Baggāra in Sudan, also known as Shuwa/Diffa Arabs in Chad and West Africa, derives from Arabic word (Arabic: بقارة‎) literally means "Cowman", are a set of communities and/or coalition of many other inhabiting the portion of Africa's Sahel mainly between Lake Chad and southern Kordofan, numbering over one million. They have a common language which is one of the regional colloquial Arabic languages. They also have a common traditional mode of subsistence, nomadic cattle herding, although nowadays many lead a settled existence. Nevertheless, collectively they do not all necessarily consider themselves one people, i.e., a single ethnic group. The term "baggara culture" was introduced in 1994 by Braukämper. The political use of term "baggara" in Sudan denote a particular set of tribes is limited to Sudan;It often means a coalition of majority Black tibes (mainly Fur, Nuba and Fallata) with other Arab tribes of western part of Sudan (mainly Guhayna), as oppose to Bedouin Abbala Arab tribes, and sometimes Baggara and Fallata known as Gharraba Arabic: غرابة‎ means Westerner (Western Of Sudan) .^{[citation needed]} The bulk of so called "baggara Arabs" live in Chad. The rest live, or seasonally migrate to, southwest Sudan (specifically the southern portions of Darfur and Kordofan),and slivers of the Central African Republic, South Sudan, and Niger. Those who are still nomads migrate seasonally between grazing lands in the wet season and river areas in the dry season.
