10. Cyrus the Great
Cyrus the Great was one of the greatest leaders in the history of Iran, having unified the Persian Empire and turned it into a global force. In the process, he brought much of the Middle East together under Persian rule, leading to a flourishing of Persian culture. Cyrus the Great built his capital city at Pasargadae, which Alexander the Great eventually destroyed; the ruins still stand a short distance from his tomb. He was also an early champion of religious tolerance and allowed subjects of different nationalities and faiths within his empire to practice their beliefs freely.
