AP US History Evidence Bank: Specific Examples by Period for the LEQ and DBQ

The evidence points on the DBQ and LEQ reward specific facts used to support a claim, not names dropped in passing. Use this table to build a short bank of dated, concrete examples for each period. For each one, be ready to say what it was, when it happened, and which claim it proves.

How to use the bank

  • Learn two or three examples for each period, not all of them.
  • For each, practice a one-sentence description: what happened, when, and the effect.
  • Match each to an argument. Evidence is only useful in an essay when it supports a claim.

Turning an example into evidence

Does not earn the pointThe Erie Canal was important to the economy.

It names the example but says nothing specific about what it did.

Earns the pointThe Erie Canal, opened in 1825, linked the Great Lakes to the Hudson River and sharply lowered the cost of shipping grain to New York City, so it tied western farms to eastern markets and helped the Market Revolution spread.

It describes the example, dates it, and ties it to the argument.

Common mistakes

  • Naming a law or case with no description of what it did.
  • Using the same one or two examples for every prompt.
  • Choosing evidence from outside the period named in the prompt.
  • Memorizing dates without learning the effect.

Frequently asked questions

How many examples should I memorize for each period?

Two or three that you can describe in a sentence are better than ten you can only name.

Does evidence have to be from the exact years of the prompt?

It should fit the time frame of the prompt, and evidence from just before or after can serve as context.

Can I use the same example in different essays?

Yes, if it supports the claim in each. Evidence is judged by how well it supports your argument.

Is this list complete?

No. It is a starting bank. Build your own from the lessons.

Where can I find the official scoring rules?

Exam formats change a little from year to year, so check the current course and exam description on the College Board site before test day.
