Imperio sasánida
After hearing about the death of Peroz I during his war against the Hephthalites, Zarmihr left Iberia and returned to his son Sukhra in Ctesiphon, to protect the Sasanian Empire from the Hephthalites and to elect a new king. Balash, the brother of Peroz I, was crowned as the new king of the Sasanian Empire. However, it was in reality the son of Zarmihr, Sukhra who exercised real power over the Sasanian Empire. Zarmihr is thereafter no longer mentioned.
