AP US History (APUSH): Complete Guide
All 9 periods, all 7 themes, DBQ and LEQ rubrics, and the historical-thinking skills the College Board actually tests.
1: 1491–1607
Pre-Columbian America and European contact
Period 1 establishes Native societies as diverse and complex — Pueblo agriculturalists in the Southwest, Mississippian mound-builders, Iroquoian Confederacy, Pacific Northwest fishing societies. Columbus's 1492 voyage triggered the Columbian Exchange: bidirectional transfer of crops, animals, people, and diseases between hemispheres. Spanish encomienda labor and Catholic missionization defined the first century of European-Indigenous contact.
Key Points
- Columbian Exchange: corn, potatoes, tomatoes, tobacco eastward; horses, cattle, pigs, smallpox westward.
- Encomienda system: Spanish crown grants of Indigenous labor; replaced over time by African chattel slavery.
- Spanish caste system (peninsulares → criollos → mestizos → mulattoes → Indigenous → enslaved Africans).
- Pueblo Revolt (1680) — one of the most successful Indigenous resistances in colonial history.
2: 1607–1754
Colonial regions and slavery
Three distinct regional patterns emerged: the Chesapeake (tobacco, indentured servitude shifting to slavery after Bacon's Rebellion in 1676), New England (Puritan town governance, mixed agriculture, shipping), and the Middle Colonies (religious and ethnic diversity, grain). The transatlantic slave trade — roughly 12.5 million Africans forcibly transported across the Middle Passage, with ~388,000 arriving directly in British North America — became the foundation of plantation economies in the South.
Key Points
- Mayflower Compact (1620), Fundamental Orders of Connecticut (1639) — early self-government compacts.
- Bacon's Rebellion (1676) accelerated the racialization of slavery.
- Salutary neglect: British laissez-faire administration prior to 1763.
- Great Awakening (1730s–40s) — Edwards, Whitefield; introduced ideas of individual religious authority that fed revolutionary thought.
3: 1754–1800
Revolution and Constitution
The French and Indian War (1754–63) saddled Britain with debt and ended salutary neglect. Stamp Act, Townshend Acts, Tea Act, and the Intolerable Acts radicalized colonial elites. Common Sense (Paine, 1776) and the Declaration of Independence (Jefferson, 1776) framed independence in Enlightenment terms. After the Articles of Confederation proved unworkable (Shays' Rebellion, 1786), the 1787 Constitutional Convention produced the federal Constitution.
Key Points
- Battles of Lexington and Concord (April 1775), Saratoga (1777, French alliance turning point), Yorktown (1781).
- Treaty of Paris (1783) recognized US independence with generous boundaries.
- Connecticut, Three-Fifths, and Commerce Compromises produced the Constitution.
- Federalists vs Anti-Federalists; Bill of Rights (1791) secured ratification.
- Washington's Farewell Address warned against permanent alliances and factionalism.
4: 1800–1848
Early Republic and Jacksonian democracy
Jefferson's election (1800) was the first peaceful partisan transfer in US history. The Louisiana Purchase (1803) doubled US territory; Marbury v Madison (1803) established judicial review. The War of 1812 ended the Federalist Party. Jacksonian democracy expanded the franchise to most white men but used the Indian Removal Act (1830) to displace southeastern Native nations via the Trail of Tears. The Market Revolution, Second Great Awakening, and antebellum reform movements (abolition, temperance, women's rights at Seneca Falls in 1848) reshaped society.
Key Points
- Era of Good Feelings (1817–25) — temporary single-party dominance under Monroe.
- Missouri Compromise (1820) — temporary settlement of slavery's expansion.
- Monroe Doctrine (1823) — Western Hemisphere closed to further European colonization.
- Nullification Crisis (1832–33) — South Carolina vs Jackson over tariffs; preview of secession.
- Seneca Falls Declaration (1848) modeled on Declaration of Independence.
