Repression and the Spread of Ethnic Conflict in Kurdistan

Why do ethnic conflicts spread to neighboring states? This article examines the effect of transborder ethnic groups on the spread of ethnic conflict. It argues that when a transborder ethnic group is in conflict in one state, neighboring states perceive a threat from members of that ethnic group residing in their own territory, leading the state to take preemptive repressive action. This repression in turn changes the ethnic group's security situation within the state and can result in violence and thus ethnic conflict. Ethnic conflict spread is not determined by the actions of either the ethnic group or the state alone, but is a product of threat perception and interaction between the two groups. This argument is tested in a set of cases in a region where an ethnic conflict seems to have spread—the Kurds in Iran, Iraq, Syria and Turkey from 1961–2003.
