In 359 two new strong rulers came to the throne, Artaxerxes III of Persia and Philip II of Macedon. The last decade of the long reign of Artaxerxes II had been blighted by revolts in the western half of his empire—at first sporadic, then concerted. Already in the late 370s Datames, the governor of Cappadocia, had established his independence. Then, by the middle of the decade, Ariobarzanes of Hellespontine Phrygia went into revolt, assisted by Timotheus of Athens and Agesilaus of Sparta. The last and greatest phase of the revolt was led by Orontes, described by the sources as satrap of Mysia. (Possibly an enclave in the Troy region of Anatolia, “Mysia” could, however, also be an error for “Armenia.” If so, the geographic spread of the insurrectionist satraps was still greater.) The other rebelling satraps were Mausolus of Caria (briefly) and Autophradates of Lydia. Some participation by local Greek cities in Anatolia is possible, though perhaps they merely followed the lead of their satrapal overlords; Athens and Sparta seem surreptitiously to have helped.

The aims of the revolt are a matter for speculation, but it looked serious for a long moment: a second and successful Cunaxa was a possibility. (One speculation sees the affair in dynastic terms: Orontes, who was well born, presented a greater danger to Artaxerxes than local men like Mausolus, whose ambitions were by definition limited. No one would follow a native Carian in an attempt on the kingship of Persia; it is significant that Mausolus returned to his allegiance so promptly.) At the date of Artaxerxes’ death in 359, the revolt was over, the traitors’ cause having been ruined by treachery among themselves. Despite setbacks, Artaxerxes II and the empire had weathered the Revolt of the Satraps.

The new king Artaxerxes III promptly ordered the satraps to dismiss their mercenary armies, thus preempting future trouble of the same sort. This was an early indication of the vigour with which he intended to rule and which was to regain Egypt for him.

In Macedon, Amyntas had eventually been succeeded by Perdiccas, the second of his sons by Eurydice. This happened in 365, after a turbulent five-year interval of two brief reigns, those of Alexander II and Ptolemy, and one intervention by a pretender, Pausanias. Perdiccas himself was killed in 359 in a catastrophic battle against the Illyrians, Macedon’s permanent enemies, and his younger brother Philip, the last of Amyntas’s sons by Eurydice, succeeded.

The achievements of Philip’s predecessors have naturally been overshadowed by his own, just as Philip’s were to be eclipsed by Alexander’s. To some extent the historical injustice is beyond redress, because the literary sources gave no systematic attention to Macedon until it was obvious that the activities of its kings were to be the determining factor in Greek history. That realization came later than 359, when Philip’s chances must have looked little better than those of his immediate predecessors; thus, there is not even proper information about Philip’s early consolidation of power.

Fortunately, Thucydides was specially interested in the north, for personal reasons, and he speaks with admiration of the way Archelaus had pulled Macedon together militarily in the last years of the 5th century. Regarding the culture, there is valuable evidence from Herodotus and from excavations, particularly those conducted in the 1970s and ’80s at Macedonian Verghina. The Macedonian kings of the 5th century were sufficiently Hellenized to compete in the Olympic Games (as Herodotus attests) and at the games for Argive Hera (as proved by a dedicated prize tripod found at Verghina). The poets Euripides and Agathon both moved to Macedon at the end of that century, and so evidently did first-rate Greek artists in the course of the next, judging from the paintings discovered in the Verghina tombs. In 1983 investigators discovered, again at Verghina, an inscription in extremely beautiful Greek lettering recording a dedication by Philip’s mother, “Eurydice daughter of Sirras,” which is further proof of the Hellenism of Macedon in this period.

Modern belief in the Greekness of the Macedonian language was strengthened by the publication in 1994 of an important curse tablet from Pella that appears provisionally to indicate that the Macedonian language was a form of northwest Greek. Macedonian religion looks Greek; there are local variations, but that is equally true of incontestably Greek places in, for instance, the Peloponnese. Many Macedonian personal names resemble Greek ones, and it has recently been suggested that such onomastic evidence indicates that the Macedonian settlers originally migrated from northern Thessalian Perrhaibia and the region around Mt. Olympus—as already suggested by a poem ascribed to the Archaic poet Hesiod.

