, semantics, syntax, morphology, and phonology. Mutual intelligibility between dialects is very high, estimates ranging from 90% to 95%. The only exception is the isolated idiosyncratic Algherese dialect. Catalan is split in two major dialectal blocks: Eastern Catalan, and Western Catalan. The main difference lies in the treatment of unstressed and ; which have merged to in Eastern dialects, but which remain distinct as and in Western dialects. There are a few other differences in pronunciation, verbal morphology, and vocabulary. Western Catalan comprises the two dialects of Northwestern Catalan and Valencian; the Eastern block comprises four dialects: Central Catalan, Balearic, Rossellonese, and Algherese. Each dialect can be further subdivided in several subdialects. The terms "Catalan" and "Valencian" (respectively used in Catalonia and the Valencian Community) refer to two varieties of the same language. There are two institutions regulating the two standard varieties, the Institute of Catalan Studies in Catalonia and the Valencian Academy of the Language in the Valencian Community. Central Catalan is considered the standard pronunciation of the language and has the highest number of speakers. It is spoken in the densely populated regions of the Barcelona province, the eastern half of the province of Tarragona, and most of the province of Girona. Catalan has an inflectional grammar. Nouns have two genders (masculine, feminine), and two numbers (singular, plural). Pronouns additionally can have a neuter gender, and some are also inflected for case and politeness, and can be combined in very complex ways. Verbs are split in several paradigms and are inflected for person, number, tense, aspect, mood, and gender. In terms of pronunciation, Catalan has many words ending in a wide variety of consonants and some consonant clusters, in contrast with many other Romance languages. Pronunciation Vowels Catalan has inherited the typical vowel system of Vulgar Latin, with seven stressed phonemes: , a common feature in Western Romance, except Spanish. Balearic has also instances of stressed . Dialects differ in the different degrees of vowel reduction, and the incidence of the pair . In Eastern Catalan (except Majorcan), unstressed vowels reduce to three: ; ; remains distinct. There are a few instances of unreduced , in some words. Algherese has lowered to . In Majorcan, unstressed vowels reduce to four: follow the Eastern Catalan reduction pattern; however reduce to , with remaining distinct, as in Western Catalan. In Western Catalan, unstressed vowels reduce to five: ; ; remain distinct. This reduction pattern, inherited from Proto-Romance, is also found in Italian and Portuguese. Some Western dialects present further reduction or vowel harmony in some cases. Central, Western, and Balearic differ in the lexical incidence of stressed and . Usually, words with in Central Catalan correspond to in Balearic and in Western Catalan. Words with in Balearic almost always have in Central and Western Catalan as well. As a result, Central Catalan has a much higher incidence of . Consonants Morphology Western Catalan: In verbs, the ending for 1st-person present indicative is in verbs of the 1st conjugation and -∅ in verbs of the 2nd and 3rd conjugations in most of the Valencian Community, or in all verb conjugations in the Northern Valencian Community and Western Catalonia.E.g. , , (Valencian); , , (Northwestern Catalan). Eastern Catalan: In verbs, the ending for 1st-person present indicative is , , or -∅ in all conjugations. E.g. (Central), (Balearic), and (Northern), all meaning ('I speak'). Western Catalan: In verbs, the inchoative endings are /, , , /. Eastern Catalan: In verbs, the inchoative endings are , , , . Western Catalan: In nouns and adjectives, maintenance of of medieval plurals in proparoxytone words.E.g. 'men', 'youth'. Eastern Catalan: In nouns and adjectives, loss of of medieval plurals in proparoxytone words.E.g. 'men', 'youth' (Ibicencan, however, follows the model of Western Catalan in this case). Vocabulary Despite its relative lexical unity, the two dialectal blocks of Catalan (Eastern and Western) show some differences in word choices. Any lexical divergence within any of the two groups can be explained as an archaism. Also, usually Central Catalan acts as an innovative element. Standards Standard Catalan, virtually accepted by all speakers, is mostly based on Eastern Catalan, which is the most widely used dialect. Nevertheless, the standards of the Valencian Community and the Balearics admit alternative forms, mostly traditional ones, which are not current in eastern Catalonia. The most notable difference between both standards is some tonic accentuation, for instance: (IEC) – (AVL). Nevertheless, AVL's standard keeps the grave accent , while pronouncing it as rather than , in some words like: ('what'), or . Other divergences include the use of (AVL) in some words instead of like in / ('almond'), / ('back'), the use of elided demonstratives ( 'this', 'that') in the same level as reinforced ones () or the use of many verbal forms common in Valencian, and some of these common in the rest of Western Catalan too, like subjunctive mood or inchoative conjugation in at the same level as or the priority use of morpheme in 1st person singular in present indicative ( verbs): instead of ('I buy'). In the Balearic Islands, IEC's standard is used but adapted for the Balearic dialect by the University of the Balearic Islands's philological section. In this way, for instance, IEC says it is correct writing as much as ('we sing') but the University says that the priority form in the Balearic Islands must be in all fields. Another feature of the Balearic standard is the non-ending in the 1st person singular present indicative: ('I buy'), ('I fear'), ('I sleep'). In Alghero, the IEC has adapted its standard to the Algherese dialect. In this standard one can find, among other features: the definite article instead of , special possessive pronouns and determinants ('mine'), ('his/her'), ('yours'), and so on, the use of in the imperfect tense in all conjugations: , , ; the use of many archaic words, usual words in Algherese: instead of ('less'), instead of ('someone'), instead of ('which'), and so on; and the adaptation of weak pronouns. In 2011, the Aragonese government passed a decree approving the statutes of a new language regulator of Catalan in La Franja (the so-called Catalan-speaking areas of Aragon) as originally provided for by Law 10/2009. The new entity, designated as , shall allow a facultative education in Catalan and a standardization of the Catalan language in La Franja. Status of Valencian Valencian is classified as a Western dialect, along with the northwestern varieties spoken in Western Catalonia (provinces of Lleida and the western half of Tarragona). Central Catalan has 90% to 95% inherent intelligibility for speakers of Valencian. Linguists, including Valencian scholars, deal with Catalan and Valencian as the same language. The official regulating body of the language of the Valencian Community, the Valencian Academy of Language (Acadèmia Valenciana de la Llengua, AVL) declares the linguistic unity between Valencian and Catalan varieties. The AVL, created by the Valencian parliament, is in charge of dictating the official rules governing the use of Valencian, and its standard is based on the Norms of Castelló (Normes de Castelló). Currently, everyone who writes in Valencian uses this standard, except the Royal Academy of Valencian Culture (Acadèmia de Cultura Valenciana, RACV), which uses for Valencian an independent standard. Despite the position of the official organizations, an opinion poll carried out between 2001 and 2004 showed that the majority of the Valencian people consider Valencian different from Catalan. This position is promoted by people who do not use Valencian regularly. Furthermore, the data indicates that younger generations educated in Valencian are much less likely to hold these views. A minority of Valencian scholars active in fields other than linguistics defends the position of the Royal Academy of Valencian Culture (Acadèmia de Cultura Valenciana, RACV), which uses for Valencian a standard independent from Catalan. This clash of opinions has sparked much controversy. For example, during the drafting of the European Constitution in 2004, the Spanish government supplied the EU with translations of the text into Basque, Galician, Catalan, and Valencian, but the latter two were identical. Vocabulary Word choices Despite its relative lexical unity, the two dialectal blocks of Catalan (Eastern and Western) show some differences in word choices. Any lexical divergence within any of the two groups can be explained as an archaism. Also, usually Central Catalan acts as an innovative element. Literary Catalan allows the use of words from different dialects, except those of very restricted use. However, from the 19th century onwards, there has been a tendency towards favoring words of Northern dialects to the detriment of others, Latin and Greek loanwords Like other languages, Catalan has a large list of loanwords from Greek and Latin. This process started very early, and one can find such examples in Ramon Llull's work. In the 14th and 15th centuries Catalan had a far greater number of Greco-Latin loanwords than other Romance languages, as is attested for example in Roís de Corella's writings. The incorporation of learned, or "bookish" words from its own ancestor language, Latin, into Catalan is arguably another form of lexical borrowing through the influence of written language and the liturgical language of the Church. Throughout the Middle Ages and into the early modern period, most literate Catalan speakers were also literate in Latin; and thus they easily adopted Latin words into their writing—and eventually speech—in Catalan. Word formation The process of morphological derivation in Catalan follows the same principles as the other Romance languages, where agglutination is common. Many times, several affixes are appended to a preexisting lexeme, and some sound alternations can occur, for example ("electrical") vs. . Prefixes are usually appended to verbs, as in ("foresee"). There is greater regularity in the process of word-compounding, where one can find compounded words formed much like those in English. Writing system Catalan uses the Latin script, with some added symbols and digraphs. The Catalan orthography is systematic and largely phonologically based. Standardization of Catalan was among the topics discussed during the First International Congress of the Catalan Language, held in Barcelona October 1906. Subsequently, the Philological Section of the Institut d'Estudis Catalans (IEC, founded in 1911) published the Normes ortogràfiques in 1913 under the direction of Antoni Maria Alcover and Pompeu Fabra. In 1932, Valencian writers and intellectuals gathered in Castelló de la Plana to make a formal adoption of the so-called Normes de Castelló, a set of guidelines following Pompeu Fabra's Catalan language norms. Grammar The grammar of Catalan is similar to other Romance languages. Features include: Use of definite and indefinite articles. Nouns, adjectives, pronouns, and articles are inflected for gender (masculine and feminine), and number (singular and plural). There is no case inflexion, except in pronouns. Verbs are highly inflected for person, number, tense, aspect, and mood (including a subjunctive). There are no modal auxiliaries. Word order is freer than in English. Gender and number inflection In gender inflection, the most notable feature is (compared to Portuguese, Spanish or Italian), the loss of the typical masculine suffix . Thus, the alternance of /, has been replaced by ø/. There are only a few exceptions, like / ("scarce"). Many not completely predictable morphological alternations may occur, such as: Affrication: / ("insane") vs. / ("ugly") Loss of : / ("flat") vs. / ("second") Final obstruent devoicing: / ("felt") vs. / ("said") Catalan has few suppletive couplets, like Italian and Spanish, and unlike French. Thus, Catalan has / ("boy"/"girl") and / ("cock"/"hen"), whereas French has / and /. There is a tendency to abandon traditionally gender-invariable adjectives in favor of marked ones, something prevalent in Occitan and French. Thus, one can find / ("boiling") in contrast with traditional /. As in the other Western Romance languages, the main plural expression is the suffix , which may create morphological alternations similar to the ones found in gender inflection, albeit more rarely. The most important one is the addition of before certain consonant groups, a phonetic phenomenon that does not affect feminine forms: / ("the pulse"/"the pulses") vs. / ("the dust"/"the dusts"). Determiners The inflection of determinatives is complex, specially because of the high number of elisions, but is similar to the neighboring languages. Catalan has more contractions of preposition + article than Spanish, like ("of + the [plural]"), but not as many as Italian (which has , , , etc.). Central Catalan has abandoned almost completely unstressed possessives (, etc.) in favor of constructions of article + stressed forms (, etc.), a feature shared with Italian. Personal pronouns The morphology of Catalan personal pronouns is complex, especially in unstressed forms, which are numerous (13 distinct forms, compared to 11 in Spanish or 9 in Italian). Features include the gender-neutral and the great degree of freedom when combining different unstressed pronouns (65 combinations). Catalan pronouns exhibit T–V distinction, like all other Romance languages (and most European languages, but not Modern English). This feature implies the use of a different set of second person pronouns for formality. This flexibility allows Catalan to use extraposition extensively, much more than French or Spanish. Thus, Catalan can have ("they recommended me to him"), whereas in French one must say , and Spanish . This allows the placement of almost any nominal term as a sentence topic, without having to use so often the passive voice (as in French or English), or identifying the direct object with a preposition (as in Spanish). Verbs Like all the Romance languages, Catalan verbal inflection is more complex than the nominal. Suffixation is omnipresent, whereas morphological alternations play a secondary role. Vowel alternances are active, as well as infixation and suppletion. However, these are not as productive as in Spanish, and are mostly restricted to irregular verbs. The Catalan verbal system is basically common to all Western Romance, except that most dialects have replaced the synthetic indicative perfect with a periphrastic form of ("to go") + infinitive. Catalan verbs are traditionally divided into three conjugations, with vowel themes , , , the last two being split into two subtypes. However, this division is mostly theoretical. Only the first conjugation is nowadays productive (with about 3500 common verbs), whereas the third (the subtype of , with about 700 common verbs) is semiproductive. The verbs of the second conjugation are fewer than 100, and it is not possible to create new ones, except by compounding. Syntax The grammar of Catalan follows the general pattern of Western Romance languages. The primary word order is subject–verb–object. However, word order is very flexible. Commonly, verb-subject constructions are used to achieve a semantic effect. The sentence "The train has arrived" could be translated as or . Both sentences mean "the train has arrived", but the former puts a focus on the train, while the latter puts a focus on the arrival. This subtle distinction is described as "what you might say while waiting in the station" versus "what you might say on the train." Catalan names In Spain, every person officially has two surnames, one of which is the father's first surname and the other is the mother's first surname. The law contemplates the possibility of joining both surnames with the Catalan conjunction i ("and"). Sample text Selected text from Manuel de Pedrolo's 1970 novel ("A love affair outside the city").

The Chad National Army ( Al-Jaish al-Watani at-Tshadi, ) consists of the five Defence and Security Forces listed in Article 185 of the Chadian Constitution that came into effect on 4 May 2018. These are the National Army ((including Ground Forces, and Air Force), the National Gendarmerie), the National Police, the National and Nomadic Guard (GNNT) and the Judicial Police. Article 188 of the Constitution specifies that National Defence is the responsibility of the Army, Gendarmerie and GNNT, whilst the maintenance of public order and security is the responsibility of the Police, Gendarmerie and GNNT. History From independence through the period of the presidency of Félix Malloum (1975–79), the official national army was known as the Chadian Armed Forces (Forces Armées Tchadiennes—FAT). Composed mainly of soldiers from southern Chad, FAT had its roots in the army recruited by France and had military traditions dating back to World War I. FAT lost its status as the legal state army when Malloum's civil and military administration disintegrated in 1979. Although it remained a distinct military body for several years, FAT was eventually reduced to the status of a regional army representing the south. After Habré consolidated his authority and assumed the presidency in 1982, his victorious army, the Armed Forces of the North (Forces Armées du Nord—FAN), became the nucleus of a new national army. The force was officially constituted in January 1983, when the various pro-Habré contingents were merged and renamed the Chadian National Armed Forces (Forces Armées Nationales Tchadiennes—FANT). The Military of Chad was dominated by members of Toubou, Zaghawa, Kanembou, Hadjerai, and Massa ethnic groups during the presidency of Hissène Habré. Later Chadian president Idriss Déby revolted and fled to the Sudan, taking with him many Zaghawa and Hadjerai soldiers in 1989. Chad's armed forces numbered about 36,000 at the end of the Habré regime, but swelled to an estimated 50,000 in the early days of Déby's rule. With French support, a reorganization of the armed forces was initiated early in 1991 with the goal of reducing its numbers and making its ethnic composition reflective of the country as a whole. Neither of these goals was achieved, and the military is still dominated by the Zaghawa. In 2004, the government discovered that many of the soldiers it was paying did not exist and that there were only about 19,000 soldiers in the army, as opposed to the 24,000 that had been previously believed. Government crackdowns against the practice are thought to have been a factor in a failed military mutiny in May 2004. The current conflict, in which the Chadian military is involved, is the civil war against Sudanese-backed rebels. Chad successfully manages to repel the rebel movements, but recently, with some losses (see Battle of N'Djamena (2008)). The army uses its artillery systems and tanks, but well-equipped insurgents have probably managed to destroy over 20 of Chad's 60 T-55 tanks, and probably shot down a Mi-24 Hind gunship, which bombed enemy positions near the border with Sudan. In November 2006 Libya supplied Chad with four Aermacchi SF.260W light attack planes. They are used to strike enemy positions by the Chadian Air Force, but one was shot down by rebels. During the last battle of N'Djamena gunships and tanks have been put to good use, pushing armed militia forces back from the Presidential palace. The battle impacted the highest levels of the army leadership, as Daoud Soumain, its Chief of Staff, was killed. On March 23, 2020 a Chadian army base was ambushed by fighters of the jihadist insurgent group Boko Haram. The army lost 92 servicemen in one day. In response, President Déby launched an operation dubbed "Wrath of Boma". According to Canadian counter terrorism St-Pierre, numerous external operations and rising insecurity in the neighboring countries had recently overstretched the capacities of the Chadian armed forces. After the death of President Idriss Déby on 19 April 2021 in fighting with FACT rebels, his son General Mahamat Idriss Déby was named interim president and head of the armed forces. Budget The CIA World Factbook estimates the military budget of Chad to be 4.2% of GDP as of 2006.. Given the then GDP ($7.095 bln) of the country, military spending was estimated to be about $300 million. This estimate however dropped after the end of the Civil war in Chad (2005–2010) to 2.0% as estimated by the World Bank for the year 2011. There aren't any more recent estimates available. External deployments UN missions non-UN missions Chad participated in a peace mission under the authority of African Union in the neighboring Central African Republic to try to pacify the recent conflict, but has chosen to withdraw after its soldiers were accused of shooting into a marketplace, unprovoked, according to BBC.

