The Iranian Government is an Islamic Republic, established after the 1979 Iranian Revolution, which replaced the monarchy with a theocratic system. It is characterized by a unique blend of religious and political authority, where the Supreme Leader holds significant power over all branches of government, including the Executive, Legislative, and Judiciary. The government operates under a constitution that outlines the roles of various institutions. The President is elected by the public and manages the day-to-day affairs, while the Islamic Consultative Assembly (Parliament) is responsible for legislation. However, many candidates for these positions must be approved by the Guardian Council, which ensures alignment with Islamic principles.
