Some later historians came to believe that this massive celebration contributed to events that ultimately culminated in the 1979 Iranian Revolution, although this claim has been described as dramatized with the extravagance being exaggerated by revolutionaries.[5] The event costs and luxury has been subject to many inflated historian and journalist accounts as a result. The revolution was led by Ruhollah Khomeini, an Ayatollah who garnered support from the Iranian people, various leftist and Islamist organizations,[6] and student movements to overthrow the Shah and establish the present-day Islamic Republic of Iran, for which he served as Supreme Leader from 1979 to 1989.
