British Parliament bans the Atlantic slave trade after 20 years of campaigning

Britain’s Atlantic slave trade abolition became law on 25 March 1807, when King George III signed the Slave Trade Act after two decades of failed attempts. The final Commons vote was 283 to 16, the culmination of a campaign carried by Quakers, formerly enslaved writers like Olaudah Equiano, and petitioners across the country. It was the first time a major empire legislated against its most profitable trade on moral grounds.
