The founding of the first universities in the first decades of the 20th century in Brazil emerged from a context of public education reforms and expansion that modified the relationship between intellectuals and the public sphere in Brazil. The representation of national pasts was the object of prolific public debate in the social sciences and literature and fine arts through social and historical essays, pushed mostly from the 1920’s to the 1950’s, such as Gilberto Freyre’s, The Master and the Slaves (Casa Grande e Senzala, 1936) and Sérgio Buarque de Holanda’s Roots of Brazil (Raízes do Brasil, 1936). Just after the 1950s, universities expanded nationally, and new resources were available for academic and scientific production, such as libraries, archives, scientific journals, and funding agencies (namely CNPQ, CAPES and FAPESP). In the field of history, these effects would have a greater impact in the 1960s and 1970s with the consolidation of a National Association of History, the debate over curricula and required content, and the systematization of graduate programs (thanks to the University Reform of 1968, during the military dictatorship). Theses, dissertations, and monographs gradually gained ground as long social essays lost their prestige, seen as not befitting the standards of disciplinary historiography as defined in the graduate programs such as a wider empirical ground and more accurate time frames and scopes. Through their writing in more specialized formats, which moved away from essays and looked into the great Brazilian historical problems, historians played an important role in the resistance against the authoritarian regime (1964–1985) and, above all, contributed to a debate on the role of silenced minorities regarding redemocratization.
