Aten vs. the Egyptian Pantheon
Case description: The gods of Egypt accused Aten of deporting them from the Underworld. When Akhenaten declared Aten the Number One Deity of Egypt, the other gods got booted out. Their worshipers deserted them and their temples were abandoned. Hit the bricks, kids!
Case status: Dismissed. Aten was kicked out when Tutankhamun came to power. Touche!
