Shapur II
The nobles of Armenia were infuriated by the brutality of Shapur II and his treatment of Arshak II with members of 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 signed a treaty, and Arshak II and members of his family were released from prison. As Arshak II's father was depressed and blinded from his experience in captivity, he abdicated his throne, and Arshak II succeeded his father as Armenian King in 350.
