Demetrius I (Ancient Greek: Δημήτριος Α`, 185 – June 150 BC), surnamed Soter (Ancient Greek: Σωτήρ), reigned as king (basileus) of the Hellenistic Seleucid Empire from November 162 to June 150 BC. Demetrius grew up in Rome as a hostage, but returned to Greek Syria and overthrew his young cousin Antiochus V Eupator and regent Lysias. Demetrius took control during a turbulent time of the Empire, and spent much of his time fighting off revolts and challenges to his power from threats such as Timarchus and Alexander Balas.
