This talk examines the changing material terrain of urban struggle today. The rapid militarization of the police, the changing spatial patterns of segregation, the embeddedness of ubiquitous computing into into the surveillance architecture, and the heightened centrality of urban spaces to global flows of capital are all changing the political space of the city today. What do these changes offer for struggle? How are various tactics of struggle – strikes, blockades, marches, occupations, and so on – made more or less amenable to political struggle today? What traditional modes of struggle are becoming obsolete in the face of contemporary changes, and what new potentials are opening up? This presentation will examine these questions and suggest an outline for contemporary urban struggle.
