'We have long been familiar with the famines that struck Egypt in the mid-1000s, but Ellenblum is the first to show how these are part of a broad regional pattern. This comprehensive and clearly argued book advances our understanding of the complex political, social, and economic processes of the late tenth and eleventh century in SW Asia and, more broadly, our capacity to link these processes to those underway in other parts of Eurasia.'
