Revelation of the horrors of slavery
It was at Cambridge in 1785 that Clarkson entered a Latin essay competition that was to set him on the course for most of the remainder of his life. The topic of the essay, set by university vice-chancellor Peter Peckard, was Anne liceat invitos in servitutem dare (Is it lawful to enslave the unconsenting?),[2] and it led Clarkson to consider the question of the slave trade. He read everything he could on the subject, including the works of Anthony Benezet, a Quaker abolitionist. Appalled and challenged by what he discovered, Clarkson changed his life. He also researched the topic by meeting and interviewing those who had personal experience of the slave trade and of slavery.
After winning the prize, Clarkson had what he called a spiritual revelation from God as he travelled on horseback between Cambridge and London. Having broken his journey at Wadesmill, near Ware, Hertfordshire, as he stopped, 'A thought came into my mind', he later wrote, 'that if the contents of the Essay were true, it was time some person should see these calamities to their end' (Clarkson, History, vol. 1). This experience and sense of calling ultimately led him to devote his life to abolishing the slave trade.
Having translated the essay into English so that it could gain a wider audience, Clarkson published it in 1786 as "An essay on the slavery and commerce of the human species, particularly the African, translated from a Latin Dissertation", which was honoured with the first prize in the University of Cambridge, for the year 1785.[3]
The publication of the essay had an immediate impact, and Clarkson was introduced to many others who were sympathetic to abolition, some of whom had already published and campaigned against slavery. These included influential men such as James Ramsay and Granville Sharp, the Quakers, and other Nonconformists. The movement had been gathering strength for some years, having been founded by Quakers both in Britain and in the United States, with support from other Nonconformists or from Puritans on both sides of the Atlantic. In 1783 three hundred Quakers, chiefly from the London area, presented the British Parliament with the first petition against the slave trade.
Following this step, a small offshoot group sought to form the Committee for the Abolition of the Slave Trade, a small non-denominational group that could lobby more successfully by incorporating Anglican and Parliamentary support (Quakers were disbarred from Parliament until the early nineteenth century, whereas the Anglican Church had the right to seats in the House of Lords). The twelve founding members included nine Quakers, and three pioneering Anglicans – Granville Sharp, Thomas Clarkson, and William Wilberforce — all evangelical Christians sympathetic to the religious revival that had predominantly nonconformist origins, but which sought wider non-denominational support for a "Great Awakening" amongst believers.
Anti-slavery campaign
Encouraged by publication of Clarkson’s essay, an informal committee was set up between small groups from the petitioning Quakers, Clarkson and others, with the aim of lobbying Members of Parliament (MPs). This was to lead, in May 1787, to the foundation of the Committee for the Abolition of the Slave Trade. The Committee included Granville Sharp as Chairman and Josiah Wedgwood as well as Clarkson himself. Clarkson also approached the young William Wilberforce, who as an (Evangelical) Anglican and an MP could offer them a link into the British Parliament. Wilberforce was one of very few parliamentarians to have had sympathy with the Quaker petition; he had already put a question about the slave trade before the House of Commons, marking himself out as one of the earliest Anglican abolitionists.
Clarkson took a leading part in the affairs of the Committee for the Abolition of the Slave Trade, and was given the responsibility to collect evidence to support the abolition of the slave trade. He faced much opposition from supporters of the trade in some of the cities he visited. The slave traders were an influential group because the trade was a legitimate and lucrative business, generating prosperity for many of the ports. On a visit to Liverpool in 1787, the year the Committee for the Abolition of the Slave Trade was founded, Clarkson was attacked and nearly killed by a gang of sailors paid to assassinate him. He just escaped with his life. That same year, Clarkson published the pamphlet: "A Summary View of the Slave Trade and of the Probable Consequences of Its Abolition".
