Abolition of Atlantic Slave Trade

Date: March 25, 1807 • Location: London, United Kingdom

The Slave Trade Act, which abolished the Atlantic slave trade in the British Empire, received royal assent.

The Slave Trade Act 1807, or the Abolition of Slave Trade Act 1807, was an act of the Parliament of the United Kingdom prohibiting the Atlantic slave trade in the British Empire. Although it did not automatically emancipate those enslaved at the time, it encouraged British action to press other nation states to abolish their own slave trades. It took effect on 1 May 1807, after 18 years of trying to pass an abolition bill.
