This proposal reflected the growing tensions between pro-slavery and anti-slavery factions in the United States, as it sought to limit the expansion of slavery into new western territories.

Popular sovereignty was a political doctrine that allowed the residents of a territory to vote on whether to permit slavery. This concept emerged in the mid-19th century as a way to address the contentious issue of slavery's expansion into new states and territories. Instead of Congress making a blanket decision, the idea was to empower local populations to determine their own laws regarding slavery, reflecting democratic principles and aiming to ease tensions between pro-slavery and anti-slavery factions. This approach, however, ultimately led to increased conflict and division in the United States.
