On 20 September 1792 the National Convention abolished the monarchy and declared France a republic. Due to the emergency of war, the National Convention created the Committee of Public Safety, controlled by Maximilien de Robespierre of the Jacobin Club, to act as the country's executive. Under Robespierre, the committee initiated the Reign of Terror, during which up to 40,000 people were executed in Paris, mainly nobles and those convicted by the Revolutionary Tribunal, often on the flimsiest of evidence. Internal tensions at Paris drove the Committee towards increasing assertions of radicalism and increasing suspicions, fueling new terror: A few months into this phase, more and more prominent revolutionaries were being sent to the guillotine by Robespierre and his faction, for example Madame Roland and Georges Danton. Elsewhere in the country, counter-revolutionary insurrections were brutally suppressed. The regime was overthrown in the coup of 9 Thermidor (27 July 1794) and Robespierre was executed. The regime which followed ended the Terror and relaxed Robespierre's more extreme policies.
