Thematic and Comparative History
This domain tests comparison and long-run themes: trade, migration, disease, technology, environment, gender and revolution. The exam checks whether your comparison is disciplined - criteria, comparable units, and a conclusion - or merely parallel description.
Core rules and concepts
- Comparability: compare like units over comparable periods (state with state, empire with empire); mismatched units invalidate the conclusion.
- Fix criteria before evidence. Choose three or four dimensions - social base, economy, ideology, outcome - and apply them identically to both cases.
- Periodisation is an argument. Calling a period 'early modern' asserts a claim about what changed and where.
- Scale matters: local, national and global framings produce different answers about the same theme.
- Comparison is not causation. Shared features may come from diffusion, from similar constraints, or from coincidence.
Worked example
Prompt: compare the Atlantic revolutions. Criteria: social base, slavery, citizenship, outcome. The American revolution excluded enslaved people from the political nation; the French abolished slavery in 1794 and Napoleon restored it in 1802; Haiti's revolution (1791–1804) was driven by an enslaved majority and produced independence under racial exclusion and economic isolation. Conclusion: the same vocabulary of rights produced opposite results because plantation economies and racial orders differed - so 'revolution' must be defined before comparison.
Traps
Parallelomania - asserting similarity from surface resemblance. Comparing a state with a civilisation. Using comparison to smuggle in causation. Claiming uniqueness without establishing a baseline.
