The ancient Greek tribes (Ancient Greek: Ἑλλήνων ἔθνη) were groups of Greek-speaking populations living in Greece, Cyprus, and the various Greek colonies. They were primarily divided by geographic, dialectal, political, and cultural criteria, as well as distinct traditions in mythology and religion. Some groups were of mixed origin, forming a syncretic culture through absorption and assimilation of previous and neighboring populations into the Greek language and customs. Greek word for tribe was Phylē (sing.) and Phylai (pl.), the tribe was further subdivided in Demes (sing. Demos, pl. Demoi) roughly matching to a clan.
