History begins in the Early Iron Age (1100–900 BCE). Thucydides mentions that, on the way home from Troy, a contingent from Pellene in Achaea of the Peloponnesus, driven to Chalcidice by a storm, deciding to stay, founded Skione, according to the Skionians, he says. The date is debatable, but if Troy fell in 1180 BCE, it would have been in the 12th century BCE. This is the first report of Hellenes in Chalcidice. The settlements of the period are on fortified heights (acropoli), whether on the coast or in the interior. The culture shows affinities to that of southern Greece. According to other sources, Chalcidice was also occupied by tribes of Thrace and other people of unknown language driven from Macedon by the Macedonians moving in.
