Theories of International Relations: A Beginner’s Guide

Have you ever wondered why some countries form alliances while others engage in conflicts? Or why do global institutions like the United Nations influence world politics?

If you have, then you’ve already begun exploring the fascinating field of International Relations (IR). Today, we are diving into the Theories of International Relations, the guiding frameworks that help us understand how nations interact on the global stage.

Imagine you are playing a strategic board game with different players, each with unique goals, strategies, and resources. Some players form alliances, some seek dominance, while others prioritize trade and diplomacy.

Just like this game, the world of international politics operates under different principles, and IR theories help us make sense of these dynamics.

Understanding the Theories of International Relations

Theories of International Relations provide structured explanations for global events, diplomatic relationships, and power dynamics. Scholars and policymakers use these theories to analyze conflicts, trade relations, international organizations, and global cooperation (Waltz, 1979).

Broadly, these theories are categorized into three major schools of thought:

1. Realism
2. Liberalism
3. Constructivism

Each theory offers a unique lens to examine international affairs and understanding them can help us better interpret global politics.

Realism: The Struggle for Power

Think about a historical empire expanding its territory through conquests. This expansion reflects the core idea of Realism, which argues that international relations are driven by power and self-interest (Morgenthau, 1948).

Key Principles of Realism

• The international system is anarchic: There is no central authority to enforce rules.
• States are the primary actors: Governments prioritize their national interest and survival.
• Power determines relations: Stronger nations dominate weaker ones to maintain security and influence.

Example of Realism in Action

The Cold War (1947-1991) between the United States and the Soviet Union is a classic example. Both superpowers sought to maximize their military and political influence, fearing that the other would gain dominance (Mearsheimer, 2001).

Realism explains why nations invest heavily in defense and form military alliances like NATO to secure their interests.

Liberalism: Cooperation Over Conflict

Now, imagine a world where countries cooperate for mutual benefit. This is the essence of Liberalism, which believes that states can work together through diplomacy, international institutions, and economic interdependence (Keohane & Nye, 1977).

Key Principles of Liberalism

• International cooperation is possible: Organizations like the United Nations promote peace and stability.
• Economic interdependence reduces conflicts: Trade relations encourage peaceful coexistence.
• Democratic governments foster peace: Democracies are less likely to go to war with each other (Doyle, 1986).

Example of Liberalism in Action

The formation of the European Union (EU) demonstrates liberalism in practice. After World War II, European nations decided to integrate their economies and establish political cooperation, reducing the chances of future conflicts.

Liberalism explains why diplomatic negotiations, free trade agreements, and human rights advocacy play crucial roles in global governance.

Constructivism: The Power of Ideas and Identity

Now, think about how cultural beliefs and historical narratives shape a country’s foreign policy. Unlike Realism and Liberalism, Constructivism focuses on ideas, identity, and social norms as key drivers of international relations (Wendt, 1992).

Key Principles of Constructivism

• International relations are shaped by beliefs and identities: Nation’s act based on shared values and historical experiences.
• Social norms evolve over time: What is acceptable today might not be tomorrow.
• States construct their realities: Political ideologies and national identities influence foreign policy decisions.

Example of Constructivism in Action

Germany and Japan, once aggressive military powers in World War II, have redefined their national identities as advocates of peace and diplomacy. Their modern foreign policies are shaped by past experiences and societal expectations.

Constructivism explains why global norms on human rights, environmental protection, and nuclear disarmament continue to evolve.

Other Notable Theories of International Relations

Apart from the three main theories, scholars have proposed additional perspectives to understand international affairs:

1. Marxism

This theory examines the influence of economic structures and class struggles on international relations. It argues that capitalist nations exploit weaker states to maintain economic dominance. According to Marxist scholars like Immanuel Wallerstein (1974), global politics is shaped by a core-periphery system where wealthy nations benefit at the expense of poorer ones.

2. Feminism

Feminist IR theory highlights the underrepresentation of women in global decision-making and critiques the gendered nature of international relations. Scholars like Cynthia Enloe (1990) argue that traditional IR theories overlook the role of women in peacebuilding, war, and diplomacy. Feminism calls for more inclusive global governance.

3. Postcolonialism

This theory examines the lasting impact of colonial history on modern international relations. Thinkers like Edward Said (1978) argue that Western perspectives continue to dominate global politics, often marginalizing voices from the Global South. Postcolonialism seeks to challenge these power imbalances and promote decolonized narratives in international studies.

4. English School

The English School blends elements of realism and liberalism, focusing on the idea of an international society where states coexist through shared norms and institutions. Scholars like Hedley Bull (1977) suggest that while global politics is competitive, diplomatic customs and legal agreements create a degree of order.

5. Green Theory

Each of these theories offers a unique perspective, enriching our understanding of international affairs.

Conclusion

There is no single “correct” theory of international relations. Different perspectives offer different insights, and real-world events often combine elements from multiple theories.

Think about international relations as a puzzle—each theory provides a piece that helps complete the picture. Some events might align with Realism’s power struggle, while others showcase Liberalism’s cooperation or Constructivism’s emphasis on identity.

Next time you read about global conflicts, trade agreements, or diplomatic summits, try analyzing them through these theories. You’ll start to see patterns in international relations that were once invisible.
