After the victory of the Islamic Revolution, a referendum was held by Interim Government of Iran on the 30th and 31 March 1979 (10 and 11 Farvardin 1358), asking people to vote either Yes or No to an Islamic Republic. The results of the referendum were announced soon after by Ayatollah Khomeini on April 2, 1979, with 98.2 percent of the Iranian citizens voting in favor of an Islamic Republic.
