History of the Peloponnesian War

After the conclusion of the fifty years' truce and of the subsequent alliance, the embassies from Peloponnese which had been summoned for this business returned from Lacedaemon.

The rest went straight home, but the Corinthians first turned aside to Argos and opened negotiations with some of the men in office there, pointing out that Lacedaemon could have no good end in view, but only the subjugation of Peloponnese, or she would never have entered into treaty and alliance with the once detested Athenians, and that the duty of consulting for the safety of Peloponnese had now fallen upon Argos, who should immediately pass a decree inviting any Hellenic state that chose, such state being independent and accustomed to meet fellow-powers upon the fair and equal ground of law and justice, to make a defensive alliance with the Argives; appointing a few individuals with plenipotentiary powers, instead of making the people the medium of negotiation, in order that, in the case of an applicant being rejected, the fact of his overtures might not be made public. They said that many would come over from hatred of the Lacedaemonians.

After this explanation of their views the Corinthians returned home.

The persons with whom they had communicated reported the proposal to their government and people, and the Argives passed the decree and chose twelve men to negotiate an alliance for any Hellenic state that wished it, except Athens and Lacedaemon, neither of which should be able to join without reference to the Argive people.

Argos came in to the plan the more readily because she saw that war with Lacedaemon was inevitable, the truce being on the point of expiring; and also because she hoped to gain the supremacy of Peloponnese. For at this time Lacedaemon had sunk very low in public estimation because of her disasters, while the Argives were in a most flourishing condition, having taken no part in the Attic war, but having on the contrary profited largely by their neutrality.

The Argives accordingly prepared to receive into alliance any of the Hellenes that desired it.
