How many slaves were imported into the US?

Answer 1

Counting South America, over 3,000,000 slaves were sent here from Africa. Including only North America, the number drops to about 250,000, although conditions of early colonial slavery was very different from slavery that spread through the 18th and 19th centuries. Racial inferiority was not implied through the mid to late 1600's, with African slaves being on par with European slaves as indentured servants. It was not until the 1700's that slaves became grouped with Natives as subhuman, and it was not until the mid-1800's that brutality reached its most horrifying peak.

Answer 2

360-400,000.
