A flag honoring the Wampanoag Indians flew over the United States Capitol Building in Washington, D.C. The Civil Rights efforts of the 1960s translated into a heightened political and social presence for Native Americans in the 1970s. Organizations such as the American Indian Movement (AIM) staged political protests to draw attention to unjust treatment of Native Americans.
On Thanksgiving Day 1970, 25 Native Americans dressed in traditional garb held a day of mourning at Plymouth, Massachusetts. They gathered before the statue of Massassoit, the Wampanoag Chief who aided the Plymouth Colony, and proceeded to bury Plymouth Rock under mounds of sand.
A year after the Wampanoag flag flew over the Capitol, a descendant of one of the Plymouth settlers presented it to the current Wampanoag Chief in a Thanksgiving Day ceremony.
