Iberia breaks into revolt around 482 and declares its independence.

Peroz sends Adar-Vishnasp, the Persian Governor of Armenia, to Iberia to quell the rebellion, but no sooner has he left the province than had Armenia risen in rebellion and chosen an Armenian Christian as its king.

After restoring Persian rule in Iberia, Adar-Vishnasp rushes to Armenia to quell the rebellion but is soundly defeated.

Peroz responds by sending two large armies to the region, one under Adar-Narseh into Armenia and the other against Iberia.

Sahag, the Armenian king, is killed and Mihran is wreaking havoc in Persia, but just when success is within grasp, Peroz blunders by recalling Mihran and entrusting the command to one Hazaravough.

Hazaravough does not remain long in Armenia and is recalled in a few months.

This frequent rotation of military commanders ensure the loss of Armenia for the time being.
