The Missouri Compromise
Type text here
The Missouri Compromise was a federal statute in the United States that regulated slavery in the country's western territories. The compromise, devised by Henry Clay, was agreed to by the pro-slavery and anti-slavery factions in the United States Congress and passed as a law in 1820.
How did this lead up to the Civil War?
The compromise measures appeared to settle the slavery-extension issue, however, and the sectional conflict did not grow to the point of civil war until after the Missouri Compromise was repealed by the Kansas-Nebraska Act (1854) and was declared unconstitutional in the Dred Scott decision of 1857.
