The reforms proposed B. C. 230, by Agis IV., and carried, four years later, by Cleomenes, added 3,800 periœ´ci to the number of citizens, and re-divided the lands of the state between these and 15,000 selected Laconians. Debts were abolished, and the old simple and frugal customs of Lycurgus restored. Sparta was now able to defeat the forces of the Achæan League, and to draw from it, into her own alliance, most of the Peloponnesian towns out of Achaia. But Aratus, the head of the League, violated all its principles by calling in Antigonus, the Macedonian regent, and putting him in possession of Acro-Corinthus. In the battle of Sella´sia, B. C. 221, Cleomenes was defeated, and forced to take refuge at the court of Ptolemy Philopator. The League which had been created to defend the liberties of Greece, had betrayed them; and there was no longer any hope either of restoring the glories of Sparta, or of checking the overwhelming power of Macedon and Rome.
78. Antigonus died B. C. 220, and Philip, now seventeen years of age, assumed the government. The great advantages gained during the regency were soon lost by his rashness. He hastily allied himself with Hannibal against Rome, and then with Antiochus of Syria against Egypt. (See §§ [37], [59].) His first war, however, was against Ætolia, which had sprung to arms immediately upon his accession, hoping at once to overbalance its rival, Achaia, and to increase its own territories at the expense of Macedon. As early as the time of Alexander the Great, the Ætolian tribes had formed themselves into a federal republic, which occupied a similar position in central Greece to that of the Achæan League in the Peloponnesus. By the subjection or annexation of several states, it was now extended from the Ionian to the Ægean Sea. Philip overran Ætolia with great energy, captured its seat of government, and by his brilliant successes showed a military talent worthy of the early days of Macedonian conquest. But the news of a great victory gained by Hannibal at Lake Thrasyme´ne, recalled his attention to the object of his chief ambition, a war with Rome.
79. The first movement in the new war was the siege of Apollonia, a Roman colony in Illyricum. Philip hoped to drive the Romans from the western coast of Greece, and thus prepare the way for an invasion of Italy. His camp was surprised at night by Vale´rius, and he was forced to burn his ships and retreat in all haste. The Ætolians and all their allies—Sparta, Elis, and the kings of Illyricum and Pergamus—took sides with Rome, and carried the war into Macedonia, forcing Philip to ask the aid of Carthage. The Romans captured Zacynthus, Ne´sos and Œniadæ, Antic´yra in Locris, and the island of Ægina, and presented all to the Ætolians.
At this crisis, Philopœ´men, the greatest Greek of his time, became commander of the Achæan cavalry, and, two years later, the head of the League. He improved the drill and tactics of the army, and infused new spirit into the whole nation. His invasion of Elis, in concert with Philip, was unsuccessful, and the king was defeated by Sulpic´ius Galba; but, in 207 B. C., the great victory of Mantinea placed the Macedonians and Achæans on a more equal footing with the Romans. Peace was made on terms honorable to all parties.
80. Philip, spoiled by ambition, had become unscrupulous and reckless. Instead of securing what he already possessed, he continually grasped after new conquests; and disregarding the storm that was sure to burst upon him sooner or later from the west, he now turned to the east and south. He made a treaty with Antiochus the Great for a partition of the Egyptian dependencies, by which he was to receive Thrace and the western part of Asia Minor. This led at once to war with At´talus of Pergamus, an ally of Rome, as well as with Rhodes, which took the part of Egypt. His fleet was signally defeated off Chios, B. C. 201; and though he afterward gained a victory at Lade, his losses were not retrieved. He captured, however, the important islands of Samos, Thasos, and Chios, with the province of Caria, and several places in Ionia.
81. The great disaster of the war was the rupture of the treaty with Rome. That power interfered in behalf of her allies, Egypt, Rhodes, and Pergamus; and when Philip rejected all reasonable demands, she declared the peace at an end. In the second war with Rome, Greece was at first divided into three parties, some states remaining neutral, some siding with Rome, and some with Macedon. But when the consul, Fla´mini´nus, proclaimed liberty to all the Greeks, and declared himself their champion against the long detested power of Macedon, nearly every state went over to the Roman side. On the land, Macedonia was attacked by Sulpicius Galba, aided by the Illyrians and Dardanians; while by sea, a Roman fleet, increased by Rhodian and Pergamene vessels, threatened the coast. Several important towns in Eubœa were taken, but the great decisive battle was fought (B. C. 197) at Cynocephalæ, where Philip was defeated and his power utterly prostrated. He was compelled to abandon all the Greek cities which he held, either in Europe or Asia, to surrender his entire navy, and to pay a war indemnity of one thousand talents ($1,250,000).
82. In settling the affairs of Greece, the Romans subdivided the states into still smaller sections than of old, and guaranteed perfect independence to each. The two leagues of Achaia and Ætolia were, however, left to balance each other. The states were generally satisfied with the arrangement, but the Ætolians stirred up a new war in the very year of Flamininus’s departure, and called in Antiochus from Asia to their aid. He was defeated at Thermopylæ by the Romans, B. C. 191, and the great battle of Magnesia, in the following year, ended all hope of resistance to the power of Rome. The Achæan League, sustained by the wise and able management of Philopœmen, gained in power by the weakening of its rival, and now included the whole Peloponnesus, with Megaris and some other territories beyond the peninsula.
83. Philip had aided the Romans in the recent war, and had been permitted to extend his dominions over part of Thrace, and southward into Thessaly. But when peace was secured, he was required to give up all except his hereditary kingdom. Demetrius, the second son of Philip, had long been a hostage at Rome, and acted now as his father’s ambassador. The Roman Senate conceded many points, for the sake of the warm friendship which it professed for this young prince; but its favor only aroused the suspicions of his father and the jealousy of his elder brother, Per´seus. The latter forged letters to convince his father of the treason of Demetrius, and the innocent youth was put to death by order of the king. But the grief and remorse of Philip exceeded all bounds, when he learned the deception that had been practiced. He believed that he was haunted by the spirit of Demetrius, and it was agony of mind, rather than bodily illness, that soon occasioned his death.
An ancient historian remarked that there were few monarchs of whom more good or more evil could justly be said, than of Philip V. If the promise of his youth had been fulfilled, and the opportunities of his reign improved, he would have done great things for Macedonia and Greece. But his talents became obscured by drunkenness and profligacy, his natural generosity was spoiled by the habit of supreme command, and he became in later years a gloomy, unscrupulous, and suspicious tyrant.
84. Philip had designed to punish the crime of Perseus by leaving the throne to a distant relative, Antigonus; but the sudden death of the father, while Antigonus was absent from court, enabled the son to make himself king without opposition. He pursued with much diligence the policy of Philip, in preparing Macedonia for a second struggle with Rome. The revenues were increased by a careful working of the mines; the population, wasted by so many wars, was recruited by colonies of Thracians and others; and close alliances were made with the kings of Asia, and with the hardy barbarians of the north, Gauls, Illyrians, and Germans, whose aid might be invaluable when the decisive moment should arrive. But Perseus failed to unite the states of Greece, in which a large party already preferred his supremacy to that of Rome; and instead of using his treasures to satisfy and confirm his allies, he hoarded them penuriously, only to enrich his enemies at the end of the war.
