Although women's rights, disarmament initiatives, and other contemporary social movements receive substantial critical attention, no new work on American reformism as a whole has been published since the late 1960s. In this wide-ranging history, David De Leon brings us up-to-date and offers fresh insights on the social transformations that continue to reshape our society. He traces the evolution of modern reform movements, analyzing their leadership, goals, and achievements, and presents selections from speeches and writings that vividly capture the reforming spirit.
