Mohammad Reza Pahlavi was the last Shah of Iran, ruling from 1941 until his overthrow in the Iranian Revolution of 1979. His reign was marked by significant modernization efforts, Westernization, and increasing authoritarianism, which ultimately contributed to widespread discontent and the 1979 revolution that led to the establishment of the Islamic Republic of Iran. His connection to U.S. foreign policy is highlighted by the Camp David Accords and the Iran Hostage Crisis, both of which shaped U.S.-Middle Eastern relations during this period.
