The Shah fled Iran in January 1979, ending nearly 38 years of Pahlavi rule

Mohammad Reza Shah Pahlavi ruled Iran for nearly four decades before being ousted by the revolution

The last Shah of Iran came to power in 1941 and pursued rapid Westernization through his controversial reforms. His authoritarian rule, backed by the US, and his feared secret police, SAVAK, fueled mass resentment that ultimately drove him from power in 1979.

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.

Ayatollah Khomeini returned to Iran on Feb. 1, 1979, after 14 years in exile

Greeted by millions of Iranians flooding the streets of Tehran, Khomeini's return was a defining moment of the revolution. Within days, he appointed a rival prime minister, effectively dismantling the last remnants of the Shah's government and consolidating clerical rule over the new Islamic Republic.

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.

Mohammad Mosaddegh was ousted in a CIA-backed coup in 1953

Iran's democratically elected prime minister, Mosaddegh, nationalized the country's oil industry in 1951, challenging British and American control of Iran's resources. The CIA and British intelligence orchestrated a coup that ousted him and reinstated the Shah, fueling decades of Iranian distrust of the West.

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). The vote formalized the revolution's outcome, laying the foundation for a theocratic government that remains in place today.

Persia was officially called Iran by the international community in 1935

At the request of Reza Shah, the international community began using "Iran"—the name Iranians had always called their country—replacing the Western term "Persia." The change reflected a broader push for national identity and modernization under the Pahlavi dynasty.

In 1979, Iranian students seized the US Embassy in Tehran, holding 52 Americans hostage for 444 days

Outraged by the US decision to allow the exiled Shah to enter the United States for medical treatment, student protesters stormed the embassy in November 1979. The crisis paralyzed the Carter presidency and ended with a negotiated release on the day of Ronald Reagan's inauguration.

Iran became a constitutional monarchy in 1906

A popular revolution forced the ruling Qajar Shah—a dynasty that had governed Iran since the late 18th century—to sign a constitution and establish a parliament, marking Iran's first major step toward democratic governance and limiting the monarchy's absolute power.

The Shah used torture and other human rights abuses to maintain power before the revolution

A declassified 1976 US Embassy telegram acknowledged that the Shah held 3,400-3,500 political prisoners, documented torture allegations against the SAVAK secret police, and confirmed press censorship, even as American diplomats sought to minimize human rights concerns for Congress.

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 Khamenei ruled Iran for 36 years after succeeding Khomeini as Supreme Leader

When Khomeini died in 1989, Ali Khamenei was appointed acting supreme leader on the same day. He served in this position until his death in February 2026, shaping Iran for nearly four decades.

Iraq invaded Iran in 1980, drawing the new Islamic Republic into a devastating eight-year war

Just a year after the revolution, Saddam Hussein invaded Iran, hoping to exploit its post-revolutionary instability. The brutal conflict killed hundreds of thousands in one of the century's deadliest conflicts and forced Khomeini's government to consolidate power.

'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.

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

By establishing the world's first modern Islamic theocracy, the revolution inspired Islamist movements across the region and alarmed Sunni Arab governments. The resulting rivalry between Shia Iran and Sunni Saudi Arabia has since fueled proxy conflicts in Lebanon, Iraq, Syria, and Yemen that persist today.

Mosaddegh nationalized Iran's oil industry in 1951, threatening Western control of the country's resources

Before nationalization, British companies controlled most of Iran's oil wealth, with little revenue returned to Iranians. Mosaddegh's decision made him a national hero at home but triggered a Western-led embargo and ultimately contributed to the coup that removed him from power.

Oil nationalization triggered the CIA‑backed 1953 coup in Iran
