Cyrus the Great ruled at a rare moment when empires could have chosen domination or cooperation. In this lecture, Dr. Roy traces the rise of the Persian Empire under Cyrus, exploring how conquest, restraint, and an unprecedented vision of tolerance reshaped the ancient world. Dr. Roy examines how Cyrus combined military brilliance with ethical governance, creating the first known model of an empire built on pluralism, legal limits, and respect for human dignity.
