Historians of immigration and ethnicity in the United States have typically devoted little attention to Greek Americans, while popular narratives depict them as indifferent or hostile to political and social radicalism. From acclaimed historian Kostis Karpozilos, Red America provides an alternative narrative of the Greek American experience. Focusing on the history of the Greek American Left from the beginning of the twentieth century to the Cold War, this volume uncovers the threads that bound notions of radical social change to everyday immigrant life, tracing ethnic radicalism from the boundaries of a specific community to the epicenter of American social and political history.
