9.9 Continuity and Change in a Globalized World

AP World History: Modern · AP (Advanced Placement) · 5 min read · Updated: 7 Sept 2026

Welcome to the Finish Line: Topic 9.9!

You’ve made it to the final topic of the final unit of AP World History! Topic 9.9: Continuity and Change in a Globalized World is designed to help you zoom out and look at the big picture. Instead of giving you a bunch of new facts to memorize, this chapter asks you to take everything you learned in Unit 9 and organize it into a strong historical argument.

Think of this as the "Final Boss" level where you use all the "power-ups" (evidence) you collected in the previous chapters. We will focus on Continuity and Change Over Time (CCOT)—what stayed the same and what shifted as the world became more interconnected after 1900.

Note: For a deep dive into the specific facts mentioned here, see Topics 9.1 through 9.8.

1. Understanding the "Big Picture" of Unit 9

Globalization didn't just happen overnight. It is a process that accelerated rapidly after 1900 due to new technologies and shifting political ideas. When you look at Unit 9 through the lens of CCOT, you are asking: "How is our global world different from the world of 1900, and how is it surprisingly similar?"

What Changed? (The Big Shifts)

Technological Speed: Transportation and communication went from "fast" (steamships and telegraphs) to "instant" (commercial jets and the Internet). This "time-space compression" makes the world feel smaller.
Economic Ideology: Many nations shifted toward free-market policies (neoliberalism). Leaders like Ronald Reagan (USA), Margaret Thatcher (UK), and Deng Xiaoping (China) promoted these ideas to encourage global trade.
The Nature of Work: There is a new divide between knowledge economies (like Finland and Japan), which focus on information and tech, and manufacturing economies (like Vietnam and Mexico), where most physical goods are produced.
Global Governance: The creation of massive international organizations like the United Nations (UN) and the World Trade Organization (WTO) to manage global problems.

What Stayed the Same? (The Continuities)

Economic Competition: Just like the empires of the 1700s, modern states and multinational corporations (like Nestlé or Nissan) still compete for resources and market share.
Resistance to Change: Whenever culture or economics becomes "global," there is a pushback. People still value their local identities, leading to resistance to globalization (as seen in anti-IMF protests).
Human-Environment Interaction: Humans still rely on the Earth for resources, and our activities still cause environmental debates (like those over climate change).

Key Takeaway: While the speed and scale of global interaction have increased dramatically since 1900, the underlying human desires for profit, power, and cultural identity have remained constant.

2. Breaking Down the Themes of Globalization

To write a great essay on this topic, it helps to look at specific themes. Don't worry if these seem tricky at first; they are just different "flavors" of history!

Theme: Technology and Innovation (TEC)

Change: After 1900, new technologies drastically changed how we live. The Green Revolution used chemicals and genetically modified seeds to increase the food supply. Medical advances like vaccines and antibiotics helped people live longer.

Continuity: However, technology still creates "winners" and "losers." Just as the Industrial Revolution favored some nations over others, the "digital divide" today means some regions have much better access to tech than others.

Theme: Economics (ECN)

Change: The rise of regional trade blocs like ASEAN and NAFTA changed how countries trade by lowering taxes (tariffs) between neighbors. Many countries that used to be colonies became manufacturing hubs for global brands.

Continuity: Trade routes still exist to move goods from where they are made to where they are consumed. Whether it’s silk on a camel or an iPhone on a container ship, the concept of global exchange hasn't changed.

Theme: Social Interactions (SIO)

Change: There have been major calls for reform. Movements for human rights and the end of racial/gender discrimination became global. The Universal Declaration of Human Rights is a perfect example of a new, global standard for how people should be treated.

Continuity: Despite these changes, social hierarchies and inequalities persist. Access to healthcare and education still varies wildly based on wealth and location.

Memory Trick: Think of globalization like a smartphone update. The "operating system" (how humans act) is mostly the same, but the "apps" and "hardware" (technology and organizations) are way more advanced than they were in the 1900 version.

3. How to Ace the "CCOT" Argument

Since Topic 9.9 is an argumentation chapter, you might see a prompt asking you to "Evaluate the extent to which globalization changed the world after 1900." Here is a step-by-step way to build that argument:

Step 1: The Thesis (The "Roadmap")
Your thesis should acknowledge both change and continuity.
Example: "While advancements in communication technology and the rise of free-market economics fundamentally changed global interactions after 1900, the persistence of cultural resistance and economic inequality represents a significant continuity."

Step 2: Contextualization (The "Backstory")
Briefly mention what happened before 1900 to set the stage. You could mention the Industrial Revolution or Imperialism as the "roots" of modern globalization.

Step 3: Evidence (The "Facts")
Use specific terms from Unit 9. If you are talking about economic change, mention Deng Xiaoping or knowledge economies. If you are talking about continuity, mention the ongoing struggle with diseases of poverty like malaria or cholera.

Step 4: Complexity (The "Nuance")
To get the highest points, explain why a continuity remained or why a change was so significant. For example, explain that while social media (change) allows culture to spread, it also allows groups to organize and protect their local traditions (continuity).

4. Quick Review Box

Check your understanding:

Change: Shift from industrial manufacturing to knowledge-based economies in some nations.
Continuity: The continued presence of global inequality and the spread of infectious diseases.
Change: The rise of global culture (consumerism, social media, global brands).
Continuity: Persistent resistance to globalization by people wanting to protect local industries or values.
Key Institutions: UN, WTO, NAFTA, ASEAN (These are the "tools" of modern change).

Common Mistake to Avoid: Don't say that globalization started after 1900. It has been happening since Unit 2 (Silk Roads) and Unit 4 (Columbian Exchange). What happened after 1900 was that it became faster, more intense, and reached almost everyone on Earth.

Quick check

Can you answer these now?

Open each question to check the key ideas from this chapter.

In the context of AP World History Unit 9, what is the significance of Continuity and Change Over Time (CCOT)?

CCOT analyzes how global interconnectedness shifted rapidly after 1900 due to technology and politics while identifying underlying human patterns that remained stable.

What technological shift characterizes the change in global interactions after 1900?

Transportation and communication evolved from the 'fast' speeds of steamships and telegraphs to 'instant' connectivity through commercial jets and the Internet.

Which economic ideology became dominant in many nations during the late 20th century to encourage global trade?

Free-market policies, also known as neoliberalism, became the dominant economic ideology.

How does a "knowledge economy" differ from a "manufacturing economy" in the modern era?

Knowledge economies (e.g., Finland, Japan) focus on information and technology, while manufacturing economies (e.g., Vietnam, Mexico) focus on the physical production of goods.

What is a major economic continuity between the modern era and the 1700s?

States and large-scale organizations (now multinational corporations) still engage in intense competition for resources and market share.

How did the Green Revolution and medical advances represent a technological change after 1900?

The Green Revolution increased the global food supply through chemicals and GMOs, while vaccines and antibiotics significantly extended human life expectancy.

What are regional trade blocs, and how did they change global economics?

Trade blocs like ASEAN and NAFTA are groups of neighboring countries that lower or eliminate tariffs to encourage regional trade.

What document represents a global change in social standards regarding human rights?

The Universal Declaration of Human Rights established a new, global standard for the fair treatment of all people regardless of race or gender.

What is the most effective way to structure a thesis for a CCOT argument in AP World History?

A strong thesis must acknowledge both the significant changes and the important continuities within the specified timeframe.

What is a common historical mistake to avoid when discussing the origins of globalization?

The mistake is claiming globalization started after 1900; it actually began centuries earlier with events like the Silk Road and the Columbian Exchange.
