Through this coup, code-named Operation TP-Ajax, Mossadegh was deposed and a new government was installed in August 1953. The new leader was a member of Iran’s royal family named Mohammed Reza Shah Pahlavi. The Shah’s government was secular, anti-communist and pro-Western. In exchange for tens of millions of dollars in foreign aid, he returned 80 percent of Iran’s oil reserves to the Americans and the British.
