Flip through the pages of almost any American history textbook. Within the first few sections, you will find paragraphs dedicated to the American Revolution and the ideological groundwork that supported it; the pull-yourself-up-by-your-bootstraps mythology that surrounds Abraham Lincoln; the rise of a cotton-based economy in the South and the enslaved manpower that sustained it; the westward expansion of the American population and the lines of communication and transportation that they created in the wake of their migration.
