War of the Quadruple Alliance

1718–1720

Philip V of Spain and his minister Cardinal Alberoni set out to win back the Italian lands Spain had lost at the end of the War of the Spanish Succession. A Spanish army took Sardinia in 1717 and landed in Sicily in 1718. Britain, France, Austria and the Dutch Republic joined in the Quadruple Alliance to stop it, and a British fleet under Admiral Sir George Byng sailed into the Mediterranean, met the Spanish fleet off Cape Passaro at the southern tip of Sicily, and destroyed it before war had even been declared. With its army cut off in Sicily, Spain gave in, and Alberoni was dismissed.
