Industrial Revolution and the Atlantic Slave Trade

All that I remember about that Industrial Revolution or know is that there were many factories, railroads, and vehicles such as trains then being manufactured. Also that it required more forced labor and it made tons of people have to work on/with it. The Industrial Revolution was also away to increase the technology, as I said at the beginning certain vehicles and labor facilities ie: factories would have been made because of labor and inside a factory there had to have been labor or else the factory would not have flourished or even stayed in business. The Atlantic Slave Trade I remember being where European and even Americans would come by boat to the shores of Africa and round up local citizens who then would be forced to do slave work or more labor, but not before the families were auctioned off by buyers looking for some cheap work that would not cost them much. By separating the slaves they would literally tear apart families without a care in mind. There was also a connection between the two if I recall that once the slaves were sent to America, the Americans would send minerals and resources such as wood to England who then used these resources to build factories and induce labor onto some of the slaves they rounded up to work in the factories.
