In which government does the authority over the people reside in religious leaders?

The type of government in which authority over the people resides in religious leaders is known as a theocracy. In a theocracy, religious law is used as the basis for governance, and leaders often hold both political and spiritual power. Examples include Iran, where the Supreme Leader has significant authority and is a religious figure, and the Vatican, governed by the Pope. In these systems, religious doctrine significantly influences political decisions and societal norms.
