The Thermidorian Reaction was a coup d'état during the French Revolution against the leaders of the Jacobin Club, who had dominated the Committee of Public Safety.
Maximilien de Robespierre, head of the Jacobins and orchestrator of the Reign of Terror, kept a list of deputies from the National Convention that he planned to have executed. When the list was made public by the Assassin Arno Dorian, the National Convention arrested Robespierre under the charge of treachery, until he was rescued by his troops of the Paris Commune and taken to the Hôtel de Ville.
Robespierre was declared an outlaw and members of the National Guard, commanded by Paul Barras, were sent after him. Barras' forces overpowered the Jacobins and managed to recapture Robespierre, alongside his closest allies, Louis Antoine de Saint-Just, Georges Couthon, François Hanriot, and Augustin Robespierre. The next day, Robespierre and his allies were executed, putting an end to the Reign of Terror.
