Iran's Islamic Revolution 40 years on
The Shah ran out of time
Two months before Khomeini's return to Iran, an estimated six to nine million people took to the streets in the country's major cities. The demonstrations were largely peaceful, compared to the violent September 8, 1978, protests. The Shah regime, headed by Shah Mohammed Reza Pahlavi, had realized that its time in power was over and that they could not stop Khomeini's return.
