We look at the 70th anniversary of the August 19, 1953, U.S.- and U.K-backed coup in Iran, which took place two years after Iran’s democratically elected Prime Minister Mohammad Mosaddegh nationalized Iran’s oil industry that had been controlled by the company now known as British Petroleum. “If nationalization in Iran of oil was successful, this would set a terrible example to other countries where U.S. oil interests were present,” explains Ervand Abrahamian, Iranian historian and author of Oil Crisis in Iran: From Nationalism to Coup d’Etat and The Coup: 1953, The CIA, and the Roots of Modern U.S.-Iranian Relations. While the CIA has historically taken credit for Mosaddegh’s overthrow, “the British have not admitted their leading role,” notes Iranian filmmaker Taghi Amirani, whose documentary film Coup 53 uncovers the influence of MI6 agents who sought to preserve their imperial-era access to Iranian oil and pulled in the Americans by promising a “slice.” Seventy years later, says Amirani, “We are still living with the ripples of this disastrous event.”
