Anglo-Soviet invasion of Iran

The Anglo-Soviet invasion of Iran in 1941 was a military campaign by Britain and the Soviet Union to secure Iran during World War II. They aimed to ensure supply routes for their troops fighting in the Middle East and to prevent Iran from falling under Nazi influence. The invasion involved Allied forces quickly crossing into Iran, prompting the Iranian government to surrender. As a result, Iran's strategic resources and railway lines were controlled by the Allies. The invasion was controversial, affecting Iran's sovereignty, but it was primarily motivated by wartime security concerns.
