How did the spirit of manifest destiny and federal polices guide the outcome of native american tribes on the great plains and west of the great plains?

Manifest Destiny was a philosophy that considered the United States was divinely ordained, justifiable and inevitable to expand its borders.

This philosophy encouraged the convergence of social, economic, and political factors helped urge the speed of westward expansion in the 19th century. With the Louisiana Purchase in 1803 people were driven to the west, white settlers and proponents of expansion began to voice concerns over what they considered an obstacle to settlement - The American Indian tribes that lived there -. White settlers considered the lands east of the Mississippi River a great place to raise cattle, wheat, and cotton.

The convergence of Manifest Destiny and the need to expand was used to rationalize the removal of American Indians from their native homelands. The Indian Removal Act of 1830 was signed into law and authorized the president to reserve land west of the Mississippi River and exchange it for Native American land to the east of the Mississippi.
