Prior to the American Revolution, Great Britain had adopted a policy of minimal interference with Native American tribes. After the French and Indian War, the British imposed the Proclamation Line of 1763 on the American colonists. This line restricted the colonists from settling west of the Appalachian Mountains, thus minimizing conflicts with Native American groups. Many Native American groups sided with the British during the American Revolution because colonists had repeatedly attempted to settle in Native American territory. The British appeared to be the party more willing to restrict westward movement and preserve the territory of the Native Americans. However, there were some tribes that did side with the Americans.
