King Tutankhamun ruled Egypt as pharaoh for 10 years until his death at age 19, around 1324 B.C. Although his rule was notable for reversing the tumultuous religious reforms of his father, Pharaoh Akhenaten, Tutankhamun’s legacy was largely negated by his successors
After a few years on the throne the young king changed his religion, abandoned the Aten, and started to worship the god Amun [who was revered as king of the gods]. This caused him to change his name to Tutankhamun, or “living image of Amun”
