Juan Carlos Onganía Carballo (Spanish pronunciation:  ; 17 March 1914 – 8 June 1995) 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 Revolución Argentina. 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.
