This study examines the changes in Schwartz’s higher-order-value dimensions in Lithuanians over time. We analyze cross-sectional repeated survey data, with a sample of 11,199 respondents from six waves of the European Social Survey (ESS) during the years 2010–2020. Time-lag and cross-sectional analyses revealed age and period effects on self-enhancement and self-transcendence, and age, period, and cohort effects on openness to change and conservation. A comparison of political generations shows that the youngest cohort (independent EU generation) is more conservative, more self-transcending, less open to change, and less self-enhancing over time, in contrast to other generations. The Soviet legacy generations follow a different trajectory of openness to change and conservation than the Stalin and Independent EU generations, suggesting that historical context and current period effects are strong, and that the youngest political generation is particularly sensitive to societal-level disruptions. It is plausible that forces related to rapid societal change, for example, a decline in the working-age population after the collapse of the Soviet Union and, more recently, during the period of the study due to mass emigration, have left a generation trapped between scarcity and modernity.
