How did Eli Whitney and cotton gin Chang the legacy of the south?

Eli Whitney's invention of the cotton gin in 1793 significantly transformed the Southern economy by drastically increasing the efficiency of cotton processing, which made cotton a highly profitable cash crop. This led to the expansion of cotton plantations and a greater reliance on slave labor, solidifying the South's economic and social systems around slavery. As a result, the cotton gin not only boosted the South's agricultural output but also intensified regional divisions that would eventually contribute to the Civil War. Whitney's invention thus left a lasting impact on both the economy and the societal structure of the South.
