State-led repression of minority identities is a well-documented phenomenon, yet its implications for national identity remain understudied. We examine how the Soviet state-induced famine (1932–33) shapes contemporary Ukrainian national identity through vertical (familial) and horizontal (community/state) transmission. Using newly geocoded individual-level data, we find that individuals from high-famine-exposure areas are more likely to identify as Ukrainian. We document that under Soviet rule, family networks preserved identity, while church closures weakened community transmission. After independence, state-led remembrance efforts, revitalized horizontal transmission. Our findings show how repression and remembrance shape identity persistence and reflect the famine’s lasting influence on Ukrainian-Russian relations.