Cultural Hellenization, however, was compatible with a social and military structure that was alien to Greek tradition, resembling instead the feudalism of later societies. (In some respects the contemporary society having most in common with Macedon was Achaemenid Persia.) The 4th-century Macedonian kings made grants of land in exchange for military service; this system is hinted at by literary sources and illustrated by inscriptions. Given the size and fertility of the areas controlled by the Macedonian kings, there was huge potential for military achievement, provided Macedon’s chronic enemies and invaders could be appeased or crushed.

Philip needed to buy time by means of the first method, appeasement, in order to build the army that would enable him to crush where appeasement failed. (Philip always preferred diplomacy to force, dissimilar in that respect to his son Alexander, whose preferences were the reverse.) Although Philip must have seemed unlucky in coming to the throne at so unpromising a moment in Macedonian history, there were in fact compensations, especially if one looks beyond such real but local enemies as the Illyrians and assumes that from the outset Philip’s vision rested on the far horizon. The greatest hoplite power in Greece, namely Sparta, was preoccupied with regaining Messenia, just as Persia was preoccupied with Egypt. Thebes had lost Epaminondas and was soon to overextend itself badly in the Third Sacred War. Athens still had a naval empire of sorts, but it was already showing signs of breakup; in any case, if Philip was to be stopped, it would not be by sea. He could and arguably did time his operations so as to make it impossible for a fleet to get at him (ships could not sail north when the Etesian winds were blowing). On the positive side, the productivity of the silver and gold mines of the Pangaion region would be a huge asset to Philip, and it was thus encouraging that they were currently controlled by a dwarf among imperial powers, Thasos. Although Thasos seems to have been extending its mainland interests remarkably in the 360s, it was not Athens and could be dealt with.

First Philip needed to reorganize his army, which he accomplished by introducing more rigorous training and employing mercenaries. This enabled him to inflict defeats on the Illyrians and other northern enemies. At the same time he made a string of advantageous “marriages,” some more official than others and scarcely amounting to more than politically slanted concubinage; one of these was to an Illyrian princess, Audata. In 357, however, all of these were effectively displaced by his marriage to the formidable Olympias, who on or about July 20, 356, gave birth to Alexander. In 358 Philip made a preliminary visit to the strategically and politically crucial area of Thessaly. He was now poised for a “blitzkrieg” against Amphipolis, which he besieged and captured in 357. Then he moved on to conquer Pydna and the mining city of Crenides, renamed Philippi (356). In 356 he formed an alliance with the Olynthians, who had good reason to be alarmed at Philip’s dazzlingly rapid progress, which continued with the taking of Potidaea in 356 and the successful siege of Methone (355–354). An inscription shows that the Olynthian alliance was recommended by the Delphic oracle, interesting evidence that the oracle was still politically active. The Olynthian alliance is a reminder that Philip was always happy to operate diplomatically if at all possible; in fact, the Athenians had been kept quiet at the time of Philip’s assault on Amphipolis by promises that he would hand it over to them. He never did. The territory of Amphipolis was distributed to Macedonian feoffees.

After the conquest of Methone came some successes in Thrace, which Athens was unable to prevent despite attempts, a little halfhearted and a little late, to strengthen the independent Thracian princes through alliances with itself. Even the great Athenian orator and statesman Demosthenes (384–322) was slow to realize that Athens’s interest required a united, not a divided, Thrace.

