Can past wartime experiences affect political behavior beyond those who lived through them? We argue that local experiences of armed resistance leave political legacies that "memory entrepreneurs" can translate into contemporary political action via a community-based process of intergenerational transmission consisting of three core activities -- memorialization, localization, and mobilization. We empirically substantiate this argument in Italy, where an intense armed resistance movement against Nazi-Fascist forces took place in the 1940s. We combine statistical analysis of original data across Italian municipalities and within-case analysis of a purposively selected locality to show how the past impacts the present via the preservation and activation of collective memories. This study improves our understanding of the processes of long-term transmission, emphasizes armed resistance as a critical source of the long-term political legacies of war, and explores its political effects beyond electoral and party politics.
