Political developments

Alexander’s successors

Nothing shows the personality of Alexander the Great more clearly than the way in which people who had seemed pygmies at his side now became leaders of the world he had left behind. Blood still counted: the only male relative, a mentally impaired, illegitimate son of Philip, was proclaimed king as Philip III Arrhidaeus (c. 358–317), together with Rhoxane’s son Alexander IV (323–310), born after his father’s death in August; both were mere figureheads. For the moment Antipater was confirmed in authority in Macedon and Greece. At Babylon power was shared by two senior officers, Perdiccas (c. 365–321) and Craterus (c. 370–321). By common consent, Alexander’s ongoing plans were abandoned. His generals had to be content with the office of governor. Antigonus Monophthalmos (“The One-eyed”; c. 382–301), like Antipater, was not in Babylon at the time of Alexander’s death in 323. For almost 10 years he had been governing Phrygia and had shown himself a brave soldier and competent administrator. His firmness and tact were popular with the Greek cities. Of the generals in Babylon, it was Ptolemy (c. 367/366–283) who calculated from the first that the empire would not hold together. He secured for himself the governorship of Egypt, where he aspired to set up an independent kingdom. Lysimachus (c. 360–281) was given the less attractive assignment of governing Thrace. Two of the others, noted for their physical and military prowess, Leonnatus and Seleucus, waited on events. The soldiers discounted Eumenes of Cardia, who bore the main responsibility for civil administration, but he knew more about the empire than anyone else.

An uprising by Greek mercenaries who had settled in Bactria but wanted to return to Greece was crushed. Trouble in Greece, led by the Athenians and aimed at liberating the cities from Macedonian garrisons, was tougher to control. Sparta refused to participate, as did the islands, but a coalition of Athens with Árgos, Sicyon, Elis, and Messenia, supported by Boeotians, Aetolians, and Thessalians, was a formidable challenge to Antipater’s authority. For a time Antipater was hard-pressed in Lamía (the war of 323–322 is known as the Lamian War). Leonnatus intervened, nominally in support but in fact ambitious to usurp Antipater’s power; he was killed in action, however. In the end Antipater won, Athens capitulated, and Demosthenes (the voice and symbol of anti-Macedonian feeling) committed suicide. Antipater reestablished Macedonian authority autocratically, with no nonsense about a “free” League of Corinth.

The story of the jockeying for power during the next two decades or so is inordinately complex. First Perdiccas, governing in the name of the two kings with the support of Eumenes, was charged with personal ambition and was assassinated. The armies made Antipater regent (Craterus had been killed in battle), and Antigonus, with Antipater’s son Cassander (c. 358–297) as second-in-command, was placed in charge of the armies in Asia. Ptolemy was secure in Egypt; Seleucus (c. 358–281), governor of Babylon, and Lysimachus in Thrace continued to watch and wait; and Eumenes, a non-Macedonian with a fortune behind him, could claim to represent the kings against the ambitions of generals and governors.

Then, in 319, Antipater died and was succeeded by a senior commander but maladroit politician named Polyperchon, who tried to win the Greeks of the mainland by a new proclamation of their liberties. The result was that the Athenians used their freedom to execute the pro-Macedonians, including the worthy but compromising Phocion. War flared up. Eumenes, allied with Polyperchon, challenged Antigonus and secured Babylon, but he was betrayed and killed in 316. Seleucus escaped to Egypt. Polyperchon’s position was weak, and he was soon ousted by the able, up-and-coming Cassander. In becoming master of Macedon and most of Greece, Cassander rebuilt Thebes and put the Aristotelian Demetrius of Phalerum in charge of Athens. Olympias, Alexander the Great’s terrible mother, had eliminated Philip III. Cassander had her put to death, while keeping Rhoxane and Alexander IV under his protection—or guard.

