The Loser’s Long Curse: How Exposure to Class Conflict Shapes Election Outcomes

Understanding the political consequences of civil war exposure is a challenging task, given the myriad of overlapping and at times divergent mechanisms involved. This article provides evidence of the persistent political legacy stemming from exposure to a violent class conflict. We revisit the Finnish Civil War of 1918 and first trace out the impact of local conflict exposure on electoral outcomes over a quarter-century period between the World Wars. To do so, we combine a difference-in-differences approach with historical data on the geographical distribution of civil war casualties and election outcomes. We document that the local electoral performance of left-wing parties that were associated with the insurgents was persistently and negatively affected by civil war casualties on both sides of the conflict. We also discuss potential mechanisms behind this finding and further show that the civil war had an enduring impact on the Finnish political landscape over a hundred years.
