Europeanization refers to the mutual influence of the European Union (EU) and its member states, to interactions within and between member states driven by the EU, and to the effect of the EU on EU applicant states. It affects domestic politics, policy, and polity and therefore is relevant for citizens and businesses. Europeanization effects also raise an issue of legitimacy: who bears responsibility, the member states or the European Union?
In the broadest sense, analysis of Europeanization began with the theories of regional integration in the 1950s, which explained what was to become the early 21st-century EU and how it began and developed—the making of a polity. In the narrow and more common use of the concept, studies of the effect of what was then known as the European Community began at the end of the 1980s and the beginning of the 1990s under the name of “adaptation.” It was not until 1994 that Robert Ladrech used and defined the term “Europeanization” for analyzing the effect of the European Community on its member states. Thus, in its most encompassing sense, a complete typology of Europeanization includes five types, each with its own primary mechanisms at work: (a) meta-Europeanization, the processes whereby the member states that have created the EU have set the overall frame, that is, the EU; (b) downloading, which implies a pressure on EU member states’ policies and governmental structures to adapt to EU standards (but this does not lead to “uniformity,” as the member states have diverse histories and traditions); (c) uploading, whereby the member states contribute to the EU’s further development by making policy suggestions to the EU and its institutions; (d) cross-loading, whereby the EU creates frames for the member states to exchange best practices and experiences, with little or no involvement from the institutions; and (e) export Europeanization, whereby the EU makes potential members comply with the Union. In a narrow sense, Europeanization is about downloading, uploading, and cross-loading.
Studies on Europeanization have contributed greatly to our understanding of how the EU works and how it influences its member states and vice versa (not to mention its influence on subnational actors as well as on interest organizations and neighboring countries). In the early 21st century, Europeanization studies expanded to policies that were previously not sufficiently considered: for instance, the Common Foreign and Security Policy, the Common Security and Defence Policy, and social movements.
