Treaty of Vienna (1731)

The Treaty of Vienna was first signed on 16 March 1731 by the imperial ministers Prince Eugene of Savoy, Count Sinzendorf and Count Gundaker Thomas Starhemberg and the British envoy to Vienna, Sir Thomas Robinson. This treaty marked the collapse of the Anglo-French Alliance (1727–1731), the beginning of the Anglo-Austrian Alliance and the birth of the legend of the natural enmity between the Kingdom of France and the Kingdom of Great Britain. The treaty pitted France and Spain on one side against Great Britain and Austria on the other.

The Spanish, specifically, signed the treaty on 22 July 1731. The treaty also recognised Charles of Spain as the Duke of Parma.
