The Reign of Terror began in France when Bertrand Barère, a member of the Committee of Public Safety, made a speech in favour of it that ended with the exclamation, “Let’s make terror the order of the day!”
Although there is debate amongst historians regarding the exact date that the Reign of Terror began, Barère made his speech at a time that Paris Commune was agitating for a more proactive approach against enemies of the revolution. Less than two weeks later the National Convention passed the Law of Suspects. This led to the arrest of both declared and suspected opponents of the government. This was one of the key causes of the more than 16,000 executions that took place during the Terror.
The following February Robespierre himself justified the government’s policy as ‘nothing more than speedy, severe and inflexible justice’. While some historians disagree with Robespierre’s argument that the Terror was necessary to combat counter-revolutionary elements in French society, there can be little doubt that France’s fortunes improved during its time.
However, the Terror had also begun to face opposition. By the end of 1793 two factions – one calling for an escalation, the other for moderation – had emerged. Although the leaders of both groups were executed, Robespierre’s dominance of the Committee of Public Safety was now seen as a threat to the National Convention itself.
In the session on 27 July 1794, members of the Convention turned against Robespierre and his allies. Shouts of “Down with the tyrant! Arrest him!” were heard in the chamber. Robespierre and 21 followers were arrested, and later executed, in what became known as the Thermidorian Reaction.
