Marx and Engels saw very clearly the part that the criminal elements would play in any uprising, and as early as 1847 they wrote in the Communist Manifesto: "The 'dangerous class,' the social scum, that passively rotting mass thrown off by the lowest layers of old society, may, here and there, be swept into the movement by a proletarian revolution; its conditions of life, however, prepare it far more for the part of a bribed tool of reactionary intrigue."[22] The truth of this statement has been amply illustrated in the numerous outbreaks that have occurred since it was written. The use by the Bakouninists in Spain of the criminal elements there, the repeated exploits of the police agents in discrediting every uprising by encouraging the criminal elements to outrageous acts, and the terrible barbarities of the criminal classes at the time of the Paris Commune are all examples of how useful to reaction the rotting layers of old society may become. Even when they do not serve as a bribed tool of the reactionary elements, their atrocities, both cruel and criminal, repel the self-respecting and conscientious elements. They discredit the real revolutionists, who must bear the stigma that attaches to the inhuman acts of the "dangerous class."
That the European governments have used the terrorists in exactly this manner in order to discredit popular movements, is not, I think, open to any question. The money of the anarchists' bitterest enemy has helped to make anarchy so well known. The politics of Machiavelli is the politics of nearly every old established European government. It is the politics of families who have been trained in the profession of rulership. And this mastership, as William Morris has said, has many shifts. And one that has been most useful to them is that of subsidizing those persons or elements who by their acts promote reaction. In Russia it is an old custom to foment and provoke minor insurrections. Police agents enter a discontented district and do all possible to irritate the troublesome elements and to force them "to come into the street." In this manner the agitators and leaders are brought to the front, where at one stroke they may all be shot. Furthermore, the police agents themselves commit or provoke such atrocious crimes that the people are terrified and welcome the strong arm of the Government. Literally scores of instances might be given where, by well-planned work of this sort, the active leaders are cut down, the sources of agitation destroyed, and through the robberies, murders, and dynamite outrages of police agents the people are so terrified that they welcome the intervention of even tyranny itself.
