Replication data for: Ethnicity matters: Transnational Ethnic Alliances and Foreign Policy Behavior.

This article investigates the influence of transnational ethnic alliances on the international interactions of states. Transnational ethnic alliances exist when both states in a dyad contain members of the same ethnic group. We argue that two types of dyads will experience higher levels of conflict than other dyads: (1) those where an advantaged minority in state A has an ethnic tie to a nonadvantaged minority in state B, and (2) those with a transnational ethnic alliance where the group in one of the states is politically mobilized. Using data from the COPDAB, Minorities at Risk, Polity 11, COW, and Penn World Tables projects we find support for these contentions
