Bangui was founded by Albert Dolisie and Alfred Uzac on 26 June 1889, in what was then the upper reaches of the French Congo, the present-day Congo (Brazzaville). The original site was  south of the Ubangi rapids. Its territory was organized first into the territory of the Upper Ubangi ('''') and then as the separate colony of Ubangi-Shari. The initial capitals of these areas were at les Abiras and Fort de Possel further upstream, but the rapids at Bangui blocked them from direct communication along the river and caused the settlement there to grow in importance until, in 1906, it was chosen as the new headquarters for the French administration. Bangui retained its importance as a military and administrative centre when the colony was folded into French Equatorial Africa and under both Vichy and Free French control during World War II. The French operated a radio transmitter in Bangui, which was described in 1932 as "the most remote radio station in Africa".
