This book is about governmental change in America. It examines the reconstruction of institutional power relationships that had to be negotiated among the courts, the parties, the president, the Congress and the states in order to accommodate the expansion of national administrative capacities around the turn of the twentieth century. Stephen Skowronek argues that new institutional forms and procedures do not arise reflexively or automatically in response to environmental demands on government, but must be extorted through political and institutional struggles that are rooted in and mediated by pre-established governing arrangements. As the first full-scale historical treatment of the development of American national administration, this book will provide a useful textbook for public administration courses.
