The treaty was marked by the mutual restitution of conquests, including the fortress of Louisbourg on Cape Breton Island, Nova Scotia, to France; Madras in India, to England; and the barrier towns to the Dutch. The right of the Habsburg heiress Maria Theresa to the Austrian lands was guaranteed, but the Habsburgs were seriously weakened by the guarantee to Prussia, not a party to the treaty, of its conquest of Silesia. Both Britain and France were trying to win the friendship of Prussia, now clearly a significant power, for the next war. Maria Theresa gave up to Spain the duchies of Parma, Piacenza, and Guastalla in Italy.
