The American Revolution didn't affect directly the Native Americans. It affected them because when the colonists won, it was official they had lost vast territories and would have to share land extensions with colonists. The Proclamation of 1763 wasn't so forceful after the war, because the colonists were independent from the King and he couldn't give them orders anymore. The Proclamation of 1763 kept colonists east of the Appalachian Mountains, just so you remember. France owed a large piece of land that was west of the Appalachian, and the colonists eventually bought it. Further on, they also took hold of the area around California and Florida. So as you see, the Natives were being taken away from lands and this led them to live in reservations. Nowadays, natives can live anywhere they want but many choose to live in reservations.
