Infamous Decade
Following the 1917 October Revolution in Russia and the founding of the Profintern, the Argentine Syndicates' Union (USA) was created in March 1922. Although more radical than FORA IX, the USA did not join the Profintern and remained independent from any international affiliation. Meanwhile, the FORA V was in steady decline, and was dissolved shortly before the installation of José Félix Uriburu's dictatorship, which opened up the years of the Infamous Decade.