The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, million years ago. The name Carboniferous means "coal-bearing", from the Latin carbō ("coal") and ferō ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lineages such as temnospondyls, with the first appearance of amniotes, including synapsids (the group to which modern mammals belong) and reptiles during the late Carboniferous. The period is sometimes also called the Age of Amphibians, during which amphibians became dominant land vertebrates and diversified into many forms including lizard-like, snake-like, and crocodile-like. Insects would undergo a major radiation during the late Carboniferous. Vast swaths of forest covered the land, which would eventually be laid down and become the coal beds characteristic of the Carboniferous stratigraphy evident today. The later half of the period experienced glaciations, low sea level, and mountain building as the continents collided to form Pangaea. A minor marine and terrestrial extinction event, the Carboniferous rainforest collapse, occurred at the end of the period, caused by climate change. Etymology and history The term "Carboniferous" had first been used as an adjective by Irish geologist Richard Kirwan in 1799, and later used in a heading entitled "Coal-measures or Carboniferous Strata" by John Farey Sr. in 1811, becoming an informal term referring to coal-bearing sequences in Britain and elsewhere in Western Europe. Four units were originally ascribed to the Carboniferous, in ascending order, the Old Red Sandstone, Carboniferous Limestone, Millstone Grit and the Coal Measures. These four units were placed into a formalised Carboniferous unit by William Conybeare and William Phillips in 1822, and later into the Carboniferous System by Phillips in 1835. The Old Red Sandstone was later considered Devonian in age. Subsequently, separate stratigraphic schemes were developed in Western Europe, North America, and Russia. The first attempt to build an international timescale for the Carboniferous was during the Eighth International Congress on Carboniferous Stratigraphy and Geology in Moscow in 1975, when all of the modern ICS stages were proposed. Stratigraphy The Carboniferous is divided into two subsystems, the lower Mississippian and upper Pennsylvanian, which are sometimes treated as separate geological periods in North American stratigraphy. Stages can be defined globally or regionally. For global stratigraphic correlation, the International Commission on Stratigraphy (ICS) ratify global stages based on a Global Boundary Stratotype Section and Point (GSSP) from a single formation (a stratotype) identifying the lower boundary of the stage. The ICS subdivisions from youngest to oldest are as follows: ICS units The Mississippian was first proposed by Alexander Winchell, and the Pennsylvanian was proposed by J. J. Stevenson in 1888, and both were proposed as distinct and independent systems by H. S. Williams in 1881. The Tournaisian was named after the Belgian city of Tournai. It was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1832. The GSSP for the base of the Tournaisian is located at the La Serre section in Montagne Noire, southern France. It is defined by the first appearance datum of the conodont Siphonodella sulcata, which was ratified in 1990. However, the GSSP was later shown to have issues, with Siphonodella sulcata being shown to occur 0.45 m below the proposed boundary. The Viséan Stage was introduced by André Dumont in 1832. Dumont named this stage after the city of Visé in Belgium's Liège Province. The GSSP for the Visean is located in Bed 83 at the Pengchong section, Guangxi, southern China, which was ratified in 2012. The GSSP for the base of the Viséan is the first appearance datum of fusulinid (an extinct group of forams) Eoparastaffella simplex. The Serpukhovian Stage was proposed in 1890 by Russian stratigrapher Sergei Nikitin. It is named after the city of Serpukhov, near Moscow. The Serpukhovian Stage currently lacks a defined GSSP. The proposed definition for the base of the Serpukhovian is the first appearance of conodont Lochriea ziegleri. The Bashkirian was named after Bashkiria, the then Russian name of the republic of Bashkortostan in the southern Ural Mountains of Russia. The stage was introduced by Russian stratigrapher Sofia Semikhatova in 1934. The GSSP for the base of the Bashkirian is located at Arrow Canyon in Nevada, USA, which was ratified in 1996. The GSSP for the base of the Bashkirian is defined by the first appearance of the conodont Declinognathodus noduliferus. The Moscovian is named after Moscow, Russia, and was first introduced by Sergei Nikitin in 1890. The Moscovian currently lacks a defined GSSP. The Kasimovian is named after the Russian city of Kasimov, and originally included as part of Nikitin's original 1890 definition of the Moscovian. It was first recognised as a distinct unit by A.P. Ivanov in 1926, who named it the "Tiguliferina" Horizon after a kind of brachiopod. The Kasimovian currently lacks a defined GSSP. The Gzhelian is named after the Russian village of Gzhel (), nearby Ramenskoye, not far from Moscow. The name and type locality were defined by Sergei Nikitin in 1890. The base of the Gzhelian currently lacks a defined GSSP. The GSSP for the base of the Permian is located in the Aidaralash River valley near Aqtöbe, Kazakhstan, which was ratified in 1996. The beginning of the stage is defined by the first appearance of the conodont Streptognathodus postfusus. Regional stratigraphy North America In North American stratigraphy, the Mississippian is divided, in ascending order, into the Kinderhookian, Osagean, Meramecian and Chesterian series, while the Pennsylvanian is divided into the Morrowan, Atokan, Desmoinesian, Missourian and Virgilian series. The Kinderhookian is named after the village of Kinderhook, Pike County, Illinois. It corresponds to the lower part of the Tournasian. The Osagean is named after the Osage River in St. Clair County, Missouri. It corresponds to the upper part of the Tournaisian and the lower part of the Viséan. The Meramecian is named after the Meramec Highlands Quarry, located the near the Meramec River, southwest of St. Louis, Missouri. It corresponds to the mid Viséan. The Chesterian is named after the Chester Group, a sequence of rocks named after the town of Chester, Illinois. It corresponds to the upper Viséan and all of the Serpukhovian. The Morrowan is named after the Morrow Formation located in NW Arkansas, it corresponds to the lower Bashkirian. The Atokan was originally a formation named after the town of Atoka in southwestern Oklahoma. It corresponds to the upper Bashkirian and lower Moscovian The Desmoinesian is named after the Des Moines Formation found near the Des Moines River in central Iowa. It corresponds to the middle and upper Moscovian and lower Kasimovian. The Missourian was named at the same time as the Desmoinesian. It corresponds to the middle and upper Kasimovian. The Virgilian is named after the town of Virgil, Kansas, it corresponds to the Gzhelian. Europe The European Carboniferous is divided into the lower Dinantian and upper Silesian, the former being named for the Belgian city of Dinant, and the latter for the Silesia region of Central Europe. The boundary between the two subdivisions is older than the Mississippian-Pennsylvanian boundary, lying within the lower Serpukhovian. The boundary traditionally been as first appearance of the ammonoid Cravenoceras leion. In Europe, the Dinantian is primarily marine, the so-called "Carboniferous Limestone", while the Silesian primarily known for its coal measures. The Dinantian is divided up into two stages, the Tournaisian and Viséan. The Tournaisian is the same length as the ICS stage, but the Viséan is longer, extending into the lower Serpukhovian. The Silesian is divided into three stages, in ascending order, the Namurian, Westphalian, Stephanian. The Autunian, which corresponds to the middle and upper Gzhelian, is considered a part of the overlying Rotliegend. The Namurian is named after the city of Namur in Belgium. It corresponds to the middle and upper Serpukhovian and the lower Bashkirian. The Westphalian is named after the region of Westphalia in Germany it corresponds to the upper Bashkirian and all but the uppermost Moscovian. The Stephanian is named after the city of Saint-Étienne in eastern France. It corresponds to the uppermost Moscovian, the Kasimovian, and the lower Gzhelian. Palaeogeography A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread inland seas and the carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwanaland was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush swamps, later to become coal, flourished to within 30 degrees of the northernmost glaciers. Mid-Carboniferous, a drop in sea level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea level drop and the associated unconformity in North America separate the Mississippian Subperiod from the Pennsylvanian Subperiod. This happened about 323 million years ago, at the onset of the Permo-Carboniferous Glaciation. The Carboniferous was a time of active mountain-building as the supercontinent Pangaea came together. The southern continents remained tied together in the supercontinent Gondwana, which collided with North America–Europe (Laurussia) along the present line of eastern North America. This continental collision resulted in the Hercynian orogeny in Europe, and the Alleghenian orogeny in North America; it also extended the newly uplifted Appalachians southwestward as the Ouachita Mountains. In the same time frame, much of present eastern Eurasian plate welded itself to Europe along the line of the Ural Mountains. Most of the Mesozoic supercontinent of Pangea was now assembled, although North China (which would collide in the Latest Carboniferous), and South China continents were still separated from Laurasia. The Late Carboniferous Pangaea was shaped like an "O". There were two major oceans in the Carboniferous: Panthalassa and Paleo-Tethys, which was inside the "O" in the Carboniferous Pangaea. Other minor oceans were shrinking and eventually closed: the Rheic Ocean (closed by the assembly of South and North America), the small, shallow Ural Ocean (which was closed by the collision of Baltica and Siberia continents, creating the Ural Mountains), and the Proto-Tethys Ocean (closed by North China collision with Siberia/Kazakhstania). Climate Average global temperatures in the Early Carboniferous Period were high: approximately 20 °C (68 °F). However, cooling during the Middle Carboniferous reduced average global temperatures to about 12 °C (54 °F). Atmospheric carbon dioxide levels fell during the Carboniferous Period from roughly 8 times the current level in the beginning, to a level similar to today's at the end. The Carboniferous is considered part of the Late Paleozoic icehouse, which began in the latest Devonian, with the formation of small glaciers in Gondwana. During the Tournaisian the climate warmed, before cooling, there was another warm interval during the Viséan, but cooling began again during the early Serpukhovian. At the beginning of the Pennsylvanian around 323 million years ago, glaciers began to form around the South Pole, which would grow to cover a vast area of Gondwana. This area extended from the southern reaches of the Amazon basin and covered large areas of southern Africa, as well as most of Australia and Antarctica. Cyclothems, which began around 313 million years ago, and continue into the following Permian indicate that the size of the glaciers were controlled by Milankovitch cycles akin to recent ice ages, with glacial periods and interglacials. Deep ocean temperatures during this time were cold due to the influx of cold bottom waters generated by seasonal melting of the ice cap. The cooling and drying of the climate led to the Carboniferous Rainforest Collapse (CRC) during the late Carboniferous. Tropical rainforests fragmented and then were eventually devastated by climate change. Rocks and coal Carboniferous rocks in Europe and eastern North America largely consist of a repeated sequence of limestone, sandstone, shale and coal beds. In North America, the early Carboniferous is largely marine limestone, which accounts for the division of the Carboniferous into two periods in North American schemes. The Carboniferous coal beds provided much of the fuel for power generation during the Industrial Revolution and are still of great economic importance. The large coal deposits of the Carboniferous may owe their existence primarily to two factors. The first of these is the appearance of wood tissue and bark-bearing trees. The evolution of the wood fiber lignin and the bark-sealing, waxy substance suberin variously opposed decay organisms so effectively that dead materials accumulated long enough to fossilise on a large scale. The second factor was the lower sea levels that occurred during the Carboniferous as compared to the preceding Devonian Period. This promoted the development of extensive lowland swamps and forests in North America and Europe. Based on a genetic analysis of mushroom fungi, it was proposed that large quantities of wood were buried during this period because animals and decomposing bacteria and fungi had not yet evolved enzymes that could effectively digest the resistant phenolic lignin polymers and waxy suberin polymers. They suggest that fungi that could break those substances down effectively only became dominant towards the end of the period, making subsequent coal formation much rarer. The Carboniferous trees made extensive use of lignin. They had bark to wood ratios of 8 to 1, and even as high as 20 to 1. This compares to modern values less than 1 to 4. This bark, which must have been used as support as well as protection, probably had 38% to 58% lignin. Lignin is insoluble, too large to pass through cell walls, too heterogeneous for specific enzymes, and toxic, so that few organisms other than Basidiomycetes fungi can degrade it. To oxidize it requires an atmosphere of greater than 5% oxygen, or compounds such as peroxides. It can linger in soil for thousands of years and its toxic breakdown products inhibit decay of other substances. One possible reason for its high percentages in plants at that time was to provide protection from insects in a world containing very effective insect herbivores (but nothing remotely as effective as modern plant eating insects) and probably many fewer protective toxins produced naturally by plants than exist today. As a result, undegraded carbon built up, resulting in the extensive burial of biologically fixed carbon, leading to an increase in oxygen levels in the atmosphere; estimates place the peak oxygen content as high as 35%, as compared to 21% today. This oxygen level may have increased wildfire activity. It also may have promoted gigantism of insects and amphibians, creatures whose size is today limited by their respiratory systems' ability to transport and distribute oxygen at lower atmospheric concentrations. In eastern North America, marine beds are more common in the older part of the period than the later part and are almost entirely absent by the late Carboniferous. More diverse geology existed elsewhere, of course. Marine life is especially rich in crinoids and other echinoderms. Brachiopods were abundant. Trilobites became quite uncommon. On land, large and diverse plant populations existed. Land vertebrates included large amphibians. Life Plants Early Carboniferous land plants, some of which were preserved in coal balls, were very similar to those of the preceding Late Devonian, but new groups also appeared at this time. The main Early Carboniferous plants were the Equisetales (horse-tails), Sphenophyllales (scrambling plants), Lycopodiales (club mosses), Lepidodendrales (scale trees), Filicales (ferns), Medullosales (informally included in the "seed ferns", an artificial assemblage of a number of early gymnosperm groups) and the Cordaitales. These continued to dominate throughout the period, but during late Carboniferous, several other groups, Cycadophyta (cycads), the Callistophytales (another group of "seed ferns"), and the Voltziales (related to and sometimes included under the conifers), appeared. The Carboniferous lycophytes of the order Lepidodendrales, which are cousins (but not ancestors) of the tiny club-moss of today, were huge trees with trunks 30 meters high and up to 1.5 meters in diameter. These included Lepidodendron (with its cone called Lepidostrobus), Anabathra, Lepidophloios and Sigillaria. The roots of several of these forms are known as Stigmaria. Unlike present-day trees, their secondary growth took place in the cortex, which also provided stability, instead of the xylem. The Cladoxylopsids were large trees, that were ancestors of ferns, first arising in the Carboniferous. The fronds of some Carboniferous ferns are almost identical with those of living species. Probably many species were epiphytic. Fossil ferns and "seed ferns" include Pecopteris, Cyclopteris, Neuropteris, Alethopteris, and Sphenopteris; Megaphyton and Caulopteris were tree ferns. The Equisetales included the common giant form Calamites, with a trunk diameter of 30 to and a height of up to . Sphenophyllum was a slender climbing plant with whorls of leaves, which was probably related both to the calamites and the lycopods. Cordaites, a tall plant (6 to over 30 meters) with strap-like leaves, was related to the cycads and conifers; the catkin-like reproductive organs, which bore ovules/seeds, is called Cardiocarpus. These plants were thought to live in swamps. True coniferous trees (Walchia, of the order Voltziales) appear later in the Carboniferous, and preferred higher drier ground. Marine invertebrates In the oceans the marine invertebrate groups are the Foraminifera, corals, Bryozoa, Ostracoda, brachiopods, ammonoids, hederelloids, microconchids and echinoderms (especially crinoids). For the first time foraminifera take a prominent part in the marine faunas. The large spindle-shaped genus Fusulina and its relatives were abundant in what is now Russia, China, Japan, North America; other important genera include Valvulina, Endothyra, Archaediscus, and Saccammina (the latter common in Britain and Belgium). Some Carboniferous genera are still extant. The first true priapulids appeared during this period. The microscopic shells of radiolarians are found in cherts of this age in the Culm of Devon and Cornwall, and in Russia, Germany and elsewhere. Sponges are known from spicules and anchor ropes, and include various forms such as the Calcispongea Cotyliscus and Girtycoelia, the demosponge Chaetetes, and the genus of unusual colonial glass sponges Titusvillia. Both reef-building and solitary corals diversify and flourish; these include both rugose (for example, Caninia, Corwenia, Neozaphrentis), heterocorals, and tabulate (for example, Chladochonus, Michelinia) forms. Conularids were well represented by Conularia Bryozoa are abundant in some regions; the fenestellids including Fenestella, Polypora, and Archimedes, so named because it is in the shape of an Archimedean screw. Brachiopods are also abundant; they include productids, some of which (for example, Gigantoproductus) reached very large (for brachiopods) size and had very thick shells, while others like Chonetes were more conservative in form. Athyridids, spiriferids, rhynchonellids, and terebratulids are also very common. Inarticulate forms include Discina and Crania. Some species and genera had a very wide distribution with only minor variations. Annelids such as Serpulites are common fossils in some horizons. Among the mollusca, the bivalves continue to increase in numbers and importance. Typical genera include Aviculopecten, Posidonomya, Nucula, Carbonicola, Edmondia, and Modiola. Gastropods are also numerous, including the genera Murchisonia, Euomphalus, Naticopsis. Nautiloid cephalopods are represented by tightly coiled nautilids, with straight-shelled and curved-shelled forms becoming increasingly rare. Goniatite ammonoids such as Aenigmatoceras are common. Trilobites are rarer than in previous periods, on a steady trend towards extinction, represented only by the proetid group. Ostracoda, a class of crustaceans, were abundant as representatives of the meiobenthos; genera included Amphissites, Bairdia, Beyrichiopsis, Cavellina, Coryellina, Cribroconcha, Hollinella, Kirkbya, Knoxiella, and Libumella. Amongst the echinoderms, the crinoids were the most numerous. Dense submarine thickets of long-stemmed crinoids appear to have flourished in shallow seas, and their remains were consolidated into thick beds of rock. Prominent genera include Cyathocrinus, Woodocrinus, and Actinocrinus. Echinoids such as Archaeocidaris and Palaeechinus were also present. The blastoids, which included the Pentreinitidae and Codasteridae and superficially resembled crinoids in the possession of long stalks attached to the seabed, attain their maximum development at this time. Freshwater and lagoonal invertebrates Freshwater Carboniferous invertebrates include various bivalve molluscs that lived in brackish or fresh water, such as Anthraconaia, Naiadites, and Carbonicola; diverse crustaceans such as Candona, Carbonita, Darwinula, Estheria, Acanthocaris, Dithyrocaris, and Anthrapalaemon. The eurypterids were also diverse, and are represented by such genera as Adelophthalmus, Megarachne (originally misinterpreted as a giant spider, hence its name) and the specialised very large Hibbertopterus. Many of these were amphibious. Frequently a temporary return of marine conditions resulted in marine or brackish water genera such as Lingula, Orbiculoidea, and Productus being found in the thin beds known as marine bands. Terrestrial invertebrates Fossil remains of air-breathing insects, myriapods and arachnids are known from the late Carboniferous, but so far not from the early Carboniferous. Their diversity when they do appear, however, shows that these arthropods were both well-developed and numerous. Their large size can be attributed to the moistness of the environment (mostly swampy fern forests) and the fact that the oxygen concentration in the Earth's atmosphere in the Carboniferous was much higher than today. This required less effort for respiration and allowed arthropods to grow larger with the up to millipede-like Arthropleura being the largest-known land invertebrate of all time. Among the insect groups are the huge predatory Protodonata (griffinflies), among which was Meganeura, a giant dragonfly-like insect and with a wingspan of ca. —the largest flying insect ever to roam the planet. Further groups are the Syntonopterodea (relatives of present-day mayflies), the abundant and often large sap-sucking Palaeodictyopteroidea, the diverse herbivorous Protorthoptera, and numerous basal Dictyoptera (ancestors of cockroaches). Many insects have been obtained from the coalfields of Saarbrücken and Commentry, and from the hollow trunks of fossil trees in Nova Scotia. Some British coalfields have yielded good specimens: Archaeoptilus, from the Derbyshire coalfield, had a large wing with preserved part, and some specimens (Brodia) still exhibit traces of brilliant wing colors. In the Nova Scotian tree trunks land snails (Archaeozonites, Dendropupa) have been found. Fish Many fish inhabited the Carboniferous seas; predominantly Elasmobranchs (sharks and their relatives). These included some, like Psammodus, with crushing pavement-like teeth adapted for grinding the shells of brachiopods, crustaceans, and other marine organisms. Other sharks had piercing teeth, such as the Symmoriida; some, the petalodonts, had peculiar cycloid cutting teeth. Most of the sharks were marine, but the Xenacanthida invaded fresh waters of the coal swamps. Among the bony fish, the Palaeonisciformes found in coastal waters also appear to have migrated to rivers. Sarcopterygian fish were also prominent, and one group, the Rhizodonts, reached very large size. Most species of Carboniferous marine fish have been described largely from teeth, fin spines and dermal ossicles, with smaller freshwater fish preserved whole. Freshwater fish were abundant, and include the genera Ctenodus, Uronemus, Acanthodes, Cheirodus, and Gyracanthus. Chondrichthyes (especially the Stethacanthids) underwent a major evolutionary radiation during the Carboniferous. It is believed that this evolutionary radiation occurred because the decline of the placoderms at the end of the Devonian Period caused many environmental niches to become unoccupied and allowed new organisms to evolve and fill these niches. As a result of the evolutionary radiation Carboniferous sharks assumed a wide variety of bizarre shapes including Stethacanthus which possessed a flat brush-like dorsal fin with a patch of denticles on its top. Stethacanthus unusual fin may have been used in mating rituals. Tetrapods Carboniferous amphibians were diverse and common by the middle of the period, more so than they are today; some were as long as 6 meters, and those fully terrestrial as adults had scaly skin. They included a number of basal tetrapod groups classified in early books under the Labyrinthodontia. These had long bodies, a head covered with bony plates and generally weak or undeveloped limbs. The largest were over 2 meters long. They were accompanied by an assemblage of smaller amphibians included under the Lepospondyli, often only about long. Some Carboniferous amphibians were aquatic and lived in rivers (Loxomma, Eogyrinus, Proterogyrinus); others may have been semi-aquatic (Ophiderpeton, Amphibamus, Hyloplesion) or terrestrial (Dendrerpeton, Tuditanus, Anthracosaurus). The Carboniferous Rainforest Collapse slowed the evolution of amphibians who could not survive as well in the cooler, drier conditions. Amniotes, however, prospered due to specific key adaptations. One of the greatest evolutionary innovations of the Carboniferous was the amniote egg, which allowed the laying of eggs in a dry environment, as well as keratinized scales and claws, allowing for the further exploitation of the land by certain tetrapods. These included the earliest sauropsid reptiles (Hylonomus), and the earliest known synapsid (Archaeothyris). Synapsids quickly became huge and diversified in the Permian, only for their dominance to stop during the Mesozoic Era. Sauropsids (reptiles, and also, later, birds) also diversified but remained small until the Mesozoic, during which they would dominate the land, as well as the water and sky. Reptiles underwent a major evolutionary radiation in response to the drier climate that preceded the rainforest collapse. By the end of the Carboniferous Period, amniotes had already diversified into a number of groups, including several families of synapsid pelycosaurs, protorothyridids, captorhinids, saurians and araeoscelids. Fungi As plants and animals were growing in size and abundance in this time (for example, Lepidodendron), land fungi diversified further. Marine fungi still occupied the oceans. All modern classes of fungi were present in the Late Carboniferous (Pennsylvanian Epoch). During the Carboniferous, animals and bacteria had great difficulty with processing the lignin and cellulose that made up the gigantic trees of the period. Microbes had not evolved that could process them. The trees, after they died, simply piled up on the ground, occasionally becoming part of long-running wildfires after a lightning strike, with others very slowly degrading into coal. White rot fungus were the first organisms to be able to process these and break them down in any reasonable quantity and timescale. Thus, some have proposed that fungi helped end the Carboniferous Period, stopping accumulation of undegraded plant matter, although this idea remains highly controversial. Extinction events Romer's gap The first 15 million years of the Carboniferous had very limited terrestrial fossils. This gap in the fossil record is called Romer's gap after the American palaentologist Alfred Romer. While it has long been debated whether the gap is a result of fossilisation or relates to an actual event, recent work indicates the gap period saw a drop in atmospheric oxygen levels, indicating some sort of ecological collapse. The gap saw the demise of the Devonian fish-like ichthyostegalian labyrinthodonts, and the rise of the more advanced temnospondyl and reptiliomorphan amphibians that so typify the Carboniferous terrestrial vertebrate fauna. Carboniferous rainforest collapse Before the end of the Carboniferous Period, an extinction event occurred. On land this event is referred to as the Carboniferous Rainforest Collapse (CRC). Vast tropical rainforests collapsed suddenly as the climate changed from hot and humid to cool and arid. This was likely caused by intense glaciation and a drop in sea levels. The new climatic conditions were not favorable to the growth of rainforest and the animals within them. Rainforests shrank into isolated islands, surrounded by seasonally dry habitats. Towering lycopsid forests with a heterogeneous mixture of vegetation were replaced by much less diverse tree-fern dominated flora. Amphibians, the dominant vertebrates at the time, fared poorly through this event with large losses in biodiversity; reptiles continued to diversify due to key adaptations that let them survive in the drier habitat, specifically the hard-shelled egg and scales, both of which retain water better than their amphibian counterparts.

The politics of Cameroon takes place in a framework of a unitary presidential republic, whereby the President of Cameroon is both head of state and head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly of Cameroon. Political background The government adopted legislation in 1997 to authorize the formation of multiple political parties and ease restrictions on forming civil associations and private newspapers. Cameroon's first multiparty legislative and presidential elections were held in 1992 followed by municipal elections in 1996 and another round of legislative and presidential elections in 1997. Because the government refused to consider opposition demands for an independent election commission, the three major opposition parties boycotted the October 1997 presidential election, which Biya easily won. The leader of one of the opposition parties, Bello Bouba Maigari of the NUDP, subsequently joined the government. Cameroon has a number of independent newspapers. Censorship was abolished in 1996, but the government sometimes seizes or suspends newspapers and occasionally arrests journalists. Although a 1990 law authorizes private radio and television stations, the government has not granted any licenses as of March 1998. The Cameroonian Government's human rights record has been improving over the years but remains flawed. There continue to be reported abuses, including beatings of detainees, arbitrary arrests, and illegal searches. The judiciary is frequently corrupt, inefficient, and subject to political influence. Worthy of note is the fact that Cameroon is the only country in which two Constitutions are applicable side by side. For example, the 1972 Constitution designates the Prime Minister as constitutional successor of the Head of State in case of incapacity, death, resignation or unaccountable absence of the incumbent. Contrarily, the 1996 Constitutional Reform designates the President of the Senate as constitutional successor; but the Senate (provided for by 1996 Reform) does not exist. Apart from increasing the presidential mandate from 5 years to 7 years, very few amendments of the 1996 Constitutional Reform have been applied. Executive branch |President |Paul Biya |Cameroon People's Democratic Movement |6 November 1982 |- |Prime Minister |Joseph Dion Ngute |Cameroon People's Democratic Movement |4 January 2019 |} The 1972 constitution of the Republic of Cameroon as modified by 1996 reforms provides for a strong central government dominated by the executive. The president is empowered to name and dismiss cabinet members (regardless of parliamentary representation), judges, generals, provincial governors, prefects, sub-prefects, and heads of Cameroon's parastatal (about 100 state-controlled) firms, obligate or disburse expenditures, approve or veto regulations, declare states of emergency, and appropriate and spend profits of parastatal firms. The president is not required to consult the National Assembly. In 2008, a constitutional amendment was passed that eliminated term limits for president. The judiciary is subordinate to the executive branch's Ministry of Justice. The Supreme court may review the constitutionality of a law only at the president's request. All local government officials are employees of the central government's Ministry of Territorial Administration, from which local governments also get most of their budgets. While the president, the minister of justice, and the president's judicial advisers (the Supreme Court) top the judicial hierarchy, traditional rulers, courts, and councils also exercise functions of government. Traditional courts still play a major role in domestic, property, and probate law. Tribal laws and customs are honored in the formal court system when not in conflict with national law. Traditional rulers receive stipends from the national government. Legislative branch The 180-member National Assembly meets in ordinary session three times a year (March/April, June/July, and November/December), and has seldom, until recently, made major changes in legislation proposed by the executive. Laws are adopted by majority vote of members present or, if the president demands a second reading, of a total membership. Following government pledges to reform the strongly centralized 1972 constitution, the National Assembly adopted a number of amendments in December 1995 which were promulgated in January 1996. The amendments call for the establishment of a 100-member senate as part of a bicameral legislature, the creation of regional councils, and the fixing of the presidential term to 7 years, renewable once. One-third of senators are to be appointed by the President, and the remaining two-thirds are to be chosen by indirect elections. The government has established the Senate in 2013. Political parties and elections Judicial branch The judiciary is subordinate to the executive branch's Ministry of Justice. The Supreme Court may review the constitutionality of a law only at the president's request. The role of women In an article on the construction of a ‘model Cameroonian woman’ in the Cameroonian parliament, Lilian Atanga, examines arguments used to perpetuate a popular ideal and discourses which "sustain and maintain the status quo (e.g. of women as domestic or women as cooks)".

President François Bozizé has said that one of his priorities is to get the support of the international community. This has indeed been visible in his relations to donor countries and international organisations. At the same time it is difficult to have an open policy towards neighbouring countries when they are used as safe haven by rebels regularly attacking Central African Republic (C.A.R.), or when one allied country is in war with another (as is Chad–Sudan). The Central African Armed Forces cannot–even with the support of France and the Multinational Force of the Economic and Monetary Community of Central Africa (FOMUC)–exert control over its own borders. Hence, armed groups are regularly entering the country from Chad and Sudan. The President said in an interview that he has a good relation with neighbours and fellow CEMAC countries, "put aside the incident with Sudan when the border had to be closed since militia entered C.A.R. territory". Participation in international organisations The Central African Republic is an active member in several Central African organizations, including the Economic and Monetary Union (CEMAC), the Economic Community of Central African States (CEEAC), the Central African Peace and Security Council (COPAX- still under formation), and the Central Bank of Central African States (BEAC). Standardization of tax, customs, and security arrangements between the Central African states is a major foreign policy objective of the C.A.R. Government. The C.A.R. is a participant in the Community of Sahel–Saharan States (CEN-SAD), and the African Union (AU). Other multilateral organizations—including the World Bank, International Monetary Fund, United Nations agencies, European Union, and the African Development Bank—and bilateral donors—including Germany, Japan, the European Union, and the United States—are significant development partners for the C.A.R. Bilateral relations Nineteen countries have resident diplomatic representatives in Bangui, and the C.A.R. maintains approximately the same number of missions abroad. Since early 1989 the government recognizes both Israel and the Palestinian state. The C.A.R. also maintains diplomatic relations with the People's Republic of China. The C.A.R. generally joins other African and developing country states in consensus positions on major policy issues. The most important countries the C.A.R. maintains bilateral relations include the following.

Ivory Coast invested remarkably in its transport system. Transport Infrastructures are much more developed than they are other West African countries despite a crisis that restrained their maintenance and development. Since its independence in 1960, Ivory Coast put an emphasis on increasing and modernizing the transport network for human as well as for goods. Major infrastructures of diverse nature were built including railways, roads, waterways, and airports. In spite of the crisis, neighbor countries (Burkina Faso, Mali, Niger, and Guinea) still strongly depend on the Ivorian transport network for importing, exporting, and transiting their immigrants to Ivory Coast. Rail transport The nation's railway system is part of a 1 260 km long route that links the country to Burkina Faso and Niger. 1 156 km of railroad links Abidjan to Ouagadougou, capital of Burkina Faso. Built during colonial era by the firm Abidjan-Niger (RAN), this railroad freed several landlocked countries among which were ex-Upper-Volta (Burkina Faso), Niger, and Mali. This railroad, operated by Sitarail, plays a key role as regards to the carriage of the goods (livestock) and the transport of people between Ivory Coast and border countries: 1 million tons of goods have transited in 2006. In 2005, despite the negative impact the crisis had on the sector, benefits engendered by transporting the goods and people via RAN, are estimated respectively at 16 309 et3 837billionCFA. As of 2004, the railway network consisted of a state-controlled 660 km section of a 1,146 km narrow gauge railroad that ran north from Abidjan through Bouaké and Ferkéssédougou to Ouagadougou, Burkina Faso. Road transport Ivory Coast road network spreads over 85 000 km consisting of 75 000 unpaved, 65 000 km, and 224 km highways. It provides national and international traffic with neighbor countries. The Trans–West African Coastal Highway provides a paved link to Ghana, Togo, Benin and Nigeria, with paved highways to landlocked Mali and Burkina Faso feeding into the coastal highway. When construction of roads and bridges in Liberia and Sierra Leone is complete, the highway will link to another seven Economic Community of West African States (ECOWAS) nations to the west and north-west. At the national level, vehicles are estimated at 600 000, which includes 75% of used cars (second hand) due to the low purchasing power since the beginning of the economic crisis. 20 000 new cars are registered every year. Although maintenance and renovations works are being carried out since middle-2011, over 80% of the Ivorian network is older than 20 years and therefore damaged. In addition, a significant traffic exists throughout Abidjan, the capital. This traffic is mainly composed of taxi, buses and mini-buses locally referred to as Gbaka. The country counts with two 4-laned motorways, the first one running from Abidjan to Yamoussoukro for a length of 224 km., and the second joining Abidjan to Grand-Bassam, with a length of 30 km. Both are built with modern technologies and under international standards of security. Maritime transport Landscape view of the Autonomous Port of Abidjan Ivory Coast greatly contributed to developing maritime transport by building two ports on its seaside namely, autonomous port of Abidjan, sometimes referred to as "lung of Ivorian economy", and the San-Pedro port. The total traffic in 2005, by adding importation to exportation, was 18 661 784 tons for autonomous port of Abidjan and 1 001 991 tons for San-Pedro. The autonomous port of Abidjan cover a 770 hectares area and shelters 60% of the country industries. It is the first tuna fishing port in Africa. It contains 36 conventional berths spread over six kilometers of quays providing a capacity of sixty commercial ships with multiple special docks, a container terminal as well as several specialized and industrial berths. The other major port, the San-Pedro port, operates since 1971 and has two quays covering 18,727 m2 area. Apart from those two major ports, there are also small ports at Sassandra, Aboisso, and Dabou. Air transport Ivory Coast has three international airports located in Abidjan, Yamoussoukro, and Bouaké. Fourteen smaller cities also possess regional airports, the most important of which are Daloa, Korhogo, Man, Odiénné and San-pédro. Twenty-seven aerodromes exists and are operated by a public establishment, the Anam (National agency for civil aviation and meteorology), except the activities carried out by the Asecna (Agency for security of air fret in Africa and Madagascar). Since the outbreak of the crisis, only five of these airports are available. These are Abidjan, San-Pédro, Yamoussoukro, Daloa, and Touba. Regarding the International Airport of Abidjan, official statistics from 2005, showed 14 257 commercial movements (departures and arrivals); 745 180 commercial passengers (arrivals, departures, and transit) and 12 552 tons of commercial fret. The Airport of Abidjan covers 90% of the air traffic of Côte d'Ivoire and generate 95% of the overall profits of the sector. The airport of Abidjan is operated by a private company, Aeria, created in association with the Commerce Chamber of Marseilles. Its traffic mainly encompasses European aeronautical companies (Air France, Brussels Airlines) and some African firms (South African Airways, Kenya Airways, Air Sénégal International). References

