According to the constitution of the Peloponnesian league, every common action, such as a declaration of war, or the conclusion of a peace or treaty, was agreed on at a congress of the confederates. But, as there was no regular assembly of this kind, the several states sent envoys (ἄγγελοι), like the deputies (πρόβουλοι), of the Ionians, who generally remained together only for a short time. All the members had legally equal votes (ἰσόψηφοι); and the majority sometimes decided against a strong opposition; Sparta was often outvoted, Corinth being at all times willing to raise an opposition. We have, however, little information respecting the exact state of the confederacy; it is probable, from the aristocratic feelings of the Peloponnesians, that, upon the whole, authority had more weight than numbers; and for great undertakings, such as the Peloponnesian War, the assent of the chief state was necessary, in addition to the agreement of the other confederates. When the congress was summoned to Sparta, the envoys often treated with a public assembly of the Spartans. But upon the internal affairs, laws, and institutions of the allied states, the confederacy had legally no influence. It was a fundamental law that every state should, according to its ancient customs, be independent and supreme; and it is much to the credit of Sparta, that, so long as the league was in existence, she never, not even when a favourable opportunity offered, deprived any Peloponnesian state of this independence. Nor were disputes between individual states brought before the congress of the allies, which, on account of the preponderance of Sparta, would have endangered their liberty; but they were commonly either referred to the Delphian oracle, or to arbitrators chosen by both states. For disputes between citizens of different states there was an entirely free and equal intercourse of justice. The jurisdiction of the states was also absolutely exempt from foreign interference. These are the chief features of the constitution of the Peloponnesian confederacy; the only one which in the flourishing times of Greece combined extensive powers with justice, and a respect for the independence of its weaker members.
