4.1 Contextualizing Period 4
Overview
Period 4 (1800–1848) witnessed the transformation of the United States from a fragile republic into an expanding nation characterized by democratic ideals, territorial growth, economic revolution, and intensifying sectional divisions. This era saw the consolidation of American democracy, the explosive growth of the Market Revolution, westward expansion driven by Manifest Destiny, and the rise of social reform movements—all while the nation grappled with the contradiction between democratic ideals and the reality of slavery.
The period begins with the "Revolution of 1800"—the peaceful transfer of power from Federalists to Democratic-Republicans—and ends on the eve of the Mexican-American War's conclusion and the intensifying sectional crisis over slavery's expansion.
🎯 Key Themes
- Democratic Expansion: Voting rights extended to all white men; Jacksonian Democracy
- Market Revolution: Transportation improvements, industrialization, commercial agriculture transformed economy
- Territorial Expansion: Louisiana Purchase doubled nation's size; Manifest Destiny ideology justified westward movement
- Reform Movements: Second Great Awakening inspired abolitionism, temperance, women's rights, education reform
- Sectional Tensions: North vs. South divisions over slavery, tariffs, internal improvements
- Native American Removal: Indian Removal Act, Trail of Tears displaced eastern tribes
⚠️ AP Exam Context
- Period 4 carries 10–17% exam weight—equal to Periods 3 and 5
- Heavy emphasis on comparison: North vs. South, Jeffersonian vs. Jacksonian democracy
- Understand causation: Market Revolution → social change; territorial expansion → sectional crisis
- Key skills: Analyze how democratic ideals expanded for some while excluding others
4.2 The Rise of Political Parties and the Era of Jefferson (PCE)
Election of 1800: "Revolution of 1800"
Candidates: Thomas Jefferson (Democratic-Republican) vs. John Adams (Federalist)
Campaign: Bitter, partisan; Federalists accused Jefferson of atheism; Republicans attacked Adams as monarchist
Electoral College Tie: Jefferson and running mate Aaron Burr tied; House of Representatives decided (Hamilton supported Jefferson despite enmity)
Outcome: Jefferson won; first peaceful transfer of power between parties
Significance: Proved democratic system worked; led to 12th Amendment (1804)—separate electoral votes for president and vice president
Jefferson's Presidency (1801–1809)
Jeffersonian Philosophy
- Agrarian Republic: Vision of independent farmers; opposed Hamilton's commercial/industrial economy
- Limited Government: Strict construction of Constitution; states' rights
- Reduced Federal Power: Cut military, eliminated internal taxes, reduced national debt
- Expansion: Believed westward expansion essential for agrarian republic
Louisiana Purchase (1803) — MAJOR ACHIEVEMENT
Background: France regained Louisiana from Spain (1800); Jefferson feared French control of New Orleans (vital port for Western farmers)
Opportunity: Napoleon needed money for European wars; offered to sell entire Louisiana Territory
Purchase: U.S. bought ~827,000 square miles for $15 million (~3 cents per acre)
Constitutional Dilemma: Constitution didn't explicitly authorize land purchases; Jefferson (strict constructionist) had to use loose construction to justify
Lewis and Clark Expedition (1804–1806): Meriwether Lewis and William Clark explored Louisiana Territory; reached Pacific; mapped territory; established relations with Native tribes
Significance: Doubled U.S. size; secured Mississippi River and New Orleans; opened West to expansion; set precedent for continental expansion
Marbury v. Madison (1803) — JUDICIAL REVIEW
Background: Adams appointed "midnight judges" before leaving office; Jefferson's Secretary of State Madison refused to deliver some commissions
Case: William Marbury sued for his commission
Chief Justice: John Marshall (Federalist appointed by Adams)
Ruling: Marshall declared section of Judiciary Act of 1789 unconstitutional
Significance: Established judicial review—Supreme Court's power to declare laws unconstitutional; strengthened judicial branch; Marshall Court dominated for decades
Foreign Policy Challenges
Barbary Wars (1801–1805): U.S. fought North African pirates demanding tribute; showed willingness to protect trade
Embargo Act (1807):
- Cause: Britain and France at war; both seized U.S. ships; British impressment (forcing American sailors into British navy)
- Policy: Jefferson banned all foreign trade to avoid war
- Impact: Devastated American economy (especially New England merchants); smuggling rampant; repealed 1809
- Significance: Demonstrated limits of "peaceful coercion"; led to War of 1812

- Naval Victories: USS Constitution ("Old Ironsides") won battles on Great Lakes
- British Burned Washington D.C. (1814): Retaliation for U.S. burning York (Toronto)
- Fort McHenry: British failed to take Baltimore; inspired "Star-Spangled Banner"
- Battle of New Orleans (1815): Andrew Jackson's victory (fought after peace treaty signed but before news arrived)
Hartford Convention (1814): New England Federalists met to protest war; proposed constitutional amendments; looked treasonous after war ended; destroyed Federalist Party
Treaty of Ghent (1814): Ended war; restored pre-war boundaries; didn't address impressment or other causes; essentially a draw
Results
- National Pride: "Second War of Independence"; confirmed U.S. sovereignty

