The End of Anarchism by Galliani
Galleani was an Italian anarchist active in the United States from 1901 to 1919, viewed by historians as an anarchist communist and an insurrectionary anarchist. He is best known for his enthusiastic advocacy of "propaganda of the deed", i.e. the use of violence to eliminate "tyrants" and "oppressors" and to act as a catalyst to the overthrow of existing government institutions.
