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<span> moved it to Athens in 454 BC.

This behavior </span>frequently<span> led to conflict between Athens and the less powerful </span>members<span> of the League. By 431 BC, Athens' </span>heavy-handed<span> control of the Delian League prompted the </span>outbreak<span> of the </span>Peloponnesian War<span>; the League was </span>dissolved<span> upon the war's conclusion in 404 BC under the direction of </span>Lysander<span>, the </span>Spartan<span> commander.</span>
