Demetrius III Eucaerus

Demetrius III Theos Philopator Soter Philometor Euergetes Callinicus was a Seleucid monarch who reigned as the King of Syria between 96 and 87 BC. He was a son of Antiochus VIII and, most likely, his Egyptian wife Tryphaena. Demetrius III's early life was spent in a period of civil war between his father and his uncle Antiochus IX, which ended with the assassination of Antiochus VIII in 96 BC. After the death of their father, Demetrius III took control of Damascus while his brother Seleucus VI prepared for war against Antiochus IX, who occupied the Syrian capital Antioch.
