A descendant of Italians and Spaniards, he was born to Fernando Doratioto and Amélia Monteoliva Guillén in Atibaia.[2]
He graduated in History and Social Sciences in 1979 and 1982, respectively, through the University of São Paulo's Faculty of Philosophy, Languages and Human Sciences. He has a master's degree and a PhD in History of International Relations by the University of Brasília. He was previously a professor of the Universidade Católica de Brasília and is currently a professor in American History at the University of Brasília's History Department.
In his most well known work, Maldita Guerra [Damned War], Doratioto presents the history of the Paraguayan War in detail, going against explanations which attributed to British imperialism a key role in fomenting the war. [3] The work defends that well-prepared armed forces are a necessary tool for States to affirm their sovereignty, and that at the same time the envolvement of military officers in politics is negative, for it tends to lead to neglect in the country's defense apparatus.[citation needed] In May 2020, Doratioto announced that this book would be republished in that year, in an expanded edition, in celebration of the 150 years of the end of the Paraguayan War.
He is a corresponding member of the Brazilian Historic and Geographic Institute, the Paraguayan Academy of History, the National Academy of History (ofArgentina), and of the Brazilian Military Historic and Geographic Institute.
