Bourbon Family Compact

The Pacte de Famille (French pronunciation: ​[pakt də famij], Family Compact; Spanish: Pacto de Familia) is one of three separate, but similar alliances between the Bourbon kings of France and Spain.

The first of these (Primer Pacto de Familia) was made on November 7, 1733 by King Philip V of Spain and King Louis XV of France in the Treaty of the Escorial.

Philip V was the grandson of Louis XIV and had become the first Bourbon King of Spain in 1700 upon the extinction of Spanish Habsburgs. After a long war, the War of the Spanish Succession, he was recognized as king by other European powers in the Treaty of Utrecht with the condition that the thrones of Spain and France never be united. In addition, Spanish possessions in Italy were ceded to the surviving branch of the House of Habsburg.

Louis XV was Philip's nephew. He had married Maria Leszczyńska, the daughter of King Stanislaus I of Poland. Because of this marriage alliance France became involved in the War of the Polish Succession in 1733.

Philip V formed a plan to use this conflict to win back lost territory in Italy for his sons. He allied Spain to France. Because of his close relationship with Louis XV their alliance became known as the Family Compact. Louis failed to restore Stanislas to the Polish throne, but the Bourbons would gain the Duchy of Lorraine (for France) and the Kingdoms of Naples and Sicily (for Charles, the third son of King Philip V of Spain) from his conflict.
