In 641, during the reign of the Sasanian Empire, Yazdgerd III issued his last appeal to the nation from Rhages, before fleeing to Khorasan. Rhages was dominated by the Parthian House of Mihran, and Siyavakhsh—the son of Mehran, the son of Bahram Chobin—who resisted the 7th-century Muslim invasion of Iran. Because of this resistance, when the Arabs captured Rhages, they ordered the town destroyed and rebuilt anew by traitor aristocrat Farrukhzad.
