The continued agitation within Egypt as a result of British control led to a series of revolts where British military outposts were attacked. From 1950–52, workers in the Suez Canal Zone went on strike but were blockaded by British tanks. The government in Cairo warned nationalists not to interfere in public spaces that are associated with imperialism. Contrarily, attacks were made against the British and the Egyptian elites who worked with them. At this point, Egyptian nationalist groups were divided and unorganised. The military was the only area that still held some sort of organised mission, which led to the Revolution of 1952. The revolutionaries publicised the need for reform and social justice, marched on Cairo and forced King Farouk to abdicate his throne. The Revolution proved crucial in ending the British occupation of Egypt and Sudan, which had commenced in 1882.
