Alexander the Great (Ancient Pella, July 356 BC – Babylon, June 10, 323 BC), commonly known as Alexander the Great or Alexander III of Macedon, was a Greek king of the Kingdom of Macedonia, emperor of Macedonia (after his campaign) and member of the Argead dynasty. He was the ruler of the Panhellenic Alliance against the Achaemenid Empire. The conquests were the cornerstone of the Hellenistic era of the kingdoms of his Successors and Descendants. He was one of the most important generals in history, and during the 13 years of his reign (336 – 323 BC) he conquered most of the then known world to the east (Asia Minor, Persia, Egypt, etc.), reaching on the outskirts of India, and without having been defeated in a battle in which he himself took part. He died in Babylon, in the palace of Nebuchadnezzar II on June 10, 323 BC, at the age of 32. All of his influence often ranks him among the world’s leading figures of all time with the greatest influence, along with his teacher Aristotle.
