Darfur ( , ) is a region in western Sudan. It was firstly named Dardaju when the Daju, who migrated from Meroe c.350 AD, were ruling. Then renamed Dartunjur when the Tunjur were ruling the country and who had been replaced by the Fur recent immigrants from Dar Fartit in the Central Africa. Darfur (Dar in the name means 'place of or land of' the Fur people) was a independent sultanate for several hundred years, incorporated into Sudan by Anglo-Egyptian forces in 1916. The region is divided into five federal states: Central Darfur, East Darfur, North Darfur, South Darfur and West Darfur. Because of the war in Darfur between Sudanese government forces and the indigenous population, the region has been in a state of humanitarian emergency since 2003.
