United States History
What the domain tests
United States history questions test periodization, causation, and the relationship between ideals and practice. Know colonial development and the Revolution; the Articles of Confederation and the Constitution; federalism and sectionalism; westward expansion; the Civil War and Reconstruction; industrialization and immigration; Progressivism; the New Deal; World War II; the civil rights movement; the Cold War; and modern political realignment.
Concepts to connect
Trace how debates over slavery, federal power, and citizenship shaped the Constitution and the sectional crisis. The Civil War's central cause was slavery, though questions may ask about specific triggers such as secession or Fort Sumter. Reconstruction's Thirteenth, Fourteenth, and Fifteenth Amendments expanded freedom, citizenship, and voting rights, but black codes, violence, and withdrawal of federal troops limited enforcement. Industrialization created new corporate forms, labor conflict, and reform movements. The New Deal expanded federal responsibility but did not fully end the Depression; wartime spending did.
Traps
Watch for answers that confuse the Articles with the Constitution, attribute the New Deal's recovery entirely to one program, or treat the civil rights movement as a single spontaneous event. Avoid 'always/never' claims. Distinguish legal change from lived change. Questions asking 'most immediate' or 'primary' require a direct link, not a general trend.
Worked example and rule of thumb
Prompt: 'Which development most directly expanded federal power in the 1930s?' Social Security and New Deal regulatory agencies are stronger than 'the automobile' or 'World War I,' which are true background but not direct. Rule of thumb: identify the turning point, then ask which answer is both chronologically possible and causally close. If it predates the prompt or is only loosely related, eliminate it.
