How old was Marie Antoinette when she married Louis-Auguste?
May 16 - 1770 – Marie Antoinette marries Louis-Auguste, who later becomes king of France.
Marie Antoinette was only 14 years old when she married 15-year-old Louis-Auguste, the future Louis XVI. To seal the newfound alliance between longtime enemies Austria and France that had been forged by the Seven Years' War, the Austrian monarchs offered the hand of their youngest daughter to the heir apparent to the French throne, Dauphin Louis-Auguste. On May 7, 1770, the 14-year-old royal bride was delivered to the French on an island in the middle of the Rhine River, and a grand procession escorted the archduchess to the Palace of Versailles. The day after Marie Antoinette met the 15-year-old future king of France, the two were wed in a lavish palace ceremony.
