This essay reviews four books on the Progressive Era, and draws lessons from those books to help explain contemporary political events. It explores topics such as proportional representation, efficiency of service delivery, business-driven reforms, and voter heterogeneity. All of these books provide a meaningful understanding of cities in the Progressive Era (1890s-1920s) and beyond. However, the issues and lessons from a century ago still challenge us today, so we may be in a new “Gilded Age” and headed toward yet another era of progressivism