Antigonus was now the dominant figure of the old brigade. Cassander, Ptolemy, and Lysimachus formed a coalition against him. For four years (315–311) they fought indecisively. Antigonus showed himself energetic, resourceful, and imaginative, but he could not strike a decisive blow. The only major change came in the brilliant coup by which Seleucus succeeded in recovering Babylon. In 311 the four leaders agreed to divide the world, leaving Ptolemy with Egypt and Cyprus, Antigonus with Asia, Lysimachus with Thrace, and Cassander with Macedonia and Greece, but only until Alexander IV came of age in 305. Seleucus was left out.

Royal blood, however, was quickly forgotten in the pursuit of power. Cassander murdered Rhoxane and young Alexander in 310, soon after Antigonus had vainly tried to crush Seleucus. Seleucus, however, held on to a damaged Babylon and the eastern provinces, except for India, which he had to yield to the Indian king Chandragupta. Antigonus now had the effective support of his brilliant son Demetrius (336–283), known as Poliorcetes, or Besieger, who ousted the other Demetrius and restored the democracy and eventually the League of Corinth; he was hymned with divine honours and given the Parthenon as his palace. Demetrius, also in 306, crushed Ptolemy in a naval battle and secured Cyprus and the Aegean, though he failed in a famous siege of Rhodes (305–304). Antigonus and Demetrius now proclaimed themselves joint kings in succession to Alexander. Antigonus, however, failed to conquer Egypt, and the other rulers also took the title of king. Cassander, Lysimachus, Seleucus, and Ptolemy formed an alliance against Antigonus and Demetrius, and at Ipsus in 301 the allies, with the help of a force of elephants brought from India by Seleucus, defeated and killed Antigonus. Demetrius escaped, retaining Tyre and Sidon and command of the sea. Lysimachus took large portions of Anatolia; Seleucus assumed control over Mesopotamia and Syria, except for a part in the south occupied de facto by Ptolemy; and Cassander was content with Macedonia and parts of Greece.

Cassander, who was a statesman, had founded two great cities, Cassandreia and Thessalonica, as well as rebuilding Thebes. His death in 297 was a prelude to more disturbances. Demetrius conquered most of Greece and secured Macedonia in 294, but he was ousted in 288 by Lysimachus in alliance with King Pyrrhus of Epirus (319–272). Demetrius now concentrated all his forces on winning Asia and all but succeeded. He fell ill, however, and surrendered to Seleucus, who gave him every opportunity to drink himself to death. The stage was set for a confrontation between Lysimachus and Seleucus.

Ptolemy gained command of the sea by Demetrius’ fall. He died in his bed, the only one of Alexander’s successors to do so, and was succeeded peacefully by his son Ptolemy II Philadelphus (308–246). However, a son by his first wife, Ptolemy Ceraunus, the Thunderbolt (grandson of Antipater), was stirring the waters round Lysimachus, and the latter soon lost support. Seleucus defeated and killed Lysimachus, and Alexander’s empire, except for Egypt, seemed to be his for the asking. Lysimachus’s army, however, supported Ceraunus, who assassinated Seleucus in 281. Seleucus’s son by a Sogdian noblewoman succeeded him as Antiochus I (324–261). In Greece proper the strongest powers were Antigonus Gonatas (c. 320–239), son of the brilliant Demetrius and himself a man of high character, ability, and culture, and Pyrrhus, king of Epirus. Pyrrhus was about to embark on his ill-starred expedition to Italy, where he soundly defeated the growing power of Rome but at an enormous cost to himself.

At this point, migrating Celts under the command of Bolgius and Brennus caused an added complication, not least by the defeat and death of Ceraunus. Brennus pushed down into Greece but was repulsed by the Aetolians. The dangers posed by the invading Celts led, in 279, to a treaty between Antigonus and Antiochus, who agreed not to interfere in one another’s spheres of influence. Each won a decisive victory over the Celtic invaders, who eventually settled in Serbia, Thrace, and Galatia in central Anatolia. Antigonus was able to secure Macedonia. Lysimachus’s kingdom was never revived. The three centres of power were Macedonia, Syria, and Egypt.
