The European Union (EU) is a supranational political system that unites more than twenty-five European countries. European integration began to facilitate economic cooperation. Over time, it evolved into both an economic and political union. The progress in European integration accelerated in the 1980s and the 1990s. As a result, the European Union was established in 1993 and assumed more political power. The process of establishing the European Union was slowed by the results of a referendum in Denmark, which at first did not approve the treaty establishing the EU. This referendum made it clear that public support for European integration could no longer be taken for granted and that public attitudes toward the EU are crucial for the European Union’s future development. In other words, the era of permissive consensus ended and it became clear that public opinion has become a powerful force in the development of European integration. Since then, public opinion has had a clear influence on the direction of European integration in a number of ways. Examples of this influence include the rejection of the single European currency in Sweden, the failure of the Constitution for Europe, and, most notably, the United Kingdom’s decision to exit the EU. Public opinion has influenced European politics in other ways as well. For example, national political elites, acting at the European level, are constrained in their decisions by public opinion at home. The importance of understanding public opinion toward the EU has given rise to a lively research program. In their quest to understand citizens’ attitudes toward the EU, researchers first had to conceptualize the key concepts in this field, in particular the meaning of public support for the EU. Following this, scholars began to investigate why people support or oppose the European Union, which became the most widely studied topic in this field. In addition, studies have examined public support for specific European policies, determinants of voting in EU-related referendums, public support for EU membership in countries outside the EU, and the extent to which public opinion matters for policymaking in the EU. All these topics are included in this annotated bibliography. The section devoted to General Introductions and Review Articles lists review articles and textbook chapters that provide a quick overview of the topic as a whole. The next section, What Is Public Support for the EU and How Do We Explain It?, digs deeper into the concept of public support for the EU, asking how the concept is defined and what explains support for the EU. The following three sections deal with public opinion toward specific EU policies (Public Opinion toward Specific EU Policies), public support for the EU in nonmember states (Public Support for the EU in Candidate Countries and Other Nonmember States), and the question of public opinion’s influence on policymaking in the EU (Does Public Opinion Matter for Policymaking in the EU?). The second-to-last section is devoted to referendums on European matters (Referendums: Explaining the People’s Vote, Explaining Brexit). The last section (Data Sources) looks at data sources that can be used in the study of public attitudes toward the EU.
