The great historian D.C. Moore's masterpiece, long unavailable. It is an essential fulcrum for all attempts to explain the nature of the 19th century English political system, and the great and continuous changes that occurred within that system as a preface to modern English society. Moore shows that the principal factor which changed the Victorian political system were those that derived from its working in the context of the changing economic and social environment in the industrial revolution and its immediate aftermath. The book reflects the premise that the key to the nature of any political system lies in the relationship between the formal political structure and the structure of the effective groups within that society.
