British Togoland, officially the Mandate Territory of Togoland and later officially the Trust Territory of Togoland, was a territory in West Africa, under the administration of the United Kingdom. Initially it was a League of Nations Class B mandate. Subsequently, it was a United Nations Trust Territory. It was effectively formed in 1916 by the splitting of the occupied German protectorate of Togoland into two territories, French Togoland and British Togoland, during the First World War. In 1922, British Togoland was formally placed under British rule while French Togoland, now Togo, was placed under French rule.
