Sparta and Athens were allies against Persia in the Persian War.
Sparta's serf population revolted and Athens sent a force to help the Spartans put it down. Then the Athenian soldiers started to sympathise with the serfs , so the Spartans sent them home. Relations froze. When the Athenians made an empire out of the Delian League cities it had led against the persians, it became adventurous and interfered in the affairs of the cities of the Peloponnesian League which Sparta led. Sparta asked Athens to back off, an overconfident Athens persisted and war ensued.
