Based on extensive use of primary evidence, this is the first study of interwar British communism to set the communist experience within the framework of the life cycle. Communism offered a complete identity that could reach into virtually all aspects of life; the Party sought influence even over members' personal conduct, moral codes, health and diet, personal hygiene, and aesthetic judgements. The British Communist Party (CPGB) sought to address the communist experience through all of the principal phases of the life cycle, and its reach therefore extended to take in children, youth, and the various aspects of the adult experience, including marital and kinship relations. The book also considers the contention that the Communist Party functioned as a ‘political religion’ for some joiners who opted to enter the congregation of the communist devoted.