5: 1844–1877
Manifest Destiny, Civil War, Reconstruction
Mexican-American War (1846–48) added the Southwest and intensified sectional conflict. Compromise of 1850, Kansas-Nebraska Act (1854), Dred Scott (1857), and Lincoln's 1860 election triggered Southern secession. The Civil War (1861–65) killed an estimated 620,000–750,000 Americans. Emancipation Proclamation (1863), 13th-15th Amendments, Freedmen's Bureau, and Radical Reconstruction restructured citizenship — but the Compromise of 1877 ended federal enforcement, and Jim Crow followed.
Key Points
- Antietam (1862) → Emancipation Proclamation; Gettysburg + Vicksburg (1863) — turning points.
- 13th (abolition), 14th (citizenship + Equal Protection), 15th (Black male suffrage) — Reconstruction Amendments.
- Black Codes, KKK, sharecropping reasserted racial hierarchy.
- Compromise of 1877 ended Reconstruction in exchange for Hayes presidency.
6: 1865–1898
Gilded Age, industrialization, the West
Rapid industrialization produced Carnegie (steel), Rockefeller (oil), and Morgan (finance). Labor responded with the Knights of Labor, AFL, Homestead (1892) and Pullman (1894) strikes. The Dawes Act (1887) broke up tribal lands. New immigration from Southern and Eastern Europe filled urban tenements; Chinese Exclusion Act (1882) was the first major federal immigration restriction. Populist movement (Omaha Platform, 1892; Bryan's 1896 'Cross of Gold' speech) channeled agrarian discontent.
Key Points
- Vertical integration (Carnegie) vs horizontal integration (Rockefeller).
- Sherman Antitrust Act (1890) — initially used more against unions than trusts.
- Plessy v Ferguson (1896) — 'separate but equal' constitutional for six decades.
- Frederick Jackson Turner's Frontier Thesis (1893) reframed American identity.
7: 1890–1945
Progressive Era to WWII
Progressives (T. Roosevelt, Wilson) regulated trusts, banking (Federal Reserve, 1913), and food/drug safety. Imperial expansion (Spanish-American War, 1898; Philippines) and WWI (1917–18) marked America's global emergence. The 1920s saw mass consumption, the Harlem Renaissance, Prohibition, and the Great Migration. The 1929 stock market crash launched the Great Depression; FDR's New Deal (1933–38) restructured the federal role. WWII (1941–45) mobilized the entire economy; Japanese internment, the Manhattan Project, and Hiroshima/Nagasaki defined its moral legacy.
Key Points
- 16th (income tax), 17th (direct senatorial election), 18th (Prohibition), 19th (women's suffrage) Amendments — all Progressive-era.
- Schenck v US (1919) — 'clear and present danger' during WWI dissent.
- New Deal: 3 R's — Relief, Recovery, Reform; Social Security (1935) is the most durable legacy.
- Lend-Lease (1941), Pearl Harbor (Dec 7, 1941) → US entry; D-Day (June 6, 1944); VE Day (May 1945); VJ Day (Aug 1945).
- Bretton Woods (1944) and the UN (1945) restructured the postwar international order.
8: 1945–1980
Cold War, civil rights, the 60s
Containment (Kennan's Long Telegram, Truman Doctrine, Marshall Plan, NATO) shaped foreign policy. Korea (1950–53), Cuban Missile Crisis (1962), Vietnam (escalation 1964–73). Domestic Cold War: McCarthyism, HUAC. Civil Rights Movement: Brown (1954), Montgomery Bus Boycott (1955–56), SCLC + SNCC, March on Washington (1963), Civil Rights Act (1964), Voting Rights Act (1965). Great Society programs (Medicare, Medicaid, ESEA). 1970s: Watergate (Nixon resigns, 1974), stagflation, energy crisis.
Key Points
- Truman Doctrine + Marshall Plan = containment + reconstruction.
- Letter from Birmingham Jail (1963) articulated nonviolent direct action's moral case.
- Roe v Wade (1973); Title IX (1972); ERA passed Congress 1972 but never ratified.
- OPEC oil embargo (1973) exposed US economic vulnerability.
