The Iranian Revolution (1978-1979) was the social movement that arose from widespread and diverse discontent with the monarchic government of Iran. The revolution was fought against the regime of Mohammad Reza Shah (r. 1941-1979), and it culminated in the end of the Pahlavi dynasty and the establishment of the Islamic Republic of Iran (1979 to present).
