Historians of immigration and ethnicity in the United States have typically devoted little attention to Greek Americans compared to the extensive historical literature produced about their Irish, Italian, and German counterparts. From acclaimed historian Kostis Karpozilos, Red America provides a deeply researched correction to Western perspectives on Greek American interaction with social, political, and economic change. 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 the everyday experiences of immigrants, tracing ethnic radicalism from the boundaries of a specific community to the epicenter of American social and political history.
