For some historians, the Reign of Terror commenced with the execution of Louis XVI in January 1793. Others date it to the formation of the Revolutionary Tribunal (March 1793), the expulsion of Girondinist deputies from the National Convention (June 1793) or the murder of Jean-Paul Marat (July 1793).
The Great Terror that followed, in which about 1,400 persons were executed, contributed to the fall of Robespierre on July 27 (9 Thermidor). During the Reign of Terror, at least 300,000 suspects were arrested; 17,000 were officially executed, and perhaps 10,000 died in prison or without trial.
