Peroz I
Peroz I, eager to avenge Varsken, sent his general Shapur Mihran to Iberia. Vakhtang then appealed to the Huns and the Armenian nobles, citing solidarity between Christians. After carefully weighing the decision, the Mamikonian prince Vahan Mamikonian agreed to revolt against the Sasanians. He defeated and killed Adhur Gushnasp, and thereafter declared Sahak II Bagratuni as the new "marzban". He also kept repelling several Sasanian counter-attacks.
