The document discusses the historical challenges faced by Native Americans, including: 1) The Homestead Act of 1862 which allowed settlers to claim western lands if they worked the land for five years, building conflicts with Native Americans. 2) The six phases of historical unresolved grief that Native Americans experienced due to colonization, including genocide, disease, and the traumatic events like the Wounded Knee Massacre. 3) The Dawes Act of 1887 which divided reservation lands into privately owned sections, destroying tribal unity and communities by ending communal hunting and eventually selling "surplus" lands.
