A host of evangelical causes sallied forth from quiet little Clapham: The Church Missionary Society (1799), the British and Foreign Bible Society (1804), The Society for Bettering the Condition of the Poor (1796), The Society for the Reformation of Prison Discipline and many more. The greatest labor of all, however, centered on the campaign against slavery. The first battle was for the abolition of the slave trade, that is, the capturing of Negroes in Africa, and shipping them for sale to the West Indies.
