What did The cotton gin new farmlands in the west and the demand for cotton in northern and European textile factories lead to?

The cotton gin, invented by Eli Whitney in 1793, significantly increased the efficiency of cotton processing, making it easier to separate seeds from cotton fibers. This innovation spurred the expansion of cotton cultivation in the new farmlands of the West, leading to a dramatic increase in cotton production to meet the growing demand from northern and European textile factories. As a result, the cotton industry became a cornerstone of the American economy, reinforcing the reliance on slave labor in the South and intensifying regional tensions that contributed to the Civil War.
