The Revolutionary Tribunal (French: Tribunal révolutionnaire) was a court which was instituted in Paris by the Convention during the French Revolution for the trial of political offenders, and eventually became one of the most powerful engines of the Reign of Terror. It was composed of a jury, a public prosecutor, and two substitutes, all nominated by the Convention; and from its judgments there was no appeal. With M.J.A. Herman as president and Fouquier-Tinville as public prosecutor, the tribunal terrorized the royalists, the refractory priests and all the actors in the counter-revolution.
