New France
New France () was the area colonized by France in North America during a period beginning with the exploration of the Gulf of Saint Lawrence by Jacques Cartier in 1534 and ending with the cession of New France to Great Britain and Spain in 1763 under the Treaty of Paris (1763).
Colonial history of the United States
New France was the vast area centered on the Saint Lawrence river, Great Lakes, Mississippi River and other major tributary rivers that was explored and claimed by France starting in the early 17th century. It was composed of several colonies: Acadia, Canada, Newfoundland, Louisiana, Île-Royale (present-day Cape Breton Island), and Île Saint Jean (present-day Prince Edward Island). These colonies came under British or Spanish control after the French and Indian War, though France briefly re-acquired a portion of Louisiana in 1800. The United States would gain much of New France in the 1783 Treaty of Paris, and the U.S. would acquire another portion of French territory with the Louisiana Purchase of 1803. The remainder of New France became part of Canada, with the exception of the French island of Saint Pierre and Miquelon.
