The slave narrative is a type of literary genre involving the (written) autobiographical accounts of enslaved Africans, particularly in the Americas. 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.Some of the earliest memoirs of captivity known in the English-speaking world were written by white Europeans and later Americans, captured and sometimes enslaved in North Africa by local Muslims, usually Barbary pirates. These were part of a broad category of "captivity narratives". Beginning in the 17th century, these included accounts by colonists and later American settlers in North America and the United States who were captured and held by Native Americans. Several well-known captivity narratives were published before the American Revolution, and they often followed forms established with the narratives of captivity in North Africa. North African accounts did not continue to compile after the Napoleonic Era; accounts from North Americans, captured by western tribes migrating west continued until the end of the 19th century. Given the problem of international contemporary slavery in the 20th and 21st centuries, additional slave narratives are being written and published. Source: Wikipedia (en)
