A short time of monotheism (Atenism) happened when Akhenaten (Amenhotep IV) was pharaoh. He focused the religion on the Egyptian sun god Aten. The Aten is usually shown as a sun disk with rays coming out of all sides. Akhenaten built a new capital at Amarna with temples for The Aten. Akhenaten's religion only lasted until his death. The old religion was quickly restored by Tutankhamun, Akhenaten's son by his wife Kiya.
