 The war with the Iranian Huns may have reawakened the mythical rivalry between the mythological Iranian Kayanian rulers and their Turanian enemies, which is illustrated by Younger Avestan texts.The title of Ramshahr (peacekeeper in [his] dominion) was added to the traditional "King of Kings of the Iranians and non-Iranians" on Yazdegerd's coins.In the Middle Persian heroic poem "Ayadgar-i Zariran" ("The Testament of Zarer"), the title was used by the last Kayanian monarch (Vishtaspa) and occurs in the 10th-century Zoroastrian "Denkard".
