Vologases III of Parthia

High Quality Content by WIKIPEDIA articles! Vologases III of Parthia claimed the throne of the Parthian Empire about 105, in the last days of Pacorus II of Parthia (80-105). He reigned over the eastern portion of the kingdom from 105 to 147. The period was one of civil war in the Parthian kingdom; for the early part of his reign Vologases III contended with Pacorus II's legitimate successors Osroes I (105-116 and 117-129), Parthamaspates (116-117), and Mithridates IV (129-140), who ruled Mesopotamia. Preoccupied by conflicts with the Romans, particularly the invasion by Roman Emperor Trajan (98-117), they were unable to effectively challenge Vologases III.
