[00:00:00]In 464 BC, an earthquake struck Sparta so violently that Diodorus Siculus records only five houses in the entire city [music] were left standing. Ancient sources estimate 20,000 Spartans perished. The Agoge training halls collapsed on the young men inside. An entire generation of warriors was buried in a few brief moments of terror. The Helots saw their moment. Within days, the largest Helot revolt in Spartan history erupted [music] across Messenia.

[00:00:27]Sparta, with its army shattered, could not contain it alone.

[00:00:31]Sparta did something it had never done.

[00:00:33]It asked Athens for help. Athens [music] sent 4,000 hoplites under Cimon. Then Sparta, suspecting Athenian motives, sent them home. The insult was deliberate. That dismissal fractured the Greek [music] alliance. Within 15 years, Athens and Sparta were marching against [music] one another. The Peloponnesian War began in part from an earthquake and an insult. Subscribe to the Kronos Catalog for more historical [music] content.
