Throughout the 20th century, voting was suppressed by Argentina's numerous dictatorial regimes. The dictatorships of José Félix Uriburu (1930–1932) and the so-called "Revolución Libertadora" and "Revolución Argentina", as well as the last military dictatorship (1976–1983), all suppressed voting altogether. In addition, electoral fraud was widespread under the successive governments of the so-called "Infamous Decade". Since the return of democracy in 1983, Argentine elections have been generally deemed as free, fair and transparent, and participation levels remain high, with an average of 70.24% as of 2019.
