On the 18th of October the definitive treaty was concluded at Aix-la-Chapelle.

France generously restored all her conquests, without claiming other advantages beyond the assurance of the duchies of Parma and Piacenza to the Infante Don Philip, son-in-law of Louis XV.

England surrendered to France the Island of Cape Breton and the colony of Louisbourg, the only territory she had preserved from her numerous expeditions against the French colonies and from the immense losses inflicted upon French commerce.
The Great Frederic kept Silesia; the King of Sardinia the territories already ceded by Austria.

Only France had made great conquests; and only she retained no increment of territory.

She recognized the Pragmatic-Sanction in favor of Austria and the Protestant succession in favor of George II.
