East-Central Europe can be easily distinguished, despite diff erent views on the subject, as a geographical space. It cannot be said, however, that it constitutes a distinct and coherent political, economic, social, and cultural space. Changes taking place in contemporary Europe, in particular those associated with the integration processes, mark a new, specifi c dividing line, different from that during the Cold War. It runs across the geographical, and, consequently, social, political, economic and cultural space of East-Central Europe. Th e research objective is therefore to identify and analyze the “fracture” of social space in this part of Europe. For research purposes it is assumed that social space, denoting the whole of social behaviors and ties as well as material products of human activity, is a complex, multifaceted construction. Especially signifi cant seems to be the problem of the political empowerments of society and its limitations, the problem of the socio-economic situation, and the problem of cultural identity. It is also assumed that the EU’s political strategy currently being pursued, consisting in relinquishing the prospect of EU enlargement towards the east to include selected countries of the so-called post-Soviet area, contributes to strengthening “the fracture” of East-Central Europe. Th is is apparently the result of the European Union’s implementation of “A Europe of Projects” strategy, which is the measures undertaken under the European Neighbourhood Policy, Eastern Partnership, or Back Sea Synergy.
