Achaeus (3) (d. 213 BCE), viceroy for *Antiochus (3) III of Seleucid Asia Minor and his kinsman (maternal uncle), probably the grandson of the Seleucid official Achaeus the Elder. In 223/2 he recovered Seleucid possessions in Anatolia from *Pergamum; exploiting Antiochus' involvement in the east (Molon's revolt and war against *Ptolemy (1) IV), he proclaimed himself king (220). His soldiers refused to fight Antiochus, but he maintained power until the king was free to quell his rebellion. After a two-year siege in Sardis, he was captured and duly executed as a traitor.Less
