Darfur is a region of western Sudan. Dār is an Arabic word meaning "home [of]" – the region was named Dardaju while ruled by the Daju, who migrated from Meroë c. 350 AD, and it was renamed Dartunjur when the Tunjur ruled the area. Darfur was an independent sultanate for several hundred years until 1874, when it fell to the Sudanese warlord Rabih az-Zubayr. The region was later invaded and incorporated into Sudan by Anglo-Egyptian forces in 1916. As an administrative region, Darfur 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 and genocide since 2003. The factors include religious and ethnic rivalry, and the rivalry between farmers and herders.

It has a population of 45.7 million people as of 2022 and occupies 1,886,068 square kilometres, making it Africa's third-largest country by area and the third-largest by area in the Arab League.
