The Tuareg (also spelled Twareg or Touareg; endonym Imuhagh) are Berber people with a traditionally nomadic pastoralist lifestyle. They are the principal inhabitants of the Saharan interior of North Africa. The Tuareg language, a branch of the Berber languages, has an estimated 1.2 million speakers. About half this number is accounted for by speakers of the Eastern dialect (Tamajaq, Tawallammat). Most Tuareg live in the Saharan parts of Niger, Mali, and Algeria. Being nomadic, they move constantly across national borders, and small groups of Tuareg also live in southeastern Algeria, southwestern Libya and northern Burkina Faso, and a small community in northern Nigeria.
