king permitted and by engaging in personal politics more beneficial to the Dauphiné than to France. For example, he married Charlotte of Savoy against his father's wishes. Savoy was a traditional ally of the Dauphiné, and Louis wished to reaffirm that alliance to stamp out rebels and robbers in the province. Louis was driven out of the Dauphiné by Charles VII's soldiers in 1456, leaving the region to fall back into disorder. After his succession as Louis XI of France in 1461, Louis united the Dauphiné with France, bringing it under royal control. The title was automatically conferred upon the next heir apparent to the throne in the direct line upon birth, accession of the parent to the throne or death of the previous Dauphin, unlike the British title Prince of Wales, which has always been in the gift of the monarch (traditionally conferred upon the heir's 21st birthday). The sons of the King of France held the style and rank of fils de France (son of France), while male-line grandsons were given the style and rank of petits-enfants de France (Grandson of France). The sons and grandsons of the Dauphin ranked higher than their cousins, being treated as the king's children and grandchildren respectively. The sons of the Dauphin, though grandsons of the king, were ranked as Sons of France, and the grandsons of the Dauphin ranked as Grandsons of France; other great-grandsons of the king ranked merely as princes of the blood. The title was abolished by the Constitution of 1791, which made France a constitutional monarchy. Under the constitution the heir-apparent to the throne (Dauphin Louis-Charles at that time) was restyled Prince Royal (a Prince of the Blood retitled prince français), taking effect from the inception of the Legislative Assembly on 1 October 1791. The title was restored in potentia under the Bourbon Restoration of Louis XVIII, but there would not be another Dauphin until after his death. With the accession of his brother Charles X, Charles' son and heir Louis-Antoine, Duke of Angoulême automatically became Dauphin. With the removal of the Bourbons the title fell into disuse, the heirs of Louis-Philippe being titled Prince Royal. After the death of Henri, comte de Chambord, Carlos, Duke of Madrid, the heir of the legitimist claimant, Juan, Count of Montizón, made use of the title in pretense, as have the Spanish legitimist claimants since.
