global connections: 1450-1750
The period from 1450 to 1750 saw unprecedented global connections and interactions. Empires expanded, trade networks grew, and European exploration of the Americas began. These changes led to increased cultural exchange, conflict, and the emergence of new economic systems like the transatlantic slave trade. This era also witnessed significant intellectual and religious developments. The Scientific Revolution and Enlightenment challenged traditional beliefs, while the Protestant Reformation split Western Christianity. These changes, along with technological innovations and the globalization of trade, laid the foundations for the modern world.
What is Unit 4 of AP World History about?
Unit 4, Transoceanic Interconnections (c. 1450–1750), dives into the maritime and global changes that reshaped the world. You’ll study maritime technological innovations that made long-distance travel possible, European exploration and empire-building, the Columbian Exchange, changing labor systems (including the Atlantic slave trade and plantation economies), shifting social hierarchies, and how expanding global trade transformed states and societies. The unit typically spans ~22–25 class periods and counts for about 12–15% of the AP exam.

What's the hardest part of AP World Unit 4?
Many students struggle to explain and connect cause‑and‑effect across exploration technologies, empire‑building, and the Columbian Exchange. A helpful approach: sequence events (technology → voyages → empire → trade/ecological change) and practice short causation chains on FRQs. Compare imperial strategies across regions (Spain, Portugal, Dutch, Ottoman, Ming/Qing) and focus on a few strong examples rather than trying to memorize everything. Do timed practice for MCQs and short answers so you can spot links quickly. For a concise unit overview and targeted practice, use Fiveable’s Unit 4 guide (https://library.fiveable.me/ap-world/unit-4).
How long should I study Unit 4 for AP World History?
Aim for about 10–15 hours of focused review for Unit 4 as a good baseline. If this is your first thorough pass, plan toward the higher end (12–15 hours). If you’ve already covered most topics in class, 8–10 hours of targeted review and practice can be enough. Use that time to read the CED topics (4.1–4.8). Make concise notes. Do 1–2 timed multiple-choice sets and write or outline two short LEQ/DBQ-style responses. Break study into 1.5–3 hour sessions spread over several days to boost retention, and mix content review with timed practice so you don’t just recognize facts but can use them under exam conditions.
Where can I find AP World Unit 4 notes and study guides?
Check out the Fiveable Unit 4 page for Transoceanic Interconnections (c. 1450–1750) (https://library.fiveable.me/ap-world/unit-4). That page lines up with CED topics 4.1–4.8 and has concise summaries, cheat sheets, and cram videos. The College Board’s unit PDF and AP Classroom review videos also outline the official scope and weighting (12–15% of the exam), so compare both sources to make sure you cover everything.
