Chalkon - Alexander I Balas

Alexander I Balas seized the Seleucid throne by claiming to be a son of Antiochus IV Epiphanes — a claim almost certainly fabricated, reportedly manufactured with the backing of Attalus II of Pergamon and the Roman Senate, who found him a useful instrument against Demetrius I. He held the throne from 150 BC only through a shifting web of foreign sponsors, including the Ptolemaic court, which gave him the hand of Cleopatra Thea. His reign collapsed when Demetrius II and Ptolemy VI turned against him simultaneously in 145 BC; he fled and was killed shortly after, his severed head reportedly sent to Ptolemy VI.
