William Wilberforce was an English politician and philanthropist. In 1785, Wilberforce became an Evangelical, which brought enormous changes to his life. He became involved in abolitionist causes in 1787, and headed the parliamentary campaign against the slave trade for twenty years, until the passage of the Slave Trade Act of 1807. He was also actively involved with the Society for Effecting the Abolition of the Slave Trade, a British abolitionist group.
