intents and purposes, the Sultanate of Egypt was as much controlled by the United Kingdom as the Khedivate of Egypt had been. Rising nationalist anger at British control led to the Egyptian Revolution of 1919, prompting the United Kingdom to recognise Egyptian independence in 1922 as the Kingdom of Egypt. Egyptian nationalists, and Sudanese favouring union with Egypt, demanded that Sudan be included within the bounds of the kingdom, with the term "Kingdom of Egypt and Sudan" entering the nationalist vernacular. However, in the terms of the legal instrument by which the United Kingdom recognised Egyptian independence, it specifically reserved the issue of the governance of Sudan as a question to be resolved in the future. Defying Egyptian and Sudanese demands, the United Kingdom gradually assumed more control of the condominium, edging out Egypt almost completely by 1924. In the decades that followed, Egyptian and Sudanese discontent and anger at continued British rule in Sudan increased. On 16 October 1951, the Egyptian government abrogated the agreements underpinning the condominium, and declared that Egypt and Sudan were legally united as the Kingdom of Egypt and Sudan, with King Farouk as the King of Egypt and the Sudan. This was superseded by the Egyptian Revolution of 1952 eight months later, which overthrew King Farouk. The new revolutionary government under Muhammad Naguib and Gamal Abdel Nasser made Sudanese independence a priority. Naguib himself was half-Sudanese, and had been born and raised in Khartoum. Under continued pressure, the United Kingdom conceded to Egypt's demands in 1953, with the governments of both Egypt and the United Kingdom agreeing to terminate the condominium, and grant Sudan independence in 1956. On 1 January 1956, Egyptian and British sovereignty over Sudan duly ended, and Sudan became independent. Background Union with Egypt In 1820, the army of Egyptian wāli Muhammad Ali Pasha, commanded by his son Ismail Pasha, gained control of Sudan. The region had longstanding linguistic, cultural, religious, and economic ties to Egypt, and had been partially under the same government at intermittent periods since the times of the pharaohs. Muhammad Ali was aggressively pursuing a policy of expanding his power with a view to possibly supplanting the Ottoman Empire (to which he technically owed fealty), and saw Sudan as a valuable addition to his Egyptian dominion. During his reign and that of his successors, Egypt and Sudan came to be administered as one political entity, with all
