Pacte de Famille
series of 3 alliances (1773, 1743, 1761) between the Bourbon kings of France and Spain
The Pacte de Famille (French pronunciation: [pakt də famij], Family Compact; Spanish: Pacto de Familia) is three separate, but similar alliances between the Bourbon kings of France and Spain. As part of the settlement of the War of the Spanish Succession that brought the House of Bourbon of France to the throne of Spain, Spain and France made a series of agreements that did not unite the two thrones, but did lead to cooperation and military alliance on a defined basis. The Bourbon alliance would be broken by the French Revolutionary Wars.
The first Pacte de Famille, 1733
The first of the three Pacto de Familia was agreed on November 7, 1733, between Philip V of Spain and his nephew Louis XV of France, in the Treaty of the Escorial.
The War of the Spanish Succession was fought to prevent a dynastic union of France and Spain; this meant despite their close family ties, the two countries were opponents in the 1718 to 1720 War of the Quadruple Alliance. When Cardinal Fleury became French chief minister in 1726, he sought a closer relationship with Spain. This was made easier by the birth of Louis' heir in 1729, which seemed to ensure the two would remain separate.
Louis's wife, Maria Leszczyńska, was the daughter of Stanisław Leszczyński, former King of Poland, deposed by Augustus II in 1709. After Augustus's death in February 1733, Louis saw an opportunity to weaken Austria by backing his father-in-law to regain the throne.
Philip, now married to his second wife, Elisabeth Farnese, wanted to regain Spanish territories in Naples and Sicily, ceded to Austria in 1714, in part so that Elisabeth's first-born son Charles, unlikely to succeed to the throne of Spain because he had two older half-brothers in line before him, would have territories to rule as king.
