Hook & Mini-Lesson
Day 1: The Road to War
Hook (10 min): Display a map showing the Missouri Compromise line (36°30'). Ask: Why would Americans draw a line across the country to decide where slavery was legal? What does that tell you about how important this issue was?
Mini-Lesson (20 min): Four Causes of the Civil War
1. Slavery: The central cause. The southern economy depended on enslaved labor producing cotton for export. By 1860, 4 million people were enslaved. The North had moved away from slavery (though its mills used Southern cotton).
2. Economic Differences: The North was industrializing — factories, railroads, cities. The South remained agricultural — plantations, cash crops, dependence on slavery. These different economies created different interests on tariffs, internal improvements, and western expansion.
3. Political Failures:
The Missouri Compromise (1820): Admitted Missouri as a slave state, Maine as free, drew a line at 36°30'.
The Compromise of 1850: California free, Fugitive Slave Act strengthened, popular sovereignty in the West.
The Kansas-Nebraska Act (1854): Repealed the Missouri Compromise, led to "Bleeding Kansas."
Dred Scott v. Sandford (1857): The Supreme Court ruled that Black Americans were not citizens and Congress couldn't ban slavery in territories.
4. The Election of 1860: Abraham Lincoln won without a single electoral vote from the South. Within weeks, South Carolina seceded. Ten more southern states followed, forming the Confederate States of America.
Student Activity (15 min): "Causes Ranking" — In groups, students rank the four causes by importance and defend their ranking. Class Can you separate slavery from the other causes, or were they all connected?
Exit Ticket & Discussion
Exit Ticket (10 min): The Civil War took 620,000 American lives — more than all other American wars combined before Vietnam. Was there any way to avoid it? What could have been done differently?
Discussion Questions:
Southern states argued they had a right to secede. Did they? Can states leave the Union?
Lincoln's goal was initially to preserve the Union, not end slavery. Does that make him less of a hero?
The war ended slavery but not racism. What does that tell us about what laws can and cannot change?
