The lower Mississippi valley, as a distinct geopolitical region, is representative of the antebellum South. Arkansas and Tennessee represents the upper South and Louisiana and Mississippi the lower South. The region demonstrates much geographical diversity, but the main division is between the alluvial areas, where plantation agriculture and large slaveholdings predominate, and the uplands, which feature farming and small-scale slaveholding. The 1.16 million slaves of the region constitute more than a third of the Confederacy’s slave population. The slaveholders of the antebellum South are a distinct elite, especially in the lower Mississippi valley. The slave populations of the region also engender complex communities and a vibrant cultural life. Other than the South Carolina lowcountry and the Chesapeake, the lower Mississippi valley achieves the highest stage of historical development as a slave society within the antebellum South.
