Abstract: Even in the weakest, most war-torn states, remarkably peaceful regions exist. We posit that the emergence of regions with comparatively high levels of security depends on the presence of bounded rulers. Bounded rulers hail from a dominant local group that is a minority at the national level, which bounds their political careers within a given region. Because of their limited upward mobility, they govern with a long time horizon and can guarantee protection to their population in return for information and support for the regional government. To test this theory, we leverage interviews with local elites in Afghanistan, Iraq, and Somalia; an original data set on governors in these countries; and a difference-in-differences estimation. The evidence supports our theory: bounded rulers significantly reduce local violence during their tenures. The findings suggest that donors could use targeted aid to support regional solutions to insecurity in fragile states.
