Since its founding in 2005, the Centre for Research Architecture (CRA) at Goldsmiths, University of London, has brought together a diverse group of architects, artists, urbanists, geographers, lawyers, scientists, journalists and activists to develop research methodologies and investigative techniques to address contemporary spatial politics. Militant Media, the second volume in CRA’s series of publications, engages with the ethical and political implications of media and technology in relation to contemporary conflicts. In doing so, it also reflects upon the changing role of media in justice and human rights campaigns, examining a range of topics from the use of images in campaigning to the investigative potential of digital materials. In addition to critical and theoretical reflections, Militant Media offers a wide range of practice-based projects that have developed oppositional modes of representation and created new aesthetic strategies and tools.
