Sacred War
Philip's campaign in Greece became linked with a new, fourth, Sacred War. The citizens of Amphissa in Ozolian Locris had begun cultivating land sacred to Apollo on the Crisaean plain south of Delphi; after some internal bickering the Amphictyonic council decided to declare a sacred war against Amphissa. A Thessalian delegate proposed that Philip should be made leader of the Amphictyonic forces, which therefore gave Philip a pretext to campaign in Greece; it is, however, probable that Philip would have gone ahead with his campaign anyway.
