Madame Royale
It was similar to the style "Monsieur", which was typically used by the King's second son. Just as Gaston, duc d'Orléans (1608–1660), the second son of King Henry IV of France (1553–1610), was known as " Monsieur", Elisabeth of Bourbon (1602–1644), the eldest daughter of Henry, was known before her marriage to King Philip IV of Spain (1605–1665) as "Madame Royale". After her death, the title was borne by her younger sister, Christine Marie of France (1606–1663), until her marriage to Victor Amadeus I, Duke of Savoy (1587–1637).
The most famous holder of this honorific was King Louis XVI of France's eldest daughter, Marie-Thérèse-Charlotte (1778–1851), the only one of his immediate family to survive the French Revolution. She later married her cousin, Louis-Antoine, duc d'Angoulême (1775–1844), and played a prominent role during the Bourbon Restoration.
