 This strategic location of Kirra allowed its citizens to rob pilgrims on their way to the Delphic Oracle.This behavior prompted many of the other tribal entities of the adjacent regions to form the Amphictionic League, an alliance for the protection of the cult of Demeter in Anthele (initially) and of Apollo in Delphi.The Amphictyony consulted the oracle for advice on dealing with Kirra, and the reply was a call for war.
