Emancipation in the Caribbean, referred to as the abolition of slavery in the British West Indies colonies, formally took effect on August 1, 1834, with the Slavery Abolition Act of 1833, which was precipitated by the Haitian Slave Rebellion of the late 1790s. It was originally led by an enslaved Dutty Bookman of Jamaica and then led by a Haitian black slave owner, Toussaint Louverture.
