2015 Reprint of Third and Last edition of 1830. David Walker was an outspoken African-American abolitionist and anti-slavery activist. In 1829, while living in Boston, Massachusetts, he first published his famous Appeal, a call for black unity and self-help in the fight against oppression and injustice. The work brought attention to the abuses and inequities of slavery and the obligation of individuals to act responsibly for racial equality, according to religious and political tenets. At the time, some people were outraged and fearful of the reaction that the pamphlet would have. Many abolitionists thought the views were extreme. Historians and liberation theologians cite the Appeal as an influential political and social document of the 19th century. Walker exerted a radicalizing influence on the abolitionist movements of his day and inspired future black leaders and activists.
