The Online Library of Liberty

One of the great movements for liberty was the abolitionist movement in the late 18th and 19th centuries. It was led by figures like the Quaker Thomas Clarkson who successfully agitated for the abolition of the slave trade in Britain. He wrote histories and other works which exposed the cruelty and inhumanity of slavery. In his History of the Abolition of the Slave-trade he used illustrations very effectively in order to make his case, as these examples show.
