Answer:
because they were considered savages who practiced no religion.
Explanation:
There were various reasons why there was such a push in the late 18th century to "civilize" Native Americans. Native Americans were considered to be "less developed" than Western people, and it was seen as a charitable action to help them reach a higher level of development. Moreover, it was believed that, if Native Americans assimilated, less conflict would ensue in the relationships between white people and Native Americans. Finally, the religious ideas of the colonizers encouraged them to try to convert the Native Americans, as this would ensure their "salvation."
