The Egyptian Revolution of 1919 ( Thawra 1919) was a countrywide revolution against the British occupation of Egypt and Sudan. It was carried out by Egyptians from different walks of life in the wake of the British-ordered exile of the revolutionary Egyptian Nationalist leader Saad Zaghlul, and other members of the Wafd Party in 1919. The revolution led to the United Kingdom's later recognition of Egyptian independence in 1922 as the Kingdom of Egypt, and the implementation of a new constitution in 1923. The British government, however, refused to recognise full Egyptian sovereignty over Sudan, or to withdraw its forces from the Suez Canal Zone, factors that would continue to sour Anglo-Egyptian relations in the decades leading up to the Egyptian revolution of 1952. Background The Ottoman Empire retained nominal sovereignty over Egypt, but the political connection between the two countries was largely severed by the earlier seizure of power by Muhammad Ali in 1805, and re-enforced by the later increasing British influence and occupation of Egypt in 1882. From 1883 to 1914, the Khedive of Egypt and Sudan under the Ottoman Sultan remained the official ruler of the country, but ultimate power was exercised by the British Consul-General.

On 14 December 1914, the Khedivate of Egypt was elevated to a separate level of Sultanate of Egypt, and declared as a British protectorate, thus terminating definitively the legal fiction of Ottoman sovereignty over its province of Egypt. The terms of the protectorate led Egyptian nationalists to believe that it was a temporary arrangement that would be changed after the world war through bilateral agreement with Britain. Causes Before World War I, nationalist agitation was limited to the educated elite. During the war, however, dissatisfaction with the British occupation spread among all classes of the population, a result of Egypt's increasing involvement in the war despite Britain's promise to shoulder the entire burden. During the war, the British government stationed thousands of imperial troops in Egypt, conscripted over one and a half million Egyptians into the Labour Corps, and requisitioned buildings, supplies and animals fight on different fronts for use in the war effort. In addition, because of Allied promises during the war (such as
