APUSH Unit 4: Jefferson to Jackson

APUSH Unit 4 covers the dramatic transformation of the early American republic (circa 1800–1848) — a time of political change, economic growth, and powerful reform movements. This guide gives you a clear roadmap to the people, events, and themes you need for class and the AP exam. Expect to learn about the Jeffersonian vision, the War of 1812 and Era of Good Feelings, the Market Revolution, Jacksonian democracy, westward expansion, and the major social reform movements that reshaped American life.

• Quick wins: focus on cause-and-effect chains (e.g., Market Revolution → urban growth → reform movements).
• Exam tip: practice DBQ/LEQ prompts that ask about continuity/change and national vs. sectional priorities.
• Why it matters: these developments shaped modern American politics, economic systems, and social activism — and you’ll spot their echoes in today’s debates.
