The Diplomatic Revolution of 1756 was the reversal of longstanding alliances in Europe between the War of the Austrian Succession and the Seven Years' War. Austria went from an ally of Britain to an ally of France; the Dutch Republic, a long-standing British ally, became more anti-British and took a neutral stance while Prussia became an ally of Britain. The most influential diplomat involved was an Austrian statesman, Wenzel Anton von Kaunitz. The change was part of the stately quadrille, a constantly shifting pattern of alliances throughout the 18th century to preserve or upset the European balance of power.
