A comprehensive study of the Progressive movement, Reinventing "The People"contends that the persistence of class conflict in America challenged the very defining feature of Progressivism: its promise of social harmony through democratic renewal.

Shelton Stromquist profiles the movement's work in diverse arenas of social reform, politics, labor regulation and so-called race improvement. While these reformers emphasized different programs, they crafted a common language of social reconciliation in which an imagined civic community--"the People"--would transcend parochial class and political loyalties. But efforts to invent a society without enduring class lines marginalized new immigrants and African Americans by declaring them unprepared for civic responsibilities. In so doing, Progressives laid the foundation for twentieth-century liberals' inability to see their world in class terms and to conceive of social remedies that might alter the structures of class power.
