The Missouri Compromise took place in 1820. The Missouri compromise created a large amount of conflict between the North and South. Each side wanted to have more land so it would be able to overpower the other.The states decided to make Missouri and Maine a free states. If this was carried out there would be an uneven amount of free to slave states. The North and South eventually came to a compromise.The results were Maine would be admitted as free state while, Missouri would be admitted as a slave state. That wasn't the only change this compromise brought. Slavery would not be allowed anywhere Northwest on the United States.