Cypress Hill is an American hip hop group from South Gate, California. They are the first hip-hop group to have sold multi-platinum and platinum albums, having sold over 20 million albums worldwide. They are considered to be among the main progenitors of West Coast and 1990s hip hop. The group has been critically acclaimed for their first five albums. All of the group members advocate for medical and recreational use of cannabis in the United States. In 2019, Cypress Hill became the first hip hop group to have a star on the Hollywood Walk of Fame. History Formation (1988) Senen Reyes (also known as Sen Dog) and Ulpiano Sergio Reyes (also known as Mellow Man Ace) are brothers born in Pinar del Río, Cuba. In 1971, their family immigrated to the United States and initially lived in South Gate, California. In 1988, the two brothers teamed up with New York City native Lawrence Muggerud (also known as DJ Muggs, previously in a rap group named 7A3) and Louis Freese (also known as B-Real) to form a hip-hop group named DVX (Devastating Vocal Excellence). The band soon lost Mellow Man Ace to a solo career, and changed their name to Cypress Hill, after a street in South Gate. Early works and mainstream success (1989–1996) After recording a demo in 1989, Cypress Hill signed a record deal with Ruffhouse Records. Their self-titled first album was released in August 1991. The lead single was the double A-side "The Phuncky Feel One"/"How I Could Just Kill a Man" which received heavy airplay on urban and college radio, most notably peaking at #1 on Billboard Hot Rap Tracks chart. The other two singles released from the album were "Hand on the Pump" and "Latin Lingo", the latter of which combined English and Spanish lyrics, a trait that was continued throughout their career. The success of these singles led to the album selling two million copies in the U.S. alone. In 1992, Cypress Hill's first contribution to a soundtrack was the song "Shoot 'Em Up" for the movie Juice. The group made their first appearance at Lollapalooza on the side stage in 1992. It was the festival's second year of touring, and featured a diverse lineup of acts such as Red Hot Chili Peppers, Ice Cube, Lush, Tool, Stone Temple Pilots, among others. Black Sunday, the group's second album, debuted at number one on the Billboard 200 in 1993, recording the highest Soundscan for a rap group up until that time. Also, with their debut still in the charts, they became the first rap group to have two albums in the top 10 of the Billboard 200 at the same time. With "Insane in the Brain" becoming a crossover hit, the album went triple platinum in the U.S. and sold about 3.26 million copies. "Insane in the Brain" also garnered the group their first Grammy nomination. Cypress Hill headlined the Soul Assassins tour with House of Pain and Funkdoobiest as support, then performed on a college tour with Rage Against the Machine and Seven Year Bitch. In 1993, Cypress Hill also had two tracks on the Judgment Night soundtrack, teaming up with Pearl Jam (without vocalist Eddie Vedder) on the track "Real Thing" and Sonic Youth on "I Love You Mary Jane". The soundtrack was notable for intentionally creating collaborations between the rap/hip-hop and rock/metal genres, and as a result the soundtrack peaked at #17 on the Billboard 200. The group later played at Woodstock 94, introducing new member Eric Bobo, son of Willie Bobo and formerly a percussionist with the Beastie Boys. That same year, Rolling Stone named the group as the Best Rap Group in their music awards voted by critics and readers. Cypress Hill then played at Lollapalooza for two successive years, topping the bill in 1995. They also appeared on the "Homerpalooza" episode of The Simpsons. The group received their second Grammy nomination in 1995 for "I Ain't Goin' Out Like That". Cypress Hill's third album III: Temples of Boom was released in 1995 as it peaked at #3 on the Billboard 200 and #3 on the Canadian Albums Chart. The album was certified platinum by the RIAA. "Throw Your Set in the Air" was the most successful single off the album, peaking at #45 on the Billboard Hot 100 and #11 on the Hot Rap Tracks charts. The single also earned Cypress Hill's third Grammy nomination. Afterwards, Sen Dog took a break from the group to form a Los Angeles-based rap rock band, SX-10. Meanwhile, in 1996, Cypress Hill appeared on the first Smokin' Grooves tour, featuring Ziggy Marley, The Fugees, Busta Rhymes, and A Tribe Called Quest. The group also released a nine track EP Unreleased and Revamped with rare mixes. Continued success, crossover appeal, and Stoned Raiders (1997–2002) In 1997, the members focused on their solo careers. DJ Muggs released Soul Assassins: Chapter 1, with features from Dr. Dre, KRS-One, Wyclef Jean, and Mobb Deep. B-Real appeared with Busta Rhymes, Coolio, LL Cool J, and Method Man on "Hit 'Em High" from the multi-platinum Space Jam Soundtrack. He also appeared with RBX, Nas, and KRS-One on "East Coast Killer, West Coast Killer" from Dr. Dre's Dr. Dre Presents the Aftermath album, and contributed to an album entitled The Psycho Realm with the group of the same name. Sen Dog also released the Get Wood sampler as part of SX-10 on the label Flip Records. In addition, Eric Bobo contributed drums to various rock bands on their albums, such as 311 and Soulfly. Cypress Hill released IV in 1998 which went gold in the US. The lead single off the album was "Dr. Greenthumb", as it peaked at #11 on the Hot Rap Tracks chart. It also peaked at #70 on the Billboard Hot 100, their last appearance on the chart to date. In 1999, Cypress Hill helped with the PC first-person shooter video game Kingpin: Life of Crime. Three of the band's songs from the 1998 IV album were in the game, "16 Men Till There's No Men Left", "Checkmate", and "Lightning Strikes". The group also did voice work for some of the game's characters. Also in 1999, the band released a greatest hits album in Spanish, Los Grandes Éxitos en Español. In 2000, Cypress Hill then fused genres with their fifth album, Skull & Bones, which consisted of two discs. The first disc Skull was composed of rap tracks while Bones explored further the group's forays into rock. The album peaked at #5 on the Billboard 200 and at #3 on the Canadian Albums Chart. The first two singles were "(Rock) Superstar" for rock radio and "(Rap) Superstar" for urban radio. Both singles received heavy airplay on both rock and urban radio, enabling Cypress Hill to crossover again. Following the release of Skull & Bones, Cypress Hill and MxPx landed a slot opening for The Offspring on the Conspiracy of One Tour. The group also released Live at the Fillmore, a concert disc recorded at San Francisco's The Fillmore in 2000. Cypress Hill continued their experimentation with rock on the Stoned Raiders album in 2001; however, its sales were a disappointment. The album peaked at #64 on the Billboard 200, the group's lowest position to that point. Also in 2001, the group made a cameo appearance as themselves in the film How High. Cypress Hill then recorded the track "Just Another Victim" for WWF as a theme song for Tazz, borrowing elements from the 2000 single "(Rock) Superstar". The song would later be featured on the compilation WWF Forceable Entry in March 2002. Till Death Do Us Part, DJ Muggs' hiatus, and Rise Up (2003–2012) Cypress Hill released Till Death Do Us Part in March 2004. It featured appearances by Bob Marley's son Damian Marley, Prodigy of Mobb Deep, and producers The Alchemist and Fredwreck. The album represented a further departure from the group's signature sound. Reggae was a strong influence on its sound, especially on the lead single "What's Your Number?". The track featured Tim Armstrong of Rancid on guitar and backup vocals. It was based on the classic song "The Guns of Brixton" from The Clash's album London Calling. "What's Your Number?" saw Cypress Hill crossover into the rock charts again, as the single peaked at #23 on the Modern Rock Tracks chart. Afterwards, DJ Muggs took a hiatus from the group to focus on other projects, such as Soul Assassins and his DJ Muggs vs. collaboration albums. In December 2005 another compilation album titled Greatest Hits From the Bong was released. It included nine hits from previous albums and two new tracks. In the summer of 2006, B-Real appeared on Snoop Dogg's single "Vato", which was produced by Pharrell Williams. The group's next album was tentatively scheduled for an early 2007 release, but it was pushed back numerous times. In 2007 Cypress Hill toured as a part of the Rock the Bells tour. They headlined with Public Enemy, Wu-Tang Clan, Nas, and a reunited Rage Against the Machine. On July 25, 2008, Cypress Hill performed at a benefit concert at the House of Blues Chicago, where a majority of the proceeds went to the Chicago Alliance to End Homelessness. In August 2009, a new song by Cypress Hill titled "Get 'Em Up" was made available on iTunes. The song was also featured in the Madden NFL 2010 video game. It was the first sampling of the group's then-upcoming album. Cypress Hill's eighth studio album Rise Up featured contributions from Everlast, Tom Morello, Daron Malakian, Pitbull, Marc Anthony, and Mike Shinoda. Previously, the vast majority of the group's albums were produced by DJ Muggs; however, Rise Up instead featured a large array of guest features and producers, with DJ Muggs only appearing on two tracks. The album was released on Priority Records/EMI Entertainment, as the group was signed to the label by new creative chairman Snoop Dogg. The album was released on April 20, 2010. The single "Rise Up" was featured at WWE's pay-per-view Elimination Chamber as the official theme song for the event. The song managed to peak at #20 on the Modern Rock Tracks chart. It also appeared in the trailer for the movie The Green Hornet. Cypress Hill commenced its Rise Up tour in Philadelphia on April 10, 2010. In one particular instance, the group was supposed to stop in Tucson, Arizona but canceled the show in protest of the recent immigration legislation. At the Rock en Seine festival in Paris on August 27, 2010, they had said in an interview that they would anticipate the outcome of the legislation before returning. Also in 2010, Cypress Hill performed at the Reading and Leeds Festivals on August 28 at Leeds and August 29 at Reading. On June 5, 2012, Cypress Hill and dubstep artist Rusko released a collaborative EP entitled Cypress X Rusko. DJ Muggs, who was still on a hiatus, and Eric Bobo were absent on the release. Also in 2012, Cypress Hill collaborated with Deadmau5 on his sixth studio album Album Title Goes Here, lending vocals on "Failbait". Elephants on Acid, Hollywood Walk of Fame, and Back in Black (2013–present) During the interval between Cypress Hill albums, the four members commenced work on various projects. B-Real formed the band Prophets of Rage alongside three members of Rage Against the Machine and two members of Public Enemy. He also released The Prescription EP under his Dr. Greenthumb persona. Sen Dog formed the band Powerflo alongside members of Fear Factory, downset., and Biohazard. DJ Muggs revived his Soul Assassins project as its main producer. Eric Bobo formed a duo named Ritmo Machine. He also contributed to an unreleased album by his father Willie Bobo. On September 28, 2018, Cypress Hill released the album Elephants on Acid, which saw the return of DJ Muggs as main composer and producer. It peaked at #120 on the Billboard 200. Overall, four different singles were released to promote the album. In April 2019 Cypress Hill received a star on the Hollywood Walk of Fame. They became the first Latin-American group to receive a star. In January 2022, the group announced the release date of their 10th studio album entitled Back in Black. The album is slated to be released on March 18, 2022. In addition, Cypress Hill will support the album by joining Slipknot alongside Ho99o9 for the second half of the 2022 Knotfest Roadshow. They had previously invited Slipknot to join their Great Smoke-Out festival back in 2009. Style Rapping One of the band's most striking aspects is B-Real's exaggeratedly high-pitched nasal vocals. In the book Check the Technique, B-Real described his nasal style, saying his rapping voice is "high and annoying...the nasal style I have was just something that I developed...my more natural style wasn't so pleasing to DJ Muggs and Sen Dog's ears" and talking about the nasal style in the book How to Rap, B-Real said "you want to stand out from the others and just be distinct...when you got something that can separate you from everybody else, you gotta use it to your advantage." In the film Art of Rap, B-Real credited the Beastie Boys as an influence when developing his rapping style. Sen Dog's voice is deeper, more violent, and often shouted alongside the rapping; his vocals are often emphasized by adding another background/choir voice to say them. Sen Dog's style is in contrast to B-Real's, who said "Sen's voice is so strong" and "it all blends together" when they are both on the same track. Both B-Real and Sen Dog started writing lyrics in both Spanish and English. Initially, B-Real was inspired to start writing raps from watching Sen Dog and Mellow Man Ace writing their lyrics, and originally B-Real was going to just be the writer for the group rather than a rapper. Their lyrics are noted for bringing a "cartoonish" approach to violence by Peter Shapiro and Allmusic. Production The sound and groove of their music, mostly produced by DJ Muggs, has spooky sounds and a stoned aesthetic; with its bass-heavy rhythms and odd sample loops ("Insane in the Brain" has a blues guitar pitched looped in its chorus), it carries a psychedelic value, which is lessened in their rock-oriented albums. For using rock/metal instrumentation the band is sometimes classified as a rap rock/metal rap group. The double album Skull & Bones consists of a pure rap disc (Skull) and a separate rock disc (Bones). In the live album Live at The Fillmore, some of the old classics were played in a rock/metal version, with Eric Bobo playing the drums and Sen Dog's band SX-10 as the other instrumentalists. 2010's Rise Up was the most radically different album in regards to production. DJ Muggs had produced the majority of each prior Cypress Hill album, but he only appeared on Rise Up twice. The remaining songs were handled by various other guests. 2018's Elephants on Acid marked the return of DJ Muggs, and the album featured a more psychedelic and hip-hop approach.

Californium is a radioactive chemical element with the symbol Cf and atomic number 98. The element was first synthesized in 1950 at the Lawrence Berkeley National Laboratory (then the University of California Radiation Laboratory), by bombarding curium with alpha particles (helium-4 ions). It is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the naked eye (after einsteinium). The element was named after the university and the U.S. state of California. Two crystalline forms exist for californium under normal pressure: one above and one below . A third form exists at high pressure. Californium slowly tarnishes in air at room temperature. Californium compounds are dominated by the +3 oxidation state. The most stable of californium's twenty known isotopes is californium-251, which has a half-life of 898 years. This short half-life means the element is not found in significant quantities in the Earth's crust. Californium-252, with a half-life of about 2.645 years, is the most common isotope used and is produced at the Oak Ridge National Laboratory in the United States and the Research Institute of Atomic Reactors in Russia. Californium is one of the few transuranium elements that have practical applications. Most of these applications exploit the property of certain isotopes of californium to emit neutrons. For example, californium can be used to help start up nuclear reactors, and it is employed as a source of neutrons when studying materials using neutron diffraction and neutron spectroscopy. Californium can also be used in nuclear synthesis of higher mass elements; oganesson (element 118) was synthesized by bombarding californium-249 atoms with calcium-48 ions. Users of californium must take into account radiological concerns and the element's ability to disrupt the formation of red blood cells by bioaccumulating in skeletal tissue. Characteristics Physical properties Californium is a silvery-white actinide metal with a melting point of and an estimated boiling point of . The pure metal is malleable and is easily cut with a razor blade. Californium metal starts to vaporize above when exposed to a vacuum. Below californium metal is either ferromagnetic or ferrimagnetic (it acts like a magnet), between 48 and 66 K it is antiferromagnetic (an intermediate state), and above it is paramagnetic (external magnetic fields can make it magnetic). It forms alloys with lanthanide metals but little is known about the resulting materials. The element has two crystalline forms at standard atmospheric pressure: a double-hexagonal close-packed form dubbed alpha (α) and a face-centered cubic form designated beta (β). The α form exists below 600–800 °C with a density of 15.10 g/cm3 and the β form exists above 600–800 °C with a density of 8.74 g/cm3. At 48 GPa of pressure the β form changes into an orthorhombic crystal system due to delocalization of the atom's 5f electrons, which frees them to bond. The bulk modulus of a material is a measure of its resistance to uniform pressure. Californium's bulk modulus is , which is similar to trivalent lanthanide metals but smaller than more familiar metals, such as aluminium (70 GPa). Chemical properties and compounds Californium exhibits oxidation states of 4, 3, or 2. It typically forms eight or nine bonds to surrounding atoms or ions. Its chemical properties are predicted to be similar to other primarily 3+ valence actinide elements and the element dysprosium, which is the lanthanide above californium in the periodic table. Compounds in the +4 oxidation state are strong oxidizing agents and those in the +2 state are strong reducing agents. The element slowly tarnishes in air at room temperature, with the rate increasing when moisture is added. Californium reacts when heated with hydrogen, nitrogen, or a chalcogen (oxygen family element); reactions with dry hydrogen and aqueous mineral acids are rapid. Californium is only water-soluble as the californium(III) cation. Attempts to reduce or oxidize the +3 ion in solution have failed. The element forms a water-soluble chloride, nitrate, perchlorate, and sulfate and is precipitated as a fluoride, oxalate, or hydroxide. Californium is the heaviest actinide to exhibit covalent properties, as is observed in the californium borate. Isotopes Twenty radioisotopes of californium have been characterized, the most stable being californium-251 with a half-life of 898 years, californium-249 with a half-life of 351 years, californium-250 with a half-life of 13.08 years, and californium-252 with a half-life of 2.645 years. All the remaining isotopes have half-lives shorter than a year, and the majority of these have half-lives shorter than 20 minutes. The isotopes of californium range in mass number from 237 to 256. Californium-249 is formed from the beta decay of berkelium-249, and most other californium isotopes are made by subjecting berkelium to intense neutron radiation in a nuclear reactor. Although californium-251 has the longest half-life, its production yield is only 10% due to its tendency to collect neutrons (high neutron capture) and its tendency to interact with other particles (high neutron cross section). Californium-252 is a very strong neutron emitter, which makes it extremely radioactive and harmful. Californium-252 undergoes alpha decay 96.9% of the time to form curium-248 while the remaining 3.1% of decays are spontaneous fission. One microgram (μg) of californium-252 emits 2.3 million neutrons per second, an average of 3.7 neutrons per spontaneous fission. Most of the other isotopes of californium decay to isotopes of curium (atomic number 96) via alpha decay. History Californium was first synthesized at the University of California Radiation Laboratory in Berkeley, by the physics researchers Stanley Gerald Thompson, Kenneth Street Jr., Albert Ghiorso, and Glenn T. Seaborg on or around February 9, 1950. It was the sixth transuranium element to be discovered; the team announced its discovery on March 17, 1950. To produce californium, a microgram-sized target of curium-242 () was bombarded with 35 MeV alpha particles () in the cyclotron at Berkeley, which produced californium-245 () plus one free neutron (). + → + To identify and separate out the element, ion exchange and adsorsion methods were undertaken. Only about 5,000 atoms of californium were produced in this experiment, and these atoms had a half-life of 44 minutes. The discoverers named the new element after the university and the state. This was a break from the convention used for elements 95 to 97, which drew inspiration from how the elements directly above them in the periodic table were named. However, the element directly above element 98 in the periodic table, dysprosium, has a name that simply means "hard to get at", so the researchers decided to set aside the informal naming convention. They added that "the best we can do is to point out [that] ... searchers a century ago found it difficult to get to California". Weighable quantities of californium were first produced by the irradiation of plutonium targets at the Materials Testing Reactor at the National Reactor Testing Station in eastern Idaho; and these findings were reported in 1954. The high spontaneous fission rate of californium-252 was observed in these samples. The first experiment with californium in concentrated form occurred in 1958. The isotopes californium-249 to californium-252 were isolated that same year from a sample of plutonium-239 that had been irradiated with neutrons in a nuclear reactor for five years. Two years later, in 1960, Burris Cunningham and James Wallman of the Lawrence Radiation Laboratory of the University of California created the first californium compounds—californium trichloride, californium(III) oxychloride, and californium oxide—by treating californium with steam and hydrochloric acid. The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, started producing small batches of californium in the 1960s. By 1995, the HFIR nominally produced of californium annually. Plutonium supplied by the United Kingdom to the United States under the 1958 US–UK Mutual Defence Agreement was used for californium production. The Atomic Energy Commission sold californium-252 to industrial and academic customers in the early 1970s for $10 per microgram, and an average of of californium-252 were shipped each year from 1970 to 1990. Californium metal was first prepared in 1974 by Haire and Baybarz, who reduced californium(III) oxide with lanthanum metal to obtain microgram amounts of sub-micrometer thick films. Occurrence Traces of californium can be found near facilities that use the element in mineral prospecting and in medical treatments. The element is fairly insoluble in water, but it adheres well to ordinary soil; and concentrations of it in the soil can be 500 times higher than in the water surrounding the soil particles. Nuclear fallout from atmospheric nuclear weapons testing prior to 1980 contributed a small amount of californium to the environment. Californium isotopes with mass numbers 249, 252, 253, and 254 have been observed in the radioactive dust collected from the air after a nuclear explosion. Californium is not a major radionuclide at United States Department of Energy legacy sites since it was not produced in large quantities. Californium was once believed to be produced in supernovas, as their decay matches the 60-day half-life of 254Cf. However, subsequent studies failed to demonstrate any californium spectra, and supernova light curves are now thought to follow the decay of nickel-56. The transuranium elements from americium to fermium, including californium, occurred naturally in the natural nuclear fission reactor at Oklo, but no longer do so. Spectral lines of californium, along with those of several other non-primordial elements, were detected in Przybylski's Star in 2008. Production Californium is produced in nuclear reactors and particle accelerators. Californium-250 is made by bombarding berkelium-249 () with neutrons, forming berkelium-250 () via neutron capture (n,γ) which, in turn, quickly beta decays (β−) to californium-250 () in the following reaction: (n,γ) → + β− Bombardment of californium-250 with neutrons produces californium-251 and californium-252. Prolonged irradiation of americium, curium, and plutonium with neutrons produces milligram amounts of californium-252 and microgram amounts of californium-249. As of 2006, curium isotopes 244 to 248 are irradiated by neutrons in special reactors to produce primarily californium-252 with lesser amounts of isotopes 249 to 255. Microgram quantities of californium-252 are available for commercial use through the U.S. Nuclear Regulatory Commission. Only two sites produce californium-252: the Oak Ridge National Laboratory in the United States, and the Research Institute of Atomic Reactors in Dimitrovgrad, Russia. As of 2003, the two sites produce 0.25 grams and 0.025 grams of californium-252 per year, respectively. Three californium isotopes with significant half-lives are produced, requiring a total of 15 neutron captures by uranium-238 without nuclear fission or alpha decay occurring during the process. Californium-253 is at the end of a production chain that starts with uranium-238, includes several isotopes of plutonium, americium, curium, berkelium, and the californium isotopes 249 to 253 (see diagram). Applications Californium-252 has a number of specialized applications as a strong neutron emitter, and each microgram of fresh californium produces 139 million neutrons per minute. This property makes californium useful as a startup neutron source for some nuclear reactors and as a portable (non-reactor based) neutron source for neutron activation analysis to detect trace amounts of elements in samples. Neutrons from californium are employed as a treatment of certain cervical and brain cancers where other radiation therapy is ineffective. It has been used in educational applications since 1969 when the Georgia Institute of Technology received a loan of 119 μg of californium-252 from the Savannah River Site. It is also used with online elemental coal analyzers and bulk material analyzers in the coal and cement industries. Neutron penetration into materials makes californium useful in detection instruments such as fuel rod scanners; neutron radiography of aircraft and weapons components to detect corrosion, bad welds, cracks and trapped moisture; and in portable metal detectors. Neutron moisture gauges use californium-252 to find water and petroleum layers in oil wells, as a portable neutron source for gold and silver prospecting for on-the-spot analysis, and to detect ground water movement. The major uses of californium-252 in 1982 were, in order of use, reactor start-up (48.3%), fuel rod scanning (25.3%), and activation analysis (19.4%). By 1994, most californium-252 was used in neutron radiography (77.4%), with fuel rod scanning (12.1%) and reactor start-up (6.9%) as important but distant secondary uses. In 2021, fast neutrons from a californium-252 source were used for wireless data transmission. Californium-251 has a very small calculated critical mass of about , high lethality, and a relatively short period of toxic environmental irradiation. The low critical mass of californium led to some exaggerated claims about possible uses for the element. In October 2006, researchers announced that three atoms of oganesson (element 118) had been identified at the Joint Institute for Nuclear Research in Dubna, Russia, as the product of bombardment of californium-249 with calcium-48, making it the heaviest element ever synthesized. The target for this experiment contained about 10 mg of californium-249 deposited on a titanium foil of 32 cm2 area. Californium has also been used to produce other transuranium elements; for example, element 103 (later named lawrencium) was first synthesized in 1961 by bombarding californium with boron nuclei. Precautions Californium that bioaccumulates in skeletal tissue releases radiation that disrupts the body's ability to form red blood cells. The element plays no natural biological role in any organism due to its intense radioactivity and low concentration in the environment. Californium can enter the body from ingesting contaminated food or drinks or by breathing air with suspended particles of the element. Once in the body, only 0.05% of the californium will reach the bloodstream. About 65% of that californium will be deposited in the skeleton, 25% in the liver, and the rest in other organs, or excreted, mainly in urine. Half of the californium deposited in the skeleton and liver are gone in 50 and 20 years, respectively. Californium in the skeleton adheres to bone surfaces before slowly migrating throughout the bone. The element is most dangerous if taken into the body. In addition, californium-249 and californium-251 can cause tissue damage externally, through gamma ray emission. Ionizing radiation emitted by californium on bone and in the liver can cause cancer.

A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to respond normally to painful stimuli, light, or sound, lacks a normal wake-sleep cycle and does not initiate voluntary actions. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, speak or move. Comas can be derived by natural causes, or can be medically induced. Clinically, a coma can be defined as the inability consistently to follow a one-step command. It can also be defined as a score of ≤ 8 on the Glasgow Coma Scale (GCS) lasting ≥ 6 hours. For a patient to maintain consciousness, the components of wakefulness and awareness must be maintained. Wakefulness describes the quantitative degree of consciousness, whereas awareness relates to the qualitative aspects of the functions mediated by the cortex, including cognitive abilities such as attention, sensory perception, explicit memory, language, the execution of tasks, temporal and spatial orientation and reality judgment. From a neurological perspective, consciousness is maintained by the activation of the cerebral cortex—the gray matter that forms the outer layer of the brain—and by the reticular activating system (RAS), a structure located within the brainstem. Etymology The term 'coma', from the Greek koma, meaning deep sleep, had already been used in the Hippocratic corpus (Epidemica) and later by Galen (second century AD). Subsequently, it was hardly used in the known literature up to the middle of the 17th century. The term is found again in Thomas Willis' (1621–1675) influential De anima brutorum (1672), where lethargy (pathological sleep), 'coma' (heavy sleeping), carus (deprivation of the senses) and apoplexy (into which carus could turn and which he localized in the white matter) are mentioned. The term carus is also derived from Greek, where it can be found in the roots of several words meaning soporific or sleepy. It can still be found in the root of the term 'carotid'. Thomas Sydenham (1624–89) mentioned the term 'coma' in several cases of fever (Sydenham, 1685). Signs and symptoms General symptoms of a person in a comatose state are: Inability to voluntarily open the eyes A non-existent sleep-wake cycle Lack of response to physical (painful) or verbal stimuli Depressed brainstem reflexes, such as pupils not responding to light Irregular breathing Scores between 3 and 8 on the Glasgow Coma Scale Causes Many types of problems can cause a coma. Forty percent of comatose states result from drug poisoning. Certain drug use under certain conditions can damage or weaken the synaptic functioning in the ascending reticular activating system (ARAS) and keep the system from properly functioning to arouse the brain. Secondary effects of drugs, which include abnormal heart rate and blood pressure, as well as abnormal breathing and sweating, may also indirectly harm the functioning of the ARAS and lead to a coma. Given that drug poisoning is the cause for a large portion of patients in a coma, hospitals first test all comatose patients by observing pupil size and eye movement, through the vestibular-ocular reflex. (See Diagnosis below.) The second most common cause of coma, which makes up about 25% of cases, is lack of oxygen, generally resulting from cardiac arrest. The Central Nervous System (CNS) requires a great deal of oxygen for its neurons. Oxygen deprivation in the brain, also known as hypoxia, causes sodium and calcium from outside of the neurons to decrease and intracellular calcium to increase, which harms neuron communication. Lack of oxygen in the brain also causes ATP exhaustion and cellular breakdown from cytoskeleton damage and nitric oxide production. Twenty percent of comatose states result from the side effects of a stroke. During a stroke, blood flow to part of the brain is restricted or blocked. An ischemic stroke, brain hemorrhage, or tumor may cause restriction of blood flow. Lack of blood to cells in the brain prevents oxygen from getting to the neurons, and consequently causes cells to become disrupted and die. As brain cells die, brain tissue continues to deteriorate, which may affect the functioning of the ARAS. The remaining 15% of comatose cases result from trauma, excessive blood loss, malnutrition, hypothermia, hyperthermia, abnormal glucose levels, and many other biological disorders. Furthermore, studies show that 1 out of 8 patients with traumatic brain injury experience a comatose state. Pathophysiology Injury to either or both of the cerebral cortex or the reticular activating system (RAS) is sufficient to cause a person to enter coma. The cerebral cortex is the outer layer of neural tissue of the cerebrum of the brain. The cerebral cortex is composed of gray matter which consists of the nuclei of neurons, whereas the inner portion of the cerebrum is composed of white matter and is composed of the axons of neuron. White matter is responsible for perception, relay of the sensory input via the thalamic pathway, and many other neurological functions, including complex thinking. The RAS, on the other hand, is a more primitive structure in the brainstem which includes the reticular formation (RF). The RAS has two tracts, the ascending and descending tract. The ascending track, or ascending reticular activating system (ARAS), is made up of a system of acetylcholine-producing neurons, and works to arouse and wake up the brain. Arousal of the brain begins from the RF, through the thalamus, and then finally to the cerebral cortex. Any impairment in ARAS functioning, a neuronal dysfunction, along the arousal pathway stated directly above, prevents the body from being aware of its surroundings. Without the arousal and consciousness centers, the body cannot awaken, remaining in a comatose state. The severity and mode of onset of coma depends on the underlying cause. There are two main subdivisions of a coma: structural and diffuse neuronal. A structural cause, for example, is brought upon by a mechanical force that brings about cellular damage, such as physical pressure or a blockage in neural transmission. While a diffuse cause is limited to aberrations of cellular function, that fall under a metabolic or toxic subgroup. Toxin-induced comas are caused by extrinsic substances, whereas metabolic-induced comas are caused by intrinsic processes, such as body thermoregulation or ionic imbalances(e.g. sodium). For instance, severe hypoglycemia (low blood sugar) or hypercapnia (increased carbon dioxide levels in the blood) are examples of a metabolic diffuse neuronal dysfunction. Hypoglycemia or hypercapnia initially cause mild agitation and confusion, but progress to obtundation, stupor, and finally, complete unconsciousness. In contrast, coma resulting from a severe traumatic brain injury or subarachnoid hemorrhage can be instantaneous. The mode of onset may therefore be indicative of the underlying cause. Structural and diffuse causes of coma are not isolated from one another, as one can lead to the other in some situations. For instance, coma induced by a diffuse metabolic process, such as hypoglycemia, can result in a structural coma if it is not resolved. Another example is if cerebral edema, a diffuse dysfunction, leads to ischemia of the brainstem, a structural issue, due to the blockage of the circulation in the brain. Diagnosis Although diagnosis of coma is simple, investigating the underlying cause of onset can be rather challenging. As such, after gaining stabilization of the patient's airways, breathing and circulation (the basic ABCs) various diagnostic tests, such as physical examinations and imaging tools (CT scan, MRI, etc.) are employed to access the underlying cause of the coma. When an unconscious person enters a hospital, the hospital utilizes a series of diagnostic steps to identify the cause of unconsciousness. According to Young, the following steps should be taken when dealing with a patient possibly in a coma: Perform a general examination and medical history check Make sure the patient is in an actual comatose state and is not in a locked-in state or experiencing psychogenic unresponsiveness. Patients with locked-in syndrome present with voluntary movement their eyes, whereas patients suffering from psychogenic comas, demonstrate active resistance to passive opening of the eyelids, with the eyelids closing abruptly and completely when the lifted upper eyelid is released (rather than slowly, asymmetrically and incompletely as seen in comas due to organic causes). Find the site of the brain that may be causing coma (i.e., brainstem, back of brain...) and assess the severity of the coma with the Glasgow Coma Scale Take blood work to see if drugs were involved or if it was a result of hypoventilation/hyperventilation Check for levels of “serum glucose, calcium, sodium, potassium, magnesium, phosphate, urea, and creatinine” Perform brain scans to observe any abnormal brain functioning using either CT or MRI scans Continue to monitor brain waves and identify seizures of patient using EEGs Initial evaluation In the initial assessment of coma, it is common to gauge the level of consciousness on the AVPU (alert, vocal stimuli, painful stimuli, unresponsive) scale by spontaneously exhibiting actions and, assessing the patient's response to vocal and painful stimuli. More elaborate scales, such as the Glasgow Coma Scale, quantify an individual's reactions such as eye opening, movement and verbal response in order to indicate their extent of brain injury. The patient's score can vary from a score of 3 (indicating severe brain injury and death) to 15 (indicating mild or no brain injury). In those with deep unconsciousness, there is a risk of asphyxiation as the control over the muscles in the face and throat is diminished. As a result, those presenting to a hospital with coma are typically assessed for this risk ("airway management"). If the risk of asphyxiation is deemed high, doctors may use various devices (such as an oropharyngeal airway, nasopharyngeal airway or endotracheal tube) to safeguard the airway. Imaging and testing Imaging basically encompasses computed tomography (CAT or CT) scan of the brain, or MRI for example, and is performed to identify specific causes of the coma, such as hemorrhage in the brain or herniation of the brain structures. Special tests such as an EEG can also show a lot about the activity level of the cortex such as semantic processing, presence of seizures, and are important available tools not only for the assessment of the cortical activity but also for predicting the likelihood of the patient's awakening. The autonomous responses such as the skin conductance response may also provide further insight on the patient's emotional processing. In the treatment of traumatic brain injury (TBI), there are 4 examination methods that have proved useful: skull x-ray, angiography, computed tomography (CT), and magnetic resonance imaging (MRI). The skull x-ray can detect linear fractures, impression fractures (expression fractures) and burst fractures. Angiography is used on rare occasions for TBIs i.e. when there is suspicion of an aneurysm, carotid sinus fistula, traumatic vascular occlusion, and vascular dissection. A CT can detect changes in density between the brain tissue and hemorrhages like subdural and intracerebral hemorrhages. MRIs are not the first choice in emergencies because of the long scanning times and because fractures cannot be detected as well as CT. MRIs are used for the imaging of soft tissues and lesions in the posterior fossa which cannot be found with the use of CT. Body movements Assessment of the brainstem and cortical function through special reflex tests such as the oculocephalic reflex test (doll's eyes test), oculovestibular reflex test (cold caloric test), corneal reflex, and the gag reflex. Reflexes are a good indicator of what cranial nerves are still intact and functioning and is an important part of the physical exam. Due to the unconscious status of the patient, only a limited number of the nerves can be assessed. These include the cranial nerves number 2 (CN II), number 3 (CN III), number 5 (CN V), number 7 (CN VII), and cranial nerves 9 and 10 (CN IX, CN X). Assessment of posture and physique is the next step. It involves general observation about the patient's positioning. There are often two stereotypical postures seen in comatose patients. Decorticate posturing is a stereotypical posturing in which the patient has arms flexed at the elbow, and arms adducted toward the body, with both legs extended. Decerebrate posturing is a stereotypical posturing in which the legs are similarly extended (stretched), but the arms are also stretched (extended at the elbow). The posturing is critical since it indicates where the damage is in the central nervous system. A decorticate posturing indicates a lesion (a point of damage) at or above the red nucleus, whereas a decerebrate posturing indicates a lesion at or below the red nucleus. In other words, a decorticate lesion is closer to the cortex, as opposed to a decerebrate posturing which indicates that the lesion is closer to the brainstem. Pupil size Pupil assessment is often a critical portion of a comatose examination, as it can give information as to the cause of the coma; the following table is a technical, medical guideline for common pupil findings and their possible interpretations: Severity A coma can be classified as (1) supratentorial (above Tentorium cerebelli), (2) infratentorial (below Tentorium cerebelli), (3) metabolic or (4) diffused. This classification is merely dependent on the position of the original damage that caused the coma, and does not correlate with severity or the prognosis. The severity of coma impairment however is categorized into several levels. Patients may or may not progress through these levels. In the first level, the brain responsiveness lessens, normal reflexes are lost, the patient no longer responds to pain and cannot hear. The Rancho Los Amigos Scale is a complex scale that has eight separate levels, and is often used in the first few weeks or months of coma while the patient is under closer observation, and when shifts between levels are more frequent. Treatment Treatment for people in a coma will depend on the severity and cause of the comatose state. Upon admittance to an emergency department, coma patients will usually be placed in an Intensive Care Unit (ICU) immediately, where maintenance of the patient's respiration and circulation become a first priority. Stability of their respiration and circulation is sustained through the use of intubation, ventilation, administration of intravenous fluids or blood and other supportive care as needed. Continued care Once a patient is stable and no longer in immediate danger, there may be a shift of priority from stabilizing the patient to maintaining the state of their physical wellbeing. Moving patients every 2–3 hours by turning them side to side is crucial to avoiding bed sores as a result of being confined to a bed. Moving patients through the use of physical therapy also aids in preventing atelectasis, contractures or other orthopedic deformities which would interfere with a coma patient's recovery. Pneumonia is also common in coma patients due to their inability to swallow which can then lead to aspiration. A coma patient's lack of a gag reflex and use of a feeding tube can result in food, drink or other solid organic matter being lodged within their lower respiratory tract (from the trachea to the lungs). This trapping of matter in their lower respiratory tract can ultimately lead to infection, resulting in aspiration pneumonia. Coma patients may also deal with restlessness or seizures. As such, soft cloth restraints may be used to prevent them from pulling on tubes or dressings and side rails on the bed should be kept up to prevent patients from falling. Caregivers Coma has a wide variety of emotional reactions from the family members of the affected patients, as well as the primary care givers taking care of the patients. Research has shown that the severity of injury causing coma was found to have no significant impact compared to how much time has passed since the injury occurred. Common reactions, such as desperation, anger, frustration, and denial are possible. The focus of the patient care should be on creating an amicable relationship with the family members or dependents of a comatose patient as well as creating a rapport with the medical staff. Although there is heavy importance of a primary care taker, secondary care takers can play a supporting role to temporarily relieve the primary care taker's burden of tasks. Prognosis Comas can last from several days to, in particularly extreme cases, years. After this time, some patients gradually come out of the coma, some progress to a vegetative state, and others die. Some patients who have entered a vegetative state go on to regain a degree of awareness and in some cases, may remain in vegetative state for years or even decades (the longest recorded period being 42 years). Predicted chances of recovery will differ depending on which techniques were used to measure the patient's severity of neurological damage. Predictions of recovery are based on statistical rates, expressed as the level of chance the person has of recovering. Time is the best general predictor of a chance of recovery. For example, after four months of coma caused by brain damage, the chance of partial recovery is less than 15%, and the chance of full recovery is very low. The outcome for coma and vegetative state depends on the cause, location, severity and extent of neurological damage. A deeper coma alone does not necessarily mean a slimmer chance of recovery, similarly, milder comas do not ensure higher chances of recovery. The most common cause of death for a person in a vegetative state is secondary infection such as pneumonia, which can occur in patients who lie still for extended periods. Recovery People may emerge from a coma with a combination of physical, intellectual, and psychological difficulties that need special attention. It is common for coma patients to awaken in a profound state of confusion and suffer from dysarthria, the inability to articulate any speech. Recovery usually occurs gradually. In the first days, patients may only awaken for a few minutes, with increased duration of wakefulness as their recovery progresses and may eventually recover full awareness. That said, some patients may never progress beyond very basic responses. There are reports of people coming out of a coma after long periods of time. After 19 years in a minimally conscious state, Terry Wallis spontaneously began speaking and regained awareness of his surroundings. A brain-damaged man, trapped in a coma-like state for six years, was brought back to consciousness in 2003 by doctors who planted electrodes deep inside his brain. The method, called deep brain stimulation (DBS) successfully roused communication, complex movement and eating ability in the 38-year-old American man who suffered a traumatic brain injury. His injuries left him in a minimally conscious state (MCS), a condition akin to a coma but characterized by occasional, but brief, evidence of environmental and self-awareness that coma patients lack. Society and culture Research by Dr. Eelco Wijdicks on the depiction of comas in movies was published in Neurology in May 2006. Dr. Wijdicks studied 30 films (made between 1970 and 2004) that portrayed actors in prolonged comas, and he concluded that only two films accurately depicted the state of a coma victim and the agony of waiting for a patient to awaken: Reversal of Fortune (1990) and The Dreamlife of Angels (1998). The remaining 28 were criticized for portraying miraculous awakenings with no lasting side effects, unrealistic depictions of treatments and equipment required, and comatose patients remaining muscular and tanned. Bioethics A person in a coma is said to be in an unconscious state. Perspectives on personhood, identity and consciousness come into play when discussing the metaphysical and bioethical views on comas. It has been argued that unawareness should be just as ethically relevant and important as a state of awareness and that there should be metaphysical support of unawareness as a state. In the ethical discussions about disorders of consciousness (DOCs), two abilities are usually considered as central: experiencing well-being and having interests. Well-being can broadly be understood as the positive effect related to what makes life good (according to specific standards) for the individual in question. The only condition for well-being broadly considered is the ability to experience its ‘positiveness’. That said, because experiencing positiveness is a basic emotional process with phylogenetic roots, it is likely to occur at a completely unaware level and therefore, introduces the idea of an unconscious well-being. As such, the ability of having interests, is crucial for describing two abilities which those with comas are deficient in. Having an interest in a certain domain can be understood as having a stake in something that can affect what makes our life good in that domain. An interest is what directly and immediately improves life from a certain point of view or within a particular domain, or greatly increases the likelihood of life improvement enabling the subject to realize some good. That said, sensitivity to reward signals is a fundamental element in the learning process, both consciously and unconsciously. Moreover, the unconscious brain is able to interact with its surroundings in a meaningful way and to produce meaningful information processing of stimuli coming from the external environment, including other people. According to Hawkins, "1. A life is good if the subject is able to value, or more basically if the subject is able to care. Importantly, Hawkins stresses that caring has no need for cognitive commitment, i.e. for high-level cognitive activities: it requires being able to distinguish something, track it for a while, recognize it over time, and have certain emotional dispositions vis-à-vis something. 2. A life is good if the subject has the capacity for relationship with others, i.e. for meaningfully interacting with other people." This suggests that unawareness may (at least partly) fulfill both conditions identified by Hawkins for life to be good for a subject, thus making the unconscious ethically relevant.

