The Proclamation of 1763 had a significant effect on colonial expansion by prohibiting British settlement west of the Appalachian Mountains, aiming to stabilize relations with Native American tribes. Issued after the French and Indian War, it was intended to prevent further conflicts between settlers and Indigenous populations. Colonists, eager for land and economic opportunity, were frustrated by this restriction, which fueled resentment toward British authority. The Proclamation contributed to growing tensions between Britain and its colonies, ultimately escalating conflicts that would lead to the American Revolution as settlers sought to ignore these boundaries and expand westward.
