Arsacid dynasty of Iberia

The Iberian Arsacid or Arshakiani (Georgian: არშაკიანი) is the name of the dynasty of Georgian kings of Kartli (Iberia) of Parthian Arsacid and Pharnavazid origin that ruled Iberia from c. 189 until 284 AD. They were succeeded by the Chosroid dynasty.

Once the Arsacids, in the person of Vologases II (r. 180-191), had consolidated their hold on the Armenian throne by 180, they gained momentum to interfere in Iberia. According to the medieval Georgian chronicles, the king of Armenia, whom Professor Cyril Toumanoff identifies with Vologases II, helped the rebellious nobles of Iberia overthrow his wife’s brother Amazaspus II of Iberia, last of the Pharnabazids, and replace Amazaspus with his son Rev I, whose reign (189-216) inaugurated the Arsacid dynasty in Iberia.

Even as the Arsacids set on the thrones of three Caucasian kingdoms – those of Armenia, Iberia, and Albania – the dynasty was dislodged, in 226, from power in its original homeland and the more powerful and dynamic Sassanid dynasty emerged as new masters of the Iranian Empire. Although the later Georgian chronicles documents this change of power, its account of that period is full of anachronisms and semi-legendary allusions, providing little or no details about the effect of Iranian resurgence on Arsacid Iberia. What we know of that period comes from Classical sources as well as Sassanid inscriptions.
