In what year did the Shah of Iran fall from power?

The Shah of Iran fell from power in 1979, marking a significant turning point in Iranian history. This event was part of the Iranian Revolution, which led to the establishment of an Islamic Republic under the leadership of Ayatollah Khomeini. The revolution was driven by a variety of factors, including widespread discontent with the Shah's authoritarian rule, economic issues, and a desire for cultural and religious revival among many Iranians. Protests and civil unrest escalated throughout 1978, ultimately culminating in the Shah's departure from the country in January 1979. Following his exile, Khomeini returned to Iran and assumed leadership, fundamentally altering the political landscape of the country and impacting global politics in the years that followed.

The other years provided do not coincide with the Shah's fall; 1975 was before the revolution gained momentum, while both 1981 and 1985 came after the establishment of the Islamic Republic.
