Argentine general election of 1973 was held on 23 September . Turnout was 85.5 % , and it produced the following results : The jubilation that followed the May 25 , 1973 , return to democracy ( following over six and a half years of military rule ) was soon clouded by political friction and unforeseen events . President Héctor Cámpora , who took his Oath of Office in the presence of Cuban leader Osvaldo Dorticós and Chilean leader Salvador Allende — both consular figures in Latin American Marxism — promptly declared a near-blanket amnesty for the several hundred political prisoners held by Alejandro Lanusse 's regime ( many in inhospitable camps such as the one in Trelew , scene of a 1972 mass execution ) . Cámpora also made controversial appointments , such as Rodolfo Puiggrós as President of the University of Buenos Aires , Esteban Righi as Minister of the Interior ( overseeing law enforcement ) and Julio Troxler as Assistant Police Chief of Buenos Aires - all former defense attorneys linked to the violently left-wing Montoneros . A number of left-wing lawyers were also elected to prominent elected posts across the nation , notably Oscar Bidegain ( Governor of Buenos Aires Province ) , Ricardo Obregon Cano ( Governor of Córdoba Province ) and Alberto Martínez Baca ( Governor of Mendoza Province ) , among others . This new-found prominence among the Argentine left encouraged an increasingly violent reaction among the far right . Among Cámpora 's appointees was one insisted on by his patron , Juan Perón : José López Rega , a former policeman with an interest in the occult close to the Perón household since 1965
