Anglo-Egyptian Sudan was a condominium of the United Kingdom and Egypt between 1899 and 1956, corresponding mostly to the territory of present-day South Sudan and Sudan. Legally, sovereignty and administration were shared between both Egypt and the United Kingdom, but in practice the structure of the condominium ensured effective British control over Sudan, with Egypt having limited local power and influence. In the meantime, Egypt itself fell under increasing British influence. Following the Egyptian Revolution of 1952, Egypt pushed for an end to the condominium, and the independence of Sudan. By agreement between Egypt and the United Kingdom in 1953, Sudan was granted independence as the Republic of the Sudan on 1 January 1956. In 2011, the south of Sudan itself became independent as the Republic of South Sudan.

The Kingdom of Egypt was the legal form of the Egyptian state during the latter period of the Muhammad Ali dynasty's reign, from the United Kingdom's recognition of Egyptian independence in 1922 until the abolition of the monarchy of Egypt and Sudan in 1953 following the Egyptian Revolution of 1952. Until the Anglo-Egyptian treaty of 1936, the Kingdom was only nominally independent, as the United Kingdom retained control of foreign relations, communications, the military, and Sudan. Officially, Sudan was governed as a condominium of the two states; however, in reality, true power in Sudan lay with the United Kingdom. Between 1936 and 1952, the United Kingdom continued to maintain its military presence, and its political advisers, at a reduced level, which resulted in the increase of Egyptian sovereignty and independence.
