How did American settlers spread in the eastern part of the thirteen colonies, after 1776, in the United States?

Explanation: Ever since the fall of Jamestown, colonists had to use alternative lands that didn't have as much harsher winters and had more sun so that their agriculture trade can increase throughout the East. They also spread the Eastern section of the thirteen colonies by opening more trade routes for importing and exporting to help trade crops with the Indians and other colonies of the East.

the government paid religious orders to provide basic education to native american children on reservations. in the late 19th and early 20th centuries, the bureau of indian affairs (bia) founded additional boarding schools based on the assimilation model of the off-reservation carlisle indian industrial school.
