During World War II, the Vichy regime remained in control until 1943, when members of General Charles de Gaulle's provisional government assumed control of all French West Africa. The Brazzaville Conference of 1944, the first Constituent Assembly of the Fourth Republic in 1946, and France's gratitude for African loyalty during World War II, led to far-reaching governmental reforms in 1946. French citizenship was granted to all African "subjects", the right to organize politically was recognized, and various forms of forced labour were abolished. Between the years 1944 and 1946 many national conferences and constituent assemblies took place between France's Vichy regime and provisional governments in Ivory Coast. Governmental reforms were established by late 1946, which granted French citizenship to all African "subjects" under the colonial control of the French.
