The UNESCO Project (1950) placed Brazil at the center of discussions on race relations in the world. Seen from the perspective of racial democracy, national pride, Brazil was the subject of sociological and anthropological research on forms of social and racial harmony that could be a key element against ethnic-racial conflicts, such as the Jewish Holocaust during World War II. However, the Brazilian internal reality has nothing to do with the alleged racial democracy propagated by the world, denying, dehumanizing and exterminating the black population across the country. In doing so, this research approaches the international thought around the Brazilian racial democracy in opposition to the domestic reality of the country of genocide of the black people. This fact highlights the fallacy of reading the State s International Relations as a unitary and rational actor in the International System. Likewise, it strives to demonstrate how the myth of racial democracy and the epistemicide against afrodiasporic intellectuals tends to deny its participation in the interpretation of Brazil s place in the world in the construction of the International Relations course in the country. To this end, this article is divided into three distinct sections: the first addresses the concepts of race, whiteness and coloniality as inherent to Brazil and the IR academy. The second section presents the UNESCO Project, its debates and conflicts, as a possibility to shed light on the Brazilian non-democratic racial reality. Finally, the third section is interested in connecting the UNESCO Project with the IR academy in the country, in order to express how the discipline ignores domestic reality in the name of state unity and rationality.
