Multilevel governance (MLG) as a research approach has mostly been applied to explain governance issues surrounding the European Union or international organizations. As a general research framework in the area of international relations (IR) theory, however, MLG has widely been underutilized, despite the many advantages that the approach offers in the empirical investigation of an increasingly complex international or global system. There are key concepts, assumptions, and definitions of MLG that focus separately on levels and governance as key elements of the approach and its interdisciplinary lineage. Some contested IR concepts include sovereignty, the nation-state, the international system, anarchy, agency, and levels of analysis. These IR concepts benefit from the application of an MLG framework by enabling the use of an interdisciplinary and multimethodological, yet systematically comprehensive, approach—which allows for nuanced use of these concepts. Other areas that benefit from IR methodologies applied in MLG research are methodological toolkits with a special focus on the areas of global governance, security studies, and international political economy.

Over the course of more than four decades the International Crisis Behavior (ICB) Project, a major and ongoing data-gathering enterprise in the social sciences, has compiled data that continues to be accessed heavily in scholarship on conflict processes. ICB holdings consist of full-length qualitative case studies, along with an expanding range of quantitative data sets. Founded in 1975, the ICB Project is among the most visible and influential within the discipline of International Relations (IR). A wide range of studies based either primarily or in part on the ICB’s concepts and data have accumulated and cover subjects that include the causes, processes, and consequences of crises. The breadth of ICB’s contribution has expanded over time to go beyond a purely state-centric approach to include crisis-related activities of transnational actors across a range of categories. ICB also offers depth through, for example, potential resolution of contemporary debates about mediation in crises on the basis of nuanced findings about long- versus short-term impact with regard to conflict resolution.
