Successors of Kanishka I
Kanishka’s rule lasted for twenty-three years. His immediate successor was Vasishka, who had a short reign and was succeeded by Huvishka. The empire of Huvishka was not less extensive than that of theHuvishka gold coin traditional patron of Asvaghosha. It may have spread farther to the west, as a record of his reign has been unearthed at Wardak to the west of Kabul.
