00:00In the long history of mankind, countless kings have ruled the world,
00:04great armies have marched across continents, and mighty empires have risen, only to fall
00:09into dust. But among them all, one name stands above the rest. A man who conquered nearly the
00:17entire known world. Before the age of 30, a commander who never lost a single battle,
00:23a king who turned a small kingdom into the greatest empire the ancient world had ever
00:28seen. His name was Alexander the Great. From the mountains of Macedonia, to the deserts
00:35of Egypt, from the magnificent capitals of the Persian Empire, to the distant borders
00:40of India, Alexander and his army marched farther than any army before them. But how did a young
00:47prince become the greatest general in history? How did one man change the fate of the ancient
00:52world forever? This is the story of Alexander the Great.
00:59In the year 356 BC, in a city called Pella, the capital of the ancient kingdom of Macedon,
01:05a child was born who would go on to change the course of human history more dramatically,
01:10more completely, and more permanently than almost any other individual who has ever drawn
01:14breath on this earth. The world into which he was born was a world of city-states and kingdoms,
01:19of rival powers and ancient grudges, of gods worshipped on mountain peaks and oracles consulted
01:25in smoky temples. It was a world that believed in destiny, in divine favor, in the idea that
01:31certain men were marked from birth for something beyond the ordinary, and if that belief was ever
01:35justified. If that ancient intuition about greatness written into certain souls before
01:40they even take their first breath was ever proven correct. It was proven correct on the night that
01:45Alexander entered the world. His mother Olympias, a fierce and deeply spiritual woman from the kingdom
01:50of Epirus, believed with absolute conviction that her son was no ordinary child. She had dreamed of
01:55lightning striking her womb before his birth. She told the boy, from the time he was old enough
02:00to understand words, that his true father was not the king of Macedon, but Zeus himself, the lord of
02:07the gods, the ruler of the heavens. Whether Alexander believed this literally or understood, it is the
02:13kind of mythological framing that the ancient world used to describe extraordinary people.
02:17It shaped him, it gave him a sense of mission that went beyond political ambition,
02:21beyond the ordinary hunger for power that drives most rulers. He did not merely want to win.
02:27He wanted to be remembered forever. He wanted to stand alongside the heroes of the
02:32stories he loved, the great warriors and demigods whose names had echoed through centuries.
02:37He wanted eternity. And in the end, with a breathtaking completeness that even he might not have fully
02:43imagined in his most ambitious dreams, he got it. His father, Philip II of Macedon, was himself a
02:50remarkable man, and it would be a serious mistake to understand Alexander without first understanding
02:55Philip. The Macedon that Philip inherited was not the Macedon he built. When Philip came to power,
03:02Macedon was a relatively minor kingdom on the northern edges of the Greek world, looked down upon by the
03:07sophisticated city-states of Athens and Thebes and Corinth as a semi-barbaric backwater, a land of rough
03:13mountain, people who spoke a dialect of Greek that Southerners could barely understand. Philip changed
03:18everything. He was a military genius, a diplomatic mastermind, and a relentless builder of institutions.
03:24He reorganized the Macedonian army from top to bottom, creating what became one of the most lethal and
03:30innovative military machines the ancient world had ever seen. The centerpiece of his military
03:36reform was the Macedonian phalanx, a formation of infantry soldiers armed with an enormously long
03:42spear called the sarissa, which could be up to 21 feet in length. When a Macedonian phalanx locked into
03:48formation, the soldiers in the front ranks held their sarissas horizontally, pointing forward, while the
03:53soldiers in the ranks behind angled their weapons upward at progressively steeper angles, creating a
03:59bristling wall of overlapping spear points that was nearly impossible for enemy infantry to break
04:03through from the front. But Philip did not stop with the infantry. He built a superb cavalry arm, an elite
04:09force of horsemen called the Companion Cavalry, and he developed sophisticated siege warfare techniques
04:14that allowed him to take fortified cities that would have stopped earlier Macedonian armies cold.
