In Florence he founded the weekly anarchist paper "La Questione Sociale" ("The Social Question") in which his most popular pamphlet, "Fra contadini" ("Among Farmers"), first appeared. Malatesta went back to Naples in 1884—while waiting to serve a three-year prison term—to nurse the victims of a cholera epidemic. Once again, he fled Italy to escape imprisonment, this time heading for South America. He lived in Buenos Aires from 1885 until 1889, resuming publication of "La Questione Sociale" and spreading anarchist ideas among the Italian émigré community there. He was involved in the founding of the first militant workers' union in Argentina and left an anarchist impression in the workers' movements there for years to come.
