The Anglo-Austrian Alliance connects the Kingdom of Great Britain and the Habsburg monarchy during the first half of the 18th century.
It is largely the work of the British diplomat the Duke of Newcastle, who considers an alliance with Austria crucial to prevent the further expansion of French power.It lasts from 1731 to 1756 and forms part of the stately quadrille by which the Great Powers of Europe continually shift their alliances to try to maintain the balance of power in Europe.
Its collapse during the Diplomatic Revolution ultimately leads to the Seven Years' War.
