In 359 BC, Philip II of Macedon consulted the Oracle and was told: (above)
The king then sought to control the silver mines in the neighbouring Thracian and Illyrian kingdom, and using them to bribe his way to early victories, playing one Greek state off against the others, and isolating his enemies by bribes to potential allies.
Philip also had a highly spirited black colt that no one could ride. The Oracle of Delphi stated whoever could ride this horse would conquer the world, but despite many attempts neither Philip nor any of his generals could mount the horse. His son, Alexander, later to be called the Great, succeeded as he realized that the horse was afraid of his own shadow. Philip gave the horse Bucephalus to Alexander, who took the steed on his conquest of Asia.
In 353 BC, a third Sacred War broke out when Thebes had placed a fine upon Phokis, and Phokis, to pay for the war, heavily taxed the people of nearby Delphi and seized the Treasury of Delphi. The Amphictyonic League led by Philip declared war against Phokis. Philip sought to unite all Greece with Macedon in the Amphictyonic League to attack Persia. In 339 BC, Philip interfered once again against the Amphictyonic alliance when the Krissans trespassed on Apollo's sacred grounds. Philip punished the Krissans, and consequently in 338 c. B.C. defeated the combined armies of the Athenians and the Spartans, thus becoming the dominant force in Greek affairs. Eventually, at the Battle of Chaeronea he was successful against the Athenians and Thebans but he was assassinated before he could lead the invasion of Persia.
