Belonging to the Persian aristocratic families of Cappadocia, Ariobarzanes was also claimed as the direct descendant of Darius the Great’s companion, known as the king of Achaemenid Empire.
The minting of same Greek-style coins was continued by Ariobarzanes, as albeit, Ariarathids but with a new addition. The political allegiance with the Romans demonstrated his adoption of portraits similar to the Roman veristic style.
The citizens of Cappadocia put in place Ariobarzanes I, after the senate of Rome rejected Ariarathes IX of Cappadocia’s claim, and was further supported by Lucius Cornelius Sulla (Roman consultant).
He had on-and-off control of the kingdom, which was referred to as Roman protectorate. Moreover, he was removed by King Mithridates three times, before securing as well as increasing lands in the Third Mithridatic War, under general Pompey. Due to eventually being abdicated, he made the way of ruling under his son, Ariobarzanes II of Cappadocia in 63/62 BC.
The queen of Ariobarzanes was a Greek noblewoman, named: Athenais Philostorgos I. With Ariobarzanes, Athenais gave birth to two children, a son and a daughter. Son: Ariobarzanes II, who later succeeded his father; daughter: Isias, who was later married to the king Antiochus I Theos of Commagene.
