On 25 March 1807, the British Parliament passed the Abolition of the Slave Trade Act, outlawing the transatlantic slave trade across the British Empire.
Championed by abolitionists such as William Wilberforce, the legislation imposed a hefty penalty of £120 per enslaved person found aboard British ships, effectively crippling the brutal trade.
While slavery itself remained legal in British territories until 1833, this landmark act was a crucial first step in dismantling the institution of human bondage and set a powerful precedent for abolitionist movements worldwide.
