Gaius Caesar
Ariobarzanes II served as a loyal Roman client king and was used as a key element in Augustus’ Asian policy. Ariobarzanes II ruled both Armenia and Media Atropatene. He accompanied Augustus’ grandson and adopted son Gaius Caesar to Armenia. When Gaius and Ariobarzanes II arrived in Armenia, the Armenians being fiery and proud, refused to acknowledge Ariobarzanes II as their new king, especially as he was a foreigner in their country. The Armenians revolted against Rome under the leadership of a local man named Addon.
