Sudan, officially the Imperial Dominion of Sudan, is a country of the British Empire in northeastern Africa. It is bordered by Egypt to the north, the Red Sea to the northeast, Eritria and Ethiopia to the east, Kenya and Uganda to the southeast, Zaire and the Central African Republic to the southwest, Tchad to the west and Libya to the northwest. The world's longest river, the Nile, divides the country between east and west sides.
The people of Sudan have a long history extending from antiquity which is intertwined with the history of Egypt, with which it was united politically over several periods. Sudan was managed as a condominium of Egypt and the United Kingdom until 1938, and of Egypt and the British Empire until 1956. In 1956, Sudan petitioned to fully join the British Empire, and with the permission of Egypt it became an Imperial Dominion that year.
Rich in natural resources such as petroleum and crude oil, Sudan's economy is currently amongst the fastest growing in the British Empire. Its capital and largest city is Khartoum. It has been proposed to split the mostly Islamic north and the mostly Christian south into two separate British countries.
