This peace—negotiated during the autumn and winter succeeding the defeat of the Athenians at Amphipolis, wherein both Kleon and Brasidas were slain—resulted partly from the extraordinary anxiety of the Spartans to recover their captives who had been taken at Sphakteria, partly from the discouragement of the Athenians, leading them to listen to the peace-party who acted with Nikias. The general principle adopted for the peace was, the restitution by both parties of what had been acquired by war, yet excluding such places as had been surrendered by capitulation: according to which reserve the Athenians, while prevented from recovering Platæa, continued to hold Nisæa, the harbor of Megara. The Lacedæmonians engaged to restore Amphipolis to Athens, and to relinquish their connection with the revolted allies of Athens in Thrace; that is, Argilus, Stageirus, Akanthus, Skôlus, Olynthus, and Spartôlus. These six cities, however, were not to be enrolled as allies of Athens unless they chose voluntarily to become so, but only to pay regularly to Athens the tribute originally assessed by Aristeidês, as a sort of recompense for the protection of the Ægean sea against private war or piracy. Any inhabitant of Amphipolis or the other cities, who chose to leave them, was at liberty to do so, and to carry away his property. Farther, the Lacedæmonians covenanted to restore Panaktum to Athens, together with all the Athenian prisoners in their possession. As to Skiônê, Torônê, and Sermylus, the Athenians were declared free to take their own measures. On their part, they engaged to release all captives in their hands, either of Sparta or her allies; to restore Pylus, Kythêra, Methônê, Pteleon, and Atalantê; and to liberate all the Peloponnesian or Brasidean soldiers now under blockade in Skiônê.

Provision was also made, by special articles, that all Greeks should have free access to the sacred Pan-Hellenic festivals, either by land or sea; and that the autonomy of the Delphian temple should be guaranteed.

The contracting parties swore to abstain in future from all injury to each other, and to settle by amicable decision any dispute which might arise.[1]

Lastly, it was provided that if any matter should afterwards occur as having been forgotten, the Athenians and Lacedæmonians might by mutual consent amend the treaty as they thought fit. So prepared, the oaths were interchanged between seventeen principal Athenians and as many principal Lacedæmonians.

Earnestly bent as Sparta herself was upon the peace, and ratified as it had been by the vote of a majority among her confederates, still, there was a powerful minority who not only refused their assent but strenuously protested against its conditions. The Corinthians were discontented because they did not receive back Sollium and Anaktorium; the Megarians, because they did not regain Nisæa; the Bœotians, because Panaktum was to be restored to Athens: the Eleians also on some other ground which we do not distinctly know. All of them, moreover, took common offence at the article which provided that Athens and Sparta might, by mutual consent, and without consulting the allies, amend the treaty in any way that they thought proper.[2] Though the peace was sworn, therefore, the most powerful members of the Spartan confederacy remained all recusant.

So strong was the interest of the Spartans themselves, however, that having obtained the favorable vote of the majority, they resolved to carry the peace through, even at the risk of breaking up the confederacy. Besides the earnest desire of recovering their captives from the Athenians, they were farther alarmed by the fact that their truce for thirty years concluded with Argos was just now expiring. They had indeed made application to Argos for renewing it, through Lichas the Spartan proxenus of that city. But the Argeians had refused, except upon the inadmissible condition that the border territory of Kynuria should be ceded to them: there was reason to fear therefore that this new and powerful force might be thrown into the scale of Athens, if war were allowed to continue.[3]

Accordingly, no sooner had the peace been sworn than the Spartans proceeded to execute its provisions. Lots being drawn to determine whether Sparta or Athens should be the first to make the cessions required, the Athenians drew the favorable lot: an advantage so very great, under the circumstances, that Theophrastus affirmed Nikias to have gained the point by bribery. There is no ground for believing such alleged bribery; the rather, as we shall presently find Nikias gratuitously throwing away most of the benefit which the lucky lot conferred.[4]