Chinese numerals are words and characters used to denote numbers in Chinese. Today, speakers of Chinese use three written numeral systems: the system of Arabic numerals used worldwide, and two indigenous systems. The more familiar indigenous system is based on Chinese characters that correspond to numerals in the spoken language. These may be shared with other languages of the Chinese cultural sphere such as Korean, Japanese, and Vietnamese. Most people and institutions in China and Taiwan primarily use the Arabic or mixed Arabic-Chinese systems for convenience, with traditional Chinese numerals used in finance, mainly for writing amounts on checks, banknotes, some ceremonial occasions, some boxes, and on commercials. The other indigenous system is the Suzhou numerals, or huama, a positional system, the only surviving form of the rod numerals. These were once used by Chinese mathematicians, and later in Chinese markets, such as those in Hong Kong before the 1990s, but have been gradually supplanted by Arabic (and also Roman) numerals. Characters used to represent numbers The Chinese character numeral system consists of the Chinese characters used by the Chinese written language to write spoken numerals. Similar to spelling-out numbers in English (e.g., "one thousand nine hundred forty-five"), it is not an independent system per se. Since it reflects spoken language, it does not use the positional system as in Arabic numerals, in the same way that spelling out numbers in English does not. Standard numbers There are characters representing the numbers zero through nine, and other characters representing larger numbers such as tens, hundreds, thousands, ten thousands and hundred millions. There are two sets of characters for Chinese numerals: one for everyday writing, known as xiǎoxiě (), and one for use in commercial, accounting or financial contexts, known as dàxiě (). The latter arose because the characters used for writing numerals are geometrically simple, so simply using those numerals cannot prevent forgeries in the same way spelling numbers out in English would. A forger could easily change the everyday characters 三十 (30) to 五千 (5000) just by adding a few strokes. That would not be possible when writing using the financial characters 參拾 (30) and 伍仟 (5000). They are also referred to as "banker's numerals", "anti-fraud numerals", or "banker's anti-fraud numerals". For the same reason, rod numerals were never used in commercial records. T denotes Traditional Chinese characters, while S denotes Simplified Chinese characters. Characters with regional usage Large numbers For numbers larger than 10,000, similarly to the long and short scales in the West, there have been four systems in ancient and modern usage. The original one, with unique names for all powers of ten up to the 14th, is ascribed to the Yellow Emperor in the 6th century book by Zhen Luan, Wujing suanshu (Arithmetic in Five Classics). In modern Chinese only the second system is used, in which the same ancient names are used, but each represents a number 10,000 (myriad, 萬 wàn) times the previous: In practice, this situation does not lead to ambiguity, with the exception of 兆 (zhào), which means 1012 according to the system in common usage throughout the Chinese communities as well as in Japan and Korea, but has also been used for 106 in recent years (especially in mainland China for megabyte). To avoid problems arising from the ambiguity, the PRC government never uses this character in official documents, but uses 万亿 (wànyì) or 太 (tài, as the translation for tera) instead. Partly due to this, combinations of 万 and 亿 are often used instead of the larger units of the traditional system as well, for example 亿亿 (yìyì) instead of 京. The ROC government in Taiwan uses 兆 (zhào) to mean 1012 in official documents. Large numbers from Buddhism Numerals beyond 載 zǎi come from Buddhist texts in Sanskrit, but are mostly found in ancient texts. Some of the following words are still being used today, but may have transferred meanings. Small numbers The following are characters used to denote small order of magnitude in Chinese historically. With the introduction of SI units, some of them have been incorporated as SI prefixes, while the rest have fallen into disuse. Small numbers from Buddhism SI prefixes In the People's Republic of China, the early translation for the SI prefixes in 1981 was different from those used today. The larger (兆, 京, 垓, 秭, 穰) and smaller Chinese numerals (微, 纖, 沙, 塵, 渺) were defined as translation for the SI prefixes as mega, giga, tera, peta, exa, micro, nano, pico, femto, atto, resulting in the creation of yet more values for each numeral. The Republic of China (Taiwan) defined 百萬 as the translation for mega and 兆 as the translation for tera. This translation is widely used in official documents, academic communities, informational industries, etc. However, the civil broadcasting industries sometimes use 兆赫 to represent "megahertz". Today, the governments of both China and Taiwan use phonetic transliterations for the SI prefixes. However, the governments have each chosen different Chinese characters for certain prefixes. The following table lists the two different standards together with the early translation. Reading and transcribing numbers Whole numbers Multiple-digit numbers are constructed using a multiplicative principle; first the digit itself (from 1 to 9), then the place (such as 10 or 100); then the next digit. In Mandarin, the multiplier (liǎng) is often used rather than (èr) for all numbers 200 and greater with the "2" numeral (although as noted earlier this varies from dialect to dialect and person to person). Use of both 兩 (liǎng) or 二 (èr) are acceptable for the number 200. When writing in the Cantonese dialect, 二 (yi6) is used to represent the "2" numeral for all numbers. In the southern Min dialect of Chaozhou (Teochew), 兩 (no6) is used to represent the "2" numeral in all numbers from 200 onwards. Thus: For the numbers 11 through 19, the leading "one" () is usually omitted. In some dialects, like Shanghainese, when there are only two significant digits in the number, the leading "one" and the trailing zeroes are omitted. Sometimes, the one before "ten" in the middle of a number, such as 213, is omitted. Thus: Notes: Nothing is ever omitted in large and more complicated numbers such as this. In certain older texts like the Protestant Bible or in poetic usage, numbers such as 114 may be written as [100] [10] [4] (). Outside of Taiwan, digits are sometimes grouped by myriads instead of thousands. Hence it is more convenient to think of numbers here as in groups of four, thus 1,234,567,890 is regrouped here as 12,3456,7890. Larger than a myriad, each number is therefore four zeroes longer than the one before it, thus 10000 × () = (). If one of the numbers is between 10 and 19, the leading "one" is omitted as per the above point. Hence (numbers in parentheses indicate that the number has been written as one number rather than expanded): In Taiwan, pure Arabic numerals are officially always and only grouped by thousands. Unofficially, they are often not grouped, particularly for numbers below 100,000. Mixed Arabic-Chinese numerals are often used in order to denote myriads. This is used both officially and unofficially, and come in a variety of styles: Interior zeroes before the unit position (as in 1002) must be spelt explicitly. The reason for this is that trailing zeroes (as in 1200) are often omitted as shorthand, so ambiguity occurs. One zero is sufficient to resolve the ambiguity. Where the zero is before a digit other than the units digit, the explicit zero is not ambiguous and is therefore optional, but preferred. Thus: Fractional values To construct a fraction, the denominator is written first, followed by , then the literary possessive particle , and lastly the numerator. This is the opposite of how fractions are read in English, which is numerator first. Each half of the fraction is written the same as a whole number. For example, to express "two thirds", the structure "three parts of-this two" is used. Mixed numbers are written with the whole-number part first, followed by , then the fractional part. Percentages are constructed similarly, using as the denominator. (The number 100 is typically expressed as , like the English "one hundred". However, for percentages, is used on its own.) Because percentages and other fractions are formulated the same, Chinese are more likely than not to express 10%, 20% etc. as "parts of 10" (or 1/10, 2/10, etc. i.e. ; shí fēnzhī yī, ; shí fēnzhī èr, etc.) rather than "parts of 100" (or 10/100, 20/100, etc. i.e. ; bǎi fēnzhī shí, ; bǎi fēnzhī èrshí, etc.) In Taiwan, the most common formation of percentages in the spoken language is the number per hundred followed by the word ; pā, a contraction of the Japanese ; pāsento, itself taken from the English "percent". Thus 25% is ; èrshíwǔ pā. Decimal numbers are constructed by first writing the whole number part, then inserting a point (), and finally the fractional part. The fractional part is expressed using only the numbers for 0 to 9, similarly to English. functions as a number and therefore requires a measure word. For example: . Ordinal numbers Ordinal numbers are formed by adding ("sequence") before the number. The Heavenly Stems are a traditional Chinese ordinal system. Negative numbers Negative numbers are formed by adding fù () before the number. Usage Chinese grammar requires the use of classifiers (measure words) when a numeral is used together with a noun to express a quantity. For example, "three people" is expressed as , "three ( particle) person", where / is a classifier. There exist many different classifiers, for use with different sets of nouns, although / is the most common, and may be used informally in place of other classifiers. Chinese uses cardinal numbers in certain situations in which English would use ordinals. For example, (literally "three story/storey") means "third floor" ("second floor" in British ). Likewise, (literally "twenty-one century") is used for "21st century". Numbers of years are commonly spoken as a sequence of digits, as in ("two zero zero one") for the year 2001. Names of months and days (in the Western system) are also expressed using numbers: ("one month") for January, etc.; and ("week one") for Monday, etc. There is only one exception: Sunday is , or informally , both literally "week day". When meaning "week", "" and "" are interchangeable. "" or "" means "day of worship". Chinese Catholics call Sunday "" , "Lord's day". Full dates are usually written in the format 2001年1月20日 for January 20, 2001 (using "year", "month", and "day") – all the numbers are read as cardinals, not ordinals, with no leading zeroes, and the year is read as a sequence of digits. For brevity the , and may be dropped to give a date composed of just numbers. For example "6-4" in Chinese is "six-four", short for "month six, day four" i.e. June Fourth, a common Chinese shorthand for the 1989 Tiananmen Square protests (because of the violence that occurred on June 4). For another example 67, in Chinese is sixty seven, short for year nineteen sixty seven, a common Chinese shorthand for the Hong Kong 1967 leftist riots. Counting rod and Suzhou numerals In the same way that Roman numerals were standard in ancient and medieval Europe for mathematics and commerce, the Chinese formerly used the rod numerals, which is a positional system. The Suzhou numerals () system is a variation of the Southern Song rod numerals. Nowadays, the huāmǎ system is only used for displaying prices in Chinese markets or on traditional handwritten invoices. Hand gestures There is a common method of using of one hand to signify the numbers one to ten. While the five digits on one hand can express the numbers one to five, six to ten have special signs that can be used in commerce or day-to-day communication. Historical use of numerals in China Most Chinese numerals of later periods were descendants of the Shang dynasty oracle numerals of the 14th century BC. The oracle bone script numerals were found on tortoise shell and animal bones. In early civilizations, the Shang were able to express any numbers, however large, with only nine symbols and a counting board. Some of the bronze script numerals such as 1, 2, 3, 4, 10, 11, 12, and 13 became part of the system of rod numerals. In this system, horizontal rod numbers are used for the tens, thousands, hundred thousands etc. It's written in Sunzi Suanjing that "one is vertical, ten is horizontal". The counting rod numerals system has place value and decimal numerals for computation, and was used widely by Chinese merchants, mathematicians and astronomers from the Han dynasty to the 16th century. In 690 AD, Empress Wǔ promulgated Zetian characters, one of which was "〇". The word is now used as a synonym for the number zero. Alexander Wylie, Christian missionary to China, in 1853 already refuted the notion that "the Chinese numbers were written in words at length", and stated that in ancient China, calculation was carried out by means of counting rods, and "the written character is evidently a rude presentation of these". After being introduced to the rod numerals, he said "Having thus obtained a simple but effective system of figures, we find the Chinese in actual use of a method of notation depending on the theory of local value [i.e. place-value], several centuries before such theory was understood in Europe, and while yet the science of numbers had scarcely dawned among the Arabs." During the Ming and Qing dynasties (after Arabic numerals were introduced into China), some Chinese mathematicians used Chinese numeral characters as positional system digits. After the Qing period, both the Chinese numeral characters and the Suzhou numerals were replaced by Arabic numerals in mathematical writings. Cultural influences Traditional Chinese numeric characters are also used in Japan and Korea and were used in Vietnam before the 20th century. In vertical text (that is, read top to bottom), using characters for numbers is the norm, while in horizontal text, Arabic numerals are most common. Chinese numeric characters are also used in much the same formal or decorative fashion that Roman numerals are in Western cultures. Chinese numerals may appear together with Arabic numbers on the same sign or document.

The Military Forces of Colombia () are the unified armed forces of the Republic of Colombia. They consist of the Colombian Army, the Colombian Navy and the Colombian Air Force. The National Police of Colombia, although technically not part of the military, is controlled and administered by the Ministry of National Defence, and national conscription also includes service in the National Police, thus making it a de facto gendarmerie and a branch of the military. The President of Colombia is the military's commander in chief, and helps formulate defense policy through the Ministry of National Defence, which is in charge of day-to-day operations. The Military Forces of Colombia have their roots in the Army of the Commoners (), which was formed on 7 August 1819 – before the establishment of the present day Colombia – to meet the demands of the Revolutionary War against the Spanish Empire. After their triumph in the war, the Army of the Commoners disbanded, and the Congress of Angostura created the Gran Colombian Army to replace it, thus establishing the first military service branch of the country. The Colombian military was operationally involved in World War II and was the only Latin American country to send troops to the Korean War. Ever since the advent of the Colombian Conflict, the Colombian military has been involved in combat, pacification, counter-insurgency, and drug interdiction operations all over the country's national territory. Recently it has participated in counter-piracy efforts in the Horn of Africa under Operation Ocean Shield and Operation Atlanta. The military of Colombia is the third largest in the Western Hemisphere in terms of active personnel and has the fourth largest expenditure in the Americas, behind the United States Armed Forces, the Canadian Armed Forces and the Brazilian Armed Forces respectively. Services The Colombian Constitution includes two overlapping definitions of what could be defined as 'armed forces' in English: The Public Force (): Includes the Military Forces proper and the National Police (Title VII, chapter VII, Art. 216) The Military Forces (): Includes only the 3 major military service branches: Army, Navy and Air Force (Title VII, chapter VII, Art. 217) This is a subtle yet important distinction, both in terms of emphasizing the civil nature of the National Police, but also adapting the national police to function as a paramilitary force which can perform military duties as a result of the Colombian Conflict. This has led to some of the most important police units adopting military training and conducting special operations alongside the Colombian Army, Air Force, and Navy. Therefore, the functions of the Colombian Police in practical terms are similar to those of a gendarmerie, like the Spanish Civil Guard and the Carabineros de Chile, which maintain military ranks for all police personnel. Personnel The Colombian armed forces consist of: Military Forces: Colombian Army Colombian Navy – and attached services Marines and Colombian Coast Guard Colombian Air Force And, National Police of Colombia Public Force strength as of April 2014.

By 2008 this figure had risen to 4.8%, ranking it 14th in the world. The armed forces number about 250,000 uniformed personnel: 145,000 military and 105,000 police. These figures do not include assistance personnel such as cooks, medics, mechanics, and so on. This makes the Colombian military one of the largest and most well-equipped in Latin America. Many Colombian military personnel have received military training assistance directly in Colombia and also in the United States. The United States has provided equipment and financing to the Colombian military and police through the military assistance program, foreign military sales, and the international narcotics control program, all currently united under the auspices of Plan Colombia.

A cultural movement is a change in the way a number of different disciplines approach their work. This embodies all art forms, the sciences, and philosophies. Historically, different nations or regions of the world have gone through their own independent sequence of movements in culture, but as world communications have accelerated this geographical distinction has become less distinct. When cultural movements go through revolutions from one to the next, genres tend to get attacked and mixed up, and often new genres are generated and old ones fade. These changes are often reactions against the prior cultural form, which typically has grown stale and repetitive. An obsession emerges among the mainstream with the new movement, and the old one falls into neglect – sometimes it dies out entirely, but often it chugs along favored in a few disciplines and occasionally making reappearances (sometimes prefixed with "neo-"). There is continual argument over the precise definition of each of these periods, and one historian might group them differently, or choose different names or descriptions. As well, even though in many cases the popular change from one to the next can be swift and sudden, the beginning and end of movements are somewhat subjective, as the movements did not spring fresh into existence out of the blue and did not come to an abrupt end and lose total support, as would be suggested by a date range. Thus use of the term "period" is somewhat deceptive. "Period" also suggests a linearity of development, whereas it has not been uncommon for two or more distinctive cultural approaches to be active at the same time. Historians will be able to find distinctive traces of a cultural movement before its accepted beginning, and there will always be new creations in old forms. So it can be more useful to think in terms of broad "movements" that have rough beginnings and endings. Yet for historical perspective, some rough date ranges will be provided for each to indicate the "height" or accepted time span of the movement. This current article covers western, notably European and American cultural movements. They have, however, been paralleled by cultural movements in the Orient and elsewhere. In the late 20th and early 21st century in Thailand, for example, there has been a cultural shift away from western social and political values more toward Japanese and Chinese. As well, That culture has reinvigorated monarchical concepts to accommodate state shifts away from western ideology regarding democracy and monarchies. Cultural movements Graeco-Roman The Greek culture marked a departure from the other Mediterranean cultures that preceded and surrounded it. The Romans adopted Greek and other styles, and spread the result throughout Europe and the Middle East. Together, Greek and Roman thought in philosophy, religion, science, history, and all forms of thought can be viewed as a central underpinning of Western culture, and is therefore termed the "Classical period" by some. Others might divide it into the Hellenistic period and the Roman period, or might choose other finer divisions. See: Classical architecture — Classical sculpture — Greek architecture — Hellenistic architecture — Ionic — Doric — Corinthian — Stoicism — Cynicism — Epicurean — Roman architecture — Early Christian — Neoplatonism Romanesque (11th century & 12th centuries) A style (esp. architectural) similar in form and materials to Roman styles. Romanesque seems to be the first pan-European style since Roman Imperial Architecture and examples are found in every part of the continent. See: Romanesque architecture — Ottonian Art Gothic (mid 12th century until mid 15th century) See: Gothic architecture — Gregorian chant — Neoplatonism Nominalism Rejects Platonic realism as a requirement for thinking and speaking in general terms. Humanism (16th century) Renaissance The use of light, shadow, and perspective to more accurately represent life. Because of how fundamentally these ideas were felt to alter so much of life, some have referred to it as the "Golden Age". In reality it was less an "Age" and more of a movement in popular philosophy, science, and thought that spread over Europe (and probably other parts of the world), over time, and affected different aspects of culture at different points in time. Very roughly, the following periods can be taken as indicative of place/time foci of the Renaissance: Italian Renaissance 1450–1550. Spanish Renaissance 1550–1587. English Renaissance 1588–1629. Protestant Reformation The Protestant Reformation, often referred to simply as the Reformation, was a schism from the Roman Catholic Church initiated by Martin Luther, John Calvin, Huldrych Zwingli and other early Protestant Reformers in the 16th century Europe. Mannerism Anti-classicist movement that sought to emphasize the feeling of the artist himself. See: Mannerism/Art Baroque Emphasizes power and authority, characterized by intricate detail and without the "disturbing angst" of Mannerism. Essentially is exaggerated Classicism to promote and glorify the Church and State. Occupied with notions of infinity. See: Baroque art — Baroque music Rococo Neoclassical (17th–19th centuries) Severe, unemotional movement recalling Roman and Greek ("classical") style, reacting against the overbred Rococo style and the emotional Baroque style. It stimulated revival of classical thinking, and had especially profound effects on science and politics. Also had a direct influence on Academic Art in the 19th century. Beginning in the early 17th century with Cartesian thought (see René Descartes), this movement provided philosophical frameworks for the natural sciences, sought to determine the principles of knowledge by rejecting all things previously believed to be known about the world. In Renaissance Classicism attempts are made to recreate the classic art forms — tragedy, comedy, and farce. See also: Weimar Classicism Age of Enlightenment (1688–1789): Reason (rationalism) seen as the ideal. Romanticism (1770–1830) Began in Germany and spread to England and France as a reaction against Neoclassicism and against the Age of Enlightenment.. The notion of "folk genius", or an inborn and intuitive ability to do magnificent things, is a core principle of the Romantic movement. Nostalgia for the primitive past in preference to the scientifically minded present. Romantic heroes, exemplified by Napoleon, are popular. Fascination with the past leads to a resurrection of interest in the Gothic period. It did not really replace the Neoclassical movement so much as provide a counterbalance; many artists sought to join both styles in their works. See: Symbolism Realism (1830–1905) Ushered in by the Industrial Revolution and growing Nationalism in the world. Began in France. Attempts to portray the speech and mannerisms of everyday people in everyday life. Tends to focus on middle class social and domestic problems. Plays by Ibsen are an example. Naturalism evolved from Realism, following it briefly in art and more enduringly in theatre, film, and literature. Impressionism, based on 'scientific' knowledge and discoveries concerns observing nature and reality objectively. See: Post-impressionism — Neo-impressionism — Pointillism — Pre-Raphaelite Art Nouveau (1880–1905) Decorative, symbolic art See: Transcendentalism Modernism (1880–1965) Also known as the Avant-garde movement. Originating in the 19th century with Symbolism, the Modernist movement composed itself of a wide range of 'isms' that ran in contrast to Realism and that sought out the underlying fundamentals of art and philosophy. The Jazz age and Hollywood emerge and have their hey-days.

