In late 1956, the nationalization of the Suez Canal by Egyptian President Gamal Abdel Nasser set off a geopolitical crisis that drew in Britain, France, and Israel. They orchestrated a military intervention to regain control of the canal, which had been a vital link for British and French trade and colonial interests in the region. The ensuing warfare drew international outrage, particularly from both the United States and the Soviet Union, who saw it as an act of imperialism. The military campaign, particularly its rapid onset and execution, was met with fierce resistance from Egyptian forces and revealed the declining power of Britain on the world stage. Sir Anthony Eden advocated for the intervention, but the backlash against the decision was severe. Public opinion shifting against the war efforts, compounded by economic pressures and diplomatic isolation, forced the British government into a retreat from the canal. Ultimately, Eden, who had staunchly supported the intervention, faced mounting pressure from his party and the public, leading him to announce his resignation in January 1957. His departure marked a significant shift in British politics and indicated the end of an era of imperialism.
