The Argentine military emerged as a major political force with its overthrow of the Irigoyen government in September, 1930. It remains an active political force to this day. The role the military has played during this period has varied in terms of the specific objectives sought, the methods used, and the intensity of its action, but at no time did it cease to be a political force, at no time have the governing authorities whether military or civilian been able to discount its desires or demands. The purpose of this paper is to analyze the nature of the role the military played between 1930 and 1958 and to attempt an assessment of its more recent activities. As used in this paper, the term “military” will refer to the officers, active and retired, of the three armed services. The oneyear conscripts who have comprised the bulk of the enlisted men in the army and a substantial part of those of the navy and air force have never been initiators of political action.
