The Kanuri people (kanuri, Kanuri, also Barnawi, Yerwa, Barebari and several subgroup names) are an African ethnic group living largely in the lands of the former Kanem and Bornu Empires in Niger, Nigeria, Chad, and Cameroon, as well as a diaspora community residing in Sudan. Those generally termed Kanuri include several subgroups and dialect groups, some of whom identify as distinct from the Kanuri. Most trace their origins to ruling lineages of the medieval Kanem–Bornu Empire, and its client states or provinces. In contrast to the neighboring Toubou or Zaghawa pastoralists, Kanuri groups have traditionally been sedentary, engaging in farming, fishing the Chad Basin, trade, and salt processing.
