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.

The War of the Polish Succession was a major European conflict sparked by a civil war in the Polish–Lithuanian Commonwealth over the succession to Augustus II the Strong, which the other European powers widened in pursuit of their own national interests. France and Spain, the two Bourbon powers, tested the power of the Austrian Habsburgs in Western Europe, as did the Kingdom of Prussia, whilst Saxony and Russia mobilized to support the eventual victor. The fighting in Poland–Lithuania resulted in the accession of Augustus III, who in addition to Russia and Saxony, was politically supported by the Habsburgs.
