The abolition campaign was started by the Quakers. A fundamental Quaker belief is that all people are created equal in the eyes of God. English Quakers began to express their official disapproval of the slave trade around 1727 and promote reforms. From the 1750s, a number of Quakers in the American colonies also began to oppose slavery. An informal group of six Quakers pioneered the British abolitionist movement in 1783 when the London Society of Friends' yearly meeting presented its petition against the slave trade to parliament, signed by over 300 Quakers. They subsequently decided to form a small, non-denominational group to gain wider Anglican and Parliamentary support. The new committee had nine Quaker members and three evangelical Anglicans, which strengthened the committee's influence as Quakers were debarred from standing for Parliament. The three Anglicans who co-founded the committee were Granville Sharp, Thomas Clarkson, and William Wilberforce. The Quaker members were: John Barton; William Dillwyn; George Harrison; Samuel Hoare Jr; Joseph Hooper; John Lloyd; Joseph Woods Sr; James Phillips; and Richard Phillips. Five of these had been part of the informal group of six that had pioneered the movement in 1783. A bill that made it unlawful for any British subject to capture and transport slaves was finally became law in 1807. However, it was not until 1833 that Parliament passed the Slavery Abolition Act, Quakers continued to work for the movement and provide financial support throughout the campaign.
