In The Poverty of the World, Sheyda Jahanbani brings together the histories of United States foreign relations and domestic politics to explain why, during a period of unprecedented affluence, Americans rediscovered poverty and supported major policy initiative to combat it. Revisiting a moment of triumph for American liberals in the 1940s, Jahanbani shows how the United States's newfound role as a global superpower prompted novel ideas among liberal thinkers about how to address poverty and generated new urgency for trying to do so. Their sense of responsibility about deploying American knowledge and wealth as a beneficent force in the world, produced such foreign aid programs as the Peace Corps.

Drawing on a wide variety of archival material, Jahanbani reinterprets the lives and work of prominent liberal figures in postwar American social politics to show the global origins of their ideas. By tracing how American liberals invented the problem of "global poverty" and executed a war against it, The Poverty of the World sheds new light on the domestic impacts of the Cold War, the global ambitions of American liberalism, and the way in which key intellectuals and policymakers worked to develop an alternative vision of United States empire in the decades after World War II.
