Alexander the Great, one of the world's greatest military commanders, was born in Pella - Macedonia in northern Greece, the son of King Philip II of Macedonia and Olympids, daughter of King Neoptolemos. Between 342 and 340 BC his tutor was the philosopher Aristotle. Alexander had already distinguished himself in battle at Chaironaia in 338 BC when he secured the throne as Alexander III by eliminating his rivals after the death of his father in 336 BC at the hands of Pausanias, possibly a hired assassin. Appointed Commander of the Corinthian League he moved first against the Thracians and the Illyrians and put down a rising by the Thebans (335 BC). As supreme commander of the Greeks in 334 BC Alexander, with his army of 35,000 men, embarked on a campaign of "Hellenistic revenge" against the Persians, crossing the Hellespont (Dardanelles), winning the battle on the Granikos in the spring, occupying Gordion (remembers the story of him cutting the legendary Gordian knot), then marching over the Taurus mountains to Cilicia and defeating Darius III, the Persian king, in November of 333 at Issus, north of present-day Iskenderun. This left the way open to Egypt where he founded the city of Alexandria and had his divine origins and claim to power confirmed by the oracle of Zeus Ammon at the Siwa oasis.
