A longstanding scholarly debate asks what lasting changes revolution makes in political attitudes and behaviors. Scholars generally regard revolution as transformative, but research on revolution's behavioral and cultural legacies after transfers of state power has been limited. This study explores revolution's residual impact on individuals' electoral participation, civil society engagement, and social capital by comparing postrevolutionary Nicaraguans to their Central American neighbors. Using survey data on comparable samples of urban Central Americans, the research found higher electoral engagement in Nicaragua than in the other nations in the region that experienced major insurgencies but not revolution. It also found among Nicaraguans greater support for civil disobedience, greater school and union activism, and more frequent leftist political identification. Although revolution did leave residual effects in Nicaragua, more significant influence appears to have decayed rapidly.
