The Secrets to Civilization S01E02 - Cities and Empires

Historians and archaeologists worked long on various theories about the extinction of most Mediterranean states and cultures around the reign of Pharaon Rameses III (+1155 BC), except his own Egypt, from the Myceneans to the Hittites and Babylonians. The few Ancienr records, mainly his, confirm a dark age of famine and invasions form unidentified 'sea people'. Yet none of the advanced disasters and wars accounts for the synchronicity. Then climatic records made it all fit, as drought resulting from temperature drop explain all storms and famine-driven migrations while sedentary states and commerce collapses in a chain, only the fertile Nile banks remaining a prosperous sanctuary for the superpower to remain standing.
