globalization: 1900 to today
Globalization has transformed the world since 1900, connecting economies, cultures, and societies. From early 20th century trade to post-WWII economic integration, the world has become increasingly interconnected through technology, trade agreements, and multinational corporations. This era has seen economic liberalization, cultural diffusion, and the rise of global institutions. It's brought prosperity to many but also criticism for exacerbating inequality and environmental issues. Understanding globalization is key to grasping modern international relations and economics.
What topics are covered in AP World Unit 9 (1900–present)?
You'll study major 20th–21st century global developments across topics 9.1–9.9. Expect advances in communication, transportation, and energy. Learn about the Green Revolution and birth-control technologies, plus disease, pandemics, and public-health responses. Environmental issues—pollution, deforestation, and climate change—are central. Global economic change shows up as neoliberalism, multinational corporations, and evolving trade networks. Social and political reform movements include decolonization, civil-rights struggles, and feminism. Cultural globalization covers media, migration, and consumer culture, while resistance to globalization and alternative models are also explored. Finally, international institutions (League/UN, IMF, World Bank) and their roles are examined. The unit emphasizes connections, continuity, and change across regions from 1900 to the present.
Where can I find an AP World Unit 9 PDF summary or notes?
Check out Fiveable’s focused Unit 9 study guide and resources (https://library.fiveable.me/ap-world/unit-9). That page includes cheatsheets and cram videos that work well as PDF-style summaries for quick review. If you need an official PDF, the College Board’s AP Course and Exam Description lists topics 9.1–9.9 and exam weighting (https://apcentral.collegeboard.org/media/pdf/ap-world-history-modern-course-and-exam-description.pdf). Use Fiveable for concise, student-friendly notes and practice, and the College Board doc for the formal unit description and exact wording.
How much of the AP World exam is Unit 9 (1900–present)?
Don't expect a single fixed percentage for Unit 9. The College Board organizes exam weighting by themes and skills across the whole course rather than by one unit. In practice, modern/globalization topics tend to appear modestly—usually a few multiple-choice items and the occasional short- or long-answer prompt. So, roughly one to a few percent of total points might tie specifically to Unit 9 content, with related concepts showing up elsewhere. For the exact exam structure and how topics are distributed, consult the AP World Course and Exam Description on AP Central (https://apcentral.collegeboard.org/media/pdf/ap-world-history-modern-course-and-exam-description.pdf).
What's the best way to study Unit 9 for AP World (globalization and modern era)?
Focus on themes and connections, not memorizing isolated facts. Make a concise timeline of major 20th–21st century events and innovations: tech, public health, environmental milestones, and major economic policy shifts. Create 1–2 concept maps linking technology, economy, culture, and politics. Practice mixed multiple-choice sets and one or two short/free-response questions that emphasize causation and continuity/change. Keep brief review sheets for key terms and run timed practice to build pacing. Finally, review international institutions and a few cross-regional case studies so you can apply concepts in different contexts.
How hard is Unit 9 compared to other AP World units?
Think of Unit 9 as generally less content-dense than many earlier chronological units (like Units 3–6). It emphasizes broad themes—globalization, technology, the environment, disease, and institutions—rather than long lists of discrete facts. That makes memorization easier, but it still demands strong analytical skills: causation, continuity and change, and comparison for DBQs and short answers. How hard it feels depends on your ability to synthesize cross-regional examples. If you practice connecting examples across regions and explaining causes and effects, you’ll probably find Unit 9 quite manageable.
How long should I study Unit 9 to master its themes and key concepts?
Plan on about 8–12 hours total spread across 1–2 weeks to really master Unit 9. The CED lists roughly 8–10 class periods for this unit, and it typically counts for about 8–10% of the exam. Break your time into focused blocks: 1–2 hours reading each major topic (9.1–9.9), 30–60 minutes watching a cram video or reviewing notes, and 1–2 hours doing targeted practice questions plus a short DBQ/LEQ outline. Use spaced retrieval with short daily reviews and schedule one full timed practice set the week before the test. If you must cram, two intense days of 6–10 hours can get you to a passing-level review, but spaced study gives better retention and deeper theme mastery.

What percentage of AP World multiple-choice/SAQs/DBQs typically draw on Unit 9 topics?
Unit 9 generally makes up about 8–10% of the AP World exam (the CED labels Globalization, c.1900–present as ~8–10% of course weighting). That means roughly that share of multiple-choice, SAQs, and FRQs combined will draw on Unit 9 themes across the exam, but the College Board doesn’t publish a precise breakdown by question type (MCQ vs SAQ vs DBQ). Expect Unit 9 content to appear in a mix of item types, so plan review time and practice accordingly. Focus on varied practice—MCQs, SAQs, and at least one DBQ/LEQ outline—so you’re ready no matter how the questions use Unit 9 material.

Where can I find AP World Unit 9 practice tests or MCQs?
You'll find Unit 9 practice questions and MCQs on Fiveable’s Unit 9 page (https://library.fiveable.me/ap-world/unit-9). For extra timed MCQ practice across the course, use Fiveable’s practice bank (https://library.fiveable.me/practice/world), which offers 1,000+ questions with explanations. The College Board posts past free-response questions and some exams on AP Central, but full multiple-choice sections from every past exam aren’t all publicly released. So for targeted Unit 9 drills and convenient practice, Fiveable’s unit page and practice bank are the most user-friendly options. Also check the cheatsheets and cram videos on the unit page if you need quick topic refreshers before practice.
