The Deep South or the Lower South is a cultural and geographic subregion of the Southern United States. The term is used to describe the states which were most economically dependent on plantations and slavery, generally Louisiana, Mississippi, Alabama, Georgia, and South Carolina. East Texas, North Florida, the Arkansas Delta, South Arkansas, West Tennessee, and the southern part of North Carolina are sometimes included as well. Following the end of the American Civil War in 1865, the region experienced significant economic hardship and became a focal point of racial tension during and after the Reconstruction era.
Before 1945, the Deep South was often referred to as the "Cotton States" since cotton was the primary cash crop for economic production. The civil rights movement in the 1950s and 1960s helped usher in a new era, sometimes referred to as the New South. The Deep South is part of the highly religious, socially conservative Bible Belt and currently is politically a stronghold of the Republican Party, after historically being one for the Democratic Party.
