Iran becomes Islamic Republic

1 April 1979, Tehran, Iran

Following the successful overthrow of the Us-backed monarch, a referendum approved (by 99%) the formation of an Islamic Republic and Iran was set on an entirely new path under its leader Ayatollah Ruhollah Khomeini. His success was an inspiration to Muslims around the world and sent ripples throughout the Middle East, helping to reshape the political landscape of the region and setting up much of the political divide that exists to this day.
