The antebellum South was a diverse but profoundly unequal society whose economy, politics and social order depended heavily on racial slavery. Cotton brought enormous wealth, yet that wealth rested on coerced labour. The struggle to protect and expand slavery eventually drove secession and the American Civil War.
The expression antebellum South refers to the Southern United States before the Civil War, especially during the decades between the War of 1812 and the outbreak of war in 1861.
This period is often associated with plantations, cotton fields and wealthy slaveholders. However, the South was neither socially uniform nor economically simple. It contained large plantations, small farms, growing towns, ports, factories, mountain communities and frontier settlements.
One institution nevertheless shaped the entire region: slavery. Enslaved labour produced much of the South’s wealth, influenced its political power and defined its racial hierarchy. Even white Southerners who owned no enslaved people lived within a society organised to protect slave property and white supremacy.
