This zine is a theoretical and historical explanation of both the idea and reality of “the barricade” in social struggles. Tracing the use of barricades in proletarian struggles in the urban areas of revolutionary Europe in the mid-1800s to their present use in urban street conflicts and indigenous blockades, this zine uses the barricade as an entry-point to discuss wide-ranging but related issues such as blockades, sabotage, and modern capitalism. The writing is relatively dense, but it presents some important points and encourages a deeper consideration of the relationship between theory and tactics.
