The investigation can be seen as an inductive, empirical and more theory building study within the field of autonomy. First, it highlights the mapping of territorial autonomies in the world. Second, it shows how "good practice" of fuzzy-set QCA should be used within comparative research with not so small N. The study answers the questions of what conditions that explain the occurrence of territorial autonomy and what kind of different degrees of autonomy that exist within the group af territorial autonomies as such. These questions are answered through a stepwise application of using fuzzy-set QCA as the methodological technique. First, an application of necessary conditions is conducted only with the set of territorial autonomies in hand. Second, an elaboration of sufficient conditions is outlines with both the set of territorial autonomies and set of non-autonomous entities as a control group.
