But at around that time, in 464, you have a major earthquake. You have a major earthquake in Sparta. And so it demolishes large parts of the city. And when that earthquake happens, the Spartan helots, who, I guess the best way you can view them, they are slaves, and I encourage you to read more about them. They were treated horribly. And in Sparta, the accounts are that there were seven of these helots, of these slaves, for every Spartan. 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.
