Was it because a Roman emperor, Constantine, who was master of the Western world at the time, became a sincere convert to Christianity and set out to Christianize the whole world in order to save it?
Or was it because, as a great emperor, Constantine needed a great religion, and in comparison to the pagan gods, Christianity, despite being a minority sect, was an avant-garde religion unlike anything seen before?
Or was it because Constantine limited himself to helping the Christians set up their Church, a network of bishoprics that covered the vast Roman Empire, and that gradually and with little overt resistance the pagan masses embraced Christianity as their own religion?
In the course of deciding between these explanations Paul Veyne sheds fresh light on one of the most profound transformations that shaped the modern world - the Christianization of the West. A bestseller in France, this book will appeal to a wide readership interested in history, religion and the rise of the modern world.
