- Demetrius I Soter ("the Savior") was the eleventh king of the Seleucid Empire, ruling from 162 to 150 BC. He was sent to Rome
as a hostage for the good behavior of his uncle, Antiochus IV, but escaped back to Syria in 162 BC. After disposing of Antiochus
V and the regent Lysias, Demetrius I put down the usurpation of Timarchus in 160 BC and successfully fought against the Maccabean
Jewish rebels in southern Coele Syria. He further upset the balance of power in Asia Minor by dethroning Ariarathes V of Cappadocia.
His many enemies advanced the claims of Alexander I, a supposed son of Antiochus IV, as rightful Seleucid king in 152 BC.
After several years of conflict between the two for control of Syria, Demetrius was killed in battle in 150 BC.
