Peace of Antalcidas
During the 6th century BCE, all of Anatolia was conquered by the Persian Achaemenid Empire, the Persians having usurped the Medes as the dominant dynasty in Iran. In 499 BCE, the Ionian city-states on the west coast of Anatolia rebelled against Persian rule. The Ionian Revolt, as it became known, though quelled, initiated the Greco-Persian Wars, which ended in a Greek victory in 449 BCE, and the Ionian cities regained their independence. By the Peace of Antalcidas (387 BCE), which ended the Corinthian War, Persia regained control over Ionia.
