Introduction. The article examines the causes and course of the Islamic Revolution in Iran in 1979. On February 1, 1979, the disgraced Ayatollah Khomeini returned to the country and took power into his own hands. The 1979 revolution was a series of events that led to the overthrow of the Pehi dynasty under Shah Mohammad Reza Pahlavi. It was actively supported by various Islamist and leftist organizations and student movements. The study of various aspects of the development of Iran at that time helps to objectively assess the uniqueness and relevance of its experience in terms of searching for optimal development options for each country, as well as relationships with the world community. Materials and Methods. The study was based on Iranian media materials. An analysis of the publications of the leading Iranian media of that time was carried out. Covering the violent upheavals through the eyes of eyewitnesses will significantly expand our understanding of those events. Discussion and Conclusion. Iran is a multinational state with a pronounced Islamic Shiite tradition, in which the principles of ancient Persian culture are still partially embodied. The fall of the Shah’s regime and the rise to power of the clergy, who were not associated with the desire for progress, reflected the desire of the revolutionary forces to create in Iran a socio-economic model that would take into account national and religious characteristics. The created Islamic form of government in Iran (Islamic Republic of Iran) was intended to harmonize the cultural heritage, Islamic traditions and the need for modernization.
