✍️ DBQ / LEQ / SAQ Writing Shortcuts
| Component | Quick Tip |
|---|---|
| Thesis | One defensible claim + line of reasoning. Must go BEYOND the prompt. "Although [concession], [your argument] because [reason 1], [reason 2], [reason 3]." Place in intro AND restate in conclusion. |
| Contextualization | Historical context from a DIFFERENT time/place than the prompt that connects to your argument. Full paragraph (3+ sentences). "In the centuries preceding [topic], the development of [X] laid the groundwork for..." |
| Evidence (DBQ) | Use at least 3 documents for any credit; at least 6 documents for the evidence point. Quote or paraphrase — don't just list doc numbers. Connect each doc to your argument. |
| HAPP / Sourcing | For each doc, explain how Historical Context, Audience, Purpose, or Point of View affects the argument. "As an Ottoman official (POV), the author would likely emphasize imperial strength over weakness." |
| Outside Evidence (DBQ) | One specific fact not in the documents + explanation earns the point. Must be substantive — "the Mongols also conquered Persia" with context, not just a name-drop. |
| Complexity | Qualify, corroborate across time/region, or explain cause & effect at multiple scales. One well-explained complexity example with explicit connection to your argument earns the point. |
| CCOT (continuity & change over time) | Structure: What changed? What stayed the same? Identify a turning point with a specific cause. Don't just say "things changed" — identify what force caused the change (trade, conquest, technology, etc.). |
🔄 Common CCOT / Comparison Topics
| Topic | Key Change | Key Continuity |
|---|---|---|
| Role of women (classical → postclassical) | Confucianism/footbinding limited Chinese women; Islam gave limited property rights | Patriarchal systems persisted across most civilizations |
| Labor systems (1450–1750) | Coerced labor (mit'a, encomienda) replaced or supplemented earlier systems; Atlantic slave trade emerged | Peasant agriculture and tribute systems continued in most regions |
| Trade networks (600–1450 → 1450–1750) | Portuguese entered Indian Ocean (disrupted); Atlantic trade network created | Indian Ocean, Silk Road, and Trans-Saharan trade continued |
| State consolidation (c. 1450–1750) | Gunpowder empires centralized power; joint-stock companies created quasi-state trading power | Religious legitimacy remained central to most rulers' authority |
| Industrialization impacts (c. 1750–1900) | Factory system replaced cottage industry; urban migration; new middle class | Rural agricultural labor continued to dominate most of the world outside Western Europe |
