Ariobarzanes (in
Greek Ἀριoβαρζάνης; ruled 363–337 BC) succeeded his kinsman or father,
Mithridates or alternatively succeeded another
Ariobarzanes I of Cius, as ruler of the Greek city of
Cius in
Mysia, governing for 26 years between 363 BC and 337 BC for the
Persians. It is believed that it was he and his family which in mid-360s BC revolted from the rule of the Persian king
Artaxerxes II, but ended up in defeat by 362 BC. He was succeeded as governor of Cius by
Mithridates, possibly his son or possibly a kinsman such as a younger brother.
