I am Louis, Dauphin of France, I was the elder and only surviving son of King Louis XV of France and his wife, Queen Marie Leszczyńska. As a son of the king, I was a fils de France. As heir apparent, I became Dauphin of France. Although I died before ascending to the throne myself, all three of my sons who made it to adulthood were to later rule France: Louis XVI (reign in 1774–1792), Louis XVIII (1814–1815, again in 1815–1824) and Charles X (1824–1830).
