Demetrius III Eucaerus (150–87 BCE)
Born 150 BCE, died 87 BCE.
Demetrius III Theos Philopator Soter Philometor Euergetes Callinicus (Ancient Greek: Δημήτριος θεός Φιλοπάτωρ σωτήρ Φιλομήτωρ Εὐεργέτης Καλλίνικος, surnamed Eucaerus; between 124 and 109 BC – after 87 BC) was a Seleucid monarch who reigned as the King of Syria between 96 and 87 BC. The son of Antiochus VIII, he took control of Damascus after his father's murder while his brother Seleucus VI prepared for war against their father's half-brother and rival, Antiochus IX, who occupied the Syrian capital Antioch. The civil war dragged on; Seleucus VI eliminated his uncle, whose heir Antiochus X counterattacked and drove Seleucus VI to his death. Then the twins Antiochus XI and Philip I, brothers of Demetrius III, attempted to avenge Seleucus VI; it ended with the death of Antiochus XI and the interference of Demetrius III on the side of Philip I in a war against Antiochus X that probably lasted until 88 BC. In 89 BC, Demetrius III invaded Judaea and crushed the forces of its king, Alexander Jannaeus; his near victory was cut short by the death of Antiochus X.
