In 1798, Eli Whitney patented the cotton gin, revolutionizing the cotton industry by streamlining the separation of cotton fibers from seeds. This innovation dramatically increased efficiency in cotton processing, greatly enhancing productivity. Primarily impacting the United States, the cotton gin led to heightened cotton production, facilitating its emergence as a vital agricultural commodity. Consequently, it became a cornerstone raw material for the burgeoning textile industry in the 19th century.
