Chapter: Historical Inquiry & Indigenous NationsHistorical Inquiry: Questions, Sources & Evidence
Learning goals
- I can trace a historical claim back to the document it came from.
- I can explain why the $24 figure for Manhattan is not in any 1626 source.
- I can tell what a source proves from what it only suggests.
Before this unit
Locate the period and region using the supplied background and timeline. Define unfamiliar terms and distinguish a document’s assertion from an established outcome.
Use three flexible 40–45-minute sessions: background and Parts 1–2 with checks; Parts 3–4 and the worked evidence case; then remaining practice, a timeline or labeled model, revision, and the exit check. Complete one short part at a time. Embedded checks count toward the practice set, rather than duplicate homework. Workshop, review, quiz, exams, and flexible support have separate time.
Almost everyone has heard that the Dutch bought Manhattan from Native Americans for $24 in beads. It is one of the most repeated facts in American history. It is also, in almost every detail, wrong — and tracing how it went wrong teaches you more about history than memorising it ever could.
There is exactly one surviving source. On 7 November 1626 a Dutch official named Pieter Schagen wrote a short letter to his superiors reporting that a ship had arrived from the new colony and that the settlers “have bought the island Manhattes from the wild men for the value of 60 guilders.” Schagen was in Amsterdam. He had never seen Manhattan. He was passing on shipboard news.
That single sentence is the entire documentary basis. It does not say who sold the island, what was handed over, or what either side understood the agreement to mean. Everything else you have heard — the beads, the $24, the idea that the Lenape were cheated — was added later by people who were not there either.
Build your understanding
Where this fits
This is the first unit of the course, so it sets the method you will use in every one that follows. You are about to study three centuries in which almost everything you can know comes from documents written by a minority of the people involved. Before meeting those documents, it is worth seeing exactly how a well-known fact can be built out of almost nothing — and how to take one apart.
Use three flexible 40–45-minute sessions: the Schagen letter and what it does and does not say; where the $24 came from and what the Lenape understood; then the practice set, the source-analysis task, revision and the exit check. Workshop, review, quiz and exams have separate time.
Part 1 · One letter, eleven words of substance
The Schagen letter sits in the Dutch National Archives in The Hague and runs to a single page. The part everyone quotes is eleven words long in the original Dutch. The rest of the letter is about cargo: 7,246 beaver skins, 853 otter skins, and assorted mink and wildcat, which tells you plainly what the Dutch West India Company actually cared about. Manhattan is mentioned almost in passing, as one line of news among the shipping returns.
Notice what the document is. It is not a deed, a contract or a treaty; no such paper has ever been found. It is not an eyewitness account, because Schagen was more than three thousand miles away. It is a secondhand summary, written by an administrator, of what a ship's crew said when they docked. A historian would call it a secondary source for the purchase itself, even though it is a primary source for 1626 Dutch administration.
That distinction matters more than it sounds. A document can be genuine, old and completely reliable about one thing while being weak evidence for another. The Schagen letter is excellent evidence that the Dutch believed, in November 1626, that a transaction had happened and that 60 guilders was the figure in circulation. It is poor evidence for what was handed over or what the Lenape agreed to.
Pause and explain
Schagen's letter is genuine and dated 1626. Why is it still weak evidence for what the Lenape agreed to?
Check your reasoning after answering
Because he was in Amsterdam and never saw the transaction. He was repeating what a ship's crew reported on docking, so the letter reliably shows what Dutch officials believed had happened, not what was said or understood on the island. A document can be authentic and still be secondhand about the thing you want to know.
Part 2 · Where the twenty-four dollars came from
The letter says 60 guilders. It does not say dollars, and it does not say beads. The famous figure was produced in 1846, when the New York historian John Romeyn Brodhead converted 60 Dutch guilders of 1626 into contemporary American money and arrived at about twenty-four dollars. That number was then repeated for the next century and a half until it stopped sounding like a conversion and started sounding like a fact.
It is a bad conversion, for a reason that has nothing to do with arithmetic. Comparing money across 220 years using a simple exchange rate ignores what the money could buy. Sixty guilders in 1626 was roughly several months of a labourer's wages — estimates vary, and historians disagree, which is itself worth noticing. It was not a fortune, but the picture of a continent traded for pocket change is an artefact of the 1846 calculation, not of 1626.
The beads are not in the letter at all. Dutch trade goods of the period typically included duffel cloth, iron axes, hoes, kettles, knives and wampum — the shell beads made along Long Island Sound that carried real value in regional exchange. Later deeds from the Hudson Valley list such goods item by item. The beads entered the Manhattan story through retelling, because they made the bargain sound more lopsided and the story better. A detail that improves a story is exactly the detail to check.
