Alexander the Great was the Macedonian king who, between 334 and 323 BCE, conquered the Persian Empire and extended Greek power from Egypt to India, creating the largest empire the ancient world had yet seen. His campaigns spread Greek culture across a vast area, inaugurating the Hellenistic age and reshaping the political geography of the ancient world for centuries.

Life and legacy

Alexander was born in 356 BCE in Pella, the capital of Macedon, to King Philip II and Olympias, a princess of Epirus. Philip had transformed Macedon from a backwater kingdom into the dominant military power of Greece, and he ensured that his son received both a warrior's training and an intellectual education: Aristotle served as Alexander's tutor from 343 to 340 BCE, reportedly kindling in him a love of Homer, science, and philosophy. Alexander is said to have slept with a copy of the Iliad - annotated by Aristotle - under his pillow throughout his campaigns.

Alexander ascended the throne at twenty after Philip's assassination in 336 BCE. After swiftly consolidating power in Greece - including the ruthless destruction of Thebes - he crossed into Asia in 334 BCE with an army of about 37,000. Over the next eleven years, he won a series of decisive battles against the Persian Empire: Granicus (334 BCE), Issus (333 BCE), and Gaugamela (331 BCE), the last of which shattered the army of Darius III and ended the Achaemenid Empire after more than two centuries. He went on to conquer Egypt (where he founded Alexandria), Central Asia, and parts of northwestern India, before his army refused to march further at the Hyphasis River in 326 BCE.

Alexander's military genius is undisputed. He adapted his tactics brilliantly to different opponents and terrain, used combined arms (cavalry, infantry, siege craft) with unprecedented sophistication, and led from the front with extraordinary personal courage - he was wounded seriously at least four times. His ability to inspire loyalty in an army that marched over 20,000 miles in a decade was remarkable. But his campaigns also involved acts of devastating violence, including the massacre of the population of Tyre and the burning of Persepolis.

The cultural consequences of Alexander's conquests were immense. His policy of founding cities - some seventy, according to Plutarch, though the number is debated - planted Greek-speaking communities across western and central Asia. Alexandria in Egypt became the intellectual capital of the Mediterranean world. The Hellenistic civilization that emerged from his conquests blended Greek, Persian, Egyptian, and Indian elements and lasted until the Roman conquests. Greek became the lingua franca of the eastern Mediterranean, which is why the New Testament was later written in Greek and why Hellenistic philosophy (Stoicism, Epicureanism, Skepticism) could spread across such a vast cultural area.

Alexander died in Babylon on June 10 or 11, 323 BCE, at the age of thirty-two. The cause of death - fever after a prolonged drinking bout - has been debated for centuries; theories range from typhoid fever to poisoning to the cumulative effects of his many wounds. His empire fragmented immediately among his generals (the Diadochi), who carved it into the Ptolemaic, Seleucid, and Antigonid kingdoms. Alexander's legend, however, only grew: he became a hero in Greek, Roman, Persian, Arabic, and medieval European literature, and his name (Iskander, Sikandar) is known across Eurasia.
