How did Eli Whitney encourage the westward expansion?

Eli Whitney encouraged westward expansion primarily through his invention of the cotton gin in 1793, which revolutionized the cotton industry by making the processing of cotton much more efficient. This innovation led to a surge in cotton production in the southern states, creating a high demand for land and labor, which in turn spurred migration westward. Additionally, Whitney’s introduction of interchangeable parts in manufacturing facilitated the growth of industries that supported westward expansion, such as transportation and agriculture. Overall, his contributions helped shape the economic landscape that drove settlers to new territories.
