Your turn to be the historian
In the first lesson you met the label "Age of Enlightenment" and the warning that period labels are interpretations. Now you have studied absolutism and constitutional government, the Qing, Tokugawa, Ottoman, Safavid and Mughal states, science and the Enlightenment, the world economy, the slave trade, Indigenous diplomacy and resistance, wars for empire, European companies in Asia, Africa and the Pacific, the American Revolution, and culture and religion across the world.
In this lesson you carry out a complete inquiry: Was 1650–1789 an "Age of Enlightenment" for the world? This is the kind of question you will answer in a first-year university history essay.
Step 1: Formulate the question (A1.1)
The big question is evaluative. Break it into sub-questions of different types:
- Factual: What did Enlightenment thinkers argue? Which reforms were made?
- Comparative: How did life change for a French peasant, a Qing scholar, an enslaved person in Jamaica, a Cree trader?
- Causal: Why did rights ideas spread in some places and not in others?
- Evaluative: For whom, and by what criteria, was this an age of "enlightenment"?
Then set criteria. For example: (1) new ideas about reason and rights; (2) changes in government; (3) changes in ordinary people's lives; (4) how many people, in how many regions, were affected.
A clear plan keeps an inquiry focused. Every step uses the historical thinking concepts.Step 2: Gather and organize evidence (A1.2, A1.3)
Use at least one source from four regions. Possible evidence from this unit:
- Primary: Locke's Two Treatises (1689); the Bill of Rights (1689); Montagu's 1717 letter on inoculation; Kant's "What is Enlightenment?" (1784); the Declaration of Independence (1776); Equiano's Narrative (1789); the Royal Proclamation (1763) with the wampum and oral history of Niagara (1764); casta paintings; Rigaud's portrait of Louis XIV; Burke's speeches against Hastings.
- Secondary: historians' interpretations, such as the "decline vs. transformation" debate about the Mughals, Beik's view of absolutism, Carretta's research on Equiano, and the Slave Voyages estimates.
Organize evidence in a table with columns: source, type, region, what it shows, perspective and reliability, which criterion it supports. Check each source's credibility: who made it, when, for whom, and why? Corroborate important claims.
Sort evidence into support and challenge for a claim. The strongest conclusions account for both.Step 3: Interpret, analyse and conclude (A1.4, A1.7)
Look for patterns:
- Enlightenment ideas were real and influential, especially in Europe and the Americas, and had parallels elsewhere (Qing evidential research, Japanese Dutch learning).
- Changes in government were limited: constitutional government in Britain and the US; enlightened absolutism with mixed results.
- For many people, the period meant greater suffering: the slave trade peaked; Indigenous peoples lost land; famine struck Bengal.
- In Asia, the most important developments (Qing expansion, Mughal decentralization, Tokugawa peace) had little to do with the European Enlightenment.
Now write a qualified thesis: a clear judgement with limits.
Worked exampleModelled example: From evidence to a thesis paragraph
Write a thesis and the outline of one body paragraph for the inquiry question.
- Thesis: "Between 1650 and 1789 the Enlightenment produced powerful ideas of reason and rights, but it was an 'age of enlightenment' mainly for educated elites in Europe and the Americas; for millions of enslaved Africans and many Indigenous peoples it was an age of intensified exploitation, and in much of Asia it was largely irrelevant to the main developments."
- Topic sentence (body paragraph 2): "The same century that celebrated natural rights saw the transatlantic slave trade reach its peak."
- Evidence: more than half of the roughly 12.5 million Africans forced across the Atlantic were taken in the 1700s (Slave Voyages estimates); Locke invested in the Royal African Company; the US Constitution protected slavery in 1787.
- Analysis: rights were defined to exclude enslaved people; Enlightenment thinkers offered tools for abolition, but resistance by enslaved people and religious activism were at least as important.
- Counter-argument and reply: "Some argue that Enlightenment ideas led directly to abolition. However, before 1789 only a few places (such as Vermont and Pennsylvania) had begun to end slavery, and the slave trade was still growing."