Pause and explain
Someone says “the Dutch paid $24 for Manhattan.” Name two things wrong with the sentence.
Check your reasoning after answering
The currency and the date of the figure. The one source records 60 guilders, not dollars; the $24 comes from an 1846 conversion by John Romeyn Brodhead, 220 years afterwards. Converting by exchange rate also ignores purchasing power, which is why the sum sounds trivial today when it was a few months' wages then.
Part 3 · What the other side thought it was doing
The hardest problem with this story is that one side left no document. The Lenape, who lived across what is now New York City, New Jersey and eastern Pennsylvania, kept records in speech, wampum and memory rather than in writing, and no Lenape account of 1626 survives. Everything written at the time was written by the people on the other side of the exchange.
What historians can reconstruct from later Lenape and Haudenosaunee dealings is that land in this region was generally understood as something a group held and used, not something an individual could sell outright and permanently. Agreements of this kind were often understood as granting rights to share, use or pass through, renewed through continuing gifts and relationship. The Dutch, working from European property law, recorded a sale.
So the two sides may have come away from the same afternoon believing two different things had happened, and the only surviving record is in the language of one of them. This is not a detail about 1626. It is the central difficulty of the next three hundred years of this course, and it starts here.
It also explains something that will otherwise look like bad faith later. When colonists and Native nations fell out over land they had both signed for — as happened repeatedly through the 1600s and 1700s — the quarrel was often not that someone had lied, but that two legal traditions had been written down as one agreement, in one language, by one side. Recognising that is different from excusing it: the Dutch and later the English acted on their reading and took the ground.
Pause and explain
Why is the absence of a Lenape document a historical problem rather than just a gap?
Check your reasoning after answering
Because the surviving record is one-sided, and silence is easy to mistake for agreement. The Dutch wrote a sale in the terms of European property law; Lenape practice generally treated land as held and used by a group, with agreements renewed through relationship. Using only the written side risks reporting one party's understanding as what both parties meant.
Part 4 · Four questions to ask any source
From here on you will meet hundreds of documents, and the same four questions open all of them. Who made this, and were they present? When was it made — at the time, or long afterwards? Why was it made, and for whom? And what would this person have no way of knowing, even in good faith?
Run the Schagen letter through them and the answers come fast. A company administrator; not present; three weeks or so after the ship sailed, which is prompt for the news but still secondhand; written to report cargo to superiors; and he could not know what was said on the island or what the Lenape understood. None of that makes the letter worthless. It makes it precise — you now know exactly what weight it bears.
The same four questions will do real work on a 1776 pamphlet, an 1857 court ruling and an 1863 army return. They are also why historians change their minds, which is a feature of the subject rather than a failure of it: new documents turn up, old ones are reread, and a claim everyone repeated for 150 years turns out to rest on an eleven-word aside about beaver skins. When you meet a confident sentence about the past in this course, the useful reflex is not to doubt it but to ask which document it came from.
Pause and explain
Apply the four questions to a letter a Civil War soldier writes home the evening after a battle. Which question is likely to expose the biggest limit?
Check your reasoning after answering
What he could not know. He was present and wrote immediately, so he is strong on his own experience — the noise, the fear, his own regiment. But a soldier in the line cannot see the whole field, does not know casualty totals, and may not know who won. The limit is scope, not honesty.
Apply the whole unit · Take a famous claim apart
A textbook says: “In 1626 Peter Minuit purchased the island of Manhattan from the Native Americans for $24 worth of beads.” Only one contemporary source exists, and it is the Schagen letter of 7 November 1626.
Your task
Identify every element of that sentence the source does not support, and rewrite it so it claims only what the evidence carries.
What your response should show
- Separates the sentence into checkable claims rather than judging it whole
- Names 60 guilders as what the source says, and 1846 as where $24 came from
- Explains why an exchange-rate conversion across 220 years misleads about value
- States what is unknown because only one side left a written record
Response guidance — after your attempt
List the sentence's claims separately: the date, the buyer's name, the seller, the price, the currency, and the goods.
Check each against the letter, which reports that settlers “have bought the island Manhattes from the wild men for the value of 60 guilders.” Mark each supported, unsupported, or added later.
Deal with the $24 specifically: say where it came from, in what year, and why converting by exchange rate across 220 years misleads.
Write one sentence that a historian could defend, and a second naming what remains unknown.
