Shapur II
The Armenian nobles infuriated by the brutality of Shapur II and his treatment of Tiran and his family, took up arms and fought against Shapur II and his army with assistance from the Romans. They successfully drove Shapur II and his army out from Armenia. After Shapur II was defeated, he had signed a treaty and agreed to release Tiran and his family from prison. As Tiran was depressed and blinded, he abdicated his throne and his second son Arsaces II (Arshak II), succeeded him father as Armenian King in 350.
