 The match was negotiated as part of the Treaty of Turin, which ended Franco-Savoyard conflict during the Nine Years' War.The couple were the parents of two dauphins of France, Louis, Duke of Brittany, who died in 1712, and Louis, Duke of Anjou, the future Louis XV.In 1710, his eldest (and favourite) surviving daughter Louise Élisabeth d'Orléans married her first cousin Charles, Duke of Berry; he was a son of the Dauphin and thus outranked Philippe and his wife; this meant that Louise Élisabeth took precedence over her parents.
