This chapter examines the role of the EU in influencing Northern Ireland politics and the role of Northern Ireland in influencing EU approaches to ethnic conflict. The chapter is divided into three sections. In section one, an overview of EU policies is provided. In section two, the impact of the EU on political parties, business and public opinion in Northern Ireland is examined. In conclusion, the impact of Northern Ireland on the EU is examined. It is concluded that while the EU has played a role in Northern Ireland and in advancing cross-border cooperation, its role has been determined by British-Irish policy. Intergovernmentalism determines EU approaches. Northern Ireland is a model for the EU, but that model entails emphasis on state policies to resolve conflict – the EU responds to state demands in this realm, rather than playing an entrepreneurial role.
