What political system did the Persian empire have?

The Persian Empire, particularly during the Achaemenid period, operated under a centralized autocratic system led by a king known as the Shahanshah, or "King of Kings." The empire was divided into several provinces called satrapies, each governed by a satrap who acted as the king's representative, collecting taxes and maintaining order. This administrative structure allowed for efficient governance over a vast and diverse territory, while the use of local customs and languages helped to integrate various cultures within the empire. The Persian Empire is often noted for its relatively progressive policies regarding local governance and religious tolerance.
