The smell of burnt tires and tear gas hung over Jaleh Square on the morning of September 8, 1978. Thousands had gathered for a peaceful demonstration against the Shah’s regime, part of a wave of protests that had grown for months. The crowd was a mix: students, leftists, merchants from the bazaar, and a swelling number of religious followers mobilized by Ayatollah Khomeini from exile. They expected a confrontation, but not a slaughter.
Units of the Imperial Iranian Army, under martial law orders to clear any assembly, surrounded the square. Tanks blocked the exits. Witness accounts state that after an order to disperse, someone threw a stone. Then the machine guns on the tanks opened fire. Soldiers fired directly into the dense crowd. People fell where they stood, scrambling over bodies to reach the narrow alleyways. Official reports listed 88 dead, but opposition groups claimed the toll was in the hundreds. The square’s asphalt was slick with blood.
The event, branded ‘Black Friday’ by the opposition, severed the last strands of legitimacy for Mohammad Reza Pahlavi’s rule. It proved the Shah would use the army against his own citizens, alienating the middle class and unifying disparate factions under Khomeini’s leadership. The massacre transformed a political crisis into a revolutionary struggle. It was no longer about reform of the monarchy, but its eradication. Five months later, the Shah fled Iran.
