Following the Persian defeat at Salamis (480 BC) and with Xerxes having been escorted to the Hellespont by his general Artabazus, the Persian army spent the winter of the same year in Thessaly and Macedonia. The Persian authority in the Balkans must have significantly decreased at the time, which encouraged the inhabitants of the Pallene peninsula to break away. Suspecting that a revolt against the Great King was meditated, in order to control the situation, Artabazus captured Olynthus, which was thought to be disloyal, and killed its inhabitants. The town had priorly been given to Kritovoulos from Toroni and to a fresh population consisting of Greeks from the neighboring region of Chalcidice, who had been exiled by the Macedonians (Herod. viii. 127). Though Herodotus reports that Artabazus slaughtered them, Boetiaeans continued to live in the area.
