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.

Henry of Anjou was crowned King Henry III of France in 1575, at Reims, but hostilities—the Fifth War—had already flared up again. Henry soon found himself in the difficult position of trying to maintain royal authority in the face of feuding warlords who refused to compromise. In 1576, the King signed the Edict of Beaulieu, granting minor concessions to the Calvinists, but a brief Sixth Civil War took place in 1577. Henry I, Duke of Guise, formed the Catholic League to protect the Catholic cause in France. Further hostilities—the Seventh War (1579–1580)—ended in the stalemate of the Treaty of Fleix.
