Who was involved in the war over the Suez Canal in 1956?

The 1956 Suez Crisis involved Egypt, led by President Gamal Abdel Nasser, and a coalition of the United Kingdom, France, and Israel. The conflict arose when Nasser nationalized the Suez Canal, previously controlled by British and French interests, prompting the invasion by the three countries. The United States and the Soviet Union played significant roles in diplomatic negotiations, ultimately leading to the withdrawal of invading forces and reinforcing Egypt's control over the canal.
