Tutankhamen, (TOOT-ahnk-AH-men) sometimes called King Tut for short, was called the boy king of Egypt. He was born to Pharaoh Akhenaten (AH-ken-AH-ten) and his minor wife Queen Kiya. When Akhenaten died, Tut, age 9, married Ankhesenamen (AHNK-eh-sen-ah-MEN) his half sister. One theory about Tutankhamen's death is that the vizier, a man named Aye (EYE), killed King Tut. When he was 19 or 20, King Tut mysteriously died from a blow to the head, and Aye became the next pharaoh.
