In which case policy or situation did the motto and ldquokill the Indian but save the man and rdquo play an important role in western expansion?

The motto "kill the Indian, but save the man" was a guiding principle behind the U.S. government's Indian boarding school policies in the late 19th and early 20th centuries. This philosophy aimed to assimilate Indigenous peoples into Euro-American culture by eradicating their native identities, languages, and traditions. Such policies facilitated western expansion by undermining Indigenous sovereignty and facilitating the appropriation of their lands for settlers and economic development. The motto reflects the broader context of colonial attitudes that justified the displacement and cultural genocide of Native American populations.
