The paper is aimed at investigating the main differences concerning the attitude towards politics of the two generations born in the 1920s and in the 1950s. They could be comprehensively represented by two events: World War 2 and the 1968 student mobilization. The former was a trauma which compelled everyone to make dramatic and contrasting choices. The latter was a restricted phenomenon which involved only an élite and produced long-run changes in demographic behavior (fewer and delayed marriages) as well as in human culture (environmental concerns).
Keywords: Politics, Generations, World War, 1968, student mobilization.
