Morton Keller, a leading scholar of twentieth-century American history, describes the complex interplay between rapid economic change and regulatory policy. In its portrait of the response of American politics and law to a changing economy, this book provides a fresh understanding of emerging public policy for a modern nation.

How did the federal government change from the weak apparatus of the antebellum period to the large, administrative state of the Progressive Era? To Enlarge the Machinery of Government explores the daily proceedings of the U.S. House and Senate from 1858 to 1891 to find answers to this question. Through close readings of debates centered around sponsorship, supervision, and standardization recorded in the Congressional Globe and Congressional Record during this period, Williamjames Hull Hoffer traces a critical shift in ideas that ultimately ushered in Progressive legislation: the willingness of American citizens to allow, and in fact ask for, federal intervention in their daily lives. He describes this era of congressional thought as a "second state," distinct from both the minimalist approaches that came before and the Progressive state building that developed later. The "second state" era, Hoffer contends, offers valuable insight into how conceptions of American uniqueness contributed to the shape of the federal government.
