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.
French Louisiana
Colonial French Louisiana was a part of New France. Beginning in 1682 this region, known in French as "la Louisiane française", functioned as an administrative district of New France. It extended from the Gulf of Mexico to Vincennes, now in Indiana. France ceded the region to Spain and Britain in 1763 after the French and Indian War, regained it by treaty in 1800, and sold it to the United States in 1803 through the Louisiana Purchase.
