Peloponnesian League
A competing coalition of Greek city-states centred around Sparta arose, and became more important as the external Persian threat subsided. This coalition is known as the Peloponnesian League. However, unlike the Hellenic League and the Delian League, this league was not a response to any external threat, Persian or otherwise: it was unabashedly an instrument of Spartan policy aimed at Sparta's security and Spartan dominance over the Peloponnese peninsula. The term "Peloponnesian League" is a misnomer. It was not really a "league" at all. Nor was it really "Peloponnesian". There was no equality at all between the members, as might be implied by the term "league". Furthermore, most of its members were located outside the Peloponnese Peninsula. The terms "Spartan League" and "Peloponnesian League" are modern terms. Contemporaries instead referred to "Lacedaemonians and their Allies" to describe the "league".
