The Muhammad Ali dynasty was the ruling dynasty of Egypt and Sudan from the 19th to the mid-20th century. It is named after its progenitor, Muhammad Ali Pasha, regarded as the founder of modern Egypt. It was also more formally known as the Alawiyya or Alawite dynasty in contemporary English, and as Al-Usra al-Alawiyya ( ) in Arabic. Because a majority of the rulers from this dynasty bore the title Khedive, it was often referred to by contemporaries as the Khedival dynasty.

The Egyptian Revolution of 1952 (Arabic: ثورة 23 يوليو 1952), also known as the 23 July Revolution, was a period of profound political, economic, and societal change in Egypt that began on 23 July 1952 with the toppling of King Farouk in a coup d'etat by the Free Officers Movement, a group of army officers 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. This strengthened the appeal of the revolution in other Arab countries.

Wholesale agrarian reform, and huge industrialisation programmes were initiated in the first decade and half of the Revolution, leading to an unprecedented period of infrastructure building, and urbanisation. 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 MENA region.

The Revolution is commemorated each year on 23 July.
