The Reign of Terror ended when Maximilien Robespierre and his allies were overthrown and executed in July 1794, in an event known as the Thermidorian Reaction.

Quick Scoop: What Ended the Reign of Terror?

  • The Reign of Terror ran roughly from September 1793 to July 1794 during the French Revolution.
  • It was driven by the radical Jacobins and the Committee of Public Safety, led in large part by Robespierre.
  • The Terror ended when Robespierre lost political support, was arrested, and then executed on 27–28 July 1794 (9–10 Thermidor Year II in the revolutionary calendar).

Step‑by‑Step: How It Came to an End

  1. Military success removed the excuse for terror
    • In June 1794, France won a major victory at the Battle of Fleurus, easing the foreign invasion threat.
 * With the external danger reduced, many politicians felt that extreme emergency measures and mass executions were no longer justified.
  1. Growing fear of Robespierre
    • Robespierre continued to defend harsh policies and denounce “enemies of the revolution,” even within the Convention.
 * Deputies in the National Convention feared that they could be the next victims of the guillotine, which pushed former rivals to unite against him.
  1. The crisis of Thermidor (July 1794)
    • On 9 Thermidor Year II (27 July 1794), members of the National Convention turned on Robespierre, shouting him down and voting for his arrest along with several close allies like Saint‑Just.
 * After a failed attempt by supporters in the Paris Commune to rescue them, Robespierre and his followers were seized again.
  1. Execution of Robespierre and his allies
    • On 10 Thermidor (28 July 1794), Robespierre was guillotined, along with key associates such as Saint‑Just.
 * His death is widely taken as the turning point that ended the Reign of Terror.

What Changed After the Terror?

  • The fall of Robespierre is called the Thermidorian Reaction , a shift away from radical Jacobin rule toward a more moderate phase of the Revolution.
  • Revolutionary tribunals slowed, mass executions dropped sharply, and many Jacobin clubs were closed or purged.
  • Power moved from radical sans‑culotte allies to more moderate and conservative revolutionaries, setting the stage for later governments like the Directory.

Forum‑Style Take: Why Did It Really End?

Some historians say the Terror collapsed because it “ate its own leaders”: once Robespierre started threatening fellow deputies, they struck first.

Others stress the military victory at Fleurus: once France was safer, the political cost of continued executions outweighed any benefit.

Many modern discussions also point out the irony: the man who justified terror as necessary to protect liberty was himself executed as a tyrant, and his fall became the symbol of the Terror’s end.

TL;DR:
The Reign of Terror ended in July 1794 when fearful deputies in the National Convention overthrew and executed Robespierre and his allies in the Thermidorian Reaction, then rolled back the radical, violent policies of Jacobin rule.
