Ellenblum Ronnie. The Collapse of the Eastern Mediterranean: Climate Change and the Decline of the East, 950-1072

Cambridge University Press, 2012. — 143 p.As a 'Medieval Warm Period' prevailed in Western Europe during the tenth and eleventh centuries, the eastern Mediterranean region, from the Nile to the Oxus, was suffering from a series of climatic disasters which led to the decline of some of the most important civilisations and cultural centres of the time. This provocative study argues that many well-documented but apparently disparate events - such as recurrent drought and famine in Egypt; mass migrations in the steppes of central Asia; and the decline in population in urban centres such as Baghdad and Constantinople - are connected and should be understood within the broad context of climate change. Drawing on a wealth of textual and archaeological evidence, Ronnie Ellenblum explores the impact of climatic and ecological change across the eastern Mediterranean in this period, to offer a new perspective on why this was a turning point in the history of the Islamic world.