Athens had difficulties of its own at this time. In 357 the Social War, the war against its allies, broke out. Already in the 360s, in the aftermath of the Samian cleruchy, trouble had occurred on Ceos and elsewhere. In addition, Mausolus of Caria, once more loyal to Persia and its new king Artaxerxes III, and surely remembering Epaminondas’s example, incited Rhodes, Chios, and Byzantium to revolt against Athens (though, as stated, Byzantium was probably already detached). Dislike of Athens was as much a factor in the outbreak of war as the intriguing of Mausolus, which Demosthenes (naturally) stressed in his search for an outside scapegoat. (Mausolus’s help, however, is a fact and should not be doubted.) To Athens’s costly obsession with Amphipolis and the Chersonese should be added its various breaches of the promises made in 377. (For instance, Athens had, despite the charter, installed garrisons and cleruchies and had even levied tribute under the euphemistic name of “contributions.”) In fact, it did not even respect its most-basic political guarantees: at the end of the 360s, the Athenian commander Chares actually helped an oligarchy to power on Corcyra.

The war went badly for Athens, and it was forced to accept a disadvantageous peace in 355 when the Persian king threatened to intervene on the rebel side. It is disputed how far the inefficiency of the Athenian navy was responsible for the defeat. There are plenty of complaints by contemporary orators to the effect that the trierarchic system was not working properly. Still, there was no absolute shortage of ships, and it has been pointed out that some features denounced by orators, such as the hiring out of trierarchic obligations to third parties, actually tended to promote professionalism, because such hired trierarchs built up expertise.

Macedonian supremacy in Greece

In 353 Philip was in undisputed control of a much-enlarged Macedon. He was brought into Greece itself as a result of the Third Sacred War of 355–346. That war originated in a more or less gratuitous Theban attack on Phocis, which in 362 had refused to send a contingent for the Mantinea campaign. The time lag is to be explained in terms of power politics: the Thebans had suffered a reverse on Euboea in 357, when Theban ascendancy was suddenly and humiliatingly replaced by Athenian, and they were looking for a victim. Phocian behaviour offered an excuse. The Thebans, who since 364 had influence over the preponderance of votes in the Delphic Amphictyony, persuaded it to condemn Phocis (autumn 357) to a huge fine for the usual technical offense, “cultivation of sacred land.” The hope was that if, or rather when, Phocis was unable to pay, Thebes would be awarded the conduct of the ensuing Sacred War. It all went wrong. The Phocians seized the temple treasure in 356 and recruited a mercenary force of such size and efficiency that the Thebans could not defeat them. The Phocian leaders were Philomelus, followed by Onomarchus, Phayllus, and finally Phalaecus. The actual declaration of the Sacred War was delayed until 355, partly because it was only in that year that the relative impotence of one of Phocis’s hitherto most-impressive-looking allies, the Athenians, was revealed by the miserable end to the Social War in the Aegean.

After Philomelus’s death, Onomarchus formed alliances with the rulers of the Thessalian city of Pherae. Thessaly as a whole had been willing enough to declare war on Phocis in keeping with an enmity of immemorial antiquity already remarked on as long-standing by Herodotus in the context of the Persian Wars. Nonetheless, Thessalian unity on the one hand and Theban ability to influence events in Thessaly on the other were both less than complete, and Onomarchus evidently succeeded in exploiting this fluid situation. Yet another city, Larissa, responded by issuing an invitation that was ultimately to be disastrous to Greek, as well as merely to Thessalian, freedom. It called in Philip.

The immediate consequence, a victory for Onomarchus’s Phocians over Philip, his only defeat in the field, was totally unexpected. The Phocians seem to have had a “secret weapon,” in the form of nontorsion artillery. In the following year (352) that defeat was, however, completely reversed at the Battle of the Crocus Field. Philip, who had already perhaps been officially recognized as ruler of Thessaly before the Crocus Field, now took over Thessaly in the full sense, acquiring its ports and its revenues. A further asset was the Thessalian cavalry, which was used to augment Macedon’s own “companion cavalry” in the great battles of Alexander’s early years in Asia.

