The Battle of Plataea eliminated Persian influence (and their attempt at an invasion) in Greece. The battle was a fight between the Delian League, an alliance of the most powerful Greek city-states, like Athens, Sparta, and Corinth, against the invasion force of the Persians. The Persians struggled to defeat the Greek army unit known as the 'phalanx,' a collection of warriors who banded tightly together with shields and long spears that were very difficult to fight against.
