The North and South Come to an Agreement
Congress passes the Missouri Compromise that states that slavery is banned north of the 36°0' parallel for all new states admitted from the Louisiana Territory. This allowed Missouri to enter the Union as a slave state, and Maine as a free state. This was especially important to the South, because it kept the balance of slave and free states in the legislative body. Congress would be equally represented by both sides of the issue. This legislature resolved the Tallmadge Agreement failed to sustain.
This was a cause for the Civil War because it legalized the sectionalism of the country. The divide between free and slave states was now legally bound. Eventually, those found with slaves above the parallel believed that it was an infraction on their property rights.
