Brazil has recently enacted sweeping policies against racial inequality, including a mandate to teach African and Afro-Brazilian history and culture in schools across the country. This article analyzes Afro-Brazilian activists' heteroglossic engagement with recent legal and social changes while leading teacher-training courses. I demonstrate how participants juxtapose long-held narratives of racial mixture with the discourse of new antiracist legislation and, in doing so, construct antiracist positions in relation to Brazil's competing racial ideologies.
