In this article I examine Rokkan-Urwin centre-periphery model, which is used to analysis of interstate relations. This model, developed in the 70s has been used to describe and explain interregional differences and inequalities. Point of departure of Rokkan and Urwin was the analysis of regional potential. Final aim was to focus on political mobilization in different regions in the context of the local policies. My paper changes the level of analysis into interstate relations. My aim is to identify the processes of peripheralization of regions and states in Europe and to answer the question of ability to overcome peripheral status in the international system.
