Question: What abolished slavery throughout the sovereignty imperialism is most often associated with?

full_context: Document 1: Imperialism: The principles of imperialism are often generalizable to the policies and practices of the British Empire "during the last generation, and proceeds rather by diagnosis than by historical description". British imperialism often used the concept of Terra nullius (Latin expression which stems from Roman law meaning 'empty land'). The country of Australia serves as a case study in relation to British settlement and colonial rule of the continent in the eighteenth century, as it was premised on terra nullius, and its settlers considered it unused by its sparse Aboriginal inhabitants.
Document 2: New York City: Under New York State's gradual abolition act of 1799, children of slave mothers were born to be eventually liberated but were held in indentured servitude until their mid-to-late twenties. Together with slaves freed by their masters after the Revolutionary War and escaped slaves, a significant free-black population gradually developed in Manhattan. Under such influential United States founders as Alexander Hamilton and John Jay, the New York Manumission Society worked for abolition and established the African Free School to educate black children. It was not until 1827 that slavery was completely abolished in the state, and free blacks struggled afterward with discrimination. New York interracial abolitionist activism continued; among its leaders were graduates of the African Free School. The city's black population reached more than 16,000 in 1840.
Document 3: Imperialism: A resurgence came in the late 19th century, with the Scramble for Africa and major additions in Asia and the Middle East. The British spirit of imperialism was expressed by Joseph Chamberlain and Lord Rosebury, and implemented in Africa by Cecil Rhodes. The pseudo-sciences of Social Darwinism and theories of race formed an ideological underpinning during this time. Other influential spokesmen included Lord Cromer, Lord Curzon, General Kitchner, Lord Milner, and the writer Rudyard Kipling. The British Empire was the largest Empire that the world has ever seen both in terms of landmass and population. Its power, both military and economic, remained unmatched.
Document 4: Saint Helena: Although the importation of slaves to St Helena had been banned in 1792, the phased emancipation of over 800 resident slaves did not take place until 1827, which was still some six years before the British Parliament passed legislation to ban slavery in the colonies.
Document 5: Imperialism: The First British Empire was based on mercantilism, and involved colonies and holdings primarily in North America, the Caribbean, and India. Its growth was reversed by the loss of the American colonies in 1776. Britain made compensating gains in India, Australia, and in constructing an informal economic empire through control of trade and finance in Latin America after the independence of Spanish and Portuguese colonies about 1820. By the 1840s, Britain had adopted a highly successful policy of free trade that gave it dominance in the trade of much of the world. After losing its first Empire to the Americans, Britain then turned its attention towards Asia, Africa, and the Pacific. Following the defeat of Napoleonic France in 1815, Britain enjoyed a century of almost unchallenged dominance and expanded its imperial holdings around the globe. Increasing degrees of internal autonomy were granted to its white settler colonies in the 20th century.
Document 6: Slavery in international law: The concept has its roots in the 1807 Abolition of Slavery Act of Great Britain. Many academics in the field perceive this as the beginning of the end of the traditional form of slavery: chattel slavery. In the 19th century, Britain controlled the majority of the world through its colonies. Consequently, in passing this law to abolish slavery, the British Parliament abolished slavery in the vast majority of its colonies.
Document 7: Imperialism: Imperialism is a type of advocacy of empire. Its name originated from the Latin word "imperium", which means to rule over large territories. Imperialism is "a policy of extending a country's power and influence through colonization, use of military force, or other means". Imperialism has greatly shaped the contemporary world. It has also allowed for the rapid spread of technologies and ideas. The term imperialism has been applied to Western (and Japanese) political and economic dominance especially in Asia and Africa in the 19th and 20th centuries. Its precise meaning continues to be debated by scholars. Some writers, such as Edward Said, use the term more broadly to describe any system of domination and subordination organised with an imperial center and a periphery.
Document 8: Imperialism: In anglophone academic works, theories regarding imperialism are often based on the British experience. The term "Imperialism" was originally introduced into English in its present sense in the late 1870s by opponents of the allegedly aggressive and ostentatious imperial policies of British prime Minister Benjamin Disraeli. It was shortly appropriated by supporters of "imperialism" such as Joseph Chamberlain. For some, imperialism designated a policy of idealism and philanthropy; others alleged that it was characterized by political self-interest, and a growing number associated it with capitalist greed. Liberal John A. Hobson and Marxist Vladimir Lenin added a more theoretical macroeconomic connotation to the term. Lenin in particular exerted substantial influence over later Marxist conceptions of imperialism with his work Imperialism, the Highest Stage of Capitalism. In his writings Lenin portrayed Imperialism as a natural extension of capitalism that arose from need for capitalist economies to constantly expand investment, material resources and manpower in such a way that necessitated colonial expansion. This conception of imperialism as a structural feature of capitalism is echoed by later Marxist theoreticians. Many theoreticians on the left have followed in emphasizing the structural or systemic character of "imperialism". Such writers have expanded the time period associated with the term so that it now designates neither a policy, nor a short space of decades in the late 19th century, but a world system extending over a period of centuries, often going back to Christopher Columbus and, in some accounts, to the Crusades. As the application of the term has expanded, its meaning has shifted along five distinct but often parallel axes: the moral, the economic, the systemic, the cultural, and the temporal. Those changes reflect - among other shifts in sensibility - a growing unease, even squeamishness, with the fact of power, specifically, Western power.
