Ariobarzanes I of Cappadocia

Ariobarzanes I was appointed king of Cappadocia by the Roman Senate after the death of Ariarathes IX. He was a loyal ally of Rome, earning the title 'Philoromaios' (Friend of Rome), but faced repeated expulsions by Mithridates VI of Pontus.

Ariobarzanes I was expelled from Cappadocia by Mithridates VI of Pontus, who installed his own son as king. Ariobarzanes fled to Rome, seeking restoration through Roman military intervention.

Roman general Sulla restored Ariobarzanes I to the Cappadocian throne after expelling the Pontic puppet. This intervention was part of Rome's broader effort to counter Mithridates VI's expansion in Anatolia.

Ariobarzanes I was again expelled by Mithridates VI during the First Mithridatic War. He was restored by Roman forces under Lucius Licinius Murena after the war ended, but faced continued instability.

Ariobarzanes I abdicated the throne in favor of his son, Ariobarzanes II, after decades of rule marked by Roman dependency and repeated conflicts with Pontus. His reign ended with Cappadocia firmly under Roman influence.
