International Relations and the 19th Century Concert System

International relations (IR) scholars have long been fascinated by the politics of the European Concert of Great Powers—the diplomatic institution said to have provided relative peace, calm, and stability across Europe in the wake of the French Revolutionary and Napoleonic Wars. Interest in the Concert is boosted by arguments that the institutional and normative framework of the post-1815 European international order can serve as a useful template for managing great power relations in the increasingly multipolar and multicultural world of the 21st century. From this perspective, the ability of statesmen such as Metternich and Castlereagh to keep the European peace for almost 4 decades and provide pragmatic solutions to the most vexing international problems of revolution, dynastic rivalry, and national competition is meant to inspire contemporary world leaders to provide security and accommodation in the context of declining American hegemony and rising powers. The persistent centrality of the European Concert as a distinct subject area in IR scholarship raises a number of important questions: What exactly was the Concert and how long did it last? How did the Concert as an institution of great power management change over time? How do different theoretical approaches explain the ability of the Concert to structure interstate dynamics in meaningful ways? Most importantly, is it analytically feasible and normatively desirable to use the 19th century European Concert system as a blueprint for reorganizing international relations today? These questions identify key debates across the existing literature and demonstrate the conceptual, theoretical, methodological, and political diversity of the field. They also reveal that the formation of a disciplinary consensus on the Concert remains an elusive goal. As a result, scholars should remain attuned to ongoing historiographical developments and critically reflect on their own theoretical and political priors regarding the history and future of concert diplomacy.
