The slave narrative is a type of literary work that is made up of the written accounts of enslaved Africans in Great Britain and its colonies, including the later United States, Canada, and Caribbean nations. Some six thousand former slaves from North America and the Caribbean gave accounts of their lives during the 18th and 19th centuries, with about 150 narratives published as separate books or pamphlets. In the U.S. 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 (WPA) of President Franklin D. Roosevelt's administration. Most of the 26 audio-recorded interviews are held by the Library of Congress.
