David Walker, (born 1796/97?, Wilmington, North Carolina, U.S.—died August 6, 1830, Boston, Massachusetts), African American abolitionist whose pamphlet Appeal…to the Colored Citizens of the World… (1829), urging slaves to fight for their freedom, was one of the most radical documents of the antislavery movement.

“[I promise]…to demonstrate in the course of…my Appeal…that we Coloured People of these United States, are, the most wretched, degraded and abject set of beings that ever lived since the world began, down to the present day, and that the white Christians of America, who hold us in slavery, (or, more properly speaking, pretenders to Christianity,) treat us more cruel and barbarous than any Heathen nation did any people whom it had subjected, or reduced to the same condition.…I advance it therefore to you…as an unshaken and forever immoveable fact, that your full glory and happiness, as well as all other coloured people under Heaven, shall never be fully consummated, but with the entire emancipation of your enslaved brethren all over the world.
