David Walker, Frederick Douglass, and Sojourner Truth. While Garrison is considered the prime organizer of the abolitionist movement, David Walker published his Appeal two years before The Liberator. In 1829, Walker declared slavery a malignancy, calling for its immediate termination. The abolitionists gave birth two very successful movements: Prohibition and Women's suffrage. Many in the abolition movement went on to play significant roles in these movements and both made much of moral arguments. Suffrage benefited from the rise of progressiveness and the support of male progressive politicians.
