In Germany, interpretations of the epochal year 1968 range from its being a second founding of West-German democracy to the epitome of leftist fascism. In the Czech Republic, on the other hand, this year marks a clear break in history: The invasion of tanks from the Warsaw Pact into Prague represents a clear fissure of the Golden 60's and Prague Spring from the following time of normalization - which for some two million Czecks and Slovaks meant direct repressions. The authors pursue the question whether above and beyond that there were phenomena such as a protest culture and new systems of symbols that transcended the borders of individual countries; whether there were common causes that breached the time between 1968 and 1989. Especially important is the question of how this time period is depicted in the learning materials of the respective countries. German text.
