Ariobarzanes of Phrygia

Ariobarzanes conducted the Athenian ambassadors, in 405 BCE, to his sea-town of Cius in Mysia, after they had been detained three years by order of Cyrus the Younger.

[3] He appears to have still held some high office in the Persian court in 368 BCE, as we find him, apparently on behalf of the king, sending an embassy led by Philiscus of Abydos to Greece in that year.

[4] Both Philiscus and Ariobarzanes, as well as three of his sons, were made citizens of Athens, a remarkable honor suggesting important services rendered to the city-state.

Several other satraps sided with Ariobarzanes, including Mausolus of Caria (briefly), Orontes I of Armenia, Autophradates of Lydia and Datames of Cappadocia.

The rebel satraps also received support from the pharaoh of Egypt, Teos, as well as from some of the Greek city states, with the Spartan king Agesilaus II coming to their assistance with a mercenary force.

Ariobarzanes withstood a siege at Adramyttium in 366 BC, from Mausolus of Caria and Autophradates of Lydia, until Agesilaus negotiated the besiegers' retreat.

Ariobarzanes was Satrap of Hellespontine Phrygia .
