Explanation:

The Missouri Compromise of 1820, while repealed just 30 years later, is a benchmark moment in United States history. A bill created with the idea of finding peace and a solution to an ever-growing debate, the Missouri Compromise of 1820 would perpetuate the tensions and debates revolving around the hot-button issue of slavery for years to come.  

The exchange of Missouri as a slave state in favor of the ban of slavery north of the 36-30 line and a free Maine was just a temporary solution to the problem. Southerners believed federal regulation of slavery was unconstitutional and to impose a restriction on the instituion of slavery was out of their jurisdiction. Northerners saw the deal as a way to keep the score even and keep the current state of the nation at bay. It was clear that both regions saw the compromise as unjust or unfair to their own side.

Just 30 years later, the debates repeated itself in the form of Kansas and Nebraska. The Missouri Compromise was struck down as unconstitutional, and slavery and anti-slavery proponents rushed into the territory to vote in favor or against the practice. The rush, effectively led to massacre known as Bleeding Kansas and propelled itself into the very real beginnings of the American Civil War.
