Louis XVI was publicly guillotined on 21 January 1793 at the Place de la Révolution, proclaiming his innocence.

Louis's carriage arrived at the Place de la Révolution around 10:15 a.m., stopping before a scaffold between the Champs-Élysées and a pedestal where a statue of Louis XV had stood until its toppling in 1792. As he was strapped down he exclaimed, "My people, I die innocent!" and told his executioners he was innocent of everything of which he was accused. Charles-Henri Sanson, high executioner of the French First Republic and formerly royal executioner, performed the beheading; he later published an account stressing the king's composure and firmness.
