King Alexander, often referred to as Alexander the Great, was a king of the ancient Greek kingdom of Macedonia. He was born in 356 BC and became known for his extraordinary military conquests. By the age of 30, he had created one of the largest empires in history, stretching from Greece to Egypt and into parts of India. Alexander was a student of the philosopher Aristotle, who influenced his thinking and leadership style. His tactics in battle are still studied today, and he is remembered for spreading Greek culture throughout his empire, a period known as the Hellenistic Era.
