4.1-4.4

Revolution of 1800

  • Election of 1800: Thomas Jefferson (Democratic-Republican) defeated John Adams (Federalist).

  • It was called a “revolution” because it was the first peaceful transfer of power between opposing parties in U.S. history.

  • Federalists stepped down without violence → huge moment for democratic stability.

Jefferson’s Presidency

  • Tried to shrink the federal government, cut taxes, reduce the military.

  • Louisiana Purchase (1803): Doubled U.S. territory, bought from France. Even though Jefferson was a strict constructionist, he used loose interpretation of the Constitution to make the deal.

  • Lewis and Clark Expedition (1804–1806): Explored and mapped new lands.

🚫 Conflicts & Challenges

  • Marbury v. Madison (1803): Established judicial review — the Supreme Court can declare laws unconstitutional.

  • Embargo Act (1807): Stopped all U.S. trade to avoid war between Britain and France → hurt U.S. economy, especially New England merchants.


4.2 — The War of 1812 and Nationalism

Causes of the War

  • Impressment: British captured American sailors and forced them into service.

  • Trade restrictions: British blockades hurt American trade.

  • Frontier conflicts: British supported Native American resistance (like Tecumseh’s Confederacy) against U.S. expansion.

  • “War Hawks”: Southern and Western congressmen (like Henry Clay) wanted war to defend U.S. honor and expand territory.

🕊 Effects of the War

  • Treaty of Ghent (1814): Ended war — no territorial changes.

  • Battle of New Orleans (1815): Andrew Jackson became a national hero (even though it happened after the treaty).

  • Nationalism increased: People felt pride that the U.S. “beat” Britain again.

  • Federalist Party collapsed: They opposed the war and looked unpatriotic after the Hartford Convention.

🇺🇸 The “Era of Good Feelings” (1816–1824)

  • One political party (Democratic-Republicans) dominated under James Monroe.

  • But there were still regional tensions and economic issues (see 4.3).


4.3 — The Market Revolution and Economic Changes

💼 What It Was

A massive shift in how Americans produced, transported, and sold goods — roughly 1800–1840s.

🚂 Key Innovations

  • Transportation: Steamboats, canals (like Erie Canal), railroads → connected regions.

  • Communication: Telegraph improved long-distance communication.

  • Industrialization: Textile mills (like Lowell Mill System) employed young women; rise of wage labor.

  • Agriculture: Cotton gin (Eli Whitney) → made cotton super profitable → expansion of slavery in the South.

🌍 Effects

  • Regional specialization:

    • North: Industrial economy.

    • South: Cotton and slavery.

    • West: Food production (grain, livestock).

  • Urbanization: Growth of cities and wage labor.

  • Rise of middle class and new gender roles → “Cult of Domesticity.”

  • Immigration: Irish and German immigrants filled factory jobs.


4.4 — The American System and Regional Tensions

🧩 Henry Clay’s “American System”

Goal: Unite the regions economically.

  1. Protective Tariffs → help U.S. industries compete.

  2. National Bank → stabilize currency.

  3. Internal Improvements → roads, canals, infrastructure.

💣 Controversy

  • South opposed it: tariffs hurt them (they relied on imports).

  • North and West supported it: helped factories and trade.

  • Second Bank of the U.S. (1816) caused debate about federal power.

  • Panic of 1819: first major economic depression — caused by bank over-loaning → many blamed the Bank.

🌎 Sectionalism Emerges

  • Missouri Compromise (1820):

    • Missouri = slave state

    • Maine = free state

    • Slavery banned north of 36°30′ line in Louisiana Territory

  • Temporarily balanced slavery debate but exposed growing divisions.
