The study recapitulates the basic outlines of 1968 and reconstructs the relationship of individual streams within Czech society to the reform activities of that time on the basis of historical sources. Similarly, changing attitudes are observed during the period of so-called "normalization" and in the phase of gradual changes in the 1980s. The third part of the study is devoted to the creation of attitudes to 1968 in Czech society after the fall of the communist system in 1989, ie in the environment of democracy and market economy.
