Later immigration, from 1908 on, was not so much influenced by that race discussions and Brazil attracted, besides Europeans, more immigrants from Lebanon, Syria and Japan, for example. The Brazilian government, as was commonplace at that time, endorsed positions expressed by Brazilian intellectuals and scientists. An example is a text, written by Oliveira Vianna, that was issued as introductory material to 1920 Census results. Many pages of Vianna's work were dedicated to the discussion of a "pure race" of white Brazilians. According to the text, written by Oliveira Vianna, the first Portuguese colonists who came to Brazil were part of the blond Germanic nobility that ruled Portugal, while the dark-haired "poor" Portuguese only came to Brazil later, in the 17th and especially the 18th century. According to Oliveira Vianna, the blond Portuguese of Germanic origin were "restless and migratory", and that's why they emigrated to Brazil. On the other hand, the Portuguese of darker complexions were of Celtic or Iberian origin and came when the Portuguese settlement in Brazil was already well established, because, according to him, "The peninsular brachyoids, of Celtic race, or the dolicoides, of Iberian race, of sedentary habits and peaceful nature, did not have, of course, that mobility nor that bellicosity nor that spirit of adventure and conquest". The text reported the different levels of intelligence found among blacks and highlights the existence of "lazy blacks" (Gêgis and Angolans) or "laborious blacks" (Timinins, Minas, Dahomeyanos) and also the existence of "peaceful and obedient blacks" and of "rebels and fierce" ones. Vianna also compares the "morality" and intellectual level found among blacks and reports that Gêgis, Krumanos and Cabindas revealed the "mental inferiority, typical from the lowest types of the black race". In 1933, Brazilian anthropologist Gilberto Freyre published his famous book "Casa-Grande & Senzala" ("The Masters and the Slaves"). The book appeared at a moment when there was a widespread belief among social scientists that some races were superior to other ones, and in the same period when the Nazi Party in Germany was on the rise. Freyre's work was very important to change the mentality, especially of the white Brazilian elite, who considered the Brazilian people as "inferior" because of their African and Amerindian ancestry.
