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 a number of 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).
