Abolitionism in the United Kingdom was the movement in the late 18th and early 19th centuries to end the practice of slavery, whether formal or informal, in the United Kingdom, the British Empire and the world, including ending the Atlantic slave trade. It was part of a wider abolitionism movement in Western Europe and the Americas.
The buying and selling of slaves was made illegal across the British Empire in 1807, but owning slaves overseas was permitted until it was outlawed completely in 1833, beginning a process where from 1834 slaves became indentured "apprentices" to their former owners until emancipation was achieved for the majority by 1840 and for remaining exceptions by 1843.
Origins
In the 17th and early 18th centuries, English Quakers and a few evangelical religious groups condemned slavery (by then applied mostly to Africans) as un-Christian. A few secular thinkers of the Enlightenment criticised it for violating the rights of man. James Edward Oglethorpe was the first to act on the Enlightenment case against slavery on humanistic grounds. In his "Georgia Experiment" he convinced Parliament to ban slavery in his Province of Georgia from 1735. However, slavery was reinstated in 1751. He also encouraged his friends Granville Sharp and Hannah More to pursue the cause vigorously. Soon after his death in 1785, they joined with William Wilberforce and others in forming the Clapham Sect.
The slave trade had been banned in England in 1102, by the Church Council of London, convened by Anselm. However, the council had no legislative powers, unless decreed and signed by the monarch. In Cartwright's Case of 1569 regarding the punishment of a slave from Russia, the court ruled that English law could not recognise slavery, as it was never established officially. This ruling was overshadowed by later developments. It was upheld in 1700 by Lord Chief Justice Sir John Holt when he ruled that "As soon as a man sets foot on English ground he is free".
English colonists imported slaves to the North American colonies and by the 18th century, traders began to import slaves from Africa, India and East Asia (where they were trading) to London and Edinburgh to work as servants. Men who migrated to the North American colonies often took their East Indian slaves or servants with them, as East Indians have been documented in colonial records. David Olusoga wrote of the sea change that had taken place:
To fully understand how remarkable the rise of British abolitionism was, both as a political movement and as a popular sentiment, it is important to remember how few voices were raised against slavery in Britain until the last quarter of the eighteenth century.
Some of the first freedom suits, court cases in Britain to challenge the legality of slavery, took place in Scotland in 1755 and 1769. The cases were Montgomery v. Sheddan (1755) and Spens v. Dalrymple (1769). Each of the slaves had been baptised in Scotland and challenged the legality of slavery. They set the precedent of legal procedure in British courts that would later lead to success for the plaintiffs. In these cases, deaths of the plaintiff and defendant, respectively, brought an end to the action before a court decision could be rendered.
African slaves were not bought or sold in London but were brought by masters from other places. Together with people from other nations, especially non-Christian ones, Africans were considered foreigners and thus ineligible to be English subjects; England had no naturalisation procedure. The African slaves' legal status was unclear until Somersett's Case in 1772, when the fugitive slave James Somersett forced a decision by the courts. Somersett had escaped and his master, Charles Steuart, had him captured and imprisoned on board a ship, intending to ship him to Jamaica to be resold into slavery. While in London, Somersett had been baptised and three godparents issued a writ of habeas corpus. As a result, Lord Mansfield, Chief Justice of the Court of the King's Bench, had to judge whether Somersett's abduction was lawful or not under English Common Law. No legislation had ever been passed to establish slavery in England. The case received national attention and five advocates supported the action on behalf of Somersett.
In his judgment of 22 June 1772, Mansfield held,
