Polycrisis and the Transformation of International Order: A Systemic Complexity Framework

Abstract

This article analyzes issues surrounding the polycrisis and the transformation of the international order through the lens of systemic complexity. The growing intertwining of geopolitical rivalry, economic shocks, technological competition, climate change, health crises, and resource security challenges has fundamentally altered the nature of contemporary international politics. These crises do not merely unfold in isolation; they increasingly reinforce one another, generating cascading effects and systemic vulnerabilities that challenge traditional conceptions of the international order. While existing international relations theories offer insight into specific aspects of instability, they often fail to explain the mechanisms of interaction between simultaneous crises and their broader consequences. This article develops a conceptual model based on the principle of systemic complexity to explain how the polycrisis drives the transformation of the international order. Drawing on complexity theory and systems thinking, the authors conceptualize the international order as a complex adaptive system comprising multiple actors operating across closely interconnected domains: security, the economy, technology, the environment, and public health. Through mechanisms of interdependence, spillover effects, feedback loops, and adaptive responses, the polycrisis generates non-linear dynamics that reshape patterns of cooperation, competition, and governance. Based on qualitative conceptual analysis and illustrative examples, the article argues that the polycrisis constitutes a systemic state rather than a mere temporary accumulation of disparate shocks. The proposed approach offers a complexity-theory perspective on contemporary global transformations and provides a foundation for further research into the evolving architecture of the international order.