04:19He also understood something that many military leaders forget, that the best army in the world is
04:24worthless without the economic base to sustain it and the diplomatic skill to isolate enemies
04:29before destroying them. Philip was as gifted a diplomat as he was a soldier. He bribed, he married
04:36strategically, he made alliances and then discarded them when they were no longer useful, he divided his
04:41enemies and picked them off one by one. By the time Alexander was born, Philip had already transformed
04:46Macedon from a marginal kingdom into the dominant power in the Greek world. He was building something
04:52extraordinary, and he knew that the son who would inherit what he was building, needed to be
04:56extraordinary too. Alexander did not disappoint. From his earliest years the boy showed qualities that set
05:03him apart in ways that were obvious even to those who had reason to underestimate him. He was physically
05:08remarkable, compact, and powerful, with a slightly tilted neck that became one of his most recognizable
05:14features. One eye reportedly dark, and one lighter. A face that ancient accounts describe as strikingly
05:21beautiful, with an almost luminous quality. But his physical presence was secondary to what burned
05:26inside him. He was possessed by an ambition that was not the ordinary ambition of a boy who
05:32wants to be important or respected or wealthy. It was something closer to a religious conviction,
05:37a certainty that he was meant for something beyond what any ordinary framework of achievement could
05:42contain. He was not interested in being a successful king of a successful kingdom.
05:46He was interested in being Alexander. And being Alexander meant doing something that had never
05:51been done before. The story of the horse Bucephalus, which ancient sources tell with obvious delight
05:58captures something essential about who Alexander was even as a child. The horse had been brought to
06:03Philip's court as a potential acquisition. A magnificent animal, large and powerful and clearly of
06:08exceptional quality. But when Philip's men tried to handle it, the horse went wild. No one could
06:14control it. No. One could even get close to it without the animal becoming dangerously agitated.
06:21Philip watched the attempts with growing frustration and finally declared the horse useless and ordered
06:26it taken away. It was at this moment that the twelve-year-old Alexander spoke up. He had been watching
06:32the horse carefully while the adults struggled with it, and he had noticed something they had all missed.
06:36The horse was terrified of its own shadow. Every time someone approached it, and it began to move,
06:42its shadow moved. With it. And the sight of this dark shape shifting beneath its feet sent the animal
06:47into panic. Alexander asked his father for permission to try. Philip, according to the ancient accounts,
06:53laughed and made a bet with his son. If Alexander could tame the horse, he could keep it. If he
06:58could
06:58not, he would pay the price of the animal himself. Alexander walked up to the horse, took it by the
07:03bridle,
07:03and turned it to face directly into the sun. With the horse facing the light, the shadow fell behind
07:08it where it could not see it. The animal calmed. Alexander stroked it, spoke to it, and then mounted
07:14it and rode it across the field. When he returned, the court erupted, and Philip reportedly wept.
07:23Not from sadness, but from a mixture of pride and something that bordered on awe. He said to his son,
07:29and these words have echoed across 24 centuries, My son, seek a kingdom equal to yourself.
07:36Macedonia is too small for you. Philip understood in that moment that what he had fathered was
07:41something that would outgrow every container anyone tried to put around it. When Alexander was 13 years
07:47old, Philip made a decision about his son's education that reveals just how seriously he
07:52took the boy's potential. He hired Aristotle. Not some local tutor, not a competent but
07:58undistinguished teacher, but the man who was already recognized as one of the greatest minds in the
08:03Greek world, a student of Plato, who would go on to shape the intellectual foundations of Western
08:08civilization in fields ranging from logic and ethics to biology and politics. Philip offered
08:13Aristotle exceptional terms including the rebuilding of Aristotle's home city of Stagira, which had been
08:18destroyed by Macedonian military action. And Aristotle accepted. For the next three years,
08:24Alexander studied under Aristotle, at a place called Miesa, a kind of outdoor school set and gardens.
08:29What they discussed, what they argued about, how Aristotle shaped the mind of the boy who would
08:34become the conqueror of the known world. These are questions that historians have debated for
08:39centuries. We know that Alexander received a comprehensive education. He studied philosophy,
08:45the systematic examination of how the world works, and how human beings should live in it.
08:49He studied science. And Aristotle's encyclopedic curiosity about the natural world clearly left a
08:54mark on Alexander, who throughout his military campaigns showed an unusual interest in the flora and
08:59fauna and geological features of the places. He passed through, sending specimens and observations back to
09:05his teacher. He studied medicine at a level that was remarkably practical. Ancient accounts say Alexander
09:10was not only capable of diagnosing illnesses but actively participated in treating wounded soldiers,
09:15not just issuing orders but getting his hands involved in the actual work of healing.
09:20He studied literature with a passion that never left him. And above all the other texts, above all the stories
09:26and poems and philosophical dialogues that Aristotle placed before him, Alexander loved the Iliad.
