International relations refers to the study of how different countries interact with each other. It examines governance, governmental institutions and societies from a global perspective, exploring how countries might mediate global problems that affect more than one nation.(See disclaimer 1) International relations considers that global changes and outcomes are affected by the way in which different societies work either together or in opposition to each other.(See disclaimer 2)

International Relations Definition

What is international relations? International relations is a broad field that encompasses many complex topics in diplomacy, foreign policy, war and peace, international law, global justice and the interdependence of globalization. It explores how countries cooperate and work together to avoid conflict and promote mutual interests, as well as how diplomacy fails and conflict erupts. Essentially, it’s the study of the many factors that shape power and conflict on a global scale.(See disclaimer 3)

Is international relations the same as diplomacy? Diplomacy is part of international relations. In fact, there is an argument to be made that diplomacy is the beating heart of international relations, as diplomacy can negotiate agreements, encourage collaboration to solve global challenges and avert conflict, whereas the lack of diplomacy can cause a breakdown in the global order and may start conflicts.(See disclaimer 1)

Diplomacy is the mechanism through which nations conduct negotiations and cultivate relations. It strives to open dialogue, nurture strong relationships and create a collaborative framework for nations to work together. In other words, diplomacy is essential for fostering goodwill and promoting international alliances, which help ensure peace and global stability.(See disclaimer 1)

Core Principles of International Relations

There are many core principles to consider when studying international relations. For example, the field emphasizes globalization and interdependence. No country exists in a complete vacuum; all nations are dependent on each other to some degree, thanks to their economic, cultural and political ties and shared global challenges. Globalization and interdependence can lead to more opportunities when nations cooperate, such as cultural exchanges and trade.(See disclaimer 4)

Other principles of international relations include:(See disclaimer 3,4)

  • Diplomacy and international negotiations: These are the primary ways in which different countries communicate, negotiate, create alliances and manage conflict.
  • International institutions: These organizations provide a framework for international cooperation, shared decision-making and multilateral agreements that promote mutual best interests (e.g., United Nations, World Trade Organization and World Health Organization).
  • National interests: These are a country’s goals within the context of an interconnected world.
  • Foreign policy: This is a government's strategy for managing relationships and interests with other countries.
  • Global justice: This is a combination of mechanisms and processes for securing human rights globally, with an emphasis on humanitarian intervention and refugees.
  • Humanitarian development: This is the use of international relations to address global crises.
  • Sovereignty: This is the right of each country to its own autonomy.
  • Global governance: This is the shared decision-making and management of challenges that transcend national borders.

How International Relations Works

Diplomacy and negotiations may be conducted through formal channels, such as at embassies and summits, or through back-channels, such as when two representatives of different countries meet informally to foster goodwill and cooperation.(See disclaimer 4)

Through respectful dialogue and established processes, nations may work together to address transnational problems, such as:(See disclaimer 2,3,4 )

  • Wars and the threat of war
  • Climate change and its effects
  • Threats to human rights
  • Digital warfare
  • Pandemics
  • Terrorism

By working together cooperatively, countries can improve global security. Some specific examples of how international relations theory might be applied include:

  • Representatives from multiple countries meet to discuss a proposed free trade agreement that aims to reduce obstacles to international commerce, such as tariffs. They reach agreements on everything from labor rights to intellectual property rules, and promote better trade amongst their countries.
  • Under threat of a new pandemic, representatives from different governments as well as from global institutions like the World Health Organization meet to facilitate the sharing of scientific data, coordination of travel restrictions and shared resources for developing a vaccine.

What Is an International Relations Major?

An international relations major is a student who studies the field of international relations, including the core principles of international relations. This can be an ideal major for individuals who are interested in promoting cooperation and solving global challenges. International relations is an interdisciplinary field that brings together elements of economics, law, history and politics.(See disclaimer 3)

An international relations major might study conflict resolution, diplomacy, cross-cultural communication and foreign policy. Some of the skills that might be promoted in this type of degree program include critical thinking, analytical reasoning, cultural competence, professional ethics and communication skills.(See disclaimer 3)

International Relations vs. International Studies

International relations and international studies aren’t the same. International relations focuses on global affairs and how different nations behave within a global context. It emphasizes how different countries interact with each other.(See disclaimer 5)

In contrast, the international studies field examines countries from a social and cultural perspective. It considers the cultural, anthropological and political factors that affect people in different societies.(See disclaimer 5)

Within the international relations field, there are many career paths to consider. For example, with a BA in Government with an Emphasis in Public Administration, you might pursue a career as a political scientist. Political scientists study different political systems, including how they develop and how they operate.

Other careers that may be related to international relations can include:(See disclaimer 3)

  • Policy analyst: Analyzes data and develops insights on issues like global trade and security
  • Humanitarian worker: Manages programs and delivers aid to communities in need
  • Risk consultant: Examines and analyzes global risk, compliance and markets to deliver insights to businesses
  • Institutional officer: Fulfills administrative, legal or policy functions within an international institution
