By J. A. SACCO

2. Preview- The Causes of the Civil War
Starter- What were the causes of the American Civil War?
Manifest Destiny-expansion-determine slavery
Cultural differences between the North and South
Poor leadership in gov’t- don’t want to deal with the problem
Inability/Failure of compromise
Breakup of national parties into sectional parties
Reform movement- steady growth of abolitionist movement

3. Missouri Compromise of 1820
First crisis of many- Missouri applies for statehood in 1819.
Talmadge Amendment
NY Congressman James Talmadge proposes two amendments to the Missouri statehood bill
Bar additional slaves from being brought into Missouri- already have 16% of population
Emancipate Missouri slaves born after admission when slave reaches 25th birthday
* So if Missouri to become a state, it must agree to eventually become a free state

4. Missouri Compromise of 1820
Why did the statehood bill of Missouri become a sectional crisis between the North and South?
1819
North
Control the House of Reps. because of a larger population in North
If more Southern states are added, may loose control of House as they did in the early years of the republic.
South
Control Senate with Illinois often voting as a Southern state
Must keep it at least even in Senate
The Talmadge Amendment passes the House but gets shot
down in the Senate!

5. Henry Clay averted a crisis with the Missouri Compromise of 1820.
Maine and Missouri became states at that time—one free, the other slave.
A line was drawn across the territories; any new state south of Missouri’s southern border would be a slave state, anything north a free state.
Henry Clay averted a crisis with the Missouri Compromise of 1820.
Still, Southerners were worried. They blamed the Missouri debates when Denmark Vesey, a black freedman, planned an unsuccessful slave revolt in 1822.
