8. "Let Them Eat Cake"She probably said a lot of things she later regretted, but Marie Antoinette never suggested hungry French mothers who had no bread should eat cake. In 1766, Jean Jacques Rousseau was writing his "Confessions" when he quoted the famous saying of a great princess, which was incorrectly attributed to Marie Antoinette, Queen of France and wife of Louis XVI. But Marie Antoinette couldn't have made the statement because in 1766, she was only 11 years old.
Historians now believe that Rousseau's "great princess" may have been Marie Thérèse, the wife of Louis XIV, who reigned more than 75 years before Louis XVI and Marie Antoinette.
