The British government also came to the conclusion that colonists and Indians must be kept apart. On October 7, 1763, the Crown issued the Royal Proclamation of 1763, an effort to reorganize British North America after the Treaty of Paris. The Proclamation, already in the works when Pontiac's War erupted, was hurriedly issued after news of the uprising reached London. Officials drew a boundary line between the British colonies and American Indian lands west of the Appalachian Mountains, creating a vast "Indian Reserve" that stretched from the Appalachians to the Mississippi River and from Florida to Quebec. By forbidding colonists from trespassing on Indian lands, the British government hoped to avoid more conflicts like Pontiac's War. "The Royal Proclamation," writes Calloway (2006), "reflected the notion that segregation not interaction should characterize Indian-white relations."
