Alexander The Great was born in Pella, Macedonia to parents King Philip II and Queen Olympia. Tutored by Aristotle, the prince took charge of the Companion Cavalry at age 18 and aided Philip in defeating the Athenian and Theban armies at Chaeronea.
After the death of his father, Alexander garnered the support of the Macedonian Army and eliminated his enemies to become king and leader of the Corinthian League. Alexander went on to conquer Persia and Egypt, his kingdom ranging from the Mediterranean to the border of India.
Alexander’s defeat of the Persian Empire removed the block that had prevented the spread of Greek settlements into the East.
Alexander’s military genius is undisputed. He improved the fine army inherited from his father, Philip, by the addition of allied forces; he strengthened the cavalry arm, utilized weapons specialists, and employed a corps of engineers. His movements were also marked by speed.
The exact cause of Alexander's death is unknown. Historians have debated the issue for centuries, attributing it to poison, malaria, typhoid fever or other maladies. What is agreed upon is that the Macedonian king died in early June 323 BC while suffering a high fever that had lasted ten days. Alexander left his empire to no one, so it was divided between his closest 3 generals.
