In March 1976 the Argentine military seized power following a coup d'état. The military junta then implemented what was called the National Reorganization Process which was a set of policies used by the regime to destroy left-wing guerrilla forces and oppress resistance to its rule. The process included kidnappings, torture and murder. Meanwhile the Montoneros, a leftist guerilla group, responded violently to the junta and its actions as they enlisted other Argentines to join their campaign against the regime. Those enlisted included young, left-wing, politically active students from the organization named the Unión de Estudiantes Secundarios (Union of High School Students) of La Plata. The UES was committed to achieving school reforms and other political reforms, through demonstrations and protests that irked the ruling regime. Tue UES also supplied the People's Revolutionary Army fighting to secede Tucumán Province with fighters.[1]
