The phrase 'I heard the voice of your revolution' enters history

The campus became a focal point for opposition to military rule and royal government.

Deaths and injuries intensified anger among students, families and the wider public.

Banks, government-linked businesses and other targets were attacked amid the breakdown of reconciliation.

The violence and unrest made the prime minister's policy of conciliation politically untenable.

He acknowledged the revolutionary movement and promised to correct abuses and past mistakes.

The speech offered change without accepting the central opposition demand that the Shah leave power.

The Shah replaced the reconciliation government with a military-led cabinet.

Authorities attempted to restore order through arrests, censorship, curfews and troop deployments.

His resignation marked the failure of limited concessions to divide or demobilize the opposition.
