Metacom met his end at the hands of a Colonial scouting party in August of 1676. His killers quartered and decapitated his body and sent Metacom's head to Plymouth, where for two decades it would be prominently displayed on a pike outside the colony's entrance. That same year, as the violence drew to a close, the colony of Connecticut declared a "day of Publique Thankesgiving" to celebrate "the subdueing of our enemies."
Perhaps it is not surprising that we choose to remember the Thanksgiving of 1621 and to forget the Thanksgiving of 1676. Who, after all, would not prefer to celebrate a moment of peaceful unity rather than one of bloody conflict? But if our public holidays are meant to be moments for self-reflection as well as self-congratulation, we should think of Thanksgiving not as a perpetual reenactment of the "first Thanksgiving" of 1621 but instead as a dynamic event whose meaning has shifted over time.
