APUSH notes are only useful if they're compressed. A textbook chapter runs 40 pages; the exam wants you to hold the essence of that chapter in your head. This article is a compressed set of notes, unit by unit, that you can revise from directly in the last few weeks before the exam.

Use it as a checklist: For each unit, can you explain the events listed in 2-3 sentences? If not, that's where to dig in with your textbook or Cognito's APUSH notes.


Unit 1 (1491-1607): Contact and exchange

Diverse Native societies before Columbus: Puebloan agriculturalists in the Southwest, Mississippian mound-builders, Iroquois confederacies, Northwest fishing peoples. Columbus reaches the Caribbean in 1492. Columbian Exchange transfers crops (maize, potato, tomato out; wheat, sugar, coffee in), animals (horse, cattle, pig) and diseases (smallpox, measles) between hemispheres. Spanish encomienda system exploits Native labor; Spanish colonies develop a racial caste (casta) system (mestizo, mulatto). Native population collapses by 80-90% in Spanish America within a century.

Chesapeake and Southern colonies build plantation economy: Indentured servitude gives way to chattel slavery after Bacon's Rebellion (1676) exposes risks of poor-white and enslaved-Black alliances. Middle Colonies (Pennsylvania, New York) diverse and commercial. New England towns run on Congregational church and town meetings. First Great Awakening (1730s-40s) with Whitefield and Edwards spreads emotional evangelical religion across colonies. Enlightenment ideas (Locke, natural rights) circulate among educated colonists. Salutary neglect: Britain leaves colonies largely self-governing until 1760s.

Second Great Awakening fuels reform movements: Abolition (Garrison, Douglass, Grimke sisters), women's rights (Seneca Falls Convention 1848 with Declaration of Sentiments), temperance, education (Horace Mann), asylum reform (Dorothea Dix). Transcendentalism (Emerson, Thoreau).


Unit 5 (1844-1877): Civil War and Reconstruction

Compromise of 1850: California free, Fugitive Slave Act, popular sovereignty for territories. Kansas-Nebraska Act (1854) repeals Missouri Compromise, triggers Bleeding Kansas. Dred Scott (1857) rules Congress can't ban slavery in territories. John Brown's raid on Harpers Ferry (1859). Lincoln elected (1860), 7 states secede before inauguration. Civil War (1861-65): Anaconda Plan, Antietam (Sept 1862) enables Emancipation Proclamation (Jan 1863), Gettysburg and Vicksburg (July 1863) turn tide, Sherman's March, Appomattox (April 1865), Lincoln assassination.
