The Sultanate of Darfur was a pre-colonial state in present-day Sudan. It existed from 1603 to 24 October 1874, when it fell to the Sudanese warlord Rabih az-Zubayr, and again from 1898 to 1916, when it was occupied by the British and the Egyptians and was 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.

Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Egypt to the north, Eritrea to the northeast, Ethiopia to the southeast, Libya to the northwest, South Sudan to the south, and the Red Sea. 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. It was the largest country by area in Africa and the Arab League until the secession of South Sudan in 2011; since then both titles have been held by Algeria. Its capital and most populous city is Khartoum.
