The Peace of Nicias

There are two types of successful peace treaty. The first is possible if one side has been completely defeated and can no longer recover. In that case, the victor can dictate terms that will never be challenged (e.g., the end of the Second World War). The second type is possible when all parties are involved, understand the political and military realities, see their vital interests respected, and are willing to negotiate on minor points (e.g., the Peace of Westphalia or the Congress of Vienna).

The Peace of Nicias did not belong to these categories. Sparta had gone to war to put an end to Athenian supremacy but the Delian League was still alive; moreover, at Sphacteria it had become clear that Sparta was not invincible. However, although Athens had won the war, it had not destroyed Sparta, which was still a powerful state. Moreover, not all parties that had been involved agreed to the treaty. For example, Sparta's ally Thebes refused to agree, and the inhabitants of Amphipolis, who were supposed to return to the Athenian alliance, were not willing to do so. Sparta made promises that it could not keep. Moreover, it betrayed its allies Corinth and Megara, because it accepted the Athenian occupation of territories that belonged to these cities.

Almost immediately after the treaty had been signed, it collapsed. Corinth embarked upon an ambitious diplomatic offensive that was directed against Sparta; Thebes simply refused to sign; Sparta was unable to give back Amphipolis, and Athens did not return Pylos. As a result of these tensions, the Athenians accepted Alcibiades' advice to join the coalition of the democratic states Argos, Mantinea, and Elis. Athens now had allies on the Peloponnese, and it may have looked as if the Spartan alliance, the Peloponnesian League, was about to collapse.

Below, you can read the text of the treaty, which has been included in Thucydides' History of the Peloponnesian War (5.18.1-19.2, 23.1-24.1; Rex Warner's translation). There are two texts: the real treaty that ended the war, and a document in which Sparta and Athens concluded a defensive alliance.

The oath shall be the most binding one that exists in each city, and seventeen representatives on each side are to swear it. The words of the oath shall be these: "I shall abide by the terms of the treaty honestly and sincerely." In the same way, the Spartans and their allies shall take an oath to the Athenians. This oath is to be renewed annually by both sides.
• Pillars are to be set up at Olympia, Pythia, the Isthmus, in the Acropolis at Athens, and in the temple at Amyclae in Lacedaemon.
