The war of the Austrian Succession (1740-1748) also known as King George's War in North America, and incorporating the war of Jekins' Ear with Spain and two of the three Silesian wars involved nearly all the powers of Europe, except for the Polish-Lithunian Commonwealth, Portuguse and the Ottoman Empire. The war began under the pretext that Maria Theresa of Austria was ineligible to succeed to the Habsburg thrones of her father, Charles VI, because Salic law precluded Royal inheritance by a woman, though in reality this was a convenient excuse put forward by Prussia and France to challenge Habsburg power.
Austria was supported by Great Britain and the Dutch Republic, the traditional enemies of France , as well as the Kingdom of Sardinia and Saxony. France and Prussia were allied with the electorate of Bavaria. The war ended with the Treaty of Aix-la-Chapelle in 1748.
