Conspiracies against Robespierre, who had dominated the Committee of Public Safety, came together on 9 Thermidor (27 July) 1794. Jean-Lambert Tallien, a member of and previously President of the National Convention, impugned Saint-Just and then went on to denounce the tyranny of Robespierre. The attack was taken up by Jacques Nicolas Billaud-Varenne. Cries went up of "Down with the tyrant! Arrest him!" Robespierre then made his appeal to the deputies of the Right, yet failed. An order was made to arrest Robespierre and his followers.
