Who did the Persian empire lay the foundations of government for?

The Persian Empire laid the foundations of government for several subsequent empires, most notably the Byzantine Empire and the Islamic Caliphates. Its administrative practices, such as efficient tax collection, a system of satrapies (provinces), and the use of a common language (Aramaic), influenced governance in these later states. Additionally, the empire's emphasis on bureaucracy and infrastructure set a precedent for future empires in managing vast territories.
