These essays document the creation, contestation, and dynamic nature of borders, belonging, and identity during the explosively transnational 20th century. Behnken (Iowa State Univ.) and Wendt (Univ. of Frankfort, Germany) add to their extensive publishing record on the modern history of race and civil rights by assembling 14 essays written by authors whose experiences fittingly cross national, ethnic, and disciplinary boundaries. The essays satisfyingly stay anchored to the overriding sociospatial/identity politics dialectic, but each ventures into its own waters enough to incite readers to explore more of the topic. Eight essays deal with Latin American and African/African American examples, while three essays concern Asia, two pieces are on Europe, and one focuses on the discursive and imagined boundaries of homosexuality. Although the essays span the globe and the century, there are many interesting subthemes that weave through the book—expanding national identity to include minority voices, reimagining the past for contemporary political control, and navigating the frontier of imagined boundaries, to name a few. Scholars and students in the social sciences with interests in transnationalism, nation building, or identity politics will find this to be a thought-provoking treat. Summing Up: Highly recommended. Upper-level undergraduates to faculty.
