King of Egypt and the Sudan (Arabic: ملك مصر والسودان‎‎ Malik Miṣr was-Sūdān) was the title used by the Egyptian monarch from 16 October 1951 until the abolition of the monarchy on 18 June 1953. In 1951, the Egyptian Parliament amended the Constitution by Law 176 of 16 October 1951 to provide that the title of the King should be "King of Egypt and the Sudan" instead of "King of Egypt, Sovereign of Nubia, Sudan, Kordofan, and Darfur". This move came in the wake of Wafdist Prime Minister Nahhas Pasha's decision to unilaterally abrogate the Anglo-Egyptian Treaty of 1936. The change in King Farouk I's title was intended to further Egypt's claims over the Sudan, which had been an Anglo-Egyptian condominium since 1899.
