What was the main outcome of the Frontier Wars?

The results:

-Pushed the Indians west across the Mississippi River.

-The massacre at Wounded Knee in 1890.

-Reduced the Plains Indian population by 50 percent.

-Over 12,000 Indians and whites killed as a result of battle and/or raids.

(Sorry it was hard to find the main outcome I hope this works)
