The rising importance of cotton cultivation in the South had several interrelated effects:





Increasing European demand for cotton, much like tobacco cultivation in Jamestown, led to a distinct focus on its production as a cash crop. As prices rose, Southern planters attempted to augment their harvests--and their profits--by expanding their estates and investing large amounts of capital in slave labor. Vast increases in slave imports discouraged landowner-wage laborer relationships, which stunted the growth of a middle class. Additionally, the focus on agriculture as a primary means of profit among the upper class hindered the development of significant manufacturing centers in the South, a factor that contributed significantly to the supply difficulties faced by the Confederacy throughout the Civil War.
