Paranoid anti-communism: the conservative reaction to counterculture movements in dictatorial Brazil (1968-1979)

This article aims to discuss the impact of the 1968 movements in Brazil and the development of the so-called "counterculture" in the midst of the National Security Dictatorship(1964-1985), as well as the consequent anti-communist and conservative reaction of political repression and surveillance to these movements that were seen, following the logic of the Doctrine of National Security, as evidence of the subversion of "international communism" present and active in Brazil. We used as sources documents produced by the Information community of the National Security dictatorship centralized in the National Information Service (SNI).