- Link: "Thus, judged by the criterion of ordinary people's lives, the period was not an age of enlightenment for most of the Atlantic world's population."
A strong answer has a qualified thesis, criteria, evidence from several regions, analysis of perspective, and a counter-argument. Each fact that is not common knowledge gets a footnote.
Step 4: Communicate and cite (A1.8, A1.9)
At university, history papers usually use the Chicago Manual of Style notes-and-bibliography system. (Other subjects use MLA or APA; follow your instructor.)
Footnote for a book (first reference):
- Vincent Carretta, Equiano, the African: Biography of a Self-Made Man (Athens: University of Georgia Press, 2005), 15.
(The page number 15 is only an example; always give the page where your information actually appears.)
Bibliography entry for the same book:
Carretta, Vincent. Equiano, the African: Biography of a Self-Made Man. Athens: University of Georgia Press, 2005.
Website (bibliography): give the author or organization, the page title in quotation marks, the site name, and the URL, with an access date if no publication date is shown. For example: Slave Voyages. "Trans-Atlantic Slave Trade: Estimates." Accessed 15 October 2026. https://www.slavevoyages.org.
Rules of thumb: cite every quotation, every statistic and every idea that is not your own or common knowledge. Citing protects you from plagiarism, and it lets your reader check your evidence.
Each part of a footnote has a job. The page number (15 here is only an example) tells the reader exactly where to look.Step 5: Skills beyond the classroom (A2)
The skills in this inquiry are used in many careers and in everyday life:
- Law: Indigenous rights cases (such as Marshall, 1999) depend on historical evidence about treaties from the 1700s, including oral history. Lawyers and expert historians analyse these sources.
- Museums, archives and heritage: curators and archivists judge sources, write labels for the public and decide what is preserved.
- Journalism and policy: analysts check claims, find primary sources and explain the background to current events.
- Data and research: projects such as Slave Voyages combine historical sources with databases; digital history is a growing field.
- Everyday life: checking whether a viral post is credible uses the same questions as checking a 1700s pamphlet: Who made this? For whom? Why? Can I corroborate it?
Current events often have roots in this period: treaty relationships and land claims in Canada, debates about monuments to slave traders, reparations, and the history behind Australia Day all trace back to 1650–1789.
Just for funWhy did the footnote get promoted?
Because it always supported the main argument, and it never took credit for someone else's work.
Hands-on activityYour inquiry: a 600-word answer
You need: your notes from this unit, a device or library, and two or three sessions of about 40 minutes.
- Choose one question: (a) Was 1650–1789 an "Age of Enlightenment" for the world? (b) Which was more significant for world history, the Scientific Revolution or the transatlantic slave trade? (c) To what extent did Indigenous nations of the Americas shape the outcome of European colonial wars?
- Set three criteria.
- Build an evidence table with at least six sources (at least two primary) from at least three regions.
- Write a qualified thesis, two body paragraphs and a conclusion that answers a counter-argument (about 600 words).
- Add Chicago-style footnotes and a bibliography.
- Ask a grown-up to read it and tell you which sentence is your thesis. If they cannot find it, make it clearer.
Look for: a clear thesis; evidence from several regions; analysis of perspective and reliability; a counter-argument; correct citations.
Your turn
1Why is "Was 1650–1789 an Age of Enlightenment for the world?" an evaluative question?
It asks for a judgement ("was it?") that must be argued with evidence and criteria, not a single fact.
2Give two criteria you could use to judge whether a period was an age of progress.
Examples: new ideas about reason and rights; changes in government; changes in ordinary people's lives; how many people and regions were affected; how long the changes lasted.
3What does it mean to corroborate a source?
To check it against other independent sources to see whether they agree.
4What is a qualified thesis? Give an example.
A clear judgement with limits. Example: "The Enlightenment transformed political ideas in Europe and the Americas, but it changed little for most people in Asia and worsened conditions for many enslaved Africans."
5Write the Chicago bibliography entry for Carretta's book.
Carretta, Vincent. Equiano, the African: Biography of a Self-Made Man. Athens: University of Georgia Press, 2005.
