The province of Tucumán, Argentina, has been used as a test case for the fallacious “theory of the two demons” because it is both where a guerrilla movement formed in 1974 and where the country’s first clandestine detention center was established in the “escuelita” of Famaillá during “Operativo Independencia” in 1975. This “theory” reduces the conflict in the province to a confrontation in the Tucumán hills between no more than 150 combatants of the People’s Revolutionary Army (Ejército Revolucionario del Pueblo, ERP) and 5,000 soldiers of the Argentine Army. This, however, largely conceals the social catastrophe suffered by Tucumán and the high levels of conflict that had already been taking place for more than a decade. Previously, in August 1966, the provincial territory had been militarized by the new dictatorial government led by Juan Carlos Onganía. On that occasion, militarization sought to guarantee the closure of sugar mills. This generated an unprecedented economic and social crisis. Between 1966 and 1968, eleven mills were closed out of a total of twenty-seven, more than 50,000 jobs were eliminated in the sugar agro-industry alone, medium and small sugarcane producers were severely affected, and more than a quarter of the total population of the province was forced to emigrate in search of new sources of work. Such were the root causes of social conflict, led mainly by the sugar working class assembled in the Tucumán Workers Federation of the Sugar Industry (Federación Obrera Tucumana de la Industria Azucarera, FOTIA), which the 1976 dictatorship was intent on reining in.