09:31The Iliad was not merely a poem to Alexander. It was a template, a mirror, a statement of what
09:38human existence was for. The story of Achilles, the greatest warrior of the Trojan War, a man who had
09:46been given the choice between a long, quiet life and a short life of blazing glory, and who had chosen
09:51glory without hesitation, spoke to something at the absolute core of Alexander's identity. He identified with
09:58Achilles the way that later conquerors and leaders would identify with Alexander himself. He carried a
10:04personally, annotated copy of the Iliad everywhere he went, reportedly keeping it with a dagger under
10:09his pillow at night. When he first set foot on Asian soil at the very beginning of his great campaign,
10:15one of his first acts was to visit the ancient site believed to be Troy, where he honored the tomb
10:20of
10:20Achilles, ran races around it, anointed the gravestone with oil, and declared Achilles lucky for having a
10:26friend like Patroclus to mourn him, and a poet like Homer to celebrate his deeds. It was not a casual
10:31gesture, it was a statement of purpose. Alexander was telling himself and the world that he understood
10:36the stakes, that he intended to live at the level of the great heroes, that his story would be worthy
10:41of a Homer. Philip's extraordinary work in building Macedon reached its culmination, in 338 BC at the
10:48Battle of Charinia, where the Macedonian army faced a coalition of Greek city-states including Athens
10:53and Thebes. The Theban contribution to this coalition was particularly formidable. The Sacred Band of Thebes,
10:59an elite fighting force of 150 pairs of male lovers, based on the belief that men would fight more
11:05bravely and die rather than show cowardice in front of their beloved partners. The Sacred Band had
11:11never been defeated. At Charinia the 18-year-old Alexander commanded the companion cavalry on the
11:16left wing of the Macedonian army. When the moment came, when the gap in the enemy line appeared that
11:21Philip had maneuvered to create through feigned retreat, Alexander drove the companion cavalry through
11:26that gap, with the kind of explosive decisive violence that would become, his military signature.
11:31The Sacred Band was encircled and destroyed almost to the last man, they died where they stood,
11:37refusing to surrender, and Philip reportedly wept when he walked through their dead and understood
11:42what manner of men he had defeated. Charinia broke Greek resistance. Philip was now the undisputed
11:48master of the Greek world. He formed the League of Corinth, a political structure that united the
11:54Greek city-states under Macedonian leadership, and began planning the campaign he had dreamed of for
11:58years. An invasion of the Persian Empire, the dominant superpower of the ancient world. But Philip
12:05would never lead that invasion. In 336 BC, at the wedding of his daughter, Philip II of Macedon was
12:11assassinated. He was stabbed by one of his own bodyguards. The reasons behind the assassination have
12:17been debated ever since. Some ancient sources hint at a conspiracy involving Olympias, Alexander's mother.
12:23Others suggest purely personal grievances. What is certain is that the assassination changed everything.
12:30The throne of Macedon passed to the 20-year-old Alexander. The transition was not smooth. Kingdoms
12:36rarely survived the sudden death of a powerful king, especially when the heir was young and unproven in
12:41the eyes of the wider world. The Greek city-states that Philip had forced into submission saw their
12:48opportunity and began to move toward revolt. Rival claimants to the Macedonian throne emerged.
12:54Barbarian tribes on the northern borders stirred. The world was watching to see if this young man had
13:00what it took to hold together what his father had built. Alexander's response was one of the most
13:04impressive demonstrations of decisive action in the entire history of military leadership.
13:09He moved with a speed that left his enemies no time to coordinate. Potential rivals within Macedonia
13:14were eliminated. Then barely giving anyone time to catch their breath, he launched a campaign north
13:19against the Thracian and Illyrian tribes that threatened the Macedonian borders, crushing them
13:24in rapid succession, with exactly the combination of aggressive, cavalry action and tactical flexibility
13:29that would characterize all his greatest battles. And then when word reached him that the city of
13:34Thebes had revolted and that Athens was debating whether to join the rebellion, Alexander turned south
13:39and covered the distance to Thebes in what ancient sources describe as a matter of days.
13:43A march of such speed that the Thebans simply could not believe the army they saw outside their walls
13:48was actually Macedonian until it was too late. Thebes was taken. And then, in a decision that was as
13:55politically calculated as it was brutal, Alexander ordered the city destroyed. The houses were torn down,
14:01the population sold into slavery. The great city that had once been the dominant military power in
14:06Greece, reduced to rubble. He spared only the temples and the house of the ancient poet Pindar,
14:11whose work he revered. The message to the rest of Greece was unmistakable and perfectly clear.
