Revolution and social change are some of extensive discussions in the social science. Since the victory of the Islamic Revolution was a special case and contrary to the sociological theories of revolution, thus it significantly affected this area. In the meanwhile, Imam Khomeini represented a viewpoint for analyzing the Islamic Revolution which had significant fundamental differences with modern theories. That's why Imam's theory has been less considered so far and it was only rebuilt on the sidelines of revolution sociological theories at best. This article seeks to review Imam Khomeini's thoughts using descriptive method and beyond works and reconstructions conducted before to discover the conceptual structure of Imam's standpoint. Unlike modern theories of sociology, what is more stressed along with emphasis on explanation of the social revolution and social factors of the revolution in Imam Khomeini's theory is the "revolution from inside". Although, the conceptual structure introduced by Imam Khomeini in the analysis of social revolution is focused on case study of Iran's Islamic Revolution, bit in a general way it has the capacity and ability to explain and Islamic and social revolution. In Imam's view, the Islamic Revolution is a product of a four-step process. In the first step, the plan of revolutionary Islam and its conflicts with rigid and modern interpretations of Islam was proposed. This cognitive contradiction led to the public awareness and formation of a human revolution. Human revolution is a central concept yet complex of this analysis which is performed by the unseen hands of God from the inside of humans while having social objective grounds. The product of this internal revolution is a new born and unpredictable baby called revolutionary human. The revolutionary human who is seeking social revolution would carry out distinct actions which in the end lead to the establishment of the Islamic Revolution.
