North Macedonia geographically roughly corresponds to the ancient kingdom of Paeonia, which was located immediately north of the ancient kingdom of Macedonia. Paeonia was inhabited by the Paeonians, a Thracian people, whilst the northwest was inhabited by the Dardani and the southwest by tribes known historically as the Enchelae, Pelagones, and Lyncestae; the latter two are generally regarded as Molossian tribes of the northwestern Greek group, whilst the former two are considered Illyrian. The headwaters of the Axios river are mentioned by Homer as the home of the Paeonians allies of Troy.
