Tutankhamun or Tutankhamen (c. 1341 BC – c. 1323 BC), was an ancient Egyptian pharaoh who ruled c. 1332 – 1323 BC during the late Eighteenth Dynasty of ancient Egypt. Born Tutankhaten, he was likely a son of Akhenaten, thought to be the KV55 mummy. His mother was identified through DNA testing as The Younger Lady buried in KV35; she was a full sister of her husband.
