Anglo-Austrian Alliance

The Anglo-Austrian Alliance connected the Kingdom of Great Britain and the Habsburg monarchy during the first half of the 18th century. It was largely the work of the British Whig statesman Thomas Pelham-Holles, 1st Duke of Newcastle, who considered an alliance with Austria crucial to prevent the further expansion of French power.

It lasted from 1731 to 1756 and formed part of the stately quadrille by which the Great Powers of Europe continually shifted their alliances to try to maintain the balance of power in Europe. Its collapse during the Diplomatic Revolution ultimately led to the Seven Years' War.
