The Indian Removal Act authorized the President to forcibly remove Native Americans from U.S. Territory.

Explanation:

The Indian Removal Act was a law adopted on May 28, 1830, which stipulated that the American Indian tribes resident east of the Mississippi River would be moved to areas west of it. Although the law was formulated so that the movement would take place voluntarily, heavy pressure and military force were generally used to clear out the affected tribes from their lands. The effects as well as the background to the law were part of the gradual displacement of the Indians in the United States during the 19th century.
