The Nova Scotian Settlers, or Sierra Leone Settlers, were African Americans who founded the settlement of Freetown, Sierra Leone and the Colony of Sierra Leone, on March 11, 1792. The majority of these black American immigrants were among 3,000 African Americans, mostly former slaves, who had sought freedom and refuge with the British during the American Revolutionary War, leaving rebel masters. They became known as the Black Loyalists. The Nova Scotian Settlers were jointly led by African American Thomas Peters, a former soldier, and English abolitionist John Clarkson. For most of the 19th century, the Settlers resided in Settler Town and remained a distinct ethnic group within the Freetown territory, tending to marry among themselves and with Europeans in the colony.
