United States History
What this domain tests
US History questions ask you to connect major eras-encounter and colonization, Revolution and Constitution, expansion and sectionalism, Civil War and Reconstruction, industrialization and immigration, Progressive reform, the Depression and New Deal, world wars and the Cold War, civil rights, and recent political realignment-through evidence and causation.
Core rules
- Periodize by turning points, not dates alone. 1877, 1898, 1933, 1945, 1954, and 1964 matter because they mark changed rules or coalitions.
- Explain causation with multiple factors. The Civil War grew from slavery's expansion, sectional political economy, and constitutional disagreement; a single-cause answer is weak.
- Track federal power. The 13th–15th Amendments, New Deal programs, and civil rights statutes each expanded federal authority in different ways.
- Include ordinary people. Labor, migration, women, Native nations, and African Americans shape outcomes; top-down narratives miss evidence.
- Read founding documents as arguments. The Constitution reflects compromises over representation, slavery, and federalism.
Worked example
Prompt: Evaluate the claim that Reconstruction failed. Evidence: the 13th, 14th, and 15th Amendments; Freedmen's Bureau records; Black Codes; the Compromise of 1877; and testimony from formerly enslaved people. Reasoning: constitutional change was durable, but enforcement collapsed as federal troops withdrew and white supremacist violence and law narrowed Black political power. A strong response separates short-term political failure from long-term constitutional legacy, and it cites specific evidence rather than labeling the era.
Traps
Calling the Civil War about states' rights without explaining which rights; confusing the 14th and 15th Amendments; treating Reconstruction as only a southern story; assuming wartime unity on the home front; and using the word inevitable instead of analyzing contingency.
