In your opinion, did the united states and native americans maintain a cooperative and mutually beneficial relationship in the period from 1783 to 1840?

No

Explanation:

Native Americans actively resisted the development and expansion of the United States. The aligned themselves with the British and Spain. Their intervention made it more difficult to find stability in the early years and affected the relations between the different parts of the union.

However, there were crucial victories for the US early on, as the treaties with the Iroquois and the Creek Indians.

As the 19th century advanced, and the US moved west, the relations became even tenser.
