The Great Kings of Persia ruled over the largest Empire of antiquity, stretching from Libya to the Steppes of Asia, and from Ethiopia to Pakistan. At the heart of the Empire was the fabled palace-city of Persepolis where the Achaemenid monarchs held court in unparalleled grandeur. From here, Cyrus the Great, Darius, Xerxes, and their heirs passed laws, raised armies, and governed their multicultural Empire of enormous diversity. The Achaemenids, however, were one of the great dysfunctional families of history. Brothers fought brothers for power, wives and concubines plotted to promote their sons to the throne, and eunuchs and courtiers vied for influence and prestige. Our understanding of the Persian Empire has traditionally come from the histories of Greek writers such as Herodotus – and as such, over many centuries, our perspective has been skewed by ancient political and cultural agendas.
