For years the chieftains and their war bands ravaged the western half of Asia Minor, as allies of one or other of the warring princes, without any serious check, until they sided with the renegade Seleucid prince Antiochus Hierax, who reigned in Asia Minor.
However, Antiochus Hierax, a younger brother of Seleucus, was set up as a rival in Asia Minor against Seleucus by a party to which Laodice herself adhered.
