Abstract
This article investigates the lasting impact of historical-political tragedies on
current political behavior, focusing on Chile’s Estallido Social protests (2019-
2020) and the Constituent Plebiscite (2020-2023). Using social media data to
analyze political memory, the study suggests that protests serve as a strategic
engagement tool in municipalities with vivid recollections of past violence from
the Pinochet dictatorship. Least squares analyses show that municipalities with
pre-1970 military bases had heightened protest activity but reduced constitutional voting involvement, without a clear political coalition bias. The 2SLS
estimations link this to the long-term effects of political victimization during
Pinochet’s regime and social media remembrance of the 1973 coup violence.
The evidence suggests that while collective memories of political violence may
encourage active protest participation, they can also weaken the relationship
between voters and political elites, influencing voting behavior
