A comprehensive history traces the rise and transformation of trade unionism in Britain, charting its origins, legal and constitutional development, internal organisation, and expanding membership. The authors distinguish the general movement from the many particular trade societies, selecting representative documents while omitting numerous local disputes. Attention is given to changing legal status, the incorporation of union practices into public administration, and the formation of a national political organisation promoting social reform. Economic and analytical questions are largely reserved for a separate volume; this work concentrates on institutional evolution, key episodes, and documentary sources.
