The Royal Proclamation of 1763 was a decree issued by King George III of Britain following the conclusion of the Seven Years' War. It aimed to organize Britain's North American territories and establish relations with Indigenous peoples. The proclamation restricted colonial expansion westward beyond the Appalachian Mountains, reserving that land for Indigenous nations to prevent conflicts.
The primary cause of the Royal Proclamation was the need to stabilize relations with Native American tribes after the war and to improve management of the newly acquired territories from France, as tensions and conflicts with Indigenous groups were rising due to colonial encroachment on their lands.
