Thomas Clarkson (1760–1846) was a leading campaigner against slavery and the African slave trade. After graduating from St. John's College, Cambridge in 1783, Clarkson with Granville Sharp (1735–1813) founded the Committee for the Abolition of the African Slave Trade in 1787, which increased popular support for abolition and was the main campaigner behind the abolition of the slave trade. These volumes, first published in 1808, contain a unique contemporary account of the abolition movement from one of its major leaders. Clarkson describes in great detail the Quaker background to the abolitionist movement and the parliamentary debates leading to the Slave Trade Act of 1807. The contemporary arguments both in support and in opposition to abolition and the researches and actions of the abolition movement's members are described, creating an important historical record of the movement. Volume 1 contains the early history of the abolition movement until July 1788.
