How did the economy of the U.S. change in the 1800s?

In the 1800s, the U.S. economy underwent a significant transformation from agrarian-based to industrialized. The introduction of new technologies, such as the steam engine and the telegraph, facilitated the growth of industries and transportation, particularly railroads. Additionally, westward expansion and the rise of factories led to increased urbanization and a shift towards wage labor. This period also saw the emergence of a market economy, with greater emphasis on trade and commerce.
