Answer: A way to keep plantations running.
Step-by-step explanation:
Slavery played a fundamental role during the American Civil War. Most of the South's slaves were used in the plantations. During and before the Civil War, slaves fought for their own freedom, and many of them fled from servitude during the war.
Slavery was the main reason for secession, primarily for the Southern opposition to the efforts by Northern antislavery political powers to prevent the development of slavery in western states.
