Chapter 13: Forging the National Economy – Market Revolution

The period between 1790 and 1860 witnessed the dramatic expansion known as the market revolution, fundamentally altering the United States from an agricultural subsistence economy into a dynamic national commercial network. This economic transformation was driven by two major demographic shifts: relentless westward movement and explosive population growth fueled by massive international migration, primarily from Ireland and Germany, often settling in ethnic communities in fast-growing northern cities. These immigrants, fleeing crises like the potato famine and political upheaval, faced intense resentment from older inhabitants, leading to a rise in nativist sentiments and the formation of groups such as the Know-Nothing party, frequently fueled by strong anti-Catholic prejudice. Simultaneously, the Industrial Revolution took hold, accelerated by pivotal mechanical inventions. Samuel Slater established the factory system in America, while Eli Whitney's cotton gin solidified the South's reliance on King Cotton and expanding slavery, even as his concept of interchangeable parts mechanized northern manufacturing. Essential for linking the specialized regional economies—the South supplying raw materials, the West providing food, and the East producing textiles and machinery—was the transportation revolution. Key developments included turnpikes, the use of steamboats to make rivers two-way arteries, the Erie Canal, and the eventual dominance of railroads, which strategically bound the North and Midwest together economically. These profound economic shifts changed American society; workers organized for better conditions (partially legitimized by the Commonwealth v. Hunt ruling in 1842), and women’s roles evolved. The home became a separate domain governed by the cult of domesticity, which, paradoxically, also fostered female independence through domestic feminism as families grew smaller and more child-centered. While manufacturing drove a significant increase in prosperity and led to the emergence of a large middle class and a wealthy elite, it also resulted in a large and growing population of the laboring poor.
