Explain how the relationship between slavery, industrialism and territorial expansion caused the civil war

Slavery caused the Civil War because the North and South divide deepened because of each region's philosophy. Northern states viewed slavery as immoral and saw no use for slavery in their economic system while Southern states viewed slavery as essential to their cotton economy. Industrialism in the North made slaves irrelevant because free labor, even though preferred, was no longer needed. The moral aspect of slavery trumped the profits that would have been lost by using slavery. Furthermore, most workers in the industries received next to no pay anyway. Territorial expansion contributed to the Civil War because legislators and other citizens continued the argument that the balance between free and slave states should not be upset because it would lead to a pro-slavery or pro-free state Congress.
