What year did slavery start in the US?

The Start of Slavery in North AmericaHistorians normally date the start of slavery in the North American colonies to 1619. That year, a Dutch ship carrying African slaves docked at Point Comfort, which served as Jamestown's checkpoint for ships wanting to trade with the colonists.

The crew of the Dutch ship was starving, and as John Rolfe noted in a letter to the Virginia Company's treasurer Edwin Sandys, the Dutch traded 20 African slaves for food and supplies.

If the Question is slavery in the U.S. that would be 1776 to 1865.
