During the revolution, many political prisoners were freed and the Tudeh Party and other leftist groups were able to participate in the presidential and parliamentary elections for the first time in many years. However, the majority of seats in the Majlis were won by the Islamic Republican Party of Ayatollah Beheshti and leftist and nationalist organizations were forced out of the loop. The newly elected president, Abolhassan Banisadr, who had originally been close with Ayatollah Khomeini, also became increasingly frustrated with the developments that had been taking place and opposed the domination of the clergy and the religious factions in Iranian politics.
