Persia Cyrus the Great, after his victory over the Medians, founded the Achaemenid Empire. The Achaemenid Empire would become one of the most formidable in the ancient Near East/Central Asia. One of the reasons why the Achaemenid grew in power, wealth, and stature was due to the unique combination of a strong centralized government and the satrapy system. Another reason why the Persian Empire grew and lasted as long as it did was that its rulers understood how to turn diversity into a strength.

Also part of the satrapy system included unified armies and courts. There were federal, or king-level, court systems as well as local ones.

Thus, the Persian emperors emphasized the multi-lingual, multi-ethnic, and multi-religious differences of their subjects by allowing his subjects a strong degree of freedom. The reason for the King's decision to serve as an egalitarian leader was to maintain peace and prevent uprisings that would certainly have resulted if a group of people were unhappy with their governance.
