Data collected in a survey of Greek college students were reanalyzed to compare personality, attitudes, and social class scores of students at colleges which did and did not instigate demonstrations and riots during the 1973 overthrow of the military dictatorship. Results indicate that at colleges where demonstrations occurred, males had higher needs for affiliation and lower needs for achievement and order than males at other colleges. Demonstrators indicated general dissatisfaction with many aspects of their university programs and came from higher social class backgrounds than students who did not demonstrate. Results are briefly compared with analyses of student demonstrators in the United States.
