The passage of the Reform Bill of 1867 is one of the major problems in nineteenth-century British history. Mr Cowling provides a full-scale explanation, based on a wide range of archive material, including four major manuscript collections not previously used. Mr Cowling pays equal attention to the view taken by Parliament of the class structure and to the ambitions and strategies of politicians in Parliament and outside. He sets this detailed historical narrative in an analytical framework, the assumptions of which he discusses at length.
