Background

The Balkan campaign of Alexander the Great occurred during 335 BC against the vassal states of Macedonia. Each rebellious Greek state would be subsequently subdued by Alexander thus freeing up his position to begin his planned invasion of Persia. The Balkan campaign began following the assassination of Philip II of Macedon by the captain of his guard named Pausanias in 336 BC. Following this Alexander III of Macedon was crowned king of Macedon and became leader of the military.

However, news of Philip II's death led many city-states to believe they could throw off the Macedonian yolk and thus began asserting their independence against the new king. These states included Thebes, Athens, Thessaly as well as some Thracian tribes to the north of Macedon itself. Alexander though, would have none of it.

He gathered his army of 3,000 cavalry and rode south towards Thessaly first. Here he found the Thessalian army blocking the route between Mount Olympus and Mount Ossa. This first attack against the Thessalian army would characterize Alexander's ingenuity and innovativeness for years to come. He ordered his soldiers to ride through while the enemy was sleeping and when they awoke they suddenly found the Macedonians at their rear. After seeing the Macedonian cavalry behind them the Thessalians surrendered and decided to join Alexander's cavalry force as he continued to ride south towards the Peloponnese.

Following this initial victory Alexander and company rode south to Thermopylae where he was recognized as leader of the Sacred League. From here he headed south towards Corinth. At Corinth he sued for peace and pardoned anyone involved with the rebellion. Upon this victory he was proclaimed Hegemon of the Greek forces to command against the Persian Empire. However, while down in Corinth he received word that the Thracian tribes in the north began rebelling as well.

Battle of Mount Haemus (335 BCE)

See Battle of Mount Haemus (335 BCE)

Prior to crossing into Asia Minor, Alexander wanted to reinforce his northern borders and advanced initially into Thrace in the spring of 335 BC. The rebellion was led by the Illyrians and the Triballi that were vassals of the Macedonians prior to this.

Siege of Pelium (335 BCE)

See Siege of Pelium (335 BCE)

The Siege of Pelium was a siege engaged by Alexander the Great to conquer the Illyrian tribes of modern day Albania. It was necessary for Alexander to capture this point as it provided easy access to both Illyria and Macedonia and he needed to move quickly to quash the Greece rebellion brewing in Athens and Thebes. The success of this siege would foreshadow much of the later success Alexander would have in his subsequent campaigns. After taking the city of Pelium the Macedonians would march south to quickly bring the rest of the Greek city-states within their control.

Battle of Thebes (335 BCE)

See Battle of Thebes (335 BCE)

The Battle of Thebes was a major battle of the Balkan campaign that occurred in 335 BC between the Macedonian army and the city-state of Thebes. After being made Hegemon of the League of Corinth the Macedonian army under Alexander marched north to handle rebellions in Illyria and Thrace. Alexander never had intentions to destroy the city of Thebes however, after several emissaries failed to deliver successful terms the Macedonian army eventually destroyed the entire city.

Ancient Sources

Arrian - The Anabasis of Alexander Book I, Chapter I

It is said that Philip died when Pythodemus was archon at Athens, and that his son Alexander, being then about twenty years of age, marched into Peloponnesus as soon as he had secured the regal power. There he assembled all the Greeks who were within the limits of Peloponnesus, and asked from them the supreme command of the expedition against the Persians, an office which they had already conferred upon Philip. He received the honour which he asked from all except the Lacedaemonians, who replied that it was an hereditary custom of theirs, not to follow others but to lead them. The Athenians also attempted to bring about some political change; but they were so alarmed at the very approach of Alexander, that they conceded to him even more ample public honours than those which had been bestowed upon Philip. He then returned into Macedonia and busied himself in preparing for the expedition into Asia.

However, at the approach of spring (b.c. 335), he marched towards Thrace, into the lands of the Triballians and Illyrians, because he ascertained that these nations were meditating a change of policy; and at the same time, as they were lying on his frontier, he thought it inexpedient, when he was about to start on a campaign so far away from his own land, to leave them behind him without being entirely subjugated. Setting out then from Amphipolis, he invaded the land of the people who were called independent Thracians, keeping the city of Philippi and mount Orbelus on the left. Crossing the river Nessus, they say he arrived at mount Haemus on the tenth day. Here, along the defiles up the ascent to the mountain, he was met by many of the traders equipped with arms, as well as by the independent Thracians, who had made preparations to check the further advance of his expedition by seizing the summit of the Haemus, along which was the route for the passage of his army. They had collected their waggons, and placed them in front of them, not only using them as a rampart from which they might defend themselves, in case they should be forced back, but also intending to let them loose upon the phalanx of the Macedonians, where the mountain was most precipitous, if they tried to ascend. They had come to the conclusion that the denser the phalanx was with which the waggons rushing down came into collision, the more easily would they scatter it by the violence of their fall upon it.

