This graduate thesis deals with the determinants of political trust and political participation of young people as a social group that is considered to be politically marginalized and insufficiently involved in decision-making on important topics. The paper is based on a research conducted at the Catholic University of Croatia (HKS), on a sample of 253 male and female students. The sample was stratified on the basis of gender and age of the respondents and place of residence, ie the size of the place with regard to the number of inhabitants. The main research hypotheses stem from previous research on political trust and political participation, in which the main assumption is that young people are not sufficiently involved in politics, that they can not express themselves from older politicians and that they are not ready to give more, although they want to change the current political situation. The aim of the thesis was to examine how politically active HKS students are, in which organizations they are more often involved, whether they think that young people are sufficiently involved in politics or not, and the reasons for such an opinion. At the very end, respondents were offered an open-ended question to write their opinion on all questions in the research. The analysis of the results confirmed the hypotheses and showed that the students of the Catholic University of Croatia do not differ too much from their peers who participated in other research on the same topic in Croatia and Europe.
