Aristagoras was the main orchestrator of the Ionian Revolt on secret instruction by Histiaeus, when the latter learned of Persian plans to interfere directly in Miletus. Aristagoras took advantage of Greek dissatisfaction with Persian rule to incite an alliance of the Greek poleis of Ionia. Soliciting assistance from the states of mainland Greece he failed to obtain the help of a major state, Sparta. He did obtain the half-hearted assistance of Athens. Their attack on the satrapy of Lydia having been defeated, they withdrew, abandoning Aristagoras to his fate.
