Seleucus VI Epiphanes was the oldest son of
Antiochus VIII Grypus and defeated his half-uncle
Antiochus IX Cyzicenus in
96 BC as revenge for his father's death, but the score was evened only the next year by Antiochus' son
Antiochus X Eusebes, and Seleucus had to flee from
Syria to
Mopsuesta[?] in
Cilicia, where he set up a court but was soon killed by the inhabitants, who could by no means afford his extravagant lifestyle. Four of his brothers, including
Antiochus XI Ephiphanes Philadelphus,
Philip I Philadelphus, and
Demetrius III Euergetes[?], continued the devastating civil war against the other branch of the family and each other.
