Philip II of MacedonWorthington, Ian. 2008. Philip II of Macedonia. New Haven: Yale University Press, (; 382 BC – October 336 BC) was the king (basileus) of Macedon from 359 BC until his death in 336 BC.Cosmopoulos, Michael B. 1992. Macedonia: An Introduction to its Political History. Winnipeg: Manitoba Studies in Classical Civilization, p. 30 (Table 2: The Argeiad Kings). The rise of Macedon, from a kingdom initially at the periphery of classical Greek affairs, to a power that came to dominate Ancient Greece in the span of less than 25 years, was largely thanks to the character and policies of Philip. He was the father of Alexander the Great and a member of the ruling Argead dynasty that founded the kingdom of the Macedonians.

Macedon achieved domination over Greece during Philip II's reign by the reformation of the Macedonian army, including the establishment of the Macedonian phalanx, the use of combined arms tactics and his extensive use of siege engines and artillery, as well as by the use of effective diplomacy and marriage alliances. After defeating the Greek city-states of Athens and Thebes at the Battle of Chaeronea in 338 BC, Philip II led the effort to establish a federation of Greek states known as the Hellenic League, with him as the elected hegemon and commander-in-chief of Greece for a planned invasion of the Achaemenid Empire.Diodorus Sicilus, Book 16, 89. «διόπερ ἐν Κορίνθῳ τοῦ κοινοῦ συνεδρίου συναχθέντος διαλεχθεὶς περὶ τοῦ πρὸς Πέρσας πολέμου καὶ μεγάλας ἐλπίδας ὑποθεὶς προετρέψατο τοὺς συνέδρους εἰς πόλεμον. τέλος δὲ τῶν Ἑλλήνων ἑλομένων αὐτὸν στρατηγὸν αὐτοκράτορα τῆς Ἑλλάδος μεγάλας παρασκευὰς ἐποιεῖτο πρὸς τὴν ἐπὶ τοὺς Πέρσας στρατείαν...καὶ τὰ μὲν περὶ Φίλιππον ἐν τούτοις ἦν» However, his assassination by a royal bodyguard, Pausanias of Orestis, led to the immediate succession of his son Alexander, who would go on to invade the Achaemenid Empire in his father's stead.

Early life

Philip was born in either 383 or 382 BC, and was the youngest son of King Amyntas III and Eurydice of Lynkestis. He had two older brothers, Alexander II and Perdiccas III, as well as a sister named Eurynoe. Amyntas later married another woman, Gygaea, with whom he had three sons, Philip's half-brothers Archelaus, Arrhidaeus, and Menelaus.

After the assassination of Alexander II, Philip was sent as a hostage to Illyria by Ptolemy of Aloros.Howe, T. (2017), "Plain tales from the hills: Illyrian influences on Argead military development", in S. Müller, T. Howe, H. Bowden and R. Rollinger (eds.), The History of the Argeads: New Perspectives. Wiesbaden, 99–113. Philip was later held in Thebes (–365 BC), which at the time was the leading city of Greece. While in Thebes, Philip received a military and diplomatic education from Epaminondas, and lived with Pammenes, who was an enthusiastic advocate of the Sacred Band of Thebes.

In 364 BC, Philip returned to Macedon. In 359 BC, perhaps in May, Philip's other brother, King Perdiccas III, died in battle against the Illyrians. Before leaving, Perdiccas had appointed Philip as regent for his infant son Amyntas IV, but Philip succeeded in taking the kingdom for himself.

Philip's military skills and expansionist vision of Macedonia brought him early success. He first had to remedy the woes over Macedonian territory faced by his throne's government. This was a predicament that had greatly worsened through Macedonia's defeat by the Illyrians, a struggle in which King Perdiccas himself had died. The Paeonians and the Thracians had sacked and invaded the eastern regions of Macedonia, while the Athenians had landed at Methoni on the coast with a contingent under the Macedonian pretender Argaeus II.

Military career

Improvements to the army

Philip pushed back the Paeonians and Thracians promising tributes, and defeated the 3,000 Athenian hoplites (359 BC). Momentarily free from his opponents, he concentrated on strengthening his internal position and, above all, his army. Philip II made many notable contributions to the Macedonian army. The cavalry, which were the primary source of the army's strength, went from a force of 600 to 4000 from the time of the battles with the Illyrians to 334 BC. The discipline and training of the soldiers increased as well, and the Macedonian soldiers under Philip were provided with the possibility of promotion through the ranks and rewards and bonus wages for exceptional service. In addition to these changes, Philip created the Macedonian phalanx, an infantry formation that consisted of soldiers all armed with a sarissa. Philip is credited for adding the sarissa to the Macedonian army, where it soon was the common weapon used by most soldiers.

Early military career

The following year (358 BC), Philip heard that the Paeonian king, Agis, had died. Taking advantage of their political disarray and transition of power, Philip marched his army into Paeonia, where he defeated the Paeonians. He then compelled the tribe to swear allegiance to Macedon.

Philip had married Audata, daughter or granddaughter of the Illyrian king Bardylis. However, this marriage did not prevent him from marching against the Illyrians in 358 BC and defeating them at the battle of Erigon Valley, in which some 7,000 Illyrians died (357 BC). By this move, Philip established his authority inland as far as Lake Ohrid and earned the favour of the Epirotes.The Cambridge Ancient History Volume 6: The Fourth Century BC by D. M. Lewis, 1994, p. 374, : "... The victory over Bardylis made him an attractive ally to the Epirotes, who too had suffered at the Illyrians' hands, and his recent alignment ..."

