Maryland State Colonization Society
The Maryland State Colonization Society was the Maryland branch of the American Colonization Society, an organization founded in 1816 with the purpose of sending free African Americans to what many Southerners considered greater freedom in Africa. The ACS helped to found the colony of Liberia in 1821–22, as a place for freedmen.
