There was a time in the American antebellum South like Georgia, Mississippi, Missouri, Alabama, and South Carolina where economic, social, political, cultural, and religious relations of the American society were established on the bloody foundations of slavery of blacks. These black slaves were brought bounded in chains from the West Coast of Africa and today's West Indies. Such black slaves were bought and sold to work on the cotton, tobacco, and sugar cane plantations of white slave owners.
Now, most of us Indians who have some basic idea of the 'system of slavery' know physical exploitation, involuntary bonded labour without any wage is the common sight in slavery. However, in the case of the American plantations in the south, black slaves used to be whipped, beaten up, starved, hanged, burned alive, lynched, sexually exploited by white slave masters.
