New France was a vast territory colonized by France in North America from 1534 to 1763. It extended from Newfoundland to the Canadian Prairies and from Hudson Bay to the Gulf of Mexico, including all the Great Lakes of North America. The main regions of New France included Canada (with districts like Quebec, Trois-Rivières, and Montreal), Acadia, Hudson Bay, Terre-Neuve (Newfoundland), and Louisiana. The territory was centered around the St. Lawrence River, which served as a key route for French influence. After the Seven Years' War, New France was ceded to Great Britain and Spain, ending French colonial control in mainland North America, though some small islands like Saint Pierre and Miquelon remain French possessions today.
