Alexander III of Macedon, remembered as Alexander the Great, was born in 356 BCE, the son of King Philip II of Macedon, a kingdom on the northern edge of the Greek world. As a boy he was tutored by the philosopher Aristotle, who taught him literature, science, and philosophy and gave him a lifelong love of Greek culture, especially the poems of Homer. His father, meanwhile, built Macedon into a military powerhouse with a professional army and a fearsome infantry formation called the phalanx. When Philip was assassinated in 336 BCE, the 20-year-old Alexander inherited both a battle-ready army and his father's plan to invade the mighty Persian Empire. What followed is one of the most astonishing military careers in history. In just about 13 years, Alexander led his army from Greece across Asia, defeating the vast Persian Empire in a series of brilliant battles at the Granicus, Issus, and Gaugamela, where he repeatedly beat much larger forces through daring tactics and bold cavalry charges he often led in person. He conquered Egypt, toppled the Persian king Darius III, and pushed all the way to the edge of India. In doing so he avenged and reversed the old Greek-Persian wars of a century earlier, whose turning points included the Battle of Marathon. By the time he stopped, he had built one of the largest empires the ancient world had ever seen, stretching from Greece and Egypt to the borders of India, and by tradition he never lost a battle. Alexander did more than conquer; he reshaped the ancient world. He founded some twenty new cities, the most famous being Alexandria in Egypt, which grew into a legendary center of learning and trade. His conquests spread the Greek language, art, and ideas across three continents, mixing them with Egyptian, Persian, and Indian cultures to create a rich new blend historians call the Hellenistic era. For centuries afterward, Greek became a common language of scholarship and commerce across the eastern Mediterranean and Near East, a lasting legacy far larger than his empire itself. Alexander's story is not simply one of glory, and students should weigh it honestly. His campaigns were extraordinarily violent, sometimes destroying whole cities such as Thebes and Tyre, and his ambition seemed to have no limit. He could be generous to those who submitted and brutal to those who resisted, and in his later years he grew increasingly grandiose, even demanding to be treated as a god. He died suddenly in 323 BCE at just 32, probably of fever or illness, leaving no clear heir. Almost immediately his generals tore the empire apart in decades of war. Alexander left behind a world permanently changed by the spread of Greek civilization, and an enduring debate about whether greatness measured in conquest is truly greatness at all.
