The Indian Removal or Indian Removal was a policy of the United States government in the nineteenth century that sought to move the Amerindian tribes (or "Native Americans") that lived in the east of the Mississippi River to land west of the river. During the decades that followed the War of the Independence of the United States, the rapid increase of the population of the country resulted in numerous treaties in which Native American lands were purchased. Finally, the government of the United States began to encourage the Indian tribes to sell their lands by offering them land in the west, outside the borders of the then existing states of the country, where the tribes could settle again. This process was accelerated by the passage of the Forced Transfer of the Indians Act of 1830, which provided funds to President Andrew Jackson to carry out land exchange treaties ("relocation"). It is estimated that some 100,000 Amerindians were moved west as a result of this policy, most of them emigrating during the 1830s, settling in what was known as the Indian Territory.

The Relocation Act did not actually order the transfer of any American Indian. Rather, it authorized the President to negotiate land exchange treaties with tribes living within the borders of the United States. In the Louisiana Purchase of 1803, the United States had acquired the right over an enormous amount of land west of the Mississippi River. Before the approval of this law, the treaties had been carried out to encourage the Indian tribes to move their settlements to this place - which eventually became known as the "Indian Territory" - by exchanging it with their tribal lands in the East. The approval of the Removal Act greatly accelerated this process of land exchange.

As a result, the five tribes were moved to the new Indian Territory in present-day Oklahoma and parts of Kansas. Some Indians evaded the transfer, while others who lived on individual plots of land (instead of tribal fields) were exempt from the transfer. Those who stayed behind eventually regrouped into tribal organizations, such as the Eastern Cherokee Union, founded in North Carolina.

a countries leader should be motivated by the common good of the country.
