Crown Prince Thutmose

Crown Prince Thutmose (or, more accurately, Djehutymos) was the eldest son of pharaoh Amenhotep III, who lived during the Eighteenth dynasty of Egypt. He disappears from the public records appearing to have died some time during the third decade, fairly late, in Amenhotep III's kingship. His younger brother Amenhotep IV - better known as Akhenaten - then succeeded to the throne instead.
