Alexander The Great in Wikipedia
Alexander III of Macedon (356–323 BC), popularly known as Alexander the Great (Greek: Μέγας Ἀλέξανδρος, Mégas Aléxandros), was a Greeki[›] king (basileus) of Macedon. He is the most celebrated member of the Argead Dynasty and created one of the largest empires in ancient history. Born in Pella in 356 BC, Alexander was tutored by the famed philosopher Aristotle, succeeded his father Philip II of Macedon to the throne in 336 BC after the King was assassinated, and died thirteen years later at the age of 32. Although both Alexander's reign and empire were short-lived, the cultural impact of his conquests lasted for centuries. Alexander was known to be undefeated in battle and is considered one of the most successful commanders of all time. He is one of the most famous figures of antiquity, and is remembered for his tactical ability, for his conquests, and for spreading Greek culture into the East, marking the beginning of Hellenistic civilization.
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. He succeeded in being awarded the generalship of Greece and, with his authority firmly established, launched the military plans for expansion left by his father. He invaded Persian-ruled Asia Minor, and began a series of campaigns lasting ten years. Alexander repeatedly defeated the Persians in battle; marched through Syria, Egypt, Mesopotamia, Persia, and Bactria; and in the process he overthrew the Persian king Darius III and conquered the entirety of the Persian Empire.ii[›] Following his desire to reach the "ends of the world and the Great Outer Sea", he invaded India, but was eventually forced to turn back by the near-mutiny of his troops.
Alexander died in Babylon in 323 BC, before 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 Macedonian aristocracy (the Diadochi). Remarkable though his conquests were, Alexander's lasting legacy was not his reign, but the cultural diffusion his conquests engendered. Alexander's importation of Greek colonists and culture to the East resulted in a new Hellenistic culture, aspects of which were still evident in the traditions of the Byzantine Empire until the mid-15th century. Alexander became legendary as a classical hero in the mold of Achilles, and features prominently in the history and myth of Greek and non-Greek cultures. He became the measure against which generals, even to this day, compare themselves, and military academies throughout the world still teach his tactical exploits.iii[›]
