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.

Voltaire's famous quotations about New France were for the most part written between 1753 and 1763, shortly before, and then during, the Seven Years' War. Voltaire was living in Switzerland during most of this period. During the war, he sometimes appeared to favor the Prussian king Frederick II (allied to Britain against France), with whom he was maintaining a regular personal correspondence during the war (the two men being again in better terms after their quarrel of 1753). Voltaire was also at the same time in correspondence with some French ministers. He thus corresponded with both sides of the belligerents in the war, although mostly on a personal and literary level more than a political level. He thought that the war was a mistake for France and he used several opportunities to ask the French ministers to simply quit the war. Boundary disputes in their American colonies had been an early (1754) between Britain and France in this war, which was later (1756) further complicated by purely European considerations and ended seven years later (1763). Voltaire's position that France should let go of its North American colonies was in accord with his position about the war in general. For him, handing over New France would appease Britain. His position about the European war likely increased his tendency to paint New France as being of little value.
