The Islamic Republic of Iran was proclaimed on 1 April 1979 after the results of a referendum in which allegedly more than 98% voted for this system. The Provisional Government took office on 12 February, right after the former government fell, but it quickly became apparent that this government lacked any real power, which was instead concentrated in the Islamic Revolutionary Council (which was dominated by hard-line religious fundamentalists) and the local Islamic Komitehs (committees). The PG was composed mainly of elements from the FMI (including Bazargan, Taleghani, Sahabi, Yazdi, Nazih), but also included a few leaders of the National Front (Sanjabi, Ardalan, Forouhar). This period expressed the height of the LMI's influence over Iranian politics, but it was not to last. By Aug. 1979, the new government was clamping down on dissent, outlawing nearly all political parties and instituting a campaign of terror against its critics. The Bazargan cabinet resigned en masse on 5 November 1979, and thus, ended the Interim Government of Iran.
