Historians of American foreign relations are continuing to expand the ways in which they approach the Cold War. The range of perspectives has evolved thanks to the influence of emerging fields and new emphases in history. The end of the Cold War revealed the many ways in which the conflict was a protracted global war. But it also brought a renewed focus on the domestic implications of Cold War foreign policy for the United States, with researchers delving into topics such as the impact of Cold War policies on state and local governments, the national economy, politics, culture and society, and race relations. This opening of new historical perspectives provides teachers and faculty with an opportunity to approach teaching the Cold War with new pedagogies. One area that has yet to be explored in great depth, even though it goes to the heart of an enduring feature of U.S. foreign relations, is the close association between foreign policy and immigration policy. This article outlines a pedagogical approach that explores the ways in which U.S. immigration legislation was shaped by the ideological and political context of the early Cold War era. The modules and sources included herein are aimed primarily at eleventh- and twelfth grade students of U.S. history-social science (including government and civics) and undergraduate students of U.S. history.
