The Suez Crisis, also named the Tripartite Aggression and the Kadesh Operation, was an invasion of Egypt in late 1956 by Israel, followed by the United Kingdom and France. The aims were to regain Western control of the Suez Canal and to remove Egyptian President Gamal Abdel Nasser from power. After the fighting had started, the United States, the Soviet Union, and the United Nations forced the three invaders to withdraw. The episode humiliated Great Britain and France and strengthened Nasser.
As a result of the conflict, the United Nations created the United Nations Emergency Force/UNEF Peacekeepers to police the Egyptian–Israeli border, British Prime Minister Anthony Eden resigned, Canadian Minister of External Affairs Lester Pearson won the Nobel Peace Prize, and the USSR may have been emboldened to invade Hungary.
