On this day (16 October) in 1793, Marie Antoinette was sentenced to death by a French revolutionary tribunal after a one-day sham trial. She was beheaded at 12:15 PM, and her last words were: “Pardonnez-moi, monsieur. Je ne l’ai pas fait exprès” (“Pardon me, sir, I did not do it on purpose”), after accidentally stepping on her executioner’s shoe.
