 The Middle Persian geography text "Šahrestānīhā ī Ērānšahr" ("The Provincial Capitals of Iran") reports that Yazdegerd had Jews settled in Spahan at Shushandukht's request, and she was the mother of his son Bahram V. According to the Iranologist Ernst Herzfeld, the Tomb of Esther and Mordechai in Hamadan was not the burial site of Esther and Mordechai but that of Shushandukht.Roman sources describe Yazdegerd I as an astute, benevolent and friendly ruler.Said to be well-read, "from the start" he was known for "nobility of character" and as a champion of "the poor and the wretched."
