Drought Led to Collapse of Civilizations, Study Says

What happened about 3,200 years ago to bring about the collapse of not just one but a number of flourishing civilizations on the eastern shores of the Mediterranean?

Wars, pestilence, and sudden natural disasters have all been postulated as possible causes, but now, thanks to sophisticated pollen-sampling techniques and advances in radiocarbon dating, Finkelstein and his colleagues believe they know the primary culprit: drought, or rather a succession of severe droughts over a 150-year period from 1250 BCE to about 1100 BCE.
