Twelve Years a Slave is an 1853 memoir and slave narrative by Solomon Northup as told to and written by David Wilson. Northup, a black man who was born free in New York state, details himself being tricked to go to Washington, D.C., where he was kidnapped and sold into slavery in the Deep South. He was in bondage for 12 years in Louisiana before he was able to secretly get information to friends and family in New York, who in turn secured his release with the aid of the state. Northup's account provides extensive details on the slave markets in Washington, D.C., and New Orleans, and describes at length cotton and sugar cultivation and slave treatment on major plantations in Louisiana.

The slave narrative is a type of literary genre involving the (written) autobiographical accounts of enslaved persons, particularly Africans enslaved in the Americas, though many other examples exist. Over six thousand such narratives are estimated to exist; about 150 narratives were published as separate books or pamphlets. In the United States during the Great Depression (1930s), more than 2,300 additional oral histories on life during slavery were collected by writers sponsored and published by the Works Progress Administration, a New Deal program. Most of the 26 audio-recorded interviews are held by the Library of Congress.