President: James Monroe (1817–1825)
Reality: Name misleading—underneath surface unity, sectional tensions growing over slavery, tariffs, internal improvements
Missouri Compromise (1820) — FIRST MAJOR SECTIONAL CRISIS
Issue: Missouri applied for statehood as slave state; would upset balance (11 free, 11 slave states)
Northern Opposition: Didn't want slavery to expand; feared Southern political power
Southern Defense: Claimed right to bring property (enslaved people) into territories
Compromise (Henry Clay):
- Missouri: Admitted as slave state
- Maine: Admitted as free state (from Massachusetts) to maintain balance
- 36°30' Line: Slavery banned in Louisiana Purchase north of this line (except Missouri)
Significance: Temporarily resolved crisis; revealed deep sectional divisions; Thomas Jefferson called it "a fire bell in the night"—warning of future conflict

- 36°30' Line: Dividing line between free and slave territories in Louisiana Purchase
⚠️ AP Exam Tips
- War of 1812: Know causes, key events, and results; understand regional divisions
- Missouri Compromise: First major sectional crisis over slavery expansion; know all terms
- Irony: "Era of Good Feelings" masked growing sectional tensions
- Hartford Convention: Example of regional opposition; ended Federalist Party
4.4 America on the World Stage (WOR)

Main Points:
- Non-Colonization: Western Hemisphere closed to new European colonization
- Non-Intervention: Europe should not interfere in independent American nations
- Non-Involvement: U.S. would not interfere in European affairs or existing colonies
- Protection: U.S. would view European intervention in Americas as threat to national security
Authored By: Secretary of State John Quincy Adams (though announced by Monroe)
Significance: Asserted U.S. role as protector of Western Hemisphere; couldn't be enforced (weak military) but British navy backed it; became cornerstone of U.S. foreign policy; later used to justify American interventions
Territorial Expansion
Adams-Onís Treaty (1819)
Also Called: Transcontinental Treaty
Terms: Spain ceded Florida to U.S.; defined western boundary of Louisiana Purchase to Pacific Ocean
Context: Andrew Jackson had invaded Florida (1818) chasing Seminole; Spain couldn't control Florida

4.5 Market Revolution: Industrialization (WXT)
Overview of Market Revolution
The Market Revolution (1800s–1840s) transformed the U.S. from a subsistence, agrarian economy to a national market economy driven by technological innovation, transportation improvements, and industrial growth. This revolution fundamentally changed how Americans worked, lived, and related to one another.
Transportation Revolution
Roads
National Road (Cumberland Road): First federally funded road (1811); connected Maryland to Illinois; facilitated westward migration
Turnpikes: Private toll roads improved travel but were expensive
Canals
Erie Canal (1825): Connected Great Lakes to Hudson River/Atlantic Ocean
- 363 miles long; engineering marvel
- Reduced shipping costs by ~90%; travel time from 20 days to 6 days
- Made New York City dominant commercial center
- Sparked canal-building boom across nation
- Connected Western farmers to Eastern markets
Impact: Transformed regional economies; made agricultural goods cheaper; encouraged settlement of Midwest
Steamboats
Robert Fulton's Clermont (1807): First commercially successful steamboat
Impact:
- Revolutionized river travel—could travel upstream against current
- Transformed Mississippi River into commercial highway
- Connected interior to coastal markets
- Reduced shipping costs and travel time dramatically
Railroads
Early Development: 1830s–1840s; initially short lines connecting cities
Advantages: Faster than canals; not limited by geography or freezing; operated year-round
Impact: By 1850s, railroads surpassed canals; transformed economy; connected distant markets
Industrialization
Textile Industry
Samuel Slater (1790): "Father of American Industrial Revolution"; memorized British textile machinery designs; built first water-powered cotton mill in Rhode Island
Lowell System (1820s):
- Textile mills in Lowell, Massachusetts
- Employed young, unmarried women ("Lowell Girls") from farms
- Provided housing in boardinghouses with strict rules
- Initially offered good wages and conditions; deteriorated over time
- Women gained economic independence but faced difficult working conditions
Significance: Transformed textile production from home-based to factory system; established pattern for American industrialization
Interchangeable Parts

Cult of Domesticity (Separate Spheres)
Ideology: Middle-class idea that men and women occupied separate spheres
- Men's Sphere: Public—work, politics, business
- Women's Sphere: Private—home, children, moral guardianship
Four Virtues: Piety, purity, submissiveness, domesticity
Reality: Applied primarily to middle/upper-class white women; working-class and enslaved women couldn't afford domesticity
Consequence: Limited women's opportunities but also gave them moral authority used in reform movements
Immigration
Irish Immigration (1840s):
- Cause: Potato Famine (1845–1852) devastated Ireland
- Numbers: Over 1 million Irish immigrated

4.7 Expanding Democracy (PCE)
Expansion of Suffrage
1820s–1830s: Property requirements for voting eliminated in most states
Universal White Male Suffrage: Nearly all white men could vote by 1840s regardless of property ownership

- Worcester v. Georgia (1832): Supreme Court (Chief Justice Marshall) ruled Cherokee nation sovereign; Georgia laws didn't apply
- Jackson's Response: Allegedly said "Marshall has made his decision, now let him enforce it" (disputed); refused to enforce ruling
Trail of Tears (1838):
- Forced march of Cherokee to Oklahoma
- ~4,000 of 15,000 Cherokee died from disease, starvation, exposure
- Symbol of Native American suffering under U.S. expansion
