Abstract
Since the end of the communist era in the early 90's, new countries have emerged. These countries had to rebuild a political system, which had often been based on the model given by the Western Europe countries. However, these new democracies remain unstable and complex. Indeed, democratization is a young process for these countries and it is described as a period of instability and transition. However, we can consider that this is more a phase of reorganization and adjustment. I will try to show that the comparison made between the stable political systems of Western Europe and those of the post-communist Europe is difficult: first because of the historical point of view, second because of a societal point of view. Finally, we can ask if stability would be possible through other models.
