Britain, Holland, Spain and the Emperor sign the Treaty of Vienna
to avert an international war over the Italian duchies. By the
terms of this treaty, the British and Dutch guarantee the Pragmatic
Sanction, Spain obtains Parma and Piacenza, and the Austria East
India Company is to be finally abolished (originally the treaty was
drafted in March but Spain refused to sign). By a secret clause
England insists that Maria Theresa, daughter of the Emperor, shall
not marry a Bourbon.
