Terrorism is increasingly a problem across Africa, but as yet little work has sought to investigate its political effects. Studies in Europe and the US suggest that terrorist attacks can increase social and political trust, improve satisfaction with government, and may raise turnout. But it is unclear whether we should expect these findings to hold in a context where political institutions are often fragile, and where political violence is frequent. We investigate this question in Nigeria, where terrorism has been widespread and increasing over the past decade.
