A constitutional referendum was held in Iran on 2 and 3 December 1979. The new Islamic constitution was approved by 99.5% of voters.
The referendum was held by the Council of the Islamic Revolution, because Bazargan's Interim Government—which oversaw the previous referendum—had resigned in protest to the U.S. Embassy hostage crisis.
Abolhassan Banisadr (Persian: ابوالØسن بنی‌صدر; 22 March 1933 – 9 October 2021) was an Iranian politician, writer, and political dissident. He was the first president of Iran after the 1979 Iranian Revolution abolished the monarchy, serving from February 1980 until his impeachment by parliament in June 1981. Before his presidency, he was the Minister of Foreign Affairs in the Interim Government of Iran.
Following his impeachment, Banisadr fled Iran and found political asylum in France, where he co-founded the National Council of Resistance of Iran. Banisadr later focused on political writings about his revolutionary activities and his critiques of the Iranian government. He became a critic of Supreme Leader Ali Khamenei and the country's handling of its 2009 elections.
