Who led the movement to abolish the slave trade in Britain?

William Wilberforce was a key figure in the movement to abolish the slave trade in Britain. He was a Member of Parliament who dedicated much of his political life to campaigning against slavery. His efforts included introducing bills to Parliament aimed at ending the slave trade, organizing petitions, and working closely with abolitionist groups and other reformers, including Thomas Clarkson. Wilberforce's persistence over many years contributed significantly to the public awareness of the issues surrounding the slave trade and ultimately led to the passage of the Abolition of the Slave Trade Act in 1807. His leadership and moral arguments helped galvanize public opinion, making him one of the most prominent faces of this pivotal movement in British history.
