The Europeanization of European Union (EU) member states seeks their econom
ic and political integration, if not eventual federal union, within a commo
n market. EU programs and policies have done much to inject capital into No
rthern Ireland, but little to weaken the hold of nation and state in local
political culture. In fact, in the borderlands of Northern Ireland the boun
daries between nations and states are more important than any metaphorical
"Europe without frontiers." This essay examines a European policy program,
INTERREG, which has enjoyed only partial success at the Northern Ireland bo
rder, in order to delineate some of the obstacles to the cross-border coope
ration which is its goal. It also relates these obstacles to flaws in natio
nal and European policy making and implementation to inform wider research
both in the anthropology of the EU and in the anthropology of international
borders.
