This first volume of Sir Arthur Bryant's wonderfully readable History of Britain and the British People starts with the islands' geographical formation and ends with the close of the fifteenth century. The Atlantic flood cut Britain off from mainland Europe and made it an island. Colonisation in the form of a succession of sea-born invaders took place over thousands of years. There were nomadic peoples from Asia, Africa, Romans, Vikings, evangelists with their message of Christianity and Normans. Upon this foundation civilization was built. Bryant examines aspects of medieval life and finishes with the building of the last great medieval churches at the end of the fifteenth century.
