Rules in Global Politics

Introduction: Why do rules matter in a world without a world government? 🌍

students, imagine a football match with no referee, no written rulebook, and no agreed penalties. Teams could still play, but arguments would happen all the time, and the strongest players might simply ignore everyone else. Global politics can feel similar because there is no single world government with complete power over every country. Instead, states, international organizations, companies, and civil society groups interact through rules, agreements, and expectations.

In this lesson, you will learn how rules help organize global politics, why they matter even when they are not always enforced equally, and how they connect to power, sovereignty, legitimacy, and cooperation. By the end, you should be able to explain key terms, use examples, and show how rules shape the behavior of global actors in real situations.

Learning objectives

• Explain the main ideas and terminology behind rules in global politics.
• Apply IB Global Politics SL reasoning to examples of rules in practice.
• Connect rules to the broader study of power and global politics.
• Summarize how rules fit into understanding power and global politics.
• Use evidence and examples to support ideas about rules in global politics.

What are rules in global politics?

Rules in global politics are the agreed expectations, principles, laws, and standards that guide the behavior of actors in the international system. These rules may be written down, such as in treaties or the Charter of the United Nations, or they may be informal, such as diplomatic customs and shared norms. A rule tells actors what is allowed, expected, or prohibited.

It is helpful to separate three related ideas:

• Rules: specific instructions or standards for behavior.
• Norms: shared ideas about what is appropriate or acceptable.
• Laws: formal rules that are legally binding when states have accepted them.

For example, the rule against genocide is part of international law and also a strong global norm. The rule that ambassadors should be treated respectfully is a diplomatic norm and a long-standing practice. The rule that states should not use force against the territorial integrity of other states is found in international law, especially the UN system.

Rules matter because they create predictability. If students is trying to understand global politics, one useful question is: how do rules shape what powerful and less powerful actors can do? A country may have military strength, but it still faces legal and political limits. Another country may be weaker, but it can use rules to gain protection, challenge unfair actions, or build support from others.

Where do global rules come from?

Global rules are created in several ways. Some come from treaties, which are written agreements between states. A treaty becomes binding when states sign and ratify it according to their own legal processes. Examples include the Paris Agreement on climate change and the Convention on the Rights of the Child.

Other rules come from customary international law, which develops when states repeatedly act in a similar way because they believe they are legally required to do so. This is important because not every rule is written in a single document. Sometimes a pattern of state behavior becomes accepted as law over time.

Rules also come from international organizations. The United Nations, the World Trade Organization, the World Health Organization, and regional organizations like the European Union all help create, apply, or reinforce rules. Some organizations set standards for trade, health, or security. Others create forums where states negotiate and coordinate action.

Non-state actors also influence rules. Human rights groups, environmental organizations, businesses, and expert networks can push governments toward new standards. For example, campaigns by civil society helped place landmines and child labor under stronger international scrutiny. This shows that rules are not made only by governments in isolation.

How do rules relate to power, sovereignty, and legitimacy?

Rules are closely linked to power. Power is the ability to influence the behavior of others or shape outcomes. In global politics, powerful states often have more ability to make rules, interpret them, or avoid consequences when they break them. However, rules can also limit power by creating expectations and consequences.

This is where sovereignty becomes important. Sovereignty means that a state has authority over its own territory and population. At first glance, rules from international law might seem to threaten sovereignty because they place limits on state behavior. But sovereignty and rules are not opposites. States usually create rules through consent, meaning they agree to them in treaties or institutions. In this way, international rules can actually express sovereignty rather than destroy it.

Rules also support legitimacy, which means that authority is seen as right, fair, or acceptable. When states follow agreed rules, their actions often appear more legitimate. If a government acts outside accepted rules, it may face criticism, sanctions, or loss of trust. For example, if a state uses force without a lawful basis, other actors may question its legitimacy even if it has enough military power to act.

Think of legitimacy like trust in a classroom. A teacher who explains and follows clear rules is more likely to be seen as fair. In global politics, rules help build trust between states, especially when they disagree. Without trust, cooperation becomes harder.

