Marathesium

Marathesium or Marathesion (Ancient Greek: Μαραθήσιον) was a polis of ancient Ionia on the coast south of Ephesus, which was a member of the Ionian League. Marathesium was too small to be a member of the League or even to stand independently on its own. It has been classified recently as a dependent polis of one of the members of the League, first of Melia, then of Miletus after Melia had been defeated in the Meliac War, then of Samos, by lawsuit based on its occupation, and finally of Ephesus by a treaty involving the swap of cities.
