an African American abolitionist and orator. An advocate of militant abolitionism, Garnet was a prominent member of the abolition movement that led against moral suasion toward more political action. He joined the American Anti-Slavery Society and frequently spoke at abolitionist conferences. One of his most famous speeches, "Call to Rebellion," was delivered in 1843 to the National Negro Convention in Buffalo, New York. Disheartened by the hostile treatment of blacks in America, Garnet took a stance unpopular among black activists by supporting African colonization. He spent the last months of his life as minister to Liberia, a country in west Africa colonized by American ex-slaves and black freemen.
