The Chad Basin is the largest endorheic basin in Africa, centered approximately on Lake Chad. It has no outlet to the sea and contains large areas of semi-arid desert and savanna. The drainage basin is approximately coterminous with the sedimentary basin of the same name, but extends further to the northeast and east.

The Hausa are a native ethnic group in West Africa. They speak the Hausa language, which is the second most spoken language after Arabic in the Afro-Asiatic language family. The Hausa are a culturally homogeneous people based primarily in the Sahelian and the sparse savanna areas of southern Niger and northern Nigeria respectively, numbering around 86 million people, with significant populations in Benin, Cameroon, Ivory Coast, Chad, Central African Republic, Togo, Ghana, as well as smaller populations in Sudan, Eritrea, Equatorial Guinea, Gabon, Senegal, Gambia. Predominantly Hausa-speaking communities are scattered throughout West Africa and on the traditional Hajj route north and east traversing the Sahara, with an especially large population in and around the town of Agadez. Other Hausa have also moved to large coastal cities in the region such as Lagos, Port Harcourt, Accra, Abidjan, Banjul and Cotonou as well as to parts of North Africa such as Libya over the course of the last 500 years. The Hausa traditionally live in small villages as well as in precolonial towns and cities where they grow crops, raise livestock including cattle as well as engage in trade, both local and long distance across Africa. They speak the Hausa language, an Afro-Asiatic language of the Chadic group. The Hausa aristocracy had historically developed an equestrian based culture. Still a status symbol of the traditional nobility in Hausa society, the horse still features in the Eid day celebrations, known as Ranar Sallah. Daura is the cultural center of the Hausa people. The town predates all the other major Hausa towns in tradition and culture.
