The explosion of cities and megacities has increased scholars’ and policy markers’ attention to the effects such changes might have on conflict: increasingly, urban environments may alter the nature of warfare but not necessarily the incidence of intrastate war. We argue that high levels of urban concentration—the concentration of populations in one or relatively few urban centers—increases both the likelihood of civil wars and their intensity. Urban concentration limits the ability of the state to project power across space, exacerbating grievances in rural areas, easing rebel control of territory, and enhancing their military strength. At the same time, cities become high-value loci of contestation even as urban warfare constrains conventional state military strength. The result is more symmetrical fighting producing more battle deaths. Cross-national regressions show that urban concentration exerts a crucial effect on the likelihood, nature, and intensity of intrastate warfare.
