After learning of the bread shortages that were occurring in Paris at the time of Louis XVI's coronation in Rheims, as quoted in Marie Antoinette: The Journey (2001) by Antonia Fraser, p. 135 . Tradition persists that Marie Antoinette joked "Let them eat cake!" (Qu'ils mangent de la brioche.) This phrase, however, occurs in a passage of Jean-Jacques Rousseau's Confessions, written in 1766, when Marie Antoinette was 11 years old and four years before her marriage to Louis XVI. Cf.

Context: It is quite certain that in seeing the people who treat us so well despite their own misfortune, we are more obliged than ever to work hard for their happiness. The king seems to understand this truth; as for myself, I know that in my whole life (even if I live for a hundred years) I shall never forget the day of the coronation.