In formal language theory, computer science and linguistics, the Chomsky hierarchy (also referred to as the Chomsky–Schützenberger hierarchy) is a containment hierarchy of classes of formal grammars. This hierarchy of grammars was described by Noam Chomsky in 1956. It is also named after Marcel-Paul Schützenberger, who played a crucial role in the development of the theory of formal languages. Formal grammars A formal grammar of this type consists of a finite set of production rules (left-hand side → right-hand side), where each side consists of a finite sequence of the following symbols: a finite set of nonterminal symbols (indicating that some production rule can yet be applied) a finite set of terminal symbols (indicating that no production rule can be applied) a start symbol (a distinguished nonterminal symbol) A formal grammar provides an axiom schema for (or generates) a formal language, which is a (usually infinite) set of finite-length sequences of symbols that may be constructed by applying production rules to another sequence of symbols (which initially contains just the start symbol). A rule may be applied by replacing an occurrence of the symbols on its left-hand side with those that appear on its right-hand side. A sequence of rule applications is called a derivation. Such a grammar defines the formal language: all words consisting solely of terminal symbols which can be reached by a derivation from the start symbol. Nonterminals are often represented by uppercase letters, terminals by lowercase letters, and the start symbol by . For example, the grammar with terminals , nonterminals , production rules → → (where is the empty string) → → and start symbol , defines the language of all words of the form (i.e. copies of followed by copies of ). The following is a simpler grammar that defines the same language: Terminals , Nonterminals , Start symbol , Production rules → → As another example, a grammar for a toy subset of the English language is given by: terminals nonterminals production rules → → → → → → → → → → → and start symbol . An example derivation is → → → → → → → → great → great linguists → great linguists generate → great linguists generate great → great linguists generate great green → great linguists generate great green ideas. Other sequences that can be derived from this grammar are: "ideas hate great linguists", and "ideas generate". While these sentences are nonsensical, they are syntactically correct. A syntactically incorrect sentence (e.g. "ideas ideas great hate") cannot be derived from this grammar. See "Colorless green ideas sleep furiously" for a similar example given by Chomsky in 1957; see Phrase structure grammar and Phrase structure rules for more natural language examples and the problems of formal grammar in that area. The hierarchy The following table summarizes each of Chomsky's four types of grammars, the class of language it generates, the type of automaton that recognizes it, and the form its rules must have. Note that the set of grammars corresponding to recursive languages is not a member of this hierarchy; these would be properly between Type-0 and Type-1. Every regular language is context-free, every context-free language is context-sensitive, every context-sensitive language is recursive and every recursive language is recursively enumerable. These are all proper inclusions, meaning that there exist recursively enumerable languages that are not context-sensitive, context-sensitive languages that are not context-free and context-free languages that are not regular. Type-0 grammars Type-0 grammars include all formal grammars. They generate exactly all languages that can be recognized by a Turing machine. These languages are also known as the recursively enumerable or Turing-recognizable languages. Note that this is different from the recursive languages, which can be decided by an always-halting Turing machine. Type-1 grammars Type-1 grammars generate context-sensitive languages. These grammars have rules of the form with a nonterminal and , and strings of terminals and/or nonterminals. The strings and may be empty, but must be nonempty. The rule is allowed if does not appear on the right side of any rule. The languages described by these grammars are exactly all languages that can be recognized by a linear bounded automaton (a nondeterministic Turing machine whose tape is bounded by a constant times the length of the input.) Type-2 grammars Type-2 grammars generate the context-free languages. These are defined by rules of the form with being a nonterminal and being a string of terminals and/or nonterminals. These languages are exactly all languages that can be recognized by a non-deterministic pushdown automaton. Context-free languages—or rather its subset of deterministic context-free language—are the theoretical basis for the phrase structure of most programming languages, though their syntax also includes context-sensitive name resolution due to declarations and scope. Often a subset of grammars is used to make parsing easier, such as by an LL parser. Type-3 grammars Type-3 grammars generate the regular languages. Such a grammar restricts its rules to a single nonterminal on the left-hand side and a right-hand side consisting of a single terminal, possibly followed by a single nonterminal (right regular). Alternatively, the right-hand side of the grammar can consist of a single terminal, possibly preceded by a single nonterminal (left regular). These generate the same languages. However, if left-regular rules and right-regular rules are combined, the language need no longer be regular. The rule is also allowed here if does not appear on the right side of any rule. These languages are exactly all languages that can be decided by a finite state automaton. Additionally, this family of formal languages can be obtained by regular expressions. Regular languages are commonly used to define search patterns and the lexical structure of programming languages.

Common Lisp (CL) is a dialect of the Lisp programming language, published in ANSI standard document ANSI INCITS 226-1994 (S20018) (formerly X3.226-1994 (R1999)). The Common Lisp HyperSpec, a hyperlinked HTML version, has been derived from the ANSI Common Lisp standard. The Common Lisp language was developed as a standardized and improved successor of Maclisp. By the early 1980s several groups were already at work on diverse successors to MacLisp: Lisp Machine Lisp (aka ZetaLisp), Spice Lisp, NIL and S-1 Lisp. Common Lisp sought to unify, standardise, and extend the features of these MacLisp dialects. Common Lisp is not an implementation, but rather a language specification. Several implementations of the Common Lisp standard are available, including free and open-source software and proprietary products. Common Lisp is a general-purpose, multi-paradigm programming language. It supports a combination of procedural, functional, and object-oriented programming paradigms. As a dynamic programming language, it facilitates evolutionary and incremental software development, with iterative compilation into efficient run-time programs. This incremental development is often done interactively without interrupting the running application. It also supports optional type annotation and casting, which can be added as necessary at the later profiling and optimization stages, to permit the compiler to generate more efficient code. For instance, fixnum can hold an unboxed integer in a range supported by the hardware and implementation, permitting more efficient arithmetic than on big integers or arbitrary precision types. Similarly, the compiler can be told on a per-module or per-function basis which type of safety level is wanted, using optimize declarations. Common Lisp includes CLOS, an object system that supports multimethods and method combinations. It is often implemented with a Metaobject Protocol. Common Lisp is extensible through standard features such as Lisp macros (code transformations) and reader macros (input parsers for characters). Common Lisp provides partial backwards compatibility with Maclisp and John McCarthy's original Lisp. This allows older Lisp software to be ported to Common Lisp. History Work on Common Lisp started in 1981 after an initiative by ARPA manager Bob Engelmore to develop a single community standard Lisp dialect. Much of the initial language design was done via electronic mail. In 1982, Guy L. Steele Jr. gave the first overview of Common Lisp at the 1982 ACM Symposium on LISP and functional programming. The first language documentation was published in 1984 as Common Lisp the Language (known as CLtL1), first edition. A second edition (known as CLtL2), published in 1990, incorporated many changes to the language, made during the ANSI Common Lisp standardization process: extended LOOP syntax, the Common Lisp Object System, the Condition System for error handling, an interface to the pretty printer and much more. But CLtL2 does not describe the final ANSI Common Lisp standard and thus is not a documentation of ANSI Common Lisp. The final ANSI Common Lisp standard then was published in 1994. Since then no update to the standard has been published. Various extensions and improvements to Common Lisp (examples are Unicode, Concurrency, CLOS-based IO) have been provided by implementations and libraries. Syntax Common Lisp is a dialect of Lisp. It uses S-expressions to denote both code and data structure. Function calls, macro forms and special forms are written as lists, with the name of the operator first, as in these examples: (+ 2 2) ; adds 2 and 2, yielding 4. The function's name is '+'. Lisp has no operators as such. (defvar *x*) ; Ensures that a variable *x* exists, ; without giving it a value. The asterisks are part of ; the name, by convention denoting a special (global) variable. ; The symbol *x* is also hereby endowed with the property that ; subsequent bindings of it are dynamic, rather than lexical. (setf *x* 42.1) ; Sets the variable *x* to the floating-point value 42.1 ;; Define a function that squares a number: (defun square (x) (* x x)) ;; Execute the function: (square 3) ; Returns 9 ;; The 'let' construct creates a scope for local variables. Here ;; the variable 'a' is bound to 6 and the variable 'b' is bound ;; to 4. Inside the 'let' is a 'body', where the last computed value is returned. ;; Here the result of adding a and b is returned from the 'let' expression. ;; The variables a and b have lexical scope, unless the symbols have been ;; marked as special variables (for instance by a prior DEFVAR). (let ((a 6) (b 4)) (+ a b)) ; returns 10 Data types Common Lisp has many data types. Scalar types Number types include integers, ratios, floating-point numbers, and complex numbers. Common Lisp uses bignums to represent numerical values of arbitrary size and precision. The ratio type represents fractions exactly, a facility not available in many languages. Common Lisp automatically coerces numeric values among these types as appropriate. The Common Lisp character type is not limited to ASCII characters. Most modern implementations allow Unicode characters. The symbol type is common to Lisp languages, but largely unknown outside them. A symbol is a unique, named data object with several parts: name, value, function, property list, and package. Of these, value cell and function cell are the most important. Symbols in Lisp are often used similarly to identifiers in other languages: to hold the value of a variable; however there are many other uses. Normally, when a symbol is evaluated, its value is returned. Some symbols evaluate to themselves, for example, all symbols in the keyword package are self-evaluating. Boolean values in Common Lisp are represented by the self-evaluating symbols T and NIL. Common Lisp has namespaces for symbols, called 'packages'. A number of functions are available for rounding scalar numeric values in various ways. The function round rounds the argument to the nearest integer, with halfway cases rounded to the even integer. The functions truncate, floor, and ceiling round towards zero, down, or up respectively. All these functions return the discarded fractional part as a secondary value. For example, (floor -2.5) yields −3, 0.5; (ceiling -2.5) yields −2, −0.5; (round 2.5) yields 2, 0.5; and (round 3.5) yields 4, −0.5. Data structures Sequence types in Common Lisp include lists, vectors, bit-vectors, and strings. There are many operations that can work on any sequence type. As in almost all other Lisp dialects, lists in Common Lisp are composed of conses, sometimes called cons cells or pairs. A cons is a data structure with two slots, called its car and cdr. A list is a linked chain of conses or the empty list. Each cons's car refers to a member of the list (possibly another list). Each cons's cdr refers to the next cons—except for the last cons in a list, whose cdr refers to the nil value. Conses can also easily be used to implement trees and other complex data structures; though it is usually advised to use structure or class instances instead. It is also possible to create circular data structures with conses. Common Lisp supports multidimensional arrays, and can dynamically resize adjustable arrays if required. Multidimensional arrays can be used for matrix mathematics. A vector is a one-dimensional array. Arrays can carry any type as members (even mixed types in the same array) or can be specialized to contain a specific type of members, as in a vector of bits. Usually, only a few types are supported. Many implementations can optimize array functions when the array used is type-specialized. Two type-specialized array types are standard: a string is a vector of characters, while a bit-vector is a vector of bits. Hash tables store associations between data objects. Any object may be used as key or value. Hash tables are automatically resized as needed. Packages are collections of symbols, used chiefly to separate the parts of a program into namespaces. A package may export some symbols, marking them as part of a public interface. Packages can use other packages. Structures, similar in use to C structs and Pascal records, represent arbitrary complex data structures with any number and type of fields (called slots). Structures allow single-inheritance. Classes are similar to structures, but offer more dynamic features and multiple-inheritance. (See CLOS). Classes have been added late to Common Lisp and there is some conceptual overlap with structures. Objects created of classes are called Instances. A special case is Generic Functions. Generic Functions are both functions and instances. Functions Common Lisp supports first-class functions. For instance, it is possible to write functions that take other functions as arguments or return functions as well. This makes it possible to describe very general operations. The Common Lisp library relies heavily on such higher-order functions. For example, the sort function takes a relational operator as an argument and key function as an optional keyword argument. This can be used not only to sort any type of data, but also to sort data structures according to a key. ;; Sorts the list using the > and < function as the relational operator. (sort (list 5 2 6 3 1 4) #'>) ; Returns (6 5 4 3 2 1) (sort (list 5 2 6 3 1 4) #'<) ; Returns (1 2 3 4 5 6) ;; Sorts the list according to the first element of each sub-list. (sort (list '(9 A) '(3 B) '(4 C)) #'< :key #'first) ; Returns ((3 B) (4 C) (9 A)) The evaluation model for functions is very simple. When the evaluator encounters a form (f a1 a2...) then it presumes that the symbol named f is one of the following: A special operator (easily checked against a fixed list) A macro operator (must have been defined previously) The name of a function (default), which may either be a symbol, or a sub-form beginning with the symbol lambda. If f is the name of a function, then the arguments a1, a2, ..., an are evaluated in left-to-right order, and the function is found and invoked with those values supplied as parameters. Defining functions The macro defun defines functions where a function definition gives the name of the function, the names of any arguments, and a function body: (defun square (x) (* x x)) Function definitions may include compiler directives, known as declarations, which provide hints to the compiler about optimization settings or the data types of arguments. They may also include documentation strings (docstrings), which the Lisp system may use to provide interactive documentation: (defun square (x) "Calculates the square of the single-float x." (declare (single-float x) (optimize (speed 3) (debug 0) (safety 1))) (the single-float (* x x))) Anonymous functions (function literals) are defined using lambda expressions, e.g. (lambda (x) (* x x)) for a function that squares its argument. Lisp programming style frequently uses higher-order functions for which it is useful to provide anonymous functions as arguments. Local functions can be defined with flet and labels. (flet ((square (x) (* x x))) (square 3)) There are several other operators related to the definition and manipulation of functions. For instance, a function may be compiled with the compile operator. (Some Lisp systems run functions using an interpreter by default unless instructed to compile; others compile every function). Defining generic functions and methods The macro defgeneric defines generic functions. Generic functions are a collection of methods. The macro defmethod defines methods. Methods can specialize their parameters over CLOS standard classes, system classes, structure classes or individual objects. For many types, there are corresponding system classes. When a generic function is called, multiple-dispatch will determine the effective method to use. (defgeneric add (a b)) (defmethod add ((a number) (b number)) (+ a b)) (defmethod add ((a vector) (b number)) (map 'vector (lambda (n) (+ n b)) a)) (defmethod add ((a vector) (b vector)) (map 'vector #'+ a b)) (defmethod add ((a string) (b string)) (concatenate 'string a b)) (add 2 3) ; returns 5 (add #(1 2 3 4) 7) ; returns #(8 9 10 11) (add #(1 2 3 4) #(4 3 2 1)) ; returns #(5 5 5 5) (add "COMMON " "LISP") ; returns "COMMON LISP" Generic Functions are also a first class data type. There are many more features to Generic Functions and Methods than described above. The function namespace The namespace for function names is separate from the namespace for data variables. This is a key difference between Common Lisp and Scheme. For Common Lisp, operators that define names in the function namespace include defun, flet, labels, defmethod and defgeneric. To pass a function by name as an argument to another function, one must use the function special operator, commonly abbreviated as #'. The first sort example above refers to the function named by the symbol > in the function namespace, with the code #'>. Conversely, to call a function passed in such a way, one would use the funcall operator on the argument. Scheme's evaluation model is simpler: there is only one namespace, and all positions in the form are evaluated (in any order) – not just the arguments. Code written in one dialect is therefore sometimes confusing to programmers more experienced in the other. For instance, many Common Lisp programmers like to use descriptive variable names such as list or string which could cause problems in Scheme, as they would locally shadow function names. Whether a separate namespace for functions is an advantage is a source of contention in the Lisp community. It is usually referred to as the Lisp-1 vs. Lisp-2 debate. Lisp-1 refers to Scheme's model and Lisp-2 refers to Common Lisp's model. These names were coined in a 1988 paper by Richard P. Gabriel and Kent Pitman, which extensively compares the two approaches. Multiple return values Common Lisp supports the concept of multiple values, where any expression always has a single primary value, but it might also have any number of secondary values, which might be received and inspected by interested callers. This concept is distinct from returning a list value, as the secondary values are fully optional, and passed via a dedicated side channel. This means that callers may remain entirely unaware of the secondary values being there if they have no need for them, and it makes it convenient to use the mechanism for communicating information that is sometimes useful, but not always necessary. For example, The TRUNCATE function rounds the given number to an integer towards zero. However, it also returns a remainder as a secondary value, making it very easy to determine what value was truncated. It also supports an optional divisor parameter, which can be used to perform Euclidean division trivially: (let ((x 1266778) (y 458)) (multiple-value-bind (quotient remainder) (truncate x y) (format nil "~A divided by ~A is ~A remainder ~A" x y quotient remainder))) ;;;; => "1266778 divided by 458 is 2765 remainder 408" GETHASH returns the value of a key in an associative map, or the default value otherwise, and a secondary boolean indicating whether the value was found. Thus code which does not care about whether the value was found or provided as the default can simply use it as-is, but when such distinction is important, it might inspect the secondary boolean and react appropriately. Both use cases are supported by the same call and neither is unnecessarily burdened or constrained by the other. Having this feature at the language level removes the need to check for the existence of the key or compare it to null as would be done in other languages. (defun get-answer (library) (gethash 'answer library 42)) (defun the-answer-1 (library) (format nil "The answer is ~A" (get-answer library))) ;;;; Returns "The answer is 42" if ANSWER not present in LIBRARY (defun the-answer-2 (library) (multiple-value-bind (answer sure-p) (get-answer library) (if (not sure-p) "I don't know" (format nil "The answer is ~A" answer)))) ;;;; Returns "I don't know" if ANSWER not present in LIBRARY Multiple values are supported by a handful of standard forms, most common of which are the MULTIPLE-VALUE-BIND special form for accessing secondary values and VALUES for returning multiple values: (defun magic-eight-ball () "Return an outlook prediction, with the probability as a secondary value" (values "Outlook good" (random 1.0))) ;;;; => "Outlook good" ;;;; => 0.3187 Other types Other data types in Common Lisp include: Pathnames represent files and directories in the filesystem. The Common Lisp pathname facility is more general than most operating systems' file naming conventions, making Lisp programs' access to files broadly portable across diverse systems. Input and output streams represent sources and sinks of binary or textual data, such as the terminal or open files. Common Lisp has a built-in pseudo-random number generator (PRNG). Random state objects represent reusable sources of pseudo-random numbers, allowing the user to seed the PRNG or cause it to replay a sequence. Conditions are a type used to represent errors, exceptions, and other "interesting" events to which a program may respond. Classes are first-class objects, and are themselves instances of classes called metaobject classes (metaclasses for short). Readtables are a type of object which control how Common Lisp's reader parses the text of source code. By controlling which readtable is in use when code is read in, the programmer can change or extend the language's syntax. Scope Like programs in many other programming languages, Common Lisp programs make use of names to refer to variables, functions, and many other kinds of entities. Named references are subject to scope. The association between a name and the entity which the name refers to is called a binding. Scope refers to the set of circumstances in which a name is determined to have a particular binding. Determiners of scope The circumstances which determine scope in Common Lisp include: the location of a reference within an expression. If it's the leftmost position of a compound, it refers to a special operator or a macro or function binding, otherwise to a variable binding or something else. the kind of expression in which the reference takes place. For instance, (go x) means transfer control to label x, whereas (print x) refers to the variable x. Both scopes of x can be active in the same region of program text, since tagbody labels are in a separate namespace from variable names. A special form or macro form has complete control over the meanings of all symbols in its syntax. For instance, in (defclass x (a b) ()), a class definition, the (a b) is a list of base classes, so these names are looked up in the space of class names, and x isn't a reference to an existing binding, but the name of a new class being derived from a and b. These facts emerge purely from the semantics of defclass. The only generic fact about this expression is that defclass refers to a macro binding; everything else is up to defclass. the location of the reference within the program text. For instance, if a reference to variable x is enclosed in a binding construct such as a let which defines a binding for x, then the reference is in the scope created by that binding. for a variable reference, whether or not a variable symbol has been, locally or globally, declared special. This determines whether the reference is resolved within a lexical environment, or within a dynamic environment. the specific instance of the environment in which the reference is resolved. An environment is a run-time dictionary which maps symbols to bindings. Each kind of reference uses its own kind of environment. References to lexical variables are resolved in a lexical environment, et cetera. More than one environment can be associated with the same reference. For instance, thanks to recursion or the use of multiple threads, multiple activations of the same function can exist at the same time. These activations share the same program text, but each has its own lexical environment instance. To understand what a symbol refers to, the Common Lisp programmer must know what kind of reference is being expressed, what kind of scope it uses if it is a variable reference (dynamic versus lexical scope), and also the run-time situation: in what environment is the reference resolved, where was the binding introduced into the environment, et cetera. Kinds of environment Global Some environments in Lisp are globally pervasive. For instance, if a new type is defined, it is known everywhere thereafter. References to that type look it up in this global environment. Dynamic One type of environment in Common Lisp is the dynamic environment. Bindings established in this environment have dynamic extent, which means that a binding is established at the start of the execution of some construct, such as a let block, and disappears when that construct finishes executing: its lifetime is tied to the dynamic activation and deactivation of a block. However, a dynamic binding is not just visible within that block; it is also visible to all functions invoked from that block. This type of visibility is known as indefinite scope. Bindings which exhibit dynamic extent (lifetime tied to the activation and deactivation of a block) and indefinite scope (visible to all functions which are called from that block) are said to have dynamic scope. Common Lisp has support for dynamically scoped variables, which are also called special variables. Certain other kinds of bindings are necessarily dynamically scoped also, such as restarts and catch tags. Function bindings cannot be dynamically scoped using flet (which only provides lexically scoped function bindings), but function objects (a first-level object in Common Lisp) can be assigned to dynamically scoped variables, bound using let in dynamic scope, then called using funcall or APPLY. Dynamic scope is extremely useful because it adds referential clarity and discipline to global variables. Global variables are frowned upon in computer science as potential sources of error, because they can give rise to ad-hoc, covert channels of communication among modules that lead to unwanted, surprising interactions. In Common Lisp, a special variable which has only a top-level binding behaves just like a global variable in other programming languages. A new value can be stored into it, and that value simply replaces what is in the top-level binding. Careless replacement of the value of a global variable is at the heart of bugs caused by the use of global variables. However, another way to work with a special variable is to give it a new, local binding within an expression. This is sometimes referred to as "rebinding" the variable. Binding a dynamically scoped variable temporarily creates a new memory location for that variable, and associates the name with that location. While that binding is in effect, all references to that variable refer to the new binding; the previous binding is hidden. When execution of the binding expression terminates, the temporary memory location is gone, and the old binding is revealed, with the original value intact. Of course, multiple dynamic bindings for the same variable can be nested. In Common Lisp implementations which support multithreading, dynamic scopes are specific to each thread of execution. Thus special variables serve as an abstraction for thread local storage. If one thread rebinds a special variable, this rebinding has no effect on that variable in other threads. The value stored in a binding can only be retrieved by the thread which created that binding. If each thread binds some special variable *x*, then *x* behaves like thread-local storage. Among threads which do not rebind *x*, it behaves like an ordinary global: all of these threads refer to the same top-level binding of *x*. Dynamic variables can be used to extend the execution context with additional context information which is implicitly passed from function to function without having to appear as an extra function parameter. This is especially useful when the control transfer has to pass through layers of unrelated code, which simply cannot be extended with extra parameters to pass the additional data. A situation like this usually calls for a global variable. That global variable must be saved and restored, so that the scheme doesn't break under recursion: dynamic variable rebinding takes care of this. And that variable must be made thread-local (or else a big mutex must be used) so the scheme doesn't break under threads: dynamic scope implementations can take care of this also. In the Common Lisp library, there are many standard special variables. For instance, all standard I/O streams are stored in the top-level bindings of well-known special variables. The standard output stream is stored in *standard-output*. Suppose a function foo writes to standard output: (defun foo () (format t "Hello, world")) To capture its output in a character string, *standard-output* can be bound to a string stream and called: (with-output-to-string (*standard-output*) (foo)) -> "Hello, world" ; gathered output returned as a string Lexical Common Lisp supports lexical environments. Formally, the bindings in a lexical environment have lexical scope and may have either an indefinite extent or dynamic extent, depending on the type of namespace. Lexical scope means that visibility is physically restricted to the block in which the binding is established. References which are not textually (i.e. lexically) embedded in that block simply do not see that binding. The tags in a TAGBODY have lexical scope. The expression (GO X) is erroneous if it is not embedded in a TAGBODY which contains a label X. However, the label bindings disappear when the TAGBODY terminates its execution, because they have dynamic extent. If that block of code is re-entered by the invocation of a lexical closure, it is invalid for the body of that closure to try to transfer control to a tag via GO: (defvar *stashed*) ;; will hold a function (tagbody (setf *stashed* (lambda () (go some-label))) (go end-label) ;; skip the (print "Hello") some-label (print "Hello") end-label) -> NIL When the TAGBODY is executed, it first evaluates the setf form which stores a function in the special variable *stashed*. Then the (go end-label) transfers control to end-label, skipping the code (print "Hello"). Since end-label is at the end of the tagbody, the tagbody terminates, yielding NIL. Suppose that the previously remembered function is now called: (funcall *stashed*) ;; Error! This situation is erroneous. One implementation's response is an error condition containing the message, "GO: tagbody for tag SOME-LABEL has already been left". The function tried to evaluate (go some-label), which is lexically embedded in the tagbody, and resolves to the label. However, the tagbody isn't executing (its extent has ended), and so the control transfer cannot take place. Local function bindings in Lisp have lexical scope, and variable bindings also have lexical scope by default. By contrast with GO labels, both of these have indefinite extent. When a lexical function or variable binding is established, that binding continues to exist for as long as references to it are possible, even after the construct which established that binding has terminated. References to lexical variables and functions after the termination of their establishing construct are possible thanks to lexical closures. Lexical binding is the default binding mode for Common Lisp variables. For an individual symbol, it can be switched to dynamic scope, either by a local declaration, by a global declaration. The latter may occur implicitly through the use of a construct like DEFVAR or DEFPARAMETER. It is an important convention in Common Lisp programming that special (i.e. dynamically scoped) variables have names which begin and end with an asterisk sigil * in what is called the "earmuff convention". If adhered to, this convention effectively creates a separate namespace for special variables, so that variables intended to be lexical are not accidentally made special. Lexical scope is useful for several reasons. Firstly, references to variables and functions can be compiled to efficient machine code, because the run-time environment structure is relatively simple. In many cases it can be optimized to stack storage, so opening and closing lexical scopes has minimal overhead. Even in cases where full closures must be generated, access to the closure's environment is still efficient; typically each variable becomes an offset into a vector of bindings, and so a variable reference becomes a simple load or store instruction with a base-plus-offset addressing mode. Secondly, lexical scope (combined with indefinite extent) gives rise to the lexical closure, which in turn creates a whole paradigm of programming centered around the use of functions being first-class objects, which is at the root of functional programming. Thirdly, perhaps most importantly, even if lexical closures are not exploited, the use of lexical scope isolates program modules from unwanted interactions. Due to their restricted visibility, lexical variables are private. If one module A binds a lexical variable X, and calls another module B, references to X in B will not accidentally resolve to the X bound in A. B simply has no access to X. For situations in which disciplined interactions through a variable are desirable, Common Lisp provides special variables. Special variables allow for a module A to set up a binding for a variable X which is visible to another module B, called from A. Being able to do this is an advantage, and being able to prevent it from happening is also an advantage; consequently, Common Lisp supports both lexical and dynamic scope. Macros A macro in Lisp superficially resembles a function in usage. However, rather than representing an expression which is evaluated, it represents a transformation of the program source code. The macro gets the source it surrounds as arguments, binds them to its parameters and computes a new source form. This new form can also use a macro. The macro expansion is repeated until the new source form does not use a macro. The final computed form is the source code executed at runtime. Typical uses of macros in Lisp: new control structures (example: looping constructs, branching constructs) scoping and binding constructs simplified syntax for complex and repeated source code top-level defining forms with compile-time side-effects data-driven programming embedded domain specific languages (examples: SQL, HTML, Prolog) implicit finalization forms Various standard Common Lisp features also need to be implemented as macros, such as: the standard setf abstraction, to allow custom compile-time expansions of assignment/access operators with-accessors, with-slots, with-open-file and other similar WITH macros Depending on implementation, if or cond is a macro built on the other, the special operator; when and unless consist of macros The powerful loop domain-specific language Macros are defined by the defmacro macro. The special operator macrolet allows the definition of local (lexically scoped) macros. It is also possible to define macros for symbols using define-symbol-macro and symbol-macrolet. Paul Graham's book On Lisp describes the use of macros in Common Lisp in detail. Doug Hoyte's book Let Over Lambda extends the discussion on macros, claiming "Macros are the single greatest advantage that lisp has as a programming language and the single greatest advantage of any programming language." Hoyte provides several examples of iterative development of macros. Example using a macro to define a new control structure Macros allow Lisp programmers to create new syntactic forms in the language. One typical use is to create new control structures. The example macro provides an until looping construct. The syntax is: (until test form*) The macro definition for until: (defmacro until (test &body body) (let ((start-tag (gensym "START")) (end-tag (gensym "END"))) `(tagbody ,start-tag (when ,test (go ,end-tag)) (progn ,@body) (go ,start-tag) ,end-tag))) tagbody is a primitive Common Lisp special operator which provides the ability to name tags and use the go form to jump to those tags. The backquote ` provides a notation that provides code templates, where the value of forms preceded with a comma are filled in. Forms preceded with comma and at-sign are spliced in. The tagbody form tests the end condition. If the condition is true, it jumps to the end tag. Otherwise, the provided body code is executed and then it jumps to the start tag. An example of using the above until macro: (until (= (random 10) 0) (write-line "Hello")) The code can be expanded using the function macroexpand-1. The expansion for the above example looks like this: (TAGBODY #:START1136 (WHEN (ZEROP (RANDOM 10)) (GO #:END1137)) (PROGN (WRITE-LINE "hello")) (GO #:START1136) #:END1137) During macro expansion the value of the variable test is (= (random 10) 0) and the value of the variable body is ((write-line "Hello")). The body is a list of forms. Symbols are usually automatically upcased. The expansion uses the TAGBODY with two labels. The symbols for these labels are computed by GENSYM and are not interned in any package. Two go forms use these tags to jump to. Since tagbody is a primitive operator in Common Lisp (and not a macro), it will not be expanded into something else. The expanded form uses the when macro, which also will be expanded. Fully expanding a source form is called code walking. In the fully expanded (walked) form, the when form is replaced by the primitive if: (TAGBODY #:START1136 (IF (ZEROP (RANDOM 10)) (PROGN (GO #:END1137)) NIL) (PROGN (WRITE-LINE "hello")) (GO #:START1136)) #:END1137) All macros must be expanded before the source code containing them can be evaluated or compiled normally. Macros can be considered functions that accept and return S-expressions – similar to abstract syntax trees, but not limited to those. These functions are invoked before the evaluator or compiler to produce the final source code. Macros are written in normal Common Lisp, and may use any Common Lisp (or third-party) operator available. Variable capture and shadowing Common Lisp macros are capable of what is commonly called variable capture, where symbols in the macro-expansion body coincide with those in the calling context, allowing the programmer to create macros wherein various symbols have special meaning. The term variable capture is somewhat misleading, because all namespaces are vulnerable to unwanted capture, including the operator and function namespace, the tagbody label namespace, catch tag, condition handler and restart namespaces. Variable capture can introduce software defects. This happens in one of the following two ways: In the first way, a macro expansion can inadvertently make a symbolic reference which the macro writer assumed will resolve in a global namespace, but the code where the macro is expanded happens to provide a local, shadowing definition which steals that reference. Let this be referred to as type 1 capture. The second way, type 2 capture, is just the opposite: some of the arguments of the macro are pieces of code supplied by the macro caller, and those pieces of code are written such that they make references to surrounding bindings. However, the macro inserts these pieces of code into an expansion which defines its own bindings that accidentally captures some of these references. The Scheme dialect of Lisp provides a macro-writing system which provides the referential transparency that eliminates both types of capture problem. This type of macro system is sometimes called "hygienic", in particular by its proponents (who regard macro systems which do not automatically solve this problem as unhygienic). In Common Lisp, macro hygiene is ensured one of two different ways. One approach is to use gensyms: guaranteed-unique symbols which can be used in a macro-expansion without threat of capture. The use of gensyms in a macro definition is a manual chore, but macros can be written which simplify the instantiation and use of gensyms. Gensyms solve type 2 capture easily, but they are not applicable to type 1 capture in the same way, because the macro expansion cannot rename the interfering symbols in the surrounding code which capture its references. Gensyms could be used to provide stable aliases for the global symbols which the macro expansion needs. The macro expansion would use these secret aliases rather than the well-known names, so redefinition of the well-known names would have no ill effect on the macro. Another approach is to use packages. A macro defined in its own package can simply use internal symbols in that package in its expansion. The use of packages deals with type 1 and type 2 capture. However, packages don't solve the type 1 capture of references to standard Common Lisp functions and operators. The reason is that the use of packages to solve capture problems revolves around the use of private symbols (symbols in one package, which are not imported into, or otherwise made visible in other packages). Whereas the Common Lisp library symbols are external, and frequently imported into or made visible in user-defined packages. The following is an example of unwanted capture in the operator namespace, occurring in the expansion of a macro: ;; expansion of UNTIL makes liberal use of DO (defmacro until (expression &body body) `(do () (,expression) ,@body)) ;; macrolet establishes lexical operator binding for DO (macrolet ((do (...) ... something else ...)) (until (= (random 10) 0) (write-line "Hello"))) The until macro will expand into a form which calls do which is intended to refer to the standard Common Lisp macro do. However, in this context, do may have a completely different meaning, so until may not work properly. Common Lisp solves the problem of the shadowing of standard operators and functions by forbidding their redefinition. Because it redefines the standard operator do, the preceding is actually a fragment of non-conforming Common Lisp, which allows implementations to diagnose and reject it. Condition system The condition system is responsible for exception handling in Common Lisp. It provides conditions, handlers and restarts. Conditions are objects describing an exceptional situation (for example an error). If a condition is signaled, the Common Lisp system searches for a handler for this condition type and calls the handler. The handler can now search for restarts and use one of these restarts to automatically repair the current problem, using information such as the condition type and any relevant information provided as part of the condition object, and call the appropriate restart function. These restarts, if unhandled by code, can be presented to users (as part of a user interface, that of a debugger for example), so that the user can select and invoke one of the available restarts. Since the condition handler is called in the context of the error (without unwinding the stack), full error recovery is possible in many cases, where other exception handling systems would have already terminated the current routine. The debugger itself can also be customized or replaced using the *debugger-hook* dynamic variable. Code found within unwind-protect forms such as finalizers will also be executed as appropriate despite the exception. In the following example (using Symbolics Genera) the user tries to open a file in a Lisp function test called from the Read-Eval-Print-LOOP (REPL), when the file does not exist. The Lisp system presents four restarts. The user selects the Retry OPEN using a different pathname restart and enters a different pathname (lispm-init.lisp instead of lispm-int.lisp). The user code does not contain any error handling code. The whole error handling and restart code is provided by the Lisp system, which can handle and repair the error without terminating the user code. Command: (test ">zippy>lispm-int.lisp") Error: The file was not found. For lispm:>zippy>lispm-int.lisp.newest LMFS:OPEN-LOCAL-LMFS-1 Arg 0: #P"lispm:>zippy>lispm-int.lisp.newest" s-A, <Resume>: Retry OPEN of lispm:>zippy>lispm-int.lisp.newest s-B: Retry OPEN using a different pathname s-C, <Abort>: Return to Lisp Top Level in a TELNET server s-D: Restart process TELNET terminal -> Retry OPEN using a different pathname Use what pathname instead [default lispm:>zippy>lispm-int.lisp.newest]: lispm:>zippy>lispm-init.lisp.newest ...the program continues Common Lisp Object System (CLOS) Common Lisp includes a toolkit for object-oriented programming, the Common Lisp Object System or CLOS, which is one of the most powerful object systems available in any language. For example, Peter Norvig explains how many Design Patterns are simpler to implement in a dynamic language with the features of CLOS (Multiple Inheritance, Mixins, Multimethods, Metaclasses, Method combinations, etc.). Several extensions to Common Lisp for object-oriented programming have been proposed to be included into the ANSI Common Lisp standard, but eventually CLOS was adopted as the standard object-system for Common Lisp. CLOS is a dynamic object system with multiple dispatch and multiple inheritance, and differs radically from the OOP facilities found in static languages such as C++ or Java. As a dynamic object system, CLOS allows changes at runtime to generic functions and classes. Methods can be added and removed, classes can be added and redefined, objects can be updated for class changes and the class of objects can be changed. CLOS has been integrated into ANSI Common Lisp. Generic functions can be used like normal functions and are a first-class data type. Every CLOS class is integrated into the Common Lisp type system. Many Common Lisp types have a corresponding class. There is more potential use of CLOS for Common Lisp. The specification does not say whether conditions are implemented with CLOS. Pathnames and streams could be implemented with CLOS. These further usage possibilities of CLOS for ANSI Common Lisp are not part of the standard. Actual Common Lisp implementations use CLOS for pathnames, streams, input–output, conditions, the implementation of CLOS itself and more. Compiler and interpreter A Lisp interpreter directly executes Lisp source code provided as Lisp objects (lists, symbols, numbers, ...) read from s-expressions. A Lisp compiler generates bytecode or machine code from Lisp source code. Common Lisp allows both individual Lisp functions to be compiled in memory and the compilation of whole files to externally stored compiled code (fasl files). Several implementations of earlier Lisp dialects provided both an interpreter and a compiler. Unfortunately often the semantics were different. These earlier Lisps implemented lexical scoping in the compiler and dynamic scoping in the interpreter. Common Lisp requires that both the interpreter and compiler use lexical scoping by default. The Common Lisp standard describes both the semantics of the interpreter and a compiler. The compiler can be called using the function compile for individual functions and using the function compile-file for files. Common Lisp allows type declarations and provides ways to influence the compiler code generation policy. For the latter various optimization qualities can be given values between 0 (not important) and 3 (most important): speed, space, safety, debug and compilation-speed. There is also a function to evaluate Lisp code: eval. eval takes code as pre-parsed s-expressions and not, like in some other languages, as text strings. This way code can be constructed with the usual Lisp functions for constructing lists and symbols and then this code can be evaluated with the function eval. Several Common Lisp implementations (like Clozure CL and SBCL) are implementing eval using their compiler. This way code is compiled, even though it is evaluated using the function eval. The file compiler is invoked using the function compile-file. The generated file with compiled code is called a fasl (from fast load) file. These fasl files and also source code files can be loaded with the function load into a running Common Lisp system. Depending on the implementation, the file compiler generates byte-code (for example for the Java Virtual Machine), C language code (which then is compiled with a C compiler) or, directly, native code. Common Lisp implementations can be used interactively, even though the code gets fully compiled. The idea of an Interpreted language thus does not apply for interactive Common Lisp. The language makes a distinction between read-time, compile-time, load-time, and run-time, and allows user code to also make this distinction to perform the wanted type of processing at the wanted step. Some special operators are provided to especially suit interactive development; for instance, defvar will only assign a value to its provided variable if it wasn't already bound, while defparameter will always perform the assignment. This distinction is useful when interactively evaluating, compiling and loading code in a live image. Some features are also provided to help writing compilers and interpreters. Symbols consist of first-level objects and are directly manipulable by user code. The progv special operator allows to create lexical bindings programmatically, while packages are also manipulable. The Lisp compiler is available at runtime to compile files or individual functions. These make it easy to use Lisp as an intermediate compiler or interpreter for another language. Code examples Birthday paradox The following program calculates the smallest number of people in a room for whom the probability of unique birthdays is less than 50% (the birthday paradox, where for 1 person the probability is obviously 100%, for 2 it is 364/365, etc.). The answer is 23. By convention, constants in Common Lisp are enclosed with + characters. (defconstant +year-size+ 365) (defun birthday-paradox (probability number-of-people) (let ((new-probability (* (/ (- +year-size+ number-of-people) +year-size+) probability))) (if (< new-probability 0.5) (1+ number-of-people) (birthday-paradox new-probability (1+ number-of-people))))) Calling the example function using the REPL (Read Eval Print Loop): CL-USER > (birthday-paradox 1.0 1) 23 Sorting a list of person objects We define a class person and a method for displaying the name and age of a person.

