How did racism evolve in different parts of the Portuguese-speaking world? How should the impact on ethnic perceptions of colonial societies based on slavery or the slave trade be evaluated? What was the reality of inter-ethnic mixture in different continents? How has the prejudice of white supremacy been confronted in Brazil and Portugal? And how should we assess the impact of recent trends of emigration and immigration? These are some of the major questions that have structured this book. It both contextualises and challenges the visions of Gilberto Freyre and Charles Boxer, which crystallised from the 1930s to the 1960s, but which still frame the public history of this topic. It studies crucial issues, including recent affirmative action in Brazil or Afro-Brazilian literature, blackness in Brazil compared with Colombia under the dynamics of identity, recent racist trends in Portugal in comparative perspective, the status of native people in colonial Portuguese Africa, discrimination against forced Jewish converts to Christianity and their descendants in different historical contexts, the status of mixed-race people in Brazil and Angola compared over the longue dur''ee, the interference of Europeans in East Timor''s native marriage system, the historical policy of language in Brazil, or visual stereotypes and the proto-ethnographic gaze in early perceptions of East African peoples. The book covers the gamut of inter-ethnic experiences throughout the Portuguese-speaking world, from the sixteenth century to the present day, integrating contributions from history, sociology, social psychology, anthropology, literary, and cultural studies. It offers a radical updating of both empirical data and methodologies, and aims to contribute to current debates on racism and ethnic relations in global perspective.
