Movement to abolish slavery

Overview

The Somersett case in 1772, in which a fugitive slave was freed with the judgement that slavery did not exist under English common law, helped launch the British movement to abolish slavery. Though anti-slavery sentiments were widespread by the late 18th century, many colonies and emerging nations continued to use slave labor: Dutch, French, British, Spanish, and Portuguese territories in the West Indies, South America, and the Southern United States. After the American Revolution established the United States, many Loyalists who fled the Northern United States immigrated to the British province of Quebec, bringing an English majority population as well as many slaves, leading the province to ban the institution in 1793 (see Slavery in Canada). In 1787, the Society for Effecting the Abolition of the Slave Trade was formed in London.
