Pedro Eugenio Aramburu

Pedro Eugenio Aramburu was a de facto president of Argentina from 1955 to 1958. He came to power after displacing Eduardo Lonardi, who had sought a compromise with Peronism. Aramburu's administration was a military dictatorship that aimed to restore constitutional government.12

Aramburu's government took a strong anti-Peronist stance, dissolving Juan Perón's party and placing labor unions under state control. Despite these efforts, Peronists remained influential. In 1958, they supported Arturo Frondizi for president, who promised to readmit them to political life. Frondizi's presidency focused on economic development but led to inflation and restrictions on credit, increasing industrial difficulties.2

In 1962, Peronists gained significant electoral ground, leading the armed forces to withdraw support from Frondizi and establish a government under José María Guido. This period was marked by confusion and infighting between military factions. In 1970, during a later military government, the Montoneros, a Peronist group, captured and killed Aramburu.23
