The 1979 Iranian Revolution inspired other Islamist movements and alarmed Sunni governments

See a timeline of the events that shaped the Iranian Revolution

From a defamatory newspaper editorial that sparked protests in January 1978 to Khomeini's return from exile and the Shah's flight from Iran in 1979, this timeline traces the rapidly escalating chain of events—protests, crackdowns, and political collapses—that toppled one of the Middle East's most powerful monarchies.

The Sunni-Shia divide has fueled conflict and rivalry throughout the Middle East for centuries

Iranians voted overwhelmingly to establish an Islamic Republic in March 1979

Just weeks after Khomeini's return, Iran held a national referendum to replace the monarchy with an Islamic Republic, and over 98% voted in favor (though the vote was criticized).

Iran became a constitutional monarchy in 1906

The Iranian Revolution relied largely on nonviolent tactics

Despite thousands of unarmed protesters killed by the Shah's forces, the revolution relied overwhelmingly on nonviolent tactics, including strikes, demonstrations, and civil disobedience, with up to 9 million Iranians peacefully taking to the streets, making it one of history's largest protest movements by population percentage.

Ayatollah Khomeini led the ideological opposition to the Shah from exile

Exiled in 1964 for opposing a law that granted diplomatic immunity to US military personnel in Iran, Khomeini built a large following by smuggling recorded sermons into Iran on cassette tapes. He aimed to replace the monarchy with an Islamic republic governed by religious law.

'Velayat-e faqih' is the religious doctrine that has governed Iran since the 1979 revolution

Meaning "guardianship of the Islamic jurist," the doctrine transfers all political and religious authority to the Shia clergy, with the supreme leader holding ultimate power over the state. Developed by Khomeini in the 1970s, it has served as the foundation of Iran's government since the revolution.

Iran's Revolutionary Guard Corps became one of the most powerful forces in the Middle East

Created after the 1979 revolution to protect the new Islamic Republic, the IRGC grew into a force that controls Iran's ballistic missile arsenal, funds, and arms regional proxy groups such as Hezbollah and Hamas, and answers directly to the supreme leader.

Iran's Revolutionary Guard Corps is independent of Iran's regular army and is one of the most powerful and influential military-political organizations in the Middle East.
