What is the record of right-wing terrorism and violence (RTV) in Western Europe since 1990? Why have some countries experienced more RTV than others? And why do some right-wing activists resort to violence while the large majority remains non-violent? This paper addresses these questions by introducing key findings from a new and unique dataset covering more than 450 RTV-incidents in Western Europe after 1990. Each incident is coded on a range of variables, including perpetrator characteristics, targeting, weapons, casualties, and type of violence. These data will be combined with time-series data on right-wing violence from eight West European countries to explore hypotheses about the conditions under which different types of RTV emerge.
