During the last phase of this war, Athens had also fought a war with Sparta, Corinth, and their allies which also resulted in a peace treaty in 446. The Athenians defeated the Persians in Anatolia and concluded a peace treaty in 449. To pursue the war, the Athenians created the Delian League, a confederation of city-states that became the basis of an Athenian Empire.
