 Three years later, after the Indian massacre of 1622, the Berkeley Hundred site and other outlying locations were abandoned and colonists moved their celebration to Jamestown and other more secure spots.The most prominent historic thanksgiving event in American popular culture is the 1621 celebration at the Plymouth Plantation, where the settlers held a harvest feast after a successful growing season.Autumn or early winter feasts continued sporadically in later years, first as an impromptu religious observance and later as a civil tradition.
