So they wouldn't rebel
Early in their history, the Persians often fought other peoples of Southwest Asia. In 550 BC the Persian king Cyrus II won independence from a group called the Medes. He went on to conquer almost all of Southwest Asia. His well-organized army included many war chariots and a powerful cavalry. Cyrus let the people he conquered keep their own customs. As a result, few people rebelled and the empire remained strong. By the time he died around 529 BC, Cyrus ruled the largest empire the world had ever seen. He became known in history as Cyrus the Great.
Cyrus the Great actively reached out to minorities and tribes in the areas he conquered and gave them a stake in the local government and the maintenance of their holy places. Since Cyrus' Empire did not seek to quash minority rights, but improve them, the conquered people aligned with the government forces, leading to general peace and security within the Persian Empire under his rule. Some modern governments might learn something from his example.
