The Sultanate of Darfur was a pre-colonial state in present-day Sudan. It existed from 1603 to October 24, 1874, when it fell to the Sudanese warlord Rabih az-Zubayr and again from 1898 to 1916, when it was conquered by the British and integrated into Anglo-Egyptian Sudan. At its peak in the late 18th and early 19th century it stretched all the way from Darfur in the west to Kordofan and the western banks of the White Nile in the east, giving it the size of present-day Nigeria.
