After the American Revolutionary War, the Royal Proclamation of 1763 became a dead letter in the United States, but continued in force in Rupert's Land, which later became part of Canada. The proclamation forms the basis of land claims of aboriginal peoples in Canada – First Nations, Inuit, and Métis. The Royal Proclamation of 1763 is mentioned in the Canadian Charter of Rights and Freedoms.
Besides restricting colonial expansion, however (colonial land grants were generally accepted to stretch in an unbroken strip along the continent), the Proclamation dealt with the management of newly ceded French colonies. It established government for four areas: Quebec, West Florida, East Florida, and Grenada. All of these were granted the ability to elect general assemblies under a royally appointed governor and high council, which could then create laws and ordinances specific to the area in agreement with British and colonial laws. In the meantime, the new colonies enjoyed the same rights as native-born Englishmen, something that British colonists had been fighting over for years. An even bigger affront to the British colonies was the establishment of both civil and criminal courts complete with the right to appeal; those being tried for breaking the Stamp or Sugar Act were tried instead in admiralty court, where the defendant was considered guilty until he or she could prove their innocence.
A reform that would have benefited the British colonists was the opening of Indian trade to all. With a free license in hand, a colonist could trade at will- of course, they would have to acknowledge British authority on Indian trade regulation, something many were happy to ignore.
