The main objective of the book is a multi-aspect analysis of the functioning of the Kaliningrad Region in contemporary political reality, both in internal and international dimensions. The area constitutes a unique enclave in contemporary Europe, being the only part of Russia separated from the mother country, which determines the taking place therein in the dimension of relations: bilateral, multilateral (e.g. EU - Russia, NATO - Russia, Baltic Sea Region cooperation) as well as regional and local cooperation. The book is a result of many years' work of scientists from Poland, Russia and Sweden, who have been researching the functioning of the Kaliningrad Region in internal and external dimensions.
