Mossadegh's liberal and independent way of governing gained him the popular support but also alienated various groups. It entered in direct conflict with the Western interests in the region, challenged the shah's authority and Mossadegh's tolerance with lefties groups offended the traditionalist and the ulama. In favour of strengthening the monarchical rule of Mohammad Reza Pahlavi, Winston Churchill and the Eisenhower administration decided to overthrow Iran's government, though the predecessor Truman administration had opposed a coup. Mosaddegh was removed from power in a coup on 19 August 1953, organised and carried out by the CIA at the request of MI6, which chose Iranian General Fazlollah Zahedi to succeed Mosaddegh.
