Sectionalism
Missouri Compromise
Mexican-American War
Compromise of 1850

Election of 1860

Answer 1

1 — Election of 1860
- Lincoln’s victory directly triggered Southern secession; it was the immediate catalyst for war.

2 — Sectionalism
- Long-term economic, cultural, and political differences between North and South created the underlying conflict.

3 — Mexican‑American War
- Added vast new territories and intensified the fight over whether slavery would expand, leading to crises and compromises.

4 — Dred Scott Decision
- The Supreme Court ruling outraged the North, undermined hope for a legal compromise on slavery, and polarized the country further.

5 — Compromise of 1850
- Temporarily postponed disunion but the Fugitive Slave Act and other provisions increased Northern resistance and Southern distrust.

6 — Missouri Compromise
- Early, important attempt to maintain sectional balance; it delayed war but also highlighted the sectional divide.

7 — Louisiana Purchase
- Opened enormous territory that later raised slavery questions, but its impact on immediate tensions was more indirect and long-term.

8 — Monroe Doctrine
- Primarily a foreign‑policy statement about European interference in the Americas; it had little direct role in causing the Civil War.
