The cotton trade refers to the global exchange of cotton as a commodity, which became a cornerstone of the economy in the United States, particularly in the South during the 19th century. This trade was pivotal in establishing and expanding the plantation system, which relied heavily on enslaved labor to produce cotton for both domestic consumption and international markets, especially in Europe and Asia. The profitability of cotton spurred economic growth, social changes, and ultimately played a significant role in shaping regional and national identities.
