The article is about the ideas that came upon the Biological and Social Evolutionism and from Psychology of Masses, during the early beginnings of Brazilian Social Psychology. By the end of the 19th century, Spencer’s and Darwin’s formulations about cultures and races influenced the way social evolutionism’s paradigm was structured, which was launched by Nina Rodrigues. He elaborated descriptions of Brazilian cultural aspects, of human types and theorized about the social movement of Canudos. The scientific racism kept itself hegemonic until the decade of 1930. It lost space, though the racism, maintained itself as an ideological category. In contemporary Brazilian Social Psychology, studies of this matter are scarce.
