Treaty of Antalcidas

Antalcidas was a Spartan soldier and diplomatist sent to Tiribazus, Persian satrap of Sardis, in 393-392 B.C. to undermine the friendly relations then existing between Athens and Persia, offering to recognize Persian claims to the whole of Asia Minor.

The Athenians sent an embassy under Conon to counteract his efforts. Tiribazus, who was favourable to Sparta, threw Conon into prison, but Artaxerxes II (Mnemon) disapproved and recalled his satrap.

In 388 BC Antalcidas, then commander of the navy went to the active assistance of Persia against Athens. The success of his naval operations in the neighborhood of the Hellespont was such that Athens was glad to accept terms of peace, especially as Artaxerxes II forced them to come to terms and sign the treaty which is known as the Treaty of Antalcidas, the Peace of Altalcidas, or the ‘Universal Peace’.

The terms were that the whole of Asia Minor, with the islands of Clazomenae and Cyprus, was recognized as subject to Persia. All other Greek cities -- so far they were not under Persian rule -- were to be independent, except Lemnos, Imbros and Scyros, which were to belong, as formerly, to the Athenians. It in effect set the boundaries of Greek and Persian territory.

The terms were announced to the Greek envoys at Sardis in the winter of 387/386 BC, and were finally accepted by Sparta in 386.
