Mohammad Reza Pahlavi

FILE - In this Feb. 16, 1950 file photograph, the Shah of Iran Mohammad Reza Pahlavi reads his inaugural speech at the initial session of his nation's first senate in Tehran, Iran. The U.S. ambassador to Iran mistakenly told the shah in 1953 that Britain's newly enthroned Queen Elizabeth II backed a plan to overthrow the country's elected prime minister and America maintained the fiction even after realizing the error, historians now say.
