Overview
Antiochus V Eupator (Greek: Αντίοχος Ε' Ευπάτωρ), whose epithet means "of a good father" (c. 172 BC – 161 BC) was a ruler of the Greek Seleucid Empire who reigned from late 164 to 161 BC (based on dates from 1 Maccabees 6:16 and 7:1).
He was appointed as king by the Romans with his protector Lysias as regent.
Biography
Early life and succession
Antiochus V was only nine years old when he succeeded to the kingship, following the death in Persia of his father Antiochus IV Epiphanes and his mother Laodice IV. The general Lysias, who had been left in charge of Syria by Epiphanes, served as regent for the child, although he was challenged by other generals. The Roman Senate still kept Demetrius, son of Seleucus IV and the rightful heir to the throne, as hostage, refusing to release him because they considered it better to have Syria nominally ruled by a boy and his regent than the 22-year-old Demetrius.
