Anarchism and violence have become closely connected in popular thought, in part because of a concept of "propaganda of the deed". Propaganda of the deed, or attentát, was espoused by leading anarchists in the late nineteenth century, and was associated with a number of incidents of violence. Anarchist thought, however, is quite diverse on the question of violence. In the name of coherence some anarchists have opposed coercion, while others have supported it, particularly in the form of violent revolution on the path to anarchy. Anarchism includes a school of thought which rejects all violence (anarcho-pacifism).
Many anarchists regard the state to be at the definitional center of structural violence: directly or indirectly preventing people from meeting their basic needs, calling for violence as self-defense.
Perhaps the first anarchist periodical was named The Peaceful Revolutionist, a strain of anarchism that followed Tolstoy's pacifism.
Late in the 19th century, anarchist labor unions began to use the tactic of general strike. This often resulted in violence by both sides and some of the strikes even resulted in the deaths of striking workers, their replacements and security staff.
In this climate, some anarchists began to advocate and practice terrorism or assassination, which they referred to as propaganda of the deed. In many cases, newspapers blamed anarchist terrorism on immigrant naïvety, but scholar Richard Bach Jensen explained that "the emigrant experience may have heightened a pre-existing radicalism or given more precise configuration to its violent expression." United States President William McKinley was assassinated by Leon Czolgosz, a registered Republican who, after his arrest, claimed he had been influenced by the writings of Emma Goldman and others. Czolgosz' actions were widely condemned by anarchists, but the media widely characterized Czolgosz as a typical anarchist even though he had never actually belonged to any anarchist organization. Goldman spoke sympathetically of him and described his act as the result of a violent society. Her defense of Czolgosz was met with open hostility from most of the anarchist press.
Depictions in the press and popular fiction helped create a lasting public impression that anarchists are violent terrorists. This perception was enhanced by events such as the Haymarket Riot, where anarchists were blamed for throwing a bomb at police who came to break up a public meeting in Chicago. The writer J. R. R. Tolkien, in a letter to his son, briefly described anarchy "philosophically understood" as "meaning abolition of control not whiskered men with bombs."
Anarcho-pacifism (also pacifist anarchism or anarchist pacifism) is a form of anarchism which completely rejects the use of violence in any form for any purpose. Important proponents include Leo Tolstoy and Bart de Ligt. Mohandas Gandhi is an important influence.
Henry David Thoreau, though not a pacifist himself, influenced both Leo Tolstoy and Mohandas Gandhi's advocacy of Nonviolent resistance through his work Civil Disobedience.
At some point anarcho-pacifism had as its main proponent Christian anarchism. The first large-scale anarcho-pacifist movement was the Tolstoyan peasant movement in Russia. They were a predominantly peasant movement that set up hundreds of voluntary anarchist pacifist communes based on their interpretation of Christianity as requiring absolute pacifism and the rejection of all coercive authority.
"Dutch anarchist-pacifist Bart de Ligt’s 1936 treatise The Conquest of Violence (with its none too subtle allusion to Kropotkin’s The Conquest of Bread) was also of signal importance." "Gandhi's ideas were popularised in the West in books such as Richard Gregg's The Power of Nonviolence (1935), and Bart de Ligt's The Conquest of Violence (1937).
As a global movement, anarchist pacifism emerged shortly before World War II in the Netherlands, Great Britain and the United States and was a strong presence in the subsequent campaigns for nuclear disarmament.
Anarchism encompasses a variety of views about violence. The Tolstoyan tradition of non-violent resistance is prevalent among some anarchists. Ursula K. Le Guin's novel The Dispossessed, a fictional novel about a society that practises "Odonianism", expressed this anarchism:
Odonianism is anarchism. Not the bomb-in-the-pocket stuff, which is terrorism, whatever name it tries to dignify itself with, not the social-Darwinist economic 'libertarianism' of the far right; but anarchism, as prefigured in early Taoist thought, and expounded by Shelley and Kropotkin, Goldman and Goodman. Anarchism's principal target is the authoritarian State (capitalist or socialist); its principle moral-practical theme is cooperation (solidarity, mutual aid). It is the most idealistic, and to me the most interesting, of all political theories.
Emma Goldman included in her definition of Anarchism the observation that all governments rest on violence, and this is one of the many reasons they should be opposed. Goldman herself didn't oppose tactics like assassination in her early career, but changed her views after she went to Russia, where she witnessed the violence of the Russian state and the Red Army. From then on she condemned the use of terrorism, especially by the state, and advocated violence only as a means of self-defense.
Some anarchists see violent revolution as necessary in the abolition of capitalist society, while others advocate non-violent methods. Errico Malatesta, an anarchist-communist, propounded that it is "necessary to destroy with violence, since one cannot do otherwise, the violence which denies [the means of life and for development] to the workers." As he put it in Umanità Nova (no. 125, September 6, 1921):
It is our aspiration and our aim that everyone should become socially conscious and effective; but to achieve this end, it is necessary to provide all with the means of life and for development, and it is therefore necessary to destroy with violence, since one cannot do otherwise, the violence that denies these means to the workers.
Anarchists with this view advocate violence insofar as they see it to be necessary in ridding the world of exploitation, and especially states.
Pierre-Joseph Proudhon argued in favor of a non-violent revolution through a process of dual power in which libertarian socialist institutions would be established and form associations enabling the formation of an expanding network within the existing state-capitalist framework with the intention of eventually rendering both the state and the capitalist economy obsolete. The progression towards violence in anarchism stemmed, in part, from the massacres of some of the communes inspired by the ideas of Proudhon and others. Many anarcho-communists began to see a need for revolutionary violence to counteract the violence inherent in both capitalism and government.
Anarcho-pacifism is a tendency within the anarchist movement which rejects the use of violence in the struggle for social change. The main early influences were the thought of Henry David Thoreau and Leo Tolstoy. It developed "mostly in Holland [sic], Britain, and the United States, before and during the Second World War". Opposition to the use of violence has not prohibited anarcho-pacifists from accepting the principle of resistance or even revolutionary action provided it does not result in violence; it was in fact their approval of such forms of opposition to power that lead many anarcho-pacifists to endorse the anarcho-syndicalist concept of the general strike as the great revolutionary weapon. Later anarcho-pacifists have also come to endorse to non-violent strategy of dual power.
Other anarchists have believed that violence (especially self-defense) is justified as a way to provoke social upheaval which could lead to a social revolution.
