The Athenians and Peloponnesians had these antecedent grounds of complaint against each other: the complaint of Corinth was that her colony of Potidaea, and Corinthian and Peloponnesian citizens within it, were being besieged; that of Athens against the Peloponnesians that they had incited a town of hers, a member of her alliance and a contributor to her revenue, to revolt, and had come and were openly fighting against her on the side of the Potidaeans. For all this, war had not yet broken out: there was still truce for a while; for this was a private enterprise on the part of Corinth.

But the siege of Potidaea put an end to her inaction; she had men inside it: besides, she feared for the place. Immediately summoning the allies to Lacedaemon, she came and loudly accused Athens of breach of the treaty and aggression on the rights of Peloponnese.
