Britain, resentful of the nationalization of Iran`s oil industry, came up with the idea for the coup in 1952 and pressed the U.S. to mount a joint operation to remove the democratically elected government of Prime Minister Mohammed Mossadegh and install the Shah Mohammed Reza Pahlavi to rule Iran autocratically. Partially due to fear of a Communist overthrow due to increasing influence of the Communist Tudeh party, and partly to gain control of a larger share of Iranian oil supplies, the US agreed. Brigadier General Norman Schwarzkopf, Sr. and CIA guru Kermit Roosevelt, Jr. were ordered to begin a covert operation to overthrow Mossadegh. A complex plot, codenamed Operation Ajax, was conceived and executed from the US Embassy in Tehran. Full details of the operation were released fifty years later, in 2003. Britain, who previously had controlled all of the Iranian oil industry, lost its monopoly and allowed U.S. oil companies to compete in Iran.
