Nashville, Tennessee, slave market
While the biggest slave market in the state was along the Mississippi River in Memphis, land routes connecting Nashville to the ports at New Orleans, Louisiana, and Natchez, Mississippi, sufficed to deliver human cargo to and from Nashville. By 1850, slaves were a major export of the U.S. state of Tennessee, and Nashville served that market with no fewer than eight slave-trade brokers.
