What was allowed by the compromise?

The term "compromise" can refer to various historical agreements, but one notable example is the Missouri Compromise of 1820. This compromise allowed Missouri to enter the Union as a slave state while Maine was admitted as a free state, maintaining the balance between free and slave states. Additionally, it established a geographical boundary at the 36°30' parallel, above which slavery was prohibited in the Louisiana Territory. This agreement sought to ease tensions between pro-slavery and anti-slavery factions in the United States.