But Alexander formed a plan by which he might cross the mountain with the least danger possible; and since he was resolved to run all risks, knowing that there were no means of passing elsewhere, he ordered the heavy-armed soldiers, as soon as the waggons began to rush down the declivity, to open their ranks, and directed that those whom the road was sufficiently wide to permit to do so should stand apart, so that the waggons might roll through the gap; but that those who were hemmed in on all sides should either stoop down together or even fall flat on the ground, and lock their shields compactly together, so that the waggons rushing down upon them, and in all probability by their very impetus leaping over them, might pass on without injuring them. And it turned out just as Alexander had conjectured and exhorted. For some of the men made gaps in the phalanx, and others locked their shields together. The waggons rolled over the shields without doing much injury, not a single man being killed under them. Then the Macedonians regained their courage, inasmuch as the waggons, which they had excessively dreaded, had inflicted no damage upon them. With a loud cry they assaulted the Thracians. Alexander ordered his archers to march from the right wing in front of the rest of the phalanx, because there the passage was easier, and to shoot at the Thracians where they advanced. He himself took his own guard, the shield-bearing infantry and the Agrianians. and led them to the left. Then the archers shot at the Thracians who sallied forward, and repulsed them; and the phalanx, coming to close fighting, easily drove away from their position men who were light-armed and badly equipped barbarians. The consequence was, they no longer waited to receive Alexander marching against them from the left, but casting away their arms they fled down the mountain as each man best could. About 1,500 of them were killed; but only a few were taken prisoners on account of their swiftness of foot and acquaintance with the country. However, all the women who were accompanying them were captured, as were also their children and all their booty.

Diodorus Siculus - Bibliotheca historica Book XVII

Alexander knew that many of the Greeks were anxious to revolt, and was seriously worried. In Athens, where Demosthenes kept agitating against Macedon, the news of Philip's death was received with rejoicing, and the Athenians were not ready to concede the leading position among the Greeks to Macedon. They communicated secretly with Attalus and arranged to co‑operate with him, and they encouraged many of the cities to strike for their freedom.

The Aetolians voted to restore those of the Acarnanians who had experienced exile because of Philip. The Ambraciots were persuaded by one Aristarchus to expel the garrison placed in their city by Philip and to transform their government into a democracy. Similarly, the Thebans voted to drive out the garrison in the Cadmeia and not to concede to Alexander the leader­ship of the Greeks. The Arcadians alone of the Greeks had never acknowledged Philip's leader­ship nor did they now recognize that of Alexander. Otherwise in the Peloponnese the Argives and Eleians and Lacedaemonians, with others, moved to recover their independence.​6 Beyond the frontiers of Macedonia, many tribes moved toward revolt and a general feeling of unrest swept through the natives in that quarter.

But, for all the problems and fears that beset his kingdom on every side, Alexander, who had only just reached manhood, brought everything into order impressively and swiftly. Some he won by persuasion and diplomacy, others he frightened into keeping the peace,​ but some had to be mastered by force and so reduced to submission.

First he dealt with the Thessalians, reminding them of his ancient relation­ship to them through Heracles and raising their hopes by kindly words and by rich promises as well, and prevailed upon them by formal vote of the Thessalian League to recognize as his the leader­ship of Greece which he had inherited from his father.​ Next he won over the neighbouring tribes similarly, and so marched down to Pylae, where he convened the assembly of the Amphictyons and had them pass a resolution granting him the leader­ship of the Greeks. He gave audience to the envoys of the Ambraciots and, addressing them in friendly fashion, convinced them that they had been only a little premature in grasping the independence that he was on the point of giving them voluntarily.

In order to overawe those who refused to yield otherwise, he set out at the head of the army of the Macedonians in full battle array. With forced marches he arrived in Boeotia and encamping near the Cadmeia threw the city of the Thebans into a panic. As the Athenians immediately learned that the king had passed into Boeotia, they too abandoned their previous refusal to take him seriously. So much the rapid moves and energetic action of the young man shook the confidence of those who opposed him. 6 The Athenians, accordingly, voted to bring into the city their property scattered throughout Attica and to look to the repair of their walls, but they also sent envoys to Alexander, asking forgiveness for tardy recognition of his leader­ship.

Even Demosthenes was included among the envoys; he did not, however, go with the others to Alexander, but turned back at Cithaeron and returned to Athens, whether fearful because of the anti-Macedonian course that he had pursued in politics, or merely wishing to leave no ground of complaint to the king of Persia. He was generally believed to have received large sums of money from that source in payment for his efforts to check the Macedonians, and indeed Aeschines is said to have referred to this in a speech when he taunted Demosthenes with his venality: "At the moment, it is true, his extravagance has been glutted by the king's gold, but even this will not satisfy him; no wealth has ever proved sufficient for a greedy character."​Alexander addressed the Athenian envoys kindly and freed the people from their acute terror.

