March 1979 Iranian Islamic Republic referendum in the context of "December 1979 Iranian constitutional referendum"

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.
