Abstract:
The objective of this essay is to examine the trajectory of a clandestine organization that, despite being rather active and frequently cited by the academic literature, has not been very visible in Brazilian history: the Military Sector of the PCB, or Antimil. The particularity of this project is to learn about Antimil’s organizational structure in the process of intervening in the Armed Forces between 1929 and 1945. It does not pretend to evaluate its revolutionary efficacy or all the situations in which it was involved, due to the lack of documentation and specific studies. The revelation of its historical configuration, as an organization in the party structure, is the result of exhaustive research and the narratives of some of its members.

Keywords: Antimil. Military Left. PCB.