After securing the western and southern borders of Macedon, Philip went on to besiege Amphipolis in 357 BC. The Athenians had been unable to conquer Amphipolis, which commanded the gold mines of Mount Pangaion, so Philip reached an agreement with Athens to lease the city to them after his conquest, in exchange for Pydna (which was lost by Macedon in 363 BC). However, after conquering Amphipolis, Philip captured Pydna for himself and kept both cities (357 BC). Athens soon declared war against him, and as a result, Philip allied Macedon with the Chalcidian League of Olynthus. He subsequently conquered Potidaea, this time keeping his word and ceding it to the League in 356 BC.

In 357 BC, Philip married the Epirote princess Olympias, who was the daughter of the king of the Molossians. Alexander was born in 356 BC, the same year as Philip's racehorse won at the Olympic Games.

During 356 BC, Philip conquered the town of Crenides and changed its name to Philippi. He then established a powerful garrison there to control its mines, which yielded much of the gold he later used for his campaigns. In the meantime, his general Parmenion defeated the Illyrians again.

In 355–354 BC, he besieged Methone, the last city on the Thermaic Gulf controlled by Athens. During the siege, Philip was injured in his right eye, which was later removed surgically. Despite the arrival of two Athenian fleets, the city fell in 354 BC. Philip also attacked Abdera and Maronea, on the Thracian coast (354–353 BC).

Third Sacred War

Philip's involvement in the Third Sacred War (356–346 BC) began in 354 BC. At the request of the Thessalian League, Philip and his army traveled to Thessaly in order to capture Pagasae, resulting in an alliance with Thebes. A year later in 353 BC, Philip was once again asked to assist in battle, but this time against the tyrant Lycophron who was supported by Onomarchus. Philip and his forces invaded Thessaly, defeating 7,000 Phocians and forcing Phayllus, the brother of Onomarchus, to leave.

That same year, Onomarchus and his army defeated Philip in two succeeding battles. Philip returned to Thessaly the next summer, this time with an army of 20,000 infantry, 3,000 cavalry, and the additional support of the Thessalian League's forces. At the Battle of Crocus Field, 6,000 Phocians fell and 3,000 were taken as prisoners and later drowned. This battle earned Philip immense prestige as well as the free acquisition of Pherae. He was made the leader (archon) of the Thessalian League and was able to claim Magnesia and Perrhaebia, which expanded his territory to Pagasae. Philip did not attempt to advance into Central Greece because the Athenians, unable to arrive in time to defend Pagasae, had occupied Thermopylae.

There were no hostilities with Athens yet, but Athens was threatened by the Macedonians. From 352 to 346 BC, Philip did not again travel south. He was active in completing the subjugation of the Balkan hill-country to the west and north, and in reducing the Greek cities of the coast as far as the Hebrus. To the chief of these coastal cities, Olynthus, Philip continued to profess friendship until its neighboring cities were in his hands.

In 348 BC, Philip started the siege of Olynthus, which, apart from its strategic position, housed his half-brothers, Arrhidaeus and Menelaus, pretenders to the Macedonian throne. Olynthus had at first allied itself with Philip, but later shifted its allegiance to Athens. The latter, however, did nothing to help the city because its expeditions were held back by a revolt in Euboea. The Macedonian king took Olynthus in 348 BC and razed the city to the ground. The same fate was inflicted on other cities of the Chalcidian peninsula, resulting in the Chalcidian League dissolving.

Macedon and the regions adjoining it having now been securely consolidated, Philip celebrated his Olympic Games at Dium. In 347 BC, Philip advanced to the conquest of the eastern districts about Hebrus, and compelled the submission of the Thracian prince Cersobleptes. In 346 BC, he intervened effectively in the war between Thebes and the Phocians, but his wars with Athens continued intermittently. However, Athens had made overtures for peace, and when Philip again moved south, peace was sworn in Thessaly.

Later campaigns (346–336 BC)

With key Greek city-states in submission, Philip II turned to Sparta, warning them "If I invade Laconia, I shall turn you out." The Spartans' laconic reply was one word: "If." Philip proceeded to invade Laconia, devastate much of it and eject the Spartans from various parts.

In 345 BC, Philip conducted a hard-fought campaign against the Ardiaioi (Ardiaei), under their king Pleuratus I, during which Philip was seriously wounded in the lower right leg by an Ardian soldier.Ashley, James R., The Macedonian Empire: The Era of Warfare Under Philip II and Alexander the Great, 359–323 BC. McFarland, 2004, p. 114,

In 342 BC, Philip led a military expedition north against the Scythians, conquering the Thracian fortified settlement Eumolpia to give it his name, Philippopolis (modern Plovdiv).

In 340 BC, Philip started the siege of Perinthus, and in 339 BC, began another siege against the city of Byzantium. As both sieges failed, Philip's influence over Greece was compromised. He successfully reasserted his authority in the Aegean by defeating an alliance of Thebans and Athenians at the Battle of Chaeronea in 338 BC, and in the same year, destroyed Amfissa because the residents had illegally cultivated part of the Crisaian plain which belonged to Delphi. These decisive victories led to Philip being recognized as the military leader of the League of Corinth, a Greek confederation allied against the Persian Empire, in 338/7 BC. Members of the league agreed never to wage war against each other, unless it was to suppress revolution.
