In 1737, the Emperor embarked on another Turkish War in alliance with Russia. Unlike the previous Austro-Turkish War, it ended in a decisive Austrian defeat. Much of the territory gained in 1718 (Except for the Banat) was lost. Popular discontent at the costly war reigned in Vienna; Francis of Lorraine, Maria Theresa's husband, was dubbed a French spy by the Viennese. The war not only revealed the sorry state of the Austrian army, but also the weakness of the imperial state itself, which did not have the financial strength to sustain a long war without the subsidies of its allies.
