Errico Malatesta was an Italian anarchist propagandist and revolutionary socialist. He edited several radical newspapers and spent much of his life exiled and imprisoned, having been jailed and expelled from Italy, Britain, France, and Switzerland. Originally a supporter of insurrectionary propaganda by deed, Malatesta later advocated for syndicalism. His exiles included five years in Europe and 12 years in Argentina. Malatesta participated in actions including an 1895 Spanish revolt and a Belgian general strike. He toured the United States, giving lectures and founding the influential anarchist journal La Questione Sociale. After World War I, he returned to Italy where his Umanità Nova had some popularity before its closure under the rise of Mussolini.

Propaganda of the deed is specific political direct action meant to be exemplary to others and serve as a catalyst for revolution.