Why do actors obey rules if there is no world police? 🚨

This is one of the most important questions in global politics. Since there is no single global government with complete enforcement power, why do states follow rules at all?

There are several reasons:

1. They want benefits. States follow rules because they gain trade access, security cooperation, or diplomatic recognition.
2. They fear punishment. Sanctions, isolation, or retaliatory actions may follow rule-breaking.
3. They care about reputation. A state that breaks rules too often may be seen as unreliable.
4. They believe in the rule. Some actors follow rules because they see them as morally or legally right.
5. They expect others to follow too. Rules work best when mutual compliance is common.

A real-world example is the use of sanctions by states or international organizations. If a state violates international rules, others may limit trade, freeze assets, or reduce cooperation. These are not always perfect punishments, but they can still affect behavior.

Another example is diplomacy. Even during tense conflicts, states often keep embassies open or respect diplomatic immunity because these rules help communication and reduce the risk of crisis. In this sense, rules are practical tools for stability as well as moral standards.

Examples of rules in global politics

International humanitarian law

International humanitarian law applies during armed conflict. It aims to protect civilians, prisoners of war, and those no longer taking part in fighting. Rules such as distinguishing between civilians and combatants are meant to reduce suffering. Even when war happens, not everything is allowed.

Human rights law

Human rights rules set expectations about basic dignity, such as freedom from torture, fair trials, and freedom of expression. These rights are written into documents like the Universal Declaration of Human Rights and later treaties. Although enforcement can be uneven, human rights law gives activists and states a shared language to criticize abuse.

Climate agreements

Climate change is a global issue that no single state can solve alone. Agreements like the Paris Agreement create rules for cooperation, reporting, and national commitments. States decide their own targets, but they are expected to be transparent and regularly update their plans. This shows how rules can support cooperation without creating one central authority.

Trade rules

Trade rules help reduce conflict over tariffs, subsidies, and market access. The World Trade Organization provides procedures for settling disputes. These rules are important because trade disputes can damage economies and political relationships.

In each case, rules do not eliminate power struggles. Instead, they shape how those struggles happen.

Limits of rules: when do rules fail? ⚠️

Rules are important, but they are not always effective. Some states ignore rules when they believe the costs are low or when strategic interests are high. Powerful actors may escape consequences more easily than weaker ones. This creates criticism that global rules are unevenly enforced.

Rules can also be limited by disagreement. Different states may interpret the same rule differently. For example, one government may argue that an action is self-defense, while another calls it aggression. Because interpretation matters, global politics often involves not just breaking rules but arguing about what the rules mean.

There is also the problem of weak enforcement. International law often depends on states themselves to investigate, prosecute, or sanction violations. If states do not cooperate, enforcement becomes difficult. This helps explain why some rules are respected more consistently than others.

For IB Global Politics SL, it is important to show that rules are not magically enforced. Instead, their strength depends on institutions, consent, shared interests, public pressure, and the balance of power.

How to analyze rules in an IB Global Politics way

When you answer an IB-style question about rules, try to do four things:

• Define the rule or concept clearly.
• Explain who created it and why.
• Show how it affects different actors.
• Evaluate its strengths and limits with an example.

For example, if asked whether international law is effective, students should not answer with only yes or no. A stronger response would explain that international law helps set standards, support cooperation, and increase legitimacy, but it also depends on enforcement and political will. Then use an example, such as the UN system, climate agreements, or humanitarian law.

This kind of reasoning shows balance. In global politics, very few rules are absolute. Most operate in a world of competing interests, unequal power, and changing cooperation.

Conclusion

Rules are one of the main ways global politics becomes organized rather than chaotic. They help states and other actors predict behavior, cooperate on shared problems, and judge whether actions are legitimate. At the same time, rules are shaped by power, and they are not always enforced equally. Some actors can ignore them more easily, while others use them as protection or as a tool of influence.

For the broader topic of Understanding Power and Global Politics, rules are essential because they show that power is not only about force. Power also includes the ability to make rules, shape norms, control interpretations, and build legitimacy. Understanding rules helps students understand how global order works, why cooperation happens, and why conflict often revolves around law, standards, and authority.
