- Iranian Empire: The Iranian Empire, also known as the Persian Empire, had a decentralized political structure. It was governed by a king who held considerable power but was assisted by a council of nobles and advisors. The empire was divided into satrapies, each ruled by a satrap who governed with relative autonomy.

Religious Beliefs:

- Iranian Empire: The Iranians followed the Zoroastrian religion, which was founded by the prophet Zoroaster. They believed in the existence of a supreme deity, Ahura Mazda, and considered him the creator of the universe. Zoroastrianism emphasized the eternal battle between good and evil, with humans having the choice to align with either side.

Cultural Practices:
