Jun 13, 2025

Overview

This lecture reviewed APUSH Units 1-5, covering early Native American societies, European colonization, the American Revolution, the emergence of the U.S. government, antebellum reforms, and the Civil War through Reconstruction. Key concepts, turning points, and exam-relevant developments were highlighted.

Unit 1: 1491–1607 (Native Societies and European Contact)

  • Native Americans had diverse societies shaped by regional environments (e.g., Chumash, Ute, Cahokia, Iroquois).
  • European exploration was driven by trade routes, wealth, and spreading Christianity.
  • The Columbian Exchange transferred crops, animals, and diseases between the Old and New Worlds.
  • Spanish colonization led to systems like encomienda, rise of African slavery, and the casta system of racial hierarchy.
  • Interactions led to changes in European and Native American worldviews; debates over treatment (de Sepúlveda vs. Las Casas).

Unit 2: 1607–1754 (Colonial America)

  • Spanish, French, Dutch, and English colonization had distinct goals (gold, trade, religious freedom, land).
  • British colonies differed: Chesapeake (tobacco, indentured slaves), New England (religious, family), Middle (trade, diversity), Southern (cash crops, slavery).
  • Self-governing traditions emerged (Mayflower Compact, House of Burgesses).
  • Triangular trade and mercantilism linked colonies to global economy.
  • Conflicts with Native Americans (Metacom’s War, Pueblo Revolt); European policies varied by region.
  • Slavery became central, especially in the South; resistance included covert culture and open revolt (Stono Rebellion).
  • Enlightenment and First Great Awakening shaped colonial identity.
  • British policies (e.g., impressment) increased colonial mistrust.

Unit 3: 1754–1800 (Revolution and New Nation)

  • French and Indian War expanded British land but increased colonial taxation, fueling discontent.
  • Salutary neglect ended; colonists resented taxes without representation.
  • Enlightenment ideas influenced independence (Common Sense, Declaration of Independence).
  • Patriots won the Revolution due to leadership, French aid, and British weaknesses.
  • The Articles of Confederation created a weak government; events like Shays’ Rebellion exposed flaws.
  • The Constitution introduced federalism, separation of powers, and compromises (Great Compromise, 3/5 Compromise, Bill of Rights).
  • Revolutionary ideals sparked debates on slavery (emancipation in North), women’s roles (Republican Motherhood), and inspired other revolutions (France, Haiti).
  • Washington and Adams set precedents on party politics, economic, and foreign policy; conflicts over state vs. federal authority (Whiskey Rebellion, Alien/Sedition Acts).
  • American cultural identity grew in arts, literature, and architecture.

Unit 4: 1800–1848 (Antebellum America)

  • Party debates (Federalists vs. Democratic-Republicans) and strict vs. loose constitutional interpretation.
  • Louisiana Purchase doubled U.S. territory; Supreme Court gained power (Marbury v. Madison).
  • Regional tensions grew (War of 1812, Missouri Compromise, American System).
  • Monroe Doctrine asserted U.S. dominance in the Western Hemisphere.
  • Market Revolution: transportation/industrial innovations linked regions, increased immigration, and created a middle class.
  • Expansion of democracy: universal white male suffrage, new political parties (Democrats, Whigs).
  • Jackson’s presidency used federal power (Tariff of Abominations, Bank War, Indian Removal).
  • Reform movements: abolitionism (Garrison, Turner), temperance, women’s rights (Seneca Falls Convention, Declaration of Sentiments).
  • Southern society centered on agriculture and slavery, even among non-slaveholders.

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

  • Manifest Destiny justified westward expansion (Preemption Acts, Gold Rush, need for land).
  • Mexican-American War (from Texas annexation) led to large land gains; disputes over slavery in new territories (Wilmot Proviso).
  • Compromise of 1850 temporarily eased sectional tensions (popular sovereignty, fugitive slave law).
  • Immigrant waves created ethnic enclaves and nativist backlash (Know-Nothing Party).
  • Sectional labor differences and abolitionist movement (Underground Railroad, Uncle Tom’s Cabin) heightened tensions.
  • Compromises failed (Kansas-Nebraska Act, Bleeding Kansas, Dred Scott case), leading to sectional political parties.
  • Lincoln’s 1860 election triggered Southern secession and the Civil War (Confederate States of America).
  • The North’s strategic advantages and shifting war aims (Emancipation Proclamation, Gettysburg Address) led to Union victory.
  • Reconstruction brought the 13th, 14th, and 15th Amendments, federal occupation of the South, and debates over reintegration.
  • Reconstruction ultimately failed due to Southern resistance (sharecropping, black codes, KKK), Northern fatigue, and the Compromise of 1877.
