Saving Europe offers a transnational history of American aid and intervention in Europe between 1914 and 1924, a period when the US simultaneously tightened its borders and expanded its reach. In that crucial decade after the outbreak of World War I, Americans saw themselves in a novel role as protectors of European cultural heritage and as rescuers of vulnerable populations, making them worthy successors to earlier global powers. Saving Europe shines a light on how the US wielded "soft" power in the interwar period through food, dollars, and reconstruction projects. In case studies of Belgium, France, Austria, Germany, and Poland, it traces the development of American views of their role in the wider world as well as European responses to this intervention, providing valuable context for later US global aid and development regimes after World War II.
