During the late 1950's, an anti-communist offensive took place in Uruguay promoted by several social actors, all of them with heterogeneous backgrounds and characteristics. Its implementation coincided with new local, regional and global scenarios and implied the continuation and deepening of certain practices displayed at the beginning of the Cold War, as well as the incorporation of new leaders and conflict arenas. Based on the comparison and collation of primary sources produced by local actors, this article examines the anticommunist offensive drawing attention to its promoters and main topics. In this work-frame the question of the beginnings and decline of this anti-communist offensive incited by liberalconseréatives (self-identified as "democrats") is raised and an explanation about the reception of the "internal" enemy rhetoric by non-politicized groups is proposed.
