The 1979 Revolution

The revolution was a developing confrontation across Iran rather than a single uprising in Tehran. In January 1978, an insulting newspaper article about Ruhollah Khomeini, a Shi‘i cleric living in exile, helped trigger demonstrations in Qom, an important religious center. Repression and mourning generated further mobilization, including demonstrations in Tabriz. Religious commemorations supplied occasions for renewed protest, connecting local grievances to a national confrontation with the monarchy. s1

The geography matters: Qom’s religious networks, Tabriz’s demonstrations, and Tehran’s increasingly direct confrontation with the state belonged to the same escalating crisis. Accounts disagree sharply about some casualty totals. Those disagreements should not obscure the documented role of state violence in sustaining opposition, but they make precise death counts unsuitable without further source comparison. s1s2

During 1978, demonstrations, changes of government, and repression failed to restore the shah’s authority. The shooting of demonstrators in Tehran’s Jaleh Square on 8 September became known as Black Friday. Later that year, Khomeini moved from Iraq to France, where greater access to international media strengthened his ability to address events in Iran. s2

The shah left Iran on 16 January 1979. His departure did not immediately settle who governed: Shapour Bakhtiar remained prime minister, while Khomeini rejected his administration’s legitimacy. Khomeini returned to Tehran on 1 February. Fighting and the withdrawal of military support from Bakhtiar brought the monarchy’s remaining governing structure down in February. These were successive steps in a breakdown of authority, rather than an orderly transfer between governments. s1s2

Mehdi Bazargan, associated with the Freedom Movement, headed a provisional government appointed by Khomeini. Their differences exposed a central unresolved question: would religious leadership guide a government, or exercise governing authority itself? Bazargan did not endorse Khomeini’s principle of velayat-e faqih, usually translated as guardianship of the Islamic jurist. His later account distinguished the overthrow of the shah from subsequent developments that he believed contradicted the revolution’s original aims. s1

The constitutional settlement established an Islamic Republic with elections and a powerful religious leadership. The constitution’s own account presents this outcome as the fulfillment of the revolution; that is the state’s foundational interpretation, rather than evidence that all opponents of the monarchy wanted the same political system. The text available here incorporates amendments made in 1989 and must not be read as an unchanged copy of the original settlement. s3

Understanding the revolution therefore requires separating two questions: how the monarchy lost power, and how one conception of revolutionary government became institutionally dominant. s1s3
