Due to the railroads, american settlers were able to travel west in larger numbers. how did this migration impact american indians

I believe the answer is: American Indians' way of life changed because buffalo herds were destroyed for commercial markets.

The migration make a lot of people able to settle to the territory that previously been occupied by Americna Indians. This force some of them to leave the territory or change their way of life to conform and adapt to the new way of life created by the settlers.

the big stick policy was to still look powerful, and be nice at the same time. the big stick policy was also to countries who were at war, find peace with eachother.

the dollar diplomacy was to expand american business and get it to latin america, for that would be good for the economy.

you my friend, your regards.
