Favras, Thomas de Mahy, marquis de

Favras, Thomas de Mahy, marquis de (tômä` də mäē` märkē` də fävräs`), 1744–90, French royalist. After the outbreak of the French Revolution, he plotted (1789) with the comte de La Châtre to steal Louis XVI away to Metz and to proclaim the comte de Provence (later Louis XVIII) regent. The plan allegedly also called for the assassination of Jean Bailly, mayor of Paris, and the marquis de Lafayette, commander of the national guard. Denounced by some of his agents, Favras was arrested, but he divulged none of the details of the plot. He was hanged in 1790 despite lack of incriminating evidence.
