“The mid-nineteenth century brought unprecedented transformations to all aspects of life in the region (Map 9). Coal, steel, and steam fueled industrial expansion, binding the Chesapeake region more firmly with the rest of the nation and the world. Scientific advances and religious revivals challenged people’s views. New crops were introduced, and old plants were farmed in new ways … In the Chesapeake Bay region, North-South tensions eclipsed earlier differences between the Coastal Plain and Piedmont.”
