The Missouri Compromise of 1820 established the latitude 36°30′ as the northern limit for slavery to be legal in the territories of the west. As part of this compromise, Maine (formerly a part of Massachusetts) was admitted as a free state.
Explanation:
This parallel of latitude is particularly significant in the history of the United States as the line of the Missouri Compromise, which was used to divide the prospective slave and free states west of the Mississippi River, with the exception of Missouri, which is mostly north of this parallel.
Answer: When Missouri became a state, it threw off the equality, so a line was made, 36'30, which was used to say that the states above the 36'30 would be called free states and states below the line would be slave states, where slave trading was allowed. These were the various views on slavery.
