The EU has led to a strong diversity of governance modes in political practice – followed by an equally rich literature on the topic. The so-called “governance turn” in EU studies testifies to these developments, which led to an increase in scholarly interest in regard to old but especially to new modes of governance (NMGs). While supranational governance is certainly the most prominent addition to the “toolkit” of governance that can be attributed to European integration, many other modes of governance have emerged over the more than six decades since the European Coal and Steel Community (ECSC) was founded in 1951. The chapter presents the key empirical variants of governance in current EU policy-making and shows how they have evolved over time. Then it sheds light on up to date research questions and concludes with a reflection on gaps in the research on EU and supranational governance.
