Immediately he had the threats of the Galatians, the same opponent Eumenes II of Pergamon was suffering of. When military attacks failed, the Galatians endeavored to discredit the Cappadocian king by incriminating him before the Roman senate (Polybios 31.8.2). Ariarathes V was just on the throne and still shaky, but he had more worries than the Roman senate, pretenders lay on the wait and soon would want to challenge for legitimacy. The Seleukid king Demetrios I Soter proposed to Ariarathes V to marry to his sister Loadice V, but he refused. Demetrios I outraged, supports Ariarathes V his brother, Orophernes II against the new king and a civil war starts in 158 BC. The Roman senate ordered the two dynasts to split the kingdom and reign jointly, but this did not succeed and Attalos II of Pergamon restored Ariarathes V as sole ruler. Afterwards Ariarathes V his sister Stratonice IV is married to king Attalos II of Pergamon. In the summer of 152 BC, Ariarathes V takes 'revenge' on Demetrios I Soter and together with Attalos II supports the pretender Alexander I Balas to usurp the Seleukid kingdom from Demetrios I. Finally, in 133 BC, Aristonikos, also known as Eumenes III, revolts in Pergamon. Ariarathes V, being a good friend of both the Romans as Pergamon, decided to intervene but unfortunately died in the battle around 130 BC. Please share your coins of Ariarathes V, other Cappadocian kings, the kings of Pergamon and the Seleukid kings Demetrios I and Alexander I Balas!
