Question: Who is the paternal grandfather of Shahriyar (Son Of Khosrow Ii)?
Sentence (from "Khosrow II"): He lost his throne, then recovered it with Roman help, and, a decade later, went on to emulate the feats of the Achaemenids, conquering the rich Roman provinces of the Middle East; much of his reign was spent in wars with the Byzantine Empire and struggling against usurpers such as Bahram Chobin and Vistahm.
