Sutton Elbert Griggs (June 19, 1872 - January 2, 1933) was an African-American author, Baptist minister, and social activist. He is best known for his novel Imperium in Imperio, a utopian work that envisions a separate African-American state within the United States. Griggs was a prolific author, writing more than thirty books and pamphlets in his lifetime and selling them door-to-door or at the revival meetings at which he preached. His first novel, Imperium in Imperio, published in 1899, is his most famous. In 1901, Griggs founded the Orion Publishing Company to sell books to the African American market. None of his four subsequent novels achieved the success of Imperium in Imperio, but he produced a steady stream of social and religious tracts, as well as an autobiography.
