Explain how the North, South, and West were linked through industrial and economic expansion

The North, South, and West were physically linked through the improved transportation developments of the early 19th century. The regions were also linked through the expansion of industrial pursuits. Most factories were located in the North due to the swift flowing rivers that generated power and the large immigrant populations who supplied cheap, unskilled labor in the factories. The American South and West supplied the raw materials needed to manufacture finished products. Goods were transported by road, canal, or rail as a result of the widespread internal improvements to the infrastructure made by the state and the federal governments. Henry Clay was an immensely important figure in the progress of American industrialization and economic nationalism.
