The international system has experienced significant transformation since the end of the Cold War. For nearly three decades, the world functioned largely under a unipolar structure led by the United States. However, by the 2020s, power began to redistribute among multiple actors — economic, military, and technological — marking the emergence of a multipolar world.
This article examines the structural evolution from unipolarity to multipolarity. It analyzes the economic, political, and strategic dimensions that define this transition and explores how emerging powers, regional organizations, and technological developments are reshaping the foundations of the global order.
2. Understanding Polarity in International Relations
2.1 Definition of Polarity
- Polarity refers to the distribution of power among major states in the international system.
- It determines how influence and decision-making authority are organized globally.
- Systems are often categorized as unipolar, bipolar, or multipolar based on power concentration.
2.2 Unipolarity Explained
- A unipolar world exists when one state holds dominant capabilities in military, economic, and political dimensions.
- The unipolar power sets norms, leads global institutions, and manages collective security.
- The United States occupied this position after the Cold War, influencing international rules and markets.
2.3 Multipolarity Explained
- A multipolar system consists of several major powers with comparable influence.
- Decision-making becomes decentralized, with alliances shifting based on interests.
- Multipolarity can increase flexibility but also introduces competition and uncertainty.
