The Proclamation of 1763, also known as the Royal Proclamation of 1763, was issued by King George III on October 7, 1763. It was created following the Treaty of Paris that ended the Seven Years' War, which transferred French territory in North America to Great Britain. The proclamation established administrative structures for the new territories and set guidelines for European settlement, particularly forbidding colonial settlers from settling west of the Appalachian Mountains. This boundary, known as the Proclamation Line, was designed to reserve lands west of the Appalachians for Indigenous peoples and prevent encroachment by settlers. The proclamation recognized Indigenous land rights by stating that lands west of the line were "Indian Territories" where Indigenous peoples should not be disturbed, and it prohibited private land purchases from Indigenous groups, requiring such transactions to go through the Crown. It was aimed at organizing Britain's new territories, controlling westward colonial expansion, and managing relations with Indigenous nations. This document is significant historically both as a colonial policy and as a foundation for Indigenous rights in Canada. It laid the groundwork for treaty-making processes and is recognized in Canadian constitutional law as a protection of Indigenous rights.
