What is "athamanians"

Athamanians or Athamanes were an ancient Greek tribe that inhabited south-eastern Epirus and west Thessaly. Although regarded as " barbarians" by Strabo and Hecataeus of Miletus, the Athamanians self-identified as Greeks. The existence of myths about Athamas and Ino in Achaean Phthiotis suggests that the Athamanians were settled there before 1600 BC. They were an independent semi-barbarian tribe (in 395 and 355 BC according to Diodorus Siculus) and were occasionally allies of the Aetolians. Amynander and Theodorus of Athamania are reported kings of the Athamanians.
