What Is a Historical Document?

A historical document is any written, printed, or recorded item that gives us information about the past. These are the raw materials historians use to reconstruct events, ideas, and daily life.

Two Source Types

PRIMARY Created at the time by a witness Diaries Speeches Treaties SECONDARY Made later, after studying the event Textbooks Biographies Documentaries vs

Why Analysis Matters

Reading a document is not the same as analyzing it. Analysis means asking questions about the source to uncover meaning, purpose, and reliability.

Context
Understand the time period and events surrounding the document.
Purpose
Figure out why the author created it and who it was meant for.
Bias
Detect the author's point of view and possible slant.

The Core Rule: SOAPS

A reliable framework for analyzing any document is SOAPS. Work through each letter to break a source down into its essential parts.

S Speaker O Occasion A Audience P Purpose S Subject Five questions that unlock any historical source

SOAPS, Explained

S
Speaker. Who created the document? What do we know about them?
O
Occasion. What event or situation prompted the document?
A
Audience. Who was meant to read or hear it?
P
Purpose. What was the author trying to achieve?
S
Subject. What is the main idea or topic of the document?

Fact vs. Opinion

A crucial skill is separating verifiable facts from the author's opinions. Documents often blend both, and recognizing the difference reveals bias.

Fact
Can be proven true or false. "The treaty was signed in 1783."
Opinion
A belief or judgment. "The treaty was unfair to the colonists."

How to Apply It

1
Read the source line. Note the author, date, and title before reading the body.
2
Identify the type. Is it primary or secondary? Fact or opinion?
3
Apply SOAPS. Answer each of the five questions about the document.
4
Connect to the era. Tie the document to its historical context.
5
Draw a conclusion. Decide what the source tells you and how reliable it is.

Example 1: A Famous Line

Type
Primary source, written at the time of the event.
Purpose
To justify independence from Britain to the world.
Audience
The British Crown, colonists, and foreign nations.

Example 2: Spotting Bias

1
Loaded words: "reckless," "unjust," "crushing" signal strong opinion.
2
Purpose: to persuade colonists to oppose the king, not to report neutrally.
3
Reliability: useful for understanding colonial anger, but heavily biased.

Example 3: Reading a Chart

Documents also include data and statistics. For example, the colonial population roughly doubled every 25 years. If it grew from 1.2 million to 2.4 million, the growth factor is \( \frac{2.4}{1.2} = 2 \), or a 100% increase.

2.4M 1.2M 0 1725 1750 1775 0.5M 1.2M 2.4M Colonial Population Growth (Approx.)

Common Mistakes

✕ Ignoring the source line
Skipping the author and date loses the context that shapes meaning.
✕ Treating opinion as fact
Accepting a biased claim as objective truth leads to wrong conclusions.
✕ Forgetting the era
Judging a document by today's standards instead of its own time.
✕ Trusting one source
Relying on a single document without cross-checking others.

Key Takeaways

1
Identify the source type — primary or secondary — before analyzing.
2
Use SOAPS to break down Speaker, Occasion, Audience, Purpose, and Subject.
3
Separate fact from opinion and watch for loaded language and bias.
4
Cross-check sources and place each document in its historical era.

You're Ready to Analyze

You now know how to question any historical document, identify its type, detect bias, and connect it to its era. Apply SOAPS to every source you read.
