Hedley Bull

Hedley Bull is the IR scholar who argued that even in anarchy, states form an international society through shared rules, sovereignty, and institutions. In Intro to International Relations, his ideas help explain how order exists without a world government.

What is Hedley Bull?

Hedley Bull is a major international relations theorist best known for arguing that the world is anarchic, but not chaotic. In Intro to International Relations, his name usually points to the idea that states do not just compete for power, they also create a kind of order by following shared rules, recognizing sovereignty, and using institutions.

His best-known book, The Anarchical Society, makes a simple but useful claim: anarchy means there is no higher government above states, yet states still behave as if they belong to a society. They do this because they expect each other to respect borders, diplomacy, treaties, and basic rules of coexistence. That is what Bull means by international society.

This is a useful middle ground between pure realism and more optimistic views of cooperation. Bull does not say states are friendly or equal, and he does not assume they are always driven by morality. He still takes conflict, balance of power, and rivalry seriously. But he also says order is maintained through norms and institutions, not just military force.

Bull also separated international order from world order. International order refers to stability among states, like when borders are respected and war is limited. World order is broader, including justice, human welfare, and economic stability. A state system can be orderly without being fair, which is why Bull is so useful for analyzing tensions between stability and justice.

In a class discussion, you might use Bull to explain why the United Nations, diplomacy, arms control, or diplomatic protocol matter even when no world government exists. His work helps you see that global politics is not just a raw power struggle, it is also a rules-based system that states constantly reproduce, stretch, and defend.

Why Hedley Bull matters in Intro to International Relations

Hedley Bull matters because his ideas show up in a lot of the core debates in Intro to International Relations: Can states cooperate under anarchy? What makes sovereignty matter? Why do institutions sometimes constrain powerful countries? Bull gives you language for explaining why global politics has both conflict and order at the same time.

He is especially useful when you are comparing theories. Realism often focuses on power and survival, while constructivist readings focus on norms and shared meanings. Bull sits in a space where both of those things matter. That makes him a strong tool for essays that ask you to explain why states follow rules even when they could break them.

His distinction between international order and world order also gives you a sharper way to write about current events. A region might be stable in the short term, but still unjust or unequal. Bull helps you separate those two questions instead of treating them as the same thing.

How Hedley Bull connects across the course

International Society

This is Bull's main idea for explaining order under anarchy. States may not answer to a world government, but they still act like members of a society with shared rules, diplomatic practices, and expectations. When you see states respecting sovereignty, signing treaties, or recognizing one another, you are seeing international society in action.

Balance of Power

Bull treats balance of power as one of the main ways order gets preserved in an anarchic system. States check each other so that no single power dominates completely. In essays, this term often works alongside Bull because it shows the power side of order, while international society shows the rule-based side.

Anarchy

Bull starts from anarchy, but he does not treat it as total disorder. In IR, anarchy means no higher authority sits above states, not that anything can happen at any time. Bull's contribution is to show how states build norms and institutions precisely because there is no central government.

Kenneth Waltz

Waltz and Bull are often read together because both take anarchy seriously, but they emphasize different things. Waltz is more structural and focused on how the system pressures states, while Bull gives more attention to rules, institutions, and shared expectations. Comparing them helps you explain whether order comes mainly from structure or from society.

Is Hedley Bull on the Intro to International Relations exam?

A short-answer question or essay prompt may ask you to explain how order exists in an anarchic international system. That is where Bull fits: you would name him, then use ideas like sovereignty, diplomacy, and international society to show how states create rules without a world government.

In a passage analysis, you might identify Bull when a text says states are self-interested but still bound by norms and institutions. If the prompt contrasts power politics with shared rules, Bull is usually the theorist you want. In a case study, you could apply him to the UN, treaty systems, or postwar diplomacy and explain why states cooperate even when they remain rivals.

Key things to remember about Hedley Bull

• Hedley Bull argued that anarchy does not eliminate order in world politics.

• His big idea is international society, meaning states act within shared rules, norms, and institutions.

• He distinguished between international order, which is stability among states, and world order, which includes justice and human welfare.

• Bull is useful when you need to explain why sovereignty, diplomacy, and treaties matter even without a world government.

• His work sits between realism and constructivism, so it is great for comparing power, norms, and institutions.

Frequently asked questions about Hedley Bull

What is Hedley Bull in Intro to International Relations?

Hedley Bull is an IR theorist known for the idea that states can create order even in an anarchic system. He argued that shared norms, sovereignty, and institutions form an international society. In Intro to International Relations, he is often used to explain why global politics is structured, not purely chaotic.

What did Hedley Bull mean by international society?

International society is Bull's term for the set of shared rules and expectations that states develop when they interact with one another. It includes diplomacy, treaty-making, sovereignty, and other practices that make state behavior more predictable. The point is not that states stop competing, but that they still recognize common standards.

How is Hedley Bull different from Kenneth Waltz?

Both scholars take anarchy seriously, but they focus on different parts of the system. Waltz is more focused on how the structure of anarchy pushes states to behave in certain ways, while Bull pays more attention to rules, institutions, and shared norms. If a prompt asks about order through society rather than structure alone, Bull is the better fit.

Why does Hedley Bull matter for global governance?

Bull helps explain why global governance can exist without a world state. Organizations, treaties, and diplomatic norms work because states accept certain rules, even when they disagree. His ideas are especially useful for discussing the tension between state sovereignty and international cooperation.
