Edonis or Edonida (Ancient Greek: Ἠδωνίς, Ἠδωνίδα), also transliterated as Edonia, was an ancient region of Thrace which later became a district of Macedon. Its name is derived from the ancient Thracian inhabitants of the region, the Edonians.[1] Later, the Greeks settled in the region, drove out the Edonians and built several colonies, including Amphipolis and Eion.[2] It was bordered by Odomantice in the north, Bisaltia in the west, and the Aegean Sea in the south, and was separated from Thrace proper by the river Nestos in the east.
