Alexander III of Macedon, known as Alexander the Great (356–323 BC), became king of Greece at the age of twenty. In the course of his victory over the Persian Empire, he gradually extended the borders of his kingdom until they touched the Himalaya Mountains. After his early death, his empire was shaken by civil wars and finally split into several states.
