How can conflicts between various nationalist/ethnic groups be reduced? Combining theory with case studies of Spain and Ireland. Neal G. Jesse and Kristen P. Williams develop an argument favoring a solution that links resolving issues of identity and preceptions of inequality to the extablishment of cross-national, democratic institutions. These institutions can affect deeply held attitudes by promoting overlapping identities and pooling sovereignty. Overlapping identities reduce tension by creating an atmosphere where different ethinic groups lose their strict definitions of Self and Other. Pooling sovereignty across a number of international (and natinal) representative bodies leads to increased access to governmental policymaking for all parties involved, with each nationalist/ethnic group having a stake in government. Increased access, moreover, reduces threat perceptions and ethnic security dilemmas, and increases trust--"all of which play an important role in overcoming such conflicts.
