By 1783, an anti-slavery movement to abolish the slave trade throughout the Empire had begun among the British public, with the Society for Effecting the Abolition of the Slave Trade being established in 1787. Spurred by an incident involving Chloe Cooley, a slave brought to Canada by an American Loyalist, the Lieutenant-Governor of Upper Canada, John Graves Simcoe, tabled the Act Against Slavery in 1793. Passed by the local Legislative Assembly, it was the first legislation to outlaw the slave trade in a part of the British Empire.
