The fall of the Communist regimes in the countries of Eastern Europe and the Soviet Union, and their commitment to social, political and economic reform, represent two aspects of a deep process of social transformation. As in all socio-political transformation which overturns the previous political and economic order, this process needed to develop an ideology and a concrete image of the future in order to mobilize their populations, to invent that certain political rationality which is indispensable for bringing reform to a successful conclusion, and to produce a certain coherence in the changes which occurred in the various fields of life in society. Unlike the preceding revolutions which had gradually nourished hopes for a better life and had expanded the horizons of human possibility with difficulty, movements towards democracy in the former Communist countries found an almost ready-made model.
