I am Marie-Thérèse, Duchess of Angoulême, I was the eldest child of King Louis XVI and Queen Marie Antoinette of France, and their only child to reach adulthood. In 1799, I married my cousin Louis Antoine, Duke of Angoulême, the eldest son of Charles, Count of Artois, henceforth becoming the Duchess of Angoulême. I was briefly Queen of France in 1830.
