While there is strong evidence that the real first Thanksgiving occurred much earlier in other countries, as any grade-schooler can tell you, the one that matters was between the Pilgrims and Native Americans at Plymouth in 1621. The First Thanksgiving was a gathering between the English colonists and the Wampanoag Indians the same natives who helped the Pilgrims cultivate the land and learn to fish, which saved them from starvation. While the Pilgrims meant to celebrate the holiday as a fast (not a feast) to give thanks, the Indians who joined in the three-day affair contributed their harvest celebration traditions, including dance, games and food. They likely ate fish, eels, shellfish, stews, vegetables, and yes, turkey. The meal formed the basis for a peace treaty that lasted between the two groups until King Philip's War in 1675, during which hundreds of colonists and thousands of natives lost their lives.
