AbstractAdolescents support Eurosceptic and far‐right movements more and more. Since adolescents' years are a formative period for political orientations, it is important to promote a shared sense of belonging together among Europeans to counteract these tendencies. This could be achieved by fostering a European identity, however, only if its content is civically defined. We examined adolescents' understandings of being European, and how they relate to intolerance, EU support, and other predictors. Our sample included 1206 German adolescents (51% female, Age: M = 14.4, SD = .6, 27% ethnic minority adolescents). European identity was assessed via open answers and five closed questions. We conducted latent class analysis to identify identity classes. Three classes emerged: a living‐based (47%), a culture & value‐based (27%), and an ancestry‐based class (26%). Classes did not differ regarding EU support, but regarding intolerance (highest: ancestry‐based, lowest: culture & value‐based). Our results indicate that German adolescents differed in their understanding of being European and that it is important to consider how youth define Europeanness to understand European identity's effect on their views. Furthermore, our study argues for assessing identity openly to capture nuances of identity content adequately.
