Why was Reza Pahlavi overthrown?

Reza Pahlavi was overthrown during the Iranian Revolution of 1979 due to widespread discontent with his authoritarian regime, which was characterized by political repression, corruption, and human rights abuses. Economic difficulties, social inequality, and Westernization policies alienated many Iranians, including religious leaders and various political factions. The revolution was fueled by a broad coalition of opposition groups that sought to replace his rule with a more democratic or Islamic government. Ultimately, the revolution led to the establishment of the Islamic Republic under Ayatollah Khomeini.
