Der Untergang des alten Ägypten

Does the pyramid of Pharaoh Pepi II shed light on the reasons for the collapse of the ancient kingdom of Egypt some 4,200 years ago? Hieroglyphs in his burial chamber tell of unrest, conflagration, and devastation. Further finds point to a decline in the pharaohs' power in favor of princes and high-ranking state officials. Was the downfall not only due to political factors, but also to economic and environmental ones?