Southern Thessaly was the gateway to Greece proper, as Thermopylae had illustrated in 480 and the Spartans had recognized by their foundation of Heraclea in Trachis. A probe by Philip on Thermopylae itself was, however, firmly repelled by Athens. Philip could afford to wait and perhaps was obliged to do so by Thracian trouble closer to home (end of 352). When he laid siege to a place called Heraeum Teichos, Athens sent a small contingent in September 351. At some date not long before this, perhaps June 351, Demosthenes delivered his “First Philippic,” a denouncement of Philip and Macedonian imperialism. He decried the Athenian moves to counter Philip as always being too little and coming too late. He also urged the creation of a task force and larger emergency force. It is not clear how influential Demosthenes’ advice was—or how influential, at this stage, it deserved to be: at about the same time, and, perhaps actually after the “First Philippic,” Demosthenes was found advocating, in the “Speech on the Freedom of the Rhodians,” a foolish diversion of resources to the southeastern Aegean against the encroachments of Mausolus’s family. The situation there was, in fact, beyond repair.

In summer 349, with Etesian winds about to blow, Philip, despite the alliance of 356, attacked Olynthus, the centre of the Chalcidic Confederation. Olynthus turned to the only and obvious place for help, Athens. This was the occasion of the three “Olynthiac Orations” of Demosthenes. One of Demosthenes’ pleas was to make the reserves of the so-called Festival, or Theoric, Fund immediately available for military purposes—in fact, to finance an Olynthian expedition. There is no agreement that his stirring patriotism was correct from the point of view of policy; perhaps the decision to build up Athens’s financial resources slowly in preparation for the time when Philip had to be confronted nearer home was right. This unglamorous, though not actually dishonourable, policy is associated with the name of Eubulus, the Athenian leader of the pacifist party, whose caution helped to make possible the prosperous Athens of the time of the statesman and orator Lycurgus.

Olynthus fell in 348, despite the Athenian help that was eventually sent. Many of the inhabitants of the city were sold into slavery. Although Greek warfare always permitted this theoretically, the treatment of Olynthus was, nevertheless, shocking to Greek sentiment. In addition, there was no comfort for Athens from the events on its doorstep; Euboea, which Eubulus and his supporters agreed should always be defended, successfully revolted in 348.

At Athens, it must have seemed that there was no immediate further point in fighting, with Amphipolis and Olynthus gone; Philip, moreover, had been putting out peace feelers for some time. The Sacred War, however, brought Philip back into Greece, when desultory warfare in 347 caused the Boeotians to call him in; in alarm Phocis appealed to Athens and Sparta. The Phocian commander Phalaecus, however, unexpectedly declined to allow the Athenians and Spartans to occupy Thermopylae, and Athens was forced to make peace. This was the notorious Peace of Philocrates—notorious because of the attempts by various leading Athenian orator-politicians to saddle each other with responsibility for what was in fact an inevitability.

The Phocians surrendered to Philip, who received their Amphictyonic votes. Many individual Phocian troops, branded as temple robbers, had already fled; some of them eventually joined Timoleon in Sicily. The cities of Phocis were physically destroyed and the remaining inhabitants distributed among villages. It is doubtful whether Philip ever seriously intended any other solution to the war in its Phocian dimension. Demosthenes was later to allege that Philip at one point had a different plan—namely, to crush Thebes and save the temple robbers in Phocis. This, however, would have been an implausible renunciation of a valuable weapon, the leadership of a Sacred War. Any such threats or promises can have been no more than feints.

Philip was for the moment supreme not merely in Phocis but in Greece. Athens, as its chief concession, had to abandon claims to Amphipolis formally. It also had to enter into an alliance, as well as make peace, with Philip. This raises the interesting question of whether Philip was already thinking of a grand crusade against Persia as early as 346; some of the sources make such a claim, but they may be contaminated by hindsight. He probably was considering such a move. For one thing, the idea of punishing the Persians for their sack of Athens in 480 was not prominent before 346 but was much heard of thereafter. Moreover, Philip had triumphantly ended one religious war and demonstrated his Hellenism and suitability for the leadership of the Greeks. Nothing would be more natural than that he or his propagandists should have hit on the idea of exploiting the still greater moral appeal to the Greeks of an all-out war of revenge for Persian impiety.

