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, which subsequently entered into union with Ghana, part becoming its Volta Region. It was effectively formed in 1916 by the splitting of the German protectorate of Togoland into two territories, French Togoland and British Togoland, during the First World War. Initially, it was a League of Nations Class B mandate.
