King Philip V of Spain had always aimed to reconquer Naples and Sicily, which Spain lost to the Habsburgs as a consequence of the War of the Spanish Succession. In 1714 he married Elisabeth Farnese, who had dynastic interests in Italy. Under her influence he had attempted without success to recover the Italian holdings in the War of the Quadruple Alliance. When the War of the Polish Succession broke out in 1733, he saw an opportunity to act against the Habsburgs, who had no military support among western European powers (Great Britain and the Dutch Republic opting to remain neutral), with active opposition by France and Charles Emmanuel III of Sardinia. In the fall of 1733 Spain and France signed the Treaty of the Escorial, the first of several Bourbon Family Compacts. The treaty pledged mutual protection and aid, and provided for the allies to work together for the conquest of Habsburg territories on the Italian peninsula.
