The Province of Quebec was a colony in North America created by Great Britain after the Seven Years' War. Great Britain acquired French Canada by the Treaty of Paris in which (after a long debate) France negotiated to keep the small but very rich sugar island of Guadeloupe instead. By Britain's Royal Proclamation of 1763, Canada (part of New France) was renamed the Province of Quebec. The new British province extended from the coast of Labrador on the Atlantic Ocean, southwest through the Saint Lawrence River Valley to the Great Lakes and beyond to the confluence of the Ohio and Mississippi Rivers. Portions of its southwest (below the Great Lakes) were later ceded to the United States in a later Treaty of Paris (1783) at the conclusion of the American Revolution.