In fact, the idea of a Macedonian spillage into Anatolia was a very old one indeed, and a natural one. About half a millennium earlier, the Phrygian kingdom of Midas, the predecessor of the Lydian dynasty of Croesus, had emerged as a result of a mass movement of peoples from Macedon. An Asiatic expedition is an idea that Philip could surely have thought of for himself: he did not need Isocrates to urge him, as he did in his pamphlet called the Philippus of 346, to settle the Persian empire with wandering Greeks (or resettle them: some of these wanderers must have been mercenaries rendered unemployed by Artaxerxes’ demobilization edict of about 359). Information supplied by Artabazus, a satrap who had fled to the Macedonian court at some time in the late 350s, may have been helpful to Philip. Artabazus could have told Philip—and the very young Alexander perhaps—about the complex Persian system of supplies and travel vouchers for high-ranking officials, a system revealed to historians only in 1969, with the publication of the Persepolis Fortification Tablets. In addition, Philip seems to have had contacts elsewhere in western Anatolia, for instance with Hermias of Atarneus, a fascinating minor ruler at whose court Aristotle stayed. Whatever Philip’s plans may have been, the Persian empire was not yet as debilitated or ripe for takeover as it was to be in the 330s; on the contrary, Persia suppressed revolts in Cyprus and Phoenicia in the mid-340s, and, the greatest success of all, in Egypt in 343.

In Athens after 346 there was a group who seemed to want war against Persia, and this entailed good relations with Philip. However, Demosthenes, who constantly worked against that policy, argued that Philip was untrustworthy; he pointed out that in the second half of the 340s Philip was a persistent peacebreaker, as, for instance, in the Peloponnese and on Euboea. In 344 Demosthenes even persuaded the Athenians to reject a proposed renegotiation of the peace terms offered by Philip in the person of an orator from Byzantium called Python.

Philip had preoccupations closer to Macedon in this period, which themselves make it unlikely that he wanted to upset the arrangements of 346—at least not yet. In 345 he had to deal with the Illyrians again, which he did at the expense of a bad leg wound. The strains of his intense military life had by now left their effects on his appearance. He must have looked older than his age, scarcely more than the mid-30s, because he had already lost an eye at Methone. (It is possible that a skull found in Macedonian Verghina bearing traces of a missile wound over the eye may in fact be the actual skull of Philip II of Macedon. That possibility encouraged the forensic reconstruction in 1983 of the entire head, by techniques used for rebuilding the features of unknown crash victims with a view to identification.) Philip’s leg wound of 345 did not incapacitate him completely; in 344 he had the energy to reorganize Thessaly into its four old divisions, or “tetrachies.” It helps to explain, however, why he was relatively inactive in Macedon until 342, when he made another and final move against Thrace, removing the first local recalcitrant, a ruler named Cersebleptes. From the economic as well as the political point of view, subduing the Thracian rulers was well worth the effort: the gorgeous Thracian Treasure from Rogozen in Bulgaria, discovered in 1986, consists of 165 high-grade silver and gilded vessels; one of them is inscribed “Property of Cersebleptes.”

Philip attacked the Greek city of Perinthus in 340. Perinthus was helped by Byzantium and other Greek communities, including Athens, and even by the Persian satraps (which represents the first collision between the two great powers, Macedon and Persia). Despite all Philip’s efforts (and artillery), Perinthus held out. In 340 an exasperated Philip declared war on Athens. He also switched his siege engines from Perinthus against Byzantium, but he made no easy headway there either. It is possible that the reason for Philip’s abandonment of at least the second of these sieges was not military (siege engines were now virtually irresistible when applied to their target over time) but political. Philip’s gaze was now fixed on Athens, the greater enemy and the greater prize.

