Explanation:

The sharecropping system bolted a great part of the South into a dependence on cotton.  

While sharecropping gave African Americans self-rule in their day by day work and public activities, and liberated them from the group work framework that had commanded amid the bondage time, it frequently brought about tenant farmers owing more to the landowner than they were able to repay.

Some blacks figured out how to gain enough money to move from sharecropping to leasing or owning land before the finish of the 1860s, yet a lot more strayed into the red or were constrained by neediness or the danger of viciousness to sign out of line and exploitative sharecropping or labor contracts that left them little hope of improving their situation.
