A Mediaeval kingdom in northern Chad, in the Tibesti Highlands beyond the Bodele Depression, established by Berber nomads and especially influential from c. 1000 to c. 1350 CE. Almost no hard data is known about this place, although the Zaghawa as an identifiable Berber ethnic group exist to this day - they are now nomads, living in northern and northeastern Chad, and in neighbouring Darfur region of Sudan. It is known that Zaghawa was important in the Islamicization of Kanem, to the south, c. 1100.
