What happened to the native americans in the way of westward expansion
Greeley [361]

Native Americans that were in the way of the United States expanding west were forced to move to present day Oklahoma. This migration that occurred is known as the Trail of Tears, where <em>thousands </em>of Native Americans died.

The United States government wanted to move west, but the Native Americans homeland was in the way, so they had to come up with a solution to move them. The passing of the Indian Removal Act in 1830 was a big step to moving the Native Americans, although most of them did not want to move. When the United States government tried to make deals, most of them did not budge and when the deadline came around, most of the Native Americans were still there. This finally caused President Jackson to send troops to force them out.

This march is known as the Trail of Tears, where the Native Americans were forced from their homeland. This migration was exhausting, even for the soldiers leading it. Along the way, the Natives were forced into camps and <em>thousands </em>died from starvation, weather, and even diseases.
