Argentina, 1956 — military coup attempt
Event Summary
On 9 to 10 June 1956 the retired General Juan Jose Valle led a Peronist military and civilian uprising against the anti-Peronist military government of President Pedro Eugenio Aramburu, whose Revolucion Libertadora had overthrown Juan Peron in September 1955. The rising, prepared as Aramburu's regime banned the Peronist Party, reversed Peron's reforms, and arrested union leaders, was to be signaled by a radio proclamation during a broadcast boxing match, but the government had penetrated the plot in advance and crushed it almost immediately, with only a handful of combat deaths. Aramburu declared martial law and answered with an exceptional wave of summary executions: between 9 and 12 June 1956 some 27 military and civilian participants were shot, including Valle himself at the National Penitentiary and a group of civilians killed extrajudicially in the Jose Leon Suarez massacre.
The severity earned the regime the name la Fusiladora and later motivated the Montoneros' 1970 assassination of Aramburu.
