アンティゴノス2世
Antiochus II succeeded his father in 261 BC, and thus began a new war for Syria. He reached an agreement with the current Antigonid king in Macedon, Antigonus II Gonatas, who was also interested in pushing Ptolemy II out of the Aegean. With Macedon's support, Antiochus II launched an attack on Ptolemaic outposts in Asia.
