"And as for the other matter - the first Thanksgiving. It's a very poetic idea, the whites and the Natives putting aside their differences and sitting down to a dinner together. Unfortunately, it never happened. Thanksgiving began in 1637, when colonists set fire to a Pequot village, destroying the tribe's homes and crops. When the Pequot people saw the fire and ran, the colonists gave chase, ultimately slaughtering seven hundred Pequot men, women, and children. At the sight of the carnage, Governor John Winthrop declared, 'This day forth shall be a day of celebration and Thanksgiving.'"
Sounds to me like John Winthrop was the 17th century's Trump.
