It was known for short as the Commission of Twelve and its formation led to the revolt of 2 June 1793, the fall of the Girondins and the start of the Reign of Terror.
This new commission had been requested by Barère and was put in charge of looking into all decisions taken over the past month by the conseil général of the Commune and sections of Paris and unmasking all plots against liberty within the Republic.
On 21 May the commission was elected, with a very strong Girondin majority: Jean-Baptiste Boyer-Fonfrède, Jean-Paul Rabaut Saint-Étienne, Kervélégan, Charles Saint-Martin-Valogne, Louis-François-Sébastien Viger, Jean-René Gomaire, Bertrand de la Hosdinière, Jacques Boilleau, Étienne Mollevaut, Henry-Larivière, François Bergoeing and Jean-François Martin Gardien.
Then a deputation from the 22 sections of Paris came to demand that the Convention end the commission and put its members on trial before the revolutionary tribunal.
On 2 June the members of the sections, under the orders of Hanriot, provisional commander of the National Guard, gathered and marched on the convention.
The Convention descended into the courtyard and its president Hérault de Séchelles proclaimed the representatives' order enjoining the armed force to retire.
