Final answer:
During the late 1850s, settlers wanted to either exterminate or assimilate the Native American tribes. They negotiated treaties, but many were violated, leading to conflicts and forced removals.
Step-by-step explanation:
During the late 1850s, the settlers wanted to either exterminate the Native American tribes or assimilate them into American society through an Americanization policy. This policy aimed to impose individual land ownership, Christian worship, and education for children on the Native Americans, in an effort to change their way of life. Settlers negotiated treaties to move tribes out of the path of White settlers and established reservations. However, many of these treaties were violated, leading to conflicts and forced removal of the tribes from their homelands.
