World History
World History
This domain samples world history across eras and regions: early river valley civilizations, classical empires, exchange networks, the rise and spread of major religions, the Columbian Exchange, revolutions, imperialism, the world wars, decolonization, and globalization. The exam favors comparison, causation, and the movement of goods, people, and ideas across regions rather than isolated dates.
Core rules
- River valley civilizations (Mesopotamia, Egypt, Indus, Shang) developed irrigation, writing, and centralized authority; they are not identical, so compare specific institutions.
- Exchange networks moved more than goods: the Silk Roads carried Buddhism and plague; Indian Ocean trade carried Islam and monsoon-dependent shipping; trans-Saharan routes linked West Africa to the Mediterranean.
- The Columbian Exchange transferred crops, animals, and pathogens between hemispheres; smallpox devastated Indigenous populations, while horses and wheat transformed American economies.
- The Enlightenment supplied concepts of natural rights, consent of the governed, and separation of powers that shaped the American and French revolutions and later constitutions.
- Industrialization began in Britain with coal, iron, and textiles, then spread unevenly; imperialism and both world wars were tied to industrial competition and nationalist rivalry.
Worked example
A question asks for the most significant long-term effect of the Columbian Exchange on the Americas. The strongest answer identifies demographic collapse from Old World diseases, which disrupted Indigenous societies and labor systems and helped make the transatlantic slave trade central to colonial economies. Reasoning: the exchange included pathogens as well as crops and animals; the effect was not simply “new foods,” but a demographic and labor transformation that reshaped colonial societies.
Traps
Treating “the West” as the only engine of change; conflating the French Revolution’s phases; assigning the Industrial Revolution to the United States before Britain; and reading the Silk Roads as a single route rather than a network of routes and intermediaries.
