What it is
Islamic Republic Day is the most significant national holiday in Iran, marking the moment when the country officially became an Islamic Republic. It commemorates the announcement of the 1979 referendum results, in which an overwhelming majority voted to transform Iran’s political system. For Iranians, this day represents a turning point in their modern history, reflecting the collective will to shape the nation’s future. The holiday is a time for reflection on the ideals of the revolution and the values that have guided the country since.
Where it comes from
The origins of Islamic Republic Day lie in the aftermath of the 1979 Iranian Revolution, which ended the Pahlavi monarchy. Two months after the revolution’s victory, a referendum was held on 10 and 11 Farvardin to decide the country’s new political system. The choice presented to the people was clear: to establish an Islamic Republic, as advocated by Ruhollah Khomeini. On 12 Farvardin, the results were announced, with 98.2% voting in favor. This day has since been commemorated as the anniversary of the republic’s founding.
How it is celebrated
Islamic Republic Day is observed as a public holiday throughout Iran. Government offices, schools, and many businesses close for the day. The occasion is marked by official ceremonies, speeches, and gatherings that recall the events of 1979 and the referendum’s outcome. Media often broadcast documentaries and programs about the revolution and the establishment of the Islamic Republic. In some years, books and publications about the day and its significance are highlighted. The atmosphere is one of national reflection, with people considering the path their country has taken since the referendum.
