For historical context and background about what the United States did to native peoples, here’s information about the Indian Removal Act (which President Andrew Jackson signed into law in 1830):
“It gives me pleasure to announce to Congress that the benevolent policy of the Government, steadily pursued for nearly thirty years, in relation to the removal of the Indians beyond the white settlements is approaching to a happy consummation.

This law lead to the Cherokee Nation’s “Trail of Tears.”

Native American studies scholar Gerald Vizenor’s term “survivance” from his book Manifest Manners: Narratives on Postindian Survivance: “Survivance is an active sense of presence, the continuance of native stories, not a mere reaction, or a survivable name.
