Stamp issuing began as a French colony in 1922. Originally occupied by France as part of French Congo (1897-1903), then a dependency (1904-1914), later a territory of the French colony of Ubangi-Shari-Chad (1914-20). The northern part was added to the territory in 1913-14 and Chad became an independent French colony in 1920. It became an autonomous republic on 28 November 1958 and proclaimed independence on 11 August 1960.
Stamps of Middle Congo, used prior to 1922, were first overprinted "TCHAD" and then as "AFRIQUE ÉQUATORIALE FRANÇAISE". From 1936 to 1969, Chad used regular issues of French Equatorial Africa. Republican issues of Chad, with the name "RÉPUBLIQUE DU TCHAD" appeared in 1959, on the first anniversary of proclamation of the autonomous republic.
