Pamahalaang theocracy, or theocracy, is a form of government where religious leaders or institutions hold political power, and the state is governed by divine guidance as interpreted by these leaders. In a theocracy, laws and policies are often based on religious doctrines, and political authority is derived from a belief in a higher power. This system contrasts with secular governments, where religion and state are separated. Examples of theocratic governance can be found in some interpretations of Islamic law in countries like Iran.
