Answer:
Two types of assimilation that were forced upon American Indians from the 1860s-1880s were boarding schools and the Dawes Act.
Under the boarding school system, Native American children were taken from their families and sent to boarding schools where they were forced to adopt European-American ways of living, including language, dress, and religion. The goal of the boarding school system was to assimilate Native American children into mainstream American society and to eradicate their cultural identity.
The Dawes Act, also known as the General Allotment Act, was passed in 1887 and aimed to assimilate Native Americans into American society by dividing their communal lands into individual plots that could be owned and sold by individual Native Americans. The act also encouraged Native Americans to adopt European-American farming practices and to become self-sufficient farmers. However, the Dawes Act resulted in the loss of millions of acres of Native American lands and the erosion of Native American cultures and communities.
