Corinthian War - Peace of Antalcidas (387 BC)

Peace of Antalcidas (387 BC)

Antalcidas, meanwhile, had entered into negotiations with Tiribazus, and reached an agreement under which the Persians would enter into the war on the Spartan side if the allies refused to make peace. It appears that the Persians, unnerved by certain of Athens' actions, including supporting king Evagoras of Cyprus and Akoris of Egypt, both of whom were at war with Persia, had decided that their policy of weakening Sparta by supporting its enemies was no longer useful. After escaping from the blockade at Abydos, Antalcidas attacked and defeated a small Athenian force, then united his fleet with a supporting fleet sent from Syracuse. With this force, which was soon further augmented with ships supplied by the satraps of the region, he sailed to the Hellespont, where he could cut off the trade routes that brought grain to Athens. The Athenians, mindful of their similar defeat in the Peloponnesian War less than two decades before, were ready to make peace.

In this climate, when Tiribazus called a peace conference in late 387 BC, the major parties of the war were ready to discuss terms. The basic outline of the treaty was laid out by a decree from the Persian king Artaxerxes:

King Artaxerxes thinks it just that the cities in Asia should belong to him, as well as Clazomenae and Cyprus among the islands, and that the other Greek cities, both small and great, should be left independent, except Lemnos, Imbros, and Scyros; and these should belong, as of old, to the Athenians. But whichever of the two parties does not accept this peace, upon them I will make war, in company with those who desire this arrangement, both by land and by sea, with ships and with money.

In a general peace conference at Sparta, the Spartans, with their authority enhanced by the threat of Persian intervention, secured the acquiescence of all the major states of Greece to these terms. The agreement eventually produced was commonly known as the King's Peace, reflecting the Persian influence the treaty showed. This treaty marked the first attempt at a Common Peace in Greek history; under the treaty, all cities were to be independent, a clause that would be enforced by the Spartans as guardians of the peace. Under threat of Spartan intervention, Thebes disbanded its league, and Argos and Corinth ended their experiment in shared government; Corinth, deprived of its strong ally, was incorporated back into Sparta's Peloponnesian League. After 8 years of fighting, the Corinthian war was at an end.
