Athens and Sparta conflict

As the Athenian fight against the Persian empire waned, conflict grew between Athens and Sparta. Suspicious of the increasing Athenian power funded by the Delian League, Sparta offered aid to reluctant members of the League to rebel against Athenian domination. These tensions were exacerbated in 462 BC when Athens sent a force to aid Sparta in overcoming a helot revolt, but this aid was rejected by the Spartans.
