Answer :
Sectionalism is the seperation bewteen two groups. Most all industry (factories) were in the North, and materials (such as cotton, sugar) were in the south. The south provided the north with raw materials and in return for goods/products. This caused sectionalism, because the North were generating more profits than the south. The south only had crops, and as the price of crops continued to go down, southerners were getting angry. The industrial revolution further divided the country, it was the urban vs. the rural.