The pretext for Philip’s final involvement in Greece was trivial: still another (Fourth) Sacred War, declared this time against the petty city of Amphissa. Philip, its designated leader from the first, entered Greece toward the end of 339. This perilous occasion prompted Demosthenes’ famous rallying call to Athens, reported by its author nearly a decade later in the speech “On the Crown.” He urged sending an embassy to Thebes at this moment of danger for Greece as well as for Athens. Thebes responded magnificently, and the joint Greek army took up position at Chaeronea in Boeotia. The battle, fought in August 338, settled the political future of Greece until the second-century Roman conquest. No accurate account survives of the course of the battle, but it ended in a total victory for Philip. Tradition insists (probably rightly) on the valuable contribution of Alexander on the Macedonian left and suggests (perhaps wrongly) that Philip executed a feigned retreat. The Theban Sacred Band had simply ceased to exist. Athens was treated mildly, its prisoners being allowed to return home without ransom.

Philip’s political settlement is illustrated by a speech wrongly attributed to Demosthenes and by an inscription much restored with the help of the speech. The settlement was a masterly construction, the League of Corinth (337). Philip had perhaps waited a little while for the inevitable pro-Macedonian reaction to set in inside the leading Greek cities. Only in Sparta, arrogant but powerless, was there no willingness to adjust. Philip invaded Laconia but did not interfere further than that. Thebes had to receive a garrison. Philip’s overall goal was general acquiescence and cooperation in the war against Persia, which was now a certainty. In fact, he wanted an alliance, and without doubt the arrangements of 337 secured one. To this end most of the great federations of Greece were left intact; only Athens’s naval confederacy was dissolved (though its cleruchy on Samos was retained) and, less certainly, the Aetolian League suppressed in a punitive measure.

Like the King’s Peace and the Second Athenian Confederacy, the new league guaranteed freedom and autonomy. Unlike the Athenian organization, however, the new league put the emphasis on property rights. There were specific bans on “confiscation of property, redistribution of land, cancellation of debts, or freeing of slaves with revolutionary intent.”

The real novelty of the league was the fact that it had a king at its head and garrisons at crucial places, such as Chalcis and Corinth, to maintain the peace. The military requirements made of each state were set out in detail. Philip may have borrowed some of the features of the new arrangement, such as his politic use of titles, from precedents other than the Second Athenian Confederacy. Thus, he may have absorbed a lesson about the politic use of titles in his mother’s kingdom of Epirus; although it had been ruled by kings, the officials in the confederacy over which they presided were given Greek-sounding titles such as secretary. Other examples may have been provided by Dionysius I of Syracuse and Leucon of Bosporus, who took different titles for use in different contexts (indeed, this may have suggested to Philip the expedient of avoiding royal titles when dealing with the Greeks: for them he would be general with full powers).

In fact, the 4th century saw a thorough mixing of political categories, of which Philip’s new league was a sophisticated example. A cruder example is present in a curious decree from Labranda, which begins with the words “It seemed good to Mausolus and Artemisia” (his sister and also his wife). Here, one finds combined a regular formula for a Greek city-state with a highly irregular decision-making body—namely, a Persian satrap and his incestuous wife.

Mixing of political categories, however, was unwelcome at home in Macedon. Perhaps some Macedonian soldiers, who might have preferred Athenian loot to an Athenian alliance, were puzzled about Philip’s motives. Thus, it may have been for the benefit of such doubters that, after planning his Asiatic war and sending an advance force under Attalus and Parmenio, Philip had himself depicted in a domestic Macedonian context (he would surely not have risked such a thing in Greece) as a “13th Olympian god.” (Inscriptional evidence indicates that Philip may have received cult at Philippi, but cult for such founders was well established.) Further speculation about Philip’s motive for this action, which is as remarkable in its way as anything he ever did, is unprofitable. For it was at this moment (336) that he was struck down by an assassin, whose own motives have never been ascertained.
