It was located opposite from the Congolese city of Yakoma in the area of the present-day Central African Republic.
The Frenchman Gaston Gaillard then received a grant from the Yakoma leader Inkesse on the north bank[1] and established Abiras on September 7, 1891.
[2] During the initial French settlement of central Africa, Abiras served as the capital of the French Congo's territory of Upper Ubangi (Haut-Oubangui) and then as the first capital of the colony of Ubangi-Shari (Oubangui-Chari).
[3] It was replaced in 1906 first by Fort de Possel and then by Bangi, the present-day Bangui.
[4] Coordinates are based on aerial photographs; a statement that in 1894, "a large French expedition had massed at Abiras (junction of the Wellé and Mbomu Rivers)";[5] and a statement "Elsewhere we learn that Abiras, at the mouth of the Mbomu...".
