Vologases V of Parthia

Vologases V (Parthian: 𐭅𐭋𐭂𐭔 Walagash) was King of Kings of the Parthian Empire from 191 to 208. As king of Armenia (r. 180–191), he is known as Vologases II. Not much is known about his period of kingship of Armenia, except that he put his son Rev I (r. 189–216) on the Iberian throne in 189. Vologases succeeded his father Vologases IV as king of the Parthian Empire in 191; it is uncertain if the transition of power was peaceful or if Vologases took the throne in a civil war. When Vologases acceded the Parthian throne, he passed the Armenian throne to his son Khosrov I (r. 191–217).

Vologases' reign was marked by war with the Roman Empire, lasting from 195 to 202, resulting in the brief capture of the Parthian capital of Ctesiphon, and reaffirmation of Roman rule in Armenia and northern Mesopotamia. At the same time, internal conflict took place in the Parthian realm, with the local Persian prince Pabag seizing Istakhr, the capital of the southern Iranian region of Persis.
