What is the purpose of Andrew Jackson's message to congress "On Indian Removal"?

To justify the Indian Removal Act.

Explanation:

The purpose of the speech "On Indian Removal" given by President Andrew Jackson was to justify the Indian Removal Act. This was a law that was passed by the president in 1830, and which allowed the government to take Indian lands within existing state borders and exchange them for unsettled lands in the West. This would mean that many tribes would be relocated to areas far from their traditional territory, and often to regions that were less fertile or desirable. Many tribes resisted this relocation, such as the Cherokee, who were eventually removed and forced to march in what become known as the "Trail of Tears."

D. Jackson relies on polite, academic words, whereas Rutledge relies on rich description.
