This dissertation maps the relations between the Antropophagy(Anthropophagic Movement) and the Eugenics Movement in Brazilian interwar context. Eugenics, is the science of racial improvement, predominated in bothglobal and national scientific circles, while Anthropophagy represented, in thecultural field, an expansion and ideological maturation of Brazilian Modernism s.Similar to the generation of the 1870s, which sought to interpret Brazil through the application of scientific principles in literary criticism, in the 1920s, cultural and racial concerns resurfaced with the same lexicon. The country s literary and scientific intelligentsia, driven by a modernizing surge from the State (which was maximized after the First World War), gained new impetus to reverse the image of Brazil as a backward nation due to fatalistic claims about the climate,miscegenation, and colonial heritage. Simultaneously, there was a desire to address the lack of cohesion among ethnic elements, intensified after a significant European immigration. Through the analysis of the São Paulo s literary journal Revista de Antropofagia and its literary supplements in other states (often overlooked bycritics), it is possible to perceive that both groups, with heterogeneous and eveninternally divergent perspectives, found a confluence when discussing the formation of a Brazilian race that is essentially strong, miscegenation-driven, and endowed with moral and spiritual unity. This convergence between Anthropophagy and eugenics contributes to the understanding of why the valorization of Black and Amerindian heritage within Modernism s Brazilianness (incorporated by the Statestarting from 1930) far from breaking with racial prejudices, culminating in the legitimation of a peculiar model of neutralizing otherness through devouring.
