Alexander the great - National Geographic Documentary

Alexander III of Macedon, better known as Alexander the Great, single-handedly changed the nature of the ancient world in little more than a decade. Alexander was born in Pella, the ancient capital of Macedonia in July 356 BC.

His parents were Philip II of Macedon and his wife Olympias. Alexander was educated by the philosopher Aristotle. Philip was assassinated in 336 BC and Alexander inherited a powerful yet volatile kingdom. He quickly dealt with his enemies at home and reasserted Macedonian power within Greece. He then set out to conquer the massive Persian Empire. Against overwhelming odds, he led his army to victories across the Persian territories of Asia Minor, Syria and Egypt without suffering a single defeat.

His greatest victory was at the Battle of Gaugamela, in what is now northern Iraq, in 331 BC. The young king of Macedonia, leader of the Greeks, overlord of Asia Minor and pharaoh of Egypt became 'great king' of Persia at the age of 25.
