The country's pro-Axis allegiance in World War II led to Anglo-Russian occupation of Iran in 1941 and deposition of the shah in favor of his son, Mohammed Reza Pahlavi. Pahlavi's Westernization programs alienated the clergy, and his authoritarian rule led to massive demonstrations during the 1970s, to which the shah responded with the imposition of martial law in Sept. 1978. The shah and his family fled Iran on Jan. 16, 1979, and the exiled cleric Ayatollah Ruhollah Khomeini returned to establish an Islamic theocracy. Khomeini proceeded with his plans for revitalizing Islamic traditions. He urged women to return to wearing the veil; banned alcohol, Western music, and mixed bathing; shut down the media; closed universities; and eliminated political parties.
