French Dahomey was a French colony of and a part of French West Africa from 1904 to 1958. After World War II, by the establishment of the French Fourth Republic in 1947, Dahomey became part of the French Union with an increased autonomy. On 11 December 1958, the French Fifth Republic was established and the French Union became the French Community. The colony became the self-governing Republic of Dahomey within the Community, and two years later on 1 August 1960 it gained full independence (and in 1975 changed its name to Benin).
