18. Topic: Industrialism and Sectionalism. Thesis: The exciting textbook American Nation, states that, "American independence and control of a wide and rich domain were the most obvious results of the Revolution." The revolution provided access to vast western lands and for many years western expansion would serve as an element that bound the various sections together. However as the nation expanded different economies developed and regional variations in farming, typically between the West and the South, combined with a nascent Northern and Western industrial colossus and began to divide the nation. Industrialism, which bound the West to the Northwest with ribbons of steel, also isolated the South. And as the decades rolled on sectionalist sentiment resulted in the Union being torn apart.
