One of the world's leading historians of race relations, George Fredrickson in his newest book probes the history of racial and ethnic diversity in the United States and other parts of the world. Diverse Nationsexplores recent interpretations of slavery and race relations in the United States and introduces comparative perspectives on Europe, South Africa, and Brazil. Notably, the book features groundbreaking work comparing ethnoracial pluralism in France and the United States. In contrast to the similarities of race relations in the United States and South Africa, which both drew rigid domestic color lines, the United States and France have historically diverged greatly in their approaches to racial difference. Yet both are influenced by a common heritage of revolutionary republicanism, extensive immigration, and cultural pluralism. Fredrickson's rich comparisons provide stimulating new insights into the continuing impacts of slavery and beliefs about race upon our increasingly pluralistic societies.
