AP World History — the world from 1450 to 1750

Units 3 and 4 of AP World History: Modern run from about 1450 to about 1750 and are the heaviest pair in the course, worth between 24 and 30 per cent of the exam together. The first covers the land-based empires; the second covers what happened once ships began crossing oceans regularly. This set takes ten of their ideas, one question each.

Two questions exist to replace slogans with mechanisms. "Gunpowder empires" is a phrase students repeat without saying what the gunpowder did, so the first question asks precisely: artillery brought down walls built to withstand catapults, and firearms were added to cavalry armies rather than substituted for them — and the new infantry corps mattered as much politically as militarily, being paid by and loyal to the centre. The voyaging question refuses a single cause: hulls and rigs that could work to windward, instruments for latitude, learned knowledge of the Atlantic wind systems, and rulers willing to fund voyages that might return nothing. The compass, the usual single-cause answer, had been in use for centuries.

The economic questions turn on prices and risk. Silver flowed to China because Ming tax obligations came to be payable in it, which made the metal worth more there than where it was mined — the price gap is the engine, and scarcity alone would not have moved it. The joint-stock company spread risk rather than removing it: a voyage cost more than a merchant possessed and might not come back, so many subscribers each took a fraction, and shares that could be sold on meant capital was not locked up for years.

Three questions handle coercion and are written plainly. The Atlantic slave trade is named in the stem as the forced transportation and enslavement of upwards of twelve million people, and the question asks about the demand that drove it — plantations growing sugar, tobacco and later cotton, with hereditary enslavement part of the economic design. The mita is distinguished from chattel slavery by term and by heredity: a rotating conscription that expired and fell on a community, against a status held for life and passed to one's children. And the Columbian Exchange question states the Indigenous population collapse directly, notes that estimates of its scale commonly range between about half and around ninety per cent, and says the disagreement turns on the pre-contact population figure the evidence does not settle.

Every distractor is a mistake a candidate could really make, and each explanation says which one produces which answer. Nothing is quoted from a modern translation of an early modern text, since those translations are themselves in copyright; where a document or account matters, it is described and attributed.

The limit worth naming: real Section I questions come in sets of three or four built on a source. There are none here, so every question stands on its own text.

• State precisely what artillery and firearms changed about early modern warfare, and what they did not
• Explain how the Qing sustained authority by presenting the emperor differently to each population they governed
• Give the combination of ship design, instruments, wind knowledge and state finance behind sustained ocean voyaging
• Describe both directions of the Columbian Exchange, including the scale of Indigenous mortality and why historians disagree about it
• State the plantation demand that drove the Atlantic slave trade, and place its peak correctly in the eighteenth century
• Distinguish the mita from chattel slavery by who bore the obligation, for how long, and whether it was inherited
• Explain how a tax payable in silver created the price gap that pulled the metal across the world
• Contrast a trading-post empire's control of ports and shipping with a territorial empire's rule over land and people
• Account for the joint-stock company as a division of risk among many investors under a state charter
• Read the Pueblo Revolt as evidence about the thinness of colonial authority and the pressures that united separate communities

Built against the published structure of AP World History: Modern. Unit 3, Land-Based Empires, and Unit 4, Transoceanic Interconnections, both cover c. 1450 to c. 1750 and are each weighted at 12 to 15 per cent of the exam. The exam runs 3 hours 15 minutes and is taken digitally: 55 multiple-choice questions in 55 minutes for 40 per cent of the score, presented in sets built on sources; three short-answer questions in 40 minutes for 20 per cent; then a Document-Based Question with a recommended 60 minutes including a 15-minute reading period for 25 per cent, and a Long Essay Question in 40 minutes for 15 per cent. No modern translation of any early modern text is quoted in this material, published translations being themselves in copyright; real documents and accounts are described and attributed instead. No quotation, document or figure is invented and attributed to a real person or institution. Nothing is reproduced from any College Board publication, released exam or scoring guideline. Zestly is an independent study tool. It is not affiliated with the College Board, which owns the AP World History exam, and it is not an exam centre.
