Peace of Antalcidas
The victories of the Greeks during the great Persian war and the liberation of Thrace, Macedon, and Ionia from the Persian Empire had the effect of enfranchising their kinsmen on the other side of the Aegean; and the Battle of Mycale (479 BC), in which the defeat of the Persians was in great measure owing to the Ionians, secured their emancipation. They henceforth became the dependent allies of Athens (see Delian League), though still retaining their autonomy, which they preserved until the Peace of Antalcidas in 387 BC once more placed them as well as the other Greek cities in Asia under the nominal dominion of Persia.
