What is the political legacy of violent conflict? I present evidence for a link from past violence to increased political engagement among ex-combatants. The evidence comes from northern Uganda, where rebel recruitment generated quasi-experimental variation in who was conscripted by abduction. Survey data suggest that abduction leads to substantial increases in voting and community leadership, largely due to elevated levels of violence witnessed. Meanwhile, abduction and violence do not appear to affect non-political participation. These patterns are not easily explained by conventional theories of participation, including mobilization by elites, differential costs, and altruistic preferences. Qualitative interviews suggest that violence may lead to personal growth and political activation, a possibility supported by psychological research on the positive effects of traumatic events. While the generalizability of these results requires more evidence to judge, the findings challenge our understanding of political behavior and point to important new avenues of research.
