As the forceful king of Macedonia(马其顿), Alexander the Great overthrew the Persian Empire, becoming a hero that would survive centuries after his death.

Born in 356 B.C., Alexander III was the son of Philip II and Olympias. Alexander’s parents wanted him to receive the finest education, and arranged for him to study under Aristotle, regarded as one of the greatest scholars.

Alexander’s father was a strong leader. Philip II built an impressive army and established the Macedonian kingdom; he was even planning to attack Persia shortly before his death.

In 336, Philip was murdered by one of his guards. Although it was obvious that the guard had a personal hatred, there are clues that other people were related to it.

After Alexander was cleared as a suspect, he succeeded his father without opposition, and killed those said to be responsible for his father’s murder, as well as all rivals. He was then just 20 years old. He then prepared to attack Persia.

In the spring of 334, Alexander led the army made up of nearly 50,000 soldiers into Asia, which is called “the most powerful military expedition ever to leave Greece”, He soundly defeated the Persian army at the Granicus River, sending a strong message to Darius III, leader of the Persian Empire.

In 333, Alexander faced Darius at Issus, a mountain pass. The Macedonian army was greatly outnumbered but able to work the narrow mountain passageway to their advantage. Darius managed to escape. Continuing down the Mediterranean Coast, Alexander took every city in his path.

In 332 Alexander declared Egypt to be part of the Greek Empire and was crowned Pharaoh(法老).

When Alexander left Egypt in 331, he defeated the Persians again and was crowned leader of Asia.

In 323, however, Alexander developed a fever on the way back home and died 10 days later at Babylon. He was just 33 years old.
