4. Summarize the reasons Native American culture was irrevocably changed by the end of the 1800s?

By the end of the 1800s, Native American culture was irrevocably changed due to a combination of forced displacement, violent conflicts, and assimilation policies imposed by the U.S. government. The westward expansion of settlers led to the loss of ancestral lands and resources, while events like the Indian Wars decimated populations and traditional ways of life. Additionally, initiatives such as the Dawes Act aimed to assimilate Native Americans into Euro-American society, undermining communal practices and cultural identities. These factors collectively disrupted traditional lifestyles and resulted in significant cultural transformation.
