TLDR
After 1900, especially after World War II, states built new international organizations like the United Nations to keep the peace and work together across borders. AP World History focuses on how and why globalization changed the way states interact, so the big idea is cooperation through institutions, not the fine print of every organization.

Why This Matters for the AP World History Exam
Topic 9.8 supports a clear skill: explaining how and why globalization changed international interactions among states. The required content here is narrow. The one development you must know is that new international organizations, including the United Nations, formed with the stated goal of maintaining world peace and facilitating international cooperation.
Everything else in this guide (the WTO, IMF, World Bank, EU, ASEAN, trade agreements) works as supporting examples that show what global cooperation looked like in practice. On the exam, you can use these institutions as evidence in free-response answers about causation, continuity and change, or comparison in the period after 1900. Focus on explaining why states chose to cooperate through organizations rather than acting alone.
Key Takeaways
- The required development is that new international organizations, including the United Nations, formed to maintain world peace and promote international cooperation.
- The UN (founded 1945) replaced the weaker League of Nations and was designed to be more effective at preventing conflict and coordinating between states.
- Economic institutions like the World Bank and IMF (both from the 1944 Bretton Woods Conference) and the WTO (1995) show cooperation extending into trade and finance. Treat these as examples, not required names.
- Regional groups like the European Union and ASEAN show that cooperation happened at the regional level too, not just globally.
- The pattern that matters for AP World History is the shift toward multilateral cooperation as globalization tightened connections between countries.
- Many of these institutions face criticism over inequality, bureaucracy, and Western influence, which gives you balance for argument-based answers.
Political Institutions and Global Governance
The United Nations
The United Nations is the required example for this topic, so know it well. After World War I, the League of Nations was created to keep the peace, but it failed, partly because major powers like the United States never joined and it had weak enforcement power.
After World War II, states created the United Nations in 1945 to do the job more effectively. The UN's stated goals are to maintain international peace, promote human rights, and support development among member states.
- Founded: 1945
- Headquarters: New York City
- Members: 193 countries
- Key bodies:
- General Assembly: Every member nation gets one vote and passes resolutions that set global priorities.
- Security Council: Five permanent members (United States, United Kingdom, France, China, Russia) plus 10 rotating members. It can authorize military force and peacekeeping missions.
- Secretariat: The administrative branch led by the Secretary-General that runs daily operations.
- International Court of Justice: Settles legal disputes between countries and gives legal advice on international issues.
The takeaway for AP World History is the why: states built the UN because an interconnected world made acting alone riskier, and they wanted a shared place to manage conflict and cooperation.
UN Peacekeeping Missions
Instead of treating war as a first resort, the UN promotes conflict prevention and diplomacy. When needed, it deploys peacekeeping forces (military, police, and civilian personnel from many nations) to reduce tensions and help maintain peace after conflicts.
- Often cited as more successful: Mozambique, El Salvador, Cambodia
- Often cited as struggles or failures: Rwanda (1994 genocide), Somalia (1993)
Peacekeeping has real limits. Missions are sometimes criticized for slow response times because diplomatic negotiations and host-nation consent can delay action. These examples are useful evidence, not required content, so use them to support a point about how cooperation works in practice.
Economic Institutions and Global Trade
These economic bodies are application examples. They are not the required content for this topic, but they show globalization deepening through cooperation on trade and finance.
World Trade Organization
The WTO, founded in 1995, replaced the General Agreement on Tariffs and Trade (GATT). It works to make international trade flow more freely by reducing tariffs, mediating trade disputes, and promoting fair trade practices.
- Core principles: Non-discrimination, transparency, fair competition
- Headquarters: Geneva, Switzerland
The World Bank
Established at the 1944 Bretton Woods Conference, the World Bank was first designed to help rebuild Europe after World War II. It later shifted toward helping developing nations.
- Primary goals: Infrastructure development, poverty reduction, economic growth
- Two main branches:
- IBRD (International Bank for Reconstruction and Development): Loans to middle-income and creditworthy low-income countries.
- IDA (International Development Association): Interest-free loans and grants to the poorest countries.
International Monetary Fund
Also founded in 1944, the IMF works to promote global financial stability and prevent economic crises. Unlike the World Bank, which funds long-term development projects, the IMF provides short-term financial help and policy advice to countries facing balance-of-payment problems.
Regional Economic Organizations
European Union
The EU grew out of the European Economic Community, created in 1957 to promote regional economic integration. Over time it expanded into a single market with a common currency (the euro) and a parliamentary structure.
- Goals: Economic integration, social cohesion, environmental sustainability
- Members: 27 European countries
- Institutions: European Commission, European Parliament, European Central Bank
Association of Southeast Asian Nations
Founded in 1967, ASEAN promotes political stability and economic growth in Southeast Asia. It encourages free trade among members and looks for regional solutions to shared challenges.
- Members: 10 nations, including Indonesia, Thailand, and Vietnam
- Focus: Economic cooperation, regional peace, and cultural exchange
Free Trade Agreements
Free trade agreements remove tariffs and other barriers to encourage trade between member nations. They often boost competition and growth by expanding access to global markets. Use them as examples of economic cooperation, not as required terms.
| FTA | Members | Purpose |
|---|---|---|
| NAFTA (now USMCA) | U.S., Canada, Mexico | Promote trade across North America; replaced by USMCA in 2020 |
| Trans-Pacific Partnership (TPP) | Australia, Japan, Chile, others (U.S. withdrew in 2017) | Facilitate trade across the Pacific Rim |
| Mercosur | Brazil, Argentina, Uruguay, Paraguay | Promote economic integration in South America |
| African Continental Free Trade Area (AfCFTA) | 50+ African nations | Boost intra-African trade and industrialization |
FTAs can be bilateral (between two countries) or multilateral (three or more). When conflicts arise, the WTO often steps in to mediate and enforce compliance. A tariff is a tax placed on imported or exported goods, and FTAs usually reduce or eliminate them to stimulate trade.
How to Use This on the AP World History Exam
Free Response
If a prompt asks about how globalization changed interactions among states, lead with the required idea: states formed new international organizations like the United Nations to maintain peace and cooperate. Then bring in specific institutions as evidence. The UN is your strongest example because it is directly tied to this topic.
Practice connecting cause and effect. For a causation prompt, explain why two world wars and tightening global connections pushed states toward shared institutions. For continuity and change, contrast the failed League of Nations with the more durable UN, and show how economic cooperation expanded through bodies like the WTO and regional groups.
Using Sources Effectively
For multiple-choice sets or document-based work, you might see charters, speeches, or data tied to international organizations. Ask what the source reveals about a state's reasons for cooperating, and watch for point of view. A document praising an institution and one protesting it can both be useful evidence about globalization's mixed effects.
Common Trap
Do not turn this topic into a memorization list of every organization and founding date. The exam rewards explaining the why behind cooperation more than reciting names. Use the extra institutions to support analysis, not to replace it.
Common Misconceptions
- The UN did not end war or replace national governments. It is a forum for cooperation and peacekeeping, and its power depends on member states agreeing to act.
- The League of Nations and the United Nations are not the same thing. The League came after World War I and failed; the UN came after World War II and was built to be stronger.
- The World Bank and the IMF are not interchangeable. The World Bank funds longer-term development, while the IMF gives short-term help for financial and balance-of-payment crises.
- International institutions are not neutral or universally praised. Many people criticize them for unequal outcomes, heavy bureaucracy, and disproportionate Western influence, and that criticism is fair to mention in arguments.
- These organizations are examples that support the topic, not a required checklist. The one development you must know is that new international organizations, including the United Nations, formed to maintain peace and promote cooperation.
