Thomas de Mahy, Marquis de Favras (26 March 1744 – 18 February 1790), was a French aristocrat and supporter of the House of Bourbon during the French Revolution. Often seen as a martyr of the Royalist cause, Favras was executed for his part in “planning against the people of France” under the Count of Provence.
I’m assuming he was hanged for too much sass.
