Δωριῆς, Δωριεῖς; Latin: Dores, Dorienses) is a small mountainous district in ancient Greece, bounded by Aetolia, southern Thessaly, the Ozolian Locris, and Phocis.

It lies between Mounts Oeta and Parnassus, and consists of the valley of the river Pindus (Πίνδος), a tributary of the Cephissus, into which it flows not far from the sources of the latter.

The Dorians would appear at one time to have extended across Mount Oeta to the sea coast, both from the preceding account and from the statement of Scylax, who speaks (p. 24) of Λιμοδωριεῖς.

In the Bibliotheca[12] Dorus is represented as occupying the country across the Peloponnese, on the opposite side of the Corinthian gulf, and calling the inhabitants after himself Dorians.

By this description is evidently meant the whole country along the northern shore of the Corinthian gulf, comprising Aetolia, Phocis, and the land of the Ozolian Locrians.

Starting at the isthmus of Corinth, there were first Megara, the territory of which extended north of the isthmus from the Saronic to the Corinthian gulf; next came Corinth, and to its west Sicyon; south of these two cities were Phlius and Cleonae: the Argolic peninsula was divided between Argos, Epidaurus, Troezen, and Hermione, the last of which, however, was inhabited by Dryopes, and not by Dorians.

[13] The silence of Homer indicates that the Dorian conquest of Peloponnesus must have taken place subsequent to the time of the poet, and consequently must be assigned to a much later date than the one usually attributed to it.

Doric colonies were founded in mythical times in the islands of Crete, Melos, Thera, Rhodes, Cos, and ancient Doris (located on the southwest coast of modern Turkey).

The members of this hexapolis were accustomed to celebrate a festival, with games, on the Triopian promontory near Cnidus, in honour of the Triopian Apollo; the prizes in those games were brazen tripods, which the victors had to dedicate in the temple of Apollo; and Halicarnassus was struck out of the league, because one of her citizens carried the tripod to his own house instead of leaving it in the temple.

Corinth, the chief commercial city of the Dorians, colonised Corcyra, and planted several colonies on the western coast of Greece, of which Ambracia, Anactorium, Leucas, and Apollonia were the most important.

[15] 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.

[17] Their towns suffered much in the Phocian, Aetolian, and Macedonian wars, so that it was a wonder to Strabo that any trace of them was left in the Roman times.