Then he called a meeting at Corinth of envoys and delegates, and when the usual representatives came, he spoke to them in moderate terms and had them pass a resolution appointing him general plenipotentiary of the Greeks and undertaking themselves to join in an expedition against Persia seeking satisfaction for the offences which the Persians had committed against Greece.​ Successful in this, the king returned to Macedonia with his army.

Q. Curtius Rufus - Historiae Alexandri Magni Book I [Missing]

The Historiae Alexandri Magni by Quintus Curtius Rufus is a significant historical work detailing the life and campaigns of Alexander the Great. Originally composed of ten books, this biography provides a comprehensive narrative of Alexander's exploits. However, the loss of the first two books has left a gap in the early part of Alexander's story, which scholars and historians have sought to reconstruct through other sources and historical references.

The first book of Historiae Alexandri Magni would have provided valuable insights into Alexander's early life, including his birth, education, and the events leading up to his ascension to the throne. This period is crucial for understanding the formative influences that shaped Alexander's character and leadership style. The absence of this book means that modern scholars must rely on other ancient sources to fill in the details of his youth and the early stages of his career.

The loss of Book I of Quintus Curtius Rufus' Historiae Alexandri Magni represents a significant gap in the historical narrative of Alexander the Great. However, through careful reconstruction using other ancient sources, scholars can piece together a detailed and coherent account of Alexander's early life and rise to power. This reconstruction not only preserves the legacy of Alexander but also ensures that his formative years are not forgotten in the annals of history.

Reconstructing Book I

To bridge the gap left by the loss of Book I, historians turn to other contemporary accounts, such as:

  • Arrian's Anabasis Alexandri: This work offers detailed descriptions of Alexander's campaigns and includes some information about his early life, drawing on sources like Ptolemy and Aristobulus.
  • Plutarch's Life of Alexander: Plutarch's biography provides a comprehensive look at Alexander's life, with particular attention to his character, education, and early exploits.
  • Diodorus Siculus' Bibliotheca historica: Book 17 of this historical library offers an overview of Alexander's conquests and includes references to his early years.
  • Justin's Epitome of the Philippic History of Pompeius Trogus: This condensed version of Trogus' history provides additional context and details about Alexander's background and rise to power.

Key Elements Likely Covered in Book I

Based on the structure of similar historical works and the content of later books, the following key elements were likely covered in the lost Book I of Historiae Alexandri Magni:

  1. Birth and Lineage: Detailing Alexander's birth in 356 BCE to King Philip II of Macedon and Queen Olympias, and his royal lineage.
  2. Early Education: Describing his education under Aristotle, which would have included philosophy, science, and military strategy.
  3. Early Demonstrations of Leadership: Highlighting notable events from Alexander's youth, such as taming Bucephalus and participating in his father's military campaigns.
  4. Political Environment: Explaining the dynamics of the Macedonian court and Philip II's various marriages and alliances.
  5. Philip's Achievements: Summarizing Philip II's conquests and political maneuvers, which laid the groundwork for Alexander's future campaigns.
  6. Philip's Assassination: Detailing the circumstances of Philip II's assassination in 336 BCE and the immediate aftermath.
  7. Alexander's Ascension: Describing how Alexander secured his position as king, including his elimination of rivals and consolidation of power.

Plutarch - The Life of Alexander

Thus it was that at the age of twenty years Alexander received the kingdom, which was exposed to great jealousies, dire hatreds, and dangers on every hand. For the neighbouring tribes of Barbarians would not tolerate their servitude, and longed for their hereditary kingdoms; and as for Greece, although Philip had conquered her in the field, he had not had time enough to make her tame under his yoke, but had merely disturbed and changed the condition of affairs there, and then left them in a great surge and commotion, owing to the strangeness of the situation. The Macedonian counsellors of Alexander had fears of the crisis, and thought he should give up the Greek states altogether and use no more compulsion there, and that he should call the revolting Barbarians back to their allegiance by mild measures and try to arrest the first symptoms of their revolutions; but he himself set out from opposite principles to win security and safety for his realm by boldness and a lofty spirit, assured that, were he seen to abate his dignity even but a little, all his enemies would set upon him. Accordingly, he put a speedy stop to the disturbances and wars among the Barbarians by overrunning their territories with an army as far as to the river Danube, where he fought a great battle with Syrmus, the king of the Triballi, and defeated him; and on learning that the Thebans had revolted and that the Athenians were in sympathy with them, he immediately led his forces through the pass of Thermopylae, declaring that since Demosthenes had called him a boy while he was among the Illyrians and Triballians, and a stripling when he had reached Thessaly, he wished to show him that before the walls of Athens he was a man.

