Suez Crisis: The United Kingdom and France begin bombing Egypt to force the reopening of the Suez Canal.

The Suez Crisis, also known as the second Arab–Israeli war, the Tripartite Aggression in the Arab world and the Sinai War in Israel, was a British–French–Israeli invasion of Egypt in 1956. Israel invaded on 29 October, having done so with the primary objective of re-opening the Straits of Tiran and the Gulf of Aqaba as the recent tightening of the eight-year-long Egyptian blockade further prevented Israeli passage. After issuing a joint ultimatum for a ceasefire, the United Kingdom and France joined the Israelis on 5 November, seeking to depose Egyptian president Gamal Abdel Nasser and regain control of the Suez Canal, which Nasser had earlier nationalised by transferring administrative control from the foreign-owned Suez Canal Company to Egypt's new government-owned Suez Canal Authority. Shortly after the invasion began, the three countries came under heavy political pressure from both the United States and the Soviet Union, as well as from the United Nations, eventually prompting their withdrawal from Egypt. The Crisis demonstrated that the United Kingdom and France could no longer pursue their independent foreign policy without consent from the United States. Israel's four-month-long occupation of the Egyptian-occupied Gaza Strip and Egypt's Sinai Peninsula enabled it to attain freedom of navigation through the Straits of Tiran, but the Suez Canal was closed from October 1956 to March 1957.

The Republic of Egypt was a state created in 1953 under the rule of Mohammed Naguib following the Egyptian revolution of 1952 in which the Kingdom of Egypt's Muhammad Ali dynasty came to an end. It was superseded in 1958 with the creation of the United Arab Republic.

The Suez Canal is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. It is the border between Africa and Asia. The 193.30-kilometre-long (120.11 mi) canal is a key trade route between Europe and Asia.
