Alexander the Great
✨ 356–323 BCE, King of Macedonia and conqueror
Alexander the Great was born in 356 BCE in Pella, the capital of the ancient kingdom of Macedon. Son of King Philip II and Olympias, he became king in 336 BCE at the age of twenty. He had been educated by Aristotle, who taught him literature, philosophy, science, and politics. Soon after taking the throne, Alexander secured his authority in Greece and began the campaign against the Persian Empire that his father had prepared.
In 334 BCE, he crossed into Asia Minor and defeated Persian forces at the Granicus River. He then won major battles at Issus in 333 BCE and Gaugamela in 331 BCE, opening the way to the Persian heartland. He captured Babylon, Susa, and Persepolis and eventually became ruler of the vast Persian Empire. Alexander continued eastward through Central Asia and reached the Indian subcontinent in 326 BCE.
At the Hydaspes River, he defeated the army of King Porus, but his troops eventually refused to advance farther east. Alexander began the return journey and reached Babylon in 323 BCE, where he died at the age of thirty-two. The exact cause of his death remains uncertain. He left no clearly established adult successor, and his empire was soon divided among his generals, known as the Diadochi.
Although his political empire did not remain united, his campaigns greatly increased contact between Greek and Near Eastern societies. Greek language and culture spread across many regions, while local traditions continued to influence the new Hellenistic societies that developed after his death.
