Most people assume history is a settled body of facts — names, dates, and events that someone has already sorted out, and that your job is simply to learn. That assumption falls apart the first time you read two good historians who examined the same evidence and reached different conclusions. Neither one is lying. Neither one is careless. So what exactly is going on?

The answer is that the past and history are not the same thing. The past is everything that ever happened, and it is gone beyond recovery. History is the account we build of the past out of the fragments that survive — and building an account requires choices. Which questions to ask. Which sources to trust. What counts as a cause rather than a coincidence. Which of the millions of things that happened are significant enough to belong in the story at all. Historiography is the study of those choices: not what happened, but how we come to know it, argue about it, and revise what we thought we knew.

Perspective is unavoidable. Distortion is not. — the working principle of this unit

That distinction is the whole point. Recognizing that every historian writes from a point of view does not mean every account is equally good, and it does not mean the truth is unknowable. It means we need standards for telling careful work from sloppy work: sourcing, contextualization, corroboration, fair treatment of evidence that cuts against your argument, and a willingness to be corrected. These three lectures give you those standards and then put them to work on a single, familiar stretch of the American Revolution — so you can watch the same evidence yield genuinely different, genuinely defensible accounts.

📚 A Shared Foundation for HIST 101 and HIST 102

This unit belongs to both survey courses. The skills are the same whether you are reading about the Stamp Act or the Cold War, so rather than teach them twice, they live here — in one place, available to every section, and worth returning to whenever a reading assignment asks you to weigh an interpretation rather than just absorb it. The examples come from the Revolutionary era because it is the case both courses can assume, not because historiography is a colonial-era problem.

The Three Lectures

Each deck is a full presentation you can page through at your own pace, with pause-and-reflect prompts, expandable explanations, and independent-study material at the end.

Lecture One

What Is History?

Anchor case: two accounts of one night on King Street

Two witnesses to the Boston Massacre agree on almost everything — the date, the street, the officer, the crowd, the dead — and still tell irreconcilable stories. Working out why introduces the difference between the past and history, and the toolkit historians use to move from evidence to argument.

  • The past vs. history: two different things
  • The five moves historians make
  • The five historical-thinking questions
  • Primary and secondary sources
  • Why "primary" does not mean "unbiased"
Open Lecture One
Lecture Two

What Makes History Happen?

Anchor case: Boston, 14 August 1765

A crowd destroys a stamp distributor's property, and within twelve days the office is vacant. Who actually made that happen? Testing the obvious answers against the evidence turns into a working lesson on causation, agency, and the difference between what came before an event and what produced it.

  • What a causal claim actually requires
  • Agency: nine men and a shoemaker
  • Structure: crowd traditions, debt, depression
  • Contingency and the trouble with hindsight
  • Three lenses — what each reveals and hides
Open Lecture Two
Lecture Three

Why Do Historians Disagree?

Anchor case: three readings of the Revolution

Disagreement among historians is not a scandal or a sign that the field is broken — it is what a healthy discipline looks like when scholars ask different questions of the same evidence. This lecture shows how to compare rival interpretations fairly and judge them by shared standards.

  • Why disagreement is normal, not relativism
  • The Progressive reading (Beard)
  • The ideological reading (Bailyn)
  • The continental reading (Taylor)
  • Objectivity as a practice, not a pose
Open Lecture Three

The Historian's Toolkit

Two frameworks run through all three lectures and through the rest of both courses. Keep them straight: one is the process, the other is what you ask the evidence at every stage of it.

The Five Moves

The workflow — how an account gets produced

Ask a question Find sources Evaluate them Interpret the evidence Construct and defend

The Five Questions

The toolkit — what you ask the evidence

  1. Cause — why did this happen, and by what mechanism?
  2. Comparison — how do two cases differ, judged on the same basis?
  3. Context — what world made this action make sense?
  4. Consequence — what changed, for whom, over how long?
  5. Evidence — what supports the claim, and is it enough?
