History of the Peloponnesian War

Such were the preparations and such the feelings with which the Hellenes went into the conflict. And the states which each side had as its allies when it entered the war were as follows.

These were the allies of the Lacedaemonians: all the Peloponnesians south of the Isthmus with the exception of the Argives and Achaeans (these latter had friendly relations with both sides, and the Pellenians were the only Achaeans who at first took part in the war with the Lacedaemonians, though eventually all of them did), and outside of the Peloponnesus the Megarians, Boeotians, Locrians, Phocians, Ambraciots, Leucadians, and Anactorians.

Of these, the Corinthians, Megarians, Sicyonians, Pellenians, Eleans, Ambraciots, and Leucadians furnished ships, while cavalry was contributed by the Boeotians, Phocians, and Locrians, and infantry by the other states.

These were the allies of the Lacedaemonians. Those of the Athenians were: the Chians, Lesbians, Plataeans, the Messenians of Naupactus, most of the Acarnanians, the Corcyraeans, the Zacynthians, and in addition the cities which were tributary in the following countries: the seaboard of Caria, the Dorians adjacent to the Carians, Ionia, the Hellespont, the districts on the coast of Thrace, and the islands which lie between the Peloponnesus and Crete toward the east, with the exception of Melos and Thera.

Of these, the Chians, Lesbians, and Corcyraeans furnished ships, the rest infantry and money.

Such were the allies of each side and the preparations they made for the war.
