“Marie Antoinette (1700’s): Let them eat cake”
This was a lie spread by the revolutionaries to stir up the populace. What she said in reality was “Let them eat the cakes in our kitchen”.
Marie Antoinette was well known to be kind and innocent, and they paint them as a cynical and insensitive jerk. A lie repeated enough to become truth.
Leftists always make fake news, then and now.
