Faya-Largeau[2] (also known as Faya,[3] ar|فايا لارجو or Arabic: فايا) is the largest city in northern Chad and was the capital of the region of Bourkou-Ennedi-Tibesti.[4] It is now in the Borkou Region, which was formed in 2008 from the Borkou Department of the former Bourkou-Ennedi-Tibesti region.
Originally called Faya, the town was renamed Largeau after French Colonel Victor Emmanuel Largeau;[3] upon Chadian independence from France, it assumed the name Faya-Largeau. The town was captured by Libya when Libya annexed the Aouzou Strip in 1975, but was retaken by Hissène Habré's forces in 1980.[5] Libya recaptured Faya-Largeau in 1983, but retreated in 1987 during the so-called Toyota War.[5]
Due to the considerable underground water supply in the town, the main economic activities are agriculture and natron mining. The town is serviced by Faya-Largeau Airport [6] with a paved runway, used almost exclusively by military airplanes.
