In 1343, a series of negotiations was initiated between dauphinHumbert II of Viennois and the French kingPhilippe VI, regarding the future inheritance of the Dauphiné. Since Humbert had no heirs, it was initially agreed that in exchange for a substantial financial compensation, his domains will pass to king's younger sonPhilip, Duke of Orléans, but already in 1344 the provisions were changed by the new agreement, designating king's oldest son and heirJohn, Duke of Normandy as Humbert's heir in the Dauphiné.[3]
By 1349, Humbert decided to relinquish his rule over Dauphiné, and the final agreement was made, designating king's grandson and John's sonCharles as Humbert's successor, on the condition that Dauphiné will remain a distinctive polity, not integrated into the French realm. Thus in the summer of 1349, the young French prince Charles became the firstDauphin de Viennois from theHouse of Valois. In 1350, when his father ascended to the French throne as king John II, Charles became theheir presumptive and thus for the first time both honors (heir to the French throne, and Dauphin de Viennois) were held by the same person.[4]
The title was roughly equivalent to the SpanishPrince of Asturias, the PortuguesePrince of Brazil, the English (later British)Prince of Wales, the DutchPrince of Orange, and the ScottishDuke of Rothesay. The official style of a Dauphin of France, prior to 1461, waspar la grâce de Dieu, dauphin de Viennois, comte de Valentinois et de Diois ("By the Grace of God, Dauphin of Viennois, Count of Valentinois and of Diois"). A Dauphin of France united the coat of arms of the Dauphiné, which featured dolphins, with the Frenchfleurs-de-lis, and might, where appropriate, further unite that with other arms (e.g.Francis, son ofFrancis I, was rulingDuke of Brittany, so united the arms of that province with the typical arms of a Dauphin;Francis II, while Dauphin, was also King of Scots by marriage toMary I, and added the arms of theKingdom of Scotland to those of the Dauphin).
Originally the Dauphin was personally responsible for the rule of theDauphiné, which was legally part of theHoly Roman Empire, and which the emperors, in giving the rule of the province to the French heirs, had stipulated must never be united with France. Because of this, the Dauphiné suffered from anarchy in the 14th and 15th centuries, since the Dauphins were frequently minors or concerned with other matters.
During his period as Dauphin, Louis, son ofCharles VII, defied his father by remaining in the province longer than the king permitted and by engaging in personal politics more beneficial to the Dauphiné than to France. For example, he marriedCharlotte 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 asLouis XI 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 titlePrince 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 offils de France (son of France), while male-line grandsons were given the style and rank ofpetits-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 asprinces of the blood.
The title was abolished by theConstitution of 1791, which made France a constitutional monarchy. Under the constitution the heir-apparent to the throne (DauphinLouis-Charles at that time) was restyledPrince Royal (aPrince of the Blood retitledprince français), taking effect from the inception of theLegislative Assembly on 1 October 1791. The title was restoredin potentia under theBourbon Restoration ofLouis XVIII, but there would not be another Dauphin until after his death. With the accession of his brotherCharles X, Charles' son and heirLouis-Antoine, Duke of Angoulême automatically became Dauphin.
Louis, Duke of Guyenne, the Dauphin of Viennois, is a character inWilliam Shakespeare'sHenry V. Another Shakespeare play,King John, features the futureLouis VIII as "Lewis the Dauphin" - this is an anachronisms, as he died over a century before the term was applied to French heirs-apparent.
"The Dauphin" is a 1988 episode ofStar Trek: The Next Generation. As the titular character (a planetary princess) is female, the episode title gets the gender incorrect (the French female equivalent is "Dauphine").
