And so the helots start a revolt, and Sparta goes to the other city-states of Greece and says, help us, put down this revolt that happened right after our earthquake. And so Athens agrees. They send 4,000 citizen soldiers to Sparta, these citizen soldiers, the famous hoplites, to help put down the revolt. But once again, Sparta is feeling insecure. They say, hey, why did they send these soldiers? Maybe they say they want to put down this rebellion, but we Sparta, we're kind of in a fairly vulnerable state right here, what if the Athenians took the side of the helots? Well, then they might be able to take over Sparta.
