Vologases II - King of Parthia

Vologases was most likely the weaker co-ruler with Oroses for many years, perhaps administering the eastern affairs of Parthia while Oroses suffered humiliating defeats at the hands of Trajan. When Vologases finally came to the throne himself, he appointed Mithridates IV to take over his duties in the east. He was succeeded by Vologases III.
