AP WAS THERE: A 1953 CIA-led coup in Iran topples prime minister, cements shah’s power

EDITOR'S NOTE — In August 1953, a CIA-backed coup toppled Iran's prime minister, cementing the rule of Shah Mohammad Reza Pahlavi for over 25 years before the 1979 Islamic Revolution. The coup, carried out by allied members of its military and security forces, came after then-Prime Minister Mohammad Mossadegh had nationalized the country's oil industry. At the time, Iran's Abadan refinery was the largest in the world and a key supply for Britain, which backed the coup to regain its access.
