Agesilaus II
Ariobarzanes sought foreign aid and he received it from King Agesilaus II of Sparta. Ariobarzanes withstood a siege at Adramyttium in 366 BC, from Mausolus of Caria and Autophradates of Lydia, until Agesilaus negotiated the besiegers' retreat. As signal of sympathy in the effort, Athens made Ariobarzanes and three of his sons citizens of Athens. Ariobarzanes was betrayed by his son Mithridates to his overlord, the Persian king, who had Ariobarzanes crucified.
