The bringing down of one of the most oppressive regimes, that of the Shah monarchy, was a remarkable event of twentieth century. Whether one finds the outcome of the Revolution in terms of the establishment of an Islamic Republic under the dominance of Ulama (Islamic clerics, in narrow, contemporary sense) agreeable or disappointing, a most remarkable aspect of this revolution that has become an object of interest of observers of contemporary events is the mass movement that underlies the revolution. Indeed, the kind of mass participation - in terms of both absolute and relative magnitude - in the movement leading to the revolution is still unprecedented.While the role of the Ulama, especially that of Imam Khomeini, received overwhelming attention worldwide, there were other powerful influences that shaped the ethos of the revolution. One such source of influence was Dr. Ali Shariati. A sociologist, trained at Sorbonne University (France), he was gunned down in United Kingdom by Savak for his anti-monarchy stance and popular influence among the modern educated and youth of pre-revolutionary Iran.