The Spartans began their compliance by forthwith releasing all the Athenian prisoners in their hands, and despatching Ischagoras with two other envoys to Amphipolis and the Thracian towns. These envoys were directed to proclaim the peace as well as to enforce its observance upon the Thracian towns, and especially to command Klearidas, the Spartan commander in Amphipolis, that he should surrender the town to the Athenians. But on arriving in Thrace, these envoys met with nothing but unanimous opposition: and so energetic were the remonstrances of the Chalkidians, both in Amphipolis and out of it, that even Klearidas refused obedience to his own government, pretending that he was not strong enough to surrender the place against the resistance of the Chalkidians. Thus completely baffled, the envoys returned to Sparta, whither Klearidas thought it prudent to accompany them, partly to explain his own conduct, partly in hopes of being able to procure some modification of the terms. But he found this impossible, and he was sent back to Amphipolis with peremptory orders to surrender the place to the Athenians, if it could possibly be done; if that should prove beyond his force, then to come away, and bring home every Peloponnesian soldier in the garrison. Perhaps the surrender was really impracticable to a force no greater than that which Klearidas commanded, since the reluctance of the population was doubtless obstinate. At any rate, he represented it to be impracticable: the troops accordingly came home, but the Athenians still remained excluded from Amphipolis, and all the stipulations of the peace respecting the Thracian towns remained unperformed. Nor was this all. The envoys from the recusant minority (Corinthians and others), after having gone home for instructions, had now come back to Sparta with increased repugnance and protest against the injustice of the peace, so that all the efforts of the Spartans to bring them to compliance were fruitless.[5]

The latter were now in serious embarrassment. Not having executed their portion of the treaty, they could not demand that Athens should execute hers: and they were threatened with the double misfortune of forfeiting the confidence of their allies without acquiring any one of the advantages of the treaty. In this dilemma they determined to enter into closer relations, and separate relations, with Athens, at all hazard of offending their allies. Of the enmity of Argos, if unaided by Athens, they had little apprehension; while the moment was now favorable for alliance with Athens, from the decided pacific tendencies reigning on both sides, as well as from the known philo-Laconian sentiment of the leaders Nikias and Lachês. The Athenian envoys had remained at Sparta ever since the swearing of the peace, awaiting the fulfilment of the conditions; Nikias or Lachês, one or both, being very probably among them. When they saw that Sparta was unable to fulfil her bond, so that the treaty seemed likely to be cancelled, they would doubtless encourage, and perhaps may even have suggested, the idea of a separate alliance between Sparta and Athens, as the only expedient for covering the deficiency; promising that under that alliance the Spartan captives should be restored. Accordingly, a treaty was concluded between the two, for fifty years; not merely of peace, but of defensive alliance. Each party pledged itself to assist in repelling any invaders of the territory of the other, to treat them as enemies, and not to conclude peace with them without the consent of the other. This was the single provision of the alliance, with one addition, however, of no mean importance, for the security of Lacedæmon. The Athenians engaged to lend their best and most energetic aid in putting down any rising of the Helots which might occur in Laconia. Such a provision indicates powerfully the uneasiness felt by the Lacedæmonians respecting their serf-population: but at the present moment it was of peculiar value to them, since it bound the Athenians to restrain, if not to withdraw, the Messenian garrison of Pylos, planted there by themselves for the express purpose of provoking the Helots to revolt.

An alliance with stipulations so few and simple took no long time to discuss. It was concluded very speedily after the return of the envoys from Amphipolis, probably not more than a month or two after the former peace. It was sworn to by the same individuals on both sides; with similar declaration that the oath should be annually renewed, and also with similar proviso that Sparta and Athens might by mutual consent either enlarge or contract the terms, without violating the oath.[6] Moreover, the treaty was directed to be inscribed on two columns: one to be set up in the temple of Apollo at Amyklæ, the other in the temple of Athênê, in the acropolis of Athens.
