The line of latitude that separates the Slave States from the Free States of the USA is known as the Mason-Dixon Line. This boundary was established in the 1760s by Charles Mason and Jeremiah Dixon to settle a border dispute between the colonies of Maryland, Pennsylvania, and Delaware. The Mason-Dixon Line became synonymous with the division between the Northern states that were free states and the Southern states that were slave states. This boundary played a significant role in the lead up to the Civil War, as tensions between the two regions escalated over the issue of slavery. The Mason-Dixon Line roughly follows the 39th parallel north, running from Pennsylvania in the north to Maryland and West Virginia in the south. It served as a symbolic and physical barrier between the two opposing sides of the slavery debate in the United States. The division between the Slave States and Free States was not just about the legality of slavery but also about differing social, economic, and political ideologies. The Free States were generally more industrialized and urban, while the Slave States relied heavily on agriculture, particularly the production of cotton using slave labor. The legacy of the Mason-Dixon Line and the divide it represented can still be seen in the cultural and social differences between the North and the South in the United States today. While slavery has long been abolished, the effects of this historical divide continue to shape the country's politics and society.

Its legacy continues to influence the country's history and culture, highlighting the deep-rooted impact of the slavery debate on American society.
