British West Africa as a colonial entity was originally known as Colony of Sierra Leone and its Dependencies, then British West African Territories and finally British West African Settlements. It constituted during two periods (17 October 1821, until its first dissolution on 13 January 1850, and again 19 February 1866, until its final demise on 28 November 1888) as an administrative entity under a governor-in-chief (comparable in rank to a governor-general), an office vested in the governor of Sierra Leone (at Freetown).
