Alexander III the Great, the King of Macedonia and conqueror of the Persian Empire is considered one of the greatest military geniuses of all times. He was inspiration for later conquerors such as Hannibal the Carthaginian, the Romans Pompey and Caesar, and Napoleon. Alexander was born in 356 BC in Pella, the ancient capital of Macedonia. He was son of Philip II, King of Macedonia, and Olympias, the princess of neighboring Epirus. Born in Pella in 356 BC, Alexander was tutored by the famed philosopher Aristotle. In 336 BC he succeeded his father Philip II of Macedon to the throne after he was assassinated. Philip had brought most of the city-states of mainland Greece under Macedonian hegemony, using both military and diplomatic means. Upon Philip’s death, Alexander inherited a strong kingdom and an experienced army. In 334 BC he invaded Persian-ruled Asia Minor and began a series of campaigns lasting ten years. Alexander broke the power of Persia in a series of decisive battles, most notably the battles of Issus and Gaugamela. Subsequently he overthrew the Persian king Darius III and conquered the entirety of the Persian Empire. The Macedonian Empire now stretched from the Adriatic sea to the Indus river. Following his desire to reach the “ends of the world and the Great Outer Sea”, he invaded India in 326 BC, but was eventually forced to turn back by the near-mutiny of his troops. Alexander died in Babylon in 323 BC, without realizing a series of planned campaigns that would have begun with an invasion of Arabia. In the years following Alexander’s death a series of civil wars tore his empire apart which resulted in the formation of a number of states ruled by the Diadochi – Alexander’s surviving generals. Although he is mostly remembered for his vast conquests, Alexander’s lasting legacy was not his reign, but the cultural diffusion his conquests engendered.
