The America West Indies Triangular Trade
The original triangular trade did not involve Africa. In the  first leg of this trade New England Slavers would go to the West Indies and buy sugar. They would take the sugar back to New England and make it into Rum.  After making the Rum, New England slavers would sail to Virginia and buy Native American Slaves, and take the slaves and Rum to the West Indies and start the trade over again.
Between 1620 and 1776 Black Native Americans were sold as slaves in the Caribbean. Beginning in the 1620’s whites hired warlike Indians to attack the farming Indians who were predominately BNA to supply them with slaves. Up to 1776 600,000 Native Americans were sold into slavery in the Caribbean. 300,000 were killed in slave raids or starved after the raids .