Scheme predates CL, and comes not only from the same Lisp tradition but from some of the same engineers—Guy L. Steele, with whom Gerald Jay Sussman designed Scheme, chaired the standards committee for Common Lisp. Common Lisp is a general-purpose programming language, in contrast to Lisp variants such as Emacs Lisp and AutoLISP which are extension languages embedded in particular products (GNU Emacs and AutoCAD, respectively). Unlike many earlier Lisps, Common Lisp (like Scheme) uses lexical variable scope by default for both interpreted and compiled code. Most of the Lisp systems whose designs contributed to Common Lisp—such as ZetaLisp and Franz Lisp—used dynamically scoped variables in their interpreters and lexically scoped variables in their compilers. Scheme introduced the sole use of lexically scoped variables to Lisp; an inspiration from ALGOL 68. CL supports dynamically scoped variables as well, but they must be explicitly declared as "special". There are no differences in scoping between ANSI CL interpreters and compilers. Common Lisp is sometimes termed a Lisp-2 and Scheme a Lisp-1, referring to CL's use of separate namespaces for functions and variables. (In fact, CL has many namespaces, such as those for go tags, block names, and loop keywords). There is a long-standing controversy between CL and Scheme advocates over the tradeoffs involved in multiple namespaces. In Scheme, it is (broadly) necessary to avoid giving variables names which clash with functions; Scheme functions frequently have arguments named lis, lst, or lyst so as not to conflict with the system function list. However, in CL it is necessary to explicitly refer to the function namespace when passing a function as an argument—which is also a common occurrence, as in the sort example above. CL also differs from Scheme in its handling of boolean values. Scheme uses the special values #t and #f to represent truth and falsity. CL follows the older Lisp convention of using the symbols T and NIL, with NIL standing also for the empty list. In CL, any non-NIL value is treated as true by conditionals, such as if, whereas in Scheme all non-#f values are treated as true. These conventions allow some operators in both languages to serve both as predicates (answering a boolean-valued question) and as returning a useful value for further computation, but in Scheme the value '() which is equivalent to NIL in Common Lisp evaluates to true in a boolean expression. Lastly, the Scheme standards documents require tail-call optimization, which the CL standard does not. Most CL implementations do offer tail-call optimization, although often only when the programmer uses an optimization directive. Nonetheless, common CL coding style does not favor the ubiquitous use of recursion that Scheme style prefers—what a Scheme programmer would express with tail recursion, a CL user would usually express with an iterative expression in do, dolist, loop, or (more recently) with the iterate package. Implementations See the Category Common Lisp implementations. Common Lisp is defined by a specification (like Ada and C) rather than by one implementation (like Perl). There are many implementations, and the standard details areas in which they may validly differ. In addition, implementations tend to come with extensions, which provide functionality not covered in the standard: Interactive Top-Level (REPL) Debugger, Stepper and Inspector Weak data structures (hash tables) Extensible sequences Extensible LOOP Environment access CLOS Meta-object Protocol CLOS based extensible streams CLOS based Condition System Network streams Persistent CLOS Unicode support Foreign-Language Interface (often to C) Operating System interface Java Interface Threads and Multiprocessing Application delivery (applications, dynamic libraries) Saving of images Free and open-source software libraries have been created to support extensions to Common Lisp in a portable way, and are most notably found in the repositories of the Common-Lisp.net and CLOCC (Common Lisp Open Code Collection) projects. Common Lisp implementations may use any mix of native code compilation, byte code compilation or interpretation. Common Lisp has been designed to support incremental compilers, file compilers and block compilers. Standard declarations to optimize compilation (such as function inlining or type specialization) are proposed in the language specification. Most Common Lisp implementations compile source code to native machine code. Some implementations can create (optimized) stand-alone applications. Others compile to interpreted bytecode, which is less efficient than native code, but eases binary-code portability. Some compilers compile Common Lisp code to C code. The misconception that Lisp is a purely interpreted language is most likely because Lisp environments provide an interactive prompt and that code is compiled one-by-one, in an incremental way. With Common Lisp incremental compilation is widely used. Some Unix-based implementations (CLISP, SBCL) can be used as a scripting language; that is, invoked by the system transparently in the way that a Perl or Unix shell interpreter is.

It is also possible to embed ECL in C programs, and C code into Common Lisp programs. GNU Common Lisp (GCL) The GNU Project's Lisp compiler. Not yet fully ANSI-compliant, GCL is however the implementation of choice for several large projects including the mathematical tools Maxima, AXIOM and (historically) ACL2.

Carbon monoxide (chemical formula CO) is a colorless, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. Thermal combustion is the most common source of carbon monoxide, however there are numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. Carbon monoxide is important in the production of many compounds ranging from drugs, fragrances, and fuels. It is produced by many organisms, including humans. Upon emission into the atmosphere, carbon monoxide may have roles potentially affecting climate change. Carbon monoxide has important biological roles across phylogenetic kingdoms. In mammalian physiology, carbon monoxide is a classical example of hormesis where low concentrations serve as an endogenous neurotransmitter (gasotransmitter) and high concentrations are toxic resulting in carbon monoxide poisoning. It is isoelectronic with cyanide anion CN−. History Prehistory Humans have maintained a complex relationship with carbon monoxide since first learning to control fire circa 800,000 BC. Early humans probably discovered the toxicity of carbon monoxide poisoning upon introducing fire into their dwellings. The early development of metallurgy and smelting technologies emerging circa 6,000 BC through the Bronze Age likewise plagued humankind from carbon monoxide exposure. Apart from the toxicity of carbon monoxide, indigenous Native Americans may have experienced the neuroactive properties of carbon monoxide through shamanistic fireside rituals. Ancient history Early civilizations developed mythological tales to explain the origin of fire, such as Prometheus from Greek mythology who shared fire with humans. Aristotle (384–322 BC) first recorded that burning coals produced toxic fumes. Greek physician Galen (129–199 AD) speculated that there was a change in the composition of the air that caused harm when inhaled, and many others of the era developed a basis of knowledge about carbon monoxide in the context of coal fume toxicity. Cleopatra may have died from carbon monoxide poisoning. Pre-Industrial Revolution Georg Ernst Stahl mentioned carbonarii halitus in 1697 in reference to toxic vapors thought to be carbon monoxide. Friedrich Hoffmann conducted the first modern scientific investigation into carbon monoxide poisoning from coal in 1716. Herman Boerhaave conducted the first scientific experiments on the effect of carbon monoxide (coal fumes) on animals in the 1730s. Joseph Priestley is considered to have first synthesized carbon monoxide in 1772. Carl Wilhelm Scheele similarly isolated carbon monoxide from charcoal in 1773 and thought it could be the carbonic entity making fumes toxic. Torbern Bergman isolated carbon monoxide from oxalic acid in 1775. Later in 1776, the French chemist produced CO by heating zinc oxide with coke, but mistakenly concluded that the gaseous product was hydrogen, as it burned with a blue flame. In the presence of oxygen, including atmospheric concentrations, carbon monoxide burns with a blue flame, producing carbon dioxide. Antoine Lavoisier conducted similar inconclusive experiments to Lassone in 1777. The gas was identified as a compound containing carbon and oxygen by William Cruickshank in 1800. Thomas Beddoes and James Watt recognized carbon monoxide (as hydrocarbonate) to brighten venous blood in 1793. Watt suggested coal fumes could act as an antidote to the oxygen in blood, and Beddoes and Watt likewise suggested hydrocarbonate has a greater affinity for animal fiber than oxygen in 1796. In 1854, Adrien Chenot similarly suggested carbon monoxide to remove the oxygen from blood and then be oxidized by the body to carbon dioxide. The mechanism for carbon monoxide poisoning is widely credited to Claude Bernard whose memoirs beginning in 1846 and published in 1857 which phrased, "prevents arterials blood from becoming venous". Felix Hoppe-Seyler independently published similar conclusions in the following year. Advent of industrial chemistry Carbon monoxide gained recognition as an invaluable reagent in the 1900s. Three industrial processes illustrate its evolution in industry. In the Fischer-Tropsch process, coal and related carbon-rich feedstocks are converted into liquid fuels via the intermediacy of CO. Originally developed as part of the German war effort to compensate for their lack of domestic petroleum, this technology continues today. Also in Germany, a mixture of CO and hydrogen was found to combine with olefins to give aldehydes. This process, called hydroformylation, is used to produce many large scale chemicals such as surfactants as well as specialty compounds that are popular fragrances and drugs. One example, CO is used in the production of vitamin A. In a third major process, attributed to researchers at Monsanto, CO combines with methanol to give acetic acid. Most acetic acid is produced by the Cativa process. Hydroformylation and the acetic acid syntheses are two of myriad carbonylation processes. Physical and chemical properties Carbon monoxide is the simplest oxocarbon and is isoelectronic with other triply-bonded diatomic species possessing 10 valence electrons, including the cyanide anion, the nitrosonium cation, boron monofluoride and molecular nitrogen. It has a molar mass of 28.0, which, according to the ideal gas law, makes it slightly less dense than air, whose average molar mass is 28.8. The carbon and oxygen are connected by a triple bond that consists of a net two pi bonds and one sigma bond. The bond length between the carbon atom and the oxygen atom is 112.8 pm. This bond length is consistent with a triple bond, as in molecular nitrogen (N2), which has a similar bond length (109.76 pm) and nearly the same molecular mass. Carbon–oxygen double bonds are significantly longer, 120.8 pm in formaldehyde, for example. The boiling point (82 K) and melting point (68 K) are very similar to those of N2 (77 K and 63 K, respectively). The bond-dissociation energy of 1072 kJ/mol is stronger than that of N2 (942 kJ/mol) and represents the strongest chemical bond known. The ground electronic state of carbon monoxide is a singlet state since there are no unpaired electrons. Bonding and dipole moment Carbon and oxygen together have a total of 10 electrons in the valence shell. Following the octet rule for both carbon and oxygen, the two atoms form a triple bond, with six shared electrons in three bonding molecular orbitals, rather than the usual double bond found in organic carbonyl compounds. Since four of the shared electrons come from the oxygen atom and only two from carbon, one bonding orbital is occupied by two electrons from oxygen, forming a dative or dipolar bond. This causes a C←O polarization of the molecule, with a small negative charge on carbon and a small positive charge on oxygen. The other two bonding orbitals are each occupied by one electron from carbon and one from oxygen, forming (polar) covalent bonds with a reverse C→O polarization since oxygen is more electronegative than carbon. In the free carbon monoxide molecule, a net negative charge δ– remains at the carbon end and the molecule has a small dipole moment of 0.122 D. The molecule is therefore asymmetric: oxygen has more electron density than carbon and is also slightly positively charged compared to carbon being negative. By contrast, the isoelectronic dinitrogen molecule has no dipole moment. Carbon monoxide has a computed fractional bond order of 2.6, indicating that the "third" bond is important but constitutes somewhat less than a full bond. Thus, in valence bond terms, –C≡O+ is the most important structure, while :C=O is non-octet, but has a neutral formal charge on each atom and represents the second most important resonance contributor. Because of the lone pair and divalence of carbon in this resonance structure, carbon monoxide is often considered to be an extraordinarily stabilized carbene. Isocyanides are compounds in which the O is replaced by an NR (R = alkyl or aryl) group and have a similar bonding scheme. If carbon monoxide acts as a ligand, the polarity of the dipole may reverse with a net negative charge on the oxygen end, depending on the structure of the coordination complex. See also the section "Coordination chemistry" below. Bond polarity and oxidation state Theoretical and experimental studies show that, despite the greater electronegativity of oxygen, the dipole moment points from the more-negative carbon end to the more-positive oxygen end. The three bonds are in fact polar covalent bonds that are strongly polarized. The calculated polarization toward the oxygen atom is 71% for the σ-bond and 77% for both π-bonds. The oxidation state of carbon in carbon monoxide is +2 in each of these structures. It is calculated by counting all the bonding electrons as belonging to the more electronegative oxygen. Only the two non-bonding electrons on carbon are assigned to carbon. In this count, carbon then has only two valence electrons in the molecule compared to four in the free atom. Occurrence Carbon monoxide occurs in various natural and artificial environments. Photochemical degradation of plant matter for example generates an estimated 60 billion kilograms/year.Typical concentrations in parts per million are as follows: Atmospheric presence Carbon monoxide (CO) is present in small amounts (about 80 ppb) in the Earth's atmosphere. Most of the rest comes from chemical reactions with organic compounds emitted by human activities and natural origins due to photochemical reactions in the troposphere that generate about 5×1012 kilograms per year. Other natural sources of CO include volcanoes, forest and bushfires fires, and miscellaneous other forms of combustion such as fossil fuels. Small amounts are also emitted from the ocean, and from geological activity because carbon monoxide occurs dissolved in molten volcanic rock at high pressures in the Earth's mantle. Because natural sources of carbon monoxide are so variable from year to year, it is difficult to accurately measure natural emissions of the gas. Carbon monoxide has an indirect effect on radiative forcing by elevating concentrations of direct greenhouse gases, including methane and tropospheric ozone. CO can react chemically with other atmospheric constituents (primarily the hydroxyl radical, OH.) that would otherwise destroy methane. Through natural processes in the atmosphere, it is oxidized to carbon dioxide and ozone. Carbon monoxide is short-lived in the atmosphere (with an average lifetime of about one to two months), and spatially variable in concentration. Due to its long lifetime in the mid-troposphere, carbon monoxide is also used as tracer for pollutant plumes. Pollution Urban pollution Carbon monoxide is a temporary atmospheric pollutant in some urban areas, chiefly from the exhaust of internal combustion engines (including vehicles, portable and back-up generators, lawnmowers, power washers, etc.), but also from incomplete combustion of various other fuels (including wood, coal, charcoal, oil, paraffin, propane, natural gas, and trash). Large CO pollution events can be observed from space over cities. Role in ground level ozone formation Carbon monoxide is, along with aldehydes, part of the series of cycles of chemical reactions that form photochemical smog. It reacts with hydroxyl radical (•OH) to produce a radical intermediate •HOCO, which transfers rapidly its radical hydrogen to O2 to form peroxy radical (HO2•) and carbon dioxide (). Peroxy radical subsequently reacts with nitrogen oxide (NO) to form nitrogen dioxide (NO2) and hydroxyl radical. NO2 gives O(3P) via photolysis, thereby forming O3 following reaction with O2. Since hydroxyl radical is formed during the formation of NO2, the balance of the sequence of chemical reactions starting with carbon monoxide and leading to the formation of ozone is: CO + 2O2 + hν → + O3 (where hν refers to the photon of light absorbed by the NO2 molecule in the sequence) Although the creation of NO2 is the critical step leading to low level ozone formation, it also increases this ozone in another, somewhat mutually exclusive way, by reducing the quantity of NO that is available to react with ozone. Indoor pollution In closed environments, the concentration of carbon monoxide can rise to lethal levels. On average, 170 people in the United States die every year from carbon monoxide produced by non-automotive consumer products. These products include malfunctioning fuel-burning appliances such as furnaces, ranges, water heaters, and gas and kerosene room heaters; engine-powered equipment such as portable generators (and cars left running in attached garages); fireplaces; and charcoal that is burned in homes and other enclosed areas. Many deaths have occurred during power outages due to severe weather such as Hurricane Katrina and the 2021 Texas power crisis. Astronomy Beyond Earth, carbon monoxide is the second-most common diatomic molecule in the interstellar medium, after molecular hydrogen. Because of its asymmetry, this polar molecule produces far brighter spectral lines than the hydrogen molecule, making CO much easier to detect. Interstellar CO was first detected with radio telescopes in 1970. It is now the most commonly used tracer of molecular gas in general in the interstellar medium of galaxies, as molecular hydrogen can only be detected using ultraviolet light, which requires space telescopes. Carbon monoxide observations provide much of the information about the molecular clouds in which most stars form. Beta Pictoris, the second brightest star in the constellation Pictor, shows an excess of infrared emission compared to normal stars of its type, which is caused by large quantities of dust and gas (including carbon monoxide) near the star. In the atmosphere of Venus carbon monoxide occurs as a result of the photodissociation of carbon dioxide by electromagnetic radiation of wavelengths shorter than 169 nm. It has also been identified spectroscopically on the surface of Neptune's moon Triton. Solid carbon monoxide is a component of comets. Halley's Comet is about 15% carbon monoxide. At room temperature and at atmospheric pressure, carbon monoxide is actually only metastable (see Boudouard reaction) and the same is true at low temperatures where CO and are solid, but nevertheless it can exist for billions of years in comets. There is very little CO in the atmosphere of Pluto, which seems to have been formed from comets. This may be because there is (or was) liquid water inside Pluto. Carbon monoxide can react with water to form carbon dioxide and hydrogen: CO + H2O → + This is called the water-gas shift reaction when occurring in the gas phase, but it can also take place (very slowly) in an aqueous solution. If the hydrogen partial pressure is high enough (for instance in an underground sea), formic acid will be formed: CO + H2O → HCOOH These reactions can take place in a few million years even at temperatures such as found on Pluto. Niche uses Carbon monoxide has been proposed for use as a fuel on Mars. Carbon monoxide/oxygen engines have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced from the carbon dioxide atmosphere of Mars by zirconia electrolysis, without using any Martian water resources to obtain hydrogen, which would be needed to make methane or any hydrogen-based fuel. Chemistry Carbon monoxide has a wide range of functions across all disciplines of chemistry. The four premier categories of reactivity involve metal-carbonyl catalysis, radical chemistry, cation and anion chemistries. Coordination chemistry Most metals form coordination complexes containing covalently attached carbon monoxide. Only metals in lower oxidation states will complex with carbon monoxide ligands. This is because there must be sufficient electron density to facilitate back-donation from the metal dxz-orbital, to the π* molecular orbital from CO. The lone pair on the carbon atom in CO also donates electron density to the dx²−y² on the metal to form a sigma bond. This electron donation is also exhibited with the cis effect, or the labilization of CO ligands in the cis position. Nickel carbonyl, for example, forms by the direct combination of carbon monoxide and nickel metal: Ni + 4 CO → Ni(CO)4 (1 bar, 55 °C) For this reason, nickel in any tubing or part must not come into prolonged contact with carbon monoxide. Nickel carbonyl decomposes readily back to Ni and CO upon contact with hot surfaces, and this method is used for the industrial purification of nickel in the Mond process. In nickel carbonyl and other carbonyls, the electron pair on the carbon interacts with the metal; the carbon monoxide donates the electron pair to the metal. In these situations, carbon monoxide is called the carbonyl ligand. One of the most important metal carbonyls is iron pentacarbonyl, Fe(CO)5: Many metal-CO complexes are prepared by decarbonylation of organic solvents, not from CO. For instance, iridium trichloride and triphenylphosphine react in boiling 2-methoxyethanol or DMF to afford IrCl(CO)(PPh3)2. Metal carbonyls in coordination chemistry are usually studied using infrared spectroscopy. Organic and main group chemistry In the presence of strong acids and water, carbon monoxide reacts with alkenes to form carboxylic acids in a process known as the Koch–Haaf reaction. In the Gattermann–Koch reaction, arenes are converted to benzaldehyde derivatives in the presence of AlCl3 and HCl. Organolithium compounds (e.g. butyl lithium) react with carbon monoxide, but these reactions have little scientific use. Although CO reacts with carbocations and carbanions, it is relatively nonreactive toward organic compounds without the intervention of metal catalysts. With main group reagents, CO undergoes several noteworthy reactions. Chlorination of CO is the industrial route to the important compound phosgene. With borane CO forms the adduct H3BCO, which is isoelectronic with the acetylium cation [H3CCO]+. CO reacts with sodium to give products resulting from C-C coupling such as sodium acetylenediolate 2·. It reacts with molten potassium to give a mixture of an organometallic compound, potassium acetylenediolate 2·, potassium benzenehexolate 6 , and potassium rhodizonate 2·. The compounds cyclohexanehexone or triquinoyl (C6O6) and cyclopentanepentone or leuconic acid (C5O5), which so far have been obtained only in trace amounts, can be regarded as polymers of carbon monoxide. At pressures exceeding 5 GPa, carbon monoxide converts to polycarbonyl, an solid polymer that is metastable at atmospheric pressure but is explosive. Laboratory preparation Carbon monoxide is conveniently produced in the laboratory by the dehydration of formic acid or oxalic acid, for example with concentrated sulfuric acid. Another method is heating an intimate mixture of powdered zinc metal and calcium carbonate, which releases CO and leaves behind zinc oxide and calcium oxide: Zn + CaCO3 → ZnO + CaO + CO Silver nitrate and iodoform also afford carbon monoxide: CHI3 + 3AgNO3 + H2O → 3HNO3 + CO + 3AgI Finally, metal oxalate salts release CO upon heating, leaving a carbonate as byproduct: → + Production Thermal combustion is the most common source for carbon monoxide. Carbon monoxide is produced from the partial oxidation of carbon-containing compounds; it forms when there is not enough oxygen to produce carbon dioxide (), such as when operating a stove or an internal combustion engine in an enclosed space. For example, during World War II, a gas mixture including carbon monoxide was used to keep motor vehicles running in parts of the world where gasoline and diesel fuel were scarce. External (with a few exceptions) charcoals or wood gas generators were fitted, and the mixture of atmospheric nitrogen, hydrogen, carbon monoxide, and small amounts of other gases produced by gasification was piped to a gas mixer. The gas mixture produced by this process is known as wood gas. A large quantity of CO byproduct is formed during the oxidative processes for the production of chemicals. For this reason, the process off-gases have to be purified. On the other hand, considerable research efforts are made in order to optimize the process conditions, develop catalyst with improved selectivity and to understand the reaction pathways leading to the target product and side products. Many methods have been developed for carbon monoxide production. Industrial production A major industrial source of CO is producer gas, a mixture containing mostly carbon monoxide and nitrogen, formed by combustion of carbon in air at high temperature when there is an excess of carbon. In an oven, air is passed through a bed of coke. The initially produced equilibrates with the remaining hot carbon to give CO. The reaction of with carbon to give CO is described as the Boudouard reaction. Above 800 °C, CO is the predominant product: + C → 2 CO (ΔH = 170 kJ/mol) Another source is "water gas", a mixture of hydrogen and carbon monoxide produced via the endothermic reaction of steam and carbon: H2O + C → H2 + CO (ΔH = +131 kJ/mol) Other similar "synthesis gases" can be obtained from natural gas and other fuels. Carbon monoxide can also be produced by high-temperature electrolysis of carbon dioxide with solid oxide electrolyzer cells: One method, developed at DTU Energy uses a cerium oxide catalyst and does not have any issues of fouling of the catalyst 2 → 2 CO + O2 Carbon monoxide is also a byproduct of the reduction of metal oxide ores with carbon, shown in a simplified form as follows: MO + C → M + CO Carbon monoxide is also produced by the direct oxidation of carbon in a limited supply of oxygen or air. 2 C(s) + O2 → 2 CO(g) Since CO is a gas, the reduction process can be driven by heating, exploiting the positive (favorable) entropy of reaction. The Ellingham diagram shows that CO formation is favored over in high temperatures. Chemical industry Carbon monoxide is an industrial gas that has many applications in bulk chemicals manufacturing. Large quantities of aldehydes are produced by the hydroformylation reaction of alkenes, carbon monoxide, and H2. Hydroformylation is coupled to the Shell higher olefin process to give precursors to detergents. Phosgene, useful for preparing isocyanates, polycarbonates, and polyurethanes, is produced by passing purified carbon monoxide and chlorine gas through a bed of porous activated carbon, which serves as a catalyst. World production of this compound was estimated to be 2.74 million tonnes in 1989. CO + Cl2 → COCl2 Methanol is produced by the hydrogenation of carbon monoxide. In a related reaction, the hydrogenation of carbon monoxide is coupled to C-C bond formation, as in the Fischer–Tropsch process where carbon monoxide is hydrogenated to liquid hydrocarbon fuels. This technology allows coal or biomass to be converted to diesel. In the Cativa process, carbon monoxide and methanol react in the presence of a homogeneous Iridium catalyst and hydroiodic acid to give acetic acid. This process is responsible for most of the industrial production of acetic acid. Metallurgy Carbon monoxide is a strong reductive agent and has been used in pyrometallurgy to reduce metals from ores since ancient times. Carbon monoxide strips oxygen off metal oxides, reducing them to pure metal in high temperatures, forming carbon dioxide in the process. Carbon monoxide is not usually supplied as is, in the gaseous phase, in the reactor, but rather it is formed in high temperature in presence of oxygen-carrying ore, or a carboniferous agent such as coke, and high temperature. The blast furnace process is a typical example of a process of reduction of metal from ore with carbon monoxide. Likewise, blast furnace gas collected at the top of blast furnace, still contains some 10% to 30% of carbon monoxide, and is used as fuel on Cowper stoves and on Siemens-Martin furnaces on open hearth steelmaking. Mining Miners refer to carbon monoxide as "whitedamp" or the "silent killer". It can be found in confined areas of poor ventilation in both surface mines and underground mines. The most common sources of carbon monoxide in mining operations are the internal combustion engine and explosives, however in coal mines, carbon monoxide can also be found due to the low-temperature oxidation of coal. The idiom "Canary in the coal mine" pertained to an early warning of a carbon monoxide presence. Biological and physiological properties Physiology Carbon monoxide is a bioactive molecule which acts as a gaseous signaling molecule. It is naturally produced by many enzymatic and non-enzymatic pathways, the best understood of which is the catabolic action of heme oxygenase on the heme derived from hemoproteins such as hemoglobin. Following the first report that carbon monoxide is a normal neurotransmitter in 1993, carbon monoxide has received significant clinical attention as a biological regulator. Because of carbon monoxide's role in the body, abnormalities in its metabolism have been linked to a variety of diseases, including neurodegenerations, hypertension, heart failure, and pathological inflammation. In many tissues, carbon monoxide acts as anti-inflammatory, vasodilatory, and encouragers of neovascular growth. In animal model studies, carbon monoxide reduced the severity of experimentally induced bacterial sepsis, pancreatitis, hepatic ischemia/reperfusion injury, colitis, osteoarthritis, lung injury, lung transplantation rejection, and neuropathic pain while promoting skin wound healing. Therefore, there is significant interest in the therapeutic potential of carbon monoxide becoming pharmaceutical agent and clinical standard of care. Medicine Studies involving carbon monoxide have been conducted in many laboratories throughout the world for its anti-inflammatory and cytoprotective properties. These properties have the potential to be used to prevent the development of a series of pathological conditions including ischemia reperfusion injury, transplant rejection, atherosclerosis, severe sepsis, severe malaria, or autoimmunity. Many pharmaceutical drug delivery initiatives have developed methods to safely administer carbon monoxide, and subsequent controlled clinical trials have evaluated the therapeutic effect of carbon monoxide. Microbiology Microbiota may also utilize carbon monoxide as a gasotransmitter. Carbon monoxide sensing is a signaling pathway facilitated by proteins such as CooA. The scope of the biological roles for carbon monoxide sensing is still unknown. The human microbiome produces, consumes, and responds to carbon monoxide. For example, in certain bacteria, carbon monoxide is produced via the reduction of carbon dioxide by the enzyme carbon monoxide dehydrogenase with favorable bioenergetics to power downstream cellular operations. In another example, carbon monoxide is a nutrient for methanogenic archaea which reduce it to methane using hydrogen. Carbon monoxide has certain antimicrobial properties which have been studied to treat against infectious diseases. Food science Carbon monoxide is used in modified atmosphere packaging systems in the US, mainly with fresh meat products such as beef, pork, and fish to keep them looking fresh. The benefit is two-fold, carbon monoxide protects against microbial spoilage and it enhances the meat color for consumer appeal. The carbon monoxide combines with myoglobin to form carboxymyoglobin, a bright-cherry-red pigment. Carboxymyoglobin is more stable than the oxygenated form of myoglobin, oxymyoglobin, which can become oxidized to the brown pigment metmyoglobin. This stable red color can persist much longer than in normally packaged meat. Typical levels of carbon monoxide used in the facilities that use this process are between 0.4% to 0.5%. The technology was first given "generally recognized as safe" (GRAS) status by the U.S. Food and Drug Administration (FDA) in 2002 for use as a secondary packaging system, and does not require labeling. In 2004, the FDA approved CO as primary packaging method, declaring that CO does not mask spoilage odor. The process is currently unauthorized in many other countries, including Japan, Singapore, and the European Union. Toxicity Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. The Centers for Disease Control and Prevention estimates that several thousand people go to hospital emergency rooms every year to be treated for carbon monoxide poisoning. According to the Florida Department of Health, "every year more than 500 Americans die from accidental exposure to carbon monoxide and thousands more across the U.S. require emergency medical care for non-fatal carbon monoxide poisoning." The American Association of Poison Control Centers (AAPCC) reported 15,769 cases of carbon monoxide poisoning resulting in 39 deaths in 2007. In 2005, the CPSC reported 94 generator-related carbon monoxide poisoning deaths. Carbon monoxide is colorless, odorless, and tasteless. As such, it's relatively undetectable. It readily combines with hemoglobin to produce carboxyhemoglobin which potentially affects gas exchange; therefore exposure can be highly toxic. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin. A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm. In addition to affecting oxygen delivery, carbon monoxide also binds to other hemoproteins such as myoglobin and mitochondrial cytochrome oxidase, metallic and non-metallic cellular targets to affect many cell operations. Weaponization In ancient history, Hannibal executed Roman prisoners with coal fumes during the Second Punic War. Carbon monoxide had been used for genocide during the Holocaust at some extermination camps, the most notable by gas vans in Chełmno, and in the Action T4 "euthanasia" program. Miscellaneous Lasers Carbon monoxide has also been used as a lasing medium in high-powered infrared lasers.

