Philip of Macedon.—These kings ruling in the interior, remote from the sea, had had but little part in the wars of the Greeks. But in 359 B.C. Philip ascended the throne of Macedon, a man young, active, bold, and ambitious. Philip had three aims:

1. To develop a strong army;

2. To conquer all the ports on the coast of Macedon;

3. To force all the other Greeks to unite under his command against the Persians.

He consumed twenty-four years in fulfilling these purposes and succeeded in all. The Greeks let him alone, often even aided him; in every city he bribed partisans who spoke in his favor. "No fortress is impregnable," said he, "if only one can introduce within it a mule laden with gold." And by these means he took one after another all the cities of northern Greece.

Demosthenes.—The most illustrious opponent of Philip was the orator Demosthenes. The son of an armorer, he was left an orphan at the age of seven, and his guardians had embezzled a part of his fortune. As soon as he gained his majority he entered a case against them and compelled them to restore the property. He studied the orations of Isæus and the history of Thucydides which he knew by heart. But when he spoke at the public tribune he was received with shouts of laughter; his voice was too feeble and his breath too short. For several years he labored to discipline his voice. It is said that he shut himself up for months with head half shaved that he might not be tempted to go out, that he declaimed with pebbles in his mouth, and on the sea-shore, in order that his voice might rise above the uproar of the crowd. When he reappeared on the tribune, he was master of his voice, and, as he preserved the habit of carefully preparing all his orations, he became the most finished and most potent orator of Greece.

The party that then governed Athens, whose chief was Phocion, wished to maintain the peace: Athens had neither soldiers nor money enough to withstand the king of Macedon. "I should counsel you to make war," said Phocion, "when you are ready for it." Demosthenes, however, misunderstood Philip, whom he regarded as a barbarian; he placed himself at the service of the party that wished to make war on him and employed all his eloquence to move the Athenians from their policy of peace. For fifteen years he seized every occasion to incite them to war; many of his speeches have no other object than an attack on Philip. He himself called these Philippics, and there are three of them. (The name Olynthiacs has been applied to the orations delivered with the purpose of enlisting the Athenians in the aid of Olynthus when it was besieged by Philip.) The first Philippic is in 352. "When, then, O Athenians, will you be about your duty? Will you always roam about the public places asking one of another: What is the news? Ah! How can there be anything newer than the sight of a Macedonian conquering Athens and dominating Greece? I say, then, that you ought to equip fifty galleys and resolve, if necessary, to man them yourselves. Do not talk to me of an army of 10,000 or of 20,000 aliens that exists only on paper. I would have only citizen soldiers."

In the third Philippic (341) Demosthenes calls to the minds of the Athenians the progress made by Philip, thanks to their inaction. "When the Greeks once abused their power to oppress others, all Greece rose to prevent this injustice; and yet today we suffer an unworthy Macedonian, a barbarian of a hated race, to destroy Greek cities, celebrate the Pythian games, or have them celebrated by his slaves. And the Greeks look on without doing anything, just as one sees hail falling while he prays that it may not touch him. You let increase his power without taking a step to stop it, each regarding it as so much time gained when he is destroying another, instead of planning and working for the safety of Greece, when everybody knows that the disaster will end with the inclusion of the most remote."

At last, when Philip had taken Elatea on the borders of Bœotia, the Athenians, on the advice of Demosthenes, determined to make war and to send envoys to Thebes. Demosthenes was at the head of the embassy; he met at Thebes an envoy come from Philip; the Thebans hesitated. Demosthenes besought them to bury the old enmities and to think only of the safety of Greece, to defend its honor and its history. He persuaded them to an alliance with Athens and to undertake the war. A battle was fought at Chæronea in Bœotia, Demosthenes, then at the age of forty-eight, serving as a private hostile. But the army of the Athenians and Thebans, levied in haste, was not equal to the veterans of Philip and was thrown into rout.

The Macedonian Supremacy.—Philip, victorious at Chæronea, placed a garrison in Thebes and offered peace to Athens. He then entered the Peloponnesus and was received as a liberator among the peoples whom Sparta had oppressed. From this time he met with no resistance. He came to Corinth and assembled delegates from all the Greek states (337)[96] except Sparta.
