African-American literature is the body of literature produced in the United States by writers of African descent. It begins with the works of such late 18th-century writers as Phillis Wheatley. Before the high point of slave narratives, African-American literature was dominated by autobiographical spiritual narratives. The genre known as slave narratives in the 19th century were accounts by people who had generally escaped from slavery, about their journeys to freedom and ways they claimed their lives. The Harlem Renaissance of the 1920s was a great period of flowering in literature and the arts, influenced both by writers who came North in the Great Migration and those who were immigrants from Jamaica and other Caribbean islands. African-American writers have been recognized by the highest awards, including the Nobel Prize given to Toni Morrison in 1993. Among the themes and issues explored in this literature are the role of African Americans within the larger American society, African-American culture, racism, slavery, and social equality. African-American writing has tended to incorporate oral forms, such as spirituals, sermons, gospel music, blues, or rap.
