Propaganda of the deed is the idea that action itself communicates revolutionary analysis — that a well-chosen act demonstrates what words can only describe. The concept emerged in the anarchist movement in the 1870s and 1880s, associated with the Italian and Russian revolutionary traditions, and was initially articulated by Carlo Cafiero, Errico Malatesta, and others at the 1876 Berne Congress of the International.
In its original formulation, the concept was broad: any act that demonstrated the possibility and desirability of a world without domination counted as propaganda of the deed. A commune that organized itself without hierarchy, a strike that seized a workplace, an expropriation that redistributed wealth — these were propaganda because they showed, rather than merely argued, that alternatives to the existing order were possible.
The concept became associated almost exclusively with assassination and bombing in the 1890s, a narrowing that has distorted its reception since. The broader meaning — that action is itself a form of communication — remains central to anarchist practice. Direct action is propaganda of the deed whenever the action itself makes visible what the existing order makes invisible: that cooperation does not require hierarchy, that resistance does not require permission, that the structures of domination are sustained by compliance and can be disrupted by its withdrawal.
