The Egyptian Revolution of 1952 (ثورة 23 يوليو 1952), also known as the 1952 Coup d'état (انقلاب 1952) and 23 July Revolution, was a period of profound political, economic, and societal change in Egypt. On 23 July 1952 the revolution began with the toppling of King Farouk in a coup d'état by the Free Officers Movement. This group of army officers was led by Mohamed Naguib and Gamal Abdel Nasser. The Revolution ushered in a wave of revolutionary politics in the Arab World, and contributed to the escalation of decolonisation, and the development of Third World solidarity during the Cold War. Though initially focused on grievances against King Farouk, the movement had more wide-ranging political ambitions. In the first three years of the Revolution, the Free Officers moved to abolish the constitutional monarchy and aristocracy of Egypt and Sudan, establish a republic, end the British occupation of the country, and secure the independence of Sudan (previously governed as an condominium of Egypt and the United Kingdom). The revolutionary government adopted a staunchly nationalist, anti-imperialist agenda, which came to be expressed chiefly through Arab nationalism, and international non-alignment. The Revolution was faced with immediate threats from Western imperial powers, particularly the United Kingdom, which had occupied Egypt since 1882, and France, both of whom were wary of rising nationalist sentiment in territories under their control throughout Africa, and the Arab World. The ongoing state of war with the State of Israel also posed a serious challenge, as the Free Officers increased Egypt's already strong support of the Palestinians. These two issues converged in the fifth year of the Revolution when Egypt was invaded by the United Kingdom, France, and the State of Israel in the Suez Crisis of 1956 (known in Egypt as the Tripartite Aggression). Despite enormous military losses, the war was seen as a political victory for Egypt, especially as it left the Suez Canal in uncontested Egyptian control for the first time since 1875, erasing what was seen as a mark of national humiliation.
