This chapter examines France’s relationship with the European Union by focusing on the heterogeneity of adaptation to the EU. While public policy and legislation became increasingly Europeanized, the EU had a limited impact on political life and the domestic institutional system. This situation changed during the 2010s, as revealed by the 2017 presidential elections and the arrival of President Macron. The chapter considers patterns in France–EU relations before discussing the impact of EU membership on public opinion and political parties. It then looks at the Europeanization of French politics and the impact of EU membership on French institutions as well as public policy. The chapter argues that while domestic politicization is recent, there remains considerable continuity in other aspects of France’s adaptation to the EU.
