Why did the Islamic revolution happen?

The Islamic Revolution in Iran, which culminated in 1979, occurred due to a combination of factors, including widespread dissatisfaction with the Shah's authoritarian regime, social inequalities, and Western influence. Economic struggles, political repression, and a desire for greater religious and cultural autonomy fueled public discontent. Ayatollah Khomeini's leadership and the unification of various opposition groups, including secular and religious factions, played a crucial role in mobilizing the masses against the monarchy. Ultimately, the revolution was driven by a demand for political change and a return to Islamic values.
