Ashura in Tehran
On Ashura — 11 December 1978 — an estimated two million people marched through Tehran to drumbeats, condemning Shah Mohammad Reza Pahlavi and, by name, US President Jimmy Carter.
The march was peaceful. Opposition marshals worked to keep discipline, and the contemporary UPI report describes no violence; the processions combined Shiʿite mourning practices, including breast-beating, with explicitly political marching against the monarchy.
Who organised it
Ashura offered a protected religious occasion around which clerics, bazaar organisations and the National Front could mobilise. National Front representatives had negotiated procession arrangements with government security officials, and marshals reportedly tried to remove young leftists shouting slogans more radical than the organisers wanted.
The secular-nationalist leader Karim Sanjabi was publicly acclaimed during the processions, while Ruhollah Khomeini's network treated Ashura as a climax of the struggle against the Shah.
What the crowds demanded
Resolutions associated with the two-day Tasuʿa and Ashura demonstrations demanded the Shah's abdication, Khomeini's return, political freedom and economic justice.
The numbers are estimates, not counts, and accounts disagree about which day produced the larger Tehran crowd: a contemporary figure of 1.5 million is given for 10 December, and a retrospective estimate of 6–9 million covers all of Iran across both days.
The demonstrations did not remove the Shah that day; he remained in Iran until 16 January 1979.

Date disputed. Sources disagree; the research places it at 1978-12-11.
What the sources leave uncertain
- The source list supplied only the year. The wording “two million demonstrate” most closely matches UPI’s December 11, 1978 report and headline.
- Crowd sizes were estimates, not turnstile counts. Contemporary and retrospective accounts disagree both about the totals and whether December 10 or December 11 produced the larger Tehran crowd.
- The nationwide estimate of 6–9 million covers both Tasuʿa and Ashura, December 10–11, and must not be presented as the count for Tehran on one day.
