Alexander the Great

Alexander the Great (Greek: Αλέξανδρος ο Μέγας or Μέγας Aλέξανδρος,^[1] Megas Alexandros; July 20 356 BC – June 10 323 BC),^[2][3] also known as Alexander III of Macedon (Greek: Αλέξανδρος Γ' ο Μακεδών) was an ancient Greek^[4][5] king (basileus) of Macedon (336–323 BC). He was one of the most successful military commanders in history, and was undefeated in battle. By the time of his death, he had conquered most of the world known to the ancient Greeks.
Alexander assumed the kingship of Macedon following the death of his father Philip II of Macedon. Philip had unified^[6] most of the city-states of mainland Greece under Macedonian hegemony in a federation called the League of Corinth.^[7] After reconfirming Macedonian rule by quashing a rebellion of southern Greek city-states, and staging a short but bloody excursion against Macedon's northern neighbors, Alexander set out east against the Achaemenid Persian Empire, which he defeated and overthrew. His conquests including Anatolia, Syria, Phoenicia, Judea, Gaza, Egypt, Bactria, and Mesopotamia, and extended the boundaries of his own empire as far as Punjab, India.
