Is Climate Change responsible for the downfall of the Pyramid Age of Egypt Recent palaeoenvironmental evidence suggests that northeast Africa and southwest Asia were struck by an intense 'mega-drought' around the year 2200 BC. The event has already been blamed for the collapse of complex societies in Mesopotamia and the Indus Valley. I am trying to radiocarbon date both the drought event, at the headwaters of the Nile, and the collapse of the Pyramid Age of Egypt. Ultimately, I am hoping to determine whether Climate Change may have been responsible for the downfall of the state.
