Book excerpt: In "Conflict, Peace, and Prosperity in the Name of God," Murat Iyigun explores how longer-term developments influenced the spread of monotheistic religions and how these trends affected other societies and religions. He explores with the statistical methods of economics the way religions shaped the development of societies and framed the conflicts between and within them. Specifically, he asks why and how political power and organized religion became so swiftly and successfully intertwined, and then examines the role of religion in conflict historically, as well as the sociopolitical, demographic, and economic effects of religiously motivated conflicts." Conflict, Peace, and Prosperity in the Name of God "breaks exciting new ground in our understanding of religion and societies, and the conflicts between them."
