William Wilberforce (24 August 1759 – 29 July 1833) was a British politician, philanthropist, and a leader of the movement to abolish the Atlantic slave trade. A native of Kingston upon Hull, Yorkshire, he began his political career in 1780, and became an independent Member of Parliament (MP) for Yorkshire (1784–1812). In 1785, he underwent a conversion experience and became an evangelical Anglican, which resulted in major changes to his lifestyle and a lifelong concern for reform.
In 1787, Wilberforce came into contact with Thomas Clarkson and a group of activists against the transatlantic slave trade, including Granville Sharp, Hannah More and Charles Middleton. They persuaded Wilberforce to take on the cause of abolition, and he became a leading English abolitionist. He headed the parliamentary campaign against the British slave trade for 20 years until the passage of the Slave Trade Act 1807.
