Drawing on research on political culture and research on geopolitical orientations, this article analyses public opinion in the three Baltic states (2014 and 2021), focusing on political support, inter-ethnic relations and geopolitical attitudes. In the first section, the empirical analysis demonstrates widespread public support for the national communities in Estonia, Latvia and Lithuania. Most respondents feel a sense of attachment to or pride in their respective homeland, and a relative majority of all respondents feel that their contemporary political systems are preferable to other systems in the past. At the same time, the analysis alert us to distinct ethnic differences: the Russian-speakers in the three countries tend to be decidedly more nostalgic about the Soviet past and less satisfied with the present regimes. Confirming and updating findings familiar from previous studies, this article also notes that the population groups in the three Baltic states were growing more or less accustomed to the domestic situation, up until the escalation of the Russo-Ukrainian war in 2022. In the second part of the article, we turn to geopolitical belonging and security perceptions in Estonia, Latvia and Lithuania.
