The Iranian Revolution of 1979 had a significant impact on the politics of many Arab countries because it showed that a government could be established based on Islamic principles. This inspired various political movements across the region that sought to integrate Islam into governance. Additionally, the success of the revolution highlighted the potential for popular uprisings against authoritarian regimes, influencing political thought and action in neighboring countries.
