Juan Carlos Onganía Carballo was President of Argentina from 29 June 1966 to 8 June 1970. He rose to power as dictator after toppling the president Arturo Illia in a coup d'état self-named "Argentine Revolution".
Onganía wanted to install in Argentina a paternalistic dictatorship modeled on Francoist Spain. While preceding military coups in Argentina were aimed at establishing temporary, transitional juntas, the Revolución Argentina headed by Onganía aimed at establishing a new political and social order, opposed both to liberal democracy and to communism, which gave to the Armed Forces of Argentina a leading role in the political and economic operation of the country.
