The Iranian Revolution of 1979 marked a seismic shift in Middle Eastern politics. It transformed Iran from a Western-aligned monarchy to an Islamic theocracy, challenging regional power dynamics and inspiring Islamic movements across the Muslim world. The revolution's impact extended far beyond Iran's borders. It strained relations with the US and Arab neighbors, fueled sectarian tensions, and sparked the Iran-Iraq War. These events reshaped the geopolitical landscape of the Middle East for decades to come.
