My project studies the trajectories of military personnel who were expelled from the armed forces and persecuted during Brazil’s military dictatorship (1964-1985). For decades, scholars studying the Brazilian dictatorship have emphasized opposition between civil society and the institution of the armed forces, a division that my project challenges. This binary framework lays the forces, together with some conservative groups such as national and international private sectors, on one side of the spectrum as the enforcers and supporters of military rule; while on the other side of the spectrum, resisting authoritarianism are progressive sectors such as the student and the union movements. This interpretation, which marked the most important works on the era, is not entirely wrong, as the dictatorship pitted military against civilian. However, it is incomplete and, as a result, portrays this period in Brazilian history in misleading fashion. My research builds from previous works, while also redirecting our attention to the reach of the military dictatorship into sectors of Brazilian society often thought to have been shielded from it, including and especially the military itself. The project examines dissent and repression within the armed forces, focusing on the trajectories of thousands of soldiers and officers expelled from the forces as military leaders consolidated decades of authoritarian political power.
