How were they kept under control?
Most slave holders whipped their slaves. That was the most common punishment. They would beat them until they passed out from the pain or if it was a less severe punishment, then until they started to bleed. Some slave holders did what ever they wanted to their slaves. They beat them, locked them up for days, made them work for longer, starved them, the list went on and on. So to keep them under control, they made the slaves fear them. they made them hurt just thanking about their masters. They were beaten to be kept under control.
