Abstract: | The debate on the link between ethnicity and violence has been raging in political science literature since the end of the Cold War. Often, cross-country quantitative studies dismissed the importance of ethnic heterogeneity as a source of violent conflict. How the patterns of ethnic settlement within a country affect the severity of violence, though, has not yet been studied through similar techniques. In this essay, we build and analyse a data set of major violence-related variables collected at the local level during the 1992–1995 war in Bosnia-Herzegovina. What emerges is that the local distribution of the population, in terms of the number and relative size of the groups, is a key factor in explaining the intensity of violence in the Bosnian municipalities. |
