The British conquered New France by 1760 with the fall of Quebec. France formally ceded New France to the British in the Treaty of Paris of 1763. The same year, King George III issued the Royal Proclamation of 1763, which established the western and northern boundary of the Province of New York at the limits of the Hudson, Mohawk and Delaware River watersheds. The area between that boundary and the Great Lakes and Saint Lawrence River, including west of the Appalachian Mountains, was to be the Indian Reserve.
