The least obscure and longest-lasting amphictyony was the Delphic or Great Amphictyonic League that was organized to support the greater temples of Apollo and Demeter. Its council had religious authority and the power to pronounce punishments against offenders. Punishments could range from fines to expulsion and to conduct sacred wars. The Amphictyonic League also set the rules of battle so as to protect sanctuaries and impose sentences on those who molested sanctuaries. All members were obliged to pledge themselves by an oath as reported by Aeschines.
