Shah Overthrown: Iran's Islamic Revolution Victorious

The Iranian military declared itself neutral at 2 PM on February 11, 1979, and the 2,500-year-old Persian monarchy collapsed in a matter of hours. Ayatollah Ruhollah Khomeini’s Islamic revolutionaries seized government buildings, military installations, and television stations across Tehran. By nightfall, the most powerful American ally in the Middle East had become its most determined adversary. Shah Mohammad Reza Pahlavi had ruled Iran for 38 years, backed by American weapons, CIA training for his secret police (SAVAK), and billions in oil revenue. His White Revolution modernized the economy but alienated the clergy, the bazaar merchants, and the leftist intellectuals simultaneously. When protests erupted in 1978, the Shah’s security forces killed hundreds of demonstrators — which only fueled larger protests in a cycle that proved impossible to break. Khomeini, a 76-year-old cleric who had been exiled for fifteen years, returned to Tehran on February 1 to crowds estimated at five million. He appointed his own prime minister and demanded the Shah’s government resign. For ten days, two parallel governments existed. Guerrilla fighters and rebel military units attacked army bases on February 10, and when the Supreme Military Council declared neutrality the following afternoon, the old regime simply evaporated. The revolution replaced the Shah’s secular autocracy with a theocratic republic that fundamentally altered Middle Eastern politics. The Iran hostage crisis, the Iran-Iraq War, the rise of Hezbollah, and decades of confrontation with the West all flowed directly from this moment. A revolution that began with calls for democracy ended by creating a system of government that had never existed before in the modern world.
