Phokian Confederation - Authority in from ? to 346 BC
The Phokian Confederation was a military alliance between ~22 small city states in the mountainous region of Phocis.

Due to the strategic location of Phokis - it controls the passage from Boeotia to Lokris and Thermopylai - the confederation was repeatedly under pressure from Boeotia, Thessaly and the Delphic Amphiktyony.

In 346 BC the Confederation was defeated in the so-called Third Sacred War. This defeat led to the destruction of the settlement - and opened up a route for the Macedonians to control Greece which was used by Philip II of Macedon 8 years decade later.
