What were Athens' and Sparta's contributions to the Persian Wars?

Athens provided the main component of the war fleet which defeated the Persian fleet at Salamis, so eliminating the Persian amphibious threat to the Greek cities and allowing them to concentrate a land army at Plataia the following year to defeat the Persian army and its Greek allies. It also exposed the Persian sea supply fleet, which forced Xerxes to take half his army home before the crucial battle. Sparta provided only a few ships, its principal contribution was leadership, and at the land battle of Plataia, perhaps the most effective component of the Greek land force.
