Oliveira Viana in his 1920 book As populações meridionais do Brasil ("The Southern Populations of Brazil") offered lavish praise of Gobineau for his denunciation of miscegenation and his disparaging remarks about black and Indian Brazilians.[191] Vianna's solution was a plan to "Aryanise" Brazil by bringing in millions of fair-skinned European immigrants and thus achieve the "embranquecimento" of Brazil.[191] Vianna served as the education minister under the dictatorship of Getúlio Vargas, where he was well known for his advocacy of the advantages of "Aryan" immigration to Brazil.[191]
