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.
Society of Jesus
By 1700, Jesuits turned to maintaining Quebec, Montreal, and Ottawa without establishing new posts. During the Seven Years' War, Quebec fell to the English in 1759 and New France was under British control. The English barred the immigration of more Jesuits to New France. By 1763, there were only twenty-one Jesuits stationed in New France. By 1773 only eleven Jesuits remained. During the same year the English crown laid claim to New France and declared that the Society of Jesus in New France was dissolved.