Supported: the year, and that the Dutch recorded acquiring the island for a stated value of 60 guilders. Unsupported by this source: Minuit by name, which nation the sellers belonged to, and the beads, which appear in no contemporary record of the transaction. Added later: the $24, converted by John Romeyn Brodhead in 1846. A defensible sentence: “A Dutch report of November 1626 states that settlers acquired Manhattan for goods valued at 60 guilders.” What remains unknown: who negotiated, what was handed over, and what the Lenape understood the agreement to grant — no record from their side survives.

Parent / teacher teaching notes
Ask for one because-statement, a dated connection, and a source limitation. Give specific feedback and time to revise. Allow notes, a glossary, oral explanations, or a labeled timeline. Evaluate context, evidence, and reasoning rather than the learner’s politics, religion, cultural identity, or agreement with the model wording. Do not require family disclosure or role-play of slavery or persecution.
The key idea
Every claim about the past rests on a source, and sources were made by people with reasons. The famous story that Manhattan was bought for $24 comes from one short letter written in 1626 by a man who was not there, and the dollar figure was invented by a historian 220 years later.
Worked examples
Example 1 · Worked evidence case
- Identify the different measures: enrollment and daily presence.
- Compare the same period without treating the measures as identical.
- Seek additional dated attendance records for a term-wide claim.
Example 2 · Compare a second claim after your attempt
- Identify the relevant period, institution, or evidence category.
- They preserve access to one report, not two independent observations. Trace the original date, writer, purpose, and evidence, then compare a separately created record.
- State the narrower conclusion the supplied information can support.
Avoid these mistakes
- Mistake: An old record is automatically accurate and complete.
- Mistake: Two webpages repeating one report count as two independent witnesses.
- Treating all members of a community as one actor.
- Presenting a source’s stated aim as proof of everyone’s actual experience.
Check your understanding
Why is “Did the canal improve every life?” difficult to answer with one freight receipt?
Discuss the answer
The receipt concerns a particular shipment and cost. It cannot establish every person’s earnings, safety, displacement, or other experience; specify a narrower claim and seek additional records.
Does calling a letter a primary source prove its statements?
Discuss the answer
No. Its date and connection to the event make it relevant evidence, but its claims still need contextual reading and comparison with other information.
Words to know
- context
- The time, place, institutions, and conditions surrounding an event.
- primary source
- Evidence created in the period or activity being investigated; its form does not automatically guarantee accuracy.
- interpretation
- An explanation of evidence that can be compared with context and other records.
- corroboration
- Comparing independently produced evidence to test a claim.
- inference
- A reasoned conclusion drawn from observations; it can require further testing.
Extend the historical inquiry
If you use a linked record, identify creator, date, audience, purpose, form, and a specific claim it supports. Keep original wording separate from course paraphrase. Seek a different independently produced record that would test an inference.
In the real world
Trace a dated claim to its evidence and distinguish stated aims, institutions, and actual access. Describe people and communities without universal stereotypes.
Exit check
How can a writer improve a claim that one diary represents every resident?
Check your explanation after answering
Identify the diarist, date, and setting, describe the recorded experience, and qualify the generalization. Compare other independently produced accounts before extending it.
Explain your reasoning without notes. If a key idea is missing, revisit the lesson and try again.
Problem 1
Answer and explanation
The receipt concerns a particular shipment and cost. It cannot establish every person’s earnings, safety, displacement, or other experience; specify a narrower claim and seek additional records.
Problem 2
Answer and explanation
No. Its date and connection to the event make it relevant evidence, but its claims still need contextual reading and comparison with other information.
Problem 3
Answer and explanation
Enrollment records a listed status. Daily attendance concerns behavior at particular times; attendance logs or other independent evidence would be needed.
Problem 4
Answer and explanation
Identify the diarist, date, and setting, describe the recorded experience, and qualify the generalization. Compare other independently produced accounts before extending it.
Problem 5
Answer and explanation
The register lists 12 learners, while 9 were present on one recorded day. Three were not marked present that day, assuming the same roster and complete marking. That does not show why they were absent or their attendance throughout the term. More dates and information about the recording method would test a broader claim.
Identify the different measures: enrollment and daily presence.
Compare the same period without treating the measures as identical.
Seek additional dated attendance records for a term-wide claim.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence with an explained claim or calculation.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an assumption, evidentiary limit, or distinction that qualifies the conclusion.
Problem 6
Answer and explanation
They preserve access to one report, not two independent observations. Trace the original date, writer, purpose, and evidence, then compare a separately created record.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence with an explained claim or calculation.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an assumption, evidentiary limit, or distinction that qualifies the conclusion.
Problem 7
Answer and explanation
It identifies a period, place, activity, or relationship that available evidence can investigate; its terms are defined.
Problem 8
Answer and explanation
No. It narrows the claims the record can support. A register remains useful for enrollment even when it cannot show daily attendance.
