The Antebellum South (also known as the antebellum era or plantation era) was a period in the history of the Southern United States from the conclusion of the American Revolutionary War in 1783 until the start of the American Civil War in 1861. The Antebellum South was characterized by the use of slavery and the culture slavery fostered. As the era proceeded, Southern intellectuals and leaders gradually shifted from defending slavery as an embarrassing and temporary system, to a full-on defense of slavery as a positive good, and harshly criticized the budding abolitionist movement.
