Alexander III of Macedon (20/21 July 356 – 10/11 June 323 BC) is commonly known as Alexander the Great, was a Greek king of Macedon, a state in northern ancient Greece. Born in Pella in 356 BC, Alexander was tutored by Aristotle until the age of 16. By the age of thirty, he had created one of the largest empires of the ancient world, stretching from the Ionian Sea to the Himalayas. He was undefeated in battle and is considered one of history's most successful commanders. On either 10 or 11 June 323 BC, Alexander died in the palace of Nebuchadnezzar II, in Babylon, at age 32. There are two different versions of Alexander’s death and details of the death differ slightly in each, the first that he developed a fever and in the second account, he was struck with pain after downing a large bowl of unmixed wine in honor of Hercules.
