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.
