Sultanate of Darfur
The Sultanate of Darfur was a pre-colonial state in present-day Sudan. It existed from the 16th century to 1874, when it fell to the Sudanese warlord Al-Zubayr Rahma Mansur, and was re-established again from 1898 to 1916, until it was conquered by the British. 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.
