The current of popular emotion was even more plainly revealed when the time came to deliver the oration, at the Attic feast of the dead, to commemorate the citizens fallen at the battle of Chæronea. The honor fell to Demosthenes, the one man whose implacable hatred to the Macedonian dynasty and all its works was known to everyone. Attempts were made in Athens to reform the terms of military service by arranging that all citizens should be called out to defend their country, and at the same time money was spent in putting the fortifications of the city in a state to resist an army composed of skilled troops and provided with the siege artillery of the time.
But care had been taken not to invite attack while Athens was yet unprepared. At the marriage feast of Ægæ appeared an Athenian deputation bringing a golden wreath to Philip and a copy of a decree, passed formally by the city, by which it undertook to surrender anyone in its jurisdiction who should dare to plot against the king. When the news of the assassination reached Athens, Demosthenes appeared in the council in festal garb, and solemnly thanked the gods for the deliverance done at Ægæ. He considered that Athens had nothing to fear from the silly youth who now was ruling over Macedon.
But Alexander showed that the great orator had not taken his enemy’s measure. By the rapidity of his actions, he checked all attempts to revolt. Suddenly appearing at the head of his army in Thessaly, he received from the Thessalian allied cities the position of commander-in-chief, as his father had done before him, and moving rapidly south, he reached Thermopylæ, where he summoned the Amphiktyons, and meeting no opposition, was declared by them guardian of the temple at Delphi. Marching farther south to Thebes, he prevented, by his presence with an overwhelming force, any anti-Macedonian movement; and when the Athenians sent a delegation to greet him, he was tactful enough not to ask for further guaranties of good behavior on the part of the city they represented.
The Hellenic league, which included all the Greek states south of Thermopylæ and all the islands which had once owned the supremacy of Athens, met again at Corinth and renewed with Alexander the same agreement that had previously been made with his father, a treaty of offensive and defensive alliance, and the chief command by land and sea was assigned to the new king, as his father’s successor. After this triumphal and peaceful progress, Alexander returned home, where his barbarian neighbors were giving trouble by revolts against his authority.
In order to bring himself in contact with the Greek opposition to Alexander, Attalus, one of the two commanders of the Macedonian army in Asia, had entered into relations with Demosthenes, only a short time after Alexander’s succession. As Cleopatra’s uncle he took a leading part in engineering a conspiracy intended to supplant Alexander by Amyntas, the young son of Perdikkas, the elder brother of Philip, who by the traditional usage of the Macedonian monarchy was entitled to succeed Philip. The success of Alexander in Greece convinced Attalus of the futility of his schemes, and he therefore tried to make advances to the young ruler. But Alexander was not to be placated, and, as a deviser of conspiracies in his own interest, he showed that he had nothing to learn from the practised hands of the Macedonian nobles.
It would have been extremely unwise for Alexander to have shown himself openly an enemy of Attalus, who enjoyed much popularity in the army. Accordingly he made a show of friendship by graciously accepting the advances of Attalus, and at the same time he despatched an associate, Hekatæus, on whom he could rely, with directions to assassinate him. The treacherous deed was made the easier, because Parmenio, joint-commander with Attalus in Asia Minor, facilitated the plans of the assassination, despite the fact that Attalus was married to his daughter. The tribal interests of a half-barbarous people had full sway among the Macedonians, so Parmenio, who had throughout his life been conscientiously loyal to the Macedonian monarchy, did not scruple to sacrifice his daughter’s husband, when it appeared that his son-in-law was plotting to supplant the regularly accepted monarch of his people.
Alexander’s difficulties were being quickly dissolved by crime and bloodshed. The Macedonians had none of the political experiences common to the free Greek communities, and assassination was regarded both as an ordinary expedient for removing opponents, and as the logical method of rounding off a policy that was complicated. With Attalus removed, Alexander could proceed, without further hesitation, to strengthen his position at home. Amyntas, the young pretender, was executed, and with him all of the relatives of Attalus and Cleopatra. In this Borgia-like program of eliminating possible claimants to the throne, only the stepbrother of Alexander, a half-witted lad, Amidæus, was spared. Later Alexander’s mother, Olympias, forced her rival, the queen-widow Cleopatra, to commit suicide.
With this orgy of crime, the reign of Alexander was ushered in, and one reads with astonishment to-day the thin and specious apologies which would excuse the young ruler, the real instigator of these atrocities. As a matter of fact he early acquired the habit of assassination; unfortunately he never unlearned it. Whatever may be argued in behalf of his people, who were uncivilized, nothing can extenuate this early exercise in crime of the pupil of Aristotle. When we survey his record of one year we perceive that hatred of his deeds must have been the test of patriotism and good citizenship among the Greek communities, who might well see in him the typical tyrant of their political theories.
Alexander’s violent preparations for a peaceful reign were successful. During his lifetime the tranquillity of Macedonia was not disturbed. Greece had been brought by the display of military supremacy to a position of servitude; all that needed to be done before he took up his father’s program for the invasion of Asia, was to bring the western tribes on his northern frontier to reason, and to force home upon them the realization of the power of Macedon.
In the spring of 335, Alexander left Amphipolis, and by a rapid march of ten days reached Mount Hæmus in the thick of a population which had never recognized the supremacy of Macedon. They tried to defend themselves in their mountain passes, but Alexander soon forced his way through, and on the top of the highest mountain, celebrated his victory by setting up a thank offering to Dionysus. He then gave his attention to various mountain tribes with whom his father had had trouble, who had never before been subjugated, but who now met a decisive defeat at his hands. An island on the Danube, where the tribesmen had placed for security their wives and children and property, proved, however, impregnable. The young king showed himself from the first a master of strategy, for although he could not capture the island, he executed rapid movements along the river, beating the Getæ who were defending the passages, and when the Triballi had come to terms, he marched up the Danube, and then, crossing the eastern passes of the Hæmus range, returned to Pæonia.
