died 160/159 BC
King of Pergamum (197 BC 0441; 160).
He continued the policy of his father, Attalus I Soter , of cooperation with Rome. He helped defeat Antiochus III , thus enlarging his realm. He brought his kingdom to its height and made it a great centre of Greek culture; in particular, he is credited with constructing nearly all the public buildings and sculpture on the Pergamum acropolis. He was suspected of disloyalty in the Roman struggle against Perseus ; Rome subsequently withdrew its support, and Eumenes's power and the glory of Pergamum declined. His brother Attalus II became coruler 0441; 160 BC.
