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.
New France
Within Acadia and Nova Scotia, Father Le Loutre's War (1749–1755) began with the British founding of Halifax. During Father Le Loutre's War, New France established three forts along the border of present-day New Brunswick to protect it from a New England attack from Nova Scotia. The war continued until British victory at Fort Beausejour, which dislodged Father Le Loutre from the region, thereby ending his alliance with the Maliseet, Acadians and Mi'kmaq.
