Alexander the Great

Alexander the Great (Greek: Ἀλέξανδρος ὁ Μέγας or Μέγας Ἀλέξανδρος,[1] Mégas Aléxandros; 356 BC – 323 BC),[2] also known as Alexander III of Macedon (Ἀλέξανδρος Γ’ ὁ Μακεδών) was an ancient Greek[3] King (basileus) of Macedon (336–323 BC). He was one of the most successful military commanders of all time and is presumed undefeated in battle. By the time of his death, he had conquered (see Wars of Alexander the Great) the Achaemenid Persian Empire, adding it to Macedon’s European territories; according to some modern writers, this was most of the world as known to the ancient Greeks.[4][5][n 1]
