Clazomenae was attacked by the Lydian king Alyattes in the 6th century.[2] During the 5th century it was for some time subject to the Athenians, but about the middle of the Peloponnesian War (412 BC) it revolted. After a brief resistance, however, it again acknowledged the Athenian supremacy, and repelled a Lacedaemonian attack. In 387 BC Klazomenai and other cities in Asia were taken over by Persia, but the city continued to issue its own coins.
