What caused the dissagreement between the north and south?

The disagreement between the North and South in the United States primarily stemmed from differing economic systems, social structures, and views on slavery. The North, with its industrial economy, favored a more centralized government and policies that promoted free labor, while the agrarian South relied heavily on slave labor for its cotton-based economy and sought to maintain states' rights. This fundamental clash over economic interests and human rights ultimately escalated tensions, leading to the Civil War. Other factors, such as territorial expansion and political power struggles, further exacerbated the divide.
