Frederick Douglass was an American social reformer, abolitionist, orator, writer, and statesman. After escaping from slavery in Maryland, he became a national leader of the abolitionist movement in Massachusetts and New York, becoming famous for his oratory and incisive antislavery writings. Accordingly, he was described by abolitionists in his time as a living counterexample to slaveholders' arguments that slaves lacked the intellectual capacity to function as independent American citizens. Northerners at the time found it hard to believe that such a great orator had once been a slave. It was in response to this disbelief that Douglass wrote his first autobiography.
Following the Civil War, Douglass was an active campaigner for the rights of freed slaves . Douglass also actively supported women's suffrage, and he held several public offices. Without his permission, Douglass became the first African American nominated for vice president of the United States, as the running mate of Victoria Woodhull on the Equal Rights Party ticket.
Douglass believed in dialogue and in making alliances across racial and ideological divides, as well as in the liberal values of the U.S. Constitution. When radical abolitionists, under the motto "No Union with Slaveholders", criticized Douglass's willingness to engage in dialogue with slave owners, he replied: "I would unite with anybody to do right and with nobody to do wrong.
