Austrian empress Maria Theresa succeeded in bringing about a favorable conclusion for her in the 1740 to 1748 war for recognition of her succession to the throne. However, Silesia was permanently lost to Prussia as a consequence of the Silesian Wars and the Seven Years' War. The 1763 Treaty of Hubertusburg ruled that Austria and Saxony had to relinquish all claims to Silesia. Prussia, that had nearly doubled its territory was eventually recognized as a great European power with the consequence that the politics of the following century were fundamentally influenced by German dualism, the rivalry of Austria and Prussia for supremacy in Central Europe.
