A series of events fueled the protests against the shah’s regime. The burning of Cinema Rex and the Black Friday riots mobilized large swaths of the Iranian public against the king. Religious groups operated through their networks to protest the Pahlavi state. The shah’s government went through a rapid succession of prime ministers, as Ayatollah Khomeini became anointed as the leader of the opposition, which included many different political groups. The revolution came crashing in. Within months, Islamic policies reversed decades of Pahlavi secular reforms as women were forced to reveil. The regime promptly executed Pahlavi diehards and political activists who embraced different ideologies. An Islamic Republic took shape and punished America for its ties to the shah by taking US diplomats as hostages. Meanwhile, Iraq seized on this moment of domestic turmoil to launch a devastating war against Iran. That island of stability became a harbor of volatility.
