In 1946, President Juan Perón came to power. With the emergence of Peronism, more and more labor unions (especially the socialist ones) became Peronist, and anarchist unions - which had already suffered a significant decline during the previous decade - lost all of their remaining strength. The anarchist representation in the labor movement became minimal. When Peronism became the mainstream ideology of the Argentine working people, it replaced the old mainstream labor ideologies (including anarchism, socialism and communism), which never again regained their old importance among the working class. FORA, the traditional anarchist union, was closed as a result of this. In 1952, following the imprisonment and torture of several FORA members, anarchists of all factions launched a campaign to inform the public of this situation. After the violent coup that overthrew Perón in 1955, anarchist periodicals reappeared openly once again, among them "La Protesta" and "Acción Libertaria". However, Argentinian anarchism could never recover as a movement with popular roots.
