Through Slavery, Christianity and Poster

Adam Hochschild posits that this anti-slavery movement is the first peaceful social movement which all modern social movements are built upon.

A number of the founders had been meeting at George Yard since 1783, and over four years grew their circle of friends to include Thomas Clarkson, an unknown at that time.

The society was established by twelve men; including individuals who later became prominent campaigners, such as Thomas Clarkson and Granville Sharp. As Anglicans they were able to be more influential in Parliament than the more numerous Quaker founding members - given Nonconformists were not allowed to hold positions of power. The society worked to educate the public about the abuses of the slave trade and achieved the abolition of the international slave trade when the British Parliament passed the Slave Trade Act 1807, at which time the society ceased its activities. (The United States also prohibited the African slave trade the same year, to take effect in 1808.)

In 1823 the Society for the Mitigation and Gradual Abolition of Slavery Throughout the British Dominions (also known as the Anti-Slavery Society) was founded, which worked to abolish the institution of slavery throughout the British colonies. Abolition was passed by parliament in 1833 (except in India, where it was part of the indigenous culture); with emancipation completed by 1838.

It is a forgotten irony that Quakers and Nonconformists, who founded the Society, were denied equality until the Catholic Emancipation Act 1829, 22 years after the Slave Trade Act 1807 was passed.

Historical background

Until the second half of the 18th century, the near-universal view of slavery was that it was an "unfortunate condition", something that nobody wanted to happen to themselves, but perfectly acceptable in other people. This thinking went back to its origins in prehistory. In the last quarter of the 18th century, there was a big swing in public opinion against slavery; 1.7 million people in Britain signed petitions seeking to abolish the slave trade. These ideas were held across the boundaries of social class. This U-turn in thinking in such a relatively short time may never be understood, but is suggested by David Eltis to be associated with a steadily less violent world and, in the English-speaking 18th century, an active and relatively free press, coupled with high literacy rates.

The first anti-slavery statement was written by Dutch and German Quakers, who met at Germantown, Pennsylvania in 1688. English Quakers began to express their official disapproval of the slave trade in 1727 and promote reforms. From the 1750s, a number of Quakers in Britain's American colonies also began to oppose slavery and called on English Quakers to take action with parliament. They encouraged their fellow citizens, including Quaker slave owners, to improve conditions for slaves, educate their slaves in Christianity, reading and writing, and gradually emancipate (free) them.

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 were also influenced by the publicity that year about the Zong massacre, as the shipowners were litigating a claim for insurance against losses due to more than 132 slaves having been killed on their ship.
