These were the allies of Lacedaemon: all the Peloponnesians within the Isthmus except the Argives and Achaeans, who were neutral; Pellene being the only Achaean city that first joined in the war, though her example was afterwards followed by the rest.

Outside Peloponnese the Megarians, Locrians, Boeotians, Phocians, Ambraciots, Leucadians, and Anactorians.
Of these, ships were furnished by the Corinthians, Megarians, Sicyonians, Pellenians, Eleans, Ambraciots, and Leucadians; and cavalry by the Boeotians, Phocians, and Locrians.

The other states sent infantry.

This was the Lacedaemonian confederacy.

That of Athens comprised the Chians, Lesbians, Plataeans, the Messenians in Naupactus, most of the Acarnanians, the Corcyraeans, Zacynthians, and some tributary cities in the following countries, viz., Caria upon the sea with her Dorian neighbours, Ionia, the Hellespont, the Thracian towns, the islands lying between Peloponnese and Crete towards the east, and all the Cyclades except Melos and Thera.
