The Egyptian revolution of 1952, also known as the 1952 coup d'état (Arabic: انقلاب 1952) and the 23 July Revolution (Arabic: ثورة 23 يوليو), 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, a group of army officers led by Mohamed Naguib and Gamal Abdel Nasser. It ushered in a wave of revolutionary politics in the Arab world, and contributed to the escalation of decolonization, 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 a 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 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 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. This strengthened the appeal of the revolution in other Arab countries.

Wholesale agrarian reform, and large-scale industrialization programs were initiated in the first decade and half of the revolution, leading to an unprecedented period of infrastructure building, and urbanization. By the 1960s, Arab socialism had become a dominant theme, transforming Egypt into a centrally planned economy. Official fear of a Western-sponsored counter-revolution, domestic religious extremism, potential communist infiltration, and the conflict with the State of Israel were all cited as reasons compelling severe and longstanding restrictions on political opposition, and the prohibition of a multi-party system. These restrictions on political activity would remain in place until the presidency of Anwar Sadat from 1970 onwards, during which many of the policies of the Revolution were scaled back or reversed.

The early successes of the revolution encouraged numerous other nationalist movements in other countries, such as Algeria, where there were anti-imperialist and anti-colonial rebellions against European empires. It also inspired the toppling of existing pro-Western monarchies and governments in the Middle East and North Africa. The revolution is commemorated each year on 23 July.

The history of Egypt during the 19th and early 20th centuries was defined by the vastly different reigns of successive members of the Muhammad Ali dynasty and the gradually increasing intrusion into Egyptian affairs of the great powers, particularly the United Kingdom and France. From 1805, Egypt underwent a period of rapid modernisation under Muhammad Ali Pasha, who declared himself Khedive in defiance of his nominal suzerain, the Ottoman Sultan. Within a matter of decades, Muhammad Ali transformed Egypt from a neglected Ottoman province to a virtually independent state that temporarily rivalled the Ottoman Empire for dominance in the Eastern Mediterranean and the Mashriq. Muhammad Ali conquered the Sudan, invaded East Africa, and led Egypt during both the First Egyptian–Ottoman War and the Second Egyptian–Ottoman War, triggering the Oriental Crisis. As a result of these wars, Egypt was expelled from the Levant, but allowed to keep its Sudanese territory. After Muhammad Ali's death, his successors Abbas I and Sa'id attempted to modernize Egypt, starting construction of the Suez Canal. Due to conscription, taxes were raised on nobles in exchange for more land and peasants (fellahin in Arabic). Peasants continued to lose access to their land as cotton became a major cash crop in Egypt.

Under Isma'il the Magnificent, Egypt went through massive modernization programmes and campaigns of military expansion in Sudan and East Africa. Isma'il greatly accelerated the enfranchisement of the Egyptian peasantry and middle class, who had been politically and economically marginalized by the wealthy elites of Egyptian society. It was during this time that an Egyptian intelligentsia was formed, a social class of educated Egyptians well-read in politics and culture known as the Effendi. Under the education minister Ali Pasha Mubarak, the public education system in Egypt grew the field of educated nationalist effendiyya. It was during this time that Italians, Greeks, French, Armenians, Jews, and other groups immigrated to Egypt, establishing a small but wealthy and politically powerful cosmopolitan community. Foreigners were not subject to Egyptian laws, but went through a separate court system known as the Mixed Courts. Isma'il also established Egypt's first parliament. This period of intellectualism in Egypt, and the Arab world as a whole, later became known as the Nahda. Coupled with Isma'il's powerful espousal of Egyptian statehood, this contributed to the growth of Egyptian nationalism, particularly within the army. However, the war with Ethiopia ended in disaster, further exasperating the Egyptian treasury. The Caisse de la Dette Publique (Public Debt Commission) was founded as a way for Egypt to pay its debts.

Isma'il's grand policies were ruinously expensive, and financial pressure eventually compelled him to sell Egypt's shares in the Universal Company of the Maritime Canal of Suez, the company that owned the 99-year lease to manage the Suez Canal. The sale of the Canal mere years after it had been constructed at the cost of some 80,000 Egyptian lives was seen as a national humiliation, particularly as it effectively granted the purchaser, the United Kingdom, a basis for interfering in Egyptian affairs. Shortly thereafter, the United Kingdom, along with the other Great Powers, deposed Isma'il in favour of his son, Tewfik Pasha.
