Synopsis: Demetrius II returns to Syria, but his unpopularity – and support for the Egyptian Queen Cleopatra II – results in a usurper named Alexander Zabinas taking most of his kingdom. Fleeing a military defeat, Demetrius is denied entry to Ptolemais-Akko by Cleopatra Thea, an act that leads to his death. The elevation of their son Seleucus V results in a darker tragedy.
“Released from confinement among the Parthians and restored to his throne, Antiochus’ brother Demetrius (II) decided to make war on Egypt…For his mother-in-law, Cleopatra (II), promised him the throne of Egypt as the reward for his assistance against her brother.” – Justin, Epitome of the Philippic History of Pompeius Trogus, Book 39.
“Demetrius (II), for his part, was defeated by Alexander (Zabinas) and, with misfortune besetting him on all sides, he was finally abandoned even by his wife and children. Left with a few slaves, he made for Tyre, intending to use the sanctity of the temple to protect himself; but as he disembarked from this ship he was killed on the orders of the governor.” – Justin, Epitome of the Philippic History of Pompeius Trogus, Book 39.
