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

Insurrectionary anarchism
Insurrectionary anarchism is a revolutionary theory and tendency within the anarchist movement that emphasizes insurrection as a revolutionary practice. It is critical of formal organizations such as labor unions and federations that are based on a political program and periodic congresses. Instead, insurrectionary anarchists advocate informal organization and small affinity group based organization. Insurrectionary anarchists put value in attack, permanent class conflict and a refusal to negotiate or compromise with class enemies.
