Pacorus II
Pacorus II was King of Kings of the Parthian Empire from 78 to approximately 110 CE, a ruler of the Arsacid dynasty whose accession followed the death of his brother Vologases I amid challenges from rival aspirants to the throne.[1] His early control of Media Atropatene, granted by Vologases I, positioned him to assume central authority, as evidenced by coin issues commencing in April 78 at Seleucia-Ctesiphon.[1] Pacorus II's reign featured persistent internal instability, including insurrections by Artabanus III around 80–90 CE and Vologases II/III by circa 105 CE, yet he sustained imperial cohesion through military consolidation and diplomatic maneuvers, such as selling Osroene to Abgarus VII in 110 CE and corresponding with Dacian king Decebalus.[2] Numismatic records, spanning from depictions of a beardless youth to a bearded adult wearing diadems or tiaras, underscore the duration and legitimacy of his rule despite coinage gaps indicating periods of disruption.[1] A defining act was the deposition of Armenian king Tiridates I and installation of his son Axidares as successor circa 110 CE, asserting Parthian influence over this strategic buffer against Rome, though this precipitated tensions culminating in clashes with Emperor Trajan.[3][4] Pacorus II fathered multiple sons, including Axidares and Parthamasiris, who later vied for Armenian kingship, and his death around 105–110 CE paved the way for further dynastic fragmentation under Osroes I.[2][1]
