Between 1789 and 1865, about one million enslaved African Americans were transported by force from the older to the newer states of the US. The majority were taken by professional slave traders. This forced migration helped create the antebellum United States and the civil war that destroyed it. It made possible the emergence of cotton empire that fed the spindles and looms of the Industrial Revolution. It was as influential in the shaping of map of U.S. history the United States and yet it isn’t marked on the map.
