The entity remained influential until its shutdown by the military regime of 1964–85, when dozens of union leaders, including student and then-president of DCE Mario de Souza Prata, were murdered. In the late-1970s, given a gradual political opening, academic centers such as the DCE were given permission to function once again. Among the students that participated in the DCE's reactivation are Mário Furley Schimidt and some member of popular Brazilian comedy show Casseta & Planeta, like Marcelo Madureira, Beto Silva and Hélio de la Peña. Besides the DCE, minor academic centers (CAs) act as students representative organs for each course: the Carlos Chagas Academic Center for the College of Medicine, the Polytechnic School Academic Center of Engineering, the Cândido de Oliveira Academic Center for the College of Law Studies, the Max Planck Academic Center for the Institute of Physics and the Academic Directory for the School of Chemistry, to cite the most notable. The infamous episode known as "Massacre da Praia Vermelha" (Red Beach Massacre) was a hallmark the history of Brazilian student unions. At dawn of September 23, 1968, squads from the military government invading the old facility of then-National College of Medicine and savagely beat all students sheltered there. There was also massive depredation of public patrimony, as the action disenabled several of the college's laboratories and administrative sectors. Around 600 students were gathered to protest against the government's arbitrary and oppressive actions (ex.: the shutdown of DCE and UNE, the increase in meal prices) and to vindicate the release of Law student Rodrigo Lima, arrested for 35 days in the "Batalhão de Guardas do Exército" (Army Squad Battalion).
