Dar Tama Department

Dar Tama (دار تاما) is one of three departments in Wadi Fira, a region of Chad. Its capital is Gueréda, 165 km northeast of Abéché. The population consists primarily of non-Arab tribes. Dar Tama is the historical home of the Tama, who make up the majority of the population. The Zaghawa make up a significant minority and migrated during the Sahelian drought in the 1980s. Both are non-Arab tribes. Former Chadian president Idriss Déby is from the Zaghawa tribe.
