1979-2002: Islamic fundamentalism takes hold in Iran.
Under the Ayatollah Khomeini, law codes based on Islam are introduced in Iran, ending the Shah's radical modernization policies. Khomeini's strict version of Islamic religious standards become the law of everyday life. Some Iranians are upset by the strict religious system. Many people who accepted Western cultural influences leave Iran, including most Jews and Christians. The "Islamicization" of the government continues into the 21st century.
