Antiochus XI Epiphanes or
Philadelphus, ruler of the
Greek Seleucid kingdom, was a son of
Antiochus VIII Grypus and his wife
Tryphaena. Antiochus XI was a brother of
Seleucus VI Epiphanes and a minor participant in the civil wars which clouded the last years of the once glorious Seleucids, now reduced to local dynasties in
Syria. Following the defeat of his brother in 95 BC by
Antiochus X Eusebes, Antiochus XI and yet another brother,
Philip I Philadelphus, opted for revenge and besieged
Antiochia. After the campaign had ended in defeat, Antiochus was forced to flee but drowned in the river Orontes while trying to cross it on horseback. The year was 92 BC.
