What was Tutankhamun's original name?

Tutankhamun was an Egyptian pharaoh of the 18th dynasty (ruled c. 1332 – 1323 BC in the conventional chronology), during the period of Egyptian history known as the New Kingdom. He has, since the discovery of his intact tomb, been referred to colloquially as King Tut.

His original name, Tutankhaten, means "the living image of Aten", while Tutankhamun means "the living image of Amun." In hieroglyphs, the name Tutankhamun was typically written Amun-tut-ankh because of a scribal custom that placed a divine name at the beginning of a phrase to show appropriate reverence. He is possibly also the Nibhurrereya of the Amarna letters, and likely the 18th dynasty king Rathotis who, according to Manetho, an ancient historian, had reigned for nine years—a figure that conforms with Flavius Josephus's version of Manetho's Epitome.

The 1922 discovery by Howard Carter of Tutankhamun's nearly intact tomb, funded by Lord Carnarvon, received worldwide press coverage. It sparked a renewed public interest in ancient Egypt, for which Tutankhamun's mask, now in the Egyptian Museum, remains a popular symbol. In February 2010, genetic testing confirmed that he was the son of the mummy found in the tomb KV55, believed by some to be Akhenaten. His mother was his father's sister and wife, whose name is unknown but whose remains are positively identified as The Younger Lady mummy found in KV35.
