Vologases VI was a prominent monarch of the Parthian Empire, reigning from two hundred eight to two hundred thirteen. His rule was marked by a significant dynastic struggle with his brother, Artabanus IV, which ultimately led to a division of power within the empire.
By two hundred sixteen, Artabanus IV had gained control over most of the Parthian territories and was even recognized as the supreme ruler by the Roman Empire. Despite this setback, Vologases VI maintained his authority in Seleucia until approximately two hundred twenty-one or two hundred twenty-two.
During his reign, Vologases VI's influence extended into Mesopotamia, where coin mints bearing his name continued to circulate until two hundred twenty-eight. This period marked the end of his reign, as he was presumably defeated by the rising Sasanian Empire, which had previously triumphed over Artabanus IV and succeeded the Parthians as the dominant power in Iran.
