Mohammad Reza Pahlavi (b. 26 October 1919, Tehran, Persia–d. 27 July 1980, Cairo, Egypt) was the last Shah of Iran from Sept. 1941 until Feb. 11, 1979 (the Iranian Revolution). He replaced his father as Shah after British and Soviet forces forced his father to abdicate during World War II. Mohammad Reza Pahlavi made changes to modernize Iran during the White Revolution in the 1960s. However, he lost support from clergy and working class due to his modernization, relations with Israel, and corruption issues. He died in exile in Egypt.
