The Convention of Constantinople in 1888 declared the canal a neutral zone under the protection of the British, who had occupied Egypt and Sudan at the request of Khedive Tewfiq to suppress the Urabi Revolt against his rule. The revolt went on from 1879 to 1882. As a result of British involvement on the side of Khedive Tewfiq, Britain gained control of the canal in 1882. The British defended the strategically important passage against a major Ottoman attack in 1915, during the First World War. Under the Anglo - Egyptian Treaty of 1936, the UK retained control over the canal. The canal was again strategically important in the 1939 -- 1945 Second World War, and Italo - German attempts to capture it were repulsed during the North Africa Campaign, during which the canal was closed to Axis shipping. In 1951 Egypt repudiated the treaty and in October 1954 the UK agreed to remove its troops. Withdrawal was completed on 18 July 1956.
