This article explores the motivations of young party activists of Law and Justice (PiS) in Warsaw, focusing on the influence of party identification on their attitudes and political engagement. The author, using the qualitative method of in-depth individual interviews, conducted an exploratory analysis of the attitudes of eight members of the PiS Youth Forum aged 20 to 25. The study is framed within the theoretical perspectives of political socialization, polarization, party identification, and typologies of political motivation — policy-seeking versus office-seeking. The results show that young activists exhibit a strong affective bond with the party, rooted in family political socialization and an ideological community based on patriotism, catholicism, and social solidarity. The study contributes to the sociology of politics by highlighting a significant observation regarding the paradox of PiS’s urban electorate, which, despite its structural demographic misalignment, demonstrates a lasting and strong emotional-ideological attachment to a party with a distinctly populist character, thereby reinforcing the PiS vs. anti-PiS polarization.
