The Iranian Revolution's "Days of Dawn"

Each year, February 2 to 11 marks the "Days of Dawn" for the Islamic Revolution in Iran. Although the revolution started with the educated middle class protesting the shah's economic policies, theology students and the Shia ulama pretty quickly took control of the movement to oust the shah. As a result, when Shah Mohammed Reza Pahlavi abdicated, the Islamic Republic of Iran became the world's only theocracy.
