Tutankhamun, also spelled Tutankhamen and Tutankhamon, original name Tutankhaten, byname King Tut, (flourished 14th century bce), king of ancient Egypt (reigned 1333–23 bce), known chiefly for his intact tomb, KV 62 (tomb 62), discovered in the Valley of the Kings in 1922. During his reign, powerful advisers restored the traditional Egyptian religion and art, both of which had been set aside by his predecessor Akhenaten, who had led the “Amarna revolution.” (See Amarna style.)
