The book analyses state of play regarding regional level of government in the countries of South East Europe, particularly countries succeeding former Yugoslavia (Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Kosovo, and North Macedonia) using the research methods from the fields of Law, Public Administration and Political Science. The book offers fresh analytical perspective of the regional self-government issues in these countries, out of which every country has particular issues to deal with. Be it controversial territorial restructuring debate (Croatia), complex institutional system (B&H), dealing with territorial concentrated ethnic minorities (Serbia, Kosovo, North Macedonia) or the issue of small size and non/existence of regional forces (Slovenia, Montenegro). Besides the introductory (methodological) and concluding (synthesis, trends and issues for further research) chapters, the book contains country chapters written by experts from a particular country in the region who follow the same chapter structure which allows further comparisons. Besides that, the book contains three chapters on several cross-cutting issues such as position of ethnic minorities and their territorial (regional) concentration and institutional representation in the overall system of local and regional self-government, analysis of regional political parties and movements that influence the debate in these countries, and the analysis of position and interplay of decontenrated state administration and regional self-government in analysed countries.
