... The British abolished the slave trade in 1807, but not the institution itself. In 1816, slaves rose up in the largest major slave rebellion in the island's history. Twenty thousand slaves from over seventy plantations rebelled. They drove whites off the plantations, but widespread killings did not take place. This was later termed "Bussa's Rebellion" after the slave ranger, Bussa, who with his assistants hated slavery, found the treatment of slaves on Barbados to be "intolerable," and believed the political climate in the UK made the time ripe to peacefully negotiate with planters for freedom... Bussa's Rebellion failed. One hundred and twenty slaves died in combat or were immediately executed; another 144 were brought to trial and executed; remaining rebels were shipped off the island...Slavery was abolished in 1834 in Barbados, today's "History of" country.
ADDED: Here— at the U.K. National Archives website — is a school lesson on Bussa's rebellion, with nice scannings of original documents for students to read. And here's a drawing taken from the rebels that "appears to stress the rebels' loyalty to Britain and to the Crown while conveying their earnest desire for liberty."
