In both cases, the First World War was a major catalyst. Although events and writings before that war indicate the coming patterns, it was during that war that a great amount of the patterns are well established. Originally published in 1976, this work explores these origins and stresses the interaction between various diverse segments of English society in the formation of the major patterns. The working out of these patterns in the first half of the interwar years is also analysed, again with respect to diverse groupings in Britain.
