This symposium emerged as a response to three recent developments in the field of terrorism studies. The first development has been the tremendous growth in terrorismrelated research and teaching activities since the attacks of 11 September 2001. Since then, terrorism studies has been transformed from a minor subfield of security studies to a large stand-alone field with its own dedicated journals, research centres, leading scholars and experts, research funding opportunities, conferences and university study programmes. As a consequence, it is now one of the fastest expanding areas of research in the Western academic world, with literally thousands of new books and articles published over the past few years, significant investment in terrorism-related research projects and increasing numbers of postgraduate dissertations and undergraduate students.
