The history of Egypt under the British lasted from 1882, when it was occupied by British forces during the Anglo-Egyptian War, until 18 June 1956, when the last British forces withdrew in accordance with the Anglo-Egyptian evacuation agreement of 1954. The first period of British rule (1882–1914) is often called the "veiled protectorate". During this time the Khedivate of Egypt remained an autonomous province of the Ottoman Empire, and the British occupation had no legal basis but constituted a de facto protectorate over the country. Egypt was thus not part of the British Empire. This state of affairs lasted until 1914 when the Ottoman Empire joined World War I on the side of the Central Powers and Britain declared a protectorate over Egypt. The ruling khedive, Abbas II, was deposed and his successor, Hussein Kamel, compelled to declare himself Sultan of Egypt independent of the Ottomans in December 1914.
