Explanation:
The treatment of slaves in the United States varied widely depending on conditions, time, and place. Generally speaking, urban slaves in the northernmost Southern states had better working conditions and more freedom than their counterparts on Deep South plantations. As slavery became more entrenched and slaves both more numerous and valuable, punishments for infractions increased.
Treatment was generally characterized by brutality, degradation, and inhumanity. Whippings, executions, and rapes were commonplace, and slaves were usually denied educational opportunities, such as learning how to read or write. Medical care was often provided to slaves by the slaveholder’s family or fellow slaves who had gleaned medical knowledge via ancestral folk remedies and/or experiences during their time in captivity. After well-known rebellions, such as that by Nat Turner in 1831, some states even prohibited slaves from holding religious gatherings due to the fear that such meetings would facilitate communication and possibly lead to insurrection or escape.
Isolated exceptions existed to the generally horrific institution of slavery. For instance, there were slaves who employed white workers, slave doctors who treated upper-class white patients, and slaves who rented out their labor. Yet these were far from common occurrences.
