The purpose of this status report is to create an overview of the challenges related to right-wing and left-wing extremism in Denmark. The report will form part of a more comprehensive mapping launched partly with a view to concretising and targeting the preventive effort. The present report is based on existing and ongoing research in the area. It is a concrete and fact-based report which aims to identify where in present-day Denmark extreme political problems exist – and what kind of issues the Danish society is facing as a result of this. The report is not a mapping or an exhaustive account of the right-wing and left-wing extremist environments, but rather an attempt to establish a knowledge base which may serve as a foundation for such an investigation. Thus, the report reflects existing research on political extremism in Denmark, which is still relatively limited in scope. Consequently, the report also reflects the researcher‟s own observations and analyses of current developments in political extremism. Furthermore, the future mapping will be based on a quantitative investigation.
