What this topic is asking
Topic 4.3 asks you to explain how growing regional (sectional) interests shaped national politics after 1800. The exam threads together the War of 1812, the misnamed Era of Good Feelings, Henry Clay's American System, and the Missouri Compromise, showing how a surface of national unity sat atop deepening divisions, above all over the expansion of slavery.
The War of 1812 and rising nationalism
The War of 1812 against Britain grew from maritime grievances and frontier tensions. Militarily it was largely a draw, but its effects mattered:
- It produced a wave of nationalism and pride (and the heroics that launched Andrew Jackson's career at New Orleans).
- It discredited and destroyed the Federalist Party, which had opposed the war, leaving the Democratic-Republicans dominant.
The Era of Good Feelings and the American System
The Missouri Compromise
The deepest fault line, slavery's expansion, broke the surface in 1819 to 1820.
Worked example: weighing section against union
Try this
Q1. Name the 1820 agreement that admitted Missouri as a slave state and Maine as free. [Recall]
- Cue. The Missouri Compromise, which also barred slavery north of 36 degrees 30 minutes.
Q2. Explain why the so-called Era of Good Feelings did not end sectional division. [Short explanation]
- Cue. Although the collapse of the Federalists produced one-party rule and a surface of unity, the regions still held sharply different economic interests and clashing views on slavery, as the Missouri crisis of 1819 to 1820 soon revealed.

Contextualization (1): the market revolution and westward expansion that gave each region distinct economic interests.
Evidence (2): the American System debate; the so-called Era of Good Feelings; the Missouri Compromise.
Analysis (2): explain HOW economic and slavery interests pulled the regions apart, then add complexity by noting forces of unity such as nationalism after the War of 1812.
