Seleucus now held the whole of Alexander's conquests except Egypt and moved to take possession of Macedonia and Thrace. He intended to leave Asia to Antiochus and content himself for the remainder of his days with the Macedonian kingdom in its old limits. He had, however, hardly crossed into the Thracian Chersonese when he was assassinated by Ptolemy Keraunos near Lysimachia in September (281 BC).
