(Wikipedia) - The Council of the Islamic Revolution was a group formed by Ayatollah Khomeini on 12 January 1979, shortly before he returned to Iran. Over the next few months the council issued hundreds of rulings and laws, dealing with everything from nationalization to salaries. Its existence was kept a secret during the early days of the revolution, and its members and the exact nature of what the council did remained undisclosed until early 1980s. Some of council members like Morteza Motahhari, Ayatollah Taleghani, Bahonar, Beheshti, Gharani died during Iran–Iraq War or were assassinated by MKO during firsts years of the revolution. Some of remaining members were later alienated from the regime
The Council was composed of seven religious figures associated with Khomeini, seven secular opposition figures, and two representatives of the security forces. According to Akbar Hashemi Rafsanjani, Khomeini chose Beheshti, Motahhari, Rafsanjani, Bahonar, Mir Hossein Mousavi and Mousavi Ardabili as members. These invited others to serve: Bazargan, Taleghani, Khamenei, Banisadr, Mahdavi Kani, Yadollah Sahabi, Katirayi, Ahmad Sadr Haj Seyyed Javadi, Gharani and Ali Asghar Masoodi.
The council chose Mehdi Bazargan as the prime minister of the interim government of Iran.
It has been described as "a parallel government" that passed laws and competed with the official Provisional Revolutionary Government whose leading members had come from the council.
The council served as the undisputed government of Iran from the resignation of Bazargan and the rest of the Provisional Revolutionary Government until the formation of first parliament. (Nov, 6 1979 – Aug, 12 1980)
Among the actions the council took was the April 1979 creation of revolutionary tribunals to try and execute anti-revolutionaries; nationalization of companies; and the Cultural Revolution.
Members of the council were not in complete agreement as to how they wanted Iran to be governed. Abolhasan Banisadr, Ebrahim Yazdi, and Sadegh Ghotbzadeh, and Ayatollah Mahmoud Taleghani favored a democratic government, while Khomeini, Beheshti, and other clerics desired a constitution with a planning council but no elected parliament, as law would be based on Sharia law interpreted by clerics.
