Final answer:
Sharecropping was the type of farm tenancy that developed after the Civil War, where landless workers, often former slaves, farmed land in exchange for farm supplies and a share of the crop.
Step-by-step explanation:
After the Civil War, a type of farm tenancy called sharecropping developed. Sharecropping involved landless workers, often former slaves, farming land in exchange for farm supplies and a share of the crop. This system emerged because many former slaves did not have the opportunity to purchase land of their own, so they had to rent land from white farm owners and pay them with a portion of their harvested crops.
