New France
In 1763, France had ceded the rest of New France, except the islands of Saint Pierre and Miquelon, to Great Britain and Spain at the Treaty of Paris, which ended the Seven Years' War (known as the French and Indian War in North America and especially the United States). Britain received Canada, Acadia, and the parts of French Louisiana which lay east of the Mississippi Riverexcept for the Île d'Orléans, which was granted to Spain, along with the territory to the westthe larger portion of Louisiana.
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.
