The Southern Argument for Slavery
Nellie Norton
Southern slaveholders often used biblical passages to justify slavery.
Those who defended slavery rose to the challenge set forth by the Abolitionists. The defenders of slavery included economics, history, religion, legality, social good, and even humanitarianism, to further their arguments.
Defenders of slavery argued that the sudden end to the slave economy would have had a profound and killing economic impact in the South where reliance on slave labor was the foundation of their economy. The cotton economy would collapse. The tobacco crop would dry in the fields. Rice would cease being profitable.
