The answer is that a peace treaty was signed, but the settlers did not follow it.
The British Government came to the conclusion that settlers and Indians should remain separate. On October 7, 1763, the Crown drafted the Royal Decree of 1763, through which he wanted to reorganize the North American territories
The officers drew a line of separation between the British colonies and the lands of the natives west of the Appalachian Mountains, creating an immense Indian Reservation that ranged from the Appalachians to the Mississippi River and from Florida to Newfoundland. By prohibiting settlers from entering Indian lands, the British government hoped to avoid new events such as the Pontiac Rebellion.
The effects of the Pontiac war were noted for a long time. Because the Decree recognized some indigenous rights over the lands they occupied, it became known as the Indian Bill of Rights.
However, the Royal Decree of 1763 did not prevent the British from attempting to expand westward, so the Indians were forced to form new resistance movements. The first began in 1767 after a meeting organized by the Shawnee.
