The countries of Central and Eastern Europe were singled out from the European context because of their cultural and historical background. These states, historically parts of empires, after the World Wars were located between the great powers and served as the watershed between the West and Eastern Europe, with which Soviet Russia was associated. After the collapse of the socialist system, and then the Soviet Union, the countries of Central and Eastern Europe were oriented toward European integration structures. Despite the queue for entry into the European Union, the dividing lines in Europe have not disappeared, which indicates the political nature of the processes on the continent, even though the need for cooperation to solve urgent European problems is high.
