United States History
What the domain tests
United States History covers Indigenous societies and colonization through the present, with emphasis on causation, continuity and change, and the experiences of multiple groups.
Core rules
- Founding compromises: the Constitution blended the Virginia Plan (population-based representation), New Jersey Plan (equal state representation), and the Three-Fifths Compromise; the Bill of Rights was added to secure ratification.
- Federalism: power is shared between national and state governments; the Civil War and Reconstruction expanded national authority.
- Reconstruction amendments: the 13th abolished slavery; the 14th granted citizenship, due process, and equal protection; the 15th protected voting rights by race.
- Industrialization: railroads, immigration, and corporate consolidation produced growth alongside labor conflict and urban poverty.
- Civil rights: legal victories such as Brown v. Board (1954) and mass movements interacted; the Civil Rights Act of 1964 and Voting Rights Act of 1965 relied on enforcement.
Worked example
A prompt asks how Reconstruction changed federal-state relations. A strong response cites the 14th Amendment’s equal protection clause, the Freedmen’s Bureau, and federal enforcement acts, then notes the retreat after 1877 as a limit. It distinguishes constitutional change from practice.
Traps
Confusing the Declaration of Independence (1776) with the Constitution (1787); treating Reconstruction as only a southern story; accepting “states’ rights” language without asking whose rights; assuming a law’s passage ended discrimination.