Document 9: British Empire: The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 7001230000000000000 ♠ 23% of the world population at the time, and by 1920, it covered 35,500,000 km (13,700,000 sq mi), 7001240000000000000 ♠ 24% of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase ``the empire on which the sun never sets ''was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.
Document 10: Imperialism: During the 20th century, historians John Gallagher (1919–1980) and Ronald Robinson (1920–1999) constructed a framework for understanding European imperialism. They claim that European imperialism was influential, and Europeans rejected the notion that "imperialism" required formal, legal control by one government over another country. "In their view, historians have been mesmerized by formal empire and maps of the world with regions colored red. The bulk of British emigration, trade, and capital went to areas outside the formal British Empire. Key to their thinking is the idea of empire 'informally if possible and formally if necessary.'"[attribution needed] Because of the resources made available by imperialism, the world's economy grew significantly and became much more interconnected in the decades before World War I, making the many imperial powers rich and prosperous.
Document 11: Protestantism: Also, other human rights were advocated for by some Protestants. For example, torture was abolished in Prussia in 1740, slavery in Britain in 1834 and in the United States in 1865 (William Wilberforce, Harriet Beecher Stowe, Abraham Lincoln - against Southern Protestants). Hugo Grotius and Samuel Pufendorf were among the first thinkers who made significant contributions to international law. The Geneva Convention, an important part of humanitarian international law, was largely the work of Henry Dunant, a reformed pietist. He also founded the Red Cross.
Document 12: British Empire: With support from the British abolitionist movement, Parliament enacted the Slave Trade Act in 1807, which abolished the slave trade in the empire. In 1808, Sierra Leone was designated an official British colony for freed slaves. The Slavery Abolition Act passed in 1833 abolished slavery in the British Empire on 1 August 1834 (with the exception of St. Helena, Ceylon and the territories administered by the East India Company, though these exclusions were later repealed). Under the Act, slaves were granted full emancipation after a period of 4 to 6 years of "apprenticeship".
Document 13: Slave Trade Act 1807: The Slave Trade Act 1807, officially An Act for the Abolition of the Slave Trade, was an Act of the Parliament of the United Kingdom prohibiting the slave trade in the British Empire. Although it did not abolish the practice of slavery, it did encourage British action to press other nations states to abolish their own slave trades.
Document 14: British Empire: Two years later, the Royal African Company was inaugurated, receiving from King Charles a monopoly of the trade to supply slaves to the British colonies of the Caribbean. From the outset, slavery was the basis of the British Empire in the West Indies. Until the abolition of the slave trade in 1807, Britain was responsible for the transportation of 3.5 million African slaves to the Americas, a third of all slaves transported across the Atlantic. To facilitate this trade, forts were established on the coast of West Africa, such as James Island, Accra and Bunce Island. In the British Caribbean, the percentage of the population of African descent rose from 25 percent in 1650 to around 80 percent in 1780, and in the 13 Colonies from 10 percent to 40 percent over the same period (the majority in the southern colonies). For the slave traders, the trade was extremely profitable, and became a major economic mainstay for such western British cities as Bristol and Liverpool, which formed the third corner of the so-called triangular trade with Africa and the Americas. For the transported, harsh and unhygienic conditions on the slaving ships and poor diets meant that the average mortality rate during the Middle Passage was one in seven.
Document 15: Baptists: Elsewhere in the Americas, in the Caribbean in particular, Baptist missionaries took an active role in the anti-slavery movement. In Jamaica, for example, William Knibb, a prominent British Baptist missionary, worked toward the emancipation of slaves in the British West Indies (which took place in 1838). Knibb also protagonised the creation of "Free Villages"; rural communities centred around a Baptist church where emancipated slaves could farm their own land. Baptists were likewise active in promoting the education of former slaves; for example, Jamaica's Calabar High School, named after the slave port of Calabar, was formed by Baptist missionaries. At the same time, during and after slavery, slaves and free formed their own Spiritual Baptist movements - breakaway spiritual movements which often expressed resistance to oppression.
