Alexander the Great
Alexander was born in 356 BC in Macedonia, the area surrounding present day Thessaloniki in northern Greece. Though the Macedonians might have considered themselves part of the Greek cultural world, the other Greeks might have viewed them as half-barbarians. Alexander's father, King Philip, was an energetic ruler who had started a systematic policy of expanding his kingdom. Philip's main conquest was that of the Greek mainland, after his victory at Chaeronea in 338 BC. Alexander, still in his teens, commanded the Macedonian cavalry during this battle.
In 336 BC King Philip was killed and Alexander ascended to the throne of Macedonia. Within the next twelve years Alexander conquered almost the entire known world of his era. Though Alexander made use of the well-oiled army created by his father, he pushed the limits of Macedonian & Greek power to levels King Philip could not have dreamed of.
