Europeanization has by now become the most used and fashionable term found in social sciences. The application of the concept and the model(s) of Europeanization are thus no longer restricted only to domestic changes in EU member-state countries they are also used to study any of the domestic changes in the potential EU member-state countries because of the impact resulting from the Enlargement process. The literature on the potential EU member-state countries has been dealing almost exclusively with Europeanization of then-CEEC candidate countries and not with the new potential EU member-states from the Western Balkans. The book, therefore, study Europeanization of the Western Balkans, addressing same research questions but this time employing new cases and the most appropriate still less used method of fuzzy set Qualitative Comparative Analysis (fsQCA), with a final aim of not only understanding the actual transformations that the region is going through as result of the enlargement process but also of contributing to a more general understanding of Europeanization in the potential EU member-state countries.
