Answer:
Labors (slave)
Step-by-step explanation:
The Southern states in the first half of the 19th century depended on the labors to perform work in the fields of cotton plantations. The labors were the African American who were brought from Africa and put into auctions to sell. For the plantation owners, slavery was the backbone of the economy of the South. Slaves were forced to work in the fields of cotton from sun up to fall. They helped the South in getting rich and prosper.
