This five-volume documentary collection - culled from an international archival search that turned up over 14,000 letters, speeches, pamphlets, essays, and newspaper editorials - reveals how black abolitionists represented the core of the antislavery movement. While the first two volumes consider black abolitionists in the British Isles and Canada (the home of some 60,000 black Americans on the eve of the Civil War), the remaining volumes examine the activities and opinions of black abolitionists in the United States from 1830 until the end of the Civil War. In particular, these volumes focus on their reactions to African colonization and the idea of gradual emancipation, the Fugitive Slave Law, and the promise brought by emancipation during the war.
