Most of us associate the holiday with happy Pilgrims and Indians sitting down to a big feast. And that did happen - once.
The story began in 1614 when a band of English explorers sailed home to England with a ship full of Patuxet Indians bound for slavery. They left behind smallpox which virtually wiped out those who had escaped. By the time the Pilgrims arrived in Massachusetts Bay they found only one living Patuxet Indian, a man named Squanto who had survived slavery in England and knew their language. He taught them to grow corn and to fish, and negotiated a peace treaty between the Pilgrims and the Wampanoag Nation. At the end of their first year, the Pilgrims held a great feast honoring Squanto and the Wampanoags.
But as word spread in England about the paradise to be found in the new world, religious zealots called Puritans began arriving by the boat load. Finding no fences around the land, they considered it to be in the public domain. Joined by other British settlers, they seized land, capturing strong young Natives for slaves and killing the rest. But the Pequot Nation had not agreed to the peace treaty Squanto had negotiated and they fought back. The Pequot War was one of the bloodiest Indian wars ever fought.
