The famous British Prime Minister during the Suez Crisis was Anthony Eden. The crisis began in 1956 when Egypt's President Gamal Abdel Nasser nationalized the Suez Canal, previously controlled by British and French interests. Eden, who had supported military intervention alongside France and Israel to regain control of the Canal, faced international backlash, particularly from the United States and the United Nations. As a result, the military operation ended in failure, leading to a loss of British influence in the Middle East and marking a significant shift in post-war geopolitics. The crisis also contributed to Eden’s political decline and resignation in early 1957.
