Please I need help with my LEQ. Will mark it as the brainiest! Prompt: How and why did relations between the United States and American Indian nations change between 1830 and 1900?

1775–1830

U.S. Indian policy during the American Revolution was disorganized and largely unsuccessful. At the outbreak of the war, the Continental Congress hastily recruited Indian agents. Charged with securing alliances with Native peoples, these agents failed more often than they succeeded. They faced at least three difficulties. First, they had less experience with Native Americans than did the long-standing Indian agents of the British Empire. Second, although U.S. agents assured Indians that the rebellious colonies would continue to carry on the trade in deerskins and beaver pelts, the disruptions of the war made regular commerce almost impossible. Britain, by contrast, had the commercial power to deliver trade goods on a more regular basis. And third, many Indians associated the rebellious colonies with aggressive white colonists who lived along the frontier. Britain was willing to sacrifice these colonists in the interests of the broader empire (as it had done in the Proclamation of 1763), but for the colonies, visions of empire rested solely on neighboring Indian lands. Unable to secure broad alliances with Indian peoples, U.S. Indian policy during the Revolution remained haphazard, formed by local officials in response to local affairs.

it would take 95 years for that supernova to be visible on earth, so the year would be about 2113. i hope i did my calculation right.
