What to Know

  • Use specific evidence to support a defensible historical claim.
  • Organize DBQ and LEQ evidence around an argument.
  • Show complexity with multiple causes, competing perspectives, or qualified change over time.
  • Always connect this topic back to the larger unit: Period 5: 1844-1877.

Detailed Notes

Manifest Destiny should be studied as part of a larger historical process. Ask what came before, what changed, who was affected, and what evidence proves it.

In AP United States History, dates and names matter most when they support an argument. Tie specific facts to themes such as power, economics, culture, migration, technology, or social structure.

For AP writing, turn the topic into a claim. Then use evidence to explain causes, effects, comparisons, or continuities instead of simply narrating events in order.
