France's imposition of a head tax in 1900 to support the colony's public works program provoked protests. Many Ivorians saw the tax as a violation of the protectorate treaties because they felt that France was demanding the equivalent of a ''coutume'' from the local kings, rather than the reverse. Many, especially in the interior, also considered the tax a humiliating symbol of submission. In 1905, the French officially abolished slavery in most of French West Africa. From 1904 to 1958, Ivory Coast was part of the Federation of French West Africa. It was a colony and an overseas territory under the Third Republic. In World War I, France organized regiments from Ivory Coast to fight in France, and colony resources were rationed from 1917 to 1919. Until the period following World War II, governmental affairs in French West Africa were administered from Paris. France's policy in West Africa was reflected mainly in its philosophy of "association", meaning that all Africans in Ivory Coast were officially French "subjects", but without rights to representation in Africa or France.
