How was industrial development from 1800 to 1860 a factor in the relationship between the northern and southern states?
Industrial development helped to make the relationship between North and South more difficult because industrialization did not proceed at the same pace in both sections. During this time period, the North industrialized and the South did not. This led to sectional conflict such as that seen in the Nullification Crisis. Industrialization also helped to tie the North to the western states. This made the South feel more isolated and more in danger as the antebellum period wore on. Overall, the fact that the North industrialized much more than the South drove the two sections farther apart during this time period.
