Deep South

The Deep South is a descriptive category of the cultural and geographic subregions in the American South. Historically, it is differentiated from the "Upper South" as being the states which were most dependent on plantation type agriculture during the pre-Civil War period. The Deep South was also commonly referred to as the Lower South or the Cotton States. People of English ancestry traditionally predominate in every part of the Deep South except for southern Louisiana.

Today, the Deep South is usually delineated as being those states and areas where things most often thought of as "Southern" exist in their most concentrated form.
