There has never been a more important time for a study of the social, economic and political origins of Judaism, Christianity, and Islam, three important world religions which share a common root. This book takes as its starting point the idea that gods, angels, miracles and other supernatural phenomena do not exist in the real world and therefore cannot explain the origins of these faiths. It looks instead at the material conditions at appropriate periods in antiquity and the social and economic forces at work, and it examines the historicity of key figures like Moses, Jesus, and Mohammed.This is a unique book which draws on the research, knowledge and expertise of hundreds of historians, archaeologists, and scholars, to create a synthesis that is completely coherent and at the same time is based on real-world social conditions. It is a book by a non-believer for other non-believers, and it will be a revelatory read, even to those already of an atheist, agnostic, or secularist persuasion.
