Hello, my name is Matt and I'll be your BrainGem helper today! The Mississippi River had lots of plantations near it. On Plantations there were dozens of slaves working. This was also were there was a large black community. I went to a planation 2 years ago. It was called the Oak Valley Plantation. (Just if you want to give it a Google). I hope that we at BrainGem can help you in the future!
