Why did missouri’s request to join the union increase sectionalism?

Well, Missouri's request for statehood had touched off a sectional crisis between the northern, non-slave states and also the south, slaveholding states. The crisis was whether Missouri and future states, in general, would become slaveholding states or not. With the large expanse of land from the Louisiana Purchase. This crisis was solved by having every state north of parallel 36°30' that was newly christened into the union would be a free state any state below that line would be a slave-holding state.
