Alexander the Great was the king of the ancient Greek kingdom of Macedonia and one of the world's greatest military generals. When Alexander was 20, his father King Phillip was assassinated. Then the nobles and the army made him King. Although he ruled for less than 13 years, he made massive changes to history, by creating the largest empire the ancient world had ever seen, from Greece to Egypt and to parts of India. This allowed Greek culture to become well known in the majority of the ancient world. In his years as King, he never lost a battle, but he was “defeated” by death in Babylon, due to sickness, at 32 years old.
