Any pretense that France might maintain or regain control over the remnants of Acadia came to an end with the fall of Montreal in 1760 and the 1763 Treaty of Paris, which permanently ceded almost all of eastern New France to Britain. In 1763, Britain would designate lands west of the Appalachians as the "Indian Reserve", but did not respect Mi'kmaq title to the Atlantic region, claiming title was obtained from the French. The Mi'kmaq remain in Acadia to this day. After 1764, many exiled Acadians finally settled in Louisiana, which had been transferred by France to Spain at the end of the French and Indian War. The demonym "Acadian" developed into "Cajun," which was first used as a pejorative term until its later mainstream acceptance.
