The articles in this special issue are drawn from papers presented at a conference titled Critical Terrorism Studies: Practice, Limits and Experience. The conference was organised by the Critical Studies on Terrorism Working Group of the British International Studies Association (BISA). The event was supported by both a BISA workshop grant and by Loughborough University’s Centre for the Study of International Governance (CSIG) and was held at Loughborough University from 9–10 September 2013. The conference aimed to explore what we know about terrorism and counterterrorism and importantly to ask how we know it. Reflecting the recent “materialist”, “everyday”, “experiential” and “narrative” turns in the fields of International Relations (IR), Geography and Cultural Theory, the event brought together scholars and practitioners to reflect on practices of research and knowledge production in Critical Terrorism Studies and related fields. The articles in this special issue reflect those aims.
