The answer is slave. The Antebellum Era, likewise roughly denoted to as the Plantation era, was an era in the past of the Southern United States, from the late 18th period up until the beginning of the American Civil War in 1861, manifested by the economic development of the South grounded on slave-driven plantation agribusiness.