A context-sensitive grammar (CSG) is a formal grammar in which the left-hand sides and right-hand sides of any production rules may be surrounded by a context of terminal and nonterminal symbols. Context-sensitive grammars are more general than context-free grammars, in the sense that there are languages that can be described by CSG but not by context-free grammars. Context-sensitive grammars are less general (in the same sense) than unrestricted grammars. Thus, CSG are positioned between context-free and unrestricted grammars in the Chomsky hierarchy. A formal language that can be described by a context-sensitive grammar, or, equivalently, by a noncontracting grammar or a linear bounded automaton, is called a context-sensitive language. Some textbooks actually define CSGs as non-contracting, although this is not how Noam Chomsky defined them in 1959. This choice of definition makes no difference in terms of the languages generated (i.e. the two definitions are weakly equivalent), but it does make a difference in terms of what grammars are structurally considered context-sensitive; the latter issue was analyzed by Chomsky in 1963. Chomsky introduced context-sensitive grammars as a way to describe the syntax of natural language where it is often the case that a word may or may not be appropriate in a certain place depending on the context. Walter Savitch has criticized the terminology "context-sensitive" as misleading and proposed "non-erasing" as better explaining the distinction between a CSG and an unrestricted grammar. Although it is well known that certain features of languages (e.g. cross-serial dependency) are not context-free, it is an open question how much of CSG's expressive power is needed to capture the context sensitivity found in natural languages. Subsequent research in this area has focused on the more computationally tractable mildly context-sensitive languages. The syntaxes of some visual programming languages can be described by context-sensitive graph grammars. Formal definition A formal grammar G = (N, Σ, P, S), with N a set of nonterminal symbols, Σ a set of terminal symbols, P a set of production rules, and S the start symbol, is context-sensitive if all rules in P are of the form αAβ → αγβ with A ∈ N, α,β ∈ (N∪Σ)* and γ ∈ (N∪Σ)+. A string u ∈ (N∪Σ)* directly yields, or directly derives to, a string v ∈ (N∪Σ)*, denoted as u ⇒ v, if u can be written as lαAβr, and v can be written as lαγβr, for some production rule (αAβ→αγβ) ∈ P, and some context strings l, r ∈ (N∪Σ)*. More generally, u is said to yield, or derive to, v, denoted as u ⇒* v, if u = u1 ⇒ ... ⇒ un = v for some n≥0 and some strings u2, ..., un-1 (N∪Σ)*. That is, the relation (⇒*) is the reflexive transitive closure of the relation (⇒). The language of the grammar G is the set of all terminal symbol strings derivable from its start symbol, formally: L(G) = { w ∈ Σ*: S ⇒* w }. Derivations that do not end in a string composed of terminal symbols only are possible, but don't contribute to L(G). The only difference between this definition of Chomsky and that of unrestricted grammars is that γ can be empty in the unrestricted case. Some definitions of a context-sensitive grammar only require that for any production rule of the form u → v, the length of u shall be less than or equal to the length of v. This seemingly weaker requirement is in fact weakly equivalent, see Noncontracting grammar#Transforming into context-sensitive grammar. In addition, a rule of the form S → λ where λ represents the empty string and S does not appear on the right-hand side of any rule is permitted. The addition of the empty string allows the statement that the context sensitive languages are a proper superset of the context-free languages, rather than having to make the weaker statement that all context-free grammars with no →λ productions are also context sensitive grammars. The name context-sensitive is explained by the α and β that form the context of A and determine whether A can be replaced with γ or not. This is different from a context-free grammar where the context of a nonterminal is not taken into consideration. Indeed, every production of a context-free grammar is of the form V → w where V is a single nonterminal symbol, and w is a string of terminals and/or nonterminals; w can be empty. If the possibility of adding the empty string to a language is added to the strings recognized by the noncontracting grammars (which can never include the empty string) then the languages in these two definitions are identical. The left-context- and right-context-sensitive grammars are defined by restricting the rules to just the form αA → αγ and to just Aβ → γβ, respectively. The languages generated by these grammars are also the full class of context-sensitive languages. The equivalence was established by Penttonen normal form. Examples anbncn The following context-sensitive grammar, with start symbol S, generates the canonical non-context-free language { anbncn : n ≥ 1 } : Rules 1 and 2 allow for blowing-up S to anBC(BC)n-1; rules 3 to 6 allow for successively exchanging each CB to BC (four rules are needed for that since a rule CB → BC wouldn't fit into the scheme αAβ → αγβ); rules 7–10 allow replacing a non-terminals B and C with its corresponding terminals b and c respectively, provided it is in the right place. A generation chain for is: S →2 →2 →1 →3 →4 →5 →6 →3 →4 →5 →6 →3 →4 →5 →6 →7 →8 →8 →9 →10 →10 anbncndn, etc. More complicated grammars can be used to parse { anbncndn: n ≥ 1 }, and other languages with even more letters. Here we show a simpler approach using non-contracting grammars: Start with a kernel of regular productions generating the sentential forms and then include the non contracting productions , , , , , , , , , . ambncmdn A non contracting grammar (for which there is an equivalent ) for the language is defined by and , , , , , , . With these definitions, a derivation for is: . a2i A noncontracting grammar for the language { a2i : i ≥ 1 } is constructed in Example 9.5 (p. 224) of (Hopcroft, Ullman, 1979): Kuroda normal form Every context-sensitive grammar which does not generate the empty string can be transformed into a weakly equivalent one in Kuroda normal form. "Weakly equivalent" here means that the two grammars generate the same language. The normal form will not in general be context-sensitive, but will be a noncontracting grammar. The Kuroda normal form is an actual normal form for non-contracting grammars. Properties and uses Equivalence to linear bounded automaton A formal language can be described by a context-sensitive grammar if and only if it is accepted by some linear bounded automaton (LBA). In some textbooks this result is attributed solely to Landweber and Kuroda. Others call it the Myhill–Landweber–Kuroda theorem. (Myhill introduced the concept of deterministic LBA in 1960. Peter S. Landweber published in 1963 that the language accepted by a deterministic LBA is context sensitive. Kuroda introduced the notion of non-deterministic LBA and the equivalence between LBA and CSGs in 1964.) it is still an open question whether every context-sensitive language can be accepted by a deterministic LBA. Closure properties Context-sensitive languages are closed under complement. This 1988 result is known as the Immerman–Szelepcsényi theorem. Moreover, they are closed under union, intersection, concatenation, substitution, inverse homomorphism, and Kleene plus. Every recursively enumerable language L can be written as h(L) for some context-sensitive language L and some string homomorphism h. Computational problems The decision problem that asks whether a certain string s belongs to the language of a given context-sensitive grammar G, is PSPACE-complete. Moreover, there are context-sensitive grammars whose languages are PSPACE-complete. In other words, there is a context-sensitive grammar G such that deciding whether a certain string s belongs to the language of G is PSPACE-complete (so G is fixed and only s is part of the input of the problem). The emptiness problem for context-sensitive grammars (given a context-sensitive grammar G, is L(G)=∅ ?) is undecidable. As model of natural languages Savitch has proven the following theoretical result, on which he bases his criticism of CSGs as basis for natural language: for any recursively enumerable set R, there exists a context-sensitive language/grammar G which can be used as a sort of proxy to test membership in R in the following way: given a string s, s is in R if and only if there exists a positive integer n for which scn is in G, where c is an arbitrary symbol not part of R. It has been shown that nearly all natural languages may in general be characterized by context-sensitive grammars, but the whole class of CSG's seems to be much bigger than natural languages. Worse yet, since the aforementioned decision problem for CSG's is PSPACE-complete, that makes them totally unworkable for practical use, as a polynomial-time algorithm for a PSPACE-complete problem would imply P=NP. It was proven that some natural languages are not context-free, based on identifying so-called cross-serial dependencies and unbounded scrambling phenomena. However this does not necessarily imply that all the class CSG is necessary to capture "context sensitivity" in the colloquial sense of these terms in natural languages. For example, the strictly weaker (than CSG) linear context-free rewriting systems (LCFRS) can account for the phenomenon of cross-serial dependencies; one can write a LCFRS grammar for {anbncndn | n ≥ 1} for example. Ongoing research on computational linguistics has focused on formulating other classes of languages that are "mildly context-sensitive" whose decision problems are feasible, such as tree-adjoining grammars, combinatory categorial grammars, coupled context-free languages, and linear context-free rewriting systems. The languages generated by these formalisms properly lie between the context-free and context-sensitive languages. More recently, the class PTIME has been identified with range concatenation grammars, which are now considered to be the most expressive of the mild-context sensitive language classes.

The Casiquiare river () is a distributary of the upper Orinoco flowing southward into the Rio Negro, in Venezuela, South America. As such, it forms a unique natural canal between the Orinoco and Amazon river systems. It is the world's largest river of the kind that links two major river systems, a so-called bifurcation. The area forms a water divide, more dramatically at regional flood stage. Discovery In 1744 a Jesuit priest named Father Roman, while ascending the Orinoco River, met some Portuguese slave-traders from the settlements on the Rio Negro. He accompanied them on their return, by way of the Casiquiare canal, and afterwards retraced his route to the Orinoco. Charles Marie de La Condamine, seven months later, was able to give to the Académie française an account of Father Roman's voyage, and thus confirm the existence of this waterway, first reported by Father Acuña in 1639. Little credence was given to Father Roman's statement until it was verified, in 1756, by the Spanish Boundary-line Commission of José Yturriaga and Solano. In 1800 German scientist Alexander von Humboldt and French botanist Aimé Bonpland explored the river. During a 1924–25 expedition, Alexander H. Rice Jr. of Harvard University traveled up the Orinoco, traversed the Casiquiare canal, and descended the Rio Negro to the Amazon at Manaus. It was the first expedition to use aerial photography and shortwave radio for mapping of the region. In 1968 the Casiquiare was navigated by an SRN6 hovercraft during a National Geographic expedition. Geography The origin of the Casiquiare, at the River Orinoco, is below the mission of La Esmeralda at , and about above sea level. Its mouth at the Rio Negro, an affluent of the Amazon River, is near the town of San Carlos and is above sea level. The general course is south-west, and its length, including windings, is about . Its width, at its bifurcation with the Orinoco, is approximately , with a current towards the Rio Negro of . However, as it gains in volume from the very numerous tributary streams, large and small, that it receives en route, its velocity increases, and in the wet season reaches , even in certain stretches. It broadens considerably as it approaches its mouth, where it is about wide. The volume of water the Casiquiare captures from the Orinoco is small in comparison to what it accumulates in its course. Nevertheless, the geological processes are ongoing, and evidence points to a slow and gradual increase in the size of Casiquiare. It is likely that stream capture is in progress, i.e. what currently is the uppermost Orinoco basin, including Cunucunuma River, eventually will be entirely diverted by the Casiquiare into the Amazon basin. In flood time, it is said to have a second connection with the Rio Negro by a branch, which it throws off to the westward, called the Itinivini, which leaves it at a point about above its mouth. In the dry season, it has shallows, and is obstructed by sandbanks, a few rapids and granite rocks. Its shores are densely wooded, and the soil more fertile than that along the Rio Negro. The general slope of the plains through which the canal runs is south-west, but those of the Rio Negro slope south-east. The Casiquiare is not a sluggish canal on a flat tableland, but a great, rapid river which, if its upper waters had not found contact with the Orinoco, perhaps by cutting back, would belong entirely to the Negro branch of the Amazon. To the west of the Casiquiare, there is a much shorter and easier portage between the Orinoco and Amazon basins, called the isthmus of Pimichin, which is reached by ascending the Temi branch of the Atabapo River, an affluent of the Orinoco. Although the Temi is somewhat obstructed, it is believed that it could easily be made navigable for small craft. The isthmus is across, with undulating ground, nowhere over high, with swamps and marshes. It is much used for the transit of large canoes, which are hauled across it from the Temi river, and which reach the Rio Negro by the little stream called the Pimichin. Hydrographic divide The Casiquiare canal – Orinoco River hydrographic divide is a representation of the hydrographic water divide that delineates the separation between the Orinoco Basin and the Amazon Basin. (The Orinoco Basin flows west–north–northeast into the Caribbean; the Amazon Basin flows east into the western Atlantic in the extreme northeast of Brazil.) Essentially the river divide is a west-flowing, upriver section of Venezuela's Orinoco River with an outflow to the south into the Amazon Basin. This named outflow is the Casiquiare canal, which, as it heads downstream (southerly), picks up speed and also accumulates water volume. The greatest manifestation of the divide is during floods. During flood stage, the Casiquiare's main outflow point into the Rio Negro is supplemented by an overflow that is a second, and more minor, entry river bifurcation into the Rio Negro and upstream from its major, common low-water entry confluence with the Rio Negro. At flood, the river becomes an area flow source, far more than a narrow confined river. The Casiquiare canal connects the upper Orinoco, below the mission of Esmeraldas, with the Rio Negro affluent of the Amazon River near the town of San Carlos. The simplest description (besides the entire area-floodplain) of the water divide is a "south-bank Orinoco River strip" at the exit point of the Orinoco, also the origin of the Casiquiare canal. However, during the Orinoco's flood stage, that single, simply defined "origin of the canal" is turned into a region, and an entire strip along the southern bank of the Orinoco River.

In historical linguistics, cognates, also called lexical cognates, are sets of words in different languages that have been inherited in direct descent from an etymological ancestor in a common parent language. Because language change can have very radical effects on both the sound and the meaning of a word, cognates may not be obvious, and often it takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate or not. The term cognate derives from the Latin noun cognatus, which means "blood relative". Characteristics Cognates do not need to have the same meaning, which may have changed as the languages developed separately. For example English starve and Dutch sterven or German sterben ("to die") all derive from the same Proto-Germanic root, *sterbaną ("die"). Also, cognates do not need to have similar forms: English father, French père, and Armenian հայր (hayr) all descend directly from Proto-Indo-European *ph₂tḗr. An extreme case is Armenian երկու (erku) and English two, which descend from Proto-Indo-European *dwóh₁ (note that the sound change *dw > erk in Armenian is regular). An example of cognates in Indo-European languages are the words night (English), nicht (Scots), Nacht (German), nacht (Dutch, Frisian), nag (Afrikaans), Naach (Colognian), natt (Swedish, Norwegian), nat (Danish), nátt (Faroese), nótt (Icelandic), noc (Czech, Slovak, Polish), ночь, noch (Russian), ноќ, noć (Macedonian), нощ, nosht (Bulgarian), nishi (Bengali), ніч, nich (Ukrainian), ноч, noch/noč (Belarusian), noč (Slovene), noć (Serbo-Croatian), nakts (Latvian), naktis (Lithuanian), νύξ, nyx (Ancient Greek), νύχτα / nychta (Modern Greek), nakt- (Sanskrit), natë (Albanian), nos (Welsh, Cornish), noz (Breton), nox/nocte (Latin), nuit (French), noche (Spanish), nueche (Asturian), noite (Portuguese and Galician), notte (Italian), nit (Catalan), nuet/nit/nueit (Aragonese), nuèch / nuèit (Occitan) and noapte (Romanian), all meaning "night" and being derived from the Proto-Indo-European "night". The Indo-European languages have many hundreds of such sets of cognates, though not all are as neat as the cognates of night. The Arabic salām, the Hebrew shalom, the Assyrian Neo-Aramaic shlama and the Amharic selam ("peace") are also cognates, derived from the Proto-Semitic *šalām- "peace". Cognates may often be less easily recognised than the above examples, and authorities sometimes differ in their interpretations of the evidence. The English word milk is clearly a cognate of German Milch, Dutch and Afrikaans melk, Russian молоко (moloko), Serbo-Croatian and Slovenian mleko/mlijeko. On the other hand, French lait, Catalan llet, Italian latte, Romanian lapte, Spanish leche and leite (Portuguese and Galician) (all meaning "milk") are less-obvious cognates of Ancient Greek gálaktos (genitive singular of gála, "milk"), a relationship that is more evidently seen through the intermediate Latin lac "milk" as well as the English word lactic and other terms borrowed from Latin. Some cognates are semantic opposites. For instance, while the Hebrew word chutzpah means "impudence", its Classical Arabic cognate ḥaṣāfah means "sound judgment." False cognates False cognates are words that are believed to have a common origin, but which in fact do not. For example, Latin and German both mean 'to have' and are phonetically similar. However, the words evolved from different Proto-Indo-European (PIE) roots: , like English have, comes from PIE *kh₂pyé- 'to grasp', and has the Latin cognate capere 'to seize, grasp, capture'. , on the other hand, is from PIE *gʰabʰ 'to give, to receive', and hence cognate with English give and German . Likewise, English much and Spanish look similar and have a similar meaning, but are not cognates: much is from Proto-Germanic *mikilaz < PIE *meǵ- and is from Latin multum < PIE *mel-; a true cognate is Spanish 'big' (archaic). Distinctions Cognates are distinguished from other kinds of relationships. Loanwords are words borrowed from one language into another, for example English beef is borrowed from Old French boef (meaning "ox"). Although they are part of a single etymological stemma, linguists do not normally call them cognates. Doublets are pairs of words in the same language which are derived from a single etymon, which may have similar but distinct meanings and uses. Often one is a loanword and the other is the native form, or they have developed in different dialects and then found themselves together in a modern standard language. For example, Old French boef is cognate with English cow, so English cow and beef are doublets. Equivalents or translations are words in two different languages that have similar meanings. They may be cognate, but usually they are not. For example, the German equivalent of the English word cow is Kuh, which is also cognate, but the French equivalent is vache, which is unrelated.

