Proclaiming himself "King of Kings of Iran," he established a new imperial dynasty rooted in Zoroastrian tradition and centralized governance. His reign marked the end of Arsacid (Parthian) rule and laid the foundation for a revitalized Persian empire that would endure for over four centuries and emerge as a major rival to Rome. Early coinage like this tetradrachm reflects a transitional artistic style, blending Parthian elements with the emerging Sasanian identity.
