In 1621, a group of Pilgrims and Native Americans came together for a meal that many Americans call "The First Thanksgiving." But get this—it wasn't the first, and the meal itself wasn't so special either. The event was actually all but forgotten for hundreds of years…until it was dusted off to bolster the significance of a national holiday. This time on Sidedoor, we talk to Paul Chaat Smith, a curator at the Smithsonian's National Museum of the American Indian, to explore how much of what you think you know about Native Americans may be more fiction than fact.
