In 354 Philip conquered Methone and then advanced into Thessaly. By 352 he had reached the
pass of Thermopylae, which he did not attempt to take, because it was strongly guarded by the
Athenians. In 351 the great Athenian orator Demosthenes delivered the first of his Philippics, a
series of speeches warning the Athenians about the Macedonian menace to Greek liberty. By 348
Philip had conquered Thrace and Chalcidice. Two years later he made peace with Athens, which
had been at war with him in defense of its ally, the Chalcidian city Olynthus. Philip was next
requested by the Thebans to interfere in the sacred war against Phocis. He marched into Phocis
in 346 and destroyed its cities. Thereafter Macedonia replaced Phocis in the Amphictyonic
League, giving Philip the right to participate in Greek political affairs; in 338 the council appointed
Philip commander of the league forces. The Athenians, aroused by Demosthenes, united with the
Thebans against Philip, but their combined army was utterly defeated in 338 at the Battle of
Chaeronea. Philip's victory made him complete master of Greece. Two years later, while preparing
to invade Persia, he was assassinated.
Philip was the greatest statesman and general of his time. He laid the foundation of the
Macedonian military power employed by his son, Alexander the Great, to conquer and Hellenize
the Middle East. A treasure-filled royal tomb, believed to be Philip's, was excavated at Vergina,
near Thessaloníki, Greece, in 1977.
Battle of Chaeronea
Military engagement fought in 338 BC in which Philip II of Macedonia
defeated the Athenians and Thebans in their last struggle for Greek independence from
Macedonia. Chaeronea was located in what is now the Greek Department of Attica and Boeotia.
