The Delian League, founded in 477 BC, was an association of 173 Greek city-states under the leadership of Athens, whose purpose was to continue fighting the Persian Empire after the Greek victory in the Battle of Plataea at the end of the Greco–Persian Wars. The League's modern name derives from its official meeting place, the island of Delos, where congresses were held in the temple and where the treasury stood until, in a symbolic gesture, Pericles moved it to Athens in 454 BC. Shortly after its inception Athens began to exploit the League's navy for its own benefit. This behavior would frequently lead to conflict between Athens and the less powerful members of the League. By 431 BC Athens' heavy-handed control of the Delian League would prompt the outbreak of the Peloponnesian War; the League was dissolved upon the war's conclusion in 404 BC.
