The Revolutionary Tribunal was a court instituted by the National Convention during the French Revolution for the trial of political offenders. In October 1793, it became one of the most powerful engines of the period often called the Reign of Terror.

The National Convention was the constituent assembly of the Kingdom of France for one day and the French First Republic for its first three years during the French Revolution, following the two-year National Constituent Assembly and the one-year Legislative Assembly. Created after the great insurrection of 10 August 1792, it was the first French government organized as a republic, abandoning the monarchy altogether. The Convention sat as a single-chamber assembly from 20 September 1792 to 26 October 1795.
