Alexander the Great's Conquests: What Happened

Between 334 and 323 BC, Alexander III of Macedon, known as Alexander the Great, led an army from Greece across the Persian Empire and into India, creating one of the largest empires in history. Crossing into Asia Minor with around 40,000 men, he won major victories over the Persians at the Granicus River, Issus and Gaugamela. He took the island city of Tyre after a long siege, was welcomed in Egypt, where he founded Alexandria, and captured the great Persian capitals of Babylon, Susa and Persepolis. After the death of the Persian king Darius III, Alexander claimed his throne and pushed east through Central Asia, marrying the Bactrian princess Roxana. In 326 BC, he defeated King Porus at the Hydaspes River in India, but his exhausted soldiers refused to march farther. After a brutal return journey, Alexander died in Babylon in 323 BC, aged just 32. He never lost a major battle. His conquests spread the Greek language and culture from Egypt to Afghanistan, beginning the Hellenistic Age, and his generals divided his empire among themselves.
