What was the most important crop in the south for the 19th sentry?

The most important crop in the South during the 19th century was cotton. Often referred to as "King Cotton," it became the backbone of the Southern economy, driving both agricultural practices and trade. The invention of the cotton gin in 1793 significantly boosted cotton production, leading to increased demand for land and labor, which in turn intensified the reliance on slavery. Cotton's dominance shaped social, economic, and political dynamics in the region, contributing to tensions that eventually led to the Civil War.