Arrived before Thebes,​ and wishing to give her still a chance to repent of what she had done, he merely demanded the surrender of Phoenix and Prothytes, and proclaimed an amnesty for those who came over to his side. But the Thebans made a counter-demand that he should surrender to them Philotas and Antipater, and made a counter-proclamation that all who wished to help in setting Greece free should range themselves with them; and so Alexander set his Macedonians to the work of war. On the part of the Thebans, then, the struggle was carried on with a spirit and valour beyond their powers, since they were arrayed against an enemy who was many times more numerous than they; but when the Macedonian garrison also, leaving the citadel of the Cadmeia, fell upon them in the rear, most of them were surrounded, and fell in the battle itself, and their city was taken, plundered, and razed to the ground. This was done, in the main, because Alexander expected that the Greeks would be terrified by so great a disaster and cower down in quiet, but apart from this, he also plumed himself on gratifying the complaints of his allies; for the Phocians and Plataeans had denounced the Thebans. So after separating out the priests, all who were guest-friends of the Macedonians, the descendants of Pindar,​ and those who had voted against the revolt, he sold the rest into slavery, and they proved to be more than thirty thousand; those who had been slain were more than six thousand.

Among the many and grievous calamities which thus possessed the city, some Thracians broke into the house of Timocleia, a woman of high repute and chastity, and while the rest were plundering her property, their leader shamefully violated her, and then asked her if she had gold or silver concealed anywhere. She admitted that she had, and after leading him by himself into the garden and showing him a well, told him that when the city was taken she had with her own hands cast in there her most valuable possessions. Then, as the Thracian was bending over and inspecting the place, she came behind him and pushed him in, cast many stones upon him, and killed him. And when the Thracians led her, with hands bound, to Alexander, she showed by her mien and gait that she was a person of great dignity and lofty spirit, so calmly and fearlessly did she follow her conductors; and when the king asked her who she was, she replied that she was a sister of Theagenes, who drew up the forces which fought Philip in behalf of the liberty of the Greeks, and fell in command at Chaeroneia. Amazed, therefore, at her reply and at what she had done, Alexander bade her depart in freedom with her children.​

Furthermore, he was reconciled with the Athenians, although they showed exceeding sorrow at the misfortunes of Thebes; for although they had begun the festival of the mysteries, they gave it up in consequence of their grief,​ and upon the Thebans who sought refuge in their city they bestowed every kindness. But notwithstanding this, whether his rage was now sated, as a lion's might be, or whether he wished to offset a deed of the most sullen savagery with one that was merci­ful, he not only remitted all his charges against the city, but even bade it give good heed to its affairs, since, if anything should happen to him, it would have the rule over Greece. In later times, moreover, as we are told, the calamity of the Thebans often gave him remorse, and made him milder towards many people. And certainly the murder of Cleitus,​ which he committed in his cups, and the cowardly refusal of his Macedonians to follow him against the Indians,​ whereby they as it were robbed his expedition and his glory of their consummation, he was wont to attribute to the vengeful wrath of Dionysus.​ And there was not a Theban of those that survived who afterwards came to him with any request and did not get what he wanted from him. Thus much concerning Thebes.

And now a general assembly of the Greeks was held at the Isthmus,​ where a vote was passed to make an expedition against Persia with Alexander, and he was proclaimed their leader. Thereupon many statesmen and philosophers came to him with their congratulations, and he expected that Diogenes of Sinope also, who was tarrying in Corinth, would do likewise. But since that philosopher took not the slightest notice of Alexander, and continued to enjoy his leisure in the suburb Craneion, Alexander went in person to see him; and he found him lying in the sun. Diogenes raised himself up a little when he saw so many persons coming towards him, and fixed his eyes upon Alexander. And when that monarch addressed him with greetings, and asked if he wanted anything, "Yes," said Diogenes, "stand a little out of my sun." It is said that Alexander was so struck by this, and admired so much the haughtiness and grandeur of the man who had nothing but scorn for him, that he said to his followers, who were laughing and jesting about the philosopher as they went away, "But verily, if I were not Alexander, I would be Diogenes."

And now, wishing to consult the god concerning the expedition against Asia, he went to Delphi; and since he chanced to come on one of the inauspicious days, when it is not lawful to deliver oracles, in the first place he sent a summons to the prophetess. And when she refused to perform her office and cited the law in her excuse, he went up himself and tried to drag her to the temple, whereupon, as if overcome by his ardour, she said: "Thou art invincible, my son!" On hearing this, Alexander said he desired no further prophecy, but had from her the oracle which he wanted.

Moreover, when he set out upon his expedition,​ it appears that there were many signs from heaven, and, among them, the image of Orpheus at Leibethra (it was made of cypress-wood) sweated profusely at about that time. Most people feared the sign, but Aristander bade Alexander be of good cheer, assured that he was to perform deeds worthy of song and story, which would cost poets and musicians much toil and sweat to celebrate.
