The significance of the Iranian Revolution in 1979 lies in its dramatic shift from a pro-Western monarchy to an Islamic Republic led by Ayatollah Khomeini. This revolution was rooted in widespread dissatisfaction with the Shah’s regime, characterized by authoritarianism, economic disparity, and cultural Westernization. The revolution galvanized diverse societal groups who sought political, social, and economic reforms. Its outcome reshaped regional politics, leading to reduced Western influence in Iran and heightened tensions between the U.S. and Iran. The establishment of a theocratic state also inspired Islamist movements across the Middle East, fundamentally altering the geopolitical landscape and international relations for decades to come.
