Eli Whitney and the Inventions That Changed America
Eli Whitney transformed American manufacturing with two major innovations: the cotton gin and a system for mass-producing muskets with interchangeable parts. His cotton gin dramatically increased the speed of cotton processing, making cotton production more profitable in the South.
The growth of cotton production also strengthened slavery, as plantation owners expanded enslaved labor to meet rising demand. Meanwhile, Whitney’s manufacturing methods helped advance industrial production in the North. His inventions shaped the nation’s economy and contributed to the growing divisions over slavery.
