Aristotle was Alexander’s personal tutor, which Philip had hired. During the next three years Aristotle gave Alexander training in rhetoric and literature, and also made him interested in science, medicine, and philosophy. When Alexander was 16, in 340, his father assembled a large Macedonian army and invaded Thrace. As Philip continued to go deeper into Thrace, he left Alexander power over Macedonia, which shows that even at a young age, Alexander was trustworthy and recognized as capable of ruling. But as the Macedonian army got further and further from Macedonia the Thracian tribe bordering north-eastern Macedonia rebelled and posed a danger to the country. So Alexander assembled an army, led it against the enemy and defeated them easily, he captured their stronghold and renamed it after himself to Alexandropolis. After 338 B.C. he took his mother a fled the country to Epirus, because of argument with his father and the general Attalus. He was allowed to return later, he remained isolated and insecure at the Macedonian court.

In 336 B.C, with Philips Persian invasion already set in motion, the king was assassinated by a Macedonian noble Pausanias, during the wedding ceremony. Now that Philip, the great Macedonian conqueror was dead, the power lies in Alexander’s hands, and Philips goal of conquering the Persian Empire is up King Alexander III to continue. After Alexander became king he quickly got rid of his domestic enemies by ordering their execution. But now he had to act outside of Macedonia. After Philips death there was a series of rebellions among the conquered nations, because they thought their new ruler wasn’t as wise. By 30 years old Alexander the Great had conquered the most of the known world. Even though he conquered the nations he gained loyalty and respect from the people in the nation, because he wasn’t harsh on the people, he let them run their own religion and freed them from slavery. After conquering enough nations his goal of conquering and punishing the Persian Empire was forgotten, now his goal was to conquer the known world.

He changed his mind about his goals because he had so much power the problem with Persians didn’t bother him any more. He got sick most likely of malaria, and died on 323 B.C, at age 33. He was buried in Alexandria in Egypt. Alexander never designated the next leader for the Macedonian Empire. Because he never designated any one to rule, it created conflicts, commanders fought each other for power. If they resolved the problem of who’ll be the leader peacefully and they could have still been a strong nation. After the Greeks heard of Alexander’s death they rebelled again and begun the Lamian War. The Macedonians were defeated and expelled from Greece, but then Antipater received reinforcements from Craterus who brought to Macedonia the 10,000 veterans discharged at Opis.  Antipater and Craterus jointly marched into Greece, defeated the Greek army at Crannon in Thessaly and brought the war to an end.
