Doris was one of the oldest members of the Delphic Amphictyony and, according to Thucydides, it was an important and strategic region already 25 years before the Peloponnesian War, the first time when the Phoceaens and the Lacaedemonians first  clashed against each other, the former as invaders and the latter as protectors of the Doric capital Kytinion.
