This is the best work on the history of the Abolitionist movement that led to the end of slavery in Britain and its colonies, and it is replete with extraordinary and disquieting anecdotes. The three plates include the engraving of the cross-section and plan of a slave ship, which, as Clarkson writes, made "an instantaneous impression of horror upon all who saw it." While at Oxford studying to become a clergyman, he wrote a prizewinning essay on slavery, and subsequently had a moment of conversion when "a thought came into my mind, that if the contents of the Essay were true, it was time some person should see these calamities to their end." Although his efforts undermined his health and fortune, in time he became a figure of enormous moral influence in Abolitionist circles, and he ranks with Wilberforce as an architect of the act abolishing slavery in the British empire that was ultimately passed in 1833.
