7.3 Cotton economy and international trade

Cotton transformed the American economy in the early 19th century. The invention of the cotton gin, coupled with expanding territories and slave labor, made the South a cotton powerhouse. This crop dominated U.S. exports, shaping trade relationships and fueling economic growth.

However, the South's reliance on cotton had drawbacks. It led to soil depletion, economic vulnerability to price fluctuations, and a lack of diversification. The cotton economy also reinforced slavery, setting the stage for future conflicts.
