The Islamic Revolution, led by the late Imam Khomeini, culminated in the overthrow of Mohammad Reza Pahlavi and put an end to 2,500 years of monarchical rulein Iran.
In a landmark two-day referendum held on March 30-31, 1979, more than 98.2 percent of eligible Iranians voted “yes” to the establishment of an Islamic Republic in the country.
The vote, which was held less than two months after the victory of the Islamic Revolution, is considered a turning point in the modern history of Iran.
Since then, the nation annually celebrates Farvardin 12 (April 1) on the Iranian calendar as the Islamic Republic Day.