6When must you cite a source?
For every quotation, every statistic, and every idea or interpretation that is not your own or common knowledge.
7Name two careers that use historical inquiry skills, and one skill each uses.
Examples: lawyer (analysing treaty evidence), archivist (judging and preserving sources), journalist (checking claims), museum curator (communicating to the public), policy analyst (explaining background).
More practice: warm-up
1Which citation style do university history papers usually use?
The Chicago Manual of Style (notes and bibliography).
Presenting someone else's words or ideas as your own without credit.
3Where does a footnote appear?
At the bottom of the page, numbered to match a number in the text.
4Is the Declaration of Independence a primary or secondary source for 1776?
5What is a counter-argument?
The strongest argument against your thesis, which you acknowledge and answer.
More practice: on your own
1Why should your evidence come from several regions for this inquiry?
Because the question is about the world. Using only European sources would build in Eurocentrism and could not test whether the label fits Asia, Africa or the Americas.
2Explain how the Royal Proclamation and the Treaty of Niagara wampum could both be used in this inquiry.
Together they show how rights and land were defined in written British law and understood by Indigenous nations as an alliance. They test whether "enlightened" ideas about consent applied to Indigenous peoples, and how far Indigenous diplomacy shaped outcomes.
3Why is Equiano's Narrative useful even though part of it is debated?
Most of it is corroborated and it gives a rare first-person Black perspective on the slave trade and abolition; the debate concerns his birthplace, not the whole book. Historians use it carefully alongside other sources.
4How does a counter-argument make an essay stronger?
It shows you have considered other interpretations, makes your thesis more precise, and persuades readers who might disagree.
5Connect one current event to 1650–1789.
Examples: treaty and land-claim negotiations in Canada (Royal Proclamation, Peace and Friendship Treaties, Haldimand grant); debates about statues of slave traders and reparations; Australia Day debates (1788); Indigenous rights court cases using 18th-century evidence.
Challenge
1Write a qualified thesis for: "Which was more significant for world history, the Scientific Revolution or the transatlantic slave trade?"
Example: "Measured by the number of lives directly changed between 1650 and 1789, the transatlantic slave trade was more significant, uprooting more than six million people in the 1700s alone and reshaping three continents; but measured by long-term influence on how humans understand nature, the Scientific Revolution's methods have had a wider and longer-lasting impact." Any strong answer names criteria and makes a clear judgement.
2Critique this thesis and rewrite it: "The Enlightenment was good."
Problems: too vague ("good" for whom? in what way?), no criteria, no time or place, impossible to support with evidence. Rewrite: "Enlightenment ideas of natural rights and the separation of powers shaped constitutional government in Britain and the United States by 1789, but their application was limited to property-owning white men, which later movements for abolition and women's rights exposed."
3Explain how the four historical thinking concepts each contribute to answering the unit inquiry question.
Significance: which developments mattered most, to whom. Cause and consequence: how ideas, trade and war led to revolutions and to suffering. Continuity and change: what changed (science, constitutions) and what did not (social hierarchies, most people's lives). Perspective: how a philosophe, an enslaved person, a Qing official or a Haudenosaunee leader would judge the period. Using all four produces a rounded, defensible answer.

For parents and teachersBig idea: This culminating lesson practises the full Strand A inquiry process: formulating questions (A1.1), selecting and organizing evidence (A1.2), assessing credibility (A1.3), interpreting and analysing (A1.4), evaluating and synthesizing (A1.7), communicating (A1.8) and documenting sources (A1.9), plus transferable skills and careers (A2), drawing on all of Strand C.
How to help: Read your teen's 600-word answer. Ask them to point to the thesis, the criteria, one primary source and the counter-argument. Check that footnotes appear for statistics and quotations.
Common difficulties: A thesis that is too vague; evidence only from Europe; citing websites without author or date; summarizing instead of arguing. This is excellent preparation for first-year university essays.
Citation note: The citation examples follow Chicago notes-and-bibliography style; check the current edition or your teacher's guide for small details such as access dates.