Corona Borealis is a small constellation in the Northern Celestial Hemisphere. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Its brightest stars form a semicircular arc. Its Latin name, inspired by its shape, means "northern crown". In classical mythology Corona Borealis generally represented the crown given by the god Dionysus to the Cretan princess Ariadne and set by her in the heavens. Other cultures likened the pattern to a circle of elders, an eagle's nest, a bear's den, or even a smokehole. Ptolemy also listed a southern counterpart, Corona Australis, with a similar pattern. The brightest star is the magnitude 2.2 Alpha Coronae Borealis. The yellow supergiant R Coronae Borealis is the prototype of a rare class of giant stars—the R Coronae Borealis variables—that are extremely hydrogen deficient, and thought to result from the merger of two white dwarfs. T Coronae Borealis, also known as the Blaze Star, is another unusual type of variable star known as a recurrent nova. Normally of magnitude 10, it last flared up to magnitude 2 in 1946. ADS 9731 and Sigma Coronae Borealis are multiple star systems with six and five components respectively. Five star systems have been found to have Jupiter-sized exoplanets. Abell 2065 is a highly concentrated galaxy cluster one billion light-years from the Solar System containing more than 400 members, and is itself part of the larger Corona Borealis Supercluster. Characteristics Covering 179 square degrees and hence 0.433% of the sky, Corona Borealis ranks 73rd of the 88 modern constellations by area. Its position in the Northern Celestial Hemisphere means that the whole constellation is visible to observers north of 50°S. It is bordered by Boötes to the north and west, Serpens Caput to the south, and Hercules to the east. The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "CrB". The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon of eight segments (illustrated in infobox). In the equatorial coordinate system, the right ascension coordinates of these borders lie between and , while the declination coordinates are between 39.71° and 25.54°. It has a counterpart—Corona Australis—in the Southern Celestial Hemisphere. Features Stars The seven stars that make up the constellation's distinctive crown-shaped pattern are all 4th-magnitude stars except for the brightest of them, Alpha Coronae Borealis. The other six stars are Theta, Beta, Gamma, Delta, Epsilon and Iota Coronae Borealis. The German cartographer Johann Bayer gave twenty stars in Corona Borealis Bayer designations from Alpha to Upsilon in his 1603 star atlas Uranometria. Zeta Coronae Borealis was noted to be a double star by later astronomers and its components designated Zeta1 and Zeta2. John Flamsteed did likewise with Nu Coronae Borealis; classed by Bayer as a single star, it was noted to be two close stars by Flamsteed. He named them 20 and 21 Coronae Borealis in his catalogue, alongside the designations Nu1 and Nu2 respectively. Chinese astronomers deemed nine stars to make up the asterism, adding Pi and Rho Coronae Borealis. Within the constellation's borders, there are 37 stars brighter than or equal to apparent magnitude 6.5. Alpha Coronae Borealis (officially named Alphecca by the IAU, but sometimes also known as Gemma) appears as a blue-white star of magnitude 2.2. In fact, it is an Algol-type eclipsing binary that varies by 0.1 magnitude with a period of 17.4 days. The primary is a white main-sequence star of spectral type A0V that is 2.91 times the mass of the Sun () and 57 times as luminous (), and is surrounded by a debris disk out to a radius of around 60 astronomical units (AU). The secondary companion is a yellow main-sequence star of spectral type G5V that is a little smaller (0.9 times) the diameter of the Sun. Lying 75±0.5 light-years from Earth, Alphecca is believed to be a member of the Ursa Major Moving Group of stars that have a common motion through space. Located 112±3 light-years away, Beta Coronae Borealis or Nusakan is a spectroscopic binary system whose two components are separated by 10 AU and orbit each other every 10.5 years. The brighter component is a rapidly oscillating Ap star, pulsating with a period of 16.2 minutes. Of spectral type A5V with a surface temperature of around 7980 K, it has around , 2.6 solar radii (), and . The smaller star is of spectral type F2V with a surface temperature of around 6750 K, and has around , , and between 4 and . Near Nusakan is Theta Coronae Borealis, a binary system that shines with a combined magnitude of 4.13 located 380±20 light-years distant. The brighter component, Theta Coronae Borealis A, is a blue-white star that spins extremely rapidly—at a rate of around 393 km per second. A Be star, it is surrounded by a debris disk. Flanking Alpha to the east is Gamma Coronae Borealis, yet another binary star system, whose components orbit each other every 92.94 years and are roughly as far apart from each other as the Sun and Neptune. The brighter component has been classed as a Delta Scuti variable star, though this view is not universal. The components are main sequence stars of spectral types B9V and A3V. Located 170±2 light-years away, 4.06-magnitude Delta Coronae Borealis is a yellow giant star of spectral type G3.5III that is around and has swollen to . It has a surface temperature of 5180 K. For most of its existence, Delta Coronae Borealis was a blue-white main-sequence star of spectral type B before it ran out of hydrogen fuel in its core. Its luminosity and spectrum suggest it has just crossed the Hertzsprung gap, having finished burning core hydrogen and just begun burning hydrogen in a shell that surrounds the core. Zeta Coronae Borealis is a double star with two blue-white components 6.3 arcseconds apart that can be readily separated at 100x magnification. The primary is of magnitude 5.1 and the secondary is of magnitude 6.0. Nu Coronae Borealis is an optical double, whose components are a similar distance from Earth but have different radial velocities, hence are assumed to be unrelated. The primary, Nu1 Coronae Borealis, is a red giant of spectral type M2III and magnitude 5.2, lying 640±30 light-years distant, and the secondary, Nu2 Coronae Borealis, is an orange-hued giant star of spectral type K5III and magnitude 5.4, estimated to be 590±30 light-years away. Sigma Coronae Borealis, on the other hand, is a true multiple star system divisible by small amateur telescopes. It is actually a complex system composed of two stars around as massive as the Sun that orbit each other every 1.14 days, orbited by a third Sun-like star every 726 years. The fourth and fifth components are a binary red dwarf system that is 14,000 AU distant from the other three stars. ADS 9731 is an even rarer multiple system in the constellation, composed of six stars, two of which are spectroscopic binaries. Corona Borealis is home to two remarkable variable stars. T Coronae Borealis is a cataclysmic variable star also known as the Blaze Star. Normally placid around magnitude 10—it has a minimum of 10.2 and maximum of 9.9—it brightens to magnitude 2 in a period of hours, caused by a nuclear chain reaction and the subsequent explosion. T Coronae Borealis is one of a handful of stars called recurrent novae, which include T Pyxidis and U Scorpii. An outburst of T Coronae Borealis was first recorded in 1866; its second recorded outburst was in February 1946. T Coronae Borealis is a binary star with a red-hued giant primary and a white dwarf secondary, the two stars orbiting each other over a period of approximately 8 months. R Coronae Borealis is a yellow-hued variable supergiant star, over 7000 light-years from Earth, and prototype of a class of stars known as R Coronae Borealis variables. Normally of magnitude 6, its brightness periodically drops as low as magnitude 15 and then slowly increases over the next several months. These declines in magnitude come about as dust that has been ejected from the star obscures it. Direct imaging with the Hubble Space Telescope shows extensive dust clouds out to a radius of around 2000 AU from the star, corresponding with a stream of fine dust (composed of grains 5 nm in diameter) associated with the star's stellar wind and coarser dust (composed of grains with a diameter of around 0.14 µm) ejected periodically. There are several other variables of reasonable brightness for amateur astronomer to observe, including three Mira-type long period variables: S Coronae Borealis ranges between magnitudes 5.8 and 14.1 over a period of 360 days. Located around 1946 light-years distant, it shines with a luminosity 16,643 times that of the Sun and has a surface temperature of 3033 K. One of the reddest stars in the sky, V Coronae Borealis is a cool star with a surface temperature of 2877 K that shines with a luminosity 102,831 times that of the Sun and is a remote 8810 light-years distant from Earth. Varying between magnitudes 6.9 and 12.6 over a period of 357 days, it is located near the junction of the border of Corona Borealis with Hercules and Bootes. Located 1.5° northeast of Tau Coronae Borealis, W Coronae Borealis ranges between magnitudes 7.8 and 14.3 over a period of 238 days. Another red giant, RR Coronae Borealis is a M3-type semiregular variable star that varies between magnitudes 7.3 and 8.2 over 60.8 days. RS Coronae Borealis is yet another semiregular variable red giant, which ranges between magnitudes 8.7 to 11.6 over 332 days. It is unusual in that it is a red star with a high proper motion (greater than 50 milliarcseconds a year). Meanwhile, U Coronae Borealis is an Algol-type eclipsing binary star system whose magnitude varies between 7.66 and 8.79 over a period of 3.45 days TY Coronae Borealis is a pulsating white dwarf (of ZZ Ceti) type, which is around 70% as massive as the Sun, yet has only 1.1% of its diameter. Discovered in 1990, UW Coronae Borealis is a low-mass X-ray binary system composed of a star less massive than the Sun and a neutron star surrounded by an accretion disk that draws material from the companion star. It varies in brightness in an unusually complex manner: the two stars orbit each other every 111 minutes, yet there is another cycle of 112.6 minutes, which corresponds to the orbit of the disk around the degenerate star. The beat period of 5.5 days indicates the time the accretion disk—which is asymmetrical—takes to precess around the star. Extrasolar planetary systems Extrasolar planets have been confirmed in five star systems, four of which were found by the radial velocity method. The spectrum of Epsilon Coronae Borealis was analysed for seven years from 2005 to 2012, revealing a planet around 6.7 times as massive as Jupiter () orbiting every 418 days at an average distance of around 1.3 AU. Epsilon itself is a orange giant of spectral type K2III that has swollen to and . Kappa Coronae Borealis is a spectral type K1IV orange subgiant nearly twice as massive as the Sun; around it lie a dust debris disk, and one planet with a period of 3.4 years. This planet's mass is estimated at . The dimensions of the debris disk indicate it is likely there is a second substellar companion. Omicron Coronae Borealis is a K-type clump giant with one confirmed planet with a mass of that orbits every 187 days—one of the two least massive planets known around clump giants. HD 145457 is an orange giant of spectral type K0III found to have one planet of . Discovered by the Doppler method in 2010, it takes 176 days to complete an orbit. XO-1 is a magnitude 11 yellow main-sequence star located approximately light-years away, of spectral type G1V with a mass and radius similar to the Sun. In 2006 the hot Jupiter exoplanet XO-1b was discovered orbiting XO-1 by the transit method using the XO Telescope. Roughly the size of Jupiter, it completes an orbit around its star every three days. The discovery of a Jupiter-sized planetary companion was announced in 1997 via analysis of the radial velocity of Rho Coronae Borealis, a yellow main sequence star and Solar analog of spectral type G0V, around 57 light-years distant from Earth. More accurate measurement of data from the Hipparcos satellite subsequently showed it instead to be a low-mass star somewhere between 100 and 200 times the mass of Jupiter. Possible stable planetary orbits in the habitable zone were calculated for the binary star Eta Coronae Borealis, which is composed of two stars—yellow main sequence stars of spectral type G1V and G3V respectively—similar in mass and spectrum to the Sun. No planet has been found, but a brown dwarf companion about 63 times as massive as Jupiter with a spectral type of L8 was discovered at a distance of 3640 AU from the pair in 2001. Deep-sky objects Corona Borealis contains few galaxies observable with amateur telescopes. NGC 6085 and 6086 are a faint spiral and elliptical galaxy respectively close enough to each other to be seen in the same visual field through a telescope. Abell 2142 is a huge (six million light-year diameter), X-ray luminous galaxy cluster that is the result of an ongoing merger between two galaxy clusters. It has a redshift of 0.0909 (meaning it is moving away from us at 27,250 km/s) and a visual magnitude of 16.0. It is about 1.2 billion light-years away. Another galaxy cluster in the constellation, RX J1532.9+3021, is approximately 3.9 billion light-years from Earth. At the cluster's center is a large elliptical galaxy containing one of the most massive and most powerful supermassive black holes yet discovered. Abell 2065 is a highly concentrated galaxy cluster containing more than 400 members, the brightest of which are 16th magnitude; the cluster is more than one billion light-years from Earth. On a larger scale still, Abell 2065, along with Abell 2061, Abell 2067, Abell 2079, Abell 2089, and Abell 2092, make up the Corona Borealis Supercluster. Another galaxy cluster, Abell 2162, is a member of the Hercules Superclusters. Mythology In Greek mythology, Corona Borealis was linked to the legend of Theseus and the minotaur. It was generally considered to represent a crown given by Dionysus to Ariadne, the daughter of Minos of Crete, after she had been abandoned by the Athenian prince Theseus. When she wore the crown at her marriage to Dionysus, he placed it in the heavens to commemorate their wedding. An alternate version has the besotted Dionysus give the crown to Ariadne, who in turn gives it to Theseus after he arrives in Crete to kill the minotaur that the Cretans have demanded tribute from Athens to feed. The hero uses the crown's light to escape the labyrinth after disposing of the creature, and Dionysus later sets it in the heavens. The Latin author Hyginus linked it to a crown or wreath worn by Bacchus (Dionysus) to disguise his appearance when first approaching Mount Olympus and revealing himself to the gods, having been previously hidden as yet another child of Jupiter's trysts with a mortal, in this case Semele. Corona Borealis was one of the 48 constellations mentioned in the Almagest of classical astronomer Ptolemy. In Mesopotamia, Corona Borealis was associated with the goddess Nanaya. In Welsh mythology, it was called Caer Arianrhod, "the Castle of the Silver Circle", and was the heavenly abode of the Lady Arianrhod. To the ancient Balts, Corona Borealis was known as Darželis, the "flower garden." The Arabs called the constellation Alphecca (a name later given to Alpha Coronae Borealis), which means "separated" or "broken up" ( ), a reference to the resemblance of the stars of Corona Borealis to a loose string of jewels. This was also interpreted as a broken dish. Among the Bedouins, the constellation was known as (), or "the dish/bowl of the poor people". The Skidi people of Native Americans saw the stars of Corona Borealis representing a council of stars whose chief was Polaris. The constellation also symbolised the smokehole over a fireplace, which conveyed their messages to the gods, as well as how chiefs should come together to consider matters of importance. The Shawnee people saw the stars as the Heavenly Sisters, who descended from the sky every night to dance on earth. Alphecca signifies the youngest and most comely sister, who was seized by a hunter who transformed into a field mouse to get close to her. They married though she later returned to the sky, with her heartbroken husband and son following later. The Mi'kmaq of eastern Canada saw Corona Borealis as Mskegwǒm, the den of the celestial bear (Alpha, Beta, Gamma and Delta Ursae Majoris). Polynesian peoples often recognized Corona Borealis; the people of the Tuamotus named it Na Kaua-ki-tokerau and probably Te Hetu. The constellation was likely called Kaua-mea in Hawaii, Rangawhenua in New Zealand, and Te Wale-o-Awitu in the Cook Islands atoll of Pukapuka. Its name in Tonga was uncertain; it was either called Ao-o-Uvea or Kau-kupenga. In Australian Aboriginal astronomy, the constellation is called womera ("the boomerang") due to the shape of the stars. The Wailwun people of northwestern New South Wales saw Corona Borealis as mullion wollai "eagle's nest", with Altair and Vega—each called mullion—the pair of eagles accompanying it. The Wardaman people of northern Australia held the constellation to be a gathering point for Men's Law, Women's Law and Law of both sexes come together and consider matters of existence. Later references Corona Borealis was renamed Corona Firmiana in honour of the Archbishop of Salzburg in the 1730 Atlas Mercurii Philosophicii Firmamentum Firminianum Descriptionem by Corbinianus Thomas, but this was not taken up by subsequent cartographers. The constellation was featured as a main plot ingredient in the short story "Hypnos" by H. P. Lovecraft, published in 1923; it is the object of fear of one of the protagonists in the short story. Finnish band Cadacross released an album titled Corona Borealis in 2002.

The Country Liberal Party (CLP), officially the Country Liberals (Northern Territory), is a liberal conservative political party in Australia founded in 1974, which operates solely in the Northern Territory, however due to Christmas Island and the Cocos (Keeling) Islands forming part of the Division of Lingiari they also vote for the Country Liberal Party. The CLP first fielded candidates at the 1975 federal election, winning one seat in the Senate and the non-voting seat in the House of Representatives. Since 1979, the CLP has been formally affiliated with both the federal Liberal Party of Australia and the National Party of Australia (previously the Country Party and National Country Party), the two partners in the federal Coalition. The CLP has full voting rights within the National Party and observer status with the Liberal Party. Currently, the CLP has one representative in federal parliament, Senator Sam McMahon, who sits with the parliamentary National Party. The CLP dominated the Northern Territory Legislative Assembly from its establishment in 1974 until the 2001 general election, when the CLP lost government winning only 10 of the 25 seats, and was reduced further to four parliamentary members at the 2005 election. At the 2008 election it increased its numbers, winning 11 seats. The CLP returned to office following the 2012 election, winning 16 of 25 seats, and leader Terry Mills became Chief Minister of the Northern Territory. Less than a year later, Mills was replaced as Chief Minister and CLP leader by Adam Giles at the 2013 CLP leadership ballot on 13 March. Giles was the first indigenous Australian to lead a state or territory government in Australia. Giles was defeated at the 2015 CLP leadership ballot but managed to survive in the aftermath. Multiple defections saw the CLP reduced to minority government a few months later. At the 27 August 2016 Territory election, the CLP was resoundingly defeated, winning just two of 25 seats. Gary Higgins became CLP leader and opposition leader on 2 September, with Lia Finocchiaro as his deputy. On 20 January 2020, Higgins stood down as party leader and announced his retirement at the next election. Finocchiaro became CLP leader and leader of the opposition on 1 February 2020. History Origins A party system did not develop in the Northern Territory until the 1960s, due to its small population and lack of regular elections. The Australian Labor Party (ALP) contested elections as early as 1905, but rarely faced an organised opposition; anti-Labor candidates usually stood as independents. The regionalist North Australia Party (NAP), established by Lionel Rose for the Legislative Council elections in 1965, has been cited as a predecessor of the CLP. A Darwin branch of the Country Party was established on 20 July 1966, following by an Alice Springs branch on 29 July. The creation of the branches was spurred by the upcoming 1966 federal election and the announcement by the Northern Territory's federal MP Jock Nelson that he would be retiring from politics. The Country Party achieved its first electoral success with the election of Sam Calder as Nelson's replacement. It subsequently won four out of eleven seats at the 1968 Legislative Council elections. A third branch of the party was established in Katherine in February 1971. The branches affiliated with the Federal Council of the Australian Country Party in July 1971, establishing a formal entity with a central council, executive and annual conference. The party was formally named the "Australian Country Party – Northern Territory". The Country Party primarily drew its support from Alice Springs, small towns, and the pastoral industry, including "a fair proportion of the non-urban Aboriginal vote". The party did not have a strong presence in Darwin. A branch of the Liberal Party, the Country Party's coalition partner at a federal level, had been established in Darwin in 1966, representing commercial interests and urban professionals. The Liberals fielded candidates at the 1968 Legislative Council elections, but by 1970 the local branch had ceased to function. In 1973, the Country Party began actively working to include Liberal supporters within its organisation, spurred by the Whitlam Government's announcement of a fully elective Northern Territory Legislative Assembly. Following informal negotiations led by Goff Letts, a joint committee was established to determine changes to the Country Party's constitution and policy. These were officially approved, along with the adoption of the name Country Liberal Party, at the party's annual conference in Alice Springs on 20 July 1974. 1974–2001: Foundation and early dominance The Whitlam Government passed legislation in 1974 to establish a fully elected unicameral Northern Territory Legislative Assembly, replacing the previous partly elected Legislative Council, which had been in existence since 1947. The CLP won 17 out of 19 seats at the inaugural elections in October 1974, with independents holding the other two seats. Goff Letts became the inaugural majority leader, a title changed to chief minister after the granting of self-government in 1978. The CLP governed the Northern Territory from 1974 until the 2001 election. During this time, it never faced more than nine opposition members. Indeed, the CLP's dominance was so absolute that its internal politics were seen as a bigger threat than any opposition party. This was especially pronounced in the mid-1980s, when a series of party-room coups resulted in the Territory having three Chief Ministers in four years and also saw the creation of the Northern Territory Nationals as a short-lived splinter group under the leadership of former CLP chief minister Ian Tuxworth. The Whitlam Government also passed legislation to give the Northern Territory and Australian Capital Territory (ACT) representation in the federal Senate, with each territory electing two senators. Bernie Kilgariff was elected as the CLP's first senator at the 1975 federal election, sitting alongside Sam Calder in the parliamentary National Country Party. On 3 February 1979 a special conference of the CLP resolved that "the Federal CLP Parliamentarians be permitted to sit in the Party Rooms of their choice in Canberra". Despite personal misgivings, Kilgariff chose to sit with the parliamentary Liberal Party from 8 March 1979 in order that the CLP have representation in both parties, a practice which has been maintained where possible. 2001–2012: In opposition At the 2001 election the Australian Labor Party won government by one seat, ending 27 years of CLP government. The loss marked a major turning point in Northern Territory politics, a result which was exacerbated when, at the 2005 election, the ALP won the second-largest majority government in the history of the Territory, reducing the once-dominant party to just four members in the Legislative Assembly. This result was only outdone by the 1974 election, in which the CLP faced only two independents as opposition. The CLP even lost two seats in Palmerston, an area where the ALP had never come close to winning any seats before. In the 2001 federal election, the CLP won the newly formed seat of Solomon, based on Darwin/Palmerston, in the House of Representatives. In the 2004 federal election, the CLP held one seat in the House of Representatives, and one seat in the Senate. The CLP lost its federal lower house seat in the 2007 federal election, but regained it when Palmerston deputy mayor Natasha Griggs won back Solomon for the CLP. She sat with the Liberals in the House. The 2008 election saw the CLP recover from the severe loss it suffered three years earlier, increasing its representation from four to 11 members. Following the 2011 decision of ALP-turned-independent member Alison Anderson to join the CLP, this increased CLP's representation to 12 in the Assembly, leaving the incumbent Henderson Government to govern in minority with the support of Independent MP Gerry Wood. Historically, the CLP has been particularly dominant in the Territory's two major cities, Darwin/Palmerston and Alice Springs. However, in recent years the ALP has pulled even with the CLP in the Darwin area; indeed, its 2001 victory was fueled by an unexpected swing in Darwin. 2012–2016: Return to government and internal conflict The CLP under the leadership of Terry Mills returned to power in the 2012 election with 16 of 25 seats, defeating the incumbent Labor Government led by Paul Henderson. In the lead up to the Territory election, CLP Senator Nigel Scullion sharply criticised the Federal Labor Government for its suspension of the live cattle trade to Indonesia - an economic mainstay of the territory. The election victory ended 11 years of ALP rule in the Northern Territory. The victory was also notable for the support it achieved from indigenous people in pastoral and remote electorates. Large swings were achieved in remote Territory electorates (where the indigenous population comprised around two-thirds of voters) and a total of five Aboriginal CLP candidates won election to the Assembly. Among the indigenous candidates elected were high-profile Aboriginal activist Bess Price and former ALP member Alison Anderson. Anderson was appointed Minister for Indigenous Advancement. In a nationally reported speech in November 2012, Anderson condemned welfare dependency and a culture of entitlement in her first ministerial statement on the status of Aboriginal communities in the Territory and said the CLP would focus on improving education and on helping create real jobs for indigenous people. Leadership spills Adam Giles replaced Mills as Chief Minister of the Northern Territory and party leader at the 2013 CLP leadership ballot on 13 March while Mills was on a trade mission in Japan. Giles was sworn in as Chief Minister on 14 March, becoming the first indigenous head of government of an Australian state or territory. Willem Westra van Holthe challenged Giles at the 2015 CLP leadership ballot on 2 February and was elected leader by the party room in a late night vote conducted by phone. However, Giles refused to resign as Chief Minister following the vote. On 3 February, ABC News reported that officials were preparing an instrument for Giles' removal by the Administrator. The swearing-in of Westra van Holthe, which had been scheduled for 11:00 local time (01:30 UTC), was delayed. After a meeting of the parliamentary wing of the CLP, Giles announced that he would remain as party leader and Chief Minister, and that Westra van Holthe would be his deputy. Defections and minority government After four defections during the parliamentary term, the CLP was reduced to minority government by July 2015. Giles raised the possibility of an early election on 20 July stating that he would "love" to call a snap poll, but that it was "pretty much impossible to do". Crossbenchers dismissed the notion of voting against a confidence motion to bring down the government. 2016–present: In opposition Territory government legislation passed in February 2016 changed the voting method of single-member electorates from full-preferential voting to optional preferential voting ahead of the 2016 territory election held on 27 August. Federally, a MediaReach seat-level opinion poll of 513 voters in the seat of Solomon conducted 22−23 June ahead of the 2016 federal election held on 2 July surprisingly found Labor candidate Luke Gosling heavily leading two-term CLP incumbent Natasha Griggs 61–39 on the two-party vote from a large 12.4 percent swing. The CLP lost Solomon to Labor at the election, with Gosling defeating Griggs 56–44 on the two-party vote from a 7.4 percent swing. Polling ahead of the 2016 Territory election indicated a large swing against the CLP, including a near-total collapse in Darwin/Palmerston. By the time the writs were dropped, commentators had almost universally written off the CLP. At 27 August Territory election, the CLP was swept from power in a massive Labor landslide, suffering easily the worst defeat of a sitting government in Territory history and one of the worst defeats a governing party has ever suffered at the state or territory level in Australia. The party not only lost all of the bush seats it picked up in 2012, but was all but shut out of Darwin/Palmerston, winning only one seat there. All told, the CLP only won two seats, easily its worst showing in an election. Giles himself lost his own seat, becoming the second Majority Leader/Chief Minister to lose his own seat. Even before Giles' defeat was confirmed, second-term MP Gary Higgins—the only surviving member of the Giles cabinet—was named the party's new leader, with Lia Finocchiaro as his deputy. On 20 January 2020, Higgins announced his resignation as party leader and announced his retirement at the next election. Finocchiaro succeeded him as CLP leader and leader of the opposition on 1 February 2020. Finocchiaro led the CLP to a modest recovery at the 2020 Territory election. The CLP picked up a six-seat swing, boosting its seat count to eight. However, it failed to make significant inroads in Darwin/Palmerston, winning only two seats there, including that of Finocchiaro. The CLP lost the seat of Daly to Labor in a 2021 by-election, the first time an incumbent government had won a seat from the opposition in territory history. In January 2022, Sam McMahon resigned from the party, and will remain as an Independent for the remainder of her term, effectively causing the party to lose its representation in the senate with the loss of the one seat held by McMahon. Ideology The CLP stands for office in the Northern Territory Assembly and Federal Parliament of Australia and primarily concerns itself with representing Territory interests. It is a regionally based party, that has parliamentary representation in both the Federal Parliament and at the Territory level. It brands as a party with strong roots in the Territory. The CLP competes against the Australian Labor Party (Northern Territory Branch) (the local branch of Australia's social-democratic party). It is closely affiliated with, but is independent from the Liberal Party of Australia (a mainly urban, pro-business party comprising mainly liberal membership) and the National Party of Australia (a conservative agrarian and regional interests party). The party promotes traditional Liberal Party values such as individualism and private enterprise, and what it describes as "progressive" political policy such as full statehood for the Northern Territory. Organisation Branch delegates and members of the party's Central Council attend the Annual Conference of the Country Liberal Party to decide the party's platform. The Central Council is composed of the party's office bearers, its leaders from the Territory Assembly and the Federal Parliament and representatives of party branches. The Annual Conference of the Country Liberal Party, attended by branch delegates and members of the party's Central Council, decides matters relating to the party's platform and philosophy. The Central Council administers the party and makes decisions on pre-selections. It is composed of the party's office bearers, its leaders in the Northern Territory Legislative Assembly, members in the Federal Parliament, and representation from each of the party's branches. The CLP president has full voting rights with the National Party and observer status with the Liberal Party. Both the Liberals and Nationals receive Country Liberal delegations at their conventions. After federal elections, the CLP directs its federal members and senators as to which of the two other parties they should sit with in the parliamentary chamber. In practice, CLP House members usually sit with the Liberals, while CLP Senators sit with the Nationals.

A control store is the part of a CPU's control unit that stores the CPU's microprogram. It is usually accessed by a microsequencer. A control store implementation whose contents are unalterable is known as a Read Only Memory (ROM) or Read Only Storage (ROS); one whose contents are alterable is known as a Writable Control Store (WCS). Implementation Early use Early control stores were implemented as a diode-array accessed via address decoders, a form of read-only memory. This tradition dates back to the program timing matrix on the MIT Whirlwind, first described in 1947. Modern VLSI processors instead use matrices of field-effect transistors to build the ROM and/or PLA structures used to control the processor as well as its internal sequencer in a microcoded implementation. IBM System/360 used a variety of techniques: CCROS (Card Capacitor Read-Only Storage) on the Model 30, TROS (Transformer Read-Only Storage) on the Model 40, and BCROS (Balanced Capacitor Read-Only Storage) on Models 50, 65 and 67. Writable stores Some computers were built using "writable microcode" — rather than storing the microcode in ROM or hard-wired logic, the microcode was stored in a RAM called a writable control store or WCS. Such a computer is sometimes called a Writable Instruction Set Computer or WISC. Many of these machines were experimental laboratory prototypes, such as the WISC CPU/16 and the RTX 32P. The original System/360 models had read-only control store, but later System/360, System/370 and successor models loaded part or all of their microprograms from floppy disks or other DASD into a writable control store consisting of ultra-high speed random-access read-write memory. The System/370 architecture included a facility called Initial-Microprogram Load (IML or IMPL) that could be invoked from the console, as part of Power On Reset (POR) or from another processor in a tightly coupled multiprocessor complex. This permitted IBM to easily repair microprogramming defects in the field. Even when the majority of the control store is stored in ROM, computer vendors would often sell writable control store as an option, allowing the customers to customize the machine's microprogram. Other vendors, e.g., IBM, use the WCS to run microcode for emulator features and hardware diagnostics. Other commercial machines that used writable microcode include the Burroughs Small Systems (1970s and 1980s), the Xerox processors in their Lisp machines and Xerox Star workstations, the DEC VAX 8800 ("Nautilus") family, and the Symbolics L- and G-machines (1980s). Some DEC PDP-10 machines stored their microcode in SRAM chips (about 80 bits wide x 2 Kwords), which was typically loaded on power-on through some other front-end CPU. Many more machines offered user-programmable writable control stores as an option (including the HP 2100, DEC PDP-11/60 and Varian Data Machines V-70 series minicomputers). The Mentec M11 and Mentec M1 stored its microcode in SRAM chips, loaded on power-on through another CPU. The Data General Eclipse MV/8000 ("Eagle") had a SRAM writable control store, loaded on power-on through another CPU. WCS offered several advantages including the ease of patching the microprogram and, for certain hardware generations, faster access than ROMs could provide. User-programmable WCS allowed the user to optimize the machine for specific purposes. Some CPU designs compile the instruction set to a writable RAM or FLASH inside the CPU (such as the Rekursiv processor and the Imsys Cjip), or an FPGA (reconfigurable computing). Several Intel CPUs in the x86 architecture family have writable microcode, starting with the Pentium Pro in 1995. This has allowed bugs in the Intel Core 2 microcode and Intel Xeon microcode to be fixed in software, rather than requiring the entire chip to be replaced. Such fixes can be installed by Linux, FreeBSD, Microsoft Windows, or the motherboard BIOS. Timing, latching and avoiding a race condition The control store usually has a register on its outputs. The outputs that go back into the sequencer to determine the next address have to go through some sort of register to prevent the creation of a race condition. In most designs all of the other bits also go through a register. This is because the machine will work faster if the execution of the next microinstruction is delayed by one cycle. This register is known as a pipeline register. Very often the execution of the next microinstruction is dependent on the result of the current microinstruction, which will not be stable until the end of the current microcycle. It can be seen that either way, all of the outputs of the control store go into one big register. Historically it used to be possible to buy EPROMs with these register bits on the same chip. The clock signal determining the clock rate, which is the cycle time of the system, primarily clocks this register. References Further reading (132 pages) (79 pages) Instruction processing Firmware
