The Suez Canal Crisis of 1956 was a pivotal conflict that erupted after Egyptian Prime Minister Gamal Abdel Nasser nationalized the canal, leading to a military response from Britain, France, and Israel. This international confrontation highlighted the rising assertiveness of Third World nations and showcased the willingness of the United States and the USSR to intervene to maintain stability. Ultimately, a UN peacekeeping force was established, restoring Egyptian control and marking a significant shift in post-colonial geopolitics.
