Answer :
Answer:
Board of Indian Commissioners
Explanation:
At that time, President Ulysses believed that the hostility between american Indians and the American people is caused by difference in principle and religion.
This is why he established Board of Indian Commissioners.
Board of Indian Commissioners were working together with the christian church to assimilate the american Indians who lived in preservation. Grant hoped that by teaching the way of Christianity will make both the Indians and american citizens reach a mutual understanding over one another. Later on we found out that his method wasn't really effective.
