Iran has a unique system of government known as a "theocratic republic," where religious leaders hold significant power alongside elected officials. The Supreme Leader, a religious figure, has authority over all branches of government, including the military and judiciary. This system merges theocracy with republican elements, as citizens do participate in elections for the Parliament and the President. However, candidates must be approved by the Guardian Council, which is composed of members appointed by the Supreme Leader. This structure allows for religious doctrine to influence laws and governance while maintaining a semblance of democratic process.
