Editing Seleucus II Callinicus (section)

==The death of Antiochus Hierax==

Meanwhile, in Asia Minor, [[Pergamon]] now rose to greatness under [[Attalus I]]. Attalus' ambition to replace Antiochus Hierax as king of Asia Minor led to a major war and several battles during the 230s BC. In short order, Attalus defeated the Galatians, Antiochus Hierax and finally an attempt by Seleucus II to reclaim his control of Asia Minor. After being defeated by Attalus in four battles, Antiochus Hierax fled to Armenia, whose king gave him refuge. Antiochus Hierax then attempted to invade Mesopotamia. Andromachos, his mother's brother, commanded the Seleucid forces on this occasion and defeated him. Fleeing again, Antiochus finally perished in [[Thrace]], where he was killed by robbers in c. 226 BC.

Seleucus by this time had his hands full dealing with rebellion in Antioch instigated by his aunt, Queen [[Stratonice of Macedon|Stratonice]], who had previously been married to King [[Demetrius II Aetolicus|Demetrius II]] of Macedon. Upon returning to Syria after Demetrius II took another wife, Stratonice of Macedon proposed that she marry her nephew, or possibly demanded he avenge the insult to her honour by attacking Demetrius. In either case, Seleucus refused her suggestions and, infuriated, she raised Antioch in rebellion. Seleucus had to besiege the city, which he eventually recaptured. Stratonice fled to Seleucia, hoping to take refuge with Ptolemy III, but was captured en route and executed.

In the years after the defeat at Ancyra (237 BC), Seleucus focused on rebuilding his domains, expanding Antioch and suppressing rebellions in Babylon. By 227 BC, he had stabilised the situation enough to begin contemplating a new offensive against Attalus to retake Asia Minor.