14:17This was not Philip's son playing at being king. This was something different. This was Alexander.
14:23With Greece secured, with the northern borders pacified, with the domestic, threats eliminated,
14:29Alexander turned his attention to the purpose that had animated him since childhood, the Persian Empire.
14:34The empire that stretched from the Aegean coast of Asia Minor all the way east to the borders of India,
14:39from the plains of Egypt in the south to the steppes north of the Black Sea. An empire of perhaps
14:4450
14:45million people, governed from great palace cities at Susa and Persepolis in Babylon. Persia was the
14:51superpower of the ancient world. It was also, in the Greek cultural imagination, the eternal enemy.
14:57The Persians had invaded Greece twice in living memory, had burned the Acropolis of Athens during the
15:03Second Invasion, had left scars on the Greek psyche that had never fully healed. The campaign of revenge
15:09and conquest that Philip had planned, that Alexander now inherited, was framed by Alexander not merely as
15:15military expansion, but as the fulfillment of a sacred obligation, a pan-Hellenic mission of
15:21retribution and liberation. In the spring of 334 BC, Alexander crossed the Hellespont, the narrow
15:29strait of water that separates Europe from Asia, with an army of roughly 37,000 men. The crossing was
15:35itself a carefully staged piece of theatre. Alexander personally steered the lead ship across.
15:40Midway across he sacrificed a bull to Poseidon and poured a libation from a golden cup into the sea,
15:46claiming the waters as his domain. When his ship's prow touched the Asian shore he flung his
15:51spear into the earth, claiming Asia as spear-won territory. Claimed by right of conquest, he was
15:56the first off the ship. He stood on Asian soil in full armor, and declared it his. Then, he went
16:03to
16:03Troy. The visit to Troy was not a detour or a distraction. It was essential to everything that
16:09followed. Alexander understood the power of myth and symbol in a way that very few conquerors have
16:14ever matched. He understood that what people believed about who you were mattered as much as what you
16:20actually did, sometimes more. By visiting Troy, by honoring Achilles, by placing himself explicitly
16:25in the lineage of the Homeric heroes, he was telling a story about himself that would travel
16:30ahead of his army, that would reach the ears of people who had never seen a Macedonian
16:34soldier, and would shape how they understood what was coming. He was not an ordinary conqueror
16:39coming to take their lands and their wealth. He was something out of legend, a hero-king, a man whose
16:45story was already part of the great tapestry of myth that the entire Mediterranean world shared.
16:51The first major test of the invasion came quickly. The Persian satraps, the regional governors who
16:57administered Asia Minor on behalf of the Persian king, had assembled an army at the Granicus river
17:01to block Alexander's advance. The Granicus was not a trivial obstacle. It was a river with steep banks
17:08and the Persian forces were positioned on the far bank in a strong defensive position. Many of
17:13Alexander's senior commanders, including his second-in-command Parmenion, urged caution.
17:18Attack in the morning, they said. The conditions are not right, Alexander refused. He saw that the
17:24enemy expected him to hesitate. That hesitation would give them time to reinforce and would cost
17:29him the psychological advantage that came with moving immediately and aggressively.
17:33He led the companion cavalry directly into the Yar river, into the water and up the steep bank,
17:38into the concentrated fire of the Persian defenders. It was almost suicidal.
17:42Ancient accounts describe the attack as chaotic and desperate in its early moments,
17:47with Macedonian horsemen struggling up the bank and being cut down, with Alexander himself surrounded
17:52and nearly killed. Two Persian commanders struck at him, simultaneously with their cavalry lances.
17:58One blow broke his lance, another struck his helmet hard enough to cut through it and wound his scalp.
18:04A third Persian was raising his sword to finish Alexander when one of his officers killed the attacker.
18:09From behind, it was that close. But the attack succeeded. The Macedonian cavalry got up the bank
18:16in sufficient numbers and began to push the Persian cavalry back. The phalanx crossed behind them.
18:21The Persian line collapsed. In the aftermath, Alexander visited. Every wounded Macedonian soldier
18:27personally listened to their accounts of what they had experienced and made sure they knew that he had
18:32seen their courage. He shipped the captured Persian armor back to Athens as a gift, with an inscription that
18:37read, Alexander son of Philip and the Greeks accept the Lacedaemonians from the barbarians in Asia.
18:43It was propaganda of brilliant precision. It positioned the victory as a collective Greek
18:49achievement. It reminded every...
