Battle of Crocus Field
The Third Sacred War (often just called 'the' Sacred War) broke out in 356 BC, and would present Philip with his first real opportunity to expand his influence into the affairs of central and southern Greece. The war was caused by the refusal of the Phocian Confederation to pay a fine imposed on them in 357 BC by the Amphictyonic League, a pan-Greek religious organisation which governed the most sacred site in Ancient Greece, the Temple of Apollo at Delphi. Behind the religious element, there probably lay a display of "realpolitik" in bringing charges against the Phocians, instigated by the Thebans. At this time, Thebes controlled a majority of the votes in the council, and at the autumn meeting in 357 BC, the Thebans were able to have both the Phocians (for the cultivation of the sacred land) and the Spartans (for occupying Thebes some 25 years previously) denounced and fined. Since the fines for both parties were "unjustifiably harsh", the Thebans probably expected neither party to pay, and thus to be able to declare a "sacred war" on either.
Third Mithridatic War
The period between the Second and Third wars of Rome and the Pontic Kingdom (81–75 BC) is discussed under the Kingdom of Pontus. There it can be seen how the long piracy wars were a development out of the First Mithridatic War and especially of the alliance between Mithridates VI and Sertorius, which in joining those two threats into a unity much larger than its parts had the serious potential of overturning Roman power. The immediate cause of the Third War was the bequest to Rome by King Nicomedes IV of Bithynia of his kingdom upon his death (74 BC).