- Iran Hostage Crisis (1979–81) ended Carter's presidency.
9: 1980–Present
Reagan to today
Reagan Revolution: supply-side tax cuts, deregulation, military buildup. Cold War ended (Berlin Wall 1989, USSR dissolved 1991). 1990s globalization (NAFTA, WTO) and the dot-com economy. 9/11 (2001) triggered the War on Terror, Afghanistan, and Iraq. 2008 financial crisis → Obama presidency, Dodd-Frank, ACA (2010). Polarization, social media, the 2016 election, COVID-19 (2020), and Dobbs (2022) define recent history. AP requires you to use evidence from the period without being graded on contemporary political opinions.
Key Points
- Reagan + Volcker Fed broke inflation by 1983 at the cost of severe 1981–82 recession.
- NAFTA (1994), WTO (1995), China WTO accession (2001) defined globalization.
- Bush v Gore (2000) decided a presidential election in the Supreme Court.
- USA PATRIOT Act (2001) expanded surveillance authorities.
- Citizens United (2010), Obergefell (2015), Dobbs (2022) marked major doctrinal shifts.
7 Themes
The seven CED themes
Every APUSH question is anchored to at least one theme. Memorize the abbreviations — they appear on the rubric and in skills guides.
Key Points
- NAT — American and National Identity: how citizenship, race, and ideology have been contested.
- WXT — Work, Exchange, and Technology: labor systems, capitalism, technological change.
- MIG — Migration and Settlement: immigration, internal migration, frontier, urbanization.
- PCE — Politics and Power: parties, ideologies, reform, federal-state relations.
- WOR — America in the World: diplomacy, trade, war, imperialism.
- GEO — Geography and the Environment: how land use and ecology shaped policy and life.
- SOC — Culture and Society: religion, gender, race, art, mass culture.
DBQ Rubric (7 pts)
Document-Based Question scoring
The DBQ is worth 25% of the exam. You get 15 minutes reading + 45 minutes writing for one DBQ + one LEQ. Use at least four documents to support your argument, and include one outside piece of evidence. The 7-point rubric is non-negotiable — points are awarded for specific moves.
Key Points
- Thesis (1 pt): Defensible, historically defensible, responds to all parts of the prompt.
- Contextualization (1 pt): Broader historical context relevant to the prompt (1-2 sentences before the thesis).
- Evidence — Documents (up to 2 pts): Use content of 3 documents for 1 pt; use 4 documents to support an argument for 2 pts.
- Evidence — Beyond Documents (1 pt): One specific piece of historical evidence outside the documents.
- Analysis — Sourcing (1 pt): For at least two documents, explain how POV, purpose, situation, or audience is relevant.
- Analysis — Complexity (1 pt): Demonstrate nuanced understanding (corroborate + qualify + modify).
LEQ Rubric (6 pts)
Long Essay Question scoring
The LEQ is 15% of the exam. You choose 1 of 3 prompts spanning different time periods. No documents — pure recall and analysis. Same thesis and contextualization expectations as the DBQ, but with two pieces of outside evidence instead of documents.
Key Points
- Thesis (1 pt): Defensible, responds to prompt.
- Contextualization (1 pt): Broader historical context.
- Evidence (2 pts): 1 pt for two pieces of specific evidence; 2 pts for using that evidence to support the argument.
- Analysis — Historical Reasoning (1 pt): Frame the response using the targeted reasoning process (causation, comparison, or continuity/change).
- Analysis — Complexity (1 pt): Nuanced argument with qualification, corroboration, or modification.
Thinking Skills
Four historical-thinking skills
The CED organizes everything around four reasoning processes. The LEQ specifies which one to use; the DBQ leaves it open.
Key Points
- Continuity and Change Over Time (CCOT): What stayed the same, what changed, and why?
- Comparison: Similarities and differences across regions, groups, or eras.
- Causation: Short- vs long-term causes and effects.
- Periodization: Why does the CED draw period boundaries where it does? Defend or challenge them.
