Part 3: Summary

Most slave imports in the US happened during the colonial period with few slaves coming after independence. The US was also less active in the trade the Great Britain, France, Portugal/Brazil, and the Netherlands. Most slaves came to the states of Virginia and South Carolina. It can be concluded that the US had less of a role in the slave trade than several European countries. This is especially true for northern states, since the south recieved the bulk of slaves.
